Need Help - Converting OLEDB Connections To SQL Connections In
Hi there,
        Here we have got a application that was developed when database was
sitting on SQL server 6.5. Now client has moved all of their databases
to SQL server 2000. When the database was on 6.5 the previous
development team has used oledb connections all over. As the databases
have been moved to SQL server 2000 now i am in process of changing the
database connection part. As part of the process i have a login
authorization code.
Private Function Authenticate(ByVal username As String, ByVal password As String, ByRef results As NorisSetupLib.AuthorizationResult) As Boolean
Dim conn As IDbConnection = GetConnection()
Dim cmd As IDbCommand = conn.CreateCommand()
Dim sql As String = "EDSConfirmUpdate" '"EDSConfirmUpdate""PswdConfirmation"
'Dim cmd As SqlCommand = New SqlCommand("sql", conn)

cmd.CommandText = sql
cmd.CommandType = CommandType.StoredProcedure
NorisHelpers.DBHelpers.AddParam(cmd, "@logon", username)
NorisHelpers.DBHelpers.AddParam(cmd, "@password", password)
'Get string for return values
Dim ReturnValue As String = cmd.ExecuteScalar.ToString
'Split string into array
Dim Values() As String = ReturnValue.Split(";~".ToCharArray)
'If the return code is CONTINUE, all is well. Otherwise, collect the
'reason why the result failed and let the user know
If Values(0) = "CONTINUE" Then
Return True
results.Result = Values(0)
'Make sure there is a message being returned
If Values.Length > 1 Then
results.Message = Values(2)
End If
Return False
End If
Catch ex As Exception
Throw ex
If (Not conn Is Nothing AndAlso conn.State = ConnectionState.Open) Then
End If
End Try
End Function
''' -----------------------------------------------------------------------------
''' <summary>
''' Getting the Connection from the config file
''' </summary>
''' <returns>A connection object</returns>
''' <remarks>
''' This is the same for all of the data classes.
''' Reads a specific
connection string from the web.config file for the service, creates a
connection object and returns it as an IDbConnection.
''' </remarks>

Dim conn As IDbConnection = New System.Data.SqlClient.SqlConnection
conn.ConnectionString = NorisHelpers.DBHelpers.GetConnectionString(NorisHelpers.DBHelpers.COMMON)
Return conn
End Function
in the above GetConnection() method i
have commented out the .net dataprovider for oledb and changed it to
.net dataprovider for SQLconnection. this function works fine. But in
the authenticate method above at the line
Dim ReturnValue As String = cmd.ExecuteScalar.ToString

for some reason its throwing the below error.
Run-time exception thrown : System.Data.SqlClient.SqlException - @password is not a parameter for procedure EDSConfirmUpdate.
If i comment out the
Dim conn As IDbConnection = New System.Data.SqlClient.SqlConnection
and uncomment the .net oledb provider,
Dim conn As IDbConnection = New System.Data.OleDb.OleDbConnection
then it works fine.
I also have changed the webconfig file as  below.
key="Common" value='User ID=**secret**;pwd=**secret**;Data
Source="ESMALLDB2K";Initial Catalog=cj_common;Auto
Translate=True;Persist Security Info=False;Provider="SQLOLEDB.1";'
<add key="Common" value='User ID=**secret**;pwd=**secret**;Data Source="ESMALLDB2K";Initial Catalog=cj_common;' />
Please help. Thanks in advance.

