Same Statement Executes 10 Times Faster As Raw Sql In Query Analyzer Then In A Stored Proc
Aug 15, 2007
Hi,
I apologize for the long post but I am trying to give as much information as I can about the steps I've taken to troubleshoot this.
We have a stored procedure that builds a sql statement and executes it using the Execute command. When I execute the stored procedure through query analyzer it takes close to 5 seconds to execute. When I print out the exact same statement and execute it directly in query analyzer as "raw sql", it takes 0.5 seconds - meaning it takes 10 times longer for the code to execute in the stored proc. I altered the stored proc to execute the printed sql instead of building but it still takes the full 5 seconds and there were no changes in the execution plan. This makes me confident that the issue is not caused by the dynamic sql. I've used with recompile to make sure that the stored procedure caches the most recent execution plan. When I compare the execution plans, the stored proc uses a nested loop whereas the raw sql statement uses a hash join. Seeing that, I added the hash hint to the stored proc and doing so brought down the execution time down from 5 secs to 2 secs but still the raw sql statement uses a clustered index whereas the stored proc uses a non-clustered index and that makes the statement 4 times slower. This proves how efficient clustered indexes are over non-clustered ones, but it doesn't help me since, as far as I know, I can't force SQL Server to use the clustered index.
Does anyone know why sql server is generating such an inefficient execution plan for the stored proc compared to the execution plan that it generates when executing the raw sql statement? The only thing I can think of is that some stats are not updated and that somehow throws off the stored proc. But then again, shouldn't it affect the raw sql statement?
Thank you,
Michael Tzoanos

I'm currently updating one of our web sites and have encountered astrange problem. The page that is giving me the problem is written inASP and hits a SQL 2K DB. When I click submit I have 4 procs thatneed to be executed. I always get a sql server timeout error. Iopened up Profiler and traced the events. The page hangs on the lastproc called which is basically a select * where id = @id. If I runthe same proc that hangs in query analyzer, literally copy fromprofiler into query analyzer the proc runs no problem but when I'mhitting it from the web it hangs. The proc takes in 1 argument whichI see when I view the trace in profiler. The id getting passed to theproc is correct. I don't think this is a web problem because the COMobject that runs the last 2 procs works on other productionapplications with no problems. I was wondering if anyone has anysuggestions. I'm not a dba but would like to know what the problem isfor future reference. I pasted the proc below just for the hell ofit. FYI, I changed the name of the proc, table and columns forsecurity purposes.CREATE PROCEDURE [dbo].[spName]@TNum integerASSELECT M.*FROM tblName MWHERE (M.[idColumn] = @TNum)GOThanks in advance,Bob

I have an ASP that has been working fine for several months, but itsuddenly broke. I wonder if windows update has installed some securitypatch that is causing it.The problem is that I am calling a stored procedure via an ASP(classic, not .NET) , but nothing happens. The procedure doesn't work,and I don't get any error messages.I've tried dropping and re-creating the user and permissions, to noavail. If it was a permissions problem, there would be an errormessage. I trace the calls in Profiler, and it has no complaints. Thedatabase is getting the stored proc call.I finally got it to work again, but this is not a viable solution forour production environment:1. response.write the SQL call to the stored procedure from the ASPand copy the text to the clipboard.2. log in to QueryAnalyzer using the same user as used by the ASP.3. paste and run the SQL call to the stored proc in query analyzer.After I have done this, it not only works in Query Analyzer, but thenthe ASP works too. It continues to work, even after I reboot themachine. This is truly bizzare and has us stumped. My hunch is thatwindows update installed something that has created this issue, but Ihave not been able to track it down.

Yesterday i face a strange SQL Server 2000 behaviour :-(
I had a query that was wrapped inside a stored procedure, as usual.
Suddenly, the stored procedure execution time raised from 9 secs to 80.
So to understand where the problem was i cut and pasted the sp body's into a new query analyzer window an then executed it again. Speed back to 9 secs.
Tried stored procedure again, and speed again set to 80 secs.
Tried to recompile sp. Nothing. Tried to restart SQL Server. Nothing. Tried to DROP & RE-CREATE sp. Done! Speed again at 9 secs.
My collegue asked me "why?", but i had no words. :confused: Do you have any explanation?

