The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
What is it you are trying to accomplish? Which one of many are you
trying to pick out? Why make the distinction anyway, as it appears that
you are simulating an EXISTS clause with your subselect? I suspect you
need more selection terms in your where clause on the subselect
statement.

Subject: How to limit rows read to 1 rows
I have a SELECT statement that returns more than 1 record for a invoice.
The
file can have 1 to many invoice records with the same invoice number.
I need a way to limit the select, to read only one of those invoice
records.
There is a solution using LIMIT, but I cannot get that to work.
Example:
Select * from table1 T1 where T1.INVOICE in
(Select T2.Invoice from table2 T2 where T1.Invoice = T2.invoice LIMIT 1)
TIA
