Concurrency Issue In Result Returned From Stored P
Dec 11, 2007
I am working on application developed in ASP.NET 2.0 that uses lots of stored procedures from the SQL Server 2000 backend database.When the app is under load you occasionally see incorrect data returned to the page after running stored procedures.
All the stored procedures have been tested and appear to be fine. it's as if under load the returned data from the stored procedures is getting 'mixed' with another concurrent session.
Please let me know what could be the reason behind it
I have a SQL Server stored procedure that performs several queries and therefore returns several "result sets" at any one time.
Wiring it up via ADO.NET I populate a DataSet with a number of items in the Tables collection - which is great - and I can give each item a name for identification purposes once the DataSet is populated.
But I'd like to know if there is some way I can set the names of each result set *within the text of the stored procedure*, i.e. before the DataSet gets populated.
I have a novice question. How does one suppress result sets returned from a stored procedure?
I have created a procedure which makes use of multiple stored procedures . The purpose of this procedure (lets call it procA), is to count the rows returned from other procedures. The €œOther€? procedures will return rows having an unknown number of columns. I would like to limit any changes which may be needed to be made to the €œOther€? procs.
Once procA has collected all of the information (@@rowcount) from the inner procedures, then it will return a result set having several columns €“ mainly the subProcedure name and number of rows returned.
The purpose of procA is to query several subsystems and identify which ones need attention.
Cursor While Loop exec @ProcName @ObjectName,@userID,@syncDate set @recs = @@rowcount;
We have multiple employees assigned to the same assignment sometimes, and my query is skewed as that if there are 2 people assigned to the ssame assigment I can only see the amt of time worked for the 1st person. Â What should I do to remedy this?
Ouput I am receiving is
BadgeNum - Assignment -- FullName --TimeworkToday A2323 Â ---- Accident Reconstruction ---- Football Helmet ---- .50 AB12 ---- Accident Reconstruction ---- Brown Shoe ---- Null AB66 ----- Accident Reconstruction ---- Black Shoe ---- Null ABB28 ---- Accident Reconstruction ---- White Shoe ---- Null
--And now here it's a new assignment so timeworktoday is populating
Hi,I got another question here:I want to use query like this:SELECT * FROM (sp_lock AS T) WHERE objectID = ...The purpose is that I want to query the result set returned by sp_lockusing derived table, but it doesn't work. Why?Thanks,Baihao--Posted via Mailgate.ORG Server - http://www.Mailgate.ORG
Is it possible to get the result from an EXEC(@sqlcommand) statement into a variable?
As part of a SQL loop, it is necessary for me to run an EXEC() command to process an SQL statement. I have succesfully implemented this, but have been unable to get the results from the EXEC() statement into a variable to allow this data to be inserted into a table. Is this possible?
For Example (I know this doesn't work, but it is effectively what I am trying to achieve):
select @result = EXEC(@sqlcommand)
I could then use the @result variable in an insert statement to update a table with the results from the EXEC command.
In MySQL we use "SELECT (....) LIMIT 0, 10" to only return the first 0 to 10 records. Alternatively we could do "LIMIT 10, 20" to return the 10th to 20th records.
Gurus.I do not know if it is possible, but here is what I want to do.I want to allow user to page the SQL result, so he could decides toreturn from row 10 to row 20, or row 100 to 200, without returns thewhole resultset. Every time he sends another request, I do not mind tohit the database again, (I do not want to cache the result in themiddle tier server, scalability issue), and I know that I could achievethis with CURSOR, but unfortunately the FOR XML is not allowed in aCURSOR statement .(I know that I could achieve what I want to do by writing custom codein the middle tier, but I just want to see if there is a way to do thison the database side.)Any comments & suggestion is greatly appreciated.Thanks in advance.(I am using SQL2005)John
I am trying to set up an Execute SQL Task that will feed into a foreach loop for processing of data. I am using an ADO.NET Connection with Direct input with full result set. I have tried using "select * from <table>" and also "select <column1>, <column2> from <table>". I have user variables set in the package and have the table cfolumn names listed in result name and the appropriate package variable in variable name on the Result Set tab. There is a total of 53 columns per row and the number of rows that should be returned can be anywhere from none to several hundred. Upon trying to run the package, I am receiving Error: 0xC00291E2 at Execute SQL Task, Execute SQL Task: There is an invalid number of result bindings returned for the ResultSetType: "ResultSetType_Rowset".
I have a requirement that requires detection of rows deleted/updated byother processes. My business objects call stored procedures to create,read, update, delete data in a SQL Server 2000 data store. I've donea fair amount of research on concurrency handling in newsgroups andother resources. Below is what I've come up as a standard forhandling concurrency thru stored procedures. I am sharing with everyoneso I can get some comments (pro/con) regarding this approach and see ifanyone can find any holes for this solution.Below is the DDL, DML and a Stored Proc demonstrating the approach. Iam using a rowversion column for concurrency checking. Another approachthat is less intrusive (doesn't require having a rowversion column inall tables) is using checksum. I may eventually use checksum but theprocess flow should be almost identical. Looking forward to anyone'scomments.Thx, BZ--xxxxxxxxxxxxxxxxxxxxxxxxxxx--IF EXISTS (SELECT * FROM sysobjects WHERE type = 'U' AND name ='ApplicationUsers')BEGINPRINT 'Dropping Table ApplicationUsers'DROP Table dbo.ApplicationUsersENDGOPRINT 'Creating Table ApplicationUsers'GOCREATE TABLE dbo.ApplicationUsers(LoginName varchar (20) NOT NULL Primary Key,LoginPassword varchar (50) NOT NULL,LoginAttempts int NOT NULL default(0),EmailAddress varchar(25) NOT NULL Unique,DataVersion rowversion NOT NULL)GOIF EXISTS (SELECT * FROM sysobjects WHERE type = 'P' AND name ='UpdateUser')BEGINPRINT 'Dropping Procedure UpdateUser'DROP Procedure dbo.UpdateUserENDGOPRINT 'Creating Procedure UpdateUser'GOCreate Procedure dbo.UpdateUser@loginName Varchar (20),@loginPassword Varchar (50),@loginAttempts Int,@emailAddress Varchar(25),@dataVersion Rowversion OutputAs/************************************************** ****************************** Name: dbo.UpdateUser** Desc: Updates an Application User instance**** Parameters:** Input** @loginName** @loginPassword** @loginAttempts** @emailAddress** @dataVersion. row version used for concurrency control.**** Output** @dataVersion. updated row version used for concurrencycontrol.**** Return** 0 for Success.

