Oracle : How to drop procedures matched by the name mask - oracle

Question

I have created two procedures like :
CREATE OR REPLACE procedure PARTNER_OWNER.test_1
as begin
dbms_output.put_line('Hello World 1 !');
end;
and
CREATE OR REPLACE procedure PARTNER_OWNER.test_2
as begin
dbms_output.put_line('Hello World 2 !');
end;
Now I need to drop the procedures at the same time (something like ):
drop procedure PARTNER_OWNER.test_*;
Is there a way to do that?

Answer 1

I would use a select statement to generate the drop statements and then run them.
select 'DROP PROCEDURE PARTNER_OWNER.'||object_name||';'
from dba_objects
where object_name like 'TEST_%' and
owner = 'PARTNER_OWNER';

One option is to use dynamic SQL. Here's an example:
SQL> create or replace procedure test_1
2 as begin
3 dbms_output.put_line('Hello World 1 !');
4 end;
5 /
Procedure created.
SQL> create or replace procedure test_2
2 as begin
3 dbms_output.put_line('Hello World 2 !');
4 end;
5 /
Procedure created.
SQL> exec test_1;
Hello World 1 !
PL/SQL procedure successfully completed.
SQL> exec test_2;
Hello World 2 !
PL/SQL procedure successfully completed.
Now, drop them:
SQL> begin
2 for cur_r in (select object_name from user_objects
3 where object_type = 'PROCEDURE'
4 and object_name like 'TEST%')
5 loop
6 execute immediate 'drop procedure ' || cur_r.object_name;
7 end loop;
8 end;
9 /
PL/SQL procedure successfully completed.
The result:
SQL> exec test_1;
BEGIN test_1; END;
*
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00201: identifier 'TEST_1' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
SQL> exec test_2;
BEGIN test_2; END;
*
ERROR at line 1:

Alternatively, instead of using an anonymous PL/SQL block, you can rewrite it to a procedure and reuse it later. As it accepts a parameter, you can drop any procedure. Pay attention to LIKE (so that you wouldn't drop a procedure you didn't really want to).
SQL> create or replace procedure p_drop_prc(par_procedure_name in varchar2)
2 is
3 begin
4 for cur_r in (select object_name from user_objects
5 where `enter code here`object_type = 'PROCEDURE'
6 and object_name like upper(par_procedure_name) ||'%')
7 loop
8 execute immediate 'drop procedure ' || cur_r.object_name;
9 end loop;
10 end;
11 /
Procedure created.
SQL> exec p_drop_prc('test');
PL/SQL procedure successfully completed.
SQL> exec test_1;
BEGIN test_1; END;
*
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00201: identifier 'TEST_1' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

Also, you could add another parameter - object type - so that you could drop any object, not just a procedure.
Obviously, quite a few options; pick the one you find the most appropriate.
