Hi Oracle Gurus,
Please help me, in finding what is wrong in trigger statement. It doesn not create trigger, instead it displays line numbers..like 1 2 3 4 ....after pressing the enter key,
I am attaching the full script, where it alters table, then creates new table, the creates sequence..lastly it fails in creating the trigger.

Ok great..but it gives the same error, we have already checked that AUDIT_LOG does exist.
Is it checking something else..or it shoud be INSERT INTO instead of INSERT ON.
Please help.
create or replace
TRIGGER "MOBILE"."AUDIT_LOG_TRGR" before
INSERT ON "AUDIT_LOG" FOR EACH row BEGIN IF inserting THEN IF :NEW."AUDIT_LOG_ID" IS NULL THEN
SELECT AUDIT_LOG_SEQ.nextval
INTO :NEW."AUDIT_LOG_ID"
FROM dual;
END IF;
END IF;
END; /
INSERT ON "AUDIT_LOG" FOR EACH row BEGIN IF inserting THEN IF :NEW."AUDIT_LOG_ID" IS NULL THEN
ERROR at line 3:
ORA-00942: table or view does not exist
