Could someone please tell me what I'm doing wrong please. I have tried it so many ways.
I just want to update one column based on the value held in another column.
Here's what I've tried, or one of the ways I've tried.

UPDATE    Customers
SET CustTypeDescription = CASE
WHEN (CustType = 2) THEN CustTypeDescription = 'Other Retail'
WHEN (CustType = 4) THEN CustTypeDescription = 'Convenience Store'

and this

UPDATE    Customers
SET CustTypeDescription = CustTypeDescription
WHEN CustType = 2 THEN CustTypeDescription = 'Other Retail'
WHEN CustType = 4 THEN CustTypeDescription = 'Convenience Store'

thanks for the help...
