I am trying to create a table using rails migrations. after creating
the table i want to move data from one table to newly created table.
everything seems to be working fine.. only issue is speed of moving
Abc.find(:all).each do |a|
xyz.new do |x|
xyz.id = a.id
i have over 200,000 rows in my table.. and it is very slow...
is there a better way to move data quickly?
