Question

Can I have an IF statement in my select query or in an update query?

I want to set different values based on some substring values in my DB.

Answer 1

you would use a CASE statement

select case Column when 'a' then 'bla' else 'not bla' end as SomeColumn
from SomeTable

Runnable example

select case xtype 
when 'p' then 'stored procedure' 
when 'd' then 'default'
when 'u' then 'table'
else 'something else' end as SomeType
 from sysobjects
