SQL Server 2000 And Stored Procedure Concurrency
Apr 1, 2005
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?

Hi
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.
[Microsoft.SqlServer.Server.SqlProcedure]
public static int CreditAuthorisation(string Name, decimal Amount)
{
WebClient client = new WebClient();
string result = client.DownloadString("http://someserver/Test.aspx");
return int.Parse(result);
}
Cheers

I have a stored procedure that builds a sql statement and executes it. When run in Query Analyzer it runs successfully and displays records as it should. When I open a recordset with the stored procedure from VBA it executes the codes but doesn't open the recordset.
The store procedure is:
ALTER PROCEDURE dbo.spTest
AS
DECLARE @sColumns varchar(2000)
DECLARE @sFrom varchar(2000)
DECLARE @sWhere varchar(2000)
DECLARE @sSqlString AS nvarchar(2000)
SET @sColumns = 'dbo.tblDoctor.lastname '
SET @sFrom = 'FROM dbo.tbldoctor '
SET @sWhere = 'WHERE dbo.tbldoctor.doctorcode is not null '
SET @sSqlString = 'SELECT ' + @scolumns + ' ' + @sFrom + ' ' + @swhere PRINT '@scolumns ' + @scolumns
PRINT '@sfrom ' + @sfrom PRINT '@swhere ' + @swhere PRINT 'sqlstring ' + @sSqlstring
EXEC Sp_executesql @sSqlString
The VBA code is:
Private Sub Command0_Click()
Dim cn As Connection
Dim rs As New ADODB.Recordset
Dim strsql As String
Set cn = CurrentProject.Connection
strsql = "exec spTest"
With rs
.Source = strsql
.ActiveConnection = cn
.CursorType = adOpenKeyset
.LockType = adLockReadOnly
.Open
End With
Debug.Print rs.RecordCount & " records found"
End Sub
When it hits the line with rs.recordcount it displays the following error: "Operation is not allowed when object is closed" referring to the rs recordset never being opened.
Any suggestions?

Hi everyone,
I am new to the forum and I have a problem with a stored procedure in SQL Server 2000. I use a stored procedure that returns a string but the problem is that my variable is empty at least I think it's empty.
With the code below the variable is not empty:
set @Ssql = 'select Cust_Company_id, fix_price from GEC_FixPrice where priority > 0 and cust_company_id like ' + char(39) + @InvoiceLine_CustCompanyid + char(39) + ''
But when I use the code below it's empty
- set @sSql = 'select Cust_Company_id, fix_price from GEC_FixPrice where priority > 0 '
- set @sSql = @sSql + ' and cust_company_id like ' + char(39) + @InvoiceLine_CustCompanyid + char(39) + ''
I also tried this :
- set @Start = 'select Cust_Company_id, fix_price from GEC_FixPrice where priority > 0 '
- set @End = ' and cust_company_id like ' + char(39) + @InvoiceLine_CustCompanyid + char(39) + ''
- set @sSql = @Start + @End
This works also, so I don't get why the second example won't work and the second example is the one I want to use.
So does anyone has a clue :confused:
thx in advance,
grtz

Hi All,I have a table that holds pregenerated member IDs.This table is used to assign an available member id to web sitevisitors who choose to register with the siteSo, conceptually the process has been, from the site (in ASP), to:- select the top record from the members table where the assigned flag= 0- update the row with details about the new member and change theassigned flag to 1- return the selected member id to the web pageNow I'm dealing with the idea that there may be brief, high trafficperiods of registration, so I'm trying to build a method (storedprocedure?) that will ensure the same member id isn't returned by theselect statement if more than 1 request to register happens at thesame instant.So, my question is, is there a way, once a record has been selected,to exclude that record from other select requests, within the boundsof a stored procedure?ie:- select statement is executed and row is instantly locked; any otherselect statement running at that exact moment will receive a differentrow returned and sill similarly lock it, ad nauseum for as manysimultaneous select statements as take place- row is updated with details and flag is updated to indicate themember id is no longer unassigned- row is released for general purposes etcIf what I'm suggesting above isn't practical, can anyone help meidentify a different way of achieving the same result?Any help immensely, immensely appreciated!Much warmth,Murray

