The SQL query provided is a solution for the given problem. Here’s an explanation of how it works: CTEs (Common Table Expressions) The query uses two CTEs: BusinessViews and BusinessClients. BusinessViews: This CTE selects all BusinessViews records with their respective id, createdAt, businessId, and userId. It includes multiple rows to simulate the scenario where there are many BusinessView records. BusinessClients: This CTE selects all BusinessClients records with their respective id, status, createdAt, userId, createdBy, and businessId.
