Folks, I'm having a rough time trying to figure out how to debug a DDL trigger. I'm on Oracle 9.2.0.4, under Tru64 5.1. I've written a trigger whose purpose is to make a backup copy of a table in one schema into another, before the table gets dropped. The problem is, as far as I can tell, the trigger is never fired. I've validated that the trigger exists and is enabled, but can't get any further. Is there a way to trace how triggers get chosen to be fired by Oracle? Here's the trigger's text: CREATE OR REPLACE TRIGGER sys.cp_tab_before_drop_btg BEFORE drop ON dherri.SCHEMA WHEN ( ora_dict_obj_type = 'TABLE' AND ( ora_dict_obj_name LIKE 'SCORE\_ACCT\_TB\_%' ESCAPE '\' ) ) DECLARE PRAGMA AUTONOMOUS_TRANSACTION; v_datestamp DATE := sysdate; v_ddl_stmt VARCHAR2(4000); v_ora_error NUMBER; v_procedure_name VARCHAR2(30) := 'CP_TAB_BEFORE_DROP_BTG'; v_procedure_owner VARCHAR2(30) := 'SYS'; v_table_count PLS_INTEGER := 1; BEGIN INSERT INTO dherri.aud_plsql_error_tb values ('SYS','Test: Before SELECT',1,sysdate); COMMIT; /* * Validate the table to be dropped does exist. */ SELECT COUNT(*) INTO v_table_count FROM dba_tables WHERE owner = ora_dict_obj_owner AND table_name = ora_dict_obj_name; IF v_table_count > 0 THEN INSERT INTO dherri.aud_plsql_error_tb values ('SYS','Test: Within IF-TEST',v_table_count,sysdate); COMMIT; v_ddl_stmt := 'CREATE TABLE dherri.'||ora_dict_obj_name||'_bkp PCTFREE 0 AS SELECT * FROM dherri.'||ora_dict_obj_name||';'; EXECUTE IMMEDIATE v_ddl_stmt; END IF; EXCEPTION WHEN OTHERS THEN v_ora_error := ABS(SQLCODE); INSERT INTO dherri.aud_plsql_error_tb VALUES (v_procedure_owner, v_procedure_name, v_ora_error, sysdate); END; / Dave ------------------------------------- Dave Herring, DBA Acxiom Corporation 3333 Finley Downers Grove, IL 60515 wk: 630.944.4762 <mailto:dherri@xxxxxxxxxx <mailto:dherri@xxxxxxxxxx> > ------------------------------------- ************************************************************************** The information contained in this communication is confidential, is intended only for the use of the recipient named above, and may be legally privileged.
