Hi
I have the above table of data, I would like to group them into a single row ignoring NULL values, Any help on this greatly appreciated,
You can try this query, it will work
select max(classid),
classname,
max(frequency),
max(notice),
max(typeofdays),
max(rnotice),
max(classpercent)
from <table_name>
group by classname;
Using lag and partition can solve my requirement
SELECT FUND_CLASS_ID,
NVL(SUB_NOTICE_DAYS , LAG (SUB_NOTICE_DAYS , 1) OVER (PARTITION BY LFC.ID ORDER BY SUB_NOTICE_DAYS NULLS LAST)) SUB_NOTICE_DAYS ,
NVL(SUB_NOTICE_TYPE_OF_DAYS_ID , LAG (SUB_NOTICE_TYPE_OF_DAYS_ID , 1) OVER (PARTITION BY LFC.ID ORDER BY SUB_NOTICE_TYPE_OF_DAYS_ID NULLS LAST)) SUB_NOTICE_TYPE_OF_DAYS_ID
FROM CLASS

I'm trying to Right join two table on a column named "compte"
I need to do an addition after. The problem is that some "compte" doesn't exist in one of the table and as a result, the addition return null instead of keeping the based value
Here's the query
SELECT t.compte,t.posdev+x.mnt
FROM (
SELECT compte,SUM(mntdev) as mnt FROM mvtc22
WHERE compte IN ('11510198451','00610198451','40010198451','40010198453','00610198461','00101980081','00101980094',
'00101980111','40010198461','40010198462','40010198466','40010198463')
AND datoper BETWEEN '01/01/22' AND '06/01/22'
GROUP BY compte
)x
RIGHT OUTER JOIN
(
SELECT c.compte,c.posdev
FROM v_sldoper c
WHERE c.compte IN ('11510198451','00610198451','40010198451','40010198453','00610198461','00101980081','00101980094',
'00101980111','40010198461','40010198462','40010198466','40010198463')
AND datpos = '31/12/21'
)t
ON t.compte = x.compte
And the results :
I'm expecting to keep the results from the second subquery if there's no "compte" in the first subquery.
Thanks In advance,
Alex
You are very close, the problem is that in oracle SQL the result of any value + null value is null, so you need to handle potential null values from each column before applying the + operator betwen them.
To solve the issue, you can apply functions like NVL or decode or even CASE WHEN for that purpose.
Below I use NVL function to solve it (I assume t.posdev column cannot contain null values, otherwise apply nvl function to both columns).
SELECT t.compte, t.posdev + NVL(x.mnt, 0)
FROM (
SELECT compte,SUM(mntdev) as mnt FROM mvtc22
WHERE compte IN ('11510198451','00610198451','40010198451','40010198453','00610198461','00101980081','00101980094',
'00101980111','40010198461','40010198462','40010198466','40010198463')
AND datoper BETWEEN '01/01/22' AND '06/01/22'
GROUP BY compte
)x
RIGHT OUTER JOIN
(
SELECT c.compte,c.posdev
FROM v_sldoper c
WHERE c.compte IN ('11510198451','00610198451','40010198451','40010198453','00610198461','00101980081','00101980094',
'00101980111','40010198461','40010198462','40010198466','40010198463')
AND datpos = '31/12/21'
)t
ON t.compte = x.compte
Output result
I want the running balance in my query. I had wrote the query.
May be i am mistaking any where please let me know.
SELECT
ACC_VMAST.VM_DATE,
ACC_VDET.CHEQUE,
ACC_VMAST.NARRATION,
ACC_VDET.DEBIT,
ACC_VDET.CREDIT,
sum(nvl(ACC_VDET.DEBIT,0) - nvl(ACC_VDET.CREDIT,0) )
over (order by ACC_VMAST.VM_DATE , ACC_VDET.DEBIT ) running_bal
FROM ACC_VMAST,
ACC_VDET,
ACC_COA
WHERE ACC_VMAST.VM_PK=ACC_VDET.VM_PK
AND ACC_COA.COA_PK=ACC_VDET.COA_PK
AND ACC_VMAST.POST_BY IS NOT NULL
AND ACC_VMAST.CANCEL_STATUS IS NULL
AND ACC_VMAST.VM_DATE BETWEEN '07/06/2021' AND '07/07/2021'
AND ACC_VDET.COA_PK= '303'
ORDER BY ACC_VMAST.VM_DATE , ACC_VDET.DEBIT;
If you have rows that have the same values for the ORDER BY clause then when you SUM the values then all the rows with the same ORDER BY value will be grouped together and totalled.
