PLS-00405: subquery not allowed in this context

[M.Shakeel Azeem]

Dear All,

i am trying to create the following trigger but got the error "PLS-00405: subquery not allowed in this context"
can anybody help me in this regard?

CREATE OR REPLACE TRIGGER trg_sdr_tblsswcdrs
BEFORE INSERT
ON terminusbill.sdr_tblsswcdrs
FOR EACH ROW
DECLARE
elementid NUMBER (10):= 2;
BEGIN

IF :NEW.ssw_duration > 0
AND :NEW.SSW_IC_CarrierID) Not IN (SELECT UPPER(TRUNKID) FROM NE_TRUNKSFORSUBREPORTS )


THEN
INSERT INTO sdr_tblsubmissedcdrs
(smcr_rawcdrid, pc_parsedcode, pe_errorcode,
smcr_callingnumber, smcr_callednumber, ne_elementid,
smcr_calltime, ct_calltypeid, smcr_voiceusageduration
)
VALUES (:NEW.ssw_voicerecordid, 0, 0,
:NEW.ssw_txcallingnum, :NEW.ssw_txcallednum, 2,
:NEW.ssw_disconntime, 0, CEIL (:NEW.ssw_duration / 10)
);
END IF;
END IF;

Subqueries are only allowed in SQL statements which is not your case -IF

You may want to rewrite your trigger in a way your IF statement is asking for a condition set in between BEGIN and IF statements.
