Question

I have written a single stored procedure that returns 2 tables:

select * 
from workers

select *
from orders

I call this stored procedure from my C# application and get a DataSet with two tables, and everything is working fine.

My question is how can I change the tables name at the SQL Server side so that in the C# side I will be able to access it via a name (instead of Tables[0]):

myDataSet.Tables["workers"]...

I tried to look for the answer in Google but couldn’t find it. Maybe the search keywords was not sufficient.

You cannot really do anything from the server-side to influence those table names – those names only exist on the client-side, in your ADO.NET code.

What you can do is on the client-side – add table mappings – something like:

SqlDataAdapter dap = new SqlDataAdapter(YourSqlCommandHere);
dap.TableMappings.Add("Table", "workers");
dap.TableMappings.Add("Table1", "orders");

This would “rename” the Table (first result set) to workers and Table1 (second result set) to orders before you actually fill the data. So after the call to

dap.Fill(myDataSet);

you would then have myDataSet.Tables["workers"] and myDataSet.Tables["orders"] available for you to use.