To prevent that, you can add the ROWNUM pseudo-column to the ORDER BY clause of the analytic function so that there will not be any ties:
SELECT m.VM_DATE,
d.CHEQUE,
m.NARRATION,
d.DEBIT,
d.CREDIT,
SUM( COALESCE(d.DEBIT,0) - COALESCE(d.CREDIT,0) )
OVER ( ORDER BY m.VM_DATE, d.DEBIT, ROWNUM ) AS running_bal
FROM ACC_VMAST m
INNER JOIN ACC_VDET d
ON (m.VM_PK = d.VM_PK)
INNER JOIN ACC_COA c
ON (c.COA_PK = d.COA_PK)
WHERE m.POST_BY IS NOT NULL
AND m.CANCEL_STATUS IS NULL
AND m.VM_DATE BETWEEN DATE '2021-07-06' AND DATE '2021-07-07'
AND d.COA_PK = '303'
ORDER BY
m.VM_DATE,
d.DEBIT;
You need to add a row range with "rows between unbounded preceding and current row".
sum(nvl(ACC_VDET.DEBIT,0) - nvl(ACC_VDET.CREDIT,0) )
over (order by ACC_VMAST.VM_DATE , ACC_VDET.DEBIT rows between unbounded preceding and current row ) running_bal
we are using the below-mentioned minus query logic to find out the non-existing record between the 2 tables, is there an alternative logic that can be used via SQL to achieve the same this is causing performance issues and running for a very long time.
SELECT EMPLID,EMPL_RCD,EFFDT,HR_STATUS,EMPL_STATUS
FROM EDWHRSTG.PS_JOB_FULL_S
WHERE EMPLID = '09762931'
MINUS
SELECT EMPLID,EMPL_RCD,EFFDT,HR_STATUS,EMPL_STATUS
FROM SUODS.PS_JOB_S
WHERE EMPLID = '09762931'
You can try using an OUTER JOIN:
SELECT EMPLID,EMPL_RCD,EFFDT,HR_STATUS,EMPL_STATUS
FROM EDWHRSTG.PS_JOB_FULL_S a
LEFT OUTER JOIN (SELECT EMPLID,EMPL_RCD,EFFDT,HR_STATUS,EMPL_STATUS
FROM SUODS.PS_JOB_S
WHERE EMPLID = '09762931') b
ON b.EMPLID = a.EMPL_ID AND
b.EMPL_RCD = a.EMPL_RCD AND
b.EFFDT = a.EFFDT AND
b.HR_STATUS = a.HR_STATUS AND
b.EMPL_STATUS = a.EMPL_STATUS
WHERE b.EMPLID IS NULL AND
b.EMPL_RCD IS NULL AND
b.EFFDT IS NULL AND
b.HR_STATUS IS NULL AND
b.EMPL_STATUS IS NULL
However, I doubt this will perform any better. Your best option is to add an index on the five fields in play here (EMPL_ID, EMPL_RCD, EFFDT, HR_STATUS, EMPL_STATUS) to both tables, or in other words
CREATE INDEX EDWHRSTG.PS_JOB_FULL_S_1
ON EDWHRSTG.PS_JOB_FULL_S (EMPL_ID, EMPL_RCD, EFFDT, HR_STATUS, EMPL_STATUS);
and
CREATE INDEX SUODS.PS_JOB_S_1
ON SUODS.PS_JOB_S (EMPL_ID, EMPL_RCD, EFFDT, HR_STATUS, EMPL_STATUS);
You need to identify where time is being spent, in order to determine root cause if the performance problem; otherwise it’s just a guess.
An Active SQL Monitor report is your diagnostic tool of choice
I need output from the below two queries simultaneously in one output window.
