Stored Procedure Running Slow In ADO.NET

Jan 9, 2008

We have a stored procedure which is running fine on a SQL server 2000 from Query Analyzer. However, when we try to execute the same stored procedure from ADO.NET in an executable, the execution is hung or takes extremely long. Does anyone have any ideas or suggestions about how it could happen and how to fix. thanks

Stored Procedure Runs Slow Only Sometimes

Jan 6, 2006

When i execute a stored procedure it generally takes about half a second to run but sometimes it takes 20 to 30 seconds.  I am the only one using the server so I know it is not due to other traffic.  I have looked at Profiler and nothing looks out of the ordinary.  Another observation is that the slow ones are always near eachother.  I will have about 10 fast executions and then 3 slow ones and then back to fast ones.  Has anyone seen anything like this before?

How To Simplify This Slow Stored Procedure

Jan 20, 2005

Dear Reader(s),

Is there anyway to write the following stored procedure without the loop so that it goes much faster? :confused:

----------------------------------------------------------------------------
use MJ_ReportBase
go
if exists(select 1 from sysobjects where type='P' and name='sp_Periode')
begin
drop procedure sp_Periode
end
go
create procedure sp_Periode

, @stop int
as
declare @x int

set @x = 0
set @x=@start

delete from tbl_periode

while (@x>=@stop)
begin

-- ---
-- ---
-- Create table tbl_inout
if exists(select 1 from sysobjects where type='U' and name='tbl_inout')

order by

set @x=@x-1
end
go

print 'Klaar!'
--------------------------------------------------------------------------

What it does is determining the minimum entry time and the maximum exiting time per day of people going true the main entrance of a building.

Many thanks in advance.

Slow Execution Of Stored Procedure

Jun 29, 2007

Hello,

I have a big problem with slow execution of stored procedure in SQL Server 2005 but I really don't understand the reason. I have a database with large table (about 400 million rows) and simple stored procedure to get data from that table (one select statement to select time and value columns).

Strange thing is that if I call that stored procedure from .net application (native SqlDataProvider) it takes about 6 seconds to execute but if I call the same procedure with the same parameters from within SQL Server Management Studio it takes only 25 milliseconds to execute!

I've noticed that from .net, procedure is called with binary data and in Management Studio sql script is executed so I've copied/pasted the script from Management Studio to .net code and again the same thing happens (6 seconds from .net and 25ms from Management Studio). I traced executions with SQL Profiler and everything seems to be identical for both applications except it takes much longer time for .net application.

Both SQL Server Management Studio and .net application are on the same machine and SQL Server is on another.

This is the query that when executed in Management Studio takes 25ms:

EXEC [dbo].[GetRawData] @pcu = N'DV_ZERJ_HEV1',@tag = N'MJERENO',@from = N'20070629 07:00:00',@to = N'20070629 08:00:00'

This is the same query in .net application code that takes 6 seconds to execute:

sqlCommand = new SqlCommand("EXEC [dbo].[GetRawData] @pcu = N'DV_ZERJ_HEV1',@tag = N'MJERENO',@from = N'20070629 07:00:00',@to = N'20070629 08:00:00'",sqlConnection);
sqlReader = sqlCommand.ExecuteReader();

At first I thought that Management Studio somehow caches results but if I change parameters of stored procedure it always takes less than 30ms to execute.
I really don't understand this. Please, help!

Stored Procedure - Page Load Slow

Jul 25, 2006

Hi all,
I have a webpage with a Datagrid that populates using a table adapter from a Stored procedure that exists in my SQL Database...If I run the Stored procedure in SQL Directly then it takes 20 Secs to return all records...If I run the webpage then it takes just over 20 Secs..
Great you say..But If I have the sorting option set in ASP.net and I click on a column to sort then off the page goes for another 20 secs to sort the data..
Is there a better way to do what I am doing here that will speed up the page load..
Ie..the data is returned once and then sorted...
Is it Better / Quicker for me to create a table using the stored procedure and link to this from the website..Updating the table every couple of minutes ?
Any advice please ?
Ray..

