UNION on two select gives 'SQL Error: ORA-00907: missing right parenthesis'
提问by jai
I'm trying to UNION the results of two queries. But I'm getting the following error:
我正在尝试联合两个查询的结果。但我收到以下错误：
Error at Command Line:9 Column:81
Error report:
SQL Error: ORA-00907: missing right parenthesis
00907. 00000 - "missing right parenthesis"
Here's my query:
这是我的查询：
SELECT application_id, clicks, datee, client_id FROM(
(select
APPL_CD AS application_id,
count(*) as clicks,
to_date((to_char(ACTN_TAKE_DATA_TM, 'dd-mm-yyyy')), 'dd-mm-yyyy') as datee,
ALRT_RSPNS_FROM_CLIENT_ID AS client_id
from ALRT_PLATFORM_ALRT_HSTRY
where ACTN_TAKE_CD is not null
group by to_char(ACTN_TAKE_DATA_TM, 'dd-mm-yyyy'), APPL_CD, ALRT_RSPNS_FROM_CLIENT_ID order by datee)
UNION ALL
(select
APPL_CD AS application_id,
count(*) as clicks,
to_date((to_char(ACTN_TAKE_DATA_TM, 'dd-mm-yyyy')), 'dd-mm-yyyy') as datee,
ALRT_RSPNS_FROM_CLIENT_ID AS client_id
from ALRT_PLATFORM_ALRT
where ACTN_TAKE_CD is not null
group by to_char(ACTN_TAKE_DATA_TM, 'dd-mm-yyyy'), APPL_CD, ALRT_RSPNS_FROM_CLIENT_ID order by datee )
)

Remove the ORDER BYfrom the nested queries:
ORDER BY从嵌套查询中删除：
SELECT application_id, clicks, datee, client_id FROM(
(select
APPL_CD AS application_id,
count(*) as clicks,
to_date((to_char(ACTN_TAKE_DATA_TM, 'dd-mm-yyyy')), 'dd-mm-yyyy') as datee,
ALRT_RSPNS_FROM_CLIENT_ID AS client_id
from ALRT_PLATFORM_ALRT_HSTRY
where ACTN_TAKE_CD is not null
group by to_char(ACTN_TAKE_DATA_TM, 'dd-mm-yyyy'), APPL_CD, ALRT_RSPNS_FROM_CLIENT_ID)
UNION ALL
(select
APPL_CD AS application_id,
count(*) as clicks,
to_date((to_char(ACTN_TAKE_DATA_TM, 'dd-mm-yyyy')), 'dd-mm-yyyy') as datee,
ALRT_RSPNS_FROM_CLIENT_ID AS client_id
from ALRT_PLATFORM_ALRT
where ACTN_TAKE_CD is not null
group by to_char(ACTN_TAKE_DATA_TM, 'dd-mm-yyyy'), APPL_CD, ALRT_RSPNS_FROM_CLIENT_ID )
)
