将列表绑定到 sqlalchemy 查询 python mysql

Question

如何将列表绑定到 SQL alchemy 查询？ 以下方法无效。

1. engine.execute("DELETE FROM testing WHERE test_id IN %s", [1,2,3])
2. engine.execute("DELETE FROM testing WHERE test_id IN %s", tuple([1,2,3]))
3. engine.execute("DELETE FROM testing WHERE test_id IN (%s)", [1,2,3])

他们都给我错误：not all arguments converted during string formatting

Answer 1

您可以通过将列表转换为元组来将列表绑定到查询：

engine.execute("DELETE FROM testing WHERE test_id in %(ids)s, ids=tuple([1,2,3])))
