Enhancement: HAVING clause for declarative grouping and aggregation

[Isomorphic]

A feature similar to this is already being tracked as a possible enhancement.

Thanks for sharing the code to do it via customSQL.

For anyone with a similar problem, my current solution looks like this:

<operationBinding operationType="fetch" operationId="fetchDuplicates" requiresRole="serverOnly" outputs="CSVFIELDNAME">
    <customSQL>
        SELECT $defaultSelectClause FROM $defaultTableClause
        WHERE $defaultWhereClause
        GROUP BY csvfieldname
        HAVING COUNT(*) > 1
    </customSQL>
</operationBinding>

Hi Isomorphic,

I just came across a use case, where I could use a <having>-clause in my operationBinding.
I think I can solve it with customSQL as well, but of course it would be nicer in .ds.xml.
Could you note this as enhancement to the declarative grouping and aggregation features from 4.1?

Thank you & Best regards
