back again, sorry.
i specified a model with a few one-to-many and one many-to-many
relations using SA 0.51 in MySql 5.1.25 rc; tables are all INNODB. all
works well and as expected in the ORM realm. however, when i'm trying
to use SQL Expression for a delete (row) operation, i get the dreaded
IntegrityError: (IntegrityError) (1451, 'Cannot delete or update a
parent row: a foreign key constraint fails
specifically, i'm using:
engine = create_engine('mysql://root:@localhost:3306/test2')
connection = engine.connect()
metadata = MetaData(bind=engine)
main_table = Table('main_table', metadata, autoload=True)
target_id = 1 #for illustrative purposes, primary key to delete
connection.execute(main_table.delete().where(main_table.c.id
==target_id))
where main_table is my main table and all other tables link to its id
(primary key int) via
foreign keys.
thx for you help
