Update Query Updating All Records - Only Want Select Records Updated
UPDATE: I am using a query from a response below. When running this query, it is clearing the SERVICE_DATE_OUT field if it does not find a match with the where conditions. Is there a work around for this?
UPDATE PMEQMT P
SET SERVICE_DATE_OUT = (SELECT MAX(TL.TRANS_DATE)
FROM TRANSLOG TL
WHERE P.EQNO = TL.ITEMNO AND
TL.LOC_DESC = 'E-OUT OF SERVICE' AND
TL.TRANS_DATE >= SYSDATE - 1
)
WHERE P.CLASS = 'TL'
What I am trying to accomplish here is that when an ITEMNO on the TRANSLOG table is in an E-OUT OF SERVICE/E-IN SERVICE location and matches PMEQMT.EQNO then update the SERVICE_DATE_OUT/IN for that respective PMEQMT.EQNO.
The queries are updating SERVICE_DATE_OUT/IN for all records in the PMEQMT table. Can someone help me modify my queries to update only the matched PMEQMT.EQNO to TRANSLOG.ITEMNO?
UPDATE PMEQMT
SET SERVICE_DATE_OUT = (SELECT B.TRANS_DATE
FROM TRANSLOG B, PMEQMT A
WHERE A.EQNO = B.ITEMNO AND
A.CLASS = 'TL' AND
B.LOC_DESC = 'E-OUT OF SERVICE' AND
B.TRANS_DATE >= SYSDATE - 1)
UPDATE PMEQMT
SET SERVICE_DATE_IN = (SELECT B.TRANS_DATE
FROM TRANSLOG B, PMEQMT A
WHERE A.EQNO = B.ITEMNO AND
A.CLASS = 'TL' AND
B.LOC_DESC = 'E-IN SERVICE' AND
B.TRANS_DATE >= SYSDATE - 1)

I think you just want a correlated subquery:
UPDATE PMEQMT p
SET SERVICE_DATE_OUT = (SELECT tl.TRANS_DATE
FROM TRANSLOG tl
WHERE p.EQNO = tl.ITEMNO AND
p.CLASS = 'TL' AND
tl.LOC_DESC = 'E-OUT OF SERVICE' AND
tl.TRANS_DATE >= SYSDATE - 1
);
I don't think the logic quite right -- the subquery is filtering on the outer table and it could return more than one row. If I were to speculate, this is closer to what you want:
UPDATE PMEQMT p
SET SERVICE_DATE_OUT = (SELECT MIN(tl.TRANS_DATE)
FROM TRANSLOG tl
WHERE p.EQNO = tl.ITEMNO
tl.LOC_DESC = 'E-OUT OF SERVICE' AND
tl.TRANS_DATE >= SYSDATE - 1
)
WHERE p.CLASS = 'TL';

Gordon, that was going to be my next question. I am running into it returning more than one row. When testing the lower query I am receiving the error: FROM keyword not found where expected Any ideas?
