Named SQL 2005 Instance Multiple Active Recordsets-C# Stored Procedure-Connection String
May 7, 2008
I am working on a C# stored procedure for SQL 2005, and i've uncovered a couple questions.
First a description of the procedure:
I have a series of equations taking place to calculate a score based on activities in which the user participated in, that will give them an over all grade or rating. The calculations currently take place in the database, and I am moving this from T-SQL to C# CRL.
1. In order to connect the stored procedure to the database I use a SqlConnection and a SqlCommand to execute either dynamic sql or a stored procedure to return data to a data reader. Is there an easier way to connect to the database? In SSMS if i open up the query it knows what database i am connected to. Do I have to make a sql connection in C# stored Procedures?
2. I have multiple functions within the main C# Stored Procedure that I'm working on. This ends up requiring Multiple Active Recordsets. I must set this withing the connection string. Seeing as I'm using a named instance of SQL 2005, I now must put the userid, password, and server name into the code. Is there a more secure way to connect to SQL Server in a C# Stored procedure that allows MARS?
3. I encryped the connection string, and put it into the assembly, I wrote a decryption class, and in the procedure itself everytime I need to refrence the connection string, I call it, decrypt it, and pass it along. But my code to decrypt the connection string is in the compiled DLL, if the server was ever compromised the encrypted connection string and the key to decrypt it are sitting in the DLL. Is there a config file that I can use for C# Stored Procedures?
4. If I have to keep the connection string in the file, then I need to change that per environment. Example I have 3 test environments before production. So I would need to change the connection string for each file. That may be fine for one procedure, but what if I have 20, that will quickly get of hand?
5. Along the security lines, can the assembly for a C# Stored Procedure be called from outside the assembly? From a command prompt, or by a maliceous program? Or could it be called directly by a .NET application instead of going through a T-SQL Stored Procedure that is using
WITH EXECUTE AS CALLER
AS
EXTERNAL NAME [PROJECTNAME].[CLASSNAME].[METHODNAME]
The box I am trying to connect to is running two instances of SQL Server. There is a SQL Server 2005 instance which is the default. There is a SQL Server 2000 instance which is named 'SQLSERVER'. I can connect to the SQL Server 2000 instance no problem:<add key="ConnectionString" value="server=MYPCSQLSERVER;database=mydatabase;user id=****;password=****" /> However, I am having trouble connecting to the Default SQL Server 2005 instance. I have tried: <add key="ConnectionString" value="server=MYPC;database=mydatabase;user id=****;password=****" /> but it doesn't work. I have tried explicitly setting SQL Server 2005 to use port 1434 (as SQL Server 2000 is running on port 1433), and then used: <add key="ConnectionString" value="server=MYPC,1434;database=mydatabase;user id=****;password=****" /> but this doesn't work either.
Am I mssing something here? Any help much appreciated Thanks...
Hello, I had started my project with the express edition, then I switched to the pro one. The problem is that in my webconfig I still have .SQLEXPRESS and I don't know how to modify that to use the full version of Sql server. <add name="MyConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|MyDataBase.mdf;Integrated Security=True;User Instance=True"providerName="System.Data.SqlClient" /> When I look at the surface area manager I can see that I have 2 instances running : MSSQLSERVER and SQLEXPRESS.When starting Sql Server Management Studio I can connect to 2 servers: NEWDELL and NEWDELLSQLEXPRESS.And when I try to replace SQLEXPRESS by MSSQLSERVER in the connectionstring, then it doesn't connect.I remember having lost connection already when playing with all these tools, so I pay attention now ! That's why any help would be really appreciated ! Thank you.
I think I'm being a bit thick, but I just cannot figure out the proper syntax to call a stored proc on a SQL named instance I have. I've tried many variations, but here is the basic format of what I'm trying:
EXEC ServerInstance.DB.dbo.usp_fm_proc 1
It seems it doesn't like the as I get an error "Incorrect syntax near 'Instance'.
I'm writing a java application that queries sqlserver 2005 (and 2000). In case the sql browser service is stopped I need to use the named pipe property or the port property, right? But how could the program know at runtime what is the port and what is the pipe name? And how should a connection string to sqlserver 2005 (and 2000) that includes named pipe, look like?
