My question is this: Given that I can't tell ADO.NET that what I'm telling it to call is a user-defined table-valued function rather than a stored procedure, am I at risk of it treating my call to a user-defined table-valued function as a parametrised query and therefore facing performance issues? Or is ADO. Stored procedure recompilation is one explanation for compile locks on a stored procedure or trigger. with every EXECute, if CREATE PROCEDURE included WITH RECOMPILE 3. However, I also know that ADO.NET only has a special ComamndType for stored procedures, so I don't know how it knows that it's talking to a user-defined table-valued function rather than passing around raw SQL. with the first EXECute, when the parse tree is read into cache 2. As far as I know, user-defined table-valued function are just as strongly typed as stored procedures, so the server shouldn't have to guess when using them. Option (recompile) requested Parameterized plan flushed Test plan linearization Plan affecting database version changed Query Store plan forcing policy changed Query Store plan forcing failed Query Store missing the plan You can get the same list for any other versions that support Extended Event tracing. My confusion comes from the article only mentioning stored procedures as a solution. The estimated recompile threshold starts an automatic recompile for the query when the estimated number of indexed column changes have been made to a table by running one of the following statements: UPDATE DELETE MERGE INSERT Specifying KEEP PLAN makes sure a query won't be recompiled as frequently when there are multiple updates to a table. The basic idea is that the server has to guess the data type of your parameters and its guesses pollute the cache. 3 In my databases I have some Stored procedure with recompile 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. This article warns of the performance pitfalls of using parametrised queries rather than stored procedures. While your stored procedure is running, you can simply recompile it.
