Drop all schema objects
Be careful when you drop all schema objects safely in Oracle.
DECLARE
v_itemcount INTEGER;
BEGIN
SELECT Count(*)
INTO v_itemcount
FROM all_objects AO
WHERE AO.owner = USER
AND AO.object_type NOT IN ( ‘INDEX’ )
AND AO.object_name NOT LIKE ‘BIN$%’;
WHILE ( v_itemcount > 0 ) LOOP
FOR v_cmd IN (SELECT ‘drop ‘
|| AO.object_type
|| ‘ ‘
|| AO.object_name
|| Decode(AO.object_type, ‘TABLE’,
‘ CASCADE CONSTRAINTS’,
”) AS DROPCMD
FROM all_objects AO
WHERE AO.owner = USER
AND AO.object_type NOT IN ( ‘INDEX’ )
AND AO.object_name NOT LIKE ‘BIN$%’) LOOP
BEGIN
EXECUTE IMMEDIATE v_cmd.dropcmd;
EXCEPTION
WHEN OTHERS THEN
NULL; — ignore errors
END;
END LOOP;
SELECT Count(*)
INTO v_itemcount
FROM all_objects AO
WHERE AO.owner = USER
AND AO.object_type NOT IN ( ‘INDEX’ )
AND AO.object_name NOT LIKE ‘BIN$%’;
END LOOP;
EXECUTE IMMEDIATE ‘purge recyclebin’;
END;