Stored Procedure Run From ASP.NET Page Gets Very Slow Intermittently

Dec 5, 2006

I have developed a stored procedure that filters a view that is a union of several different tables. This provides status information for items across our warehouse management system. This system seems to work very well and normally processes results very quickly (< 3 seconds). However, occasionally (every few days) we begin to see timeouts on the query after 3 minutes of processing. I can watch this process in SQL Profiler and see that the query is timing out after 180 seconds, which is the timeout we have for the query within the DAL. When I copy the line from the SQL Profiler and execute it directly in SSMS, the query executes in less than 2 seconds. I first thought that somehow this had to do with execution plans, but when I try to reload the page again, which executes the query, it still times out. I did add a OPTION(KEEPFIXED PLAN) to the sproc, and that seemed to speed things up for the time, but I am not sure if this is even the problem and what the optimal solution would be. Any thoughts spring to mind?
 Thanks, Steve

Slow Stored Procedure - Easy Located But Wtf?

Jul 20, 2005

Hi,Plz, I need some info (SQL2000) :)A stored procedure is like this:"Select table1.id, table1.txt, (select table2.nr from table2 wheretable2.fk_table1=table1.id) as nr where table1.id<>10"The essence here is that "select table2.nr from table2 wheretable2.fk_table1=table1.id" returns either the integer in table2.nr, or NULLif there isnt a match. The whole sentence runs EXTREMELY slow...3-4 sec.What is wrong?"select table2.nr from table2 where table2.fk_table1=table1.id" runs quicklyoutside the stored procedure. The original sentence without the "nr" (Selecttable1.id, table1.txt where table1.id<>10) runs quickly too...But together it slows down dramatically..why? I should mention that thesub-query could return NULL if theres no match in table2...But i cant seewhy that should slow things down (remember - it runs fine outside the SP)?Thx,PipHans---Outgoing mail is certified Virus Free.Checked by AVG anti-virus system (http://www.grisoft.com).Version: 6.0.518 / Virus Database: 316 - Release Date: 11-09-2003

Problem Running Stored Procedure

Jan 3, 2005

Hi Guys & Gals

I'm having problems running a stored procedure, I'm getting an error that I don't understand. My procedure is this:

ALTER PROC sp_get_allowed_growers
@GrowerList varchar(500)
AS
BEGIN
SET NOCOUNT ON

DECLARE @SQL varchar(600)

SET @SQL =
'SELECT nu_code, nu_description, nu_master
FROM nursery WHERE nu_master IN (' + @GrowerList + ') ORDER BY nu_code ASC'

EXEC(@SQL)
END
GO


and the code I'm using to execute the procedure is this:


public DataSet GetGrowers(string Username)
{
System.Text.StringBuilder UserRoles = new System.Text.StringBuilder();
UsersDB ps = new UsersDB();
SqlDataReader dr = ps.GetRolesByUser(Username);
while(dr.Read())
{
UserRoles.Append(dr["RoleName"]+",");
}
UserRoles.Remove(UserRoles.Length-1,1);
//Create instance of Connection and Command objects
SqlConnection transloadConnection = new SqlConnection(ConfigurationSettings.AppSettings["connectionStringTARPS"]);
SqlDataAdapter transloadCommand = new SqlDataAdapter("sp_get_allowed_growers",transloadConnection);
//Create and fill the DataSet
SqlParameter paramList = new SqlParameter("@GrowerList",SqlDbType.VarChar);
paramList.Value = UserRoles.ToString();
transloadCommand.SelectCommand.Parameters.Add(paramList);
DataSet dsGrowers = new DataSet();
transloadCommand.Fill(dsGrowers);
return dsGrowers;

}



The UserRoles stringbuilder has an appropriate value when it is passed to the stored procedure. When I run the stored procedure in query analyser it runs just fine. However, when I step through the code above, I get the following error:


Line 1: Incorrect syntax near 'sp_get_allowed_growers'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: Line 1: Incorrect syntax near 'sp_get_allowed_growers'.



Anyone with any ideas would be very helpful...

