database/schema/processors/sqlite.go (3)
28-29: Improve column handling robustness.The current implementation has two potential issues:
- No validation for empty column strings
- Simple string splitting might be fragile if column names contain commas
Consider adding validation and using a more robust column parsing mechanism:
- Columns: strings.Split(dbIndex.Columns, ","), + Columns: parseAndValidateColumns(dbIndex.Columns), Name: strings.ToLower(dbIndex.Name),
35-39: Add warning for dropped primary keys.The method silently filters out primary keys when multiple are present. This behavior should be logged to help with debugging.
if primaryCount > 1 { + // Log warning about dropping primary keys + log.Printf("Warning: Found %d primary keys, removing all primary key constraints", primaryCount) indexes = collect.Filter(indexes, func(index schema.Index, _ int) bool { return !index.Primary }) }
1-42: Consider adding documentation about the processor's role.The
Sqliteprocessor implements index processing for SQLite databases, but its role and responsibilities in the larger SQLite driver implementation should be documented. This would help maintainers understand:
- How it fits into the database schema management system
- What constraints and limitations apply to SQLite indexes
- Why certain design decisions (like primary key handling) were made
Consider adding package-level documentation or a detailed comment block above the
Sqlitestruct explaining these aspects.database/schema/processors/postgres.go (2)
16-25: Consider enhancing column name processing.The implementation looks good, but could be more robust in handling column names:
func (r Postgres) ProcessIndexes(dbIndexes []DBIndex) []schema.Index { var indexes []schema.Index for _, dbIndex := range dbIndexes { + columns := strings.Split(dbIndex.Columns, ",") + // Clean column names + for i, col := range columns { + columns[i] = strings.TrimSpace(col) + } indexes = append(indexes, schema.Index{ - Columns: strings.Split(dbIndex.Columns, ","), + Columns: columns, Name: strings.ToLower(dbIndex.Name), Type: strings.ToLower(dbIndex.Type), Primary: dbIndex.Primary, Unique: dbIndex.Unique, }) }
16-25: Well-structured separation of concerns.The change from
[]schema.Indexto[]DBIndexis a good architectural decision that:
- Clearly separates database-specific and schema-generic representations
- Makes the code more maintainable as each database driver can have its own index representation
- Provides a cleaner interface for the new SQLite driver integration
database/schema/processors/sqlite_test.go (2)
11-28: Consider enhancing test structure and coverage.While the test is functional, consider these improvements:
- Use subtests with
t.Run()for better test organization and clearer failure messages- Add validation for index types (BTREE vs HASH)
- Convert to table-driven tests for better maintainability
- Add negative test cases for malformed input
Here's a suggested refactor:
func TestSqliteProcessIndexes(t *testing.T) { - // Test with valid indexes - input := []DBIndex{ - {Name: "INDEX_A", Type: "BTREE", Columns: "a,b"}, - {Name: "INDEX_B", Type: "HASH", Columns: "c,d"}, - {Name: "INDEX_C", Type: "HASH", Columns: "e,f", Primary: true}, - } - expected := []schema.Index{ - {Name: "index_a", Columns: []string{"a", "b"}}, - {Name: "index_b", Columns: []string{"c", "d"}}, - {Name: "index_c", Columns: []string{"e", "f"}, Primary: true}, - } - - sqlite := NewSqlite() - result := sqlite.ProcessIndexes(input) - - assert.Equal(t, expected, result) + tests := []struct { + name string + input []DBIndex + expected []schema.Index + wantErr bool + }{ + { + name: "valid indexes with different types", + input: []DBIndex{ + {Name: "INDEX_A", Type: "BTREE", Columns: "a,b"}, + {Name: "INDEX_B", Type: "HASH", Columns: "c,d"}, + {Name: "INDEX_C", Type: "HASH", Columns: "e,f", Primary: true}, + }, + expected: []schema.Index{ + {Name: "index_a", Columns: []string{"a", "b"}}, + {Name: "index_b", Columns: []string{"c", "d"}}, + {Name: "index_c", Columns: []string{"e", "f"}, Primary: true}, + }, + }, + { + name: "malformed column string", + input: []DBIndex{ + {Name: "INDEX_A", Type: "BTREE", Columns: "a,"}, + }, + wantErr: true, + }, + } + + sqlite := NewSqlite() + for _, tt := range tests { + t.Run(tt.name, func(t *testing.T) { + result := sqlite.ProcessIndexes(tt.input) + if tt.wantErr { + assert.Nil(t, result) + } else { + assert.Equal(t, tt.expected, result) + } + }) + }
29-44: Add documentation explaining multiple primary key handling.The test case verifies that extra primary keys are excluded, but it's not immediately clear why this is the expected behavior. Please add a comment explaining the SQLite constraint or design decision that drives this requirement.
- // Test with valid indexes with multiple primary keys + // Test with multiple primary keys + // SQLite only supports one primary key per table, so additional primary keys + // should be excluded from the processed indexes input = []DBIndex{database/schema/processors/postgres_test.go (1)
Line range hint
11-89: Consider adding SQLite-specific edge casesSince this PR introduces SQLite support, consider adding test cases for scenarios where Postgres and SQLite behaviors might differ, such as:
- Index types supported by Postgres but not by SQLite
- Different type mappings between the two databases
Would you like assistance in identifying specific edge cases to test?
database/schema/index.go (1)
32-32: Consider adding prefix validation and documentationWhile the prefix concatenation works, consider these improvements:
- Add validation for the prefix format
- Handle cases where the table might already include a prefix
- Document the expected prefix format (e.g., whether it should include the separator)
Example implementation:
func (f *ForeignKeyDefinition) On(table string) schema.ForeignKeyDefinition { + // Skip prefix if table already has it or prefix is empty + if f.prefix == "" || strings.HasPrefix(table, f.prefix) { + f.command.On = table + return f + } f.command.On = f.prefix + table return f }database/schema/grammars/utils.go (2)
36-43: Consider optimizing for single result retrieval.The implementation is correct but creates an unnecessary intermediate slice. Since you only need the first matching command, consider using a direct loop instead.
func getCommandByName(commands []*schema.Command, name string) *schema.Command { - commands = getCommandsByName(commands, name) - if len(commands) == 0 { - return nil - } - - return commands[0] + for _, command := range commands { + if command.Name == name { + return command + } + } + return nil }
45-54: LGTM! Consider adding documentation.The implementation is clean and correct. Consider adding a doc comment to describe the function's purpose and behavior, especially since it's likely to be used by other parts of the SQLite driver implementation.
+// getCommandsByName returns all commands that match the given name. +// Returns an empty slice if no matches are found. func getCommandsByName(commands []*schema.Command, name string) []*schema.Command {database/schema/sqlite_schema.go (3)
10-17: Add documentation for the SqliteSchema struct.Consider adding documentation to describe the purpose and responsibility of this struct. This will help other developers understand its role in the SQLite driver implementation.
