Dropping objects without ORA-00942 errors
This procedure enables to drop any object in an Oracle database if you have the rights for it. It will give you a clean spool file -- no ORA-00942 messages -- when installing or dropping objects where you are not sure if they exist or not. This produces no error messages even if the object does not exist. It may be useful when looking for any other errors in big spool files after installing hundreds of tables, views, packages, etc. The script has been tested on v. 8.1.7.
create or replace procedure dropObject (ownerName in varchar2, objectName in varchar2) is
cursor C1 is
select 'DROP '||o.object_type||' "' || o.owner || '"."' || o.object_name ||'"'
from sys.dba_objects o
where o.owner = ownerName
and o.object_name = objectName ;
DDL_CURSOR := dbms_sql.open_cursor;
FETCH C1 INTO ddl_statement;
EXIT WHEN C1%NOTFOUND;
dbms_sql.parse(DDL_CURSOR, ddl_statement, dbms_sql.native);
