mysqldbhelper 1.0.2

A simple wrapper over mysqldb

For use with the mysqldb module for python

Usage

import mysqldbhelper
db = mysqldbhelper.DatabaseConnection('hostname',
                    user='username',
                    passwd='password',
                    db='databasename')

For single transactions

db.get_one('select book_name from book where isbn = %s', ('SOMEISBN',))

‘limit 1’ is automatically added

db.get_all('select book_name from book where author = %s', ('Richard Dawkins',))

db.put('''
insert into book
(book_name, book_author)
values
(%s, %s)''', ('Phantoms in the brain', 'V.S. Ramachandran')

put can be used for insert, update and delete queries

db.put('''delete from book
where
book_author = %s''' ('Deepak Chopra',))

For multiple transcations that need to be run atomically

try:
    db.start()
    db.get(...)
    db.put(...)
    ...
    db.save()
except Exception, e:
    db.rollback()
    raise
