Question

I am using Sql Server 2005 and Vb Studios 2010 on a .net Framework of 4.0. I am trying to get the exact number of rows from a database and populate a datatable then have a label show the number of rows.

Dim comm2 = db.selectcommand(db.conn, "*", "Tablename", " columnname = '" & Session(sessionvariable) & "' AND columnname = 'Unread '")
    Dim sqlda2 As New SqlDataAdapter(comm2)
    Dim dt2 As New DataTable
    sqlda2.Fill(dt2)
    Dim recordcount As Integer = dt2.Rows.Count
    messagecountlbl.Text = recordcount

this will always return the value of 1 and I know for a fact that I have multiple values for the data I am trying to pull. I have atleast 50 and the label should be displaying that amount.

I have also tried the Select Count statement and it does the same thing.

Fix I have added this to the post since there is a 24 hr wait to answer question:
I have found a quick and simple fix that I will shorten later in a class file that I have written but this should help alot of people out.

Dim sqlresult As Object
    Dim constring As String = "Connection string goes here"
    Dim dbcon As SqlConnection = New SqlConnection(constring)
    Dim sql As New SqlCommand
    dbcon.Open()
    sql.Connection = dbcon
    sql.CommandText = "SELECT COUNT (*) FROM Tablename WHERE Columnname = 'Unread' AND columnname = '" & Session("sessionvariable") & "'"
    sqlresult = sql.ExecuteScalar
    messagecountlbl.Text = sqlresult

Dim sqlresult As Object
Dim constring As String = “Connection string goes here”
Dim dbcon As SqlConnection = New SqlConnection(constring)
Dim sql As New SqlCommand
dbcon.Open()
sql.Connection = dbcon
sql.CommandText = “SELECT COUNT (*) FROM Tablename WHERE Columnname = ‘Unread’ AND columnname = ‘” & Session(“sessionvariable”) & “‘”
sqlresult = sql.ExecuteScalar
messagecountlbl.Text = sqlresult
