SQL 2012 :: Check Query Execution Plan Of A Store Procedure From Create Script?
Jun 17, 2015
Is it possible to check query execution plan of a store procedure from create script (before creating it)?
Basically the developers want to know how a newly developed procedure will perform in production environment. Now, I don't want to create it in production for just checking the execution plan. However they've provided SQL script for the procedure. Now wondering is there any way to look at the execution plan for this procedure from the script provided?
We have got a query for fine tuning and it is using lot of CTE ,how can i check the execution plan of that?
CREATE VIEW Mercy AS with ADR as ( SELECT urpx.RoleID , urx.UserID FROM [DBA].dbo.URPX WITH ( NOLOCK ) INNER JOIN [DBA].dbo.URX WITH ( NOLOCK ) ON urpx.RoleID = urx.RoleID WHERE PermissionID = '1' ), SDR as (
-- Collect the roles that a configured with Sales Team Create permission
-- This will include Sales Director , Suite Admin,
SELECT urpx.RoleID FROM [DBA].dbo.URPX WITH ( NOLOCK ) INNER JOIN [DBA].dbo.URX WITH ( NOLOCK ) ON urpx.RoleID = urx.RoleID LEFT OUTER JOIN ADR ON ADR.UserID = urx.UserID WHERE ADR.RoleID IS NULL AND PermissionID='2' )
i have a few stored procedures called by an application that i would like to create execution plans for every time they are run. is there a way to do this? or are execution plans only done through the Sql Server Query Editor? these queries make comparisons between a temp table and a master table and setting up the data for the tables is time consuming. so id like to automate it by setting the store procedure to create the execution plan at runtime.
know if there is any way out to run execution plan for parameterized queries?
As application is sending queries which are mostly parameterized in nature and values being used are very robust in nature, So i can not even make a guess.

I want to find out more information about the execution plan. I saw Parallelism (Gather Streams) in the excution plan. In what situation we can see this icon?If in case if we need to avoid how can we avoid this?
I have an execution plan that is huge, the pdf it generates if I print it is over 1000 pages. Is there a way to change the graphical plan into a table, so I can sort the %, and find the items that are taking the longest?
Need table has clusted index on needid column and NeedCategory have composite clustered index on needid and categoryid.
Now take a look on following query and execution plan for the query.
SELECT N.NeedId,N.NeedName,N.ProviderName FROM dbo.Need N JOIN dbo.NeedCategory NC ON nc.NeedId = n.NeedId WHERE IsActive=1 AND CategoryId= 2 ORDER BY NeedName
* Clustered index scan on need table is happens for Isactive= 1.
* Clustered index scan on needcategory table is happens for CategoryId=2
My question is,
1. Why scan happens before the join occurs? if it happens after join then the filter would be lighter. Even if optimizer chooses the scan to execute first.
2. Is there any chance to rearrange the execution plan manually?
I'm in the process of trying to optimize a stored procedure with many queries. The execution plan provides a missing non-clustered index on nearly every query, and they're all fairly similar. The only real difference between them are what's in the INCLUDE statement. The two key columns are listed in every missing index. Let's say each query is approximately 5% of the total batch and 90% of the queries all fall into the category I listed above. How should I go about creating the missing indexes? Create all of the missing indexes or create one generic one that has all the INCLUDE columns? Create a minimal index with just a few of the common INCLUDE columns?
Here's an example of what I'm talking about with the missing indexes:
/* USE [DB] GO CREATE NONCLUSTERED INDEX [<Name of Missing Index, sysname,>] ON [dbo].[TABLE_1] ([COLUMN_A],[COLUMN_B]) INCLUDE ([C4ABCD],[C4ARTX],[C4ASTX],[C4ADNB],[C4AFNB],[C4BKVA]) GO */ /*
The Query Processor estimates that implementing the following index could improve the query cost by 99.9044%.
*/ /* USE [DB] GO CREATE NONCLUSTERED INDEX [<Name of Missing Index, sysname,>] ON [dbo].[TABLE_1] ([COLUMN_A],[COLUMN_B]) INCLUDE ([C4ARTX],[C4ASTX],[C4ADNB],[C4CZST]) GO */
/*
The Query Processor estimates that implementing the following index could improve the query cost by 99.5418%.
