SeRQL Extensions "Finished extensions:
- column alias (AS)
- set operators (UNION/MINUS/INTERSECT)
- query nesting (IN)
- quantification (ANY/ALL)
- grouping (GROUP BY/HAVING)"
Based on the attached PDF the only things extra to iTQL is column alias and the aggregate function SUM (we have COUNT). The syntax is different and perhaps SeRQL is better although the use of IN in iTQL leads to less verbosity. They've also got slated recursion which is similar to trans and walk. It's good to see all stores reaching a common level of functionality. We have to get OPTIONAL and some other things to catch-up too.
