connect to Access database in asp.net and Join statement - asp.net

Question

Let say there is an Asp.ne5 3.5 web application with an Access database. The database has two tables like this:
In some pages I can get the username with `"page.users.identity.name". In this Application, each user can create so many pages. My question is how to write a statement to get pages created with specific username (the Group_ID in joined).
NOTE: This is what i tried and i got "error reading database".
SELECT Pages.* FROM
Pages INNER JOIN Users ON Pages.Group_ID = Users.Group_ID
WHERE Users.Username = page.users.identity.name

Answer 1

Have you tried using a parametrized query:
public ActionResult SomeAction()
{
// get the username of the currently connected user
string username = User.Identity.Name;
string cs = WebConfigurationManager.ConnectionStrings["MyConnStr"].ConnectionString;
using (var conn = new OleDbConnection(cs))
using (var cmd = conn.CreateCommand())
{
conn.Open();
var sql =
#"SELECT Pages.* FROM Pages
INNER JOIN Users
ON Pages.Group_ID = Users.Group_ID
WHERE Users.Username = ?";
cmd.CommandText = sql;
cmd.Parameters.AddWithValue("Username", username);
using (var reader = cmd.ExecuteReader())
{
while (reader.Read())
{
...
}
}
}
...
}

Try with this query,
SELECT Pages.* FROM
Pages,Users where Pages.Group_ID = Users.Group_ID
and Users.Username = page.users.identity.name

Answer 3

I Missed the Single quote "' " in the statement for page.users.identity.name. now this should be like this:
dim lasts as string= "'"
"SELECT Pages.* FROM
Pages INNER JOIN Users ON Pages.Group_ID = Users.Group_ID
WHERE Users.Username ='" & page.users.identity.name & lasts