Stored Procedure Only Part Running

Dec 10, 2001

I am calling a SQL Server 6.5 Stored Procedure from Access 2000 with the following code :-

Public Function CheckDigitCalc()

Dim conn As New ADODB.Connection
Dim cmd As New ADODB.Command

On Error GoTo TryAgain

conn.Open "DSN=WEB;uid=sa;pwd=;DATABASE=WEB;"
Set cmd.ActiveConnection = conn

cmd.CommandText = "SPtest2"
cmd.CommandType = adCmdStoredProc
cmd.Execute

MsgBox "Numbers created OK.", vbOKOnly

Exit Function

TryAgain:

MsgBox "Error occurred, see details below :-" & vbCrLf & vbCrLf & _
Err & vbCrLf & vbCrLf & _
Error & vbCrLf & vbCrLf, 48, "Error"

End Function

The MsgBox pops up indicating that the Stored Procedure has run, and there are no errors produced by either SQL Server or Access. However, when I inspect the results of the Stored Procedure, it has not processed all the records it should have. It appears to stop processing after between 6 and 11 records out of a total of 50. The wierd thing is that if I execute the procedure on the server manually, it works perfectly. HELP ME IF U CAN ! THANKS.

Running A Stored Procedure In Code

Apr 14, 2008

Hi,

I'm not sure if this is really the right place for this but it is related to my earlier post. Please do say if you think I should move it.

I created a Stored procedure which I want to run from Visual basic (I am using 2008 Express with SQL Sever 2005 Express)

I have looked through many post and the explaination of the sqlConection class on the msdn site but I am now just confussed.

Here is my SP


ALTER PROCEDURE uspSelectBarItemID2

(

@BarTabID INT,

@DrinkID INT,

@ReturnBarItemID INT OUTPUT

)

AS

BEGIN

SELECT @ReturnBarItemID = barItemID

FROM [Bar Items]

WHERE (BarTabID = @BarTabID) AND (DrinkID = @DrinkID)

END

In VB I want to pass in the BarTabID and DrinkID varibles (Which Im grabbing from in as int variables) to find BarItemID in the same table and return it as an int.

What I dont understand is do I have to create a unique connection to my database because it is already liked with a dataset to my project with a number of BindingSources and TableAdapters.

Is there an easier way, could I dispense with SP and just use SQL with the VB code, I did think the SP would be neater.

Cheers.

Running Stored Procedure Multiple Times

Jun 25, 2007

I’m binding the distinct values from each of 9 columns to 9 drop-down-lists using a stored procedure. The SP accepts two parameters, one of which is the column name. I’m using the code below, which is opening and closing the database connection 9 times. Is there a more efficient way of doing this?
newSqlCommand = New SqlCommand("getDistinctValues", newConn)newSqlCommand.CommandType = CommandType.StoredProcedure
Dim ownrParam As New SqlParameter("@owner_id", SqlDbType.Int)Dim colParam As New SqlParameter("@column_name", SqlDbType.VarChar)newSqlCommand.Parameters.Add(ownrParam)newSqlCommand.Parameters.Add(colParam)
ownrParam.Value = OwnerID
colParam.Value = "Make"newConn.Open()ddlMake.DataSource = newSqlCommand.ExecuteReader()ddlMake.DataTextField = "distinct_result"ddlMake.DataBind()newConn.Close()
colParam.Value = "Model"newConn.Open()ddlModel.DataSource = newSqlCommand.ExecuteReader()ddlModel.DataTextField = "distinct_result"ddlModel.DataBind()newConn.Close()
and so on for 9 columns…

