I sample this using a really bad way by casting the XML to string and then doing a wildcard search however XML queries are not things most do every day and string wildcards are easy for everyone. SELECTĪnd cast(qp.query_plan as nvarchar(max)) like '%loop%' The XML query plan (the first column in both queries), contains the XML of the execution plan allowing you, in SSMS to click on it and view the actual plans but also allows you to scan for things you do not like to have like index scan or "god forbid" table scans. Join sys.objects as so on so.=QP.objectid There is a lot more data to look at, like how often is a procedure executed according to query cache SELECT Looking at the plans on a production server with the statistics of the data in the production server may show a different plan then of a dev box with a smaller dataset. WHERE objtype = 'Proc' and cp.cacheobjtype = 'Compiled Plan' SELECTĬROSS APPLY sys.dm_exec_sql_text( plan_handle)AS SQLTextĬROSS APPLY sys.dm_exec_query_plan( plan_handle)AS QP EXEC Purchasing.There are quite a few ways to get the actual execution plan of a stored procedure. To run the modified stored procedure, execute the following example. INNER JOIN Purchasing.ProductVendor AS pv SELECT LEFT(v.Name, 25) AS Vendor, LEFT(p.Name, 25) AS 'Product name', The LEFT and CASE functions customize the appearance of the result set. The EXECUTE AS CALLER clause is removed and the body of the procedure is modified to return only those vendors that supply the specified product. In the Valuefield, type 018.018 is the ID for an organization (EMPEMPLOYEEDIM.ORGANIZATIONCODE)in the EMPEMPLOYEEDIM table. TheSpecify Parameter Values window opens. The example modifies the uspVendorAllInfo procedure. To run the stored procedure: In the Data Project Explorer view, right-click the storedprocedure, and select Run. Use ALTER instead.Ĭopy and paste the following example into the query editor. ON v.BusinessEntityID = pv.BusinessEntityIDĭropping and recreating an existing stored procedure removes permissions that have been explicitly granted to the stored procedure. SELECT v.Name AS Vendor, p.Name AS 'Product name', IF OBJECT_ID ( 'pVendorAllInfo', 'P' ) IS NOT NULLĭROP PROCEDURE pVendorAllInfo ĬREATE PROCEDURE pVendorAllInfo The example creates the uspVendorAllInfo procedure, which returns the names of all the vendors in the Adventure Works Cycles database, the products they supply, their credit ratings, and their availability. For this example, select the AdventureWorks2022 database.Ĭopy and paste the following example into the query editor. Or, from the tool bar, select the database from the list of available databases. To modify a procedure using T-SQL commands:Įxpand Databases, expand the database in which the procedure belongs. For more information, see SQL Injection Use Transact-SQL Never execute a command constructed from unvalidated user input. Do not concatenate user input before you validate it. Accept the file name or replace it with a new name, and then select Save. To save the updated procedure definition as a Transact-SQL script, on the File menu, select Save As. To save the modifications to the procedure definition, on the Query menu, select Execute. To test the syntax, on the Query menu, select Parse. In Object Explorer, connect to an instance of Database Engine and then expand that instance.Įxpand Databases, expand the database in which the procedure belongs, and then expand Programmability.Įxpand Stored Procedures, right-click the procedure to modify, and then select Modify. To modify a procedure in SQL Server Management Studio: Requires ALTER PROCEDURE permission on the procedure. If the previous procedure definition was created using WITH ENCRYPTION or WITH RECOMPILE, these options are enabled only if they are included in the ALTER PROCEDURE statement. Transact-SQL stored procedures cannot be modified to be CLR stored procedures and vice versa.
