how to terminate tFlowToIterate

Anonymous — Tue, 02 Aug 2016 04:22:25 GMT

Hi,
I am new to Talend and I need help with tFlowToIterate...
I have a talend job with the following components:

MySQLInput(extract records) -> tFlowtoITerate(column id) ->tJavaRow(To check if records from MySQLInput are valid)->RunIF (run if valid) -> mySQLOutput (insert recrods) - > send mail (email alert that new rows were inserted)

When I run this, if for example I have a total of 20 records extracted and 10 records a valid, everything from tJavarow including the send mail component will execute ten times. With this, I will receive ten email alerts. I only want the send email component to run/execute after tFlowtoIterate has completed with its iteration/loop so I only get to receive one email notification.

The problem is I don't know how to this in Talend. Please help.

Thank you!

Hi,
Are you using OnsubjobOk connector between your tmySQLOutput and tsendmail component? Could you please post your current job design screenshot into forum?
Best regards

hi!

Thanks for the reply. Nope, I am not using OnsubjobOk , I am using OnComponentOk. Please see below. The SendMail component should run only once, i.e., after the process has completed the iteration. Btw, I am using Open Studio.

Hi,
Have you tried to use onsubjobok instead to see if [font=Verdana, Helvetica, Arial, sans-serif]you[/font] will receive only one email alert till the whole subjob (tMysqlinput-->tflowtoiterate-->tjavarow...) finish?

hi, sorry for the late reply.

yes, that solved the problem. I used onsubjobok from tflowtoiterate component to sendmail component.

Thank you so much!
