Re: SQL UPDATE question

[Charles Wilt <charles.wilt@xxxxxxxxx>]

You could combine them....

update myfile
 set clientName = :pgmClientName,
       secondfield =  case clientType
                               when  'A' then :secondFieldvalue
                                else secondField
                             end
 WHERE
   clientType = : pgmClientType;

But not you actually update secondfield every time, it's just when
cleintType <> 'A', you updated secondField with its existing value.

HTH,
Charles
