I have time fields that have been converted from a 12hr clock to a 24hr clock and these fields hold only the time...no date.
I need to be able to determine the difference between column A and B eg.
Column A: Column B: 11:00 14:00
I can remove the ':' by using the replace command, but as I need to run on a actual 24hr clock I am not sure how to tackle the calculation as it is not the full oracle datetime format.
SELECT FROM_TZ(CAST(TO_DATE('1999-12-01 11:00:00', 'YYYY-MM-DD HH:MI:SS') AS TIMESTAMP), 'gmt') AT TIME ZONE '+05:30' "Time at Time zone" FROM DUAL;
Time at Time zone 01-DEC-99 04.30.00.000000 PM +05:30
My requirement is that
I want to add 2 hours to DateTime i get here i.e. add two hours in result and display the resultant date and tine in time zone '+05:30'. I also want to check that the resultant time falls in business hours (9 am to 6 pm).
Currently I am working on payroll system where I have to calculate employees working hours/late coming hours/early going hours against its roster which is defined in the beginning of every month/week.
In roster form user define shift of every employee like
Code Name Shift 7 Saad Nafees A - 09:00 17:00 492 Muhammad Nasir Shahzad B - 17:00 01:00 243 Muhammad Tahir C - 01:00 09:00
Roster table structure
code varchar2 name varchar2 Shift date Remarks varchar2
shift table structure
code varchar2 timein date timeout date latetime date Hdaytime date
Oracle stores both date and time information in date data type, suppose today user change shift timings from 17:00 to 17:30 or user change timein/timeout in attendance form then oracle will store current date with user define timings.
Now this is the main problem which I am facing because whenever you calculate difference between timein and timeout or compare with its roster then output comes wrong because oracle returns total no of hours whenever you minus two dates.
elapsed time = time spent on waits + time CPU was used
Total time during snaps = Elapsed time + (may be) time waited for CPU...In AWR is it possible to draw such equation? I can see that the AWR report has following elements
1) End Snap time - Begin Snap time 2) DB time - as mentioned at the top of AWR report 3) DB CPU - in "Top 5 Timed Foreground Events" (I assume this is 'CPU used by sesson timing' in statspack) 4) Total of time for all Statistics in "Time Model Statistics" 5) BUSY_TIME + IDLE_TIME - "Operating System Statistics"
Time between 2 snapshots? or what else? Also for which seconds to multiply to 'DB Time(s)' per second and 'DB CPU(s)' per second in Load Profile to get the db time and CPU time?
(both these fields a_std and a_time are coming as varchar from the parent table in a cursor.(basically they are time period and actual arrival time respectively)
i was juggling with the attempt to make varchar to timestamp or date..but caught with Round up /Round down)
Formula ->
A = Round down [A_TIME - A_STD] B = Round up [A_TIME) - 10 minute + A_STD]
where
A_TIME VARCHAR2(8) N Time (Format" HH:MM AM/PM") eg "3:50 PM" A_STD VARCHAR2(5) N Standard time (Format" HH:MM") eg "1:00"
Allowed values for A & B after round up/down = multiple of 10 ( 11:00,11:10,11:20 etc.)
When I try to extract the date tag value from XML data, the time stored in 20120602153021 format i.e., YYYYMMDD24HHMISS format. The following statement extracts only date as 02-JUN-12 however do not extract the time part.
If I try the same in SQLplus with to_date it works however fails in PL/SQL.
XML data: <?xml version="1.0"?> <RECORD> <REGTIMESTAMP>20120601130010</REGTIMESTAMP> </RECORD>
PL/SQL Extract:
CURSOR c_xml_record IS SELECT extract(value(d), '//ACTIVATIONTS/text()').getStringVal() AS REGTIMESTAMP, FROM t_xml_data x, [code].......
I want to reset my date to this format: 12/31/2012 11:59:59 PM - see code below:
DECLARE v_latest_close DATE; BEGIN v_latest_close := TO_DATE ('12/31/2012 23:59:59 ','MM/DD/YYYY HH24:MI:SS'); DBMS_OUTPUT.PUT_LINE('The new date format is : '|| v_latest_close); END;
the code above displays only : 12/31/2012 instead of 12/31/2012 11:59:59 PM
I am having problems with the XMLTable function. I cant get it to see the entire date/time value in a date field. This wont work
select x1.* from XMLTABLE('/DOCUMENT' passing xmltype('<DOCUMENT><STR>abc def ghi</STR><NUM>1234</NUM><DT>2013-02-17T04:24:02</DT></DOCUMENT>') columns STR varchar2(25), NUM number, DT date) x1;
However if I change the DT tag to just the date only "2013-02-17" it works. Why wont Oracle see the entire date/time format even if its ISO 8601 compliant?
