To check if a MySQL table is locked, you can use the following method:

  1. Use the SHOW OPEN TABLES command to check the status of tables. This command will display all currently open tables and their respective statuses. If a table is locked, the status will show as “Locked”.
SHOW OPEN TABLES LIKE 'table_name';
  1. Use the SHOW PROCESSLIST command to check the processes currently running. If a process is locking a table, it will be displayed in the results.
SHOW PROCESSLIST;
  1. Use the INFORMATION_SCHEMA.TABLES system table to query the locking status of a table. This table stores information about tables in the database, including their locking status. Filtering can be done based on table name and database name.
SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = 'table_name' AND TABLE_SCHEMA = 'database_name';

The above method will assist you in determining if a MySQL table is locked.
