This part of the data type can be used without specifying a metadata file.
-
Numerical type supports most standard SQL numeric data types. These types include strict numeric data types ( int, integer, smallint, decimal, and numeric), as well as approximate numeric data types (float, real, and double, precision).
-
Date and time type The date and time types that represent time values are datetime, date, timestamp, time, and year.
-
String type String types refer to char, varchar, binary, varbinary, blob, text, enum, and set. This section describes how these types work and how to use them in queries.
| Type name | description | Defaults | note |
|---|---|---|---|
| M,D, negative, min, max) | M specifies the total number of data bits, D specifies the number of decimal places, negative specifies positive 1 negative 0, min,max is the min and max value and must be integer | None | Decimal (4, 2, 1, 70, 90) specifies a 4-digit, 2-digit fractional positive floating point number, such as 78.23 |
| string(min, max) | Min, max specifies the range of string digits | None | |
| date(start, end) | Start, end specifies the date range | None | Such as date (1990-01-01, 2019-12-12) |
mark: variable name
start: start value, default value is 1
step: increment step，default value is 1
inc(id) means that the column ID will grow by 1 every time starting from 1. It can be used for MySQL's auto increase primary key
inc(score, 100, 2), means that the column score increase by 2 from 100
The enum type means randomly picking an object randomly from the list, for example: enum(2, 4, 5, 18) means that one of the four integers 2, 4, 5, 8 is randomly selected each time.If there is only one object in the enum array, it means that the data list is read from the file, one object per line: enum(file://data.txt) means to read the list from the data.txt file in the current directory.
The enum type can be used to construct multi-table associations. For example, some fields of two tables use the same enum data list to generate data.
Usage same as enum type.
The difference is that it is used to generate enumeration values in cyclic order. It is often used to generate values in associated multiple columns. For example, one column is city code and the other column is city name. The city code needs to correspond to the city name one by one. The number of enumeration values should be the same for the associated multiple columns.
Note: due to multithreading, it is not guaranteed that the sequence is generated in strict accordance with the enumeration value list. But it can ensure that multiple related columns correspond one by one

The op type indicates that values are calculated from other columns, such as:Op (C0 + C3) means the first column value plus the fourth column value
Op (C1 * C4 + C13) means the value of the first column multiplied by the value of the fifth column plus the value of the fourteenth column

| random_digit | 0~9 random number | 1 | |
| random_digit_not_null | 1~9 random number | 9 | |
| random_element | Random letter | a | |
| random_int | Random number | 44 | The range can be set, which can be set by setting min, max. The default is 0~9999, for example, random_int(1,100) |
| random_letter | Random letter | e | |
| random_number | Random number | For example, random_number(2) generates 2 as a number | |
| boolean | True/False | False | |
| numerify | Three random numbers | 934 | |
| number | A certain number | 44322 | number(digits=None, fix_len=0, positive=0)有三个参数，digits表示多少位数字，fix_len表示是否固定长度（1表示固定长度，否则为1到digits长度）positive表示是否为正数（1为正数，-1为负数，0正负都可能）。number(18, 1, 1) 产生18位数固定长度的正整数 Number (digits = none, fix? Len = 0, position = 0) has three parameters. Digits indicates the number of digits, fix? Len indicates whether the length is fixed (1 indicates fixed length, otherwise 1 to digits length). Position indicates whether the length is positive (1 is positive, - 1 is negative, 0 can be positive or negative). Number (18, 1, 1) produces a positive integer with a fixed length of 18 digits |
