I have two queries with a union as follows:
select '00/00/0000' as payment_date , h1.customer_no
from payments h1
where not exists ( select 1 from payments h2 where h2.customer_no = h1.customer_no and h2.ctype = 'CASH' )
and h1.customer_no = 400
group by h1.customer_no
union
select to_char(h1.payment_date, 'MM/DD/YYYY') , h1.customer_no
from payments h1 inner join ( select customer_no, max(payment_date ) as max_date from payments where ctype = 'CASH' group by customer_no ) subQ
on ( h1.customer_no = subQ.customer_no
and h1.payment_date = subQ.max_date )
and h1.customer_no = 400
group by h1.payment_date, h1.customer_no
Now, I want to use this union in another query.
select * from (
select '00/00/0000' as payment_date , h1.customer_no
from payments h1
where not exists ( select 1 from payments h2 where h2.customer_no = h1.customer_no and h2.ctype = 'CASH' )
and h1.customer_no = p.customer_no
group by h1.customer_no
union
select to_char(h1.payment_date, 'MM/DD/YYYY') , h1.customer_no
from payments h1 inner join ( select customer_no, max(payment_date ) as max_date from payments where ctype = 'CASH' group by customer_no ) subQ
on ( h1.customer_no = subQ.customer_no
and h1.payment_date = subQ.max_date )
and h1.customer_no = p.customer_no
group by h1.payment_date, h1.customer_no ) sq,
payments p
where p.customer_no = 400
and sq.customer_no = p.customer_no
when I run this, I get ORA-00904: "P"."CUSTOMER_NO": invalid identifier. I need to join h1.customer_no to outer queries customer_no.
I have seen some queries with rank but I couldn't quite figure it out. How do I join the inner query with the outer query?
thanks in advance.
Does your payments table have a customer_no column? That seems to be what your error is indicating.
As for how to join the subqueries, you might want to look into factored subqueries. You can do:
WITH z AS (
SELECT ...
UNION
SELECT ...
), y AS (
SELECT ...
)
SELECT ...
FROM y
JOIN z ON y.x = z.x
JOIN some_other_table t ON z.a = t.a

How would the following START WITH / CONNECT BY hierarchical query look like when translated into a RECURSIVE SUBQUERY FACTORING hierarchical query with WITH clause:
SELECT t1.id
FROM table1 t1, table2 t2
WHERE t1.version_id = t2.id
AND t1.baseline_date = TRIM (TO_DATE ('2015-05-26', 'yyyy-mm-dd'))
AND t2.entry_date = t1.baseline_date
START WITH t1.id IN (SELECT id
FROM table1
WHERE parent_id = 101015)
CONNECT BY PRIOR t1.id = t1.parent_id
ORDER SIBLINGS BY t1.child_index;
I think you want:
WITH rsqfc (id, child_index, baseline_date) AS (
SELECT t1.id,
t1.child_index,
t1.baseline_date
FROM table1 t1
INNER JOIN table2 t2
ON ( t1.version_id = t2.id
AND t2.entry_date = t1.baseline_date )
WHERE t1.parent_id = 101015
UNION ALL
SELECT t1.id,
t1.child_index,
t1.baseline_date
FROM rsqfc r
INNER JOIN table1 t1
ON (r.id = t1.parent_id)
INNER JOIN table2 t2
ON ( t1.version_id = t2.id
AND t2.entry_date = t1.baseline_date )
)
SEARCH DEPTH FIRST BY child_index SET order_id
SELECT id
FROM rsqfc
WHERE baseline_date = DATE '2015-05-26';
However, without sample data it is difficult to be sure.

I have something similar to the code below. I'm new to Oracle. It works fine until I try to join it to "anothertable" then states it can't see cte2.a. I can't find anything that explains why it can't see cte2.a
I need the data created by cte2 to further my query. Should i just do that inside of cte2 instead?
WITH cte 1 as (......),
cte2 as (....join tablename on tablename.x = cte1.x)
select *
from cte2
join anothertable on anothertable.a = cte2.a

I tried the below and its working for me. Just check is it something like this you are expecting?
WITH cte AS
( select 'a' as a from dual
union
select 'g' as a from dual
), cte2 AS
(select 'a' as b from dual
union
select 'c' as b from dual
)
SELECT *
FROM cte c inner JOIN cte2 c2 ON c.a = c2.b
Your query works:
WITH cte1 (x) as (
SELECT dummy FROM DUAL
),
cte2 (x, a) as (
SELECT tablename.x,
tablename.a
FROM cte1
join tablename
on tablename.x = cte1.x
)
select *
from cte2
join anothertable
on anothertable.a = cte2.a;
Which, for the sample data:
CREATE TABLE tablename ( x, a ) AS
SELECT dummy, ROWNUM FROM DUAL;
CREATE TABLE anothertable ( a ) AS
SELECT ROWNUM FROM DUAL;
Outputs:
X | A | A
:- | -: | -:
X | 1 | 1

As far as i know, I can not add index from view at oracle, so I am guessing the culprit is this sub query at TMI_ISD_WV_LINK_REV4:
(
select system_matter_id from (select system_matter_id from TMI_ISD_ALL_WORKFLOW wfl WHERE wfl.DATA_NO IN (wvl.R_DATA_NO,wvl.P_DATA_NO) order by wfl.create_date_TIME desc )
where rownum <= 1--fetch first 1 row only
)SYSTEM_MATTER_ID
Actually this performance has been tuned up using Materialized View, but the data will updated every 3 minutes once, or like that.
Thank You all.
I have done following CTE it works fine,but I need to get sum of the last node so the problem is when I add T1.Debit Column to be calculated its give me an invalid column name 'Debit' !!! on line ***

let me know whats wrong with my code confused !!!
actually it doesn't return me a last node sum of debit,credit ... !!!
check following pic

SELECT Isnull(Sum(debit), 0) AS Debit,
Isnull(Sum(credit), 0)AS Credit

I think you Accounting.Topics hasn't column Debit.
UPDTAE
isnull((T1.Debit),0)+isnull(c.Debit,0) AS Debit,--IN THIS LINE error 'Invalid Column Name 'Debit''
isnull(c.Credit,0) AS Credit
FROM cte AS c
INNER JOIN Accounting.Topics AS T1

In the code above your T1.Debit refers to Accounting.Topics.

Note that this query will work if you have 1 record == 1 day! If you have multiple records in a day, the results will be different from the other query.
As I said here, if you want really fast calculation, put it into temporary table with sequential primary key and then calculate rolling total:
create table #Temp (

NetWin decimal(29, 10)
)
insert into #Temp ([Date], NetWin)
select

I assume that you could have duplicates dates in the input, but don't want duplicates in the output, so I grouped data before puting it into the table.
