Why? Are you restricted by some administrator? All AS/400s (and iSeries and System i)…

It sounds like some sort of homework assignment for a query class.

I can only use SELECT RECORDS in AS/400.

Why? Are you restricted by some administrator? All AS/400s (and iSeries and System i) have had SQL available for the past 20 years or so. The major obstacle is that many sites haven’t installed some of the nicer interfaces for SQL. But it’s still in the system and can be accessed and used in a variety of ways.

I can write it in SQL but how can I write this nested query in Select records of AS/400?

That doesn’t make much sense. I assume that you must be seeing “Select records” on some screen from something like Query/400. (Why would you use Query/400? It’s been practically obsolete for well over a decade.)

Why not just use SQL?

Are you saying that you want to use AS400 query and not SQL?
Craig’s example will run on the AS400.
You can either do a STRSQL and run the statement or put that code in a source member and use the RUNSQLSTM c ommand.

Thanks Craig, I can only use SELECT RECORDS in AS/400. Is there any way to write that nested query using SELECT RECORDS?

Example of the table
Student No. Name Grade
1001 Michelle Fail
1001 Michelle Fail
1025 Peter Fail
1025 Peter Pass
1025 Peter Pass
