So I'm trying to retrieve the session variable (email) of the logged in user, and then use the variable in a SQL statement to retrieve the UserID of that user and place it in a read-only textbox. I can get the session variable and put that value in the textbox
but I also need the ID associated with the session(email).
After searching and trying 2 separate forum posts and analysing the breakpoints they both work to an extent but then I get the same error on both (System.Data.SqlClient.SqlException: 'The multi-part identifier "xxxxxx@gmail.com" could not be bound'. From
reading the error is mostly associated with problems joining tables but my blocks of code
don't do such a thing.
Here are the 2 separate blocks of code so if anyone could shed some light on why the error is appearing I would appreciate it hugely.
using (SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnString"].ConnectionString))
{
using (SqlCommand command = new SqlCommand("select UserID from Users where Email = " + Session["User"], connection))
{
connection.Open();
using (SqlDataReader reader = command.ExecuteReader())
{
while (reader.Read())
{
txtUserID.Text = reader[0].ToString();
}
}
}
}
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnString"].ConnectionString);
SqlCommand cmd = new SqlCommand("select UserID from Users where Email = " + Session["User"]);
SqlDataAdapter ap = new SqlDataAdapter(cmd.CommandText, conn);
DataSet ds = new DataSet();
conn.Open();
ap.Fill(ds);
txtUserID.Text = ds.Tables[0].Rows.Count.ToString();
conn.Close();

For anyone wondering the SQL statement should be like this,
Works for both variations
