Using context Variables in DQ

Daemon_demon — Fri, 15 Nov 2024 22:49:46 GMT

Hi,

I am using talend Data Fabric in which i am creating a Job in DI to run my DQ analysis using tDqreportrun component.

I am using context variables in DQ as data filter.

Is it possible to change the value of that context variable at run time using DI and use it in DQ.

Thanks!!

Please note :

I do have the same variable which i am using in DQ, i am updating it's value in runtime , but the DQ is not taking the updated value , but only taking the value of the variable which was defined statically {If the original value is blank, it is taking blank}

I found the answer !

Turns out , we can access the context variables across DI and DQ.

I was setting the context variables as context.Var = "New Value", as this(context-var) is stored in a temporary storage , the DQ rules were not taking the updated values but were taking the values which were defined at the start of the Job.

Instead of context.value = "Value", You can use context.setProperty(<context-var-name>,<updated value>).

That should do the trick !
