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 --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
