Can someone help me with the following problem:
I'm a SQL server DBA and we sell intern SQL-Server resources to the application teams based on needed storage and number of users.
I have several servers shared by different application teams.
Now I'm looking for a method to limit the number of users working together on a specified Database. Because when a project manager wants resources for 100 users I want to be sure that only 100 users can connect to that particular database at the same time.
I know I can limit the number of connections on server level but I need this on Db level too.
The problem that I am having is that with Visual Web Developer I am creating a webpage and having it directly put online, so for example when I start a new ASP.NET page, I select the location to be HTTP, with the location http://MYWEBSERVER/Website and for the language and Visual BasicI notice a couple of things, first that there is no longer a a link under the Main toolbar "Website" selection called the ASP.NET configuration. So how can I configure what I want to have users be able to do? It seems that this choice is only available if I am building the ASP.NET page on my "localhost". So that is the first problem. So I am able to get the pages to work, atleast the things such as the textboxes to show up etc, (Even things as advanced as the "Login" box). How ever when I try to get someone to try to login I am taken to a page that has an server error. The error is: "The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider can not automatically create the database file. " The Stack Trace Errors are at the bottom. I think this is happening because the automatically generated databases are not getting built online as they are on my computer. On my computer I have MSSQL express. So either the databases are not getting built for some reason, (and I think that is the case as I don't see any in the folder). So I think that somehow I have to create a database on my server, and then somehow configure the ASP.NET file, perhaps in the Web.Config file to look for that new database. Is this the correct methodology? Is there some simpler way that I can just somehow upload things as they are and have them work correctly on my server? The error says that either the Server did not find the database or that the trust level was insufficient. I don't think that is it as I just looked again and I don't see any .MDF files. So how would I go about getting this to work right? Is there a way to do this with MySQL also? So that I don't have to use MSSQL? My server only allows 1 DataBase for that. Thanks and I hope my question makes sense. It is basically how can I get it to be able to create and check users etc. online?

I am running this query "delete from ims_domains where id=61" and got the error Maximum stored procedure, function, trigger, or view nesting level exceeded (limit 32)
Please let me know what should be the reason? Thanks, Ravi
I face this error when i try to run my store procedure. The sample of store procedure as following:

Hi all, I get this message when trying to update a tabel i have whichhas nested hierarchies.The current hierarchies beginning from root = 1 are up to the level 5.Before going into details and sample data with all the sql queries andprocedures, this limitation from Microsoft for nested levels .. isthere any way or trick to increase the level in generic?
I have created a delete trigger in Table1 and Table2. Once I delete a certain record in Table1 it will also delete that record in Table2 or vice versa. But once i delete certain record either in Table1 or Table2 it will create an error "Maximum stored procedure, function, trigger, or view nesting level exceeded (limit 32).". Can you help me on this?
I want to perform column level and database level encryption/decryption.... Does any body have that code written in C# or VB.NET for AES-128, AES-192, AES-256 algorithms... I have got code for single string... but i want to encrypt/decrypt columns and sometimes the whole database... Can anybody help me out... If you have Store procedure in SQL for the same then also it ll do... Thanks in advance
I have a stored proc eg spProcA which does not start a transaction
If I call this proc from ado.net code without any transaction around it affecting the isolation level, the isolation level within the proc call is read committed, as expected
If I then call the same proc within a System.Transacstion.TransactionScope with a different isolation level eg Serializable, then i get the expected isolation level in the proc.
However, if i retry the proc without any transaction around it, the isolation level is now the same as the TransactionScope, (eg Serializable), and this persists until either the connection pool clears down (either because it becomes dormant or via an explicit ClearAllPools.
I can resolve this problem by setting the isolation level in every proc (or call to every proc), but i wondered if i am missing something more straight forward?
What is the connection limit of SQL Server express. Currently I am using Access database and it allows < 300 concurrent connections. The database is supposed to be accessed through a web page. If there are hundreds of users hitting the page and updating the database, will there be any synchronization issue. How many concurrent connections can be opened?
I have recently moved over from SQL Server 2000 to 2005 and am now having an issue with my application with what appears to be, the number of recordsets that I can open/close on a single connection.
Here is a snippet of what I'm doing, in VB 2005 using ADO... (assuming the connection is already open and working)
Dim RS1 As RecordSet.
DIM RS2 As RecordSet
RS1.Open("SELECT...")
Do While Not RS1.EOF
count = count + 1
Console.Writeline(count)
RS2.Open("SELECT...")
..some processing...
RS2.Close
Loop
RS2 = Nothing
RS1.Close
RS1 = Nothing
Now as I said this all works fine when I connect to an SQL 2000 server but on SQL 2005 it bombs out when 'count' is approximately 1940 with an exception saying that the login failed. If I have Server Management Studio open, that connection will then freeze and throw up an error about how only one usage of each socket address is normally permitted - I think thats more a red herring though.
Any ideas? I've been through all the server settings and can not seem to find anything about recordset limits or timeouts. The only way I've been able to get around this problem at present is to open a new connection object for each iteration to be used by RS2.
Thanks everyone. Any pointers would be much appreciated.
Hi! when WITH (NOLOCK) statement is used in a select statement, it allows to retrieved data from a set of data locked by another transaction. Is it possible to enforce this at connection level? I mean to open a connection using sqlclient and enforce NOLOCK so that all select statements post to database using that connection are not locked by other transactions. thanks in advance
I need to pass a application userid on every call to my database for triggers on the db to use.
I am connecting to my database using integrated security from my application, all on one windows domain account. However I need to get an application user id over on the connection for triggers to use to stamp in changelogs.
Currently everytime we open a connection we create a #table with the user id in it, but that is expensive, especially in our new SOA where connections are frequently created and dropped on requests.
Is there any way I can get a connection level variable over to the database server so triggers could read it?
This is my code... public partial class test : System.Web.UI.Page {protected void Page_Load(object sender, EventArgs e) {SqlDatabase database = (SqlDatabase)DatabaseFactory.CreateDatabase("ConnectionString");DbCommand command = database.GetSqlStringCommand("SELECT UserName FROM Users WHERE UserID = '6264'"); using (IDataReader reader = database.ExecuteReader(command)) {if (reader.Read()) {lblTest.Text = "test"; } } } }

