I would be more keen on the option(recompile) if that is possible. There is a stored proc in the Master called SP (system stored proc) Procoption you can use it to auto start all your stored procs. The better solution is to force SQL Server to put all your stored procs in the procedure cache on start up. If a query is poorly written then the execution. This command first recompiles all objects upon which this procedure depends if any of those objects are invalid, the procedure being recompiled will also be. In many cases, a poorly written query will cause significant performance hits.
However, if you are still seeing performance concerns, continue to review the execution plan and step through the stored procedure. Now, the CPU usage stayed beyond 90 constant. WITH RECOMPILE can kill an Asp.net application because HTTP is stateless. With a little luck a quick recompile of the stored procedure will resolve the issue. The way I find them is: SELECT OBJECTNAME(ID)AS SPNAME, FROM SYSCOMMENTS WHERE TEXT LIKE 'WITH RECOMPILE' when I look at: select from sys.procedures I find no indication of recompiles. In order to mitigate this, we have changed the procedure to do a recompile every time it executes. In my databases I have some Stored procedure with recompile. As the number of execution grows, one of the bad plans causes a 100 CPU spike. ALTER Procedure spGetEmployeeDetailsById ( ID INT ) WITH RECOMPILE AS BEGIN SELECT Name, Gender, CAST(DOB AS DATE) AS DOB FROM Employee WHERE ID ID END In the next article, I am going to discuss the User-Defined Functions in SQL Server with examples. There is a heavily queried stored procedure that uses a bad plan once in few days. If you are writing a SQL queries or stored procedures, probably sometimes you noticed that stored procedure execution sometimes is quick and sometimes is. Stored procedures will recompile is that the developer has place interleaving Data Definition Language operations with Data. With Recompiled Attribute in SQL Server Stored Procedure: Whenever a procedure is compiled for the first time it prepares the best execution plan according to the current state of the database.
#STORED PROCEDURE RECOMPILE CODE#
There are differences between adding option(recompile) within the code and creating a stored procedure with recompile. Alter the stored procedure to use the Recompile option. I have a couple of questions regarding the procedure below:ġ) is it a good candidate for parameter sniffing?Ģ) how could I add option(recompile) within the code? In my current environment, I have many instances of stored procedures, just like the one shown below, where a bunch of parameters are passed to the procedure, and then within the procedure a select exists is run and based on the result, different logic paths are run within the stored procedure.
