Re: How to make correct join

As I recall the statement it's something like this

Select distinct dbo.Account.AccountNo as AccountNo
From dbo.Account inner join dbo.Groups
On dbo.Groups.AccountFrom <= dbo.Account.AccountNo AND
dbo.Groups.AccountTo >= dbo.Account.AccountNo

Hope you have a solution for me. I have tried different ways but don't
seme to get it right.

This is certainly better, since it relieves you from the DISTINCT:

SELECT a.AccountNp
FROM dbo.Account a
WHERE EXISTS (SELECT *
FROM dbo.Groups g
WHERE a.AccountNo BETWEEN g.AccountFrom AND g.AccountTo)

But whether that really addresses your issue, I cannot tell, because
your posting was very clear.

If this query does not work out, I suggest that you post the following:

o CREATE TABLE statements for your tables.
o INSERT statements with sample data.
o The desired result from the sample.

This permits anyone who wants to answer to copy and paste into
a query tool and develop a tested query.
