I have a stored procedure that I want to test for performance , however, I cannot view the estimated query plan execution. I am not using any nested subqueries. Any ideas why the plan will not generate?
Thanks in advance!
When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.
1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?
<ParameterList>
<ColumnReference Column="@Measure" ParameterCompiledValue="'all'" />
</ParameterList>
</QueryPlan>
</StmtSimple>
2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?
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?
This post is related to SQL server 2000 and SQL Server 2005 alleditions.Many of my stored procedures create temporary tables in the code. Iwant to find a way to find the query plan for these procsRepro--***********************************use pubsgoCREATE PROCEDURE Test @percentage intASSET Nocount on--Create and load a temporary tableselect * into #Temp1 from titleauthor--Create second temporary tablecreate table #Temp2 ( au_id varchar(20), title_id varchar (20), au_ordint, rolaylityper int)--load the second temporary table from the first oneinsert into #Temp2 select * from #Temp1goset showplan_Text ONgoEXEC Test @percentage = 100GOset showplan_Text OFFgo**************************************I get the following errorServer: Msg 208, Level 16, State 1, Procedure Test, Line 10Invalid object name '#Temp2'.Server: Msg 208, Level 16, State 1, Procedure Test, Line 10Invalid object name '#Temp1'.I do understand what the error message means.

In the stored procedure I try to use the x: drive and that does not work. I have tried obtaining the \192.168.x.x address and that only works on some of my servers. All are running SQL 2000, some are using Win2K and Win2003. It does not seem to matter. One of them that is using Win2003 only fails occationally.
I notice when I do a
exec master..xp_cmdshell 'x:'
The system cannot find the drive specified.
Yet, when I go to the server there is an x drive.
I am using the sqlserv user to run the job and that use is an administrator on the local machine. This is a virtual machine. We add the X before the osql and drop it after the command finishes.
Any help would be appreciated. Thanks, dbmsql
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.

We have a debate in our team about embedded SQL vs. Stored Procs.
The argument is why use SP's if you can embed the SQL in the code and SQL2K will cache it on the fly?
I can't find any definitive information on pros and cons between the two methods.
If there are no major performance issues, or gotchas, I guess it comes down to developer preference.
SP Pros:
- Great SQL support in VS.NET (dev, debug, integration)
- Seperation of database specific code from middle tier.
- Less lines of code in middle tier
- VS.NET support for .xsd dataset definitions.
- Logic closer to data for more demanding processes.
Embedded SQL Pros:
- Less artifacts for version control
- Better encapsulation of logic
Any info would be appreciated.
thanks

Is only one plan is kept for one query in plan cache?
i heard generally hash is created for a query and plan is search with this hash.
Has anyone encountered cases in which a proc executed by DTS has the following behavior:
1) underperforms the same proc when executed in DTS as opposed to SQL Server Managemet Studio
2) underperforms an ad-hoc version of the same query (UPDATE) executed in SQL Server Managemet Studio
What could explain this?
Obviously,
All three scenarios are executed against the same database and hit the exact same tables and indices.
Query plans show that one step, a Clustered Index Seek, consumes most of the resources (57%) and for that the estimated rows = 1 and actual rows is 10 of 1000's time higher. (~ 23000).
The DTS execution effectively never finishes even after many hours (10+)
The Stored procedure execution will finish in 6 minutes (executed after the update ad-hoc query)
The Update ad-hoc query will finish in 2 minutes
I am working on tuning the procedure cache hit ratio for my server. We haveadded 4 Gb of memory to the server, which has helped. In addition, I have runthe DBCC FREEPROCACHE, which helped for a couple of days to get the hit ratioup to about 84% (from 68%).When I use the performance monitor on the server and look at SQL Server CacheManager:Buffer Hit Ratio, I see that the Prepared SQL Plan is around 97%, butthe Procedure Plan hit ratio is down around 55%. I've done some research ondifferent tuning techniques, but can't seem to find 1. a clear definition ofthe difference between the prepared sql plan and the procedure plan and 2.other than adding memory and running dbcc freeprocache, how can I get theprocedure plan cache raised? I do know that there are some procedures thatneed to be modified to be called fully qualified (e.g. exec dbo.sp_###instead of exec sp_###), but I don't think that those will increase theprocedure plan by 30% or more.Any insight you can give would be greatly appreciated.Thanks,Michael--Message posted via SQLMonster.comhttp://www.sqlmonster.com/Uwe/Forum...eneral/200511/1
View 1 Replies View RelatedFor some reason, I run a stored procedure in Query Analyzer and it works fine. When I run the very same procedure in MS access by clicking on its link I have to run it twice. The first run gives me the message that the stored procedure ran correctly but returned no records. The second run gives me the correct number of records but I have to run it twice. I am running month-to-month data. The first run is Jan thru March. Jan and Feb have no records so I run three months on the first set. The ensuing runs are individual months from April onward. The output is correct but any ideas on why I have to do it twice in Access? I am a bit new to stored procedures but my supervisor assures me that it should be exactly the same.

