Unfortunately you cannot handle SQL Cursors/SELECT Statements
What you can do:
1. Write a RPG Function that will execute the SQL command and return the
Result
2. If you want to do it only with SQL:
The easisest way is to create a View in the QTEMP, Declare the view as file
and read the file with RCVF
Something linke this:
DCLF FILE(YourView)
RUNSQL SQL('Drop View QTEMP/YourView') COMMIT(*NONE)
MONMSG MSGID(SQL0000)
RUNSQL SQL('Create View QTEMP/YourView +
as (Select . . . +
FROM . . . +
. . .) +
RcdFmt YourViewF') +
COMMIT(*NONE)
RCVF RCDFMT(YourViewF)
MONMSG MSGID(CPF0864) EXEC(DO)
/* Whatever you want */
ENDDO

Subject: How to retrieve SQL results into CL pgm
How can I run an SQL statement and retrieve the results into a CL pgm?
For example, I want to SELECT COUNT(*) FROM QSYS2.ASP_INFO: but I want to
run it using RUNSQL in a CL program and get the COUNT into a variable in the
CL program.
Something like this:
DCL &COUNT *DEC LEN(1)
RUNSQL SQL( SELECT COUNT(*) FROM QSYS2.ASP_INFO) and get the SQL statement
result in the CL &COUNT field.
Ultimately, I want to do different things depending on whether there is 1
ASP or more than 1 ASP so I'm really after the count of ASPs on the system.
If there is a better way to do this within CL, I'm open to suggestions.
Thanks,
Steve McKay
