2. Syntax
The syntax for the AUTOCOMMIT function in H2 database is as follows:
AUTOCOMMIT()
Arguments
- This function does not take any arguments.
Return
- The AUTOCOMMIT function returns a boolean value indicating whether auto-commit mode is enabled (
TRUE
) or disabled (FALSE

3. Notes
- The auto-commit mode determines whether each SQL statement executed in a transaction is committed immediately or not. When auto-commit is enabled, each statement is committed automatically. When disabled, you need to explicitly commit the transaction using the

statement. - By default, the auto-commit mode is enabled in H2 database.
- The AUTOCOMMIT function only provides information about the auto-commit mode for the current connection. It does not modify the auto-commit mode.
- It is important to understand the implications of enabling or disabling auto-commit mode, as it affects the behavior of your database operations.
