I have a query like
UPDATE PRD_PRODUCT_L10N ppl
SET ( CATCHING_PHRASE
, GENERIC_NAME
, INGREDIENTS
, QUANTITY
, DOSE
, NUTRITION_FACTS
, PRODUCT_DESCRIPTION
, PROMOTION_MESSAGE
, MESSAGE
) = (
SELECT distinct CATCHING_PHRASE
, GENERIC_NAME
, INGREDIENTS
, QUANTITY
, DOSE
, NUTRITION_FACTS
, PRODUCT_DESCRIPTION
, PROMOTION_MESSAGE
, MESSAGE
FROM TEMP_UPLOAD_PRODUCT_ATTRIBUTES tupa
INNER JOIN
PRD_PRODUCT pp
ON pp .EISIDENTIFIER = tupa.EISIDENTIFIER
WHERE ppl.PRODUCTGUID = pp.GUID
AND ppl.LOCALEGUID = tupa.LOCALEGUID
)
WHERE EXISTS (
SELECT 0
FROM TEMP_UPLOAD_PRODUCT_ATTRIBUTES tupa
INNER JOIN
PRD_PRODUCT pp
ON pp .EISIDENTIFIER = tupa.EISIDENTIFIER
WHERE ppl.PRODUCTGUID = pp .GUID
AND ppl.LOCALEGUID = tupa.LOCALEGUID
)
the subquery returns more than 1 row and I would like to insert the first selected. How do I do that in DB2 database?
Please advice.
Thanks
Depending on your DB2 version (i think 8 upwards) you can use fetch at your subquery
(select * from table fetch first 1 rows only)
