Simultaneous DB Access
Mar 12, 2006
I have C# Express and the SQL Express Management Studio CTP installed. So far, I've been forced to disconnect from the server in one app to connect to it in the other. I understand there is something around a 4 connection limit in SQLServer Express, so I don't see the problem.
During one of these episodes, SQL Mgmt Studio hung while opening DB properties, then the SQLServer service couldn't be stopped. Now the DB can't be opened even after a reboot.
Help?

Hi Everyone,
I have a software solution that consists of two separate applications that share a SQL Server Express database on a single computer. Everything is working great, except when both of the applications want to access the database at the same time. All I can find is information on configuring multi-user access in a distributed system. I'd appreciate any information on configuring multi-application access on a single computer.
Thanks,
Mike

If multiple snapshots for the same report attempt to generate at the same second, is there something in place to prevent them from conflicting with each other?
Our SSRS 2005 application will use a console app that we are writing to change the default parameters on each report and call the CreateReportHistorySnapshot method. This application will be multi-threaded, so there is a possibility that multiple versions of the same report with different parameters will attempt to run at the same time. We need to be sure that these snapshots will not conflict and return the appropriate SnapshotHistoryID for that report run.
From looking at the History table in the ReportServer database it looks like there are uniqueIDs and other keys that would prevent duplicates, but what if the requests come in at the same time? Is SSRS 2005 smart enough to delay for a second so that there is not a duplicate? Since the way you reference these snapshots in your URL is with the Snapshot Time in UTC format, that only goes out to full seconds (2006-05-02T00:00:00).
Sorry for the length, but I could not think of how to condense this.
Thanks,
Steve

Hi,
I have an application resource that is accessible from multiple clients applications that all have access to a common SQL Server db. By this, I mean, multiple clients can potentially connect to this resource at any given time. I want to limit the usage of this resource to one client at a time and was thinking about simply using SQL to maintain the name of the client that currently has "control" of the resource.
My question pertains to the case where two clients are executing a SQL query, simultaneously, to check whether someone has control of the resource or not. If two users were to simultaneously execute this query, do i have to lock the table in order to ensure that both users are not viewing data in an incorrect state? Or, does SQL Server ultimately execute the queries in a specific order? Meaning, the requests are simultaneous from a human standpoint but one request may have actually come in a millisecond before the other one and SQL server executes that query first, and then the second query. Is this how it works?
Thanks,
Paul

Hi All,
I have a Windows 2003 Server. Planning to use SQL Server to act as the main Database Server which needs to cater to over 100's of simultaneous connections.
Can anyone share with me the default maximum simultaneous connections and the maximum allowed simultaneous connections for the following versions:
- MSDE
- 2000
- 2005 Express
- 2005
Hope I can get more professional advice from you guys.
Thanks.

Using the Import/Export Wizard, it is easy to set up SSIS jobs to import multiple tables in one task. However, SSIS appears to grab a connection to the source database and the destination database for each table indicated in the task sometime prior to doing the actual data transfer. Even though the transfer seems to be done a few tables at a time, all the connections are held throughout the execution of the task.
This has two effects:
1. The task may fail if the number of connections exceeds the limit of user connections set for the database
2. There is a severe impact on the other users of the databases (in my case, the source is a production system)
Is there any way to control the number of simultaneous connections that SSIS data transfer packages initiate?
I can, of course, define the package to have a small number of tables (thus limiting the connections), but in real life I need to transfer almost 700 tables, so limiting the number of tables per task to 20 or 25 produces an awkwardly large, and error prone, number of tasks. And since this definition must be done for multiple (not quite identical) databases, the extra effort of defining small collections of tables is signifcant.

Greetings!
Are there any limit of simultaneous users and/or connections when running SQL Express? The free license of SQL Express, does that include use by any number of users/devices?

Hi, can anyone help me? I want to know whether is it possible to insert records simultaneously in both master & detail tables?
For elaboration, say there is a master table contains (orderid,orderdate,amount) and details table contains (orderid, productid,qty,price). 1 record of master table associated with n records of details table. Can it be possible to insert both the 1 record at master table with n records in details table in a single sql statement?

Is there a way to get the Report Manager to allow a single user to
execute more than 1 report at a time? Currently, each user can only
have a single report being executed at a time. It looks like any
other reports are being queued and executed serially.

How can I prevent a package, or a section of a package, from being run more than once simultaneously? The package makes use of a staging database table, and if two copies of this package are run at the same time, there will be a race condition and possible corruption of the data in the database table. I have also noticed that the SSIS logging gets messed up and starts overwriting itself if I have more than one of these packages run at the same time.
What I am thinking of should work the same way as a serializable transaction lock on a normal query, where one query has to wait if another query has a lock on the table. I don't want the package to throw an error, I want it to wait until the other one is done.
I have been trying to use transactions in a test SSIS package, but they are not quite doing what I want them to do. I put various SSIS steps in a sequence container and require a serializable transaction. I have also tried putting the transaction at the package level, but that is not preventing simultaneous package runs.
Is there a built-in way to do this that is easy to implement? Otherwise, what I could do is insert a flag into the database indicating that a package is running, then make sure to reset the flag on any error or on completion. It seems like this alternate method could be error-prone though.
I am using SP2.

