hello friends..I got this error while conecting to sqlsever 2005 through Visual studio 2005
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

I have just suggested here http://www.codeproject.com/script/comments/forums.asp?msg=2175289&forumid=1725#xx2175289xx[^] to check if the machine where the SQL Server is located has any firewall active.

Do a google search and you'll get plenty of hits

http://www.google.co.uk/search?hl=en&q=sql+server+express+enable+remote+connections&meta=[^]

pick a likly looking one and work through what it says

If your not using Express then say what edition you are using. If you have already enabled remote connections then say so.

I write connection string as
string str="server=pcname/SQLEXPRESS; Initial Catalog=databasename;user=username;password=password ";
Is it right. I am using sql server 2005 express edition

Could you try:

"data source=PCName\ServerName;initial catalog=DBName;User ID=Username; Password=Password;"

and see what happens?

I tried it ..But the result is the same...I also allow remote connections through TCP/IP in sql server configuration manager..

you are using wrong connection string
Use this..

Data Source=REMOTE_SQL_SERVER;Network Library=DBMSSOCN;Initial Catalog=MY_DATABASE;User ID=MY_DB_USER;Password=MY_USER_PASSWORD;

Server Error i need to solve this error

Well the connection string I gave works perfectly for me. However, it would be interesting to try the SSPI thing:

"data source=PCName\DBServerName;initial catalog=DBName;Integrated Security=SSPI"

Hi John

In this case, I normally do a bulk insert into a temporary table then run the following to update existing records:

update MMT set
    Value1 = T1.Value1,
    Value2 = T1.Value2,
    LastUpdateDate = GetDate()
  from MyMainTable MMT
  inner join #MyBulkInsertTable T1
  on T1.Id = MyMainTable.Id
  where T1.Value1 <> MMT.Value1 or T1.Value2 <> MMT.Value2

The where-clause ensures that you only update records that have changed. If the Value1 and Value2 columns can be null then I normally use the IsNull function to force a value in the comparison.

And the following to insert new records:

insert into MyMainTable
  select T1.Id, T1.Value1, T1.Value2, GetDate() as InsertDate,
      GetDate() as LastUpdateDate
  from #MyBulkInsertTable T1
  left outer join MyMainTable MMT
    on MMT.Id = T1.Id
  where MMT.Id is null

This uses an outer-join to identify rows that have not yet been loaded. The "InsertDate" and "LastUpdateDate" columns provide a primative audit trail that can be useful when things go wrong.

A similar technique can be used for deleting records from MyMainTable.

Hope that helps.

Andy

Is the SQL Server 2005 you are trying to access on another machine? Because if it is, you might be having a firewall on that machine which is preventing your code from access the database server.
