i'll try brief. i have single table need data from, contacts. there company field , can in either company or company b. all contacts in company b have duplicate in company a, can matched column legacyid . what i'm trying company rows not have in company b same legacyid . i've tried and legacyid not in (select legacyid contacts company = 'b') and not exists (select legacyid contacts company = 'b') . neither of above work because there 260,000 company contacts , 96,000 company b. not in , not exists worked when there less 50,000 rows total, data migration, query timing out or running forever. thanks if understand correctly, not exists should want: select c.* contacts c companyid = 'a' , not exists (select 1 contacts c2 c2.legacyid = c.legacyid , c2.companyid = 'b' ); for performance, want index on contacts(legacyid, companyid) .
