Evolve reports work on predefined SQL Views. SQL Views are fixed; you cannot create or modify them.
When you create reports in Studio Manager, you can view the predefined SQL Views and their fields. And, you can write complex SQL queries to bring data into the reports.
Note:
When creating a SQL query, use only the view name in the from clause; do not include the database name or schema. For example: Valid query: Select Column from ViewInvalid query: Select Column from db.schema.View
