COMMIT

Name

COMMIT -- Ends the current transaction block and finalizes changes made within it.

Synopsis

COMMIT [ WORK | TRANSACTION ]

Parameters

WORK | TRANSACTION

A pair of optional noise keywords. They can be ignored, or used to make your SQL more readable.

Results

COMMIT

The message returned when the current transaction is successfully committed.

NOTICE: COMMIT: no transaction in progress

The notice returned if there is no current transaction for the COMMIT command to actually commit.

Description

Use the COMMIT command to finalize the current transaction. Once a COMMIT is performed, any modifications made by the transaction are saved into the database.

Note: If something unintended happens during a transaction block, you can use the ROLLBACK command to abort the current transaction. This undoes the effect of any SQL executed after the last BEGIN statement.

Examples

The following example begins a transaction, modifies data, and then commits the modifications:

booktown=# 
BEGIN WORK;

BEGIN
booktown=# 
INSERT INTO employees VALUES (106, 'Hall', 'Timothy');

INSERT 3574402 1
booktown=# 
COMMIT WORK;
