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

Try with this also. I think this is new for you ?

UPDATE ADDL   
SET ADDL.GTL_UW_APPRV_DT = ADDL.DNTL_UW_APPRV_DT 
From EMPLOYER_ADDL ADDL
Inner Join  EMP_PLAN_LINE_INFO INFO on INFO.GR_NBR = ADDL.GR_NBR
Where INFO.LINE_CD = 50
