Calculating the difference between the two rows of same columns? Example of my Scenario is as follows
I have a table as shown below, there are checks thats has been issued per week (to tell how its been issued per week ,if you see the week number ,there is a change in week no for period of 7 days i.e. what i have to show on my results tables based on week no and probably we may need to take into account for check no too.)
result table and date range i picked up was 1/1/2012-1/31/2012
wekno ! checkno ! end date ! previous period ! Daysin period ------ ! ------ ! ------ ! ------------- ! ------------ 1 ! 1 ! 1/7/2012 ! null (as previous period is 2011 and so prvs year i dont count) ! 7 this because we see change in wkno per 7 days 1 ! 2 ! 1/8/2012 !null becoz this one falls same week and therefore previous peroid would be the same as above ! 7 above reason 1 ! 3 ! 1/9/2012 ! null becoz this one falls same week and therefore previous peroid would be the same as above ! 7 above reason 2 ! 1 ! 1/14/2012 ! 1/7/2012 becoz this a second week as you see the change in wekno and therefore its previosu period is 1/7/2012 ! 7 above reason 2 ! 2 ! 1/15/2012 ! 1/7/2012 becoz this check falls on the same second week so previosu would be 1/7/2012 ! 7 above reason 3 ! 1 ! 1/21/2012 ! 1/14/2012 as a new week no starts this gonn be 1/4/2012 ! 7 above reason
I have two tables tab1 and tab2 with below data Now requirement is to find difference between two table with respect to column "serial_no" which exist only in table tab1 so as per below at serial_no 2 CC4 in tab1 but CC2 in tab2 so this is different how to dump out this data
insert into tab1 values('P1','CC1',101,1); insert into tab1 values('P1','CC4',104,2); insert into tab1 values('P1','CC5',105,3); insert into tab1 values('P1','CC2',102,4); insert into tab1 values('P1','CC3',103,5);
insert into tab2 values('P1','CC1',0,101,102); insert into tab2 values('P1','CC2',101,102,103); insert into tab2 values('P1','CC3',102,103,104); insert into tab2 values('P1','CC4',103,104,105); insert into tab2 values('P1','CC5',104,105,0);
format of dtActivityStartDate/dtActivityFinishDate: 2010-09-17 14:50:51.150 Note: Both dtActivityStartDate/dtActivityFinishDate vcActivityName = Process Request usdFuncTimeCalc (vcActivityName,dtActivityStartDate, dtActivityFinishDate)
i need to calculate time elasped for that type of activity following are the rules:
(If Process Request is the activity) Working Days: Monday through Saturday Hours of Operation: 9AM 5PM
only working hours of day need to the counted like for example if it is sep 15 11 Am is dtActivityStartDate & Sep 17 is dtActivityFinishDate is 10 Am. then time elapsed is 11am to 5pm on sep 15 , 9 to 5 on sep 16 & 9 to 10 on sep 17 so total should be
6+ 8 + 1 = 15 hours + minutes. format of date time: 2010-09-17 14:50:51.150 vcActivityName = Process Request Don't worry about process request..
In my server , already 10g r2 is installated , now am installaling 11r2, during this, at final stage while running root.sh , it will propmt to override 3 files, oraenv,dbhome .. etc under /usr/local/bin in solaris sys, as these files are already owned by 10g owner ,what i have to select (y or n)?
setting up the query/correcting the syntax below so that it calculates the 'number of days difference' between whatever the 'Biggest Date' field value is and whatever the 'current date' is using the 'sysdate'. So far, I've only managed to get the query to calculate the number of days difference (days past due) between the 'need date' and 'estimated delivery date'.