Seems like I'm stealing all the threads here, : But I need to learn :) I have a StoredProcedure that needs to return values that other StoredProcedures return.Rather than have my DataAccess layer access the DB multiple times, I would like to call One stored Procedure, and have that stored procedure call the others to get the information I need. I think this way would be more efficient than accessing the DB multiple times. One of my SP is:SELECT I.ItemDetailID, I.ItemDetailStatusID, I.ItemDetailTypeID, I.Archived, I.Expired, I.ExpireDate, I.Deleted, S.Name AS 'StatusName', S.ItemDetailStatusID, S.InProgress as 'StatusInProgress', S.Color AS 'StatusColor',T.[Name] AS 'TypeName', T.Prefix, T.Name AS 'ItemDetailTypeName', T.ItemDetailTypeID FROM [Item].ItemDetails I INNER JOIN Item.ItemDetailStatus S ON I.ItemDetailStatusID = S.ItemDetailStatusID INNER JOIN [Item].ItemDetailTypes T ON I.ItemDetailTypeID = T.ItemDetailTypeID However, I already have StoredProcedures that return the exact same data from the ItemDetailStatus table and ItemDetailTypes table.Would it be better to do it above, and have more code to change when a new column/field is added, or more checks, or do something like:(This is not propper SQL) SELECT I.ItemDetailID, I.ItemDetailStatusID, I.ItemDetailTypeID, I.Archived, I.Expired, I.ExpireDate, I.Deleted, EXEC [Item].ItemDetailStatusInfo I.ItemDetailStatusID, EXEC [Item].ItemDetailTypeInfo I.ItemDetailTypeID FROM [Item].ItemDetails IOr something like that... Any thoughts?

Hi,
Is there any way to look at behind-the-scene SQL query that gets generated by SSRS engine to pull the data out of the data source (particularly SQL Server).
So far, I only know that you can see the query generated by semantic query engine by changing trace option in configuration file.
Thanks and Regards,

I want to turn this SQL into a stored proc; there are currently about 8 parameters that I want to pass into it. The field value for each will be either NULL or a positive integer, and the paramater will be passed in as an integer.
If the passed parameter value is a positive integer then it should return all records where the corresponding field value matches that integer. If the passed parameter is 0, it should return all rows regardless of whether the field value is an integer or NULL.
And I can't for the life of me figure out how to do it. Do I need an IF statement in there or something?

There are times when I either compile a stored procedure, or right now as I am creating indexes on tables, when sp_who2 shows a SPID assigned to my name that I do not currently have opened in SSMS. When I check the statement with dbcc inputbuffer it shows a query hitting many of the system views. Earlier this week, someone tried killing one of these SPIDS and SQL Server generated a new SPID with the same type of query.

View 3 Replies View RelatedIn access, I can create a function that I can call in a query. It runs that function iteratively. Do I have the same ability with SQL server? Can I call a stored procedure WITHIN a query? I would like to be able to do something like:
Insert into tblOrders(spFirst_Name) Select {Call spUpperLower(tblClients.First_Name)} from tblClients Where ...
So basically, spUpperLower would run on every First Name Row in the result set.
Any help would be much appreciated.
Thanks,
Brad

Hi,
I have created an SQL query which returns the expected data. However, when I try to run it as a stored procedure, I get no rows returned.
(I assume I running the procedure correctly e.g. exec getNonDeployed RCN20047)
Code:
CREATE PROCEDURE getNonDeployed
@packageID text
AS
BEGIN
DECLARE @CollectionID VARCHAR(10)
DECLARE @Collections TABLE (CollectionID VARCHAR(10))
set @CollectionID = (SELECT
CollectionID
from ProgramOffers
where OfferID='@packageID');
WITH CollectionFull (SubCollectionID) AS
(
-- Create the anchor query. This establishes the starting
-- point
SELECT
SubCollectionID
from v_CollectToSubCollect a
where a.SubCollectionID=@CollectionID
UNION ALL
-- Create the recursive query. This query will be executed
-- until it returns no more rows
select
a.SubCollectionID
from v_CollectToSubCollect a
inner join CollectionFull b on b.SubCollectionID=a.ParentCollectionID
)
Insert Into @Collections
SELECT * FROM CollectionFull
select a.RuleName AS MACHINENAME, c.IPAddress0 as IPADDRESS
from v_CollectionRuleDirect a
inner join @Collections b on b.CollectionID=a.CollectionID
inner join v_GS_DEVICE_NETWORK c on c.ResourceID=a.ResourceID
where RuleName not in (select distinct a.MachineName as MACHINENAME
from v_StatusMessage a, v_StatMsgAttributes b, v_CollectionRuleDirect c, v_GS_DEVICE_NETWORK d, v_Collection e
where (a.RecordID=b.RecordID AND a.MachineName=c.RuleName and c.ResourceID=d.ResourceID and c.CollectionID=e.CollectionID)
AND b.AttributeValue IN ('@packageID'))

Hi All:
I have a situation where Im calling a stored procedure to insert some information.
When this information is inserted it is given a date/time stamp - say something in Aug.
There will be some corresponding records from the previous month already in the database that have some additional information that was manually added.
I need to query the corresponding records from the previous month and insert that info into the records that were just inserted.
the problem Im having is that i need to grab the most recent corresponding record. could be a day or a month prior to the one I just inserted. the also could be a record for months prior to that.
So how do i get the most recent corresponding record to my inserted record
Any suggestion on how to query this? and then pass the result to an udpate statement
Is there any way to do the following?select Max(FieldOne) From (spGetSomeData 100,'test' )Or do I need to define a view and have the stored proc use that view?The stored proc does some things with temp tables that would bedifficult to replicate with a view which is why I'm asking.

Hi,
is it better to use stored procedures or queries in terms of performance? I'm running application in ASP.NET, now the amount of data in the database is not very high, but I expect it'll grow, so I wonder about speed of queries etc.
Is it better to use SELECT ... FROM ... or to prepare stored procedure for such select? What about insert/update/delete?
thanks

Hello
I tried the Beta 1 of the service pack 1 to .net 3.5. If I try to add an entity (and try to save this), I get the Exception "No support for server-generated keys and server-generated values".
How can I add entities to my Sqlce- database?
I tried to give the id- column (primary key) in the database an identity, another time without identity, only primary key --> none of them worked. I always get the same error.
What do I have to change to make successfully a SaveChanges()?
Thanks for your help,
Gerald
