How can I do a sql query in vb.net that can do that...

- Check if the user exists... then check if is admin:
-- If this statement is true, then print User FullName in lblFullName and YOU IS ADMIN in lblLevelAccess
Else

Dim SQL As String<br />
SQL = "SELECT U.CodUser, U.FullName FROM tblUser U INNER JOIN tblAccess A ON U.CodUser = A.CodUser WHERE A.AccessLevel = 'Admin' AND A.CodUser = @CodUser"<br />
Dim myCommand = New SqlCommand(SQL, myConnection)<br />
myCommand.Parameters.Add("@CodUser", SqlDbType.VarChar).Value = CardNum<br />
<br />
Dim reader As SqlDataReader = myCommand.ExecuteReader()<br />
Dim reader2 As SqlDataReader = myCommand2.ExecuteReader()<br />
'Caso existam linhas<br />
If reader.HasRows Then<br />
While reader.Read()<br />
lblFullName.Text = reader(1)<br />
lblLevel.Text = "Admin"<br />
txtCardNum.Text = ""<br />
End While<br />
reader.Close()<br />
<br />
...<br />

Else<br />
lblNomeCliente.Text = reader(1)<br />
lblLevel.Text = "Normal User"<br />
txtCardNum.Text = ""<br />
reader.Close()<br />
