Re: Can I QMHRCVPM messages generated by embedded SQL

Rather than retrieve the message sent to QSQROUTE (not possible unless you
know the message key of the message) you can use SQLCODE and message data
supplied to send your own copy of the message. I've posted some sample
code:

All,

I am trying to generate a meaningful error message in case of errors
thrown
by embedded SQL. To that end, I wanted to create a proc like this:

p GetSQLErrMsg b
d GetSQLErrMsg pi 10i 0
d SqlState 5a Const
d SqlCode 10i 0 Const
d ErrorMsg 60a

d ReturnCd s 10i 0

d RCVM0100 DS qualified
d BytesRtn 10I 0
d BytesAvail 10I 0
d MsgSev 10I 0
d MsgID 7A
d MsgType 2A
d MsgKey 4A
d 7A
d CCSID_status 10I 0
d CCSID 10I 0
d MsgDtaLen 10I 0
d MsgDtaAvail 10I 0
d MsgDta 8000A

d MsgKey s 4A Inz(*ALLx'00')
d I s Like(tInteger) Inz(5)
d J s Like(tInteger)
Inz(%size(ErrorMsg))
d wwMsg s Like(ErrorMsg)

d ds
d InMsgID 7a
d SQLText 3a Overlay(InMsgID) Inz('SQL')
d MsgNbr 4 0 Overlay(InMsgID:4)

/free

ReturnCd = OK;
MsgNbr = %abs(SqlCode);
wwMsg = 'SQL Failed. SQLSTATE = ' + SQLSTT + ' SQLCOD = '
+%char(SQLCOD);
if (SqlCode < 0);
monitor;
// check the last 5 messages
dou ((RCVM0100.MsgID = InMsgID) or (I = 0));
QMHRCVPM( RCVM0100: %size(RCVM0100): 'RCVM0100': '*': 2:
'*PRV':
MsgKey: 0: '*SAME': ApiError);
I -= 1;
MsgKey = RCVM0100.MsgKey;
enddo;
//* retrieve message data so that it can be printed on the
screen
if (I > 0);
if (RCVM0100.MsgDtaLen < J);
J = RCVM0100.MsgDtaLen;
endif;
wwMsg = %subst(RCVM0100.MsgDta: 1: J);
else;
wwMsg = 'SQL Failed. SQLSTATE = ' + SQLSTT + ' SQLCOD = ' +
%char(SQLCOD);
endif;
on-error;
Returncd = GeneralError;
endmon;
endif;

ErrorMsg = wwMsg;
return ReturnCd;

/end-free
p GetSQLErrMsg e

But the message that I want to capture, SQL0805 (SQL package TN050P in
TTN001N not found at DRDA Server), seems elusive. This message, and some
others, are sent by QSQROUTE as follows:

Press Enter to continue.

This is my call stack at the time I try to capture this message:

Can someone tell me what I am missing or doing wrong.
