What I don’t see is how to construct nested data that would be suitable for use with a child table in a table group. I have a parent dataset that I’m constructing via script due to annoying limitations of an ancient SQL Server 2000 instance. I need a subquery for each row that could be done with a normal query, but there’s no way to add a regular subquery to a s… et un `itertools.groupby`. Mais te lances pas là dedans tout de suite, attends un peu d'avoir d'autres avis. --- _[View the full topic](https://forum.inductiveautomation.com/t/error-report-viewer-using-nested-query/83090)._
