RE: How to limit rows read to 1 rows

Darryl,



You can limit the number of returned records by adding fetch first row only
to the SQL statement.





Select * from table1 T1 where T1.INVOICE in

(Select T2.Invoice from table2 T2 where T1.Invoice = T2.invoice)

Fetch first row only



I hope this helps.

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
