Question

In every ASP.NET application I have written, I would make number of request to the database before outputting the information onto the web page.

For example:

var DataTable1 = GetDataTable('Select * From Customers'); var DataTable2 = GetDataTable('Select * From Products'); var DataTable3 = GetDataTable('Select * From Orders'); 

As far as I’m aware, the code above would make 3 separate trips to the database and would do them one after the other.

Is there anyway I can gather together my parameterized SQL statements and make only 1 trip to the database server?

Answer 1

var SqlString = 'SELECT * FROM Customers; SELECT * FROM Products; SELECT * FROM ORDERS;'); var ds = GetDataSet(SqlString); var DataTable1 = ds.Tables(0); var DataTable2 = ds.Tables(1); var DataTable3 = ds.Tables(2);
