RE: How to limit rows read to 1 rows

["Dean Olson" <dolson@xxxxxxxxxx>]

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.

 

Warm Regards,

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
