Question

is there anyway that i can basically do the following in a sql clause ,(i know syntax isn’t correct, but that’s not the point, it’s the idea)

set rs = select title, copy, masterID from table1

//if the masterID is not 0 then instead of using the copy from table1, use the copy from table2

if masterID<>0 then
set rs2 = "select copy from table2 where masterID =" & masterID
copy = rs(0)

I hope that makes sense. Look forward to hearing your responses. Thanks!

I think what you want is:

select title, 
       case when t1.masterID <> 0 then t2.case else t1.case end as copy, 
       masterID
from table1 as t1
left join table2 as t2
    on t1.masterID = t2.masterID
