@@SESSION.GTID_NEXT cannot be changed by a client that
MySQL raises error 1790 (SQLSTATE HY000) with the message "@@SESSION.GTID_NEXT cannot be changed by a client that owns a GTID" when a session attempts to run SET @@SESSION.GTID_NEXT while it still owns an uncommitted GTID.
GTIDs uniquely tag each transaction for replication. A session that holds a GTID cannot request a new one until it commits or rolls back. This safeguard prevents duplicate or out-of-order GTIDs that could corrupt replication.
The error appears during manual GTID management, usually in advanced replication setups or schema migrations, when developers switch GTID_NEXT from AUTOMATIC to a specific value mid-transaction.
It also occurs in stored procedures or scripts that interleave explicit SET @@SESSION.GTID_NEXT statements with transaction control but forget to release the previous GTID.
Finish or abandon the current transaction before changing @@SESSION.GTID_NEXT. Use COMMIT to make changes permanent or ROLLBACK to discard them. Once ownership ends, reset GTID_NEXT to AUTOMATIC or any desired value.
If you do not need manual GTID assignment, leave @@SESSION.GTID_NEXT set to AUTOMATIC for the entire session to avoid the error completely.
During logical backup imports, switch GTID_NEXT to UUID:NUMBER only between transactions. Use AUTOCOMMIT=1 or INSERT … COMMIT blocks to release GTIDs quickly.
When applying binlog events manually, wrap each event in START TRANSACTION; SET @@SESSION.GTID_NEXT=…; COMMIT; to ensure ownership never overlaps.
Automate GTID assignment by keeping @@SESSION.GTID_NEXT set to AUTOMATIC. Only override it in controlled maintenance scripts.
Insert explicit COMMIT or ROLLBACK statements after every manual GTID transaction. Add unit tests that check for pending transactions before changing GTID_NEXT.
Errors 1788 (ER_CANT_SET_GTID_NEXT_TO_GTID_WHEN_GTID_MODE_IS_OFF) and 1789 (ER_CANT_SET_GTID_NEXT_TO_ANONYMOUS_WHEN_GTID_MODE_IS_ON) also involve incorrect GTID_NEXT usage. Fix them by aligning GTID mode and transaction context.
A session started a transaction, owns a GTID, and tries to set GTID_NEXT before committing.
Error-handling code exits early without rolling back, leaving the GTID owned.
Scripts that cycle GTID_NEXT for replaying binlog events omit a COMMIT between events.
SET autocommit=0 keeps transactions open longer than expected, causing overlapping GTID ownership.
Raised when you set GTID_NEXT to a specific value while GTID_MODE=OFF. Turn GTID mode ON or revert to AUTOMATIC.
Appears when setting GTID_NEXT='ANONYMOUS' while GTID_MODE=ON. Use a valid UUID:NUMBER pair or switch GTID mode.
Indicates unsafe statements executed with autocommit=1 under GTID replication. Rewrite statements or disable GTID.
No. The server enforces GTID integrity. Always release the current GTID before requesting a new one.
Yes. With autocommit=1 each statement commits immediately, so the session rarely owns a GTID when you change GTID_NEXT.
The error exists in MySQL 5.6 and later, when GTID replication was introduced.
Galaxy flags long-running transactions and inserts the required COMMIT or ROLLBACK snippets, reducing GTID errors.
