MariaDB Error 1192: Active Locks or Transactions
Description
This error indicates that a command cannot be executed because the current session holds locks on tables or has an active, uncommitted transaction. MariaDB prevents certain operations to maintain data integrity and consistency when resources are in use, requiring existing operations to conclude first.
Error Message
Can't execute the given command because you have active locked tables or an active transaction
Known Causes
3 known causesExplicit Table Locks
The current session has previously executed a `LOCK TABLES` statement, which prevents other DDL or DML operations until the tables are explicitly unlocked.
Uncommitted Transaction
There is an active transaction in the current session that has not yet been committed (`COMMIT`) or rolled back (`ROLLBACK`), blocking certain subsequent commands.
Implicit Locks from Operations
Certain DDL (Data Definition Language) or DML (Data Manipulation Language) statements can implicitly acquire locks that temporarily prevent other commands from executing.
