How delete table inner join with other table in Sqlite?

Question

My query:

DELETE a FROM TR_ContactResultRecord  a
INNER JOIN TR_Case  b on (a.FireStationCode=b.FireStationCode and a.CaseNo=b.CaseCode )
WHERE b.Update_Date         


        

Answer 1

Try to rewrite you query using subquery: In case your PK for TR_ContactResultRecord is CaseNo

DELETE FROM TR_ContactResultRecord
WHERE CaseNo IN (
  SELECT CaseNo FROM TR_ContactResultRecord a
  INNER JOIN TR_Case b
    ON (a.FireStationCode=b.FireStationCode and a.CaseNo=b.CaseCode )
  WHERE b.Update_DateTime <=20140628134416
);
