I'm trying to implement the common "insert if not exists" pattern using sqlalchemy, but after a day of googling can't find out how to do it:
My query is like (sqlite backend): INSERT INTO memos(id,text) SELECT 5, 'text to insert' WHERE NOT EXISTS(SELECT 1 FROM memos WHERE id = 5 AND text = 'text to insert'); I know how to create the subquery, but just can't figure out how to pass the result of the subquery to insert, especially this subquery returns 2 fields. Can anyone please help? -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