Timeout Exception When Running Stored Procedure

Feb 4, 2008

Hi,
 I'm running a CLR stored procedure through my web using table adapters as follows:
res = BLL.contractRateAdviceAdapter.AutoGenCRA()    'with BLL being the business logic layer that hooks into the DAL containing the table adapters.
 The AutoGen stored procedure runs fine when executed directly from within Management Studio, but times out after 30 seconds when run from my application. It's quite a complex stored procedure and will often take longer than 30 seconds to complete.
The stored procedure contains a number of queries and updates which all run as a single transaction. The transaction is defined as follows:
----------------------------------------------------------------------------------------------------------------------
options.IsolationLevel = Transactions.IsolationLevel.ReadUncommittedoptions.Timeout = New TimeSpan(1, 0, 0)
Using scope As New TransactionScope(TransactionScopeOption.Required, options)
'Once we've opened this connection, we need to pass it through to just about every
'function so it can be used throughout. Opening and closing the same connection doesn't seem to work
'within a single transactionUsing conn As New SqlConnection("Context Connection=true")
conn.Open()
ProcessEffectedCRAs(dtTableInfo, arDateList, conn)
scope.Complete()
End Using
End Using
----------------------------------------------------------------------------------------------------------------------
As I said, the code encompassed within this transaction performs a number of database table operations, using the one connection. Each of these operations uses it's own instance of SQLCommand. For example:
----------------------------------------------------------------------------------------------------------------------Dim dt As DataTable
Dim strSQL As StringDim cmd As New SqlCommand
cmd.Connection = conn
cmd.CommandType = CommandType.Text
cmd.CommandTimeout = 0Dim rdr As SqlDataReaderstrSQL = "SELECT * FROM " & Table
cmd.CommandText = strSQL
rdr = cmd.ExecuteReader
SqlContext.Pipe.Send(rdr)
rdr.Close()
----------------------------------------------------------------------------------------------------------------------
Each instance of SQLCommand throughout the stored procedure specifies cmd.CommandTimeout = 0, which is supposed to be endless. And the fact that the stored procedure is successful when run directly from Management studio indicates to me that the stored procedure itself is fine. I also know from output messages that there is no issues with the database connection.
I've set the ASP.Net configuration properties in IIS accordingly.
Are there any other settings that I need to change?
Can I set a timeout property when I'm calling the stored procedure in the first place?
Any advice would be appreciated.
 
Thanks

I have a stored procedure that I need to run when the user clicks on our submit button.  I am using Visual Studio 2005 and thought I could use the SqlDataSOurce Control.  IS it possible to us the control or do I need to create a connection and call the stored procedure in the the button_click sub?
Thanks in advance

Error When Running A Stored Procedure From My Code

May 9, 2008

 Hi all,      I wonder if you can help me with this. Basically, Visual Web Developer doesn't like this part of my code despite the fact that the stored procedure has been created in MS SQL. It just won't accept that bold line in the code below and even when I comment it just to cheat, it still gives me an error about the Stored Procedure. Here's the line of code:          // Define data objects        SqlConnection conn;        SqlCommand comm;        // Initialize connection        string connectionString =            ConfigurationManager.ConnectionStrings[            "pay"].ConnectionString;        // Initialize connection        conn = new SqlConnection(connectionString);        // Create command         comm = new SqlCommand("UpdatePaymentDetails", conn);        //comm.CommandType = CommandType.StoredProcedure;        // Add command parameters        comm.Parameters.Add("PaymentID", System.Data.SqlDbType.Int);        comm.Parameters["PaymentID"].Value = paymentID;        comm.Parameters.Add("NewPayment", System.Data.SqlDbType.VarChar, 50);        comm.Parameters["NewPayment"].Value = newPayment;        comm.Parameters.Add("NewInvoice", System.Data.SqlDbType.VarChar, 50);        comm.Parameters["NewInvoice"].Value = newInvoice;        comm.Parameters.Add("NewAmount", System.Data.SqlDbType.Money);        comm.Parameters["NewAmount"].Value = newAmount;        comm.Parameters.Add("NewMargin", System.Data.SqlDbType.VarChar, 50);        comm.Parameters["NewMargin"].Value = newMargin;        comm.Parameters.Add("NewProfit", System.Data.SqlDbType.Money);        comm.Parameters["NewProfit"].Value = newProfit;        comm.Parameters.Add("NewEditDate", System.Data.SqlDbType.DateTime);        comm.Parameters["NewEditDate"].Value = newEditDate;        comm.Parameters.Add("NewQStatus", System.Data.SqlDbType.VarChar, 50);        comm.Parameters["NewQStatus"].Value = newQStatus;        comm.Parameters.Add("NewStatus", System.Data.SqlDbType.VarChar, 50);        comm.Parameters["NewStatus"].Value = newStatus;        // Enclose database code in Try-Catch-Finally        try        {            conn.Open();            comm.ExecuteNonQuery();        }

