Single Query returning me 4 tables, How to get all of them back into dataset?

How to fill multiple tables in a dataset.

I m using a query that returns me four tables.

At the frontend I am trying to fill all the four resultant table into开发者_Python百科 dataset.

Here is my Query. Query is not complete. But it is just a refrence for my Ques

Select * from tblxyz compute sum(col1)

suppose this query returns more than one table, I want to fill all the tables into my dataset

I am filling result like this

con.open();
adp.fill(dset);
con.close();

Now when i checks this dataset. It shows me that it has four tables but only first table data is being displayed into it. rest 3 dont even have schema also.

What i need to do to get desired output

Use DataAdapter.TableMappings. e.g. :

        DataSet ds = new DataSet();
        // setup DataSet if required

        SqlCommand cmd = new SqlCommand();
        // setup command

        SqlDataAdapter da = new SqlDataAdapter(cmd);

        da.TableMappings.Add("Table", "goofy");
        da.TableMappings.Add("Table1", "donald");
        da.TableMappings.Add("Table2", "daffy");
        da.TableMappings.Add("Table3", "foghorn");

        da.MissingSchemaAction =  MissingSchemaAction.AddWithKey;
        da.Fill(ds);

where "goofy" is the name of the DataTable you want your first result set to go into, and "donald" is the second etc.

Maybe the problem is that you need to return all your tables separetly, as different queries, for example, fill-ing the same DataSet in a loop.

Good Luck!
