Update columns based on different criteria using merge statement - tsql

Question

So I am using the following merge statement to do an update and insert in one of my tables, however I would like to update another column in the Target table in addition to the one already in the statement. I'm just not sure if I can do that or how to go about it. What I want to do is add in something like
when MATCHED and Source.EventType='Change' Then UPDATE SET Target.DEDCAMT_1 = Source.EmpDedAmt
Can I do that in the same Merge statement?
MERGE dbo.BENTBL as Target
using dbo.BenPaycdUpdate as Source
ON Source.EmpID = Target.EMPLOYID AND Source.Paycode = Target.DEDUCTON
WHEN MATCHED AND source.EventType='Stop'
THEN UPDATE
SET INACTIVE = '1',
Target.DEDENDDT = Source.AsOfDate
WHEN NOT MATCHED BY Target
AND Source.PayCode <> 'FSAH'
THEN INSERT (EMPLOYID, DEDUCTON, INACTIVE, DEDBEGDT, DEDCAMNT_1)
VALUES (Source.EmpID, Source.Paycode,'0', Source.AsofDate,
CAST(REPLACE (REPLACE(ISNULL(source.EmpDed,0),',',''),'$','') AS numeric(19,5)));

Answer 1

You can move the condition from the merge to a case expression, like this:
MERGE dbo.BENTBL as Target
using dbo.BenPaycdUpdate as Source
ON Source.EmpID = Target.EMPLOYID AND Source.Paycode = Target.DEDUCTON
WHEN MATCHED THEN
UPDATE
SET INACTIVE = CASE WHEN source.EventType = 'Stop' THEN '1' ELSE INACTIVE END,
Target.DEDCAMT_1 = CASE WHEN source.EventType = 'Change' THEN Source.EmpDedAmt ELSE Target.DEDCAMT_1 END,
Target.DEDENDDT = Source.AsOfDate
WHEN NOT MATCHED BY Target AND Source.PayCode <> 'FSAH' THEN
INSERT (EMPLOYID, DEDUCTON, INACTIVE, DEDBEGDT, DEDCAMNT_1)
VALUES (Source.EmpID, Source.Paycode,'0', Source.AsofDate,
CAST(REPLACE (REPLACE(ISNULL(source.EmpDed,0),',',''),'$','') AS numeric(19,5)));
