Ahmet,
What you are doing is not returning multiple tables. You are returning a
single table with the column att1. If you want to have multiple tables
returned, you need to use multiple select statements. Your best bet
would be to use a stored procedure in this case.
Stored Proc Example:
<code>
In SQL Server (or whatever RDBMS you are using):
CREATE PROCEDURE MultTableExample AS
SELECT col1, col2, col3 FROM Table1
SELECT col1, col2, col3 FROM Table2
GO
</code>
in C#:
<code>
SqlConnection connection = new SqlConnection("connection string");
DataTable table1 = new DataTable("Table1");
DataTable table2 = new DataTable("Table2");
DataSet multTables = new DataSet("MultTables");
SqlDataAdapter dataAdapter = new SqlDataAdapter("SELECT col1, col2, col3
FROM Table1",connection);
dataAdapter.Fill(table1);
dataAdapter.SelectCommand.CommandText = "SELECT col1, col2, col3 FROM
Table2";
dataAdapter.Fill(table2);
multTables.Tables.Add(table1);
multTables.Tables.Add(table2);
listbox.DataSource = multTables.Tables["Table2"];
listbox.DataTextField = "col1";
listbox.DataBind();
</code>
If you don't want to use stored procedures, then you can do it this way.
<code>
SqlConnection connection = new SqlConnection("connection string");
DataSet multTables = new DataSet("MultTables");
SqlDataAdapter dataAdapter = new SqlDataAdapter("MultTableExample
",connection);
dataAdapter.SelectCommand.CommadType = CommandType.StoredProcedure;
dataAdapter.Fill(multTables);
listbox.DataSource = multTables.Tables["Table2"];
listbox.DataTextField = "col1";
listbox.DataBind();
</code>

As you see, I want to put data coming as a result of joining of tables into
a dataset. Then I want to display the result of the join in a list box;
because the result will be one column.
Please help me, I am just a beginner
