Re: Weird Error - CPF3E01 - DDM parameter value not supported. (using Db2 Connect driver for .NET Core)

DS is 53 bytes...

DIM(9999)--> 529,947 bytes total

1192 records --> 63,176 bytes
1193 records --> 63,229 bytes

Doesn't seem to hit any limits I'm aware of...
Unless DDM is more limited than JDBC...

What's the total size of the data structure for 1192 elements?

Calling an external stored procedure written in RPG.

As long as the results set is 1192 records or less, it works fine, but

any

bigger and we get the following exception on record 1193.

Doesn't matter what's in the results set, only if it bigger than 1192.

Calling the same store proc via JBDC using ACS Run SQL Scripts works

fine.

One thing that's a little different, the results set is built as an RPG
Array...

dcl-ds my_data qualified dim(9999);
ENTERPRISE char(4);
COMPANY char(3);
EMPLOYEE_ID char(9);
TECH_ID char(3);
//other fields snipped
end-ds;
dcl-s OutputRows int(10);

Exec SQL Set Result Sets
WITH RETURN TO CLIENT
ARRAY :my_data
FOR :outputrows ROWS;

Thoughts?
