Need to test on a field to determine the value that is displayed in a result set. Can I do that in the SELECT statement?
select memb.acct, memb.transamt, memb.name if memb.transactioncode < 100 then memb.transamt = '0' else memb.transactioncode = '100'
I realise that the syntax is not correct, but this is what I am trying to accomplish.
SQL includes the CASE statement, a powerful conditional structure in the SELECT list; however, not all databases support this yet.
I think there's a small error in your question; you are setting the transaction amount to 0 when the transaction code is less than 100, otherwise you are setting the transaction code to 100. I'm going to change this slightly just to illustrate the syntax --
select memb.acct , CASE WHEN memb.transactioncode < 100 THEN 0 ELSE 100 END as transamt , memb.name from memb
See also this previous answer for an example of conditional logic using the Microsoft Access Iif function.
