CREATE OR REPLACE TRIGGER UPDATE_TEST_280510
AFTER insert on TEST_TRNCOMPVISIT
declare
V_TRNCOMPNO NUMBER(10);
CURSOR C1 IS SELECT B.COMPNO FROM TEST_TRNCOMPVISIT A, TEST_TRNCOMPMST B, TEST_MEMMAST C
WHERE A.COMPNO=B.COMPNO
AND B.TRNMEMID=C.MEMID
AND C.MEMOS=1000;
begin
open c1;
fetch c1 into V_TRNCOMPNO;
UPDATE TEST_TRNCOMPMST SET COMPSTATUS='P', remark='comp is pending due to O/S1000'
WHERE COMPNO=V_TRNCOMPNO AND COMPSTATUS='C';
CLOSE C1;
end;
I have made this trigger and while insert the row in table- TEST_TRNCOMPVISIT it gives following error-
The following error has occurred:
ORA-04091: table TEST.TEST_TRNCOMPVISIT is mutating, trigger/function may not see it
