I would like to populate a table on a record view that reads its data from an Oracle VIEW. I use the a!queryEntity to query the data. The query works fine when reading from existing tables in DB; but gives the attached error when I apply it on the view.

When I try to query the Oracle View from Oracle developer, I realize it really takes a long time to obtain the results. So, most likely it is a time out issue.

Do you recommend any optimizations to Oracle View to better integrate with Appian?

@mohamedb - we faced similar issue where query optimization was required. We added index on tables which were joined in the query. Also we divided the queries into multiple small queries and checked which part of view is slow. Another option we tried was to use stored proc as it limits the data to minimum extent as compared to views.
