SQL UPDATE statement with WHERE EXISTS

Question

Im trying to write a query that updates a date only if the group im updating has a LINE_CD of 50. Would i do it like this?

UPDATE EMPLOYER_ADDL  
SET EMPLOYER_A         


        

Answer 1

I believe this will give you same result.

UPDATE ea
  SET GTL_UW_APPRV_DT = DNTL_UW_APPRV_DT
  FROM EMPLOYER_ADDL AS ea
  INNER JOIN EMP_PLAN_LINE_INFO AS ep
      ON ep.GR_NBR = ea.GR_NBR
      AND ep.LINE_CD = 50
