RE: Error Handling in SQLRPGLE Programs

["Andrew Lutz" <andrew.lutz@xxxxxxxxxxxx>]

I started using SQLCOD because it was more comfortable (i.e. MSGF
etc...)

But I soon discovered that there are errors that are not covered by
SQLCOD that are covered by SQLSTT (can't remember which ones at this
moment).

So here is my advice always, ALWAYS test SQLSTT.  But, utilize the
SQLCOD to build those unexpected or expected messages.

Another plug for SQLSTT, which is ANSI compliant, let's say your client
(receiver of error message) isn't on the AS/400, SQLCOD is very foreign.

Hi Bob,

SQLCOD 1-99 are warnings
SQLCOD < 0   are SQL-Errors.

If I want to display a SQL-Error-Message, I use the following trick:
All SQL-Messages are in the QSQLMSG Message-File
The Message-Id of an SQL-Error is SQL + absolute value of SQLCOD.
(SQLCOD -302 --> 'SQL0302')

On the other hand I wouldn't use WHENEVER, i prefere a simple IF in my
RPG-Program:

C                   Do       *HiVal

C/EXEC SQL
C+ Fetch SqlSKR into :DS_SQLSK
c/END-EXEC

C                   if        SQLCOD      = 100
C                   leave
C                   endif

C                   if        SQLCOD      < 0
C                   eval      MsgId      = 'CPF9898'
C                   eval      MsgTxt    = RtvSqlMsg(SQLCOD)
C                   exsr     SndPgmMsg
C                   leave
C                   endif

I hope that helps
