SQL Server :: Unable To Add A Connection To Database (SQL Server 2008) Using The Server Explorer
Aug 13, 2010This issues has been driving me nuts. I am trying to follow the tutorial on [URL] I am trying to connect to a database in Microsoft SQL Server 2008. The way I do this is by right clicking on the "Data Connections" > Add Connection. Afterwards the Add Connection window comes up, I make sure my data source is "Microsoft SQL Server (SqlClient). And, I choose a server name; the only server I can choose is DomainSQLEXPRESS. The issue is when I go down to the "Select or enter a database name" drop down box, I do not see my database listed. I have also made sure in the SQL Server Management Studio that I have given my user all the privileges for the database. I know my explanation is kind of vague, but would anyone know the reason why I would not see my database?

View 2 RepliesSQL Server :: Accessing Database Without Using Connection String In Web.config
Aug 2, 2010To give some background details, I have created a website for a friend that has a few pages that require a database in the background. I've used Visual Studio templates for most of it, so there's the standard ASPNETDB.MDF file that's created for users and groups, a login page and a page to view and manage those users etc etc. The login page uses the standard controls for logging in, retrieving lost passwords and so on. Being standard controls, by default they get the connection string from the web.config file. Upon attempting to upload the site to my host (1and1.co.uk in case anyone else has any dealings with them) I discovered that storing the connectionstring doesn't work. 1and1 support say that the sql databases can only be accessed using scripts like this (this is an example of theirs):
<html>
<title>Queries from the MS-SQL database with ASP</title>
<body bgcolor="FFFFFF">
<h2>Query from table <b>products</b> with ASP</h2>
<%
Set conn = Server.CreateObject("ADODB.Connection")
conn.open "PROVIDER=SQLOLEDB;DATA SOURCE=mssqxxx.1and1.com;UID=dboxxxxxxxxx;PWD=xxxxxxxx;DATABASE=dbxxxxxxxxx"
'This code block will create a recordset
Set rs = Server.CreateObject("ADODB.Recordset")
SQL = "select * from products"
rs.open SQL, conn
'will iterate to display the records got from the database
While Not rs.EOF
response.write(rs("id") & " " & rs("price"))
rs.MoveNext
Wend
'closes the connection
rs.close
conn.close
Set rs = Nothing
Set conn = Nothing
%>
</body>
</html>
So my question, is it possible to get the standard asp.net controls to access a database through a script like this?
SQL Server :: Connection To Database Expires Causing An Error?
Aug 9, 2010I have an asp.net web page which works with a database. When I first upload it I never disposed the connections so after using the different modules of the application for sometime it would suddenly stop working saying the connection pool filled or something like that.To fix it when a user clicked a button I opened the connection, tell the database what I needed and finally disposed the connection.
This seemed to fix everything, in fact you can work with application all you want, the problem comes if you stop using it for certain time.So for instance, I have a module in my webpage where user can capture information for a certain product. When the user clicks in one button the info gets into the database. If the user is continuosly capturing data everything works fine, but if it goes for about 10 min when he clicks the button he will receive an error. To fix this the user has to log-in again.
Every module opens a connection to the database to verify the user identity, but then after it verifies it I dispose the connection so I don't think there is a problem.

SQL Server :: Database Deletion Not Working When Parameter Involved?
Sep 2, 2010I have a system in which users can enter records into a database via ajax. Each user may hold many values in the database, with different pageId and itemId values. Each user is identified by a GUID set to a cookie. The system needs to prevent the user from entering two pieces of data with the same pageId and itemId, so I've created a script to do two database updates:
Firstly, all records are deleted from the database where the memberGUID, pageId and itemId fields match (i.e. they've already added this item).
Secondly, the record is then recreated.
It all works brilliantly, except when the GUID value is passed into the delete statement, then I just get a caught exception.
So this works:
[Code]....
But this doesn't:
[Code]....
The weird thing is that because the GUID value is being saved in the second database call, it is definitely there and is definitely the right data type etc. Even if I hard-code it into the delete procedure it still causes the whole thing to fail.
why it's failing when I add the GUID parameter in the deletion process?
