I want to select few data from a Oracle table of June month(June 1st to June 30th of 2017) and the start date will be from tomorrow(Sep 13th). Hence I wrote a query in below format,
select * from table where column1='Data1' and Column2='Data2'
and trunc(DateTime) between trunc(sysdate-104) and trunc(sysdate-75)
I'm not able to check this query as I don't have tool for this. I just wrote it in notepad and want to share to my friend.
My Question - Will trunc(DateTime) between trunc(sysdate-104) and trunc(sysdate-75) condition will give data between June1st to June31 or Does any Syntax issue there?
There is no problem with the syntax itself even though your formulation is time sensitive, which means that tomorrow it won't return the same result.
Instead, go with something like this :
AND TRUNC(DateTime) BETWEEN to_date('2016-06-01','YYYY-MM-DD')
AND to_date('2016-06-30','YYYY-MM-DD')
Just cast the date format to month/year and compare against that.
select *
from table
where column1 = 'Data1'
and column2 = 'Data2'
and to_char(DateTime, 'MMYYYY') = '062017';
Hi I think the most accurate would be:
select * from table where column1='Data1' and Column2='Data2'
AND DateTime BETWEEN TRUNC(sysdate-104)
AND TRUNC(sysdate-75)
+ interval '23' hour
+ interval '59' minute
+ interval '59' second;

i have a problem with a date parameter query using 'between' operator in oracle view, when i do this query :
SELECT *
FROM MY_VIEW
WHERE STATUS = 'Active'
AND CHECKER_DATE BETWEEN to_date(sysdate - 1, 'DD-MON-YY') AND to_date(sysdate, 'DD-MON-YY');
it does not give me the records (actualy i have any record on that date).
I try using 'in' operator, but still not give me the records.
Please throw some information for this.
*checker_date defined as date
Your first error is to call to_date() on a value that is already a DATE. to_date() expects a VARCHAR value, so sysdate will be first converted to VARCHAR and will then immediately be converted back to a DATE value which it was to begin with.
You probably want
AND CHECKER_DATE BETWEEN trunc(sysdate) - 1 AND trunc(sysdate)
Most probably this will still not give you want you want as that would not include rows from "today". trunc(sysdate) means "today at midnight" and any row that was created today after midnight will not be included. With date/time values (and Oracle's DATE type does contain a time, despite the name) it's better to not use BETWEEN, but explicit range operators instead:
AND CHECKER_DATE >= trunc(sysdate) - 1
AND CHECKER_DATE < trunc(sysdate) + 1
trunc(sysdate) + 1 is tomorrow at midnight, so any value that is (strictly) smaller than that is "today".
All the above assumes that CHECKER_DATE is defined as DATE or TIMESTAMP
You can try:
SELECT *
FROM MY_VIEW
WHERE STATUS = 'Active'
AND CHECKER_DATE BETWEEN trunc(sysdate - 1) AND trunc(sysdate);
Oracle advises against using to_date for date. Also trunc is here because Trunc removes the time component.
may be records are not 'Active' or 'Active' a not-existing value in one of the reference tables if any and trunc(sysdate -1) and trunc(sysdate) would help
I get some data through a OSB Proxy Service and have to transform that using Xquery. Earlier the transformation was done on the database but now it is to be done on the proxy itself. So I have been given the SQL queries which were used and have to generate Xquery expressions corresponding to those.
Here is the SQL query which is supposed to find the difference between 2 dates.
SELECT ROUND((CAST(DATEATTRIBUTE2 AS DATE) -
CAST(DATEATTRIBUTE1 AS DATE) ) * 86400 ) AS result
FROM SONY_TEST_TABLE;
DATEATTRIBUTE1 and DATEATTRIBUTE2 are both of TIMESTAMP type.
As per my understanding this query first casts the TIMESTAMP to DATE so that the time part is stripped then subtracts the dates. That difference in days in multiplied with 86400 to get the duration in seconds.
However, when I take DATEATTRIBUTE2 as 23-02-17 01:17:19.399000000 AM and DATEATTRIBUTE1 as 23-02-17 01:17:18.755000000 AM the result should ideally be 0 as the dates are same and i'm ignoring the time difference but surprisingly the result comes as 1. After checking I found that the ( CAST(DATEATTRIBUTE2 AS DATE) - CAST(DATEATTRIBUTE1 AS DATE) ) part aparently does not give an integer value but a fractional one. How does this work?? o_O
Any help is appreciated. Cheers!
EDIT : So got the problem thanks to all the answers! Even after casting to DATE it still has time so the time difference is also calculated. Now how do I implement this in XQuery? See this other question.
Oracle DATE datatype is actually a datetime. So casting something as a date doesn't remove the time element. To do that we need to truncate the value:
( trunc(DATEATTRIBUTE2) - trunc(DATEATTRIBUTE1) )
you should try this to find difference by day
SELECT (trunc(DATEATTRIBUTE2) -
trunc(DATEATTRIBUTE1) ) AS result
FROM SONY_TEST_TABLE;

