First, thanks to the help from "Grand Poobah", I setup my catalog and odbc.
I tested my remote SP from DB2 CLI, successfully by
db2=> call DB2SP_GETCUSTNAME (10030-134, ?, ?)
A_RETURNCODE: 0
A_RETURNMESSAGE: Brian C Clipper
"DB2SP_GETCUSTNAME" RETURN_STATUS: 0
In my compute node ESQL, I define the procedure:
create procedure CallMySP
(in ID char,
out returnCode integer,
out ResultMsg char) language DATABASE
external name "DB2SP_GETCUSTNAME";
here's the code I use to call the procedure:
...
declare ret_code integer;
declare msg char;
call CallMySP(InputBody.ID, ret_code, OutputRoot.MRM.CustName);
Although the out parameter ret_code is assigned to 0, the OutputRoot.MRM.CustName didn't get populated.
It seems to me only character field has such problem. Can anyone shed some light on this? It must be sth trivial I'm missing.
many thanks,

that's what I did. it got assigned only an empty string, of length 1, just as the current output msg. No exception though.
thank you.