Hi,
In SQL 2000, to debug a stored proc I would launch QA, right click and hit debug.
How do I accomplish this with SQL 2005. I can't see that it came with QA.
Thank you,
Steve

Hello,everyone!!
There is a query which when executed in the grid mode(ctrl+d) takes approx 0.02 seconds(about 21,000
rows) But when I execute in the text mode, it takes about 0.40 seconds!!
Why is this difference?
Also, when the records from this table are read from a VB application, they are equally slow (as in the text mode!)
Why is it so slow on the text mode & relatively faster in the grid mode?
Has anyone got any idea on ‘Firehose’ style cursor ?(which may speed up access of data in the VB application)
Rgds,
Adie

Anyone got any alternatives to the SQL Statement below that would make it run a bit faster:

AND tbl_SurgerySlot.ExtractDate = @ExtractDate
AND tbl_SurgerySlot.StartTime BETWEEN @DateFrom AND @DateTo
AND tbl_SurgerySlotDescription.NormalBookable = 1
AND tbl_SurgerySlot.SurgerySlotKey NOT IN(
SELECT tbl_Appointment.SurgerySlotKey
FROM tbl_Appointment
WHERE tbl_Appointment.ExtractDate = @ExtractDate
AND tbl_Appointment.Deleted = 0

We are having a problem with Query Analyzer not connecting to SQL Server anymore. Sometimes it will, sometimes it won't. Sometimes when it does, then you click on the databases drop-down, it may take a long time to return. Likewise, it may take a long time to open the object browser, or it may open without the database info but with just the "Common Objects" info.
All of this used to work just fine.

I am running a DTS Package.I have a temp table with 1494 records. I am inserting a 'Y' or'N'into a temp table #HasClaims.The TempTable name with the Provider Id's(PRPR_ID) is#TempFACETSNODupesThe @identityID is an identity field counting back from 1494 to 1I count back from the Max value of the identityid (1494) in the Whileloop until I get through all the records. The idea is to check for theexistance of a claims and authorization record and put a 'Y' or 'N'record in the temptable #HasClaims.This is running in the Execute SQL Task object of the DTS Package.The Package runs successfully but only inserts 200 rows into the newtemp table. There should be a row for each provider. Each time itruns, the number of rows it returns is different. Sometimes it is 205,then 185, then 210, before it completes the DTS package.Has anyone run into While looping problems within an Execute SQL taskin a DTS package(SQL 2000)like this--------------------------------------------------------------SELECT @identityID = MAX(IDENTITYID) FROM #TempFACETSNODupesWhile @identityID >= 1BEGIN@PRPRID is the placeholder for the PRPR_ID (Provider)SELECT @PRPRID = PRPR_ID FROM #TempFACETSNODupes WHERE IDENTITYID =@identityIDIF exists( SELECT CLCL_ID FROM dbo.CMC_CLCL_CLAIM CLCL WHERECLCL.PRPR_ID = @PRPRID)BEGININSERT INTO #HasClaims (PRPR_ID, HasClaims, IdentityID)VALUES( @PRPRID, 'Y', @identityID)ENDELSE INSERT INTO #HasClaims (PRPR_ID, HasClaims, IdentityID)VALUES( @PRPRID, 'N', @identityID)------------------------------------------------------------SELECT @identityID = @identityID - 1END

I have basic SQL query that returns a one column result set. For each row returned in this result set, I need to pass the value in the column to a stored procedure and get back a result set.
I have 2 solutions, neither of which are very elegant. I'm hoping someone can point me in a better direction.
Solution 1:
Use a cursor. The cons here, are the SP returns a result set on each pass which generates multiple result sets overall. If there is a way to combine these result sets, I think this solution might work.
Solution 2:
Use a temp table or table variable.
The cons here are, if the schema of the result set returned from the stored procedure changes, the table variable will have to change to accommodate it. This is a dependency I'd rather not create.
Any help is very much appreciated.

We have a sort of complex user structure in the sense that depending on the type of user the data resides in different tables. Therefor I needed a stored procedure that finds out what table to look for a certain column in. Below is such a stored procedure and it works like it should but my problem is that I don't know how to retrieve the result (which should be a string so can't use RETURN).
I've tried using an OUTPUT variable but since I just run EXEC (@statement) in the end I can't really set an output variable the common way (as in EXEC @outputVariable = PMC_User_GetUserValue(arg1, arg2..)) or can I?
I have also tried to use SELECT to catch the result somehow but no luck and Google didn't help either so now I'm hoping for one of you... Notice that you don't have to bother about much of the code except for the end of it where I want it to return somehow or figure out a way to call this stored procedure and retrieve the result.
Thanks in advance

I am trying to troubleshoot some high activity on one of my SQL Servers, and when I run sp_who2 'active' I get the current activity, and spid number. I check under Process Info for the spid, and wHEN i double click the spid, I get part of the sql statement run by that trouble spid. Is there a way to get the whole sql statement in Query Analyzer without running SQL Profiler. Thanks in advance for any help.

