我想问一下如何将OUTER从Informix更改为HQL查询。目前因unexpected token:outer
select a.SC_OB_PROFILE_CODE, b.SC_ORIG_SF_GROUP_CODE, f.SC_ORIG_SAC,

from SC_OB_TEMP_AUDIT2 a, SC_OB_ALLOCATION b, outer SC_FAC_GROUP f,
outer (SC_OB_PROD_GROUP d, GBL_PRODUCT e)

进行连接的语法是
select ... from Entity1 e1
[inner | left [outer]] join e1.entity2s e2
[inner | left [outer]] join e2.entity3s e3
...
答案 1 :(得分:0)
您遇到的麻烦是其他系统(例如HQL)无法理解(过时的)旧式Informix OUTER连接符号。这是原始Informix查询的略微简化版本:
select a.*, b.*, d.*, e.*, f.*
from SC_OB_TEMP_AUDIT2 a,
SC_OB_ALLOCATION b,
outer SC_FAC_GROUP f,
outer (SC_OB_PROD_GROUP d, GBL_PRODUCT e)
where a.SC_ORIG_COUNTRY = 'MY'
and a.EXPORT_FLAG = 'N'
and a.SC_OB_PROFILE_CODE = b.SC_OB_PROFILE_CODE
and a.SC_ORIG_COUNTRY = b.SC_ORIG_COUNTRY
and f.SC_ORIG_COUNTRY = b.SC_ORIG_COUNTRY
and b.SC_ORIG_SF_GROUP_CODE = f.SC_FAC_GROUP_CODE
and d.SC_ORIG_COUNTRY = b.SC_ORIG_COUNTRY
and b.SC_PROD_CONT_GROUP_CODE = d.SC_PROD_GROUP_CODE
and e.GP_CNT_CD = d.SC_PROD_CONT_CODE
order by a.SC_TIMESTAMP, a.SC_OB_PROFILE_CODE, a.SC_DEST_COUNTRY;
首先,我通过使用a.*
表示法来简化选择列表,以便从每个别名表名中选择列,并且我已经更清楚地公开了FROM子句内容。
表(带别名 - 但我要假装别名是表名)a
和b
是内连接的。那是外部加入f
;它也独立地外部连接到d
外部加入e
的结果。为了重写这个以便HQL有机会理解它,我们将不得不写一些接近这个的东西:
SELECT a.*, b.*, d.*, ef.*
FROM sc_ob_temp_audit2 AS a
JOIN sc_ob_allocation AS b
ON a.sc_ob_profile_code = b.sc_ob_profile_code
AND a.sc_orig_country = b.sc_ob_orig_country
OUTER JOIN sc_fac_group AS f
ON b.sc_orig_country = f.sc_orig_country
AND b.sc_orig_sf_group_code = f.sc_fac_group_code
OUTER JOIN (SELECT e.*, f.*
FROM sc_ob_prod_group AS d
OUTER JOIN gbl_produce AS e
ON d.sc_prod_cont_code = e. gp_cnt_cd
) AS ef.*
ON b.sc_orig_country = ef.sc_orig_country
AND b.sc_prod_cont_group_code = ef.sc_prod_group_code
WHERE a.sc_orig_country = 'MY'
AND a.export_flag = 'N'
ORDER BY a.sc_timestamp, a.sc_ob_profile_code, a.sc_dest_country;
除了反转关键字与数据库对象的情况之外,这是对原始查询的相当直接的翻译。您将注意到外部联接子查询在此修订版中被赋予别名ef
。这是必要的; SQL标准要求为这些子查询提供别名。因此,您可能会遇到模糊的列错误。您可以通过将子查询中的*
表示法替换为您要选择的确切列名称来解决这些问题。当然,您需要将select-list中的*
表示法替换为您想要再次使用的列集。
