Follow up concern.... Use of the cross-connection is untenable. After struggling with it all day, I can only conclude that, functionally, TDP seems to have a similar issue to early 3.x versions when using subqueries. I cannot confirm that this is sub-query related only, but each action I try to take on the query (using query builder), such as recoding the 'where' clause adding "group by" to a field, etc., results in delays as long as fifteen minutes before the program will allow further interaction.
Is this a known issue? Should I be avoiding the use of sub-querying when using cross-connection?
Thanks!
EDIT: Further struggling with this query into the evening confirms to me that delays are within the subqueries only (all data sources, though larger tables result in substantially longer delays, as if the system is flushing through the underlying data each and every time I modify the query). Within the main query, it functions just fine.
