原标题:SQLAlchemy: How do you delete multiple rows without querying

我的表格有数百万人。 我想通过一个条款删除多个条款。 然而,使用该守则:

session.query(Users).filter(Users.id.in_(subquery....)).delete()

上述法典将质疑结果,然后执行删除。 我不想这样做。 我希望速度。

我想能够执行(我知道这次会议)。 执行: ()

最佳回答

Yep! 您可在表格标的上打上delete(>,其中附有相关条款。

与此类似:

stmt = Users.__table__.delete().where(Users.id.in_(subquery...))

(然后不忘记执行声明:engine.execute(stmt))

问题回答

如果开发商不希望执行简单的香草,以下解决办法也会奏效。

session.query(Users).filter(Users.id.in_(subquery....)).delete(synchronize_session=False)