Hi Everybody,
I am trying to update a column Percentage in a table named Critical Doctors with a column named
PercentTime from tblPercent table, Where the column Doctor matches with any DoctorId from
tblPercent.
I am getting an error message for the following query.
Have Two tables
1.CriticalDoctors
2.tblPercent
update CriticalDoctors set Percentage =
(select PercentTime from tblPercent)
where CriticalDoctors.Doctor = (select DoctorId from tblPercent)
Server: Msg 512, Level 16, State 1, Line 1
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <=
, >, >= or when the subquery is used as an expression.
The statement has been terminated.
Pls give me reply on how to write a stored procedure so that I can equate the percentage column
with one value and also check the condition with one value.
Thanking you guys in advance.

Hi, I have a problem with "database output" window in executing a select-sp in vs 2005 standard. The db is a sql server 2000 one.When I execute the sp within VS, the database output correctly displays the execution information:No rows affected.(1 row(s) returned)@RETURN_VALUE = 3 but I can't see the returned rows (3 rows are returned); I only see the column names and no data.Running [dbo].[spBkm_GetList] ( @IDUser = <DEFAULT>, [.........]).IDBkm UIBkm IDUser --------------------- -------------------------------------- ---------
No rows affected. If I run the same sp in Sql Server Manager Studio Express it correctly shows the data of the 3 rows returned. The sp uses EXEC sp_executesql @Sql, @ParamList, ...... for executing the sql statement and the last line of sp is RETURN @@ROWCOUNTI've tried removing the "RETURN @@ROWCOUNT" with no success. The problem affects only one sp, the others, which are absolutely similar, work properly . I don't know what is the problem...Any idea?Thanks in advance

Hi there,
I was wondering if someone can point out the error or the thing I shouldn't be doing in a stored procedure on SQL Server 2005. I want to switch from SQL Server 2000 to SQL Server 2005 which all seems to work just fine, but one stored procedure is causing me headache.
I could pin the problem down to this query:
DECLARE @Package_ID bigint
DECLARE @Email varchar(80)
DECLARE @Customer_ID bigint
DECLARE @Payment_Type tinyint
DECLARE @Payment_Status tinyint
DECLARE @Booking_Type tinyint
SELECT @Package_ID = NULL
SELECT @Email = NULL
SELECT @Customer_ID = NULL
SELECT @Payment_Type = NULL
SELECT @Payment_Status = NULL
SELECT @Booking_Type = NULL
CREATE TABLE #TempTable(
PACKAGE_ID bigint,
PRIMARY KEY (PACKAGE_ID))
INSERT INTO
#TempTable
SELECT
PACKAGE.PACKAGE_ID
FROM
PACKAGE (nolock) LEFT JOIN BOOKING ON PACKAGE.PACKAGE_ID = BOOKING.PACKAGE_ID
LEFT JOIN CUSTOMER (nolock) ON PACKAGE.CUSTOMER_ID = CUSTOMER.CUSTOMER_ID
LEFT JOIN ADDRESS_LINK (nolock) ON ADDRESS_LINK.SOURCE_TYPE = 1 AND ADDRESS_LINK.SOURCE_ID = CUSTOMER.CUSTOMER_ID
LEFT JOIN ADDRESS (nolock) ON ADDRESS_LINK.ADDRESS_ID = ADDRESS.ADDRESS_ID
WHERE
PACKAGE.PACKAGE_ID = ISNULL(@Package_ID,PACKAGE.PACKAGE_ID)
AND PACKAGE.CUSTOMER_ID = ISNULL(@Customer_ID,PACKAGE.CUSTOMER_ID)
AND PACKAGE.PAYMENT_TYPE = ISNULL(@Payment_Type,PACKAGE.PAYMENT_TYPE)
AND PACKAGE.PAYMENT_STATUS = ISNULL(@Payment_Status,PACKAGE.PAYMENT_STATUS)
AND BOOKING.BOOKING_TYPE = ISNULL(@Booking_Type,BOOKING.BOOKING_TYPE)
-- If this line below is included the request will take about 90 seconds whereas it takes 1 second if it is outcommented
--AND ADDRESS.EMAIl LIKE '%' + ISNULL(@Email, ADDRESS.EMAIL) + '%'
GROUP BY
PACKAGE.PACKAGE_ID
DROP TABLE #TempTable
The request is performing quite well on the SQL Server 2000 but on the SQL Server 2005 it takes much longer. I already installed the SP2 x64, I'm running the SQL Server 2005 on a x64 environment.
As I stated in the comment in the query it takes 90 seconds to finish with the line included, but if I exclude the line it takes 1 second.
I think there must be something wrong with the join's or something else which has maybe changed in SQL Server 2005. All the tables joined have a primary key.
Maybe you folks can spot the error / mistake / wrong type of doing things easily.
I would appreciate any help you can offer me to solve this problem.
On the web I saw that there is a Cumulative Update 4 for the SP2 which fixes the following:
942659 (http://support.microsoft.com/kb/942659/)
FIX: The query performance is slower when you run the query in SQL Server 2005 than when you run the query in SQL Server 2000
Anyhow I think the problem is something else, I haven't tried out the cumulative update yet, as I think it is something different, more general why this query takes ages to process.
Thanks again for any help
Best regards,
Pascal

