This means the records from the tables are displayed based on who the user is and to which records do the user has access to. This is usually done to allow specific users to have access to their data only without permission to view other users’ data.

The sp_executesql is a built-in stored procedure in SQL Server that enables to execute of the dynamically constructed SQL statements or batches. Executing the dynamically constructed SQL batches is a technique used to overcome different issues in SQL programming sometimes. For example, when we want to determine the displayed columns in our reports, this procedure might be a solution option for us. In the simplest sense, this procedure takes a dynamically constructed SQL batch and other parameters, then execute it in the runtime and, finally, it returns the result.
