I would like to get some help in regards of automating my query.
The goal is to get the latest data, everyday the data refreshes but the start date should remain the same.
For example: Start date is Jan 1 2023, but the todays end date should be Jan 13 2023, and next day it will be Jan 14 2023, but the start date stays the same (Jan 1st 2023).
I have tried the following query but it keeps running and do not provide any output. the query I am using is hive SQL and hoping if anyone can help this.
SELECT *
FROM table_a
WHERE cast(entered_date as date) >= '20230101'
and cast(entered_date as date) < date_add(current_date(),0)
You can use date_format(DATE|TIMESTAMP|STRING ts, STRING fmt) to convert value to string in the date format. You can find the description of the function from here. Therefore if you want the output between your desired date and not beyond the current date you can query like this
SELECT *
FROM table
WHERE DATE_FORMAT(entered_date, 'yyyyMMdd') >= '20230101'
AND DATE_FORMAT(entered_date, 'yyyyMMdd') <= DATE_FORMAT(CURRENT_DATE(), 'yyyyMMdd');
I'm having issues in my WHERE clause selecting data from a specific day to today's date. The day/time format in my date column is '7/2/2020 3:12:08 PM'.
I've tested a couple options but keep getting this error - 'literal does not match format string'.
Any idea's of how I can select all data from March 1, 2020 to current date?
Thanks!
In Oracle date columns are not strings, they are exactly in date datatype, so you don't need to convert/cast it. Just use simple date literals:
https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/Literals.html#GUID-8F4B3F82-8821-4071-84D6-FBBA21C05AC1
select * from table where your_date_columg >= date'2015-12-31'
or with to_date function for your string:
select * from table
where
your_date_columg >= to_date('2019-11-25 13:57:52',
'yyyy-mm-dd hh24:mi:ss')
I have a table which is fed two different date formats:
d/m/Y & m/d/Y. The date format wanted is d/m/Y
I am able to select the date column and do a check and format if the date is in the wrong format.
This is my current SQL query:
SELECT COALESCE(TRY(date_format(date_parse(tbl.date, %d/%m/%Y), %d/%m/%Y)),
TRY(date_format(date_parse(tbl.date, %m/%d/%Y), %d/%m/%Y))) as date
FROM xxx
That fixes the mismatched dates...however I also need to query a date range e.g. the last 7 days.
If I add a WHERE statement it does not execute as I have already queried the date earlier.
How can I format my dates AND filter based on a given range (last 7 days)?
In ANSI SQL -- implemented by Presto, which Athena is based on -- the WHERE clause cannot reference the SELECT projections, so you need a aubquery:
SELECT *
FROM (
SELECT COALESCE(TRY(date_parse ....... AS date
FROM xxx
)
WHERE date > current_date - INTERVAL '7' DAY
I have a column in my table that stores a date in format (DD-MM-YY HH:MM:SS). For e.g.:
05-06-15 01:02:03
I need to output for instance all the records that have a date between the 4th and the 5th of June, so i tried:
SELECT * from table where date BETWEEN '04-06-15 00:00:00' AND '05-06-15 23:59:59'
But it also output results with a different month, as:
05-07-15 14:52:34
Is there a way to use a single query for solving this issue or I have to change all my database date format?
SELECT *
from table
where
STR_TO_DATE(date,'%d-%m-%Y %T') between
'2015-06-05 00:00:00' and '2015-06-5 23:59:59';
I need to find some records created in a range of quarters. For example, I'm looking for all records created between the 4th quarter of 2008 and the 1st quarter of 2010. I have this in my WHERE-clause:
...and r.record_create_date between to_date('2008 4','YYYY Q')
and to_date('2010 1','YYYY Q')
but Oracle says: ORA-01820: format code cannot appear in date input format. The Q is a valid date format symbol, so I'm not sure what's happened. Is this even a valid way to find values in between calender quarters, or is there a better way?
Also interesting, and possibly related, if I execute this:
select to_date('2009','YYYY') from dual;
The value displayed in my IDE is 2009-08-01. I would have expected 2009-08-04, since today is 2010-08-04.
This:
select to_date('2009 1','YYYY Q') from dual;
of course, fails.
(Oracle 10g)
Oracle says: ORA-01820: format code cannot appear in date input format. The Q is a valid date format symbol, so I'm not sure what's happened.
See the second column of table 2.15 at http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/sql_elements004.htm#i34948. Not all format elements are allowed when converting to dates, timestamps, etc.
I recommend against using between for date range checks. People often will miss values within the ending day that the expect to be included. So I would translate:
and r.record_create_date between to_date('2008 4','YYYY Q')
and to_date('2010 1','YYYY Q')
To
and to_date('2008-10-01', 'YYYY-MM-DD') <= r.record_create_date
and record_create_date < to_date('2010-04-01', 'YYYY-MM-DD') -- < beginning of 2Q2010.
Someone asked the same question on OTN: http://forums.oracle.com/forums/thread.jspa?threadID=1081398&tstart=255
The crux of the issue is that you can not specify "Q" in the TO_DATE function.
Given that you're already specifying a portion of the date, why not provide the entire date? Mind too that to_date('2010 1','YYYY Q') would give you Jan 1st, 2010 when you really want March 31st, 2010... at a second to midnight.
Since the relationship between quarters to months is one-to-many, it doesn't make sense to do TO_DATE('2008 1', 'yyyy q'); what date should be returned? The first of the quarter, the end of the quarter, ...? (On the other hand, converting a date to a quarter - like TO_CHAR(SYSDATE, 'yyyy q') makes sense because a specific date only exists in one quarter.)
So, if you do want a query that looks for a date that falls between two quarters, you will have to "rolll your own" (explicitly stating the dates of the start/end of a quarter.)
As a side note, in case anyone is considering not using TO_DATE please do not use things like: WHERE date_value BETWEEN 'date string1' and 'date string2' without the TO_DATE function. It assumes a default date format and under certain situations can avoid potentially useful indexes altogether.
Below is one example where the same query can have a different result.
select sysdate from dual where sysdate between '1-Jan-10' and '31-Dec-10';
SYSDATE
---------
04-AUG-10
SQL> alter session set nls_date_format = 'YYYY-MM-DD';
Session altered.
SQL> select * from dual where sysdate between '1-Jan-10' and '31-Dec-10';
no rows selected
(Notice that in the second instance no error is returned. It just assumes Jan 10, 0001 and Dec. 10th, 0031.)
I think the best way is to just input the quarter start date and quarter end dates without even bothering with to_date. I think if you use
between '1-Jan-10' and '31-Dec-10'
for example, then you don't (in Oracle I believe) need to_date and it isn't much more difficult than typing in the quarter number
To calculate in Oracle the first day of a quarter and the last day of a quarter from the year and quarter:
I Use the fact
start_month= -2 + 3 * quarter
last_month = 3 * quarter
variable v_year number
variable v_quarter number
exec :v_year :=2017
exec :v_quarter:=4
select :v_year as year,
:v_quarter as quarter,
to_date(:v_year||to_char(-2+3*:v_quarter,'fm00'),'yyyymm') as quarter_start,
last_day(to_date(:v_year||to_char(3*:v_quarter,'fm00')||'01 23:59:59','yyyymmdd hh24:mi:ss')) as quarter_end
from dual a;
YEAR|QUARTER|QUARTER_START |QUARTER_END
2017| 4|2017-10-01 00:00:00|2017-12-31 23:59:59