Hi All,
What i'm trying to do is build a dynamic query where the like clause is the variable bit of the query. What I've done is to create 4 varchar variables of length1000, and a variable to hold the result of the concatenated variables, which is defined as length of 4000. I've checked the length of the resultant query and its comes in at arount the 450 charcter lenght, but when I run the stored proc it truncates the @varfull around the point of the first % sign.
I've tried various ways to create this query and it always truncated around the point of the % sign.
Am I doing this right? can anyone point me in the right direction on how to do this with a sql statement, it works fine for text strings!
Here's part of the code, I create the content of @var3 in a loop based on a string of words passed into the stored proc.
Thanks for any help on this!

Hi all,
I have a problem with a stored procedure that executes properly when running it in Query Analyzer. When I call the SP from an ASP.NET application, it doesn't seem to run properly. I have verified that the parameter values are correct, but there is one update command that does not update any rows when it executes although it should. I tried stepping through the SP from within Visual Studio and it still does not work properly even though all parameters have the correct values.
Why would a SP execute properly when used in QA but not when an application executes it?

I am using SQL sever 2k and C#.
There is a stored-procedure that it has multiple select statements as returned result set. How can I use SqlCommand.ExecuteReader to get all result set?
What if the multiple select statements is " FOR XML", how can I set all xml using ExecuteXmlReader?
I tried to use ExecuteReader or ExecuteXmlReader, but seems that I can only get back the result set of the first select statement, all others are messed up.
stored procedure example: NorthWind database:
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS ON
GO
Create PROCEDURE dbo.getShippersAndEmployeesXML
AS
select * from Shippers for xml auto, elements
select * from Employees for xml auto, elements
RETURN @@ERROR
GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
C# code example:
//set connect, build sqlcommand etc
XmlTextReader reader = (XmlTextReader)command.ExecuteXmlReader();
StringBuilder sb = new StringBuilder();
while(reader.Read()) sb.Append(reader.ReadOuterXml());
Thanks for your help.

Hi All!
I know this must be a very silly question but, what is the PLSQL string I have to use to delete a stored procedure in a database? Essentially I have to remove a stored procedure that comes from a database backup every night because it belongs to a user and that user has to be recreated in the new SQL Server 2000. Simply put:
1. Production database comes into test database
2. Remove copy of stored procedure since it can not be set to dbo user because there is another copy with the same name that belongs to dbo.
3. Remove user
4. Add user (this one brings login name since the restored one didn't)
5. Have a nice day
I've got everything except removing the stored procedure so I will really appreciate the help.
Thank you all!

If I run this statement in Query Analyzer, it properly returns 1for my testing table. But if I put the statement into a storedprocedure, the stored procedure returns NULL. What am I doingwrong? I suspect it may be related to how I defined the parametersfor the stored procedure. Perhaps my definition of TableName andColumnName don't match what COLUMNPROPERTY and OBJECT_ID expect toreceive, but I don't know where to look for the function declarationsfor those. Any pointers would be appreciated.Select statement:SELECT COLUMNPROPERTY(OBJECT_ID('Table1'), 'TestID', 'IsIdentity') ASIsIdentityTable definition:CREATE TABLE [dbo].[Table1] ([TestID] [numeric](18, 0) IDENTITY (1, 1) NOT NULL ,[Description] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL) ON [PRIMARY]Stored Procedure definition:CREATE PROCEDURE spTest(@TableName varchar,@ColumnName varchar)AS SELECT COLUMNPROPERTY(OBJECT_ID(@TableName), @ColumnName,'IsIdentity') AS IsIdentity

HI,
I have an interesting situation. I have created a stored procedure which has a select union query and it accepts some parameters. When I execute this procedure it takes 8 minutes. When I copy the script in stored procedure and run it directly in Query Analyzer it takes 2 1/2 minutes?? Same numbers of rows are returned either way in the result set with about 13,000.
I cannot figure this out and it is almost the same thing except that in Query Analyzer I declare the parameters variables and its values?
Any feedback would be appreciated!
Thanks in advance...

Hi. I am having a problem using DTSRun in a stored procedure or in query analyzer.
My DTS package truncates a table and then imports data from an Excel spreadsheet into the table.
The DTS package runs fine if I run it manually on Enterprise Manager or if I use DTSRun in a command prompt.
However when I try to run the package in a stored procedure or in query analyzer as follows:
ie Exec master..xp_cmdshell 'DTSRUN /SSQL SERVER /NPackageName /Uuserid /Ppassword'
The package does not return an error but it does not actually import any data from the Excel spreadsheet. It is able to truncate the table without any problem.
I've tried all kinds of combination of using Windows user id that I know has access to the excel file instead of a sql login.
I've run Filemon on the excel file and it seems like DTS is not accessing the file when I use the stored proc or query analyzer method.
If anyone could shed any light on this I would be most grateful. Thanks.
