SELECT REPLACE(REPLACE(@str, CHAR(13), ''), CHAR(10), '')

A good starting point

mylist = ['x', 3, 'b']
print '[%s]' % ', '.join(map(str, mylist))

Important Considerations:

• Setup pool class to sqlalchemy.pool.NullPool when you create database so we don't allow pooling and only one connection is created, and it is correctly deleted when we call close method.
• Connection needs to be closed at the end of each call. Close it in finally block.
