Re: Mapping SQL Result Sets to Browsers

Buck,

Thanks for your reply.  Especially your understanding of "consuming" the results of stored procedures in RPG.  It seems to validate my impression that stored procedures are more applicable to ODBC and JDBC clients.

Nathan.

Writing a stored procedure in RPG is very simple.  iSeries DB2 support 
lets one turn just about any program into a stored procedure with the 
addition of 'set result sets' and a 'create procedure.'  Very Cool.

Consuming a stored procedure in RPG is not nearly as nice.  The only way 
I know how to do it directly is via SQL CLI.  There's an old project on 
Sourceforge - iseriestoolkit - that was a great start to wrappering up 
the CLI for RPG programmers.

An indirect way is to have your RPG code call some Java code.  Java can 
consume the stored procedure, convert the result set into an array and 
pass the array back to RPG.

You can guess how much fun either of these are by the number of times 
we've seen solutions like these posted.