Hi, I am struggling connection to a named instance of SQL 2000 (SP4) from another machine but without any success. I get an error message saying that the server does not exist or access is denied.
The security configuration in this named instance is the same as the default instance (also 2000) and the remote machine can connect to it successfully.
I also configured the aliases in Client Network Utility in the client machine and set the server (machine) name and the port number used by the instance - but no help.
I use osql and Query Analyzer to connect to it, but I cannot connect by any of them.
Connecting locally, in the machine where the instance is installed, is successful.
The same behaviour appears when I try to connect to another instance on the machine which is 2005. Something with the named instance is problematic.
If i initially installed SQL Server 2005 Developer Edition using the "default instance", how do i create an additional (new) SQL Server 2005 (90) "named instance" without reinstalling SQL Server 2005?
Several applications in out environment use Microsoft access to access the SQL server databases. Our new SQL Server 2005 instance is a named instance. We would like to create a .reg file to update the individual workstations as part of the migration. For some reason the .reg file with a named instance does not work. If the entry is created through the GUI it works. The server drop down does not show the named instance, only the server name but if you type the servernameamed_instance it finds it ok. Here is an example of what works and what does not. Any ideas on what the problem might be?
Windows Registry Editor Version 5.00 - Does NOT work
I got the following error using either NT or SQL Login ('sa') that are sysadmin in my SQL 2005 instance:
Your Account information could not be verified for one or more instances. Ensure that you can connect to all the selected instances using the account information provided. To process further deselect the instances to which connectivity cannot be established.
However, I would login to SQL 2005 named instance, either NT or SQL login 'sa' without any problems to do anything I want because both are sysadmin.
<PS> Note that my default SQL instance in my local server is SQL 2000 and SQL 2005 named instance.
I€™m creating a new named instance in SQL2005 , by default the instance created with €œLatin1_General_CI_AS€? collation.
I want to change this collation to €œSQL_Latin1_General_CP1_CI_AS€?, but sincerely I don€™t have a clue how to select it on the collation setting window :
Is there a sample way to define string constant which every stored procedure can use in SQL 2005 ? 1. In stored procedure A, there is select a1,a2,a3,a4 from mytable where usename='qaz'2. In stored procedure B, there isselect a1,a2,a3,a4 from mytable where VisitNumber>33. I hope there is a sample way to define string constant such as: constant mystring='a1,a2,a3,a4'4. So I can use this string constant both stored procedure A and stored procedure bsuch as:select mystring from mytable where usename='qaz' select mystring from mytable where VisitNumber>35. How can I do that? is there a sample way? Mnay Thanks!
I've two instances(Default, Named[dynamicsFINANCE]) running on SQL server 2014. However, when I try to connect to named instance say (dynamicsFINANCE) using SQL authentication from local SSMS, I get below error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
I assigned a static port number to the named instance [dynamicsFINANCE] 1450. I also setup the firewall rule to allow access to Port 1450.
I have a 3 node cluster on which I have installed SSAS as it's own insntance. I have created this as a named instance and can connect to it by serverinstance if I'm on the server itself. However from my desktop I get the error saying instance was not found on server name.
I have defined an alternate port and setup firewall rules and can connect via server:port but not serverinstance. Prior to making this change SSAS was running on default port of 2383 and I could connect just by servername.
I have read many articles for previous versions saying that clustered SSAS will always use 2383 and that you must connect just using servername. However and this is were it gets strange. I have a 2 node UAT cluster with SSAS setup exactly the same way I've described above and I can connect from my desktop as serverinstance.
Should I be able to connect as serverinstances for a named clustered instance in 2012 ?
Hi, I have a task in hand to migrate (upgrade) from SQL2K named instance to SQL2K5 default instance. There are many intranet applications touching current SQL2K. I would like to perform this upgrade such that I don't have to touch any application code - meaning I don't have to change the connectionstring to point to new Default instance. How can I achieve this?
So, in otherwords, here is what I want to achieve:
Current Server: SQL2K: SERVER_AINSTANCE_A (named instance)
If I have both default, I could achive this by setting up DNS alias after migration done so that any call for SERVER_A would point to SERVER_B. But in my case, I don't have SERVER_A, I have named instance. Is there any solution?
Whenever I use "User Instance=True" as in the connection string below, I get an invalid connection string error. If I take it out, the connection string generates other errors.
