Talend MDM Views (Filter records using WHERE conditions)

Scenario: I have a customer record with fields Effective_From, Effective_To and Current Dates.

I will have to create a new View in Talend MDM so that only the records having the Current between the Effective_From, Effective_To dates are displayed.

 

Trail 1

I tried adding in the where condition, but it doesn’t let me compare the date values as the comparison is limited to String and Int.

So we have added new fields called FromDate, ToDate and CurrentDate which are Long values storing the milliseconds data. And even after doing this, it doesn’t allow me to do a field to field comparison.

 

WHERE CONDITIONS in View

Customer/From_Date <= Customer/Current_Date And

Customer/To_Date >= Customer/Current_Date

 

Caused by: com.amalto.core.util.CoreException: org.apache.commons.lang.NotImplementedException: '>=' support not implemented for field to field comparison.

               ... 77 more

Trial 2

I tried converting into number and implementing but still no luck.

WHERE CONDITIONS in View

Customer/From_Date <= number(translate(Customer/Current_Date)) And

Customer/To_Date >= number(translate(Customer/Current_Date))

What could be the possible scenario here ?

Any help will be appreciated. Thank you

It is Talend 6.1

 

I have checked with the Talend guys, and looks like this functionality can't be done.
