Dear all
I have a question about JDBC transactions
if we control the boundaries of a normal jdbc transactio, by setting autoCommit() to false and using commit or rollback to end the transaction, and if within the transaction we did a multiple updates , the updated values will not be reflected on the underlaying RDBMS 'till we commit , thats what JDBC specs saying, now
how comes there is something called "DIRTY READ", HOW COMES THAT ANOTHER TRANSACTION WILL READ A "PARTIAL" RESULT FROM ANOTHER ONE???
Thanks