+// SqliteSchema handles SQLite-specific schema operations by implementing the Schema interface. +// It uses SQLite-specific grammar and processors for managing database schema operations +// such as creating/dropping tables, managing indexes, and handling views. type SqliteSchema struct {
46-48: Document the purpose of empty implementations.Both
DropAllTypesandGetTypesreturn nil without any implementation. Add comments explaining why these methods are no-ops for SQLite.+// DropAllTypes is a no-op for SQLite as it doesn't support user-defined types func (r *SqliteSchema) DropAllTypes() error { return nil } +// GetTypes returns nil for SQLite as it doesn't support user-defined types func (r *SqliteSchema) GetTypes() ([]schema.Type, error) { return nil, nil }Also applies to: 78-80
67-76: Add error documentation for GetIndexes.The method should document potential error cases to help users handle errors appropriately.
+// GetIndexes retrieves all indexes for the specified table. +// Returns an error if: +// - The database query fails +// - The table doesn't exist func (r *SqliteSchema) GetIndexes(table string) ([]schema.Index, error) {Also, consider validating the table parameter:
func (r *SqliteSchema) GetIndexes(table string) ([]schema.Index, error) { + if table == "" { + return nil, fmt.Errorf("table name cannot be empty") + } table = r.prefix + tabledatabase/schema/grammars/utils_test.go (1)
34-49: The test implementation looks good but could be enhanced.The test covers basic functionality well, with both positive and negative cases.
Consider enhancing the test coverage with these improvements:
func TestGetCommandByName(t *testing.T) { - commands := []*schema.Command{ - {Name: "create"}, - {Name: "update"}, - {Name: "delete"}, - } - - // Test case: Command exists - result := getCommandByName(commands, "update") - assert.NotNil(t, result) - assert.Equal(t, "update", result.Name) - - // Test case: Command does not exist - result = getCommandByName(commands, "drop") - assert.Nil(t, result) + tests := []struct { + name string + commands []*schema.Command + search string + want *schema.Command + }{ + { + name: "command exists", + commands: []*schema.Command{ + {Name: "create"}, + {Name: "update"}, + {Name: "delete"}, + }, + search: "update", + want: &schema.Command{Name: "update"}, + }, + { + name: "command does not exist", + commands: []*schema.Command{ + {Name: "create"}, + {Name: "update"}, + {Name: "delete"}, + }, + search: "drop", + want: nil, + }, + { + name: "empty command slice", + commands: []*schema.Command{}, + search: "update", + want: nil, + }, + { + name: "case sensitive search", + commands: []*schema.Command{ + {Name: "Update"}, + }, + search: "update", + want: nil, + }, + } + + for _, tt := range tests { + t.Run(tt.name, func(t *testing.T) { + got := getCommandByName(tt.commands, tt.search) + if tt.want == nil { + assert.Nil(t, got) + } else { + assert.NotNil(t, got) + assert.Equal(t, tt.want.Name, got.Name) + } + }) + } }This refactoring:
- Uses table-driven tests with subtests for better organization
- Adds test cases for empty command slice and case sensitivity
- Makes the test more maintainable and easier to extend
database/schema/postgres_schema.go (1)
127-132: LGTM! Consider enhancing error handling with context.The refactoring to use
processors.DBIndeximproves code maintainability and standardizes index processing across different database drivers. This change aligns well with the goal of adding SQLite support.Consider wrapping the error with additional context to aid in debugging:
var dbIndexes []processors.DBIndex if err := r.orm.Query().Raw(r.grammar.CompileIndexes(schema, table)).Scan(&dbIndexes); err != nil { - return nil, err + return nil, fmt.Errorf("failed to fetch indexes for table %s.%s: %w", schema, table, err) }database/schema/schema.go (1)
47-48: Consider adding implementation details in TODO comments.While the TODOs indicate future optimizations for MySQL and SQL Server drivers, it would be helpful to add more specific details about what needs to be optimized to guide future implementations.
Consider expanding the TODO comments like this:
- // TODO Optimize here when implementing Mysql driver + // TODO: Implement MySQL-specific schema operations and optimizations: + // - Add support for MySQL-specific column types + // - Implement index handling for MySQL + // - Add support for MySQL-specific table optionsdatabase/schema/grammars/sqlite_test.go (2)
25-40: Consider adding more test cases for TestCompileAdd.While the current test case is valid, consider adding more test cases to cover:
- Different column types (integer, text, blob, etc.)
- Nullable columns
- Columns with different default value types
- Columns without default values
This would ensure comprehensive coverage of the SQLite ALTER TABLE syntax variations.
119-137: Enhance test coverage for default value modifications.Consider adding more test cases to cover:
- Numeric defaults (integer, float)
- Boolean defaults
- Expression defaults (e.g., CURRENT_TIMESTAMP)
- Empty string defaults
- Special characters in string defaults
Example additional test case:
{ name: "with numeric default", setup: func() { mockColumn.EXPECT().GetDefault().Return(42).Twice() }, expectSql: " default 42", },database/schema/grammars/postgres.go (1)
Line range hint
92-106: Consider improving SQL query readability.While the SQL query is functionally correct, its readability could be enhanced by:
- Breaking down the long string concatenation into multiple lines
- Adding comments to explain the purpose of each join
Consider this refactoring:
- return fmt.Sprintf( - "select ic.relname as name, string_agg(a.attname, ',' order by indseq.ord) as columns, "+ - "am.amname as \"type\", i.indisunique as \"unique\", i.indisprimary as \"primary\" "+ - "from pg_index i "+ - "join pg_class tc on tc.oid = i.indrelid "+ - "join pg_namespace tn on tn.oid = tc.relnamespace "+ - "join pg_class ic on ic.oid = i.indexrelid "+ - "join pg_am am on am.oid = ic.relam "+ - "join lateral unnest(i.indkey) with ordinality as indseq(num, ord) on true "+ - "left join pg_attribute a on a.attrelid = i.indrelid and a.attnum = indseq.num "+ - "where tc.relname = %s and tn.nspname = %s "+ - "group by ic.relname, am.amname, i.indisunique, i.indisprimary", - quoteString(table), - quoteString(schema), - ) + query := []string{ + // Select index properties + "select ic.relname as name,", + " string_agg(a.attname, ',' order by indseq.ord) as columns,", + " am.amname as \"type\",", + " i.indisunique as \"unique\",", + " i.indisprimary as \"primary\"", + // Join with system catalogs + "from pg_index i", + "join pg_class tc on tc.oid = i.indrelid -- Join with table class", + "join pg_namespace tn on tn.oid = tc.relnamespace -- Join with schema namespace", + "join pg_class ic on ic.oid = i.indexrelid -- Join with index class", + "join pg_am am on am.oid = ic.relam -- Join with access method", + "join lateral unnest(i.indkey) with ordinality as indseq(num, ord) on true", + "left join pg_attribute a on a.attrelid = i.indrelid and a.attnum = indseq.num", + // Filter and group + "where tc.relname = %s and tn.nspname = %s", + "group by ic.relname, am.amname, i.indisunique, i.indisprimary", + } + + return fmt.Sprintf( + strings.Join(query, "\n"), + quoteString(table), + quoteString(schema), + )database/schema/schema_test.go (1)