I am trying to insert into two tables simultaneously from a formview. I read a few posts regarding this, and that is how I've gotten this far. But VWD 2005 won't let me save the following stored procedure. The error I get says “Incorrect syntax near ‘@WIP’. Must declare the scalar variable “@ECReason� and “@WIP�.� I'm probably doing something stupid, but hopefully someone else will be able to save me the days of frustration in finding it. Thanks, the tables and procedures are below.
I made up the two tables just for testing, they are:
tbltest
ECID – int (PK)

Hi,
could somebody please let me know what is the maximum number of simultaneous users/connection per single SQL Server 7.0 box? Licenses are not the issue here, rather the number of physical connections supported before another server needs to be purchased.
Another variation of this question would be what's the highest number of databases that 7can be created on SQL 7.0 server and what is the highest number of physical connections supported per database? Again, licenses are not the issue. Thanks a lot in advance.

I was going over this article , and was intrigued by this statement "If SQL Server 2005 Express is running on Windows XP Home, it is limited to five simultaneous connections. If it is running on Windows 2000 or Windows XP Professional, it is limited to 10 simultaneous connections. However, these are limitations of the operating system and not of SQL Server 2005 Express."
What are simultaneous connections? Is this related to Max worker threads defined as 255 on other editions? How does underlying OS impose how many connections can be done to SQL server. And finally how many simultaneous connections can be done in Windows Server 2003?

Hello
I am trying to call the same package with different starting parameters using asynchronous method calls.
My code is
namespace ReconHost
{
public partial class HostContainer : Form
{
public delegate void InvokePackageHandler(
Microsoft.SqlServer.Dts.Runtime.Application app,
int var
);
Microsoft.SqlServer.Dts.Runtime.Application app;
public HostContainer()
{
InitializeComponent();
for (int i = 0; i < 2; i++)
{
app = new Microsoft.SqlServer.Dts.Runtime.Application();
InvokePackageHandler asyncInvokePackageHandler = InvokePackage;
asyncInvokePackageHandler.BeginInvoke(app, i, null, null);
}
}
public void InvokePackage(Microsoft.SqlServer.Dts.Runtime.Application app, int var)
{
Package pkg = app.LoadPackage(@"c:GRSGRSGRSTest_Async.dtsx", null);
pkg.Variables["intVar"].Value = var;
pkg.Execute();
pkg = null;
}
}
}
If I set the for loop to loop just once, the package is executed fine. Any more than once and only one instance of the package is executed.
Does anyone know what I am doing wrong? I know it is possible to execute the two package instances simultaneously because you can use DTexecUI.exe on two clients to do this.
Thanks in advance

Hello everyone, I am hoping someone can help me with this problem. Iwill say up front that I am not a SQL Server DBA, I am a developer. Ihave an application that sends about 25 simultaneous queries to a SQLServer 2000 Standard Edition SP4 running on Windows 2000 Server with2.5 GB of memory. About 11 of these queries are over views (all overthe same table) and these queries are all done from JDBC but I am notsure that matters. Anyway, initially I had no problem with thesequeries on the tables and the views with about 4 years of information(I don't know how many rows off hand). Then we changed the tables toreplicated tables from another server and that increased the amount ofdata to 15 years worth and also required a simple inner join on 2columns to another table for those views.Now here is the issue. After times of inactivity or other times duringthe day with enough time between my test query run I get what lookslike blocking behavior on the queries to the views (remember these allgo to the same tables). I run my 25 queries and the 11 view queriesall take about 120 seconds each to return (they all are withinmilliseconds of each other like they all sat there and then werereleased for processing at the same time). The rest of the queries arefine. Now if I turn around and immediately run the 25 queries again,they all come back in a few seconds which is the normal amount of time.Also, if I run a query on one of views first (just one) and then runthe 25 queries they all come back in a few seconds as well.This tells me that some caching must be involved since the times are sodifferent between identical queries but I would expect that one of thequeries would cache and thus take longer but the other 10 would befast, not all block for 2 minutes. What is more puzzling is that thisbehavior didn't occur before where now the only differences are:1) 3 times more data (but that shouldn't cause a difference from 3seconds to 120 and all tables have been through the index wizard with aSQL trace file to recommend indexes)2) There is now a join between 2 tables where there wasn't before3) The tables are replicated throughout the day.I would appreciate any insight into this problem as 120 seconds is waytoo long to wait. Thanks in Advance.Chris

Hi everyone. I hope that my question isn't too broad, but here it goes...
I am trying to figure out the best way to scale a SQL Server database so that it can handle a billion simultaneous users querying the same tables, and can easily scale to handle many billions of simultaneous users. The database must also have 999.99% availability. The number of licences and amount of hardware needed is not an issue.
Thanks in advance.

