title: Can doctrine Transaction also includes other queries run by codeigniter database library
body: <p>So Doctrine is very nice so the Code Igniter is .. both are well and different things, 
  I am using CI+Doctrine.. but sometimes CI's active record seems to be easy for simpler queries. but now what about transactions.. can i beginTransaction() from Doctrine Connection and then comit or roll back with some CI's database queries ..</p>
  
  <p>Can i do this ... means rollback will rollback every sql run by Doctrine as well as by CI ...</p>
  
  <p>Thanks in Advance ... </p>