Help - Server Stops Responding To Connections, Stops Accepting Connections
I've been having the same problem for 2 weeks now. If anyone has anyideas, I'd love to hear them. We are using both SQL and WindowsAuthentication. I was running a Profiler Trace at the time, and amgoing through it now but have not seen anything yet.Thanks in advance.About once a week, at no fixed time (but so far, between 8am and11am), my SQL Server 2000 on Windows 2000 (8.00.679) will stopresponding. New connections will at first take forever to connect,then an error message about the PreLoginHandshake(). We have to killthe service (read below) to stop it, but it comes back withoutproblems.The very first time this happened, I got buf latch errors in the SQLError Log, but not this time. (However, the first time we waited forabout 5 minutes after it stopped responding , and then the buf latcherror message showed up. This time we restarted the services before 5minutes had passed.)The SQL log shows nothing abnormal. The SQL Agent log shows nothingabnormal. The Event Log shows nothing abnormal. Stopping the servicethrough the SQL Service Manager doesn't work - we have to go into theServices control panel, stop the Agent then stop the service, and whenthe service says that it cannot be killed, we then run the "kill"command on it (from the resource kit, I believe) and it stopsimmediately. Once this occurs, we can use the SQL Service manager tostart everything up successfully, with no problems in the logs.Note: we have not rebooted the server yet, juststopped/killed/restarted the services. We plan on rebooting thisweekend.Timeline:10:20 - an openquery job runs successfully - as far as I know,everything is okay at this point.10:22 - for some reason, a transaction log backup job does not run(ran successfully at 10:02, runs every 20 minutes.). That timedoesn't show up at all in the Job History for that job, nor is there alog file, nor was a report txt file generated.10:29 - openquery job 1 fails to run. Connections are sluggish, butopen connections can run queries.10:30 - openquery job 2 fails to run. (not the same query as 1 or 3)Connections are sluggish, but open connections can run queries.10:30-10:40 Enterprise Manager cannot connect - stuck duringconnection. This is the case on multiple machines, as well as on theserver. My Enterprise Manager doesn't respond, and I cannot start anew instance. "Select getdate()" can take several seconds to run, andI get a "Lost connection" error.10:40 - openquery job 3 fails to run. Profiler shows my openquery jobwas the last thing run - no further profile messages for the next 2-3minutes.10:43 - We start shutting down the server.

Keep A Few Connections Open All The Time Or Open/close Connections On The Fly?
Just a quick question about connection management. My application willnever need more than 1 or 2 connections about at any given time. Also, I donot expect many users to be connected at any given time. For efficiency, Iwould like to keep connections alive throughout the lifetime of the objectsrequiring them, rather than opening a new connection, executing code andthen closing it again. What is the most efficient way of doing this?Should I perform the open/close or just one open when I create the objectand a close when I dispose of it?

Some Ms SQL Connections
Hi I have some simple questions of for MS SQL. Say I have a database with a table Called Company. In this table I have Employee's with these columns(EmployeeID<PK>, FirstName, LastName) Now I am inserting some data like this.EmployeeID  FirstName, LastName------------------------------------------------------- 1                  Bob            Smith2                  Joe               Mitter Now Say I have this situation(this will look weird for this example but for another examples and the stuff I am working on it make sense). Say I have a new Employee Called Jessica White. Jessica must be the second record. So I need to insert it between the 1st and 2nd record. Like I said I am very noob at doing this stuff so I am not sure how I would do it. I first was going to my table and then went to modify. This brought up a blank grid with all my column names. I then started to add all my data in. I found out later to make my life easier I need to enter in certain spots null rows in it to help with formating(otherwise I would have had to figure out a way to do make null rows with c# code). I then went back to this grid and I tried to add a record before the data just like you if you used excel. I quickly found out you can not do that. This resulted me having to recreate the table and reput the all the data back in(this told me I was doing something very very wrong). I was then thinking of writing it with a query and I been playing around with it and still running into problems like say I had a table called test with a coloum called id<PK> and testss(yes bad names just playing around though).So if I did something like this:INSERT INTO testVALUES(2)INSERT INTO testVALUES(1)SELECT * FROM testNow I am trying to figure out how to insert something between rows 1 and 2. Would I have to drop the table or delete all the data and then run a saved copy of my script with the added change or what?My second question is what is a good site that has examples of all the commands(I don't want to read a book on it I have had a oracle sql course and well it was just boring and I did not learn too much.). I think the best way for me to learn is just continue doing my site and picking it up on the file and when I got a problem read about it and ask on the forums.   Thanks

SQL Connections With VB.NET
As most of you are aware, when you close a VB.NET connectrion to a SQLserver, the connection doesn't actually drop right then and there.From my tests, using VB.NET 2003 and SQL2K, the connection doesn'ttimeout and drop off for 6 1/2 minutes. How can one force thisconnection to immediately drop off with code?

