How do I add a filter in OAC with a regexp_like condition?

Summary

I need to create a report in OAC by joining two tables based on regexp_like condition. How do I specify this in OAC?

Hello,

I've two separate datasets pointing to two different tables (Merged_DS_Table and Operation_List) in OAC.

I've created a report in OAC by including both the datasets and this has auto-created join between the two datasets based on the common columns between them (cs_method and cs_uri). Below is the query, it has internally used for the join condition

select * from Merged_DS_Table a, Operation_List b where a.cs_method=b.cs_method and a.cs_uri = b.cs_uri;
