问题
I would like to ask how to change the OUTER from Informix to HQL query. Currently facing error with unexpected token:outer
SQL query:
select a.SC_OB_PROFILE_CODE, b.SC_ORIG_SF_GROUP_CODE, f.SC_ORIG_SAC,
f.SC_ORIG_FAC,b.SC_PROD_CONT_GROUP_CODE, d.SC_PROD_CONT_CODE, e.GP_CD, a.SC_ORIG_COUNTRY,
a.SC_DEST_COUNTRY, a.SC_DEST_SAC, a.SC_DEST_FAC, a.SC_SEND_DOW,
a.SC_OB_SORT_CODE, a.ORIG_OB_SORT_CODE, a.TARGET_OB_SORT_CODE, a.SC_TIMESTAMP
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
HQL query:
@SuppressWarnings("unchecked")
public List<LoginCountryEBean> getExportDetails(String country){
List<LoginCountryEBean> expDel = null;

回答1:
The syntax to make a join is
select ... from Entity1 e1
[inner | left [outer]] join e1.entity2s e2
[inner | left [outer]] join e2.entity3s e3
...
Read the documentation
回答2:
The trouble you're running into is that the (obsolescent) old-style Informix OUTER join notation is not understood by other systems (such as HQL). Here's a slightly simplified version of the original Informix query:
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;
Primarily, I've simplified the select-list by using a.*
notation for selecting the columns from each aliased table name, and I've exposed the FROM clause contents a bit more clearly.
The tables (with aliases — but I'm going to pretend that the aliases are the table names) a
and b
are inner joined. That is outer joined to f
; it is also independently outer joined to the result of d
outer joined to e
. To rewrite this so that HQL has a chance of understanding it, we're going to have to write something close to this:
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;
Apart from inverting the case of keywords vs database objects, this is a fairly direct translation of the original query. You will note that the outer joined sub-query is given the alias ef
in this revision. This is necessary; the SQL standard mandates that such sub-queries are given an alias. You therefore may run into ambiguous column errors. You can probably fix those by by replacing the *
notation in the sub-query with the exact set of column names you want to select. And, of course, you'll need to replace the *
notation in the select-list with the set of columns that you want once more.