Too Many SQL Connections
We have a case where a user is using Excel sheet to connect the database on SQL2K and generally his connection runs in the upper 150 in numbers. He generally gets more than 150 connections open.

I know that it's not a good thing, but is there a way to limit it or even kill it after it reaches max?

What are the disadvantages of opening too many connections?

Out Of Connections... Or Am I?
I'm getting the classic message "The timeout period elapsed prior to obtaining a connection from the pool" etc when connecting to my SQL Server 2005 Express from a .Net application.
Then I try connecting, simultaneously, from a simple thing I wrote just for testing and this works fine. So, then the connection pool can't be full, can it? Or, does each application have its own pool??

SQL Connections
We use linked servers to run distributed transactions across servers and am having problems with hung connections. Server A runs a distributed
transaction out to servers C, D, & F. If server A experiences any time out issues with servers C, D, or F when it is writing records the connections are
dropped on servers C, D, or F but on server A it does not. I have to reboot the server to drop the connection so the process can run again.
The process is a stored procedure that is run in a job and handled through by job scheduler but trying to stop the job does not work nor killing the process using the
kill command. Any one have any suggestions on what I could try to resolve this problem? Thanks in advance

SQL 7 Connections
Very strange event. Installed new machine into NT 4 network, which has a PDC and a BDC. We have copies of all SQL databases on both the PDC and the BDC. I installed SQL 7 on new workstation. Throught Control Panel/ODBC connections I can reach the SQL files on bith the PDC and BDC. Howver when I try to use Enterprise Manager, I can connect to the tables on the PDC, but not the BDC. SQL lists both machines in the server group, but only allows me to access tables on PDC! Here is the Event information that I recived on the BDC:

The computer IVR1 tried to connect to the server NTBACKUPSERVER using the trust relationship established by the MASSCOM domain. However, the computer lost the correct security identifier (SID) when the domain was reconfigured.

How do I fix this?

anyhows, my place of work have goldmine 6.7 running on a server. the problem is that some of the client machines seem to be taking 2 connections to the server when logged into goldmine and some only 1.

when looking at the open sessions it shows a second for some users accessing pipesqlquery. all users show this but only some show it as a second connection.

Help With Connections
Hi everybody,

I need a little help...

I created several packages, that after their creation should not be changed again; that's why I created a Package Configuration File in which I set all the Connections I need, so that this is the only file I have to modify.

I set there also the path of the connections for my log file and for my error files (which are both text files), but if I change their paths in the configuration file this change doesn't affect the package, and the path of the log remains the same.

That's an image of one of those packages....

The fact is that I cannot change the ConnectionString of the connection called "log_pkg", but it always remains the same...

How can I resolve this problem??

Thanks everyone

SQL Connections

This might not be the right forum, but I'll go ahead and ask anyways -

How does SQL server's per seat/user licensing work ? What I'm hoping to find out is that - if some one has procured a 2 user/seat license - will the number of connections that the two users are allowed to open be limited to 2 ?

Or can the two users open any number (reasonable number)of connections ?I'm asking this in the context of the possibility of having multiple connections service our desktop application. Or am I tied to having a maximum of one connection per client/user by virtue of the licensing restrictions ?

