Question

• Is it possible to store a cache copy of the table data locally to avoid transfer (data does not change, This I assure it!) in SQL Server. So C++, C# can know the data stored by SQL in cache and then read the data in cache and compute some things with the table?

• Is it possible this kind of communication between SQL Server and C++ or C# via cache memory copy of table data?

  • If this is possible, What would be the steps?

Answer 1

ADO.You need to use ADO.NET (Disconnected) DataSets:

1) Create a Dataset

DataSet dsCustomers = new DataSet();

2) Create a DataAdapter, specifying what data to get

SqlDataAdapter daCustomers = new SqlDataAdapter(
    "select CustomerID, CompanyName from Customers", conn);

3) Fill the Dataset

daCustomers.Fill(dsCustomers, "Customers");

After which you can Query your Dataset.
