Hello: When I create a query rule of all rows of a CDT that contains

The comment left by Eduardo certainly works. The solution uses apply to loop through every element in the one-to-many nested CDT and build the array of elements. I agree that it works, but the performance is dreadfully slow for large data sets, which is a definite possibility for our data requirements. The point of this topic on the Appian forum to point out something that logically should be possible, but results in an error. Using a looping function would be much slower in almost all cases than having Appian moving the entire dataset through memory. Thank you.
