PL/SQL :: How To Sum Times Value
Mar 18, 2013I'm using Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - ProdMy problem is, There is data for IN time and OUT time data type is DATE. I need to calculate OT hour from this two field and store into a third one column. But i'm confuse what should be the data type of the third column. Is it number or else ?
I know difference of two date column is number. So, first i need to know that data type i should use ?
Secondly, how i get the sum of the all stored time ? for example data are
1.30 -- One hour and thirty min.
2.45
3.50
SQL & PL/SQL :: How Many Times Do The Inner Execute
Oct 2, 2010I found this query in one of my stored procedures that updates a key for a value in a data table by reading the information from a master table.
The data table is: ITEM_INVENTORY
The master table is: MASTER_SOURCE_SYSTEM
UPDATE ITEM_INVENTORY I
SET I.SOURCE_SYSTEM_ID =
(SELECT NVL(M.SRC_SYS_ID,-100)
FROM MASTER_SOURCE_SYSTEM M
WHERE M.SRC_SYS_DESC(+) = I.SOURCE_SYSTEM_CODE )
WHERE ORG_CODE = 'TNXC'
AND EXISTS (SELECT 1 FROM MASTER_SOURCE_SYSTEM M
WHERE M.SRC_SYS_DESC(+) = I.SOURCE_SYSTEM_CODE )
The situation here is that:
1. There are about 15000 rows that match ORG_CODE = 'TNXC'.
2. The SOURCE_SYSTEM_CODE is same for all the 15000 rows and there is a matching entry for it in the MASTER_SOURCE_SYSTEM table.
My question is: Do both the inner select statements execute 15000 times?
The statement executes within a second and updates 15000 rows. How is this made possible?
SQL & PL/SQL :: How To Get Rows N Times In A Result Set
Mar 9, 2010How to get rows N times in a result set?
For obscure test purposes I need to modify an existing SQL query to emit the rows N times instead once. I'm aware of the possibility to "UNION ALL" the query with itself to get the all rows twice.
But as I require the resulting rows to be emitted around ten to hundred times this approach doesn't seem sensible to me. Not to speak of the missing possibility to parametrize the number of "repetitions".
SQL & PL/SQL :: Dealing With Times Recorded In UTC
Oct 8, 2011I am dealing with a bunch of tables containing sales information for an New Zealand organisation. The sale datetime has been recorded as UTC.
New Zealand operates Daylight Savings, so twice a year it changes its clocks.
When New Zealand is on standard time it is UTC+12.
When New Zealand is on daylight savings time it is UTC+13.
Thus an event which actually occurred when New Zealand was on standard time at 2011-08-31 15:20:52 local time, is recorded in the database as having occurred at 2011-08-31 03:20:52. However, an event that actually occurred when New Zealand was on daylight savings time at 2011-10-06 15:20:52 local time, is recorded in the database as having occurred at 2011-10-06 02:20:52.
I want to be able to read the sales dates from my table and convert them to the actual time in New Zealand when the event occurred. The table will contain data for sales that occurred in both standard and daylight savings times.
I do not think that the data has been stored with time zone information, simply that the application writing the data to the Oracle database, calculated the event time as UTC when it occurred and wrote that time to the table.
Does Oracle only know about what UTC-offset is in force right now or is it capable of determining what offset from UTC is required for any given historical date ?
How To Make A Command Loop Three Times
Jun 28, 2013I have code that creates a sequence and a select statement that generates the next number in a sequence. It starts the sequence at 5 and every subsequent number is the previous number minus 3. The minimum value it can go to is 0. All I want is for my select statement to execute three times in a row. Is there any way I can do that?
create sequence MY_FIRST_SEQ
increment by -3
maxvalue 5
start with 5
minvalue 0
nocycle;
select MY_FIRST_SEQ.NEXTVAL from dual;
Generate Last Seven Days Batch Run Times
Jan 8, 2013I would the query to do the following:
1. Make the jobname distinct, because it keeps giving me multiple entries for each jobname
2. Add the the start_time of SOD_start_data9_UAT1 to end_time fodba_MUAT1 to get the combined duration
3. CONCAT jobnames SOD_start_data9_UAT1 and end_time fodba_MUAT1
4. Generate the last seven days batch run times
5. Generate a report into .csv format and email out
6. I have access to sqlplus and plsql developer
select distinct JOBNAME, schedtab
, to_char(to_timestamp(trim(timestmp)
, 'YYYYMMDDHH24MISS') - numtodsinterval(elaptime / 100
, 'SECOND'), 'YYYY-MM-DD HH24:MI:SS') as start_time

SQL & PL/SQL :: Determine Number Of Times A Value Appears
Nov 11, 2012I am trying to determine the number of times a value appears and display the count. However the value can only be counted once per 'trip' even though it may appear several times per trip.
for e.g.
Quote:trip table
-------
trip_id start_date end_date duration
445 01-jan-12 03-jan-12 3
Quote:pickup table
--------
pickup_id trip_id company
1 445 randomname
2 445 randomname
3 445 google.inc
4 878 randomname
with the above data the expected value would be two because the trip id appears twice so it was just the one trip - given a count of one. I am not sure how create a query to check this.
SQL & PL/SQL :: Populate Column Two Times With Different Criteria?

