Retrieving single piece of data from SQL database
Posted on 2006-11-14
I have this little snippet of code:
myconnectionstring = "Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ASPNETDB.MDF;Integrated Security=True;User Instance=True"
Dim myconn As New Data.SqlClient.SqlConnection(myconnectionstring)
Dim objcommand1 As New Data.SqlClient.SqlCommand("SELECT RTRIM(aspnet_ChamberWorkstation.Workstation) AS Expr1 FROM aspnet_ZoneChamber INNER JOIN aspnet_ChamberWorkstation ON aspnet_ZoneChamber.Zone = aspnet_ChamberWorkstation.Zone WHERE (aspnet_ZoneChamber.Chamber = '" & Me.DropDownList1.SelectedValue & "') AND aspnet_ChamberWorkstation.workstation = '" & objWSHNetwork.ComputerName & "'", myconn)
workstationcheck = objcommand1.ExecuteScalar
I'm trying to pull a single piece of data from the database which DOES exist. When the msgbox triggers, it is suppose to show the name of the workstation is pulls from the database, but in this case the box is just blank. I'm sure it's got something to so with my SQL statement but i can't figure out what i'm doing wrong.
Just as a heads up, objWSHNetwork.ComputerName, pulls the name of the workstation i am running on. I'm trying to do a verification with the database to make sure that the workstation I am currently on is listed as a secure workstation in the SQL database.