89-95: Track TODOs for future implementations.There are several TODO comments for implementing tests for:
- Drop all types
- Drop all views
These should be tracked to ensure they're implemented when the corresponding features are added.
Would you like me to create GitHub issues to track these implementations?
database/schema/grammars/sqlite.go (1)
59-61: Unused parameter 'views' inCompileDropAllViewsThe
viewsparameter is not used inCompileDropAllViews, which may cause confusion or unintended behavior.Consider modifying the method to use the
viewsparameter to generateDROP VIEWstatements for each view:func (r *Sqlite) CompileDropAllViews(views []string) string { - return "delete from sqlite_master where type in ('view')" + var statements []string + for _, view := range views { + statements = append(statements, fmt.Sprintf("drop view if exists \"%s\";", view)) + } + return strings.Join(statements, " ") }

1-9: LGTM! Clean package structure and imports.
The package organization follows Go conventions with proper import grouping.
10-15: Verify consistency with other database processors.
The Sqlite struct is currently empty. Let's verify if this matches the pattern used by other database processors in the codebase.
✅ Verification successful
Let me search for other database processor implementations to verify if the empty Sqlite struct is consistent with the pattern.
Let me try a different approach to find processor implementations using ripgrep.
I can now generate the final response based on the findings.
Empty struct implementation is consistent with other processors
The empty Sqlite struct implementation is consistent with the pattern used by other database processors in the codebase. Both Sqlite and Postgres processors are implemented as empty structs with simple constructors that return empty struct instances.

