I have a table like below
Process_1
Tab1_Count
Tab1_Process_Count
Tab1_Status
Process_2
Tab2_Count
Tab2_Process_Count
Tab2_Status
Tab1_Process
123
123
Equal
Tab2_Process
123
126
Not Equal
I am trying to Unpivot the above like the below
TABLEPROCESS
Tab_Count
Process_Count
Status
Tab1_Process
123
123
Equal
Tab2_Process
123
123
Not Equal
With the below query
SELECT *

but it is giving me error -- ORA-00907: missing right parenthesis
As per comment by Alex Poole tried CROSS APPLY method

It is working in SQL Server but it is giving ORA-00903: invalid table name in oracle

I am trying to get all the customers whether they have install service or not from TRANS_TABLE.
NOA- query to get only the MAX product and join again with TRANS_TABLE by email id to get the all the MAX customers details (wwhther they have install service by adding Y OR N, but this query return duplicate with REP Product as well
Below is my Oracel Query which give duplicated
with CTE as (SELECT NOA.*,
CASE
WHEN TRANS_TABLE.product_name LIKE '%Installation%' THEN 'Y'
ELSE 'N'
END AS Installaion ,
ROW_NUMBER() OVER (PARTITION BY TRANS_TABLE.email_address ORDER BY TRANS_TABLE.email_address) AS rn
FROM (SELECT DISTINCT email_address
FROM TRANS_TABLE
WHERE email_address IS NOT NULL
and pdct_name like '%MAX%'
) NOA
LEFT JOIN TRANS_TABLE
ON NOA.email_address = TRANS_TABLE.email_address
select * from cte where rn='1'
The following code will help:
CTE AS (
SELECT
NOA.*,
CASE
WHEN TRANS_TABLE.PDCT_NAME LIKE '%INSTALLATION%' THEN 'Y' -- case sensitive name is used
ELSE 'N'
END AS INSTALLAION,
ROW_NUMBER() OVER(
PARTITION BY TRANS_TABLE.EMAIL_ADDRESS
ORDER BY
TRANS_TABLE.EMAIL_ADDRESS
) AS RN
FROM
(
SELECT DISTINCT
PDCT_NAME,
EMAIL_ADDRESS
FROM
TRANS_TABLE
WHERE
EMAIL_ADDRESS IS NOT NULL
AND PDCT_NAME LIKE '%MAX%'
) NOA
LEFT JOIN TRANS_TABLE ON NOA.EMAIL_ADDRESS = TRANS_TABLE.EMAIL_ADDRESS
WHERE TRANS_TABLE.PDCT_NAME NOT LIKE '%REP%') -- added this WHERE condition
SELECT
PDCT_NAME, EMAIL_ADDRESS, INSTALLAION
FROM
CTE
WHERE
RN = '1'

Here's an article about what you can achieve in Oracle 12c with the OFFEST FETCH based on Kaushik Nayak.

I hope it can help you to convert your original query to 11g. Good luck.
I have a query insert statement like shown below
insert into my_table
select col1,col2,CASE
WHEN EXISTS
(SELECT 1 FROM Table_A m WHERE m.COLA='XXX' AND m.id=b.id
)
THEN
(SELECT m.COLB FROM Table_A m WHERE m.COLA='XXX' AND m.id=b.id
)
ELSE 'Not Open'
END XXX,
CASE
WHEN EXISTS
(SELECT 1 FROM Table_A m WHERE m.COLA='YYY' AND m.id=b.id
)
THEN
(SELECT m.COLB FROM Table_A m WHERE m.COLA='YYY' AND m.id=b.id
)
ELSE 'Not Open'
END YYY,
.
.
.
.
. -- ~150 case statement
from Test b,table_main c
where b.id=c.id
Here we have case statement which is referring same table (TABLE_A) but checking for different values(XXX,YYY,etc..,) in each statement. This is taking so much time. We are trying to optimize this insert query. Could someone help here?
Try a variation of a pivot query:
SELECT col1, col2 ,
coalesce ( max( CASE WHEN m.COLA='XXX' THEN m.COLB END ), 'Not open' ) As XXX,
coalesce ( max( CASE WHEN m.COLA='YYY' THEN m.COLB END ), 'Not open' ) As YYY,
.....
.....
coalesce ( max( CASE WHEN m.COLA='ZZZ' THEN m.COLB END ), 'Not open' ) As ZZZ
FROM Test b
JOIN table_main c ON b.id=c.id
LEFT JOIN Table_A m ON m.id=b.id
GROUP BY col1, col2
Rewrite using decode and LEFT JOIN as follows.
SELECT col1, col2 ,
decode ( m.COLA , 'XXX' , m.COLB , 'Not Open' ) XXX ,
decode ( m.COLA , 'YYY', m.COLB , 'Not Open' ) YYY ,
...
...
FROM Test b LEFT JOIN Table_A m ON m.id=b.id JOIN table_main c
ON b.id=c.id;
It is taking time because you are making several calls to a table to get your values. Simply reduce the number of calls being made to Table_A.
If the condition Table_A.id = m.id and m.COLA= 'Any Value' will always return one row then you can join the tables Table_A, Test and Table_main in a single join like below
Insert into my_table(col1, col2) values
select
decode(a.COLA,'XXX' , a.COLB , 'Not Open'),
decode(a.COLA,'YYY' , a.COLB , 'Not Open'),
...
...
from Table_A a, Test b, Table_main c
where a.id = b.id
and b.id = c.id
In case the condition may return multiple records then you can use With clause like below
Insert into my_table(col1, col2) values
with table_a as (select col1, col2 , a.COLA, a.COLB
from Table_A a, Test b, Table_main c
where a.id = b.id
and b.id = c.id
group by col1, col2,a.COLA, a.COLB)
select col1,col2,
decode(x.COLA,'XXX' , x.COLB , 'Not Open'),
decode(x.COLA,'YYY' , x.COLB , 'Not Open'),
....
....
from table_a x
WE have :-
TABLE_1 having column (A_COL,NUM ) and TABLE_2 having column ( B_COL ,C_COL , NUM)
Q condition
If A_COL is NULL in the TABLE_1 then, populate the C_COL into B_COL column from TABLE_2
TRIED :-
Select
CASE WHEN A_COL IS NULL THEN B_COL = C_COL end as ABC_COL
from line
FROM TABLE_2 A
LEFT OUTER JOIN
TABLE_1 B
ON
A.NUM = B.NUM
I tried this but B_COL = C_COL not able to populate column C_COL into B_COL ,Do we have any other way to do this?
Try the below :
tab_1 as A and tab_2 as B
Selecting complete table 2 with condition :
Select
B.colB,
if ( A.colA = null , B.colB , B.colC) as B.colC,
B.num
from Tab_2 B
LEFT OUTER JOIN
TABLE_1 A
ON
A.NUM = B.NUM
Let me know if it dint work out.
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
I think below code will help,
ALTER FUNCTION [dbo].[Subtopics_getsum]

LEFT OUTER JOIN accounting.documentdetail

WHERE ( parentid = T1.topicid )))
SELECT Isnull(Sum(debit), 0) AS Debit,
Isnull(Sum(credit), 0)AS Credit
FROM cte AS c
WHERE ( newparentid = #TopicID )
)
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
ON T1.TopicID = c.NewParentID
In the code above your T1.Debit refers to Accounting.Topics.