you can use extract like below:
SELECT ROUND (
EXTRACT (MINUTE FROM INTERVAL_DIFFERENCE) / (24 * 60)
+ EXTRACT (HOUR FROM INTERVAL_DIFFERENCE) / 24
+ EXTRACT (DAY FROM INTERVAL_DIFFERENCE))
FROM (SELECT ( TO_TIMESTAMP ('23-02-17 01:17:19', 'dd-mm-yy hh24:mi:ss')
- TO_TIMESTAMP ('23-02-17 01:17:17', 'dd-mm-yy hh24:mi:ss'))
INTERVAL_DIFFERENCE
FROM DUAL)
I need to query 2 tables, one contains a TIMESTAMP(6) column, other contains a DATE column. I want to write a select statement that prints both values and diff between these two in third column.
SB_BATCH.B_CREATE_DT - timestamp
SB_MESSAGE.M_START_TIME - date
SELECT SB_BATCH.B_UID, SB_BATCH.B_CREATE_DT, SB_MESSAGE.M_START_TIME,
to_date(to_char(SB_BATCH.B_CREATE_DT), 'DD-MON-RR HH24:MI:SS') as time_in_minutes
FROM SB_BATCH, SB_MESSAGE
WHERE
SB_BATCH.B_UID = SB_MESSAGE.M_B_UID;
Result:
Error report -
SQL Error: ORA-01830: date format picture ends before converting entire input string
01830. 00000 - "date format picture ends before converting entire input string"
You can subtract two timestamps to get an INTERVAL DAY TO SECOND, from which you calculate how many minutes elapsed between the two timestamps. In order to convert SB_MESSAGE.M_START_TIME to a timestamp you can use CAST.
Note that I have also removed your implicit table join with an explicit INNER JOIN, moving the join condition to the ON clause.
SELECT t.B_UID,
t.B_CREATE_DT,
t.M_START_TIME,
EXTRACT(DAY FROM t.diff)*24*60 +
EXTRACT(HOUR FROM t.diff)*60 +
EXTRACT(MINUTE FROM t.diff) +
ROUND(EXTRACT(SECOND FROM t.diff) / 60.0) AS diff_in_minutes
FROM
(
SELECT SB_BATCH.B_UID,
SB_BATCH.B_CREATE_DT,
SB_MESSAGE.M_START_TIME,
SB_BATCH.B_CREATE_DT - CAST(SB_MESSAGE.M_START_TIME AS TIMESTAMP) AS diff
FROM SB_BATCH
INNER JOIN SB_MESSAGE
ON SB_BATCH.B_UID = SB_MESSAGE.M_B_UID
) t
Convert the timestamp to a date using cast(... as date). Then take the difference between the dates, which is a number - expressed in days, so if you want it in minutes, multiply by 24*60. Then round the result as needed. I made up a small example below to isolate just the steps needed to answer your question. (Note that your query has many other problems, for example you didn't actually take a difference of anything anywhere. If you need help with your query in general, please post it as a separate question.)
select ts, dt, round( (sysdate - cast(ts as date))*24*60, 2) as time_diff_in_minutes
from (select to_timestamp('2016-08-23 03:22:44.734000', 'yyyy-mm-dd hh24:mi:ss.ff') as ts,
sysdate as dt from dual )
;

We want to select data from table with below condition.
Date of Transactiontime <= (Current Date - n Days)
for e.g.
Today is - 2016-06-21.
Date of Transactiontime = '2016-06-19 11:45:07.148'.
With below query we could get Data which is 2 days older.
Query:
SELECT * FROM T WHERE FORMATDATETIME (Transactiontime,'YYYY-MM-d') <= FORMATDATETIME ( DATEADD('HH',-2*24,Now()), 'YYYY-MM-d');
Dataype of Transactiontime = TIMESTAMP
Is there any better way to get the same results?
Have you tried function DATEDIFF()?
SELECT * FROM T WHERE DATEDIFF('DAY', NOW(), Transactiontime) >= 2
EDIT
Might be better using DAY_OF_YEAR instead of DAY.
first... sorry for my english.
I have a query like this:
Select *
From tableA
Where (
TO_NUMBER(TO_CHAR(dateA(+),'SYYYY')) = 2013
AND TO_NUMBER(TO_CHAR(dateA(+),'MM')) = 02
AND to_number(to_char(dateA(+),'dd')) <= 25
)
and retrieve me the data from each date until last number that I give as parameter, in this case the day 25. This working but delay very much because the form of "Where" statement... anybody know another way that retrieve the data so fast and with the same functionality?
It sounds like you want
SELECT *
FROM tableA
WHERE dateA BETWEEN trunc( date '2013-02-26', 'MM' ) AND date '2013-02-26'
This will return all the rows where dateA is between the first of the month and the specified date. If there is an index on dateA, Oracle would be able to use it for this sort of query (though whether it actually would is a separate issue).
