Hi, I want to write a select subquery.

Basically if I have a list of fields I am calling, i.e.

select
u.user, ua.ip,u.log... etc
from user u join useraccess ua etc.

I want to write an subquery that will return nothing, i.e. ‘’, or if the u.loginname value is like ‘ut%’ then what is in the field u.loginname

I’ve tried writing if/else statements, case statements and creating a variable but I can’t get it to work?

Any help would be appreciated??

If anyone needs more info to help me out Let me know and I'll gladly provide.

Thanks
Steve
