So I have I think around 36,000 just to be safe, a number I wouldn't think was too large for a modern sql database like mysql. Each record has just two attributes.
So I do: so I collected them into one single insert statement
sql = "INSERT INTO tasks (attrib_a, attrib_b) VALUES (c1,d1),(c2,d2),(c3,d3)...(c36000,d36000);"
ActiveRecord::Base.connection.execute sql
from C:/Ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/connection_adapters/abstract_adapter.rb:219:in `log'
from C:/Ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/connection_adapters/mysql_adapter.rb:323:in `execute_without_analyzer

from C:/Ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/vendor/tzinfo-0.3.12/tzinfo/time_or_datetime.rb:242
I don't know if the above info is enough, please do ask for anything that I didn't provide here. So any idea what this is about?
THANK YOU!!!!
