Solution 1

You can use Inner join in SQL to fetch result and then fill dataset.
your Query may be like this

SQL

Select table1.name, table1.ReorderQuantity, table2.Quantity, table2.BadQuantity
from table1, table2 where table1.id = table2.id

above Query will returns 4 columns, fill dataset using above result with the help of dataadapter.

C#

string query_login = "select * from Login";
SqlConnection con = new SqlConnection(conn);
SqlDataAdapter da_login = new SqlDataAdapter(query_login, con);
DataSet ds_login = new DataSet();
da_login.Fill(ds_login);

string query_user = "select * from user";
SqlDataAdapter da_user = new SqlDataAdapter(query_user, con);
DataSet ds_user = new DataSet();
da_user.Fill(ds_user);

ds_login.Merge(ds_user);
