COMMITΒΆ
Commits an open transaction in the current session.

SyntaxΒΆ
COMMIT [ WORK ]
ParametersΒΆ
WORK
Optional keyword that provides compatibility with other database systems.
Usage NotesΒΆ
If two
COMMIT
statements in a row are executed (within the same scope), the second one is ignored. For example, in the following code, the second COMMIT has no effect; there is no open transaction to commit.begin; insert into table1 ...; commit; commit; -- Ignored!
The rules can be more complex if you are using autonomous scoped transactions and stored procedures .
ExamplesΒΆ
Begin a transaction, insert some values into a table, and then complete the transaction by committing it:
SELECT COUNT(*) FROM A1; ----------+ COUNT(*) | ----------+ 0 | ----------+ BEGIN NAME T3; SELECT CURRENT_TRANSACTION(); -----------------------+ CURRENT_TRANSACTION() | -----------------------+ 1432071497832 | -----------------------+ INSERT INTO A1 VALUES (1), (2); -------------------------+ number of rows inserted | -------------------------+ 2 | -------------------------+ COMMIT; SELECT CURRENT_TRANSACTION(); -----------------------+ CURRENT_TRANSACTION() | -----------------------+ [NULL] | -----------------------+ SELECT LAST_TRANSACTION(); --------------------+ LAST_TRANSACTION() | --------------------+ 1432071497832 | --------------------+ SELECT COUNT(*) FROM A1; ----------+ COUNT(*) | ----------+ 2 | ----------+
