Explanation:

Step 1: ALTER DATABASE CURRENT SET COMPATIBILITY_LEVEL Sets certain database behaviors to be compatible with the specified version of SQL Server. Syntax: ALTER DATABASE database_name SET COMPATIBILITY_LEVEL = { 150 | 140 | 130 | 120 | 110 | 100 | 90 }

Step 2: UPDATE STATISTICS Customers UPDATE STATISTICS updates query optimization statistics on a table or indexed view.

Step 3: EXEC sp_recompile N’ ‘Manage_customer’ sp_recompile causes stored procedures, triggers, and user-defined functions to be recompiled the next time that they are run. It does this by dropping the existing plan from the procedure cache forcing a new plan to be created the next time that the procedure or trigger is run
