Question
UPDATE statement syntax help
Experts,
This query is taking way to long....I mean way to long...what is wrong with it?
UPDATE MyTable tabA
SET PROV_REPGRPID = (SELECT DISTINCT REPGRPID_PROV
FROM DR_SPECIALTY tabB
WHERE tabA.PROVIDER_ID = tabB.BRIDGE_SERV_PROV)
where exists(select 1 from tabB PROV where m.PROVIDER_ID = prov.BRIDGE_SERV_PROV )
Not hard for you I'm sure...just very very urgent for me. Both fields in the "WHERE" clause are indexed and tabA has about 800K records and tabB has about 125K.
