DROP PROCEDURE

Warning

SingleStore 9.0 gives you the opportunity to preview, evaluate, and provide feedback on new and upcoming features prior to their general availability. In the interim, SingleStore 8.9 is recommended for production workloads, which can later be upgraded to SingleStore 9.0.

Syntax

DROP PROCEDURE [IF EXISTS] { procedure_name | database_name.procedure_name }

Remarks

Only one stored procedure can be removed using the DROP PROCEDURE command.
If DROP PROCEDURE is executed for a procedure that does not exist, the following error will occur:
SQL
```
DROP PROCEDURE myprocedure;
```
```
ERROR 1998 (HY000): Function 'db1.myprocedure' doesn't exist
```

However, if the IF EXISTS condition is used and the procedure does not exist, no error will occur:
SQL
```
DROP PROCEDURE IF EXISTS myprocedure;
```
```
Query OK, 0 rows affected (0.00 sec)
```

This command causes implicit commits. Refer to COMMIT for more information.
Refer to the Permission Matrix for the required permission.
