Comparing with TQL

Hello,

 

We are trying to update a field with the Enrichment process in UCMDB. We need to compare values of two fields in the TQL if that gets passed then it should update a value on another field with Enrichment.. But I'm not able to compare the two fileds with TQL.I think I might be missing something. Can it be done with TQL itself or do we have any other way to achive this in UCMDB.

 

Example:

 

Field 1: abcd

Field 2: abcd

 

Then the required result should be as follows.

 

Field 3: Final value

 

Thanks in advance..
