I have a problem with filtering date. I have SQL-query which are displayed all required parameters in certain date. I think that I also need create query which will return the same parameters, but with several required date.
Example: now in my query "2020-12-06", "2021-12-06". But I wanna get all data for period "2020-12-06" - "2021-12-06"
I tried create something, but best that I have - displaying for date which set, but not displaying period:
select ledgeraccounttypeid, dateeffective, sum(amount) from ledgertransaction
where ledgeraccounttypeid in (2,1,16) and dateeffective in('2020-12-06', '2021-12-06')
group by ledgeraccounttypeid, dateeffective
*Important: Period will set from program
**I will have: "YYYY.MM.DD" OR "YYYY.MM.DD - YYYY.MM.DD".
Do you want between?
where dateeffective between date '2020-12-06' and date '2021-12-06'
This assumes that dateeffective is of a date-like datatype, as it should be.
In many cases, half-open intervals better fit the needs:
where
dateeffective >= date '2020-12-06'
and dateeffective < date '2021-12-06' + interval '1' day
This syntax would work in both Postgrs and MySQL, also in the latter we would dispense the date keyword to introduce literal dates.

I have the following Oracle Query that is converting todays date and the date field from the table into the same format. However, when trying to compare the two they aren't coming up as equal.
CAST(dstamp As Date), TO_DATE(CURRENT_DATE,'dd-MON-YY HH24.MI.SS','NLS_DATE_LANGUAGE = American')
The cast is used on the field in my table, both these return.
However, when adding the following where statement no rows are returned. I can't work out why these wouldn't be classed as equal?
WHERE CAST(dstamp As Date) = TO_DATE(CURRENT_DATE,'dd-MON-YY HH24.MI.SS','NLS_DATE_LANGUAGE = American');
Any help appreciated.
If you are trying to check if dstamp belongs to the current day, I would suggest:
where dstamp >= trunc(sysdate) and dstamp < trunc(sysdate) + 1
Athough a bit more verbose, this will be more efficient than applying a date function on the column being compared. Using a function on a column in a predicate makes the query non-SARGable, ie it cannot take advantage of an existing index.
The date is ALREADY a date. You don't need to convert it. You may need to remove the time component. Does this do what you want?
WHERE TRUNC(dstamp) = TRUNC(sysdate)
I want to search for data between given dates. I'm able to get results that are between but it's not including the day at the beginning and end of between statement.
I tried just switching the days that use the between on such as adding or subtracting a day, but there's gotta be another way.
SQL:
WHERE "Date" Between '09/02/2019' AND '09/06/2019'
AND (sf.TemplateName = 'Nassco Lacp')
AND (sf.ProjectName = 'Crossbore Safety Program')
AND (sf.WorkOrderNumber LIKE '%2715%I1%')
I should get all data between those days including the work done on the the second and sixth, but for some reason I'm not getting stuff done on the sixth. HELP!
Don't use between with dates! The time component can cause a problem. Instead:
where date >= '2019-09-02' and
date < '2019-09-07' and -- note this is one day later
. . .
Most databases understand the YYYY-MM-DD for date constants.
In my experience this happends when the Date field is a timestamp data type. What happends is that a specific date such as 09/02/2019 it's interpreted as 09/02/2019 00:00:00 so any value before is exclured.
Try (ORACLE DBMS):
WHERE Trunc("Date") Between '09/02/2019' AND '09/06/2019'
Try (SQL Server):
WHERE cast("Date" As Date) Between '09/02/2019' AND '09/06/2019'
I am casting mm/dd/yy strings into dates in redshift using CAST AS DATE CAST(birth_str AS DATE) AS birth_date. The conversion handles the components correctly but the year is being converted into future times whenever it falls below 1970. For example:
birth_str birth_date
07/19/84 1984-07-19
02/07/66 2066-02-07
06/24/84 1984-06-24
01/31/64 2064-01-31
12/08/62 2062-12-08
02/21/36 2036-02-21
02/19/37 2037-02-19
07/01/74 1974-07-01
08/25/50 2050-08-25
08/31/39 2039-08-31
Is there a best practice for getting dates to not fall into the future?
Is there not an argument for this in the cast? (I looked everywhere but I am finding nothing.) Otherwise, I am envisioning the best path forward is testing for the cast date being in the future and then just doing string surgery on the miscreants before recasting them into reasonable dates.
Basically:
if not future date: great.
if future date:
peel out all the date components
slap a 19 onto the yy
glue everything back together
cast into date.
Is this as good as it gets? (I was a bit surprised I could find no one has come up with a better way around this issue already.)
Is there a best practice? Absolutely! Don't store dates as strings. Store dates as date. That is why SQL has native types.
In your case, you could use conditional logic:
select (case when cast(birth_str AS DATE) < current_date
then cast(birth_str AS DATE)
else cast(birth_str AS DATE) - interval '100 year'
end) as birth_date
Or since Redshift can't handle intervals you can go with this:
SELECT (CASE
WHEN birth_str::DATE < CURRENT_DATE
THEN birth_str::DATE
ELSE ADD_MONTHS(birth_str::DATE, -1200)
END) AS birth_date
You can apply a CASE to check the converted DATE IS greater than TODAY or not. If Yes, Just minus 100 years from the results as below.
