Solution 1

You need to either join the tables in the query if there's a relationship between them or if the 'same' data is distributed between two tables you can use UNION.

For more information see

- UNION[^]

Also you can fetch multiple results sets if you like. Have a look at Executing multiple SQL statements as one against SQL Server[^]

Use SqlDataAdapter with DataSet. DataSet can contain multiple tables.

my issue is to read the two tables with sqlreader.
and need to display them in one gridview .
but at this situation i am able to display only one table with this query

"select *from Employee1 ; select *from Employee2";

i think i need to use NextResult() to overcome this.And thanku dude for the response

You can use that. Better to use DataAdapter for DataSets.

Solution 3

Combine Two Query in One otherwise use SqlAdapter with Dataset.

SqlConnection con = new SqlConnection(ConnectionString);

    String query = "select * from Employee1 , Employee2";

    SqlCommand cmd = new SqlCommand(query,con);

    SqlDataReader dr;

    con.Open();

    dr = cmd.ExecuteReader();

    GridView1.DataSource = dr;

    GridView1.DataBind();

    con.Close();

Hello,
Ya Its True if You use Both Query then Use NextResult() to Overcome Otherwise to Use Dataset.
