Though t2 has no alter table against it, the insert. The stored procedure below (proctest) has two temp tables (t1 and t2). In the case of temp table, if you have one alter statement on any of the temp tables, statements involving all tables will recompile. Explicit recompilation eliminates the need for implicit run-time. Recompiling a stored procedure with every execution is one of the less efficient ways to combat query plan issues caused by parameterization. Now again creating that stored procedure with RECOMPILE option. It turned out that this customer had some alter table statement on the temp table. If there is already a plan in cache for this specific stored procedure, it’s intact. With Recompile will recompile a new plan for the entire stored proc ,everytime its run. Use the ALTER PROCEDURE statement to explicitly recompile a standalone stored procedure. When executing a stored procedure with a WITH RECOMPILE option in the EXECUTE statement, a new query execution plan is created and used for this specific execution, but it’s not stored in cache. When you restart Sql Server, that will have the same effect. Changing the table structure forces a new execution plan, but just adding an index does not. How can I do this without repeating OPTION (RECOMPILE) after each query? create proc usp_test Yes, you should recompile the stored procedures (you can use sprecompile ). Therefore a subsequent execution of that object finds no plan in cache which triggers a. When you execute sprecompile on a stored procedure/trigger/UDF, that object is immediately removed from plan cache (Cache Remove).
Inner queries or just execution plan,i am not sure what does this mean ? With Recompile at Stored proc level,will cause recompilation every time the proc is executed and query is not saved to Cache Running sprecompile on a stored procedure, function or a trigger causes it to be recompiled the next time they are executed.
Does the WITH RECOMPILE on stored procedure recompiles inner queries or just the execution plan for an entire SP?
