I need to restrict a query with a
SELECT ... FROM ...
WHERE my_date=(RESULT FROM A SELECT)
... ;
in order to achieve that I am using as result of the select a timestamp (if I instead use a datetime I get nothing from my select probably because the format I am using trims the datetime at the second).
Sadly this is not working because these kindo of queries:
select DISTINCT TO_DATE(TO_TIMESTAMP(TO_DATE('25-10-2017 00:00', 'dd-MM-yyyy HH24:MI'))) from DUAL;
return an
ORA-01830: date format picture ends before converting entire input string
how to deal with timestamp to date conversion?
If you want to just compare and check only he dates use trunc on both LHS and RHS.
SELECT ... FROM ...
WHERE trunc(my_date)=(select trunc(RESULT) FROM A)
... ;
This will just compare the dates by truncating the timestamp values
You can use the combination of "TRUNC" and "IN" keywords in your query to achieve what you are expecting. Please check the below query sample as a reference.
SELECT * FROM customer WHERE TRUNC(last_update_dt) IN (select DISTINCT (TRUNC(last_update_dt)) from ... )
Cheers !!

How do you convert a string type like
t1.updte_timestamp
2018-06-02-08.18.45.562742
2018-05-26-09.18.16.594824
into a timestamp? SHOULD RESULT IN:
2018-06-02-08.18.45
2018-05-26-09.18.16
ETC
The values had been imported from excel and are in STRING-TYPE
I tried:
SELECT
to_timestamp(cast (t1.updte_timestamp as string), 'yyyy-mm-dd hh:mm:ss') as updted_timestamp FROM OLD;
but results in NULL for all values
thank you
you can substr your string and apply to_timestamp as follow
select to_timestamp(substr('2018-06-02-08.18.45.562742', 1, 19) , 'yyyy-MM-dd-HH.mm.ss');
Make sure you use MM for month and HH for hour in upper case
I have a date table in my db in Oracle. When I run a query I get the date format as '01-05-2015' but when I run a similar query in BIRT, I get the date format as '01-MAY-2015 12:00 AM'. How can I get the date format in dd/mm/yyy by keeping the data type of date field as date.
here is sample of my database.
EQ_DT
05-07-2015
06-06-2015
15-02-2015
19-09-2015
28-12-2015
also my query is :
select to_date(to_char(to_date(enquiry_dt,'DD/MM/YYYY'),'DD/MM/YY'),'DD/MM/YY') as q from xxcus.XXACL_SALES_ENQ_DATAMART where to_date(to_char(to_date(enquiry_dt,'DD/MM/YY'),'DD/MM/YY'),'DD/MM/YY')>'21-06-2012' order by q
I am getting error of NOT A VALID Month also
If enquiry_dt is already a date column, why are you trying to convert it to date (and then to char and to date again)?
SELECT to_char(enquiry_dt, 'DD/MM/YYYY') AS q
FROM xxcus.xxacl_sales_enq_datamart
WHERE enquiry_dt > to_date('21-06-2012', 'dd-mm-yyyy')
ORDER BY enquiry_dt
In birt, where you place the field on the report, set the field type to date. Then in properties for that field , go to format date time, and finally specify the date formatting you want for that field .
I prefer to always use pass date parameters as strings to BIRT, using a known date format. This is for report parameters as well as for DataSet parameters.
Then, inside the query, I convert to date like this:
with params as
( select to_date(pi_start_date_str, 'DD.MM.YYYY') as start_date_incl,
to_date(pi_end_date_str, 'DD.MM.YYYY') + 1 as end_date_excl
from dual
)
select whatever
from my_table, params
where ( my_table.event_date >= params.start_date_incl
and
my_table.end_date < params.start_date_excl
)
This works independent of the time of day.
This way, e.g. to select all events for january 2016, I could pass the query parameters '01.01.2016' and '31.01.2016' (I'm using german date format here).
I'm trying to retrieve the max datetime of a task started, grouping by task_code.
I've tried the following query to get all the max date, but the date and time are two different fields, if I try to concatened like,
MAX(DATEINI||' '||HOURINI)
to get the latest datetime by group, the query return empty. Is possible to do this, am I missing something?
SELECT DATEINI||' '||HOURINI AS STARTED, TASK, TASK_CODE
FROM TB_TASKS WHERE DATEINI IN
(SELECT MAX(DATEINI) FROM TB_TASKS GROUP BY TASK_CODE)
ORDER BY DATEINI DESC, HOURINI DESC;
Try working with dates instead of strings like this:
SELECT DATEINI||' '||HOURINI AS STARTED, TASK, TASK_CODE
FROM TB_TASKS WHERE TO_DATE(DATEINI||' '||HOURINI,'DD/MM/YYYY HH:MI:SS') IN
(SELECT MAX(TO_DATE(DATEINI||' '||HOURINI,'DD/MM/YYYY HH:MI:SS')) FROM TB_TASKS GROUP BY TASK_CODE)
ORDER BY DATEINI DESC, HOURINI DESC;
Check that to_date format depends of your context.
My code in the stored procedure:
SELECT * FROM
my_table ir
WHERE
--where clause goes here
ORDER BY
CASE WHEN p_order_by_field='Id' AND p_sort_order='ASC' THEN IR.ID end,
CASE WHEN p_order_by_field='Id' AND p_sort_order='DESC' THEN IR.ID end DESC,
CASE WHEN p_order_by_field='Date' AND p_sort_order='ASC' THEN TO_CHAR(IR.IDATE, 'MM/dd/yyyy') end,
CASE WHEN p_order_by_field='Date' AND p_sort_order='DESC' THEN TO_CHAR(IR.IDATE, 'MM/dd/yyyy') end DESC;
Problem is that sorting is done based on the char, which comes out wrong for the date case. CASE statement, however, won't allow any other datatype other than char. So what is the solution in this case? I need to be able to pass the p_order_by_field into the stored procedure.
Thanks
Should be simple - just use ISO date format in your case:
TO_CHAR(IR.IDATE, 'yyyy-mm-dd')
and you should be fine.
Another problem could occure when you want to sort on the date difference (let say number of days between two days).
For example such a sort would return number 13 (days) before 9 (days).
The solution is that you concatenate length of date difference and the difference itself:
length(trunc(date2) - trunc(date1)) || to_char(date2 - date1)
Using SSRS with an Oracle Database. I need to prompt the user when running the report to enter a date for report. What is the best way to add in the parameter in my SSRS Report. Having problem finding the right date format. under the "Report Parameter" menu, I have setup the Report Parameters using the DateTime Datatype.
Keep getting this error "ORA-01843: Not a Valid Month"
Thank you for your help.

You use CAST(a.S_Date AS DATE) in your query, where a.S_Date is a VARCHAR: To_CHAR(ITH_F.Start_Time, 'MM/DD/YYYY'). If your session date parameter NLS_DATE_FORMAT is different from 'MM/DD/YYYY', this will result in a format error (in your case I suspect your NLS_DATE_FORMAT is something like DD-MON-YYYY, resulting in a "month" error).
A few options:
don't use TO_CHAR in the inner query (always try to keep the date format for internal calculations, use TO_CHAR only where it belongs -- in the GUI). If you only want the date portion, use TRUNC.
use TO_DATE instead of CAST in the outer query: to_date(a.S_Date, 'MM/DD/YYYY'), this is obviously tedious: you cast a date to a varchar that is later transformed to a date.
