Question

My code is as follows:

REPLACE(REPLACE(cc.contype,'x','y'),'y','z') as ContractType,

This REPLACE’s correctly what I would like, but it unfortunatley changes all “z’s” to “y’s” when I would like

x > y
y > z

Does this make sense? I would not like all of the new Y’s to then change again in my second REPLACE function. In Microsoft Access, I would do this with the following

Iif(cc.contype = x, y, iif(cc.contype = y, x))

But I am not sure how to articulate this in SQL, would it be best I do this kind of thing in the client side language?

Many thanks.

EDIT: Have also tried with no luck:

       CASE WHEN SUBSTRING(cc.contype, 1, 1) = 'C'
        THEN REPLACE(cc.contype, 'C', 'Signed')
       CASE WHEN SUBSTRING(cc.contype, 1, 1) = 'E'
        THEN REPLACE(cc.contype, 'E', 'Estimate') as ContractType,

Answer 1

Try doing it the other way round if you don’t want the new “y”‘s to become “z”‘s:

REPLACE(REPLACE(cc.contype,'y','z'),'x','y') as ContractType