Best Practice For SQL Connections And Asp.Net
We have developed as quite simple ASP.Net webpage that fetches a number of information from a SQL 2005 database. We are having some problems though, becuase of a firewall that is beetween the webserver and the SQL server, and I think this is because of bad code from my part. I'm not that experiensed yet, so I'm sure that there is much to learn.
Usualy when I do a query against a SQL database, I do something like this:
Function GO_FormatRecordBy(ByVal intRecordBy As Integer)        Dim dbQueryString As String        Dim dbCommand As OleDbCommand        Dim dbQueryResult As OleDbDataReader        dbQueryString = "SELECT Name FROM tblRegistrators WHERE tblRegistratorsID = '" & intRecordBy & "'"        dbCommand = New OleDbCommand(dbQueryString, dbConn)        dbConn.Open()        dbQueryResult = dbCommand.ExecuteReader(CommandBehavior.CloseConnection)        dbQueryResult.Read()       dbConn.Close()        dbCommand = Nothing        Return dbQueryResult("Name")    End Function 
Now, lets say that I have a DataList that I populate with Integer values, and I want to "resolve" the from another table, then i do a function like the one above. I guess that this means that I open and close quite alot of connections against the database server when I have a large tabel. Is there any better way of doing this? Chould one open a database connection globaly in lets say the ASA fil? Whould that be a better aproch?
When I added the CommandBehavior.CloseConnection to the ExecuteReader statment, I noticed that it was a bit faster, and I think there was fewer connections in the database, so maby there is more to the "closing connections" then I usualy do.
Any tips on this?
 Best reagrds,Johan Christensson

 Hi all, In a select sql statement, I have to query 2 databases from 2 different servers. The only way I found to do this, is to call OPENDATASOURCE like this :<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:bdConnectionString1 %>"        SelectCommand="SELECT * FROM [Table1] t1 left join OPENDATASOURCE('SQLOLEDB','Data Source=servername;Initial Catalog=xxx;Persist Security Info=True;User ID=xxx;Password=xxx').dbname.dbo.table2 t2 on =">    </asp:SqlDataSource>My question is the following :Is there a way to connect to the second server without using the full server declaration into the sql statement ? For information, the server connection is already declare into my web.config like that :<add name="bdConnectionString2" connectionString="Data Source=servername;Initial Catalog=xxx;Persist Security Info=True;User ID=xxx;Password=xxx"   providerName="System.Data.SqlClient" />so is there a way to use 'bdConnectionString2' directly ?If not, is there a way to connect to the second server without entering informations like User ID and Password ? My problem being that I'm not sure it's safe to send this informations directly from the page. Thank you

Reusing Connections
Every time my app needs to open a connection, it tries to establish a new connection with the mssql server. I´ve already set the max pool size property in the connection string. After that, my app raises an "time out"error saying it couldn´t obtain a connection from the pool. The problem is that I have a lot of iddle connections. With the Enterprise Manager I can see the status of the connections. They´re all the same "awaiting command". How can I reuse this connections? I know that the connection string must be the same for all connections and it is. I´ve set it in the web.config file. If I remove the max pool size property from the connection string I get a lot, I mean A LOT of connections with the sql server. Any ideas?

Updating A Row With The Right Connections

I have a database with two tables:


The Appointments table stores date/time for an appointment as well as the 'member' (or customer) that is attending it.

The Notes table stores the notes entered after an appointment and is linked to the Appointment table by an 'appointment' field. There is also a 'new' field to show if the Notes have been read or not.

I need to be able to set the 'new' fields in Notes to 0 for all appointments that relate to, say, member 6.

I'm sure its a simple SQL process, but I don't know it.

I tried:

UPDATE Notes, Appointments SET WHERE Appointments.member=6 AND Notes.appointment=Appointments.ref

But it doesn't like this.

What is the correct format?

Sleeping Connections

I have written an application in VB6 connecting to a SQL Server 2000 database using ADO. This app is running on the same computer as SQL Server.

What I am seeing now is that each day 2-3 new connections are being created by SQL and these connections have a "sleeping" status and "AWAITING COMMAND" command. Also, when double-clicking a
connection, it's last TSQL statement is empty... This way, connections are piling up.

Does anyone have an idea why this is happening and what I can do to avoid this ? Also, how can I determine what is causing this ?

Many thanks,

Hi, I have a VB application running on SQL Enterprise Edition. Physically there are only 20 users loging in to the software at one time. However i can see more that 12 SPIDs for each user. The developers have been opening a new connection for each form in the application i guess. Is it normal or is there any specific requirement that foces them to do so? Shall i need to change the default WORKER-THREADS option on the server for peformance? Suggestions please!!!
