Dear All,

Do we have any common programming logic in COBOL for the following scenarios.


1. One to One match
2. Left Outer Join (Similar to SQL join logic)
3. Right Outer Join (Similar to SQL join logic)
4. Full Outer Join (Similar to SQL join logic)


Note:-
Both the files are not of same layout.
But they do have common key variable like Account Number
Both the files are sorted based upon key variable

Please help or Guide me to overcome the above scenarios.

There is a 'button' at the top of the page - PROGRAMS.

there is a lot of logic there.

Also, if you google, you will find thousands of sites with examples of programs.

Ibm's developer works technical manuals provides many examples.

ibm redbooks' site provides examples.

you are obviously just learning,
so you will need to do a lot of research and wade thru the 'advanced stuff'
to find answers to such basic questions as you have posed.

Hello,

Near the top of the COBOL part of the forum is a "sticky" with working 2-file match/merge code. This will do most of what you want. Many-to-many will depend on the rules of the requirement.

That code works as so all you need to do is modify the record layouts and key location.

To download, use right-click and "save as".

With qsam files this is not a "join" - possibly i misunderstand something.
