If we need each and every time then go for the first method. If next time we call the procedure without recompiling, the stored procedure will execute from the execution plan. This kind of execution is for one time only. We can execute the stored procedure with this recompiling option. The stored procedure which has parameter should be recompile for the parameter based results.Ĭreate Procedure Precuderenam e With RecompileĬreate Procedure MyProcedure WITH RECOMPILE The stored procedure result will vary based on the parameter passed. Use WITH RECOMPILE option if the stored procedure has parameters. Sql Server compile this each and every time of execution. Lets assume that I have two stored procedures, PROCA, PROCB. sprecompile looks for objname only in the current database. If we create stored procedure with recompiling option sql server doesn't get the execution plan for this stored procedure. The queries used by stored procedures and triggers are optimized only once, when they are compiled. Now, the CPU usage stayed beyond 90 constant. In order to mitigate this, we have changed the procedure to do a recompile every time it executes. 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. As the number of execution grows, one of the bad plans causes a 100 CPU spike. We can set the recompiling option while creating the stored procedure. There is a heavily queried stored procedure that uses a bad plan once in few days. Recompilation is the same process as a compilation, just executed again. This query execution plan is often stored in the cache to be quickly accessed. This is for set the recompiling option for the existing stored procedures.Ĭreating Stored Procedure with Recompiling option What is the RECOMPILE option The compilation is the process when a query execution plan of a stored procedure is optimized based on the current database objects state. The existing stored procedure can be set for the recompiling from the upcoming executions. EXEC StoredProcedureName parameters WITH RECOMPILE. Recompiling for an Existing Stored Procedure You can recompile your stored procedure while you execute it. If the programmer thinks to compile the store procedure each and every time then, can use this method to recompile the stored procedure. Normal execution doesn't tries to create a new data access plan from the database, It tries to get the information from the execution plan. By the normal way of stored procedure execution, the stored procedure will calls from the execution plan. Recompiling a stored procedure is necessary when the stored procedure changes every time of calling. I have this stored procedure.when i told the developers that it is not recommended to use with Recompile option they replied 'This was because this SP can be called with a number of different params and we wanted the optimizer to grab a new plan with each call (not ideal, but it was an attempt to get it to run more reliably faster each time vs.
