Hi !
I'm using WMQI 2.1 + CSD4
My question :
I want to code a java-like try-catch without using the trycatch block provided by WMQI.
I want to specify directly in my ESQL code the error code returned.
For example, I'd like to have something like that :
DECLARE that, this CHAR;
SET that = '12B4';
TRY
this = CAST(that AS DECIMAL)
CATCH
THROW USER exception catalog 'MyCatalog' message 1234 values ('not a numeric value');
Does it exist ? Is it possible to de someting approaching but without the trycatch node ?
Thanks in advance ! |

| Exception handling in MQSI is very primitive. There is no ESQL try/catch construct and you cannot nest Try/Catch nodes. The only good thing is the failure terminal on compute nodes that allows you to catch errors on just that node. |

Please don't re-open three year old threads!
No, v6.0 does not have a Try/Catch statement in ESQL.
You can declare an error handler, though, which acts the same way. It's just not try/catch.
