RE: Converting an RPG I/O to SQL

Brian,

This is where you need to use a cursor and the FETCH statement.

After doing the fetch, you can check SQLSTATE ( RPG name SQLSTT ).

An SQLSTATE of '02000' means after a fetch means no-data returned.

If you use a Multi-Row fetch, you can find out how many records were returned 
by looking at SQLER3.


HTH,
