I have been pulling my hair out trying to get a solution to something,
assuming idiotically that in a transaction scenario I would not be able to
get the insert it back out. It seems to work, I am wondering how and if it
is reliable.
Give the scenario where I have 2 inserts I want to make, since
MySQL doesn't guarantee that there will be no gaps in sequence values.
Assigment of the id is always atomic because innodb uses an AUTO_INC
lock that lasts for the time of the insert, not the life of the
transaction.
lets say your highest order number is 10
transaction begins for client 1

I can't create innoDB tables in db MySQL to do

I try to modify the my.cnf file with the instructions
that I find in manuel.pdf but it don't work.
Can you help me please ?
Thanks.
Ps : i'm french. :-)
please let us know the SQL query you are trying, and a DESCRIBE TABLENAME so we can
see how your table(s) are laid out. also, please tell us what you actually changed
in your my.cnf file
by the way, before you can do transactions, you must set the AUTOCOMMIT variable to
0

And you read the manual, right?
Transaction support depends on the version of MySQL you are running, and
the table type

So telling them to RTFM doesn't help, because even if they do, it won't give
