I am not able to use the with clause in oracle adodb connection. I have tried both wrapping the qry is a select * from (myquery) and adding a , before my with clause. All create errors.
Here is the query
`WITH TEMPa AS (select _nbr, sum(ending) as Cost from t1 group by _nbr),
TEMPB AS (select _nbr, cost,entity
from t2
where end_tms is null and sale_date is null and entity = 110)
SELECT
TEMPA._nbr
,TEMPA.cost
,TEMPb._nbr
,TEMPB._cost
,tempb.entity
,(tempb._cost - tempa.cost) as Difference
FROM TEMPA, TEMPB
WHERE TEMPA._nbr = TEMPB._nbr(+)
and tempa.cost <> tempb.cost`
Any help would be awesome!

While trying to run SQL query for PostgreSQL, instead of the column names from the table referred it it pushing down * to the database.

As you can see, Jdbc Scan for table1 was using column names.
but, Jdbc Scan for table2 and table3 was not using column names. It pushed down * to the database.
How can I control jdbc scan so that it can push down colume names?
Apache Drill version is 1.16.0 (embedded-mode)
I tried to reproduce it with MySQL on both Drill 1.17 and Drill 1.15, but for the query, similar to the query you have specified, all the query is pushed into the JDBC storage:
SELECT m.person_id,
cnt_c_no
FROM
(SELECT person_id
FROM mysql.`drill_mysql_test1`.person1
WHERE date_field >= '2019-01-01 00:00:00') AS m
LEFT JOIN
(SELECT ci.person_id,
count(ci.last_name) AS cnt_c_no
FROM
(SELECT person_id,
last_name
FROM mysql.`drill_mysql_test`.person) AS ci
INNER JOIN
(SELECT last_name
FROM mysql.`drill_mysql_test`.person2
WHERE boolean_field = 'F' ) AS c ON ci.last_name = c.last_name
GROUP BY ci.person_id) AS join1 ON m.person_id = join1.person_id
The plan for this query:
00-00 Screen
00-01 Project(person_id=[$0], cnt_c_no=[$1])
00-02 Jdbc(sql=[SELECT `t0`.`person_id`, `t5`.`cnt_c_no` FROM (SELECT `person_id` FROM `drill_mysql_test1`.`person1` WHERE `date_field` >= '2019-01-01 00:00:00') AS `t0` LEFT JOIN (SELECT `t1`.`person_id`, COUNT(`t1`.`last_name`) AS `cnt_c_no` FROM (SELECT `person_id`, `last_name` FROM `drill_mysql_test`.`person`) AS `t1` INNER JOIN (SELECT `last_name` FROM `drill_mysql_test`.`person2` WHERE `boolean_field` = 'F') AS `t3` ON `t1`.`last_name` = `t3`.`last_name` GROUP BY `t1`.`person_id`) AS `t5` ON `t0`.`person_id` = `t5`.`person_id` ])
Could you please provide CTAS for Postgres tables, so I will try to reproduce it again with specific data types. Also, if possible, please check whether this issue is still reproduced on Drill 1.17.
UPD:
Comment under this answer helped to discover that this problem was caused by the following issue: https://issues.apache.org/jira/browse/DRILL-7340 and it will be resolved in Drill 1.18.0.
Why can't I use a subquery factoring clause result in the where clause of as depicted in the following sql:
with rpt as(
select * from reports where caseid =
:case_id and rownum=1 order by created desc
)
select
distinct rt.trialid
from
report_trials rt
join
trial_genes tg on rt.id=tg.trialid
where
rt.reportid = rpt.id
and
tg.gene not in('TMB','MS')
The subquery is named rptand used in the select statement's where clause. When executed encountering the following error: ORA-00904: "RPT"."ID": invalid identifier
UPDATE:
In fact nested query for the same thing is also giving me the same issue. The nested subquery is only returning a single column value from a single row:
select
distinct rt.trialid
from
report_trials rt
join
trial_genes tg on rt.id=tg.trialid
where
rt.reportid = (select id from reports where caseid = :case_id and
rownum=1 order by created desc)
and
tg.gene not in('TMB','MS')
You missed to add the table rpt in your query, thus that error.
with rpt as(
select * from reports where caseid =
:case_id and rownum=1 order by created desc
)
select
distinct rt.trialid
from
report_trials rt
join
trial_genes tg on rt.id=tg.trialid
join
rpt on rt.reportid = rpt.id
where
tg.gene not in('TMB','MS')
I am converting Oracle SQL into Laravel. The problem is how can make the code below in Eloquent way. I am more proficient in raw SQL though.
SELECT idx, ntiIdx, readCnt
FROM (SELECT a.idx, a.ntiIdx, a.readCnt
FROM EH_APPLICANT a
INNER JOIN EH_ITEM I ON a.netIdx = i.idx AND a.userIdx = ?
ORDER BY testDate DESC, testTime DESC
)
WHERE ROWNUM = 1
I'm trying to frame the below query but it always gives me the error "SQL command not properly ended". How do i use it??
INSERT INTO PROGRAM_KPI (AMSPROGRAMID,MASTER_KPI_ID,LASTUPDATEDBYDATALOAD)
(SELECT 'PRG-026',MASTER_KPI_ID,to_char(sysdate,'dd-mon-yy hh.mi.ss') from kpi_master)
WHERE NOT EXISTS(select * from insight_master
where amsprogramid = V_PROGRAMID
and inamsscope = 1
and tickettype = 'INCIDENT'
and TICKETSUBMITDATE is not null);
Please try this..(Removing the brackets and formating the code)
INSERT INTO program_kpi
(amsprogramid, master_kpi_id, lastupdatedbydataload)
SELECT 'PRG-026', master_kpi_id, TO_CHAR (SYSDATE, 'dd-mon-yy hh.mi.ss')
FROM kpi_master
WHERE NOT EXISTS (
SELECT *
FROM insight_master
WHERE amsprogramid = v_programid AND inamsscope = 1
AND tickettype = 'INCIDENT'
AND ticketsubmitdate IS NOT NULL);
But What is the relation between table program_kpi and insight_master ?
There seems to be no join between the inner and outer subquery.
select col_1,
col_2
from tbl_a A,
tbl_b B,
( select col_1,col_2 from tbl_c where clo_c_1 <> '1' ) C
where A.col_1 = B.col_1
and A.col_2 = B.col_2
and (A.col_2 = B.col_2
or C.col_2 = A.col_2);
My environment is Oracle,when I run this SQL,if the sub SQL C hasn't got a result,then the entire SQL returns NULL.Whereas if C has a result(not null) which fits other condions,there could be a result.Would somebody explain why sub SQL at the from area need to be not NULL?Thanks very much.
You need to bring yourself into the 90s and start using standard joins:
select col_1,
col_2
from tbl_a A
inner join
tbl_b B
on A.col_1 = B.col_1
and A.col_2 = B.col_2
left join
( select col_1,col_2 from tbl_c where clo_c_1 <> '1' ) C
on
C.col_2 = A.col_2
As a guess. I'm not entirely sure what your join conditions should be but that's my first attempt.
This is expected behaviour. When you join two result sets, you only want to get results where the join criteria is satisfied. If the criteria are not satisfied, you should get no results.
If I run the query "get me all the employees older than 65, and get their departments", if there are no employees older than 65, you would not expect to get any results, even if there are some departments in the database.
SELECT emp.name, dept.dept_name
FROM emp
JOIN dept
ON (emp.dept_no = dept.dept_no)
WHERE emp.age > 65;
As the others said, if you actually want to get rows regardless of whether the subquery has any results, you need to use an outer join.