1-9: LGTM! Clean package structure and imports.
The package name and import organization follow Go best practices.
45-51: LGTM! Good edge case coverage.
The empty input test case properly validates the nil return behavior.
database/schema/processors/postgres_test.go (4)
6-6: LGTM: Good choice switching to testify/assert
The switch to testify/assert is a positive change as it's a more widely adopted and actively maintained testing library in the Go ecosystem.
Line range hint 13-32: Well-structured test cases with improved assertions
The test cases are well-organized with:
- Clear input/expected output pairs
- Explicit handling of empty input case
- Consistent assertion patterns
35-35: LGTM: Consistent function renaming
The renaming to include the "Postgres" prefix maintains consistency with the new naming convention while preserving the comprehensive test coverage.
11-11: Verify impact of DBIndex structure change
The change from schema.Index to DBIndex represents a breaking change in the API. This could affect other parts of the codebase that interact with the index processing functionality.
Also applies to: 13-15
database/schema/index.go (2)
9-9: LGTM: Clean addition of prefix field
The addition of the prefix field to ForeignKeyDefinition is well-structured and follows Go conventions.
12-16: Verify constructor usage across the codebase
The constructor changes look good, but we should verify all callers have been updated with the new prefix parameter.
✅ Verification successful
Constructor update is properly propagated
The verification confirms that there is only one caller of NewForeignKeyDefinition in the codebase, located in database/schema/blueprint.go, and it correctly provides both the command and prefix parameters as required by the updated constructor signature.

