I’m offering a 75% discount on to my blog readers if you click from here. If this is the kind of SQL Server stuff you love learning about, you’ll love my training. There are some other potential issues, like plan compilation overhead, and there have been bugs around it in the past. I don’t usually advocate for jumping right to recompile, mostly because it wipes the forensic trail from the plan cache. You can only do that by adding OPTION(RECOMPILE) to the query, like this: SET = + N'Ĭhalk this one up to “maybe it wasn’t parameter sniffing” in the first place. That doesn’t recompile the query that sp_executesql runs. WHERE v.CreationDate >= sys.sp_executesql = RECOMPILE
SQL SERVER RECOMPILE HOW TO
Recently, I saw someone use it like this: DECLARE DATETIME = '20101230' Applies to: SQL Server (all supported versions) Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW) This topic describes how to recompile a stored procedure in SQL Server by using Transact-SQL. If SQL Server has already spent time in finding the optimal plan for a given query. The queries used by stored procedures, or triggers, and user-defined functions are optimized only when they. The query plans are cached because compilation of a query is a time consuming task. The qualified or unqualified name of a stored procedure, trigger, table, view, or user-defined function in. The goal of compilation is to reuse the plan by caching it in memory. One common “solution” to parameter sniffing is to tack a recompile hint somewhere. Before trying to understand recompiling, though, it’s important to understand compilation in SQL Server. Like, if I passed in , we probably wouldn’t like a lookup too much. That’s an example of how parameters are sniffed. This method will recompile the stored procedure in the first run of the stored procedure. Here is a neat trick where you can make your stored procedure for recompilation but not actually execute it. Det är gratis att anmäla sig och lägga bud på jobb. Method 2: sprecompile for Recompile Stored Procedures. If I re-run the query and use the date, we’ll re-use the key lookup plan.

WHERE v.CreationDate >= sys.sp_executesql = give us the key lookup plan you see above. You can see the associated compiler error messages with the SQLPlus. Let’s paramaterize that! DECLARE DATETIME = '20101231' Use the ALTER PROCEDURE statement to explicitly recompile a standalone stored. What a difference a day makes to a query plan!