QUERY 1
SELECT C.SERVICENAME, C.SERVICEID , B.SOAPIN, B.SOAPOUT, A.TIMESTAMP
FROM Schema1.LG_LOGENTRIES A, Schema1.LG_SOAPREQUESTS B, Schema1.CFG_SOAPSERVICES C
WHERE B.SERVICEID =C.SERVICEID AND
C.SERVICENAME <>'UploadAndPrepareDocumentEx1__sdweb_services_preload' AND
A.ID=B.LOGENTRYID AND B.TIMESTAMP BETWEEN TO_DATE('02/01/2018 11:55:00','dd/mm/yyyy hh24:mi:ss')
AND TO_DATE('02/01/2018 12:03:59','dd/mm/yyyy hh24:mi:ss') AND A.USERID IN (SELECT ID FROM Schema1.CFG_USERS
WHERE NAME=UPPER(TO_CHAR('CGBXGVSG')));
Query 2
SELECT B.JSONIN, B.JSONOUT, A.TIMESTAMP, B.EVENT_MESSAGE, A.PROCESSID, A.status, A.SERVERNAME
FROM Schema1.LG_LOGENTRIES A, Schema1.LG_EVENT B
WHERE B.EVENT_MESSAGE NOT IN ('getFileImage','submitBase64','loadDocumentToSign','getRefData') AND
A.ID=B.LOG_ENTRYID AND B.TIMESTAMP BETWEEN TO_DATE('31/12/2017 13:43:00','dd/mm/yyyy hh24:mi:ss')
AND TO_DATE('31/12/2017 13:53:59','dd/mm/yyyy hh24:mi:ss') AND A.USERID IN (SELECT ID FROM Schema1.CFG_USERS
WHERE NAME=UPPER(TO_CHAR('CTHX8Y2G')));
Run with F5 - you'll get both queries' output in the script panel.
I talk about how this differs here
UNION might be one option, but you'll have to
uniform both column lists (i.e. they have to return the same number of columns which have to be of the same data type), which means that you'd have to add certain NULL columns to both queries
include additional identifier so that you'd know which SELECT returned which values
If you wanted to have them side-by-side, huh, that's not that easy. Thinking loudly: you'd have to have a column that joins those values. Those SELECTs would be inline views. You'd use an aggregate function (such as MAX) along with a DECODE (or CASE) to select values from both queries. Shortly: too much pain.
Now, why do you want to do that? What's wrong with two separate windows, placed side by side?
[EDIT] Showing example of how UNION might look like
select c.servicename, c.serviceid, b.soapin, b.soapout, a.timestamp, to_char(null), to_char(null), to_char(null) , to_number(null), to_char(null), to_char(null)
from ... the rest of your 1st query
union
select null , null , null , null , a.timestamp, b.jsonin , b.jsonout , b.event_message, a.processid , a.status , a.servername
from ... the rest of your 2nd query
I have a table that has (for example) 4 columns.
pk_table_id INT NOT NULL
username VARCHAR(100) NOT NULL
start_date DATETIME NOT NULL
end_date DATETIME NULL
My requirement is to return all rows in descending order of end_date - BUT the NULL values must be first, and then descending order of start_date.
I've done it in SQL - but could someone assist me with a LINQ version to do this?
This is the SQL query we use:
SELECT [person_employment_id]
, [party_id]
, [employer_name]
, [occupation]
, [telephone]
, [start_date]
, [end_date]
, [person_employment_type_id]
, [person_employment_end_reason_type_id]
, [comments]
, [deleted]
, [create_user]
, [create_date]
, [last_update_user]
, [last_update_date]
, [version]
FROM [dbo].[person_employment]
WHERE ([party_id]=#party_id)
ORDER BY ISNull([end_date],'9999-DEC-31') DESC, [start_date] DESC
For this problem, you could do a null check on the end_date and use that result as the ordering. So you don't need to use the same SQL constructs to achieve this, but rather use one more natural in your language of choice (C# I'm assuming).
var query =
from row in dc.Table
let isEndDateNull = row.end_date == null
orderby isEndDateNull descending, row.start_date descending
select row;
