Question

ServerA

Table1
Id  Name    State   Country
1   Abc OH  USA

Table2
Id  Counties    Places
1   abc     def
1   koi     koii
1   joi     joio

ServerB

Table1
Id  Name    State   Country

Table2
Id  Counties    Places

I have 2 servers ServerA and ServerB under both servers there are two tables Table1/Table2 i am trying to copy single rows from Table1 and associated rows from Table2 to ServerB’s Table1 and Table2.

This is how i tried doing it:

connection1 = connection to ServerA
connection2 = connection to ServerB

SqlCommand cmd1 = new SqlCommand("Select * from Table1 where id = 1");
SqlCommand cmd2 = new SqlCommand("Select * from Table2 where id = 1");

Connection1.Open();
Connection2.Open();

SqlDataReader reader1 = cmd1.ExecuteReader();
SqlDataReader reader2 = cmd2.ExecuteReader();

var value1 = reader1.read();
var value2 = reader2.read();

i use SqlDataReader and execute above commands and get the data and insert it into ServerB Table1 and Table2.
Is this correct way to do this? Can a better sql command be used?

Try Using SQLBULKCOPY (See Example here) which is much faster especially if you have huge data
