Trigger returning different date formats.

Question

Posted from Windows forum:
We just reticently received a update to an .net application from a vendor. When our client machines (Windows XP) run the app we receive 2 different date formats returned from an post insert table trigger. The correct format is 'DD-MON-YY' in which a couple machines still return and the others return the format 'YYYY-MM-DD HH24:MM:SS'. I've tried setting the NLS_Date Format with no success. Database is Oracle 8i. Any suggestions?

Answer 1

CREATE TABLE X.ACCESS_LOG
ACCESS_LOG_ID NUMBER NOT NULL,
SYS_ID NUMBER NOT NULL,
DATE_IN DATE NOT NULL,
DATE_OUT DATE NOT NULL,
INSTRUMENT_ID_IN NUMBER,
INSTRUMENT_ID_OUT NUMBER,
STATION_IN VARCHAR2(20),
STATION_OUT VARCHAR2(20),
AREA_IN VARCHAR2(25),
AREA_OUT VARCHAR2(25)
CREATE OR REPLACE TRIGGER XFER_TO_TRACKING
AFTER INSERT
ON x.ACCESS_LOG
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
DECLARE
     v_qtr Number;
BEGIN
SELECT qtr
INTO v_Qtr
FROM X.QTR_SET
WHERE to_date(:new.Date_In,'dd-mon-yy') BETWEEN first_date AND last_date;
Insert (....)
END/
Here is the basic code for table and trigger. When the trigger fires the value for :new.date_in will come over in the format of "dd-mon-yy", which we have been looking for, or "YYYY-MM-DD HH24:MM:SS" which just came up with this new release depending on which station is used.