Hello, I have one store procedure that writes something data to one physical sql table 'MyTable' and on beginning I first call:DELETE FROM MyTableProcedure returns at the end data from 'MyTable' as on SELECT. PROBLEM:I started SQL Manager on my Laptop and on Computer near me and all pointed to same database (on Server) and I run that procedure simultaneously on Laptop and Computer at the same time (two hands on F5 button on these computers). Occasionally when clicking with both hands at the same time I got no records at the end of execution (on both computers), otherwise I got the results.WHAT I THINK IS PROBLEM:Somhow one SP start working and it did not come to the end and another computer called this SP and execute first command (DELETE FROM MyTable) and I got empty records at the end..WHAT I NEED:I need to prevent this situation to get empty records. All computers must get these records always. How I can use some sort of LOCKs to do this?Or to do that on C# application level using LOCK command? Thanks in advanceAleksandar

I have recently upgraded to SQL2014 on Win2012. The Access front end program works fine.
But, previously created Excel reports with built in MS Queries now fail with the above error for users with MS 2013. The queries still work for users still using MS 2007.Â
I also cannot create any new queries and get the same error message. If I log on as myself on the domain to another PC with 2007 installed it works fine, so I don't think it is anything to do with AD groups or permissions.

We need to insert data/rows from a SQL Server 2014 database into MS Access database. The problem is, there are so many columns (100+) in the table and there are so many insert transactions of this kind (from different tables) that it is not very easy to write the code in VB.NET that lists all column names.
Both the Access and SQL Server tables have the same number of columns and the equivalent data types, so inserting is not really the problem. It's just that is there a way to do an insert statement in T-SQL that does not name all the columns?

Hi guys,
I've been developing desktop client-server and web apps and have used Access and SQL Server Standard most of the time.
I'm looking into using SQL CE, and had a few questions that I can't seem to get a clear picture on:
- The documentation for CE says that it supports 256 simultaneous connections and offers the Isolation levels, Transactions, Locking, etc with a 4GB DB. But most people say that CE is strictly a single-user DB and should not be used as a DB Server.
Could CE be extended for use as a multi-user DB Server by creating a custom server such as a .NET Remoting Server hosted through a Windows Service (or any other custom host) on a machine whereby the CE DB would run in-process with this server on the machine which would then be accessed by multiple users from multiple machines??
Clients PCs -> Server PC hosting Remoting Service -> ADO.NET -> SQL CE
- and further more can we use Enterprise Services (Serviced Components) to connect to SQL CE and further extend this model to offer a pure high-quality DB Server?
Clients PCs -> Server PC hosting Remoting Service -> Enterprise Services -> ADO.NET -> SQL CE
Seems quite doable to me, but I may be wrong..please let me know either ways
Thanks,
CP

When running the following statement in SQL 2005, I get the error message "Access is denied":
exec master.dbo.xp_cmdshell 'TYPE \SERVER-BSHAREFILE.TXT'
The following are true about the network:
The SQL Server is installed on SERVER-A.
SERVER-A and SERVER-B are Windows 2003 servers on the same Windows 2003 domain.
The SQL Server and SQL Server Agent services are running under the domain account SQLSERVICE.
SQLSERVICE is a member of the Domain Admins group.
The Domain Admins group is part of the local Administrators group on SERVER-B.
The SQLSERVICE account has also explicitly been given Full Control to the folder referenced by \SERVER-BSHARE
xp_cmdshell use has been enabled on the SQL Server.
If I run the following command in SQL:
exec master.dbo.xp_cmdshell 'whoami'the following is returned: DOMAINSQLSERVICE
If I change the command to access the c: drive instead of a network drive, it executes successfully.
Can anyone shed some light on why I still cannot access any of the files in this folder using xp_cmdshell?

We have an application that requires write settings to reportserver virtual directory for the IUSR account when anonymous is turned on during the install. Once the install is complete, we lock down the IUSR account so that it only has browse access to the virtual directory when enabling anonymous access.
We automate the uninstall and install of our daily builds and I'm trying to figure out if I can automated this process somehow either through command line utility or in vbs.

Re: Possible Vista-only security issue opening a TCP connection to SQL2005
Please help. I have a problem that appears to be rare. I'm testing the culmination of a year's work and the error I'm getting is at the most basic level (the SQL connection) while everything else so far is working as coded.
My client is Windows Vista, apparently no firewall (I say apparently as in recent years MS have put more and more facades over the actuality of the operating systems), my server is Windows 2003 Server b3790 SP2 with SQL 2005 Standard 1399.06, again no firewall.
PortQuery 2.0 reckons that the server is listening on port 1433, too, so it doesn't seem like a firewall issue.
Nothing reported in either Event Viewers.
Here's the stack dump:

I have tried an old project which used to connect to the same server using a more basic connection string (it was a project which populated my Research db with fake data) and it also fails. When I ran this project successfully I'm pretty sure it was on an XP client.
I have also ran my TestHarness .exe on another client (WinXP) and it appears to pass this point and raises an exception that I believe is caused at a later point - so it looks like a Vista client issue.
Thanks in advance for your help,
Luke
P.S. Some losely related thoughts; the MSDN forum system still logs me out on Vista when I try to submit a thread, please sort this out! You can't expect your customers to run around deleting cookies. Also, when will you finally deprecate the default Named Pipes!? And finally, having that "does not allow remote connections" error spewed out with all connection errors is a really bad design choice, in my opinion.
