i will get latest record by timestamp but it is not filter desired
output
here is code i was try to get latest record bu it is not work me.i will attach a image for better understanding.can you figure out that problems
select *
from (select
id,NPCI_REFMSGID,TO_CHAR (created_date, 'dd.mm.rrrr hh24:mi:ss.ff3')AS created_Date,
rank() over (partition by ID order by TO_CHAR (created_date, 'dd.mm.rrrr hh24:mi:ss.ff3') desc) r
from emnd_tblemandate_mst
--where end_enrollment_date is null
)
where r = 1 AND NPCI_REFMSGID='1ea345bc63644b53a88076040ef979e3'
You are partitioning by ID so you get all rows in your result.
Think it should be
select *
from (select id
, NPCI_REFMSGID
, TO_CHAR (created_date, 'dd.mm.rrrr hh24:mi:ss.ff3')AS created_Date
, rank() over (partition by NPCI_REFMSGID order by created_date desc) r
from emnd_tblemandate_mst
)
where r = 1
AND NPCI_REFMSGID = '1ea345bc63644b53a88076040ef979e3'
Then you get only the newest record for a specific NPCI_REFMSGID
I wanted to select the rows whose date is greater than last processed date.
The last processed date is in hist table.
select id
from table1
where to_date(last_updated_date,'MM/DD/YYYY HH24:MI:SS')
> select to_date(nvl(max(last_updated_date),sysdate),'MM/DD/YYYY HH24:MI:SS')
from table1_hist;
This return ORA-01843: not a valid month error.
I had manually inserted row in table1 as TO_DATE('09/26/2019 14:37:49', 'MM/DD/YYYY HH24:MI:SS') while in table1_hist there are no rows.
But when I query the table using sql developer for table1 I get the value appearing as '26-SEP-19'. last_updated_date is a date field.
I wanted to to get the id's from table1 after the last executed time.
Thanks
SYSDATE is a DATE value. Using TO_DATE() on a value which is already a DATE is useless.
Try
where last_updated_date >
(select MAX(NVL(last_updated_date, SYSDATE)) from table1_hist);
I will suggest using an analytical function as following:
SELECT
ID
FROM
(
SELECT
T.ID,
T.LAST_UPDATED_DATE,
MAX(TH.LAST_UPDATED_DATE) OVER() AS M_LAST_UPDATED_DATE
FROM
TABLE1 T
JOIN TABLE1_HIST TH ON ( T.ID = TH.ID )
-- i am guessing that this is the join condition or you can use your own conition here
)
WHERE
LAST_UPDATED_DATE > COALESCE(M_LAST_UPDATED_DATE, SYSDATE)
Cheers!!
First of all, you don't need any to_date conversion for comparison.
If table1_hist has at least one non-null value, then using
select t.id
from table1 t
where t.last_updated_date > ( select max(th.last_updated_date) from table1_hist th )
is enough, but all those values are null then use a query such as this :
select t.id
from table1 t
where t.last_updated_date >
(select nvl(max(th.last_updated_date),t.last_updated_date-1) from table1_hist th)

I am using following query.
SELECT SYSDATE,(SELECT P_PRICE_OPEN FROM GTT_ADJ_PRICE_TABLE WHERE FSYM_ID='P8R3C2-R' AND P_DATE='22-OCT-18' AND P_VOLUME<>0 AND ROWNUM=1) FROM DUAL;
GTT_ADJ_PRICE_TABLE is global temporary table loaded with values when i have executed a function related to it. This GTT preserves rows after commit. This query gives me correct results.
