小编use*_*591的帖子

有以下sql，最后一行出错， ERROR: sequence must have same owner as table it is linked to [Failed SQL: (0) ALTER SEQUENCE test_table_seq OWNED BY test_table.id

CREATE SEQUENCE test_table_seq;

ALTER TABLE test_table ALTER COLUMN id SET DEFAULT nextval('test_table_seq');
ALTER TABLE test_table ALTER COLUMN id SET NOT NULL;
ALTER SEQUENCE test_table_seq OWNED BY test_table.id;

任何建议如何避免该错误？谢谢！！！！

我有 2 节课A和B

class A

{
  int id,
  List<B>
}

class B

{
  int id
}

现在给出List<A>，我想过滤掉所有B.id> 3

前任。

List<A>：

{
  [
    id: 1,
    Bs: [1, 2, 3, 4, 5]
  ],
  [
    id: 2,
    Bs: [1, 2, 3, 4, 5]
  ]
}

预期结果是

{
  [
    id: 1,
    Bs: [1, 2, 3]
  ],
  [
    id: 2,
    Bs: [1, 2, 3]
  ]
}

怎么办stream, filter？谢谢！！！
