Hi,
Wanted to understand on how Appian parses an Expression Rule that uses a!queryAggregation and a!queryAggregationColumn against a Table/View? Does it convert and send a query as-is with GROUP By to the database SQL engine or does it get the data and then do the grouping on-fly in its memory?
Thank you in advance for your response.

Appian translates the expression into a corresponding SQL query and sends it to the database.
When these aggregation functions are used, Appian generates SQL queries that include GROUP BY clauses, and these queries are sent to the database engine for execution. Appian does not bring all the data into its memory and then perform grouping on it.
All,
Thank you for the quick responses. Very much helpful !!!