*/ /* USE [DB] GO CREATE NONCLUSTERED INDEX [<Name of Missing Index, sysname,>] ON [dbo].[TABLE_1] ([COLUMN_A],[COLUMN_B]) INCLUDE ([C4ABCD],[C4ARTX],[C4ASTX],[C4ADNB],[C4AFNB],[C4BKVA]) GO */
I'm new to using SQL Server. I've been asked to optimize a series of scripts that queries over 4 millions records. I've managed to add indexes and remove a cursor, which increased performance. Now when I run the execution plan, the only query that cost is a DELETE statement from the main table. It shows a SORT which cost 71%. The table has 2 columns and a unique index. Here is the current index:
ALTER TABLE [dbo].[Qry] ADD CONSTRAINT [Qry_PK] PRIMARY KEY NONCLUSTERED ( [QryNum] ASC, [ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = ON, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] GO
Question: Will the SORT affect the overall performance? If so, is there anything I should change within the index that would speed up my query?
I'm trying to get the execution plan for a single stored procedurefrom Profiler. Now, I've isolated the procedure but I get allexecution plans. Any ideas on how to connect the SPIDs so that I onlyget the execution plan for the procedure I'm watching and not thewhole of the server?
I wanted to know whether we have an execution plan enabled in SQL 6.5 as we have it in SQL 7.0 and SQL 2000 . I.e when we execute a query and if we enable ' show execution plan 'then it creates a map and shows the vital statistics . If that is available on SQL 6.5 then i am missing that tool .
How can i have it installed on my SQL 6.5 server ??
if t-sql query is perfectly run in development and when I execute in production at that time I want to use execution plan which is in development . so how I can do using cache? I know about hint we can use hint USE_PLANE. but I want to do with cache .
This is probably a very stupid question. I have been out of the SQL Server arena for awhile and am now getting re acclimated. It was my understanding that using execution plan in query analyzer does not really execute the query against the query's database tables. Is this right? Tom.
I am developing an application (VB) that should present a query estimated execution plan.
Using the SQL Server Management Studio, I should execute the following commands to see the query's estimated execution plan:
SET SHOWPLAN_XML ON
go
MyQuery go
SET SHOWPLAN_XML OFF
go
The query is not executed. The result is the query execution plan.
In my application, I call Connection.Execute to execute the 'SET SHOWPLAN_XML ON'. Then, I use a Resultset submit the query. The query is executed and the execution plan is not returned.
The benefit of the actual execution plan is that you can see the actual number of rows passing through each step - compared to the estimated number of rows.But what about the "cost percentages" ?I believe I've read somewhere that these percentages is still just an estimate and is not based on the real execution.Does anyone know this and preferable have a link to something that documents it?Thanks
I have a store Procedure modify structTable but check syntax is error !
Please help me ? -------------------------------------------------------------------------------------------------------------------- IF EXISTS(SELECT NAME FROM SYSOBJECTS WHERE NAME ='MODISTRCTTABLE ' AND TYPE='P') BEGIN DROP PROCEDURE MODISTRUCT_TABLE END GO
CREATE PROCEDURE MODISTRUCT_TABLE @TABLE_NAME VARCHAR(60), @COLUMN_NAME VARCHAR(60), @COLUMN_TYPE VARCHAR(60), @COLUMN_SIZE INT(10) AS BEGIN IF EXISTS (SELECT @COLUMN_NAME FROM syscolumns) BEGIN ALTER TABLE @TABLE_NAME ALTER @COLUMN_NAME + ' ' + @COLUMN_TYPE+'('+ @COLUMN_SIZE +')' END ELSE BEGIN ALTER TABLE @TABLE_NAME ADD @COLUMN_NAME + ' ' + @COLUMN_TYPE+'('+ @COLUMN_SIZE +')' END END
I have SQL 7.0 SP2 on NT 4.0 SP5. My database is 180GIG. 23 Tables. It has been up and running for 2 years without any problems. All of a sudden my queries have started taking a long time to run. The optimizer has decided that table scans are better than indexes. If I use query hints they work just fine, but I can't modify all of our code to make these changes.
This is happening on all tables. Records counts are the in the same range they have always been.
Statistics and indexes are all fine and current. Have dropped and rebuilt both.
I am trying to tune a very long running query (18 minutes on an Axim X51, 8secs on my laptop), but I can't get the query plan file that is generated on the device to load in the Sql Server Management Studio. I am using the Sql Everywhere CTP on the device, and version 9.00.2047 of the management studio shell.
FWIW, when I try to create the execution plan by running the same query on a .sdf file local on my laptop, I get a similar error trying to view the query plan.