CODESELECT To_Date(need_date, 'YYYYMMDD') Need_Dt, To_Date(Case when estimated_delivery > ' ' THEN estimated_delivery ELSE need_date END, 'YYYYMMDD') Biggest_Date, To_Date(need_date, 'YYYYMMDD') - To_Date(Case when estimated_delivery > ' ' THEN estimated_delivery ELSE need_date END, 'YYYYMMDD') Date_Diff
FROM tableT
WHERE need_date <= (Case when estimated_delivery > ' ' THEN estimated_delivery ELSE need_date END)
Difference in hours is supposed to be 35 but it comes as 34.When i manually find the difference in days and multiply by 24 it comes as 34.999999999 and floor converts it as 34.. But when i execute the difference between dates alone and convert to 24 it shows as 35. So when i apply floor to this, it should be 35 instead of 34 right?
For the following query, difference of the dates in minutes is 2100.. so mod(2100,60) should give 0 but it's giving 60.. Separately if if put mod(2100,60) it is giving as 0 only.
I have one hirarchical query which return the parent to child hirarch level data. it has 11 level child data. i want to create column based on number of child in hirarchy. though i know it is 11 but it can change also.Is there any way i can create the column dynamically
On my APEX page i have region which has sql query as source and it displays as HTML table the query result to the user.
I want to display addinonal column with a hyperlink inside, and that hyperlink would have CGI/URL-parameters which contains the other values of the HTML row.
So, let's say my APEX region queryes columns as "select c1, c2, c3, c4 ..." and displays out values "V1, V2, V3, V4" then i want to have addional output column with such hyperlink:
a href="f?p=100:7:13467554876288::NO::c1,c2,c3,c4:v1,v2,v3,v4">My link column with CGI-parameters</aHow can i create such hyperlink?
The overall idea is that the link would forward to a page which loads those values "v1,v2,v3,v4" into form fields and user can proceed from there.
I'm trying to do a pivot query in oracle to get the years from a column and make a separate column for each. I found an example of the code to use on the internet and i changed it for my own tables but i'm getting errors. Namely a "FROM keyword not where expected" error at the beginning of the 'avg(...' statements.
I have copied the code used in
select stud_id, 2006, 2007, 2008, 2009 from ( select stud_id, avg(case when year=2006 then ((present/poss)*100) else null end) 2006, avg(case when year=2007 then ((present/poss)*100) else null end) 2007, avg(case when year=2008 then ((present/poss)*100) else null end) 2008, avg(case when year=2009 then ((present/poss)*100) else null end) 2009 from attendance.vw_all_attendance_perc group by stud_id );
(1) how can i fill some value in a table column based on some existing column value automatically without user intervention. my actual problem is i have 'expiry date' column and 'status'. the 'status' column should get filled automatically based on the current system date. ex: if expiry date is '25-Apr-2011' and current date is '14-May-2011', then status should be filled as 'EXPIRED'
(2)hOw can i build 'select' query in a report (report 6i) so that it will show me list of items 'EXPIRED' or 'NOT EXPIRED' or both expired and not expired separately in a single report based on user choice. 'EXPIRED' & 'NOT EXPIRED' can be taken from the above question no. 1.
<Column name> value 1 value 2 value 3 . . . value n
Since the column is small it can fit in a page more then one time. I know how to make it print more then once: i switch the repeating frame to print down and across and i modify the frame that contains it so the horizontal elasticity is variable.
After these changes my report looks like this: <Column name> value 1-----------------------value n+1-----------------------value m+1 value 2-----------------------value n+2-----------------------value m+2 value 3-----------------------value n+3-----------------------... .------------------------------- . .------------------------------- . .------------------------------- . value n-----------------------value m
What i want is my report to look like this:
<Column name>-------<Column name>------------<Column name> value 1-----------------------value n+1-----------------------value m+1 value 2-----------------------value n+2-----------------------value m+2 value 3-----------------------value n+3-----------------------... .------------------------------- . .------------------------------- . .------------------------------- . value n-----------------------value m
I have written the code for sql loader, I have given termination of file is | , i have given five columns name in sequence...My Requirement is that i want to mapped 100th column from Csv file after 5th column how to do it.
OPTIONS (ERRORS=100000000) LOAD DATA CHARACTERSET UTF8 INTO TABLE "TARGET_STG_AMC" TRUNCATE [code]....
