Sengott,

I'll give the same advice as a recent posting to help you know where there is some excellent help for this type of question.

Click on the "Search the Technical Documentation Library" button at the top right of this page. Now choose "WebFOCUS Reporting" in the top left hand select and type "Creating a Concatenated Join" in the text box below. Now click on the GO link and you will see a list of documents that will help you.

Tony,

I have gone thru the doc "Creating multifield join" from the Technical Document Library but they ve given the example for FOCUS data source, that method is not supporting SQL server database. We cannot select 2 Columns from one table at a time to join with single column in the other table.Please help.

Sengott,

If you are using MFDs then the process is the same. However, if you are accessing MS SQL sources then I would advocate you using SQL passthru and thereby achieving all your extract requirement within SQL and not FOCUS.

Rule number 1 - make the RDBMS do as much of the work for you as possible!