Apart from the query plan issues, it would appear (just from the query execution time) that the indexes defined on the sdf file are not being used when executing the query on the device, but are being used when executing the query on the laptop. This is pure SWAG on my part, though.
I can't figure out how to attach a file to the post, unfortunately.
Hi,I have a question about estimated query execution plans that aregenerated in QA of MSSQL.If I point at an icon/physical operator in the estimated QEP, it showsmesome statistics about the operator.Is there a way to retrieve these statistics through a query, i.e., canthese statistics be available to the user?Also, is there a way to generate these statistics on my own?thanks in advance-TC.
Hi All,I'm a relative newbie to SQL Server, so please forgive me if this is adaft question...When I set "Show Execution Plan" on in Query Analyzer, and execute a(fairly complex) sproc, I note that a particular query is reported ashaving a query cost of "71% relative to the batch" - however, this isnowhere near the slowest executing query in the batch - other querieswhich take over twice as long are reported as having costs in theorder of a few percent each.Am I misreading the execution plan? Note that I'm looking at thegraphical plan, and am not reading the 'estimated' plan - I'm usingthe one generated from executing the sproc. My expectation was thatthis would be based on the execution times of the queries within thesproc, however, this does not appear to be the case. (Note - Idetermined execution times from PRINT statements, using GETDATE() todetermine the current time, down to milliseconds).Any feedback would be of great assistance... I may well have tochange the way I approach optimizing queries based on these findings.Thanks,LemonSmasher.
Does anyone know if it is possible to access the execution plan results programmatically through a stored procedure or .NET assembly? I have the code sample
SET SHOWPLAN_XML ON; query... SET SHOWPLAN_XML OFF;
but it can only be run from the interface. I have tried a couple of solutions including dynamic sql to try to capture the results in a variable or file with no luck.
Does anyone know of a way to programmatically capture this information? We are doing some research with distributed query processing of dynamically generated queries using multiple processing nodes, and it would be helpful to know an estimate of how large the query is before sending it away to be processed.
I have looked at the dm_exec_query_stats view; but it can only be run on a query that has already been executed. I need to know the execution plan before the query is executed. If there is a way to get a query to show up in this view without being executed, then that would work as well.
Dear friends,I have a problem with a simple select statement and I don't know why it is happening.I have 2 tables, Fees and FeesDataRoles. Fees presents all the fees and FeesDataRole is a middle table between Fees and Roles table. So each fee can have multiple Roles and a Role can have many Fees.Now I have a select statement:Select *From Fees Inner Join FeesDataRoles ON Fees.FeeID = FeesDataRoles.FeeIDWhere (FeesDataRoles.DataRoleID = @DataRoleID) AND (FeesDataRoles.RecordStatus = 1 ) AND (FeesDataRoles.ValidFrom >= getdate() ) AND ( FeesDataRoles.ValidTo <= getdate() OR FeesDataRoles.ValidTo is null)Now it shouldn't take that long to execute this procedure but surprisingly sometimes when I insert a value to the table and then execute this store procedure it does now show the data just added. Very strange.....!!!!I ran the procedure 5 times after inserting an item and nearly 1 out of 5 does not return the right result righ. ( It does not include the recently inserted rows)Anyone have any idea....?I used Tuning Advisor, no sugestion. I change the clustered index in FeesDataRoles from FeesDataRoleID(the primary key of the table) to DataRoleID to increase the performance, still it happens sometimes.Is my Where clause so costly that cause this problem.Please help. I really appreciate your help.Regards,Mehdi
HI I have a problem related Store Procedure, that i am trying to extact a value from Database (Like FirstName,LastName,Email Address) through Store Procedure and Display it in the DropDownList(Like: FirstName LastName ,(xyz@xyz.com)) , and this is working correctly. Now i try to check the value at the same time if it is NULL value in the Database then pass EmptyString to the DropDownList Like ("" "" ,(xyz@xyz.com)) how i can do that in the store procedure. Comments will be appreciated.
I have reservation database, suppose somebody reserved a resource on 10/12/2006 from 9:00am to 12pm. If anybody else want to reserve the same resource from 10am to 3pm. It will not let them reserver. I would like to check a range in store procedure. Is there has any function to check range in easy way? Many thanks.
I want to create a check constraint on a table but the constraint values depend upon another table column as well, now one possible way is to create a function to check the column value. But I don’t want to use the function.
Can I do this in a view if so then how can I achieve this.
I am not familiar with the Store Procedure, so just want to know how to create the store procedure? For example, i want to write a store procedure for Login validation to check whether the username and password is correct. So what should i do???