We are using Oracle 11g with Apex 3.2 on AIX. We are reporting data from customer satisfaction surveys. I'm using the following sql to create my report
<code>select * from( select month,'Overall Satisfaction' as q_group, 1 as srt,Overall Satisfaction,site, case when count(*) < 31 then '*' else round((sum(ttos)/count(*))*100,0)||'/'|round((sum(bfos)/count(*))*100,0)||'/'||count(*) end ospct from v_XXX_report a,(select distinct month_dt month from v_XXX_report) b where Overall_Satisfaction is not null and year_dt = 2012
[Code]....
The problem is that site is not allways present and sometimes I have other variables in addition to site. This creates a situation where the month columns will not allways appear at the same column number. For example, When I run this query as is then the "JAN" column is Col3 (first column is a break, col2 is not shown). When I run this query without site then "JAN" is the second column. I would like to create column links for the "JAN" - "DEC" columns but not for any other columns.
Another issue - in the column link creation screen I can create up to 3 variables that I can pass to the next page. Since my query is a pivot I'm uncertain how to pass the column heading or the row value (for col2)
ie Overall Satisfaction JAN FEB MAR APR MAY ... Overall Satisfaction 12/12/200 12/12/210 12/12/220 12/12/230 12/12/240... Recommend 12/12/200 12/12/210 12/12/220 12/12/230 12/12/240... etc.
So if I clicked on the values at Recommend:FEB how can I get "Recommend" and "FEB" into variables that I can use on the next page? I've tried #column_name#, #month#, #q_name# and #APEX_APPLICATION.G_F10# but no luck.
I want to pass multiple column values of a row in an interactive report page to hidden items in another page through column link. And I did it successfully. However, I found I need to pass more than 3 columns of a row in this report, while a column link only permits me to pass 3 column value at most. Is there anyway that I can pass more column values to hidden items in another page?
I have a table where i have description column which free text column, the data in description column is seperated and i want to corvert 1 row data in multiple rows dependeing on the number of words.
eg
id description 78664 Pumps Alarm from CAMS RTU154
In the above example this column has 5 word so i want data in 5 rows like below
78664 Pumps 78664 Alarm 78664 from 78664 CAMS 78664 RTU154
This column data can be varied from 1 to any number of words.
is there some performance/access difference between a bitmap index on a number column and char(1) column? Both columns are not null with a default value.My application has a querie like this:
If I create a bitmap index on column "column_char", the access plan is not changed. But changing the column datatype to number(1) and obviously the values, the index is accessed and the cost decreases.This table has 4.000.000 rows. Oracle 11.2.0.2SO
Is there a way to alter an existing virtual column to set as a real column without dropping it and recreate (i have index on it, and i don't want to recreate them).
I have a partitioned table with ~50 million rows that was setup with a number(10) instead of a date column. All the data in the table is ALWATS in this format YYYYMMDD
CREATE TABLE T1.monthly ( SEQ_NUM NUMBER(10) NOT NULL, DAY_DK NUMBER(10) NOT NULL ) TABLESPACE USERS PCTUSED 0 PCTFREE 10 [code]........
When I use the exchange partition method the parition is able to move the data from "monthly" table to "mth" table.
desc t1.mth; ### my temorary table Name Null? Type ----------------------------------------- -------- ---------------------------- SEQ_NUM NUMBER(10) DAY_DK NUMBER(10)
Than when I try to alter my temp table "mth". I get an error table must be empty to change column types.
alter table n546830.mth modify (DAY_DK date);
Next I tried making my temporary table "mth" a date column. When I an the exchange partition command I get the following error:
alter table t1.monthly exchange partition DEC_2012 with table t1.mth without validation; alter table n546830.monthly exchange partition DEC_2012 with table n546830.mth without validation * ERROR at line 1: ORA-14097: column type or size mismatch in ALTER TABLE EXCHANGE PARTITION
Method I can use to convert a number(10) to date column and keep the information in a table. Note, I don't care about HH:MM:SS as I never had that information to begin with and would be happy to set that part of the date column to all zeroes "00:00:00"
