Important
New database features are no longer connected to engine versions; features are now enabled independently during scheduled update windows, and “major” and “minor” releases no longer exist in Helios. Please visit the release notes to view the latest features available in your database clusters.
COMMIT
On this page
The COMMIT command 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 Helios. -
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.
