Is there any way to capture db2 return codes in mqsi? I know that if a 'not found' occurs, your xml will be null but what about other return codes? Some appear in the event log but not all. I would like to capture them in the flow so that I can report the appropriate information to the support staff.
Thanks in advance for any help! |

Hi,
as always life before 2.1 is hard, very hard.
In 2.0.x the only way to find out about SQL return codes is by analysing the exception list when a SQL exception is thrown. The codes
can be found usually at the second ot third nesting level in the the inserts section of the exception list tree, depending on where you
capture the exception. You can catch it in a localized fashion in the failure exit of a node or in a centralized way in try/catch node (or the input node for that respect) in the catch tree. You must evaluate it in a copmute node and based on what you get add your own error handler.
The typical strategy with fine grained database error handling usually works like this:
Do only a single database action per node
so you can be sure about the cause of an exception (you can find out the SQL statement from the exception list, too, if you want to).

| Don't forget there is also a support pac IA0J which will allow you to easily interrogate the returned SQL code without manually parsing the exception list. |

True, but it's support pack categrory 2,
so: use at your own risk ! And since
MQSI 2.1 has a more elegant way of doing
this you will probably never get support
for this. None of my customers ever
accepted usage of category 2 in critical
parts of my flows. Mike Brady's IA0J comes
with source code though, which in turn
makes it acceptable for me.
Parsing the exception list manually
is fully support though.