But, If i run the query
SELECT WEEK_END, WEEK_START,
(SELECT P_PRICE_OPEN FROM GTT_ADJ_PRICE_TABLE WHERE P_DATE=WEEK_START) AS WEEKS_OPEN_PRICE,
(SELECT MAX(P_PRICE_HIGH) FROM GTT_ADJ_PRICE_TABLE WHERE FSYM_ID=FID AND P_DATE<=WEEK_END
AND P_DATE>=WEEK_START AND P_VOLUME<>0) AS WEEKLY_HIGH,
(SELECT MIN(P_PRICE_LOW) FROM GTT_ADJ_PRICE_TABLE WHERE FSYM_ID=FID AND P_DATE<=WEEK_END
AND P_DATE>=WEEK_START AND P_VOLUME<>0) AS WEEKLY_LOW,
(SELECT SUM(P_VOLUME) FROM GTT_ADJ_PRICE_TABLE WHERE FSYM_ID=FID AND P_DATE<=WEEK_END
AND P_DATE>=WEEK_START AND P_VOLUME<>0) AS WEEKLY_VOLUME,
P_PRICE
FROM (
SELECT ROWNUM,FID,WEEK_END,P_VOLUME,P_PRICE,
(SELECT P_DATE FROM FP_V2_FP_BASIC_PRICES WHERE FSYM_ID=FID AND P_DATE>=TRUNC(WEEK_END, 'IW') AND P_VOLUME<>0 AND ROWNUM=1) AS WEEK_START
FROM (
SELECT
ROWNUM,FSYM_ID AS FID, WEEK_END,P_VOLUME, P_PRICE,P_PRICE_OPEN,P_PRICE_HIGH,P_PRICE_LOW
FROM (
SELECT ROWNUM,FSYM_ID,P_DATE AS WEEK_END, P_PRICE,P_VOLUME, P_PRICE_OPEN,P_PRICE_HIGH,P_PRICE_LOW,
CASE
WHEN (TO_CHAR(P_DATE,'D') >= AVG(TO_CHAR(P_DATE,'D')) OVER (order by P_DATE DESC rows between 1 preceding and current row) and ROWNUM>=1) or TO_CHAR(P_DATE,'D')=6
THEN 1
ELSE 0
END AS WEEKFLAG
FROM(
SELECT * FROM TABLE (ADJUSTED_PRICE('P8R3C2-R')) WHERE P_VOLUME<>0
)
)WHERE WEEKFLAG=1
)
);
It gives me NULL in WEEKS_OPEN_PRICE,WEEKLY_HIGH,WEEKLY_LOW,WEEKLY_VOLUME.
Please help me to resolve the issue. Thanks in anticipation.
Try with WITH clause. I hope a below query works. I don't have possibility to check.
WITH adjustedPrice AS (
SELECT *
FROM TABLE(adjusted_price('P8R3C2-R'))
WHERE p_volume <> 0
AND TO_CHAR(p_date, 'DY') NOT IN ('SAT', 'SUN')
)
SELECT ap.week,
ap.week_start,
ap.week_end,
ap.weeks_high_price,
ap.weeks_low_price,
ap.weekly_volume,
ws.p_price_open AS weeks_open_price,
we.p_price AS weeks_close_price
FROM (
SELECT TRUNC(p_date, 'IW') AS week,
TRUNC(MIN(p_date)) AS week_start,
TRUNC(MAX(p_date)) AS week_end,
MAX(p_price_high) AS weeks_high_price,
MIN(p_price_low) AS weeks_low_price,
SUM(p_volume) AS weekly_volume
FROM adjustedPrice
GROUP BY TRUNC(p_date, 'IW')
) ap
INNER JOIN adjustedPrice ws ON ws.p_date = ap.week_start
INNER JOIN adjustedPrice we ON we.p_date = ap.week_end
ORDER BY week DESC;
Wanted to post as a comment. But it wont fit there thats why writing it as an answer.
I tried this code to get the week start, end , weeks high price, weeks low price, weekly volume.
select
trunc("P_DATE", 'IW') as week,
min(trunc("P_DATE")) as week_start,
max(trunc("P_DATE")) as week_end,
MAX(P_PRICE_HIGH) AS WEEKS_HIGH_PRICE,
MIN(P_PRICE_LOW) AS WEEKS_LOW_PRICE,
SUM(P_VOLUME) AS WEEKLY_VOLUME
from TABLE
(ADJUSTED_PRICE('P8R3C2-R'))
WHERE
P_VOLUME<>0 AND to_char("P_DATE", 'DY') not in ('SAT','SUN')
group by
trunc("P_DATE", 'IW')
ORDER BY
trunc("P_DATE", 'IW') DESC;
That gave me results in hardly 2-4 seconds. But i want to get the weeks open price where date will be equal to WEEK_START and weeks closing price where date will be equal to WEEK_END.
I tried following approach for the same. But its taking too much time (like 300+ seconds).