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.

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 some code that I need to run every quarter. I have many that are similar to this one so I wanted to input two parameters rather than searching and replacing the values. I have another stored procedure that's executed from this one that I will also parameter-ize. The problem I'm having is in embedding a parameter in the name of the called procedure (exec statement at the end of the code). I tried it as I'm showing and it errored. I tried googling but I couldn't find anything related to this. Maybe I just don't have the right keywords. what is the syntax?
CREATE PROCEDURE [dbo].[runDMQ3_2014LDLComplete]
@QQ_YYYY char(7),
@YYYYQQ char(8)
AS
begin
SET NOCOUNT ON;
select [provider group],provider, NPI, [01-Total Patients with DM], [02-Total DM Patients with LDL],
[Code] ....

I need to automate the following function. I know I can do this in .NET but I need to have a DTS package setup so it executes every evening.
I have a view that produces a list of sales errors. I want to grab the SaleID from each record and insert a record into a "Current Queue" table.
Here is another example of what I'm trying to do...
SELECT SaleID FROM vw_SalesErrors
- with the results of the SQL statement above
INSERT INTO tbl_QueueRecords
(SaleID, QueueID)
VALUES
(@SaleID, 14)
I'm assuming there is a way to automate this into a single stored procedure or at least a DTS pacakge.
Thanks for all of your help.

Hi,Sorry, this is a very easy question. I have to create a storedprocedure in a SQL SERVER Database.I have read lots on MSDN about the syntax of this stored procedure :ie.CREATE PROCEDURE spGetContctDetailsAS-- get everything out of contact tableSELECT * FROM tblContactbut I cannot find anywhere how to actually add this procedure, so thatit is accessable in my VB.NET program.What I am asking is : what screen do I type this into? Is it QueryAnalyzer, if so where?Its got me oh so confused. When I've got time i'll read all about SQLServer, but for this morning I need to know how to simply add thatStored Procedure to my database.Thanks LOADS for any help.

Hi there everybody,
I am writing a sales managing software using C# in .NET 2005.
The program was used to work properly with sql server 2000.
I decided to write a "FILE Version" of sofware using sql server express 2005 , and detached db from 2000 , attaching it to 2005 using AttachDBFileName clause in connection string.
But the problem is when program executes something like this:
EXEC [AddOrder] ...
two rows inserted instead of one.and when I use server explorer of VS2005 to launch SP, it works fine.
I should mention again that same code works correctly when I change connection string and force it to use sqlserver 2000.
Any ideas?
Kind Regards: Ali

I have this stored procedure that takes a few parameters like date andmerchant ID, and basically goes through a set of if-then statements to builda SQL SELECT string.When we upgraded from SQL Server 7.0 to 2000, the stored procedure stillworked from Query Analyzer, but not in BCP. It used to work in BCP justfine with 7.0. The error I get now is:SQLState = S1000, NativeError = 0Error = [Microsoft][ODBC SQL Server Driver]BCP host-files must containat least one columnWhat's really strange is, if I instruct the stored procedure to simply printthe SELECT string, then cut-and-paste it into the end of stored procedurecode (assigning it to the variable that already contains the SELECT string),then it works from BCP.Any help would be greatly appreciated.Aston
