Re: [U2] Trigger questions
Come on, Doug, you know documentation is usually treated as an
afterthought - way behind the software and usually incomplete. I'm glad
you got your trigger working.
Now, since I have no interest in learning Java, am I 1 or 10 of those
people? ;^)

The SQL syntax works fine once you get used to it

Subject: [U2] Trigger questions
I am sure I can do this but I am trying to figure out the best way
I need to write a WRITE trigger that does the following
Call a java web service to update an SQL table (no problem)
But if the update fails do NOT update the pick record and if possible notify
the user
My question is what would be the best method/way to do this?
Do triggers use transaction logging that I could roll back the record or should
I do something more manual? Copy the record (for example)
Any thoughts/suggestions/ideas welcomed and appreciated

Re: [U2] Trigger questions
While it's working I am getting back:
[error] SQL update failed
good
But I am also seeing
Error performing trigger for customer
but It works the record is not updated
Write failure
good
Any idea on why I am getting the error performing trigger when it's obvious
it's working?
Thanks

Re: [U2] Trigger questions
When/if you upgrade to UV 11.1 - perhaps you should use Index-based triggers - now supported by Rocket. Simpler than SQL-style triggers... see the new features.pdf in UV 11.1. Excerpt: In some circumstances, an application may not require all of the capabilities available to conventional triggers. In these cases, index-based subroutines may serve the purpose better because they have reduced overhead, which may translate to better performance. -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Doug Chanco Sent: Friday, 1 April 2011 3:19 AM To: U2 Users List Subject: Re: [U2] Trigger questions While it's working I am getting back: [error] SQL update failed good But I am also seeing Error performing trigger for customer but It works the record is not updated Write failure good Any idea on why I am getting the error performing trigger when it's obvious it's working?

Re: [U2] Trigger questions
By definition - if you're creating a write trigger the first parameter is the status. From Developing UniBasic Applications SUBROUTINE trigname(execstat, dictflag, filename, record.ID.expr, recordval) execstat The execution status returned by the trigger subroutine: 0 - No updates are allowed. 1 - Updates are allowed. 2 - Updates are allowed, using the return recordval. So if your before update trigger passes back a 0 as the execstat the write won't be performed. You'll just need to make sure the process calling the write can then deal with it.

Doug, In UniData you can test for STATUS() after the ON ERROR of a WRITE command. If the STATUS() is 2 then the WRITE failed in the Trigger. You can also set @USER.RETURN.CODE or use a COMMON variable to pass the error code/message. David A.

Re: [U2] Trigger questions
If you want to force the trigger to issue a rollback I think you need to
execute the SetDiagnostics function.
Something like...
subroutine TRIGGER.HANDLER(triggerName,schema,tableName,
event,eventTime,
newRecordID,newRecord,oldRecordID,oldRecord,
association,associationEvent,
triggerCount,chainCascade,cascade)
if someCheckCondition then
call updateThirdPartyApp(xxx, returnStatus)
if returnStatus 0 then
*// rollback and gracefully end processing.
z = setDiagnostics('[999] Third Party App update failed with: ': returnStatus)
end
end