We have a need for getting data from sqlserver DB on premise to the cloud. DB is not encrypted currently, other applications are accessing it but those applications are on premise. Following link talks about encrypted connection, but is it possible to encrypt only one of the port connection. we can add a custom port.URL...
Hello, I would like to to use SQL Server express, but am concerned about the 4 gig limit
I want to store a lot of data every day and was thinking about creating a database on the fly every time the a new calender month came up.
I have 2 questions: 1. Is the 4 gig limit on an individual DB or on the entire server itself ? 2. Will there be a problem if there were 60 databases (5 years) in the server ?
I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string.
Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value.
Then after spending several hours I found that this is because I have customized the connection string in testCon. If I don't customize the connection string, I am able to enter the "testCon" value in the connection property of the BkpTask.
SELECT prin.[name] [User], sec.state_desc + ' ' + sec.permission_name [Permission] FROM [sys].[database_permissions] sec JOIN [sys].[database_principals] prin ON sec.[grantee_principal_id] = prin.[principal_id] WHERE sec.class = 0 ORDER BY [User], [Permission];
but the results are this: 2 columns - User and Permission
User Permission User1 GRANT CONNECT User2 GRANT CONNECT
IS there a way in SQL Server (2005/2008/2012) to run a script against a Database that will show all users that have permissions to that Database and the type of permissions?

One of our database is approaching the gigabyte size. I know that microsoft claims to support terabyte databases with sql server 7.0. I was wondering if anyone could tell me about the max size of database they have used on an OLTP site without running into problems. ofcourse with SQL Server.
Is there a performance limit on the number of indexes per table / database ? With Filtered indexes there appear to be many more opportunities for more finely defined, and therefore smaller indexes resulting in many more indexes on a single table.
Hi,I am new to SQL express and try to solve the 4GB size limitation.Is there a possibility to create a new database file every time I getto the limit?How can I do that with C#? how can I create new database file everytime it gets full?Can I be connected to two database files at the same time (the full dband the new db)?thanks in advance,oren
I've read here at [URL] that with 32 bit it's recommended to only have 10 database mirrors per instance. However, is there a limit for 64 bit SQL Server 2012?
We're having a problem where we have about 300+ databases and now any new db's we add are timing out when it comes to setting up mirroring and am wondering if this is limited by the instance.
How does one enable sql connections limits for user connections per new and existing databases? how to do it on whole server per database but not set a limit per user.Looks like this must be run on each databases but what if you have 100s of databases:
USE AdventureWorks2012 ; GO EXEC sp_configure 'show advanced options', 1; GO RECONFIGURE ; GO EXEC sp_configure 'user connections', 325 ; GO RECONFIGURE; GO
Hi! After upgrading SQL Server from 6.5 to 7.0 my production database compatibility level is "65". I checked that by executing sp_dbcmptlevel <database_name>. I can change it to "70" but my question is how it's going to affect the application and do I have to change it?