SELECT
WEEK,WEEK_START, WEEK_END, WEEKS_HIGH_PRICE,WEEKS_LOW_PRICE,WEEKLY_VOLUME,
(SELECT P_PRICE_OPEN FROM TABLE (ADJUSTED_PRICE('P8R3C2-R')) WHERE P_VOLUME<>0 AND P_DATE=WEEK_START) AS WEEKS_OPEN_PRICE,
(SELECT P_PRICE FROM TABLE (ADJUSTED_PRICE('P8R3C2-R')) WHERE P_VOLUME<>0 AND P_DATE=WEEK_END) AS WEEKS_CLOSE_PRICE
FROM
(
select
trunc("P_DATE", 'IW') as week,
min(trunc("P_DATE")) as week_start,
max(trunc("P_DATE")) as week_end,
MAX(P_PRICE_HIGH) AS WEEKS_HIGH_PRICE,
MIN(P_PRICE_LOW) AS WEEKS_LOW_PRICE,
SUM(P_VOLUME) AS WEEKLY_VOLUME
from TABLE
(ADJUSTED_PRICE('P8R3C2-R'))
WHERE
P_VOLUME<>0 AND to_char("P_DATE", 'DY') not in ('SAT','SUN')
group by
trunc("P_DATE", 'IW')
ORDER BY
trunc("P_DATE", 'IW') DESC
);
If anybody can help me to improve the output time is most welcome.
select A.*
from Incident_Audit_log a where incident_audit_log_id in
(select top 1 incident_audit_log_id from Incident_Audit_log b
where b.incident_id=a.incident_id and b.status_did=a.status_did
and b.tracking_code_did = (select tracking_code_did
from Incident_Audit_log where update_date = (select MAX(update_date)
from Incident_Audit_log where Status_did in (103, 1035)
and incident_id = b.incident_id)
and incident_id = b.incident_id)
order by update_date asc)
I am not sure what you want to achieve but I guess that you want to extract row with new newest update and status_did equal to 13 and 1035.
In that case this should work:
select *
from (
select ROW_NUMBER() OVER(ORDER BY update_date DESC) AS rn,
*
from Incident_Audit_log
where status_did in (103, 1035)
) as SubQueryAlias
where rn = 1
In case not , provide more info.
I am have a table with 500k transactions. I want to fetch the last balance for a particular date. So I have have returned a query like below.
SELECT curr_balance
FROM transaction_details
WHERE acct_num = '10'
AND is_deleted = 'N'
AND ( value_date, srl_num ) IN(
SELECT MAX( value_date ), MAX( srl_num )
FROM transaction_details
WHERE TO_DATE( value_date, 'dd/mm/yyyy' )
<= TO_DATE( ADD_MONTHS( '05-APR-2012', 1 ), 'dd/mm/yyyy' )
AND acct_num = '10'
AND is_deleted = 'N'
AND ver_status = 'Y' )
AND ver_status = 'Y'
This has to be executed for incrementing of 12 months to find the last balance for each particular month. But this query is having more cpu cost, 12 times it is taking huge time. How to remodify the above query to get the results in faster way. Whether this can be broken into two part in PL/SQL to achieve the performance. ?
Try:
select * from(
SELECT value_date, srl_num, curr_balance
FROM transaction_details
WHERE acct_num = '10'
AND is_deleted = 'N'
AND ver_status = 'Y'
row_number() over (partition by trunc(value_date - interval '5' day,'MM')
order by srl_num desc
) as rnk
)
where rnk = 1;
You'll get a report with the ballance on last srl_num on each month in your table.
The benefit is that your approach scans the table 24 times for 12 months report and my approach scans the table once.
The analytic function gets the rank of record in current month(partition by clause) ordering the rows in the month after srl_num.
You don't have to query your table twice. Try using analytic functions
SELECT t.curr_balance
-- , any other column you want as long it is in the subselect.
FROM (
SELECT
trans.curr_balance
, trans.value_date
-- any other column you want
, trans.srl_num
, MAX(trans.srl_num) OVER(PARTITION BY trans.value_date, trans.srl_num) max_srl_num
, MAX(trans.value_date) OVER(PARTITION BY trans.value_date, trans.srl_num) max_date
FROM transaction_details trans
WHERE TO_DATE( value_date, 'dd/mm/yyyy' ) <= TO_DATE( ADD_MONTHS( '01-APR-2012', 1 ), 'dd/mm/yyyy' )
AND acct_num = '10'
AND is_deleted = 'N'
AND ver_status = 'Y'
) t
WHERE t.max_date = t.value_date
AND t.max_srl_num = t.srl_num
A couple of thoughts.
Why do you have TO_DATE( value_date...? Isn't your data type DATE? this might be breaking your index if you have one in that column.
Note that (this is a wild guess) if your srl_num is not the highest for the latest date, you will have incorrect results and might not return any rows.