I'm using Java to connect to a SQL Server 2000 database. I connect using the Driver Manager with Sun's odbc driver ( sun.jdbc.odbc.JdbcOdbcDriver ) or I can use the jdbc driver provided by Microsoft (com.microsoft.jdbc.sqlserver.SQLServerDriver)
The Java application makes 1 Connection.
Within the database there exists a stored procedure that updates 2 Tables. The tables have a fixed number of rows that get updated continuously by calls to this stored procedure.
The Java application has a thread pool of 15 threads that create 15 CallableStatements (1 per thread) using the same instance of the Connection object.
According the the Microsoft JDBC driver docs, 1 Connection with multiple calls to the Callable statements is how it's supposed to be done. The following is an excerpt from Microsoft's "SQL Server 2000 Driver for JDBC User’s Guide and Reference" (page 86) regarding Connection Managment: Managing Connections
Connection management is important to application performance. Optimize your application by connecting once and using multiple statement objects, instead of performing multiple connections. Avoid connecting to a data source after establishing an initial connection. This is precisely what I'm doing, but I do not know if the the stored procedures are being run concurrently, the documentation does not tell me.
So my question: What is happening inside SQL Server 2000?
I've implemented an SQL-CLR stored procedure which makes an HTTP connection using the WebClient class to a server where the processing on the web server takes 10 seconds.
If I fire off a bunch of requests to the stored procedure, e.g. 80 in 1 second I noticed that SQL Server 2005 (Express Edition) only allows 2 concurrent network connections at a time.
I can confirm this by looking at the timing of the results when they come back, basically I get 2 results every 10 seconds and by doing a 'netstat -a' on the web server I notice that there are never more than 2 HTTP connections from the SQL Server at a time.
Is this some sort of sheduling policy in terms of the number of concurrent external network accesses allowed by CLR objects running in SQL Server? Or some side effect of the way the WebClient class blocks in terms of waiting for a network response?
I was expecting all 80 of the requests to block waiting on a network response almost immediately and then for all 80 of them to pretty much complete and return 10-11 seconds later.

Hi, I use a strong-typed DataSet to build the data access tier of my application, and the IDE generates most of code for me. However I can't find a way to get the value returned by a stored procedure(The stored procedure seems like 'RETURN 0').I noticed that a @RETURN_VALUE parameter is added automatically for each query method, but I don't know how to read the value. Anybody could help me with the problem? Thanks.
I've got a query on a particular table returning an odd result:
SELECT DISTINCT WorkStation FROM Invoice WHERE WorkStation Is Not Null ORDER BY WorkStation
This query returns the rows I'd expect plus a null row. This doesn't happen in databases at other sites, or in other tables at this site. The following query behaves as I'd expect returning only non-null AccountNumbers.
SELECT DISTINCT AccountNumber FROM Suppliers WHERE AccountNumber Is Not Null ORDER BY AccountNumber
I can't reproduce these results on another site on a table of the same structure, or on another table at this site.
Any suggestions as to what might be going on?