Stored Procedure To Fill Bridgetable Not Running

Oct 4, 2005

I have a table with information about a mobile account in one table, a table for mobile plans, and a table for planfeatures. Each mobile account is associated with a planid, and may be associated with any combination of the features associated with that plan. The plan features are stored in a bridgetable which contains 'invoicedate' (date stamped on the invoice in question), 'subaccountnumber' (the cell phone number), 'planid', and 'featureid'. I've tested the UpdateMobileFeature sp directly from the SQL Profiler--it works fine on it's own. I use a stored procedure to fill the mobile table (called from aspx page), and since I use three of the four columns written above for both the mobilesub and the mobilefeature tables, I tried just adding the parameter which holds the featureid's to the sp to update the mobilesub table. Then I call the UpdateMobileFeature sp from the updatemobile sp. (The code in mobilesub that is not calling UpdateMobileDetail works well). All seems to work fine--nothing crashes or anything, but nothing is being added to the mobilefeature table. Here is the code:CREATE procedure usp_updatemobile(     @InvoiceDate smalldatetime,    @SubaccountNumber varchar(50),    @PlanId int,   @FeatureList varchar(500) --added for UpdateMobileFeatures. In the form of a comma-seperated list, to imitate an array.  --***irrelevant parameters removed***--)
as
exec dbo.UpdateMobileFeature '@InvoiceDate','@SubaccountNumber','@PlanId','@FeatureList' --the apparently nonfunctional call
if exists (    //select for the mobile row in question )  Begin      //update row 
End
Else  Begin   //insert new row End
GOCREATE PROC dbo.UpdateMobileFeatures(  @InvoiceDate smalldatetime, @SubaccountNumber varchar(50),  @PlanID int, @FeatureList varchar(500))ASBEGIN SET NOCOUNT ON
 CREATE TABLE #TempList (  InvoiceDate smalldatetime,  SubaccountNumber varchar(50),  PlanID int,  FeatureID int     )
 DECLARE @FeatureID varchar(10), @Pos int  SET @FeatureList = LTRIM(RTRIM(@FeatureList))+ ',' SET @Pos = CHARINDEX(',', @FeatureList, 1)
 IF REPLACE(@FeatureList, ',', '') <> '' BEGIN  WHILE @Pos > 0  BEGIN   SET @FeatureID = LTRIM(RTRIM(LEFT(@FeatureList, @Pos - 1)))   IF @FeatureID <> ''   BEGIN    INSERT INTO #TempList (InvoiceDate, SubaccountNumber, PlanID, FeatureID)     VALUES (@InvoiceDate, @SubaccountNumber, @PlanID, CAST(@FeatureID AS int)) --Use Appropriate conversion   END   SET @FeatureList = RIGHT(@FeatureList, LEN(@FeatureList) - @Pos)   SET @Pos = CHARINDEX(',', @FeatureList, 1)
  END END 
 --SELECT o.FeatureID, CustomerID, EmployeeID, FeatureDate --FROM  dbo.Features AS o -- JOIN  -- #TempList t -- ON o.FeatureID = t.FeatureID
 
 Insert Into MobileFeatures Select InvoiceDate, SubaccountNumber, PlanID, FeatureID From #TempList  ENDGOHere is the method I used to call the first sp: (also with irrelevant stuff removed)public void saveCurrentMobile()           {
                      calculateTotals();
                      InvoiceDataSet dataset = InvoiceDataSet.GetInstance();
                      SqlConnection conn = (SqlConnection)Session["connection"];
                      SqlCommand cmdUpdateMobile;
                      cmdUpdateMobile = new SqlCommand("usp_updatemobile", conn);                      cmdUpdateMobile.CommandType = CommandType.StoredProcedure;
                      SqlParameter invoicedate = cmdUpdateMobile.Parameters.Add("@InvoiceDate", SqlDbType.SmallDateTime);                      invoicedate.Value = DateTime.Parse(Request.Params["InvoiceDate"].ToString());
                      SqlParameter cellnumber = cmdUpdateMobile.Parameters.Add("@SubaccountNumber", SqlDbType.VarChar, 50);                      cellnumber.Value = txtCellNumber.Text.Trim();
                      SqlParameter plan = cmdUpdateMobile.Parameters.Add("@PlanId", SqlDbType.Int);                      plan.Value = planid;
                      SqlParameter featurelist = cmdUpdateMobile.Parameters.Add("@FeatureList", SqlDbType.VarChar, 500);                      featurelist.Value = planform.FeatureList;
                    
