Procedures are defined using PL/SQL. Refer to Oracle Database PL/SQL Language Reference for complete information on creating, altering, and dropping procedures.

Use the DROP PROCEDURE statement to remove a standalone stored procedure from the database. Do not use this statement to remove a procedure that is part of a package. Instead, either drop the entire package using the DROP PACKAGE statement, or redefine the package without the procedure using the CREATE PACKAGE statement with the OR REPLACE clause.


The procedure must be in your own schema or you must have the DROP ANY PROCEDURE system privilege.




Specify the schema containing the procedure. If you omit schema, then Oracle Database assumes the procedure is in your own schema.


Specify the name of the procedure to be dropped.

When you drop a procedure, Oracle Database invalidates any local objects that depend upon the dropped procedure. If you subsequently reference one of these objects, then the database tries to recompile the object and returns an error message if you have not re-created the dropped procedure.


Dropping a Procedure: Example

The following statement drops the procedure remove_emp owned by the user hr and invalidates all objects that depend upon remove_emp:

DROP PROCEDURE hr.remove_emp;
