SQL taking too much time for executing a query

Question

i am using below query to generate some information of around 7k lines. but the issue is that the query is taking too much time to complete just 7k line. i need to fine tune it.

Answer 1

I use the SQL Profiler to auto create the indexes needed for a fine tune query.

• Enter in SSMS (SQL Server Management Studio) -> Tools -> SQL Server Profiler.

• Click Connect, and then click Run, to start a new trace.

• Execute your slow query now, so the profiler can capture and record it.

• Stop the query and File -> Save it.

• In the menu, click Tools -> Database Engine Tuning advisor.

• Click Connect when it opens, and in Workload, select file, and click the first button on the right (binoculars one). Then select the file you have just saved.

• Select now the checkbox of your database, and click the "Start Analysis" button (below the "View" and "Action" menu).

• Once it finish, open "Action" menu, and click in "Apply Recommendations".

Now you should have a fast and fine tuned query.