I have an asp.net 1.1 website that uses sql server 2000 and vb.I have a bit of a dilema, when I run a stored procedure in a webpage it returns the wrong value, but if I run itin the query analyzer the correct value is returned. Dim orderHistory As nlb.OrdersDB = New nlb.OrdersDB
' Obtain Order ID from QueryString Dim OrderID As Integer = CInt(Request.Params("ID"))
' Get the customer ID too Dim myNewCustomerId As Integer = 0 myNewCustomerId = orderHistory.GetOrderCustomer(OrderID)
Public Function GetOrderCustomer(ByVal orderID As Integer) As Integer
' Create Instance of Connection and Command Object Dim myConnection As SqlConnection = New SqlConnection(ConfigurationSettings.AppSettings("ConnectionString")) Dim myCommand As SqlCommand = New SqlCommand("nlbsp_OrdersCustomerID", myConnection)
' Mark the Command as a SPROC myCommand.CommandType = CommandType.StoredProcedure
' Add Parameters to SPROC Dim parameterOrderID As New SqlParameter("@order_id", SqlDbType.Int, 4) parameterOrderID.Value = orderID myCommand.Parameters.Add(parameterOrderID)
Dim parameterOrderCustID As New SqlParameter("@customer_id", SqlDbType.Int, 4) parameterOrderCustID.Value = ParameterDirection.Output myCommand.Parameters.Add(parameterOrderCustID)
'Open the connection and execute the Command myConnection.Open() myCommand.ExecuteNonQuery() myConnection.Close()
' Return the customer_id (obtained as out paramter of SPROC)
If parameterOrderCustID.Value <> 0 Then Return CInt(parameterOrderCustID.Value) Else Return 0 End If
End Function
the stored procdure is CREATE PROCEDURE [dbo].[nlbsp_OrdersCustomerID] ( @order_id int, @customer_id int OUTPUT ) AS
/* Return the customer_id from the Orders. */ SELECT @customer_id = customer_id
FROM nlb_Orders
WHERE order_id = @order_id GO
I know a particular order_id returns a value of 1. But when I run it in the webpage it always comes back as 2. Any ideas would be appreciated ThanksPete
The following query only brings back too much data in the table - there are duplicates and the lab it shows is wrong. The problem is: AND a.calLab = f.ID in the Where statement. Some equipment does not need calibration, so, a.calDueDate = 0 AND a.calLab would be NULL or 0. tblLabs ID field has 1 - 18 (Labs) - no 0 and of course no null I need to get the rest of the data. Any suggestions? Thanks..... Zath

I can run it in Query Analyzer and it returns one record as it should. I want it in ASP.NET to return the amount of rows that are effected, e.g that the login is correct.

I have the following stored procedure. The good thing is I finally got the syntax to the point where it doesn't blow up, but I was under the impression the "print" statement would print my result.

I am using the following stored procedure to insert a value into the database. I am new to stored procedures so I need help. Basically this stored procedurewill only insert a value for "CustomerName" if it is not a duplicate value. So I noticed in My C# when I call this stored procedure, a negative one "-1"is returned if the insert is not performed because of a duplicate value. Is that correct? Should I be getting back a negative one "-1" ? You seeI thought that a Zero "0" would be returned if the insert was not performed.Not a negative one?

Hi, Can we validate the returned order of fields from a stored procedure? Infact, i am taking a query as user input and extracts the results based on the query but for that order of fields specified in a query is important. Can i check the order after the query is run i.e if this is entered "select field1,field2,field3 from table" then i need to check the order of the resultset generated. I can't check the query before the resultset is generated because a user can enter bunch of queries. Any way will work, tsql or .net app. Thanks,

I have a strange problem. I have some code that executes a sql query. If I run the query in SQL server query analyzer, I get a set of data returned for me as expected. This is the query listed on lines 3 and 4. I just manually type it into query analyzer. Yet when I run the same query in my code, the result set is slightly different because it is missing some data. I am confused as to what is going on here. Basically to examine the sql result set returned, I write it out to an XML file. (See line 16). Why the data returned is different, I have no idea. Also writing it out to an XML file is the only way I can look at the data. Otherwise looking at it in the debugger is impossible, with the hundreds of tree nodes returned. If someone is able to help me figure this out, I would appreciate it. 1. public DataSet GetMarketList(string region, string marketRegion)2. {3. string sql = @"SELECT a.RealEstMarket FROM MarketMap a, RegionMap b " + 4."WHERE a.RegionCode = b.RegionCode"; 5.
