Hi there,

I need to grab some items into a where clause, see below:
table1
ID | Location
10| New York
11| Dallas
...

select * from table2 where Location = 'New York' or Location = 'Dallas' ...

How can I select Location from table1 to where clause in table2?
Thanks in advance.

select * from table2 where location in (select distinct location from table1)

select * from table2 where Location in (select location frrom table)

or
select t2.*
from table2 t2
join table1 t1
on t1.location = t2.location

==========================================
Cursors are useful if you don't know sql.
SSIS can be used in a similar way.
