Hi, I’m having trouble with my grid view. When the user is signed into my site and clicks button1, the users name is turned into a string and used in a query to display all the information for that user, but unfortunately it doesn’t work. It should output all the CD’s the user has input into the database. Here’s the code I have… Code: Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Dim myString As String myString = Page.User.Identity.Name.ToString() Dim DBConn As New SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=""|DataDirectory|\aspnetdb.mdf"";Integrated Security=True;User Instance=True") Dim DBCmd As New SqlCommand Dim DBAdap As New SqlDataAdapter Dim DS As New DataSet Dim dt As New DataTable DBConn.Open() DBAdap = New SqlDataAdapter("SELECT * FROM Table1 WHERE UserName = " & myString, DBConn) DBAdap.Fill(dt) GridView1.DataSource = dt GridView1.DataBind() DBCmd.Dispose() DBAdap.Dispose() DBConn.Close() DBConn = Nothing End Sub When I run it this error comes up “SQLExeption was unhandled by usercode” and it also says “Invalid column name 'Rachel'.”. Rachel is actually the user I’m signed into the site and is the value in myString which is fine, but I don’t see what the problem is. Could it be that UserName is set to NVARCHAR in the sql database? Can someone help me out, I’d really like to get this working. Any advice or help would be great. Thanks, CaJack P.S. English isn’t my first language and I’m sorry if I haven’t explained my problem fully, if I haven’t explained it fully just let me know and I’ll try and explain it better. Thanks for reading.
I guess there's a problem with your SQL query, now your query looks like this Code: SELECT * FROM Table1 WHERE UserName = Rachel Where as it should look like this, Code: SELECT * FROM Table1 WHERE UserName = 'Rachel' Solution: Code: DBAdap = New SqlDataAdapter("SELECT * FROM Table1 WHERE UserName = '" & myString &"'", DBConn)
