Question

I need to us a sql query in java that has an IN clause in it. I have seen suggestions for doing this when the IN clause is a predetermined set, such as numbers which won’t work in this case because the set will be dynamic. Here is what I am trying to do:

select c.cust_name 
from cust_acct c, has h 
where c.cust_id=h.cust_id 
    and h.sh_add in (select a.sh_add from address a where sh_st='VA')

I do not get any faults. That is, the code runs I just get no results for this particular query

Answer 1

Have you checked that you are getting the right intermediate results from select a.sh_add from address a where sh_st='VA'?

You could just rewrite the query as:

select c.cust_name 
from cust_acct c
inner join has h 
on c.cust_id=h.cust_id 
inner join address a
on h.sh_add = a.sh_add
where a.sh_st = 'VA'
