MySQL 1187: Statement failed due to SAVEPOINT.

What is MySQL 1187: Statement failed due to SAVEPOINT.

When encountering the error 1187: "Statement failed due to SAVEPOINT" in MySQL, the user should take the following immediate actions:

Identify the Current Transaction State: Check if your session is currently in a transaction that might be causing the issue.

SELECT @@autocommit;

Review the SAVEPOINT(s): Identify the existing savepoints within your transaction to understand their hierarchy and naming.

SHOW VARIABLES LIKE 'maxsprecursion_depth';

Check for Implicit Commit Statements: Identify if there are any implicit commit statements within your transaction block. Statements that cause an implicit commit should be reviewed.

Error Log Review: Check the MySQL error log for any related messages that might give more context about the problem.

tail -n 100 /var/log/mysql/error.log

Transaction Isolation Level: Check the current session's transaction isolation level, as it might influence behavior with savepoints.

SELECT @@tx_isolation;

Rollback to Previous SAVEPOINT: If a specific savepoint name is known and you suspect the error occurred after creating it, try rolling back to that savepoint.

ROLLBACK TO SAVEPOINT savepoint_name;

Release SAVEPOINT if Not Needed: If you have unnecessarily created savepoints, consider releasing them to avoid complexity.

RELEASE SAVEPOINT savepoint_name;

Check Database Engine Status: Ensure that the tables involved in the transaction are using a transactional storage engine like InnoDB.

SHOW TABLE STATUS WHERE Name = 'yourtablename';

Inspect Running Transactions: Look for any long-running or blocked transactions that might be affecting your current session.

SHOW ENGINE INNODB STATUS;

Check for Deadlocks: Deadlocks can sometimes cause unexpected behavior with transactions and savepoints.

SHOW ENGINE INNODB STATUS;These actions aim to directly address the issue or gather necessary information to diagnose and resolve the error related to savepoints in MySQL.
