Connecting to SQL Server 2008 database using asp
I tried a lot but I am not able to deal with this problem. I wasted last 2 days without any significant result. Hope I will get some help here.
I wanted to connect to a SQL Server 2008 database using ASP. I installed SQL Server 2008, created a database, but I am not able to connect to that database using the asp code. I can see the database in Visual Web Developer, I can also connect it through asp.net using the add connection wizard of visual web developer but I don't want to use add connection wizard. I want to write my asp code to connect to SQL Server database in notepad. My IIS is working and I am able to run asp code to access other开发者_Python百科 database like ms access database but I can't access SQL Server db.
The object explorer of SQL Server Management Studio shows:
localhost\SQLSERVER3(SQL Server 10.0.1600-RAJ-PC\raj)
Databases
examples
tables
System Tables
dbo.cars
columns
id(PK,int,not null)
name(varchar(50),null)
You can see the SQL Server and its databases in the attached jpg image. I want to connect to example database and then want to access cars table.
Please help me.
UPDATED
here is my code :
<html>
<head>
<title>Guestbook</title>
</head>
<body bgcolor="white" text="black">
<%
'Dimension variables
Dim adoCon 'Holds the Database Connection Object
Dim rsGuestbook 'Holds the recordset for the records in the database
Dim strSQL 'Holds the SQL query for the database
'Create an ADO connection odject
Set adoCon = Server.CreateObject("ADODB.Connection")
'Set an active connection to the Connection object using a DSN-less connection
adoCon.Open "ODBC;Driver={SQL Native Client};" & _
"Server=localhost\SQLSERVER3;" & _
"Database=examples;" & _
"Uid=raj;" & _
"Pwd=love1987"
'Set an active connection to the Connection object using DSN connection
'adoCon.Open "DSN=guestbook"
'Create an ADO recordset object
Set rsGuestbook = Server.CreateObject("ADODB.Recordset")
'Initialise the strSQL variable with an SQL statement to query the database
strSQL = "SELECT name FROM dbo.cars;"
'Open the recordset with the SQL query
rsGuestbook.Open strSQL, adoCon
'Loop through the recordset
Do While not rsGuestbook.EOF
'Write the HTML to display the current record in the recordset
Response.Write ("<br>")
Response.Write (rsGuestbook("Name"))
'Response.Write ("<br>")
'Response.Write (rsGuestbook("Comments"))
'Response.Write ("<br>")
'Move to the next record in the recordset
rsGuestbook.MoveNext
Loop
'Reset server objects
rsGuestbook.Close
Set rsGuestbook = Nothing
Set adoCon = Nothing
%>
</body>
</html>
I am able to connect using the following connection string on my local dev machine (with SQL 2008 R2 Express):
Driver={SQL Server}; Server=hostname\instancename; Database=dbname; Uid=user; Pwd=password
One thing I noticed in your code: you are trying to establish a DSN-less connection, then you run a query on it without USE dbname or anything. That may be the issue, or a least an issue.
Try creating a DSN, and then refer to it by name in your connection string.
- Open the ODBC icon in your Control Panel.
- Choose the System DSN tab.
- Click on Add in the System DSN tab.
- Select the Microsoft Access Driver. Click Finish.
- In the next screen, click Select to locate the database.
- Give the database a Data Source Name (DSN).
Click OK.
set conn=Server.CreateObject("ADODB.Connection")conn.Open "northwind"
