proc SQL update table with CASE when

Hi SAS users,

 

I need help with writing this SQL correctly. I need to update/alter a table with status of 'SUCCESS/FAILURE'  based on the case condition .

 

UPDATE &SUM_TABLE A
SET
STAT = 'SUCCESS'      

             case WHEN ((B.INPUT_CNT - A.UNIQUE_CLAIM_ID)=0
                                     (SELECT COUNT(*) AS INPUT_CNT

                                                        FROM MANUAL_TEMP B)

                                       )
ELSE 'FAILURE'
END;

 

Thanks,

Ana

Re: proc SQL update table with CASE when

Proper syntax would be:

 

UPDATE &SUM_TABLE
SET
	STAT = case 
		when UNIQUE_CLAIM_ID = (SELECT COUNT(*) FROM MANUAL_TEMP)
			then 'SUCCESS'
			else 'FAILURE'
			end;

but I doubt that this is what you really want to do. I doesn't look right to equate a claim ID with the record count in another table. Could you explain what the SUCCESS/FAILURE condition is supposed to be?
