Are you sure it doesn't do it out of the box?
I know it does for ZPsycopgDA which is the Postgresq Zope database adapter.
With that one I don't have to come near handling the SQL transactions.
What Zope commits and rollsback is done for SQL too automatically.

Hi there,
I am implementing a tool to handle userdata that is stored in a MySQL db.
The underlaying logic of the stored procedures used to maintain the db
content
dictate that I have to control the transactions myself.
I understand that there is a way to handle transaction controll in the
ZMySQL
methods. However I find no documentation at all on how to use it.
Without using ZMySQL methods I would be using the following piece of code:
db = mysql.connect(host="localhost" ...)
cursor = db.cursor()
query = "CALL insertUser('%s', '$xxx$', @id, @error);select @id, @error"
% 'JohnTheUser'
cursor.execute(query)
# get the next resultset, it has the result of the select
cursor.nextset()
result = cursor.fetchall()[0]
error = int(result[1])
if error:
print "error %s when trying to add user %s" % (ERRRORS[error],
'JohnTheUser')
db.rollback()
continue #we are in a loop actually
..
db.commit()
How can I mimic that using ZSQL Methods
thanks for any pointers
Robert