Let's verify how these functions are being used in the SQLite driver implementation to ensure they meet the requirements.
✅ Verification successful
Based on the provided context, I can now generate the final response since I have enough information about how these command retrieval functions are being used in the SQLite implementation.
Command retrieval functions are correctly used in SQLite grammar implementation
The functions are used appropriately in the SQLite grammar implementation:
getCommandByNameis used to retrieve primary key commands inCompileCreategetCommandsByNameis used to retrieve foreign key commands inCompileCreate- Both functions are used together to properly construct table creation SQL with primary and foreign key constraints

1-80: Verify SQLite schema operations coverage.
Let's verify if all necessary SQLite schema operations are implemented by checking the codebase for any missing operations.
✅ Verification successful
Let me gather more information about the schema implementations across different drivers to make a proper comparison.
Let me check the driver-specific schema interface and compare implementations across different drivers.
SQLite schema implementation is complete and correct
The SQLite schema implementation correctly implements all required methods from the DriverSchema interface:
DropAllTables(): Properly handles SQLite-specific requirements with enable/disable writable schemaDropAllTypes(): Correctly returns nil as SQLite doesn't support custom typesDropAllViews(): Properly handles view dropping with enable/disable writable schemaGetIndexes(): Correctly retrieves and processes indexesGetTypes(): Correctly returns nil as SQLite doesn't support custom types
The implementation aligns with SQLite's capabilities and limitations, following proper SQLite-specific patterns like enabling/disabling writable schema for structural changes.

52-54: LGTM! SQLite implementation follows the established pattern.
The SQLite driver implementation follows the same pattern as PostgreSQL, properly initializing the grammar and creating the schema with prefix support.
Let's verify the SQLite implementation is complete:
✅ Verification successful
Let me gather more information about the SQLite implementation to verify its completeness.
Let me check the specific method implementations to ensure SQLite has all the necessary functionality.
Let me try one more verification with modified patterns to better detect the implementations.
SQLite implementation is complete and follows the established pattern
The verification confirms that the SQLite implementation is complete and properly structured:
- The grammar implementation (
database/schema/grammars/sqlite.go) includes all necessary methods for SQL operations, data types, and modifiers - The schema implementation (
database/schema/sqlite_schema.go) correctly extends CommonSchema and implements SQLite-specific operations - The processor implementation (
database/schema/processors/sqlite.go) handles SQLite-specific index processing - The initialization pattern in the reviewed code matches the implementation's requirements
The code follows the same pattern as PostgreSQL with proper grammar initialization, schema creation, and prefix support.

Line range hint 12-17: Verify impact of removing GetPrefix method.
The removal of GetPrefix and direct usage of the prefix field improves encapsulation. However, we should verify that this change doesn't impact existing code that might have depended on the public method.
Let's check for potential usage of the removed method:
#!/bin/bash
# Description: Check for potential usage of the removed GetPrefix method
# to ensure no breaking changes.
echo "Checking for potential GetPrefix usage:"
rg "GetPrefix\(\)" --type go
echo "Checking for interface implementations:"
ast-grep --pattern 'type $_ struct {
$$$
}
func ($_ $_) GetPrefix() string {
$$$
}'66-66: LGTM! Verify SQLite foreign key behavior.
The change to pass the table prefix directly to the foreign key definition is a good approach. This will help in correctly constructing foreign key constraints, especially for SQLite which might handle prefixed tables differently.
Let's verify the SQLite-specific foreign key handling:
✅ Verification successful
Based on the gathered information, I can now provide a final response:
The prefix handling in foreign key definitions is correctly implemented
The changes are verified to be correct and well-structured:
- The
ForeignKeyDefinitioninterface incontracts/database/schema/index.godefines the contract - The implementation properly handles the prefix through constructor injection
- SQLite-specific handling is implemented in dedicated files (
database/schema/grammars/sqlite.goanddatabase/schema/processors/sqlite.go) - The
Commandstruct contains all necessary fields for foreign key operations including table references

65-65: Verify the impact of prefix removal in foreign key references.
The direct use of command.On without prefix concatenation aligns with the removal of GetPrefix(), but we should verify that this doesn't break existing foreign key references.
Let's check for any existing foreign key constraints that might be affected:
✅ Verification successful
Based on the search results, I can now generate the final response:
Foreign key reference handling is correctly implemented
The removal of prefix concatenation with command.On is consistent across both PostgreSQL and SQLite implementations:
- PostgreSQL uses
command.Ondirectly in the foreign key SQL generation - SQLite follows the same pattern, using
command.Onwithout prefix manipulation - Test cases in both
postgres_test.goandsqlite_test.govalidate this behavior with proper references to table names

