Question

I have two tables I’d like to compare. They are in separate databases and servers as well. I’ve added a linked server and can query this from within Server 1.

Table1 on Server1 provides breakdowns of submitted data. For example ref#123 may appear 3 times with values of 100, 150, and 200 (total 450). I want to compare Table2 on Server2 that also has ref#123 and the totals, and return the correct record if the total is different to 450.

Hope this makes sense! Thanks

Answer 1

select *
from
(select col1, SUM(col2)
from table1
group by col1) t1 INNER JOIN
(select col1, col2
from table2) t2 ON t1.col1 = t2.col1 where t1.col2 <> t2.col2

table 1 is table where ref#123 can appear multiple times.
col2 contains values 100,150,200 e.t.c