I am trying to set up a Named Instance of SQL 2000 on the same machine that has a default instance of SQL 7.0. The setup always completes and I am able to register the Named Instance of the SQL Server with which it was installed on. However, when I try to connect the users to the database, with both windows and SQL authentication, I receive a SQL server not found error. I have tried an alias setup as well as physically specifying the port number in settup up an ODBC connection. Has anyone ran into similar problems? Also, has anyone been able to successfully complete the process as mentioned above?
I have a server with sql server 2005 installed as the default instance -- I have a piece of software that needs SQL2000 to be the default instance. Is there a way other than install new sql2005 named instance and move databases to rename my SQL2005 instance from <machinename> to <machinename>sql05 for example?
Problem about pass a big string (over 8000 characters) to a variable nvarchar(max) in stored procedure in SQL 2005! I know that SQL 2005 define a new field nvarchar(max) which can stored 2G size string. I have made a stored procedure Hellocw_ImportBookmark, but when I pass a big string to @Insertcontent , the stored procedure can't be launch! why? create procedure Hellocw_ImportBookmark @userId varchar(80), @FolderId varchar(80), @Insertcontent nvarchar(max) as declare @contentsql nvarchar(max); set @contentsql=N'update cw_bookmark set Bookmark.modify(''declare namespace x="http://www.hellocw.com/onlinebookmark"; insert '+ @Insertcontent+' as last into (//x:Folder[@Id="'+@FolderId+'"])[1]'') where userId='''+@userID+''''; exec sp_executesql @contentsql;
as declare @contentsql nvarchar(max); set @contentsql=N'update cw_bookmark set Bookmark.modify(''declare namespace x="http://www.hellocw.com/onlinebookmark"; insert '+ @Insertcontent+' as last into (//x:Folder[@Id="'+@FolderId+'"])[1]'') where userId='''+@userID+''''; exec sp_executesql @contentsql;
Currently I am trying to connect to SQL Server 2005 via Excel VBA. I would like to create a connection to the server as I have previously done with my 2000 server. However, the diffence this time is that I am using Active Directory so there are no specific log-in's for SQL per se just Windows Users that are part of groups, any of which could use this spreadsheet. So where-as previously I included the username and password for SQL Server in the connection string I would now like to use the credentials currently logged onto the particular machine.
My previous code was this
Public Function getConnection() As ADODB.Connection
' Create a connection object. Dim Conn As ADODB.Connection Set Conn = New ADODB.Connection
' Provide the connection string. Dim strConn As String
'Use the SQL Server OLE DB Provider. strConn = "Network Library=DBMSSOCN;PROVIDER=SQLOLEDB;"
'Connect to the Pubs database on the local server. strConn = strConn & "DATA SOURCE=SQL02,1433;INITIAL CATALOG=dbDataWareHouse;"
'Use a login. strConn = strConn & " Uid=*******;Pwd=******;"
'Now open the connection. Conn.ConnectionString = strConn
Conn.Open
Set getConnection = Conn
End Function
Would anyone be able to point me in the eight direction ? Your help would be much appreciated
I installed SQL Server 2005 recently on a cluster. I didn't go for the default instance and instead I named the instance option. Now I would like to migrate everything from the named instance to the default instance, which I haven't yet installed.
Is this an easy process? What about the logins and the maintenance plans and jobs? Is there anything else I need to be aware of?
I've never had to do this, but when I downloaded the Web Workflow Approvals Starter Kit, it requested that I install the database into a User Instance of .SQLEXPRESS.
Now the problem is, I've installed it onto a default instance, so I was wondering whether you can create a named instance on top of a default instance... and if so, how would you do that?
Hello,I need a permanent synchronization between the "Active Directory" and the UserTable in my WebApp.I think a good solution for my interface can I realize with the "Stored Procedures" in SQL Server 2005. Is this the right way?I can create a Stored Procedure and a AD-Reader separately, that's no problem. But how I can import the "System.DirectoryServices"-Assembly in my Stored Procedure?Or is there an other solution?Thanks a lot!NussyStar*
I am newbie in SQL Clustering. I have set up a Windows Server Cluster with 2 nodes and am having the following problem with Physical Disk resource for cluster groups:
My Default Cluster Group (named Cluster Group) has IP Address, Network Name, Physical Disk and MSDTC resources. In addition to that my Default SQL Server instance resources are also in this group. I had this initial set up for Active/Passive mode.