PL/SQL :: Dates And Times In A Subquery With A Group By
Dec 20, 2012I have some data that I need to group to the Month, Day, Year, Hour and minute in a subquery. Then I need to summarize it to the Month and year in the parent query.If I try to group by the field itself, it is not taking it down to hour and minutes - just the day, so I am losing records.if I do a TO_char (visitdate, 'DD-MON-YY HH:MI AM') in the subquery, then the main query no longer sees it as a date, so cannot do my TO_CHAR(VISITDATE,'MON-YYYY') in the parent. I could parse out the pieces using string manipulation, but that seems rather silly.Is there a way to keep as a date in my sub query and then convert to a string?
it looks a little like this, with some other fields that I have to max, sum ...
visit provider person visitdate
1 2 1 12/20/2012 10:30
2 2 2 12/20/2012 10:30
3 2 5 12/20/2012 11:30
4 3 3 12/21/2012 11:30
5 3 4 12/21/2012 11:30
I need to boil this down to
provider visitdate
2 12/20/2012 10:30
3 12/21/2012 11:30
2 12/20/2012 11:30
Then I use that in a subquery where I use just the month and year TO_CHAR(VISITDATE,'MON-YYYY') AS APPT_MO_YR right now if I do a group by visitdate on the subquery it returns
provider visitdate
2 12/20/2012
3 12/21/2012
even if I do a group by to_date(visitdate, 'DD-MON-YY HH:MI AM') it is still returning :
provider visitdate
2 12/20/2012
3 12/21/2012

View 3 Replies View RelatedPL/SQL :: Sample Function Returns Many Times Of Expected Value
Nov 30, 2012The SAMPLE clause in the select statement works well in most cases, but we found in some instances the result is way off - between 200% to 700% discrepancy has been observed.
For example, we have thee tables with the following results:
Table1: 495,365,317 rows (20 cols, unique primary key present), SAMPLE ( 0.002018712182064212 ) returns 41,499 (about four times off - we expected about 10,000)
Table2: 3,350,864,539 rows ( 5 cols, unique primary key present), SAMPLE ( 0.00029843044634040336 ) returns 9,835 (this is good as it is close to 10,000)
Table3: 6,974,724,543 rows ( 5 cols, no unique primary key present), SAMPLE ( 0.00014337483779250091 ) returns 58,789 (about six times off - we expected about 10,000)
The tables got billions of rows, and that is why we want to do sampling. The sample percentage rate is computed to return about 10,000 rows in all three tables.On Table3, we ran the sampling three times in one occasion, and we got "58,570", "24,575" and "24,561"
I expected +/- 20% of variance, but 200% to 700% seems to be way too much.Once again, I stress that it does work well in most cases (another 3.4 billion table and numerous smaller tables we tested were well within +/- 5 percent of the target).I noted the presence of a primary key above because I read an article saying that the SAMPLE function relies on the existence of a primary key (which does not quite explain the examples above).Is this kind of spread something we should expect or is it a bug? Is the sampling rate too small for such large tables?
Forms :: FRM-40209 - Field Must Be Of Form XX-XX-XXX Coming Several Times
Oct 3, 2012I have a form which has a Number field. I set it's Format Mask property to 9,99,99,99,99,999 so that I can format it comma separated and to restrict the user to enter decimal values. If the user enter any format other than this for example any decimal values, it is showing the message FRM-40209:Field must be of the form 9,99,99,99,99,999 which is fine. But when the user enters a decimal value and try to save the form it pop up this message several times.
I tried to catch this error in ON-ERROR trigger and display a message. But this is also pop up several times. I tried to raise form_trigger_failure also. This is also not working. I want this error message to come only once.

SQL & PL/SQL :: Difference Of Dates And Get Minutes
Oct 25, 2012 I have a date in_sdate as In parameter defaulted to sysdate. Basing on this in_Sdate I calculate my start and end dates as:
v_sdate TRUNC (in_sdate, 'MI') - 15 / 1440 ;
v_edate := TRUNC (in_sdate, 'MI');
My procedure is run for every 15 minutes. Now suppose if I am running for old dat, then I should get the difference of dates by taking
v_old_Date := v_edate - in_Sdate;
Divide this by 15 , round that value and loop to run the procedure for that n times. My doubt is when I am saying
v_old_date := v_edate - in_sdate ; I am getting expression is of wrong type. How can I take the difference of the dates and get the minutes from that ?

SQL & PL/SQL :: Carriage Return Line Feed Multiple Times In Same CLOB

insert into table(Data) values (MyConc)
(MyConc is a string put togheter by another application)
Because of this I can't use the "|| chr(13) || chr(10) ||" because I only have that one concatinated string.Is there a character I can set in my string that automatically translates to a CRLF?
My CLOB-data should look something like this:
1;blue;Woodstock;;
34;giant;squid;attack;
5;blue;squid;;
And in this case the "MyConc" would look like this "1;blue;Woodstock;;[X]34;giant;squid;attack;[X]5;blue;squid;;[X]
where [X]=the character I need for CRLF =)
