ORA-01427 单行子查询 returns 多于一行

Question

我有这样的查询：

select bb10.ID_SEKTOR_10 as kode, 
bb10.NAME_SEKTOR_10 as sektor10,
(
    select count(*) as HUBBNI_SEKTOR_EKONOMI10 
    from bbcust_debitur_dev 
    where HUBBNI_SEKTOR_EKONOMI10 = bb10.ID_SEKTOR_10
    and STATUS = 2 
    group by HUBBNI_SEKTOR_EKONOMI10
) as total_sek_10,
(
    select  sum( distinct bbcd.baki_debet) as baki_debet
    from bbcust_cashloan_dev bbcd, bbcust_debitur_dev bdd
    where bbcd.row_id = bdd.row_id 
    and bdd.HUBBNI_SEKTOR_EKONOMI10 = bb10.ID_SEKTOR_10
    and bbcd.status =1 and bdd.status=2
    group by bdd.row_id
) as total_rek_10
from BBCUST_SEKTOR_10_DEV bb10;

我收到一个错误

ORA-01427 single-row subquery returns more than one row

但在我只有这样的数据之前，我没有任何错误。此查询没有任何错误。

select bb10.ID_SEKTOR_10 as kode, 
bb10.NAME_SEKTOR_10 as sektor10,
(
    select count(*) as HUBBNI_SEKTOR_EKONOMI10 
    from bbcust_debitur_dev 
    where HUBBNI_SEKTOR_EKONOMI10 = bb10.ID_SEKTOR_10
    and STATUS = 2 
    group by HUBBNI_SEKTOR_EKONOMI10
) as total_sek_10
from BBCUST_SEKTOR_10_DEV bb10;

结果是这样的：

bbcust_cash_loan的结构是这样的：

因为数据库的结构是：bbcust_debitur_dev 与 BBCUST_SEKTOR_10_DEV 和 bbcust_cashloan_dev 有关系。

我想计算 bbcust_cashloan_dev 中的每个值，但我需要知道 BBCUST_SEKTOR_10_DEV 中的所有数据。这就是为什么我加入所有数据，所以我从 bbcust_cashloan_dev 中获得总价值，其中数据在 BBCUST_SEKTOR_10_DEV.

你能告诉我如何解决我的查询吗？

Answer 1

试试这个......

select bb10.ID_SEKTOR_10 as kode, 
bb10.NAME_SEKTOR_10 as sektor10,
(
    select count(*) as HUBBNI_SEKTOR_EKONOMI10 
    from bbcust_debitur_dev 
    where HUBBNI_SEKTOR_EKONOMI10 = bb10.ID_SEKTOR_10
    and STATUS = 2 
    ) as total_sek_10,
(
    select  sum( distinct bbcd.baki_debet) as baki_debet
    from bbcust_cashloan_dev bbcd, bbcust_debitur_dev bdd
    where bbcd.row_id = bdd.row_id 
    and bdd.HUBBNI_SEKTOR_EKONOMI10 = bb10.ID_SEKTOR_10
    and bbcd.status =1 and bdd.status=2
    ) as total_rek_10
from BBCUST_SEKTOR_10_DEV bb10;

有可能 group by bdd.row_id returns 不止一行。不了解您的业务，无法提供建议。
