SingleStore DB

COMMIT

Commits the open transaction if one exists.

Syntax
COMMIT [ WORK ] [ AND [ NO ] CHAIN ] [ [ NO ] RELEASE ]
Remarks
  • [ AND [ NO ] CHAIN ] and [ [ NO ] RELEASE ] are ignored as these options are not currently supported by SingleStore DB.

  • This command must be run on the master aggregator or a child aggregator node (see Node Requirements for SingleStore DB Commands. Note that you must connect to the master aggregator when running this command on reference tables.

  • If the transaction is unsuccessful or needs to be reverted, then execute the ROLLBACK command.

Example

For this example, consider the following Employee table:

ID

Name

30

Jimmy

20

Rob

40

Rick

BEGIN;
UPDATE Employee SET Name = "Jim" WHERE ID = 30;

Run the SELECT query to verify if the UPDATE is correct:

SELECT * FROM Employee;
****
+------+-------+
| ID   | Name  |
+------+-------+
|   30 | Jim   |
|   20 | Rob   |
|   40 | Rick  |
+------+-------+

Run COMMIT since the UPDATE was successful.

COMMIT;

Note: Before the user runs COMMIT or ROLLBACK, only that user can see the updates made after the BEGIN statement was run.
