Re: External Re: Stored Procedure with large result set -- RPG400-L

Hi Jerry, could you be running into this restriction?

Using the multiple-row FETCH statement
The multiple-row FETCH statement can be used to retrieve multiple rows from
a table or view with a single FETCH statement. The program controls the
blocking of rows by the number of rows requested on the FETCH statement
(The Override Database File (OVRDBF) command has no effect.). The maximum
number of rows that can be requested on a single fetch call is 32 767.
After the data is retrieved, the cursor is positioned on the last row
retrieved.

Extracted from the IBM i Database SQL programming manual.

Sounds like you may be extending past the limit when you increase to 50,000.

Here is some of the code.

When I change the elements to 30000 it compiles. At 50000 it does not.

I have also tried it a Mult occurrence DS

// Result Set
Dcl-DS Results Dim(50000) Qualified Inz;
RCustNo Char(8);
RAttr Char(20);
RAttrDesc Char(100);

Jon,

Never said he was...given that he didn't mention the error, just that it
was a compiler error, I said it was an RPG limit..

Which one, I don't have enough info to know.

I assume this is an RPG program/prodedure being used as a SQL
externally defined stored procedure?

How is the RPG generating the results set?

Sounds like you're trying to build an array(?) in RPG and return
that as

a

result set?
And running into RPG limits, in that case nope.

You'd need to switch to using an SQL cursor to return a bigger
result

set.

Hi All,

I have a request for a Stored Procedure that will return a result
set

with

around 50,000 rows.
It seems the limit is set at around 32,000 rows, otherwise the pgm
will not compile.

There are over 3 million records in the file that I want to return
a subset.
This is called from the network side of the world.

Is there any way around this limit?
