Transaction

Represents a database transaction

Construction

Transactions are created in the following methods and events:

• Dexie.transaction()
• Dexie.on.populate
• Version.upgrade()

The currently executing transaction is retrieved from Dexie.currentTransaction property.

Properties

active : Boolean

True if transaction has not been committed or aborted yet. Otherwise false.

mode : String

"readonly" or "readwrite"

storeNames : Array

Array of object store names that the Transaction can access. The list depends on which tables were given to Dexie.transaction() when starting the transaction. For upgrade transactions, all object stores will be present in this list.

abort()

Abort the transaction.

table()

Get a Table or WriteableTable instance representing one of your object stores specified in Dexie.version. Table is returned if the transaction was opened in "r" (readonly) mode. WriteableTable will be returned if the transaction was opened in "rw" (readwrite) mode. If transaction is a versionchange transaction (happens only in your registered upgraders and callbacks to on("populate"), the returned instance will be WriteableTable.