                 //Response.Write(isthirdparty.ToString());                 Response.Write(thirdpartycompany);
                      SqlParameter cycle = cmdUpdateMobile.Parameters.Add("@Cycle", SqlDbType.Int);                      cycle.Value = Convert.ToInt32(Request.Params["Cycle"]);
                      int returnvalue = runStoredProcedure(cmdUpdateMobile); //the sp is called within this method.
 
                      if (returnvalue != 0)                      {                          dataset.fillMobileTable();                         Response.Write("Mobile Subaccount Saved!");                      }           }

Is There Any Way To Bacground A Long Running Stored Procedure?

Feb 21, 2000

I have a stored procedure being called from Visual Cafe 4.0 that takes over 30 minutes to run. Is there any way to backround this so that control returns to the browser that the JFC Applet is running in? The result set is saved to local disk and an email message sent to the user on completion.
Thanks, Dave.

Problems Running A Good Stored Procedure As A Job

Dec 13, 1999

I wrote a Stored Procedure I wish to run as a job. It inserts data to a linked server. The stored procedure runs fine from the sql query analyzer but fails as a job. There are no permissions assigned to this stored procedure as I beleive it runs under the context of sa which has default access granted.

Can someone give me some insite why this stored procedure won't run as a scheduled job?

ALTER PROCEDURE tsul_insertintolinkedserver
AS
DECLARE @srvname varChar(20)
SELECT @srvname = @@servername
insert into THOMAS.tsnet.dbo.usagelog
select id, tsgroup, account, error, failedpin, type, servername, ipbrowser, cid, logintime, expand , msgspresent, msgslistened, @srvname
from usagelog
where id >
( select max(id) from THOMAS.tsnet.dbo.usagelog
where hostserver = @srvname
)

Thanks in advance-

Running A Stored Procedure Using Output Result.

May 12, 2008

Hey guys!

I've come a huge ways with your help and things are getting more and more complicated, but i'm able to figure out a lot of things on my own now thanks to you guys! But now I'm REALLY stuck.

I've created a hierarchal listbox form that drills down From

Product - Colour - Year.

based on the selection from the previous listbox. i want to be able to populate a Grid displaying availability of the selected product based on the selections from the listboxes.

So i've written a stored procedure that selects the final product Id as an INPUT/OUTPUT based on the parameters PRODUCT ID - COLOUR ID - and YEAR ID. This outputs a PRODUCT NUMBER.

I want that product number to be used to populate the grid view. Is there away for me to do this?

Thanks in advanced everybody!

Question Regarding Running A Stored Procedure As A Job Step

Apr 16, 2007

I am running a stored procedure as a job step and in the stored procedure I use return to pass one of several possible values when there is an error in processing (not an system error) so that the job step will fail. However, even when I return a non-zero value using return the job step completes as successful. What should I be doing so that the job step picks up the non-zero value and then indicates the step failed?

Long Running Stored Procedure Status

Mar 24, 2008

I have a stored procedure in SQL 2005 that purges data, and may take a few minutes to run. I'd like to report back to the client with status messages as the sp executes, using PRINT statements or something similar. I imagine something similar to BACKUP DATABASE, where it reports on percentage complete as the backup is executing.

I can't seem to find any information on how to do this. All posts on this subject state that it's not possible; that PRINT data is returned after the procedure executes. However it would seem possible since BACKUP DATABASE, for example, does this.


Is there any way to send status type messages to the client as the sp is executing??

Thanks.