Now I am trying to set up a SQL Cluster in Active/Active mode. For this I have to install another instance of SQL Server in the existing cluster and make a separate cluster group for its resources. I made a new cluster group (SQL Instance Group) with an IP Address and a Network Name resource for this new instance but I dont have any Physical Disk resource to allocate to it. As such while installing the SQL Server Instance I get stuck when I'm asked to select the quorum disk to be used.
Is it possible to configure two quorum disks, one for each group? What's the concept of dedicated disks resource for each sql instance in a group? Is this same as the quorum disk? If this is not a shared disk how do I configure a dedicated disk resource for my second cluster group (SQL Instance Group)?
Using just SQL (within SQL Server 2000), I'm looking to output 2 (or more) recordsets from a one-to-many join between table all on one row. Help! Can someone please show me how to do this if it can be done.
SELECT - i.itemID AS ItemID, - p1.partID AS HLPartID, - p1.manf AS HLManf, - p1.name AS HLName, - p2.partID AS TLPartID, - p2.manf AS TLManf, - p2.name AS TLName
FROM - ZItems i - - - - INNER JOIN ZItemsToParts ip - - - - - - ON i.itemID = ip.itemID AND - - - - - - (ip.funktion = 'headlight' OR - - - - - - ip.funktion = 'taillight') AND - - - - - - i.itemID = 10 - - - - LEFT OUTER JOIN ZParts p1 - - - - - - ON ip.partID = p1.partID AND - - - - - - ip.funktion = 'headlight' - - - - LEFT OUTER JOIN ZParts p2 - - - - - - ON ip.partID = p2.partID AND - - - - - - ip.funktion = 'taillight'
************* Output *******************
Using "Query 1" I get this: (Note: HL = Headlight; TL = Taillight)
I wish to output the proceeding two record set in one row Any ideas how this can be done with SQL Server 2000 (with JOINS in the FROM clause)? - DESIRED OUTPUT:
I am doing some mods to an existing db web app in asp. I am providing a facility to copy a subset of related records in a few tables. I am using one recordset to read in the selected records and then copying the data into another recordset creating a new record in the same table. I have to then pick up the @@IDENTITY of the new record so that I can update linked records in other tables.
The @@IDENTITY value returned is null unless I close the selection recordset.
I have created a simplified version of the code to demonstrate this.
The underlying table is called 'test' and it has 2 fields, 'test_id', integer, identity and 'test_desc' varchar(50)
ASP Code
<% dim objConn, objRS1, objRS2, objRS3
sub OpenDatabase() 'open database object here instead of in page Set objConn = Server.CreateObject("ADODB.Connection") 'Connect object to database through global.asa application variable objConn.Open = Application("test_ConnectionString") 'Create recordset object to use Set objRS1 = Server.CreateObject("ADODB.Recordset") Set objRS2 = Server.CreateObject("ADODB.Recordset") end sub
sub CloseDatabase Set objRS1 = Nothing Set objRS2 = Nothing objConn.Close Set objConn = Nothing end sub
function UnNull(numval) if isnull(numval) then UnNull="NULL" else UnNull=cstr(numval) end if end function
OpenDatabase
strSQLQuery = "select * from test where test_id in (1,2) order by test_id" objRS1.Open strSQLQuery, objConn, 1, 3
do while not objRS1.eof objRS2.Open "test", objConn, 1, 3 objRS2.AddNew old_test_id = objRS1("test_id")
Hi, I'm trying to publish an SQL Server Instance through an ISA Server but I'm not being able. I tried to create the rules to allow the SQL protocols and to tunnel the calls from internet into my SQL server. I set the instance to connect through a fix port so it wouldn't worry about not being the default instance and configured that port in the ISA server so the remote calls were channeled into it. I'm allowing only TCP connections. I must be pretty wrong on something because it doesn't work. Can someone offer me a white paper or some step by step instructions to do this? Thanks a lot.
If you were asked to install SQL 2005 on a machine, would u install a default instance or a named one? And why would u choose one over the other?? Also, r there any issues with using a default instance?
