Some Tips For optimization
Include the SET NOCOUNT ON statement into your stored procedures to stop the message indicating the number of rows affected by a Transact-SQL statement.
This can reduce network traffic, because your client will not receive the message indicating the number of rows affected by a Transact-SQL statement.
Call stored procedure using its fully qualified name.
The complete name of an object consists of four identifiers: the server name, database name, owner name, and object name. An object name that specifies all four parts is known as a fully qualified name. Using fully qualified names eliminates any confusion about which stored procedure you want to run and can boost performance because SQL Server has a better chance to reuse the stored procedures execution plans if they were executed using fully qualified names.
Consider returning the integer value as an RETURN statement instead of an integer value as part of a recordset.
The RETURN statement exits unconditionally from a stored procedure, so the statements following RETURN are not executed. Though the RETURN statement is generally used for error checking, you can use this statement to return an integer value for any other reason. Using RETURN statement can boost performance because SQL Server will not create a recordset.
Don’t use the prefix “sp_” in the stored procedure name if you need to create a stored procedure to run in a database other than the master database.
The prefix “sp_” is used in the system stored procedures names. Microsoft does not recommend to use the prefix “sp_” in the user-created stored procedure name, because SQL Server always looks for a stored procedure beginning with “sp_” in the following order: the master database, the stored procedure based on the fully qualified name provided, the stored procedure using dbo as the owner, if one is not specified. So, when you have the stored procedure with the prefix “sp_” in the database other than master, the master database is always checked first, and if the user-created stored procedure has the same name as a system stored procedure, the user-created stored procedure will never be executed.
Use the sp_executesql stored procedure instead of the EXECUTE statement.
The sp_executesql stored procedure supports parameters. So, using the sp_executesql stored procedure instead of the EXECUTE statement improve readability of your code when there are many parameters are used. When you use the sp_executesql stored procedure to executes a Transact-SQL statements that will be reused many times, the SQL Server query optimizer will reuse the execution plan it generates for the first execution when the change in parameter values to the statement is the only variation.
Use SQL Server Profiler to determine which stored procedures has been recompiled too often.
To check the stored procedure has been recompiled, run SQL Server Profiler and choose to trace the event in the “Stored Procedures” category called “SP:Recompile”. You can also trace the event “SP:StmtStarting” to see at what point in the procedure it is being recompiled. When you identify these stored procedures, you can take some correction actions to reduce or eliminate the excessive recompilations.