136-139: Verify SQLite primary key behavior.
The code correctly handles SQLite's different behavior with primary keys. Let's verify this limitation in SQLite's documentation.
✅ Verification successful
Let me gather more specific information about SQLite's primary key handling in the codebase.
Based on the code analysis, I can now generate the final response as the implementation clearly shows SQLite's different behavior with primary keys.
SQLite primary key behavior verification confirmed
The code correctly handles SQLite's unique primary key implementation:
- SQLite handles primary keys directly in column definition using
primary key autoincrementfor auto-incrementing columns - Primary keys are defined inline during table creation, not as separate index definitions
- The
CompilePrimarymethod in SQLite grammar returns an empty string, confirming that separate primary key creation is not supported

170-174: Consider testing additional SQLite index types.
While the code correctly handles the basic index type difference between SQLite and PostgreSQL, consider expanding the test coverage to include other SQLite-specific index types (if any).
✅ Verification successful
Let me try a different search strategy to find information about SQLite index types and their implementation.
Let me try one final search to specifically look at SQLite's index implementation and documentation.
Based on the search results, I can now provide a final response:
The empty index type for SQLite is the correct implementation
Looking at the codebase implementation:
- SQLite's
ProcessIndexesmethod indatabase/schema/processors/sqlite.godeliberately omits the index type field - The
CompileIndexmethod indatabase/schema/grammars/sqlite.gocreates indices without specifying a type - SQLite test cases confirm this behavior, showing that index types like "BTREE" and "HASH" are ignored during processing
This aligns with SQLite's documentation where index types are not specified in CREATE INDEX statements, as SQLite automatically determines the most appropriate index implementation internally.

118-118: LGTM! Test cases correctly reflect the prefix handling changes.
The updated test assertions properly align with the architectural changes where table prefixes are now handled at the foreign key definition level rather than through the Blueprint interface.
Let's verify the consistency of these changes with related files:
Also applies to: 128-128
✅ Verification successful
Let me gather more information to verify the consistency across different SQL grammar implementations.
Let me check the SQLite test implementation to ensure consistency across different database drivers.
Foreign key handling is consistent across database implementations
The verification shows that the prefix removal is correctly implemented:
- PostgreSQL handles foreign keys through
CompileForeignmethod with explicit ALTER TABLE statements - SQLite handles foreign keys inline during table creation, as seen in
TestCompileCreate - Both implementations now handle foreign keys without table prefixes, maintaining consistency with the architectural changes

142-144: Ensure correct auto-increment handling in ModifyIncrement
In SQLite, auto-incrementing primary keys require the column to be of type INTEGER and defined as PRIMARY KEY AUTOINCREMENT. Ensure that only one column per table is set as an auto-incrementing primary key.
Run the following script to verify that there is only one auto-incrementing primary key per table:

The slices package was introduced in Go 1.18. Please ensure that the project specifies Go 1.18 or higher to avoid compatibility issues with earlier Go versions.
Run the following script to verify the Go version specified in the project:
✅ Verification successful
The previous script execution seems to have failed to show the go.mod content. Let me try again with a different command to check the Go version.
Go version compatibility verified for slices package usage
The project's go.mod file specifies Go 1.22.7 with toolchain go1.23.3, which is well above the minimum required version (Go 1.18) for using the slices package. The usage of the slices package is compatible with the project's Go version.

25-40: Enhance test coverage with additional scenarios.Consider adding test cases for:
- Different column types (e.g., integer, text, blob)
- Different default value types (e.g., numbers, booleans)
- Column with multiple modifiers
Example test case:
// Test integer column with numeric default mockColumn.EXPECT().GetName().Return("age").Once() mockColumn.EXPECT().GetType().Return("integer").Twice() mockColumn.EXPECT().GetDefault().Return(18).Twice() mockColumn.EXPECT().GetNullable().Return(false).Once()
118-136: Add more test cases for different default value types.The table tests should include additional scenarios:
tests := []struct { name string setup func() expectSql string }{ // ... existing tests ... { name: "with numeric default", setup: func() { mockColumn.EXPECT().GetDefault().Return(42).Twice() }, expectSql: " default 42", }, { name: "with boolean default", setup: func() { mockColumn.EXPECT().GetDefault().Return(true).Twice() }, expectSql: " default true", }, { name: "with expression default", setup: func() { mockColumn.EXPECT().GetDefault().Return("CURRENT_TIMESTAMP").Twice() }, expectSql: " default CURRENT_TIMESTAMP", }, }