One Question: Is there any chance of having dates like 02/21/14 which can be belongs to 1900 or 2000?
SELECT
CASE
WHEN CAST('02/21/36' AS DATE) >GETDATE() THEN DATEADD(YY,-100,CAST('02/21/36' AS DATE))
ELSE CAST('02/21/36' AS DATE)
END
My table "Message" contain a column name : message_date (datatype : TIMESTAMP) which stores date and time. But in this case, I would like to only show the date of the data, so I use the method to_char(case(message_date as date),'DD-MM-YYYY')
SELECT msg_id, msg_details, to_char(cast(message_date as date) ,'DD-MM-YYYY')as "DATE"
FROM message
WHERE message LIKE '%hi%'
AND to_char(cast(message_date as date), 'DD-MM-YYYY')
BETWEEN '15-01-2018'
AND '30-01-2018'
I would like to show only the row between the date 15-01-2018 and 30-01-2018. But in the end, the query result came out with the data which from date 15 - 30..where row with other month (exp: 20-03-2018 also shown in the result. I not sure why it only check for the date and not together with month and year...
Seek for help ..thanks
Use date literals with the dates in an ISO compliant format:
WHERE
message LIKE '%hi%' AND
message_date BETWEEN date '2018-01-15' AND date '2018-01-30'
Notr that you don't need to cast message_date to text, because it is already a timestamp and can be directly compared to dates.
The only issue with using BETWEEN when comparing dates is if one or more of the dates you're comparing has a time portion. For example, the date 30-JAN-18 01.32.32 PM certainly isn't between 15-JAN-18 and 30-JAN-18 - it's greater (er, later) than the latter date. Plus while using BETWEEN, which is inclusive, there is always the chance of including an edge case you didn't intend. My recommendation would be to do something like this:
SELECT msg_id, msg_details, TO_CHAR(message_date, 'DD-MM-YYYY') AS "DATE"
FROM message
WHERE message LIKE '%hi%'
AND message_date >= DATE'2018-01-15'
AND message_date < DATE'2018-01-30' + 1;
Notice in the first line I got rid of your CAST() - there is no reason to cast a date value to the DATE datatype. In the last line I'm using a bit of Oracle date arithmetic; this will give me all dates up to and including 30-JAN-18 11:59.59.9999.....
As an aside you might want to apply the LOWER() function to message in your WHERE clause:
WHERE LOWER(message) LIKE '%hi%'
otherwise you will miss messages containing Hi, HI, hI, etc.
I have a table with a LOAD_STRT_DTM colum. This is a date column and values are like this - 18-JUL-14 08.20.34.000000000 AM.
I want to find the data which came before 5 days.
My logic is -
Select * from Table where 24 *(To_DATE(Sysdate,'DD-MM-YY') - To_DATE(LOAD_STRT_DTM,'DD-MM-YY')) >120
The issue is -
Select (To_DATE(Sysdate,'DD-MM-YY') - To_DATE(LOAD_STRT_DTM,'DD-MM-YY')) from table
This query should give the NumberOfDays between two dates. But this is not working, I Doubt, the issue is because of the format of the LOAD_STRT_DTM colum.
Please let me know where i am doint it wrong.
If your column is DATE datatype everything is ok, just shoot an:
select * from table where LOAD_STRT_DTM > sysdate - 5;
No need to convert dates to DATE datatype.
(To_DATE(Sysdate,'DD-MM-YY') - To_DATE(LOAD_STRT_DTM,'DD-MM-YY'))
You don't have to convert a DATE into a DATE again. IT is already a DATE. You just need to use it for date calculations. You use TO_DATE to convert a STRING into a DATE.
For example, if you have a string value like '18-JUL-14', then you would need to convert it into date using TO_DATE. Since your column is DATE data type, you just need to use as it is.
This is a date column
I want to find the data which came before 5 days.
Simply use the filter predicate as:
WHERE load_strt_dtm > SYSDATE - 5;
NOTE : SYSDATE has both date and time elements, so it will filter based on the time too. If you want to use only the date part in the filter criteria, then you could use TRUNC. IT would truncate the time element.
I have answered a similar question, have a look at this https://stackoverflow.com/a/29005418/3989608
It looks like LOAD_STRT_DTM is a TIMESTAMP rather than a DATE, given the number of decimal points following the seconds. The only thing you have to be cautious about is that Oracle will convert a DATE to a TIMESTAMP implicitly where one of the operands is a TIMESTAMP. So the solution
WHERE load_strt_dtm > SYSDATE - 5
will work; as will
WHERE load_strt_dtm + 5 > SYSDATE
but the following will not:
WHERE SYSDATE - load_start_dtm < 5
the reason being that TIMESTAMP arithmetic produces an INTERVAL rather than a NUMBER.
first convert two dates to same format select datediff(dd,convert(varchar(20),'2015-01-01',112),convert(varchar(20),'01-10-2015',112))