is there possible to retrieve date with its time in oracle ,if we didnot provide time while insertion? like hiredate column of emp table can we get hiredate of each emp with its time of joining. i am using "11g Enterprise Edition Release 11.2.0.1.0"
I have a question with Oracle sql developer, i've installed oracle 11g express edition, and i want to insert values 'date' and 'time', but i only got the resultat like this:
Who can tell me how can i do to show just date info in 'date' and same for the 'time'?
I am converting data from an old paradox table to a new oracle table, one of the problems im having is incompatibility with date and time formats:
some columns contain times in the format : "00:00:00" eg..... "15:00:00" some columns have date in the format: "dd/mm/yyyy" eg....... "21/08/2000" some columns have time and date eg.. "05/09/2000 15:49:39"
Currently I have the data held in tables within an access database, and in CSV format.
eg, I have dates like 03/04/2010 which i need to be 03-APR-10....
how I can get the following into Oracle date formats? there is over 1000 records so manual conversion is out of the question
SQL> desc guide; Name Null? Type ----------------------------------------- -------- ---------- GUIDE_ID NOT NULL NUMBER(20) CHANNEL_ID NOT NULL NUMBER(5) SHOW_DATETIME DATE [code]....
when I run this query it only displays the date but no time.how to display it with the date and time?
I have a sql id,I want to figure out how many number of times that sql was executed since last 30 days.I can get some details from dba_hist_active_sess_history.
But how to get count(total executions in one day )like wise for 30 days or so.and How can i map SNAP_ID to date&time .
I have a table test and it contains date datatype column JDATE;
SQL> desc test Name Null?

like for 1/11/2010 4:17:29 PM It would be like 1/11/2010 4:18:29 PM. for 1/11/2010 4:15:47 PM it would be like 1/11/2010 4:16:47 PM.Can we do this...
select TO_DATE( TO_CHAR(CAST((B.EOAWDTTM_MODIFIED) AS TIMESTAMP),'YYYY-MM-DD-HH24.MI.SS.FF'),'YYYY-MM-DD') from PS_SR_EX_ER_AW_VW B where rownum < 5
and It gives me the error
ORA-01830: date format picture ends before converting entire input string 01830. 00000 - "date format picture ends before converting entire input string"
When I select sysdate from dual it shows me the time in EST. But when I try to fetch the time from a column which is being updated almost every minute with sysdate of the time it is being updated, it shows me the time in UTC that is 4 hours added to the time when it was logged.

I am using the same query on a different table and there's no problem on it:
select to_char(ENTRYDATE,'MM-DD-YYYY HH24:MI:SS') from TBL_XX_PROGRAM where ENTRYDATE > sysdate -10 and rownum <10 03-03-2011 17:06:48 03-03-2011 17:06:48 03-03-2011 16:59:08 03-03-2011 16:59:08 03-03-2011 12:04:21
I checked the DDL of both tables and the only difference is that the TBL_XX_PROGRAM have the ENTRYDATE field defined as not null and the ENTRYDATE on the TBL_BANDWIDTH_READS does not have the same constraint, could it affect?
Is there a way I can find what the last date/time and index was used for a select...
I have a table with several indexes on them, which I beleive are not being accessed.
I use the following the query to find indexes that where not accessed in a while but this I believe is limited my my workload repository retention, which is set to 90 days.
select index_name from dba_indexes where table_name='<table name>' and index_name not in (select c1 from( select p.object_name c1, p.operation c2, p.options c3, count(1) c4 from dba_hist_sql_plan p, dba_hist_sqlstat s where p.object_owner = 'MTAS' and p.operation like '%INDEX%' and p.sql_id = s.sql_id group by p.object_name, p.operation, p.options order by 1,2,3))
Without increasing my repository retention is there a way I can get the last date/time, which an index was used instead of just saying it has not been used in 90 days (retention setting). Is this information kept in the SQL plan?
I have a csv file where a field has values like "Fri Aug 2 19:22:02 EDT 2013". through unix i am able to place the value into an unix variable but the problem is this should be inserted into a date column in my database table. Basically, the relevant data to be extracted is "Aug 2 2013 19:22:02" and then i need to insert the same into my database column. And the date column in the table should displays like '08/02/2013 19:22:02'.
