I am working on an application that allows a user to create a KPI formula, and the app dynamically creates a view for this formula. However as we started using it we have found that we are encountering the ORA-10476 (divisor is equal to zero) often. I have read about options of using decode or case to prevent this but it doesn't cover all our options. As a result of the fact that the user can create any equation he wants , and it can be as complicated as they want ( 2 examples:
A/(B/C-D/E) - If C or E or (B/C-D/E) are 0 the whole select will fall
A/(B-C/(D-F)) - if (D-F) or ((B-C/(D-F)) is 0 then again the select will fall.
I have seen that in MS SQL they have an option of arithabort which allows the database to return the rows that don't fall under the "divisor by 0".
either by setting something similar to arithabort, or maybe a procedure to check an equation and return the arithmetical steps in order that athey are performed?
The below code gives me error (ORA-01476: divisor is equal to zero)
SELECT ((COUNT(DECODE(SUBSTR(A.ASSETNUM,6,3),'ACS','ACS',0,null))/COUNT(DECODE(SUBSTR(A.PMNUM,1,3),'ACS','ACS',0,null)))*100) FROM WORKORDER A WHERE TO_CHAR(A.REPORTDATE,'MON-YYYY') = :WO_DATE;
I would like to select test_sub.price as per the below conditions. If test_bb.value_date, test_bb.vehicle matches to test_sub.value_date,test_sub.vehicle then display test_sub.price
If there is no match then as above find the closest test_sub.value_date which is less than test_bb.value_date and select corresponding test_sub.price for the same vehicle combination.
begin insert into test_bb values(10,to_date('12-04-2012','dd-mm-yyyy')); insert into test_bb values(10,to_date('10-02-2010','dd-mm-yyyy')); insert into test_bb values(20,to_date('24-01-2014','dd-mm-yyyy')); insert into test_bb values(20,to_date('22-02-2008','dd-mm-yyyy')); end; /
begin insert into test_sub values(10,to_date('12-04-2012','dd-mm-yyyy'),2); insert into test_sub values(10,to_date('08-01-2010','dd-mm-yyyy'),4); insert into test_sub values(10,to_date('14-04-2014','dd-mm-yyyy'),6); insert into test_sub values(10,to_date('06-08-1947','dd-mm-yyyy'),8); insert into test_sub values(20,to_date('24-01-2014','dd-mm-yyyy'),10); insert into test_sub values(20,to_date('20-02-2006','dd-mm-yyyy'),12); insert into test_sub values(20,to_date('18-02-2004','dd-mm-yyyy'),14); insert into test_sub values(20,to_date('28-02-2006','dd-mm-yyyy'),16); insert into test_sub values(20,to_date('22-DEC-2007','dd-mm-yyyy'),19); end; /
I could write as below but I would like to know if there is a better way of doing it.
select bb.vehicle ,sub.price ,bb.value_date from test_bb bb ,test_sub sub where bb.vehicle=sub.vehicle [code].........
im trying to create a trigger that, when i insert a new song in the songs table, it will check the category of the song (song_cat) and increase the respective cat_total (from table categories) by 1.
here is what i've done so far:
drop trigger countcat; CREATE TRIGGER countcat AFTER INSERT ON songs FOR EACH ROW update categories SET cat_total= cat_total +1 WHERE cat_name = (select song_cat FROM inserted);
What to write in the cat_name = (select ...). I have tried lots of stuff but still nothing. when i use this, i get the error that mydatabase.inserted doesnt exist
I have set up a view that pulls news & events records.
SELECTc.priority, c.startDate, p.headline, p.newsID, p.kicker, p.category, p.webPath, p.makePopup, p.thumbnail, p.shortDesc, p.storyType FROM(so_news p LEFT OUTER JOIN so_news_deptLevel c ON p.newsID = c.newsID) LEFT OUTER JOIN so_departments d ON d.deptID = c.deptID
[Code].....
For events I want only the events that have a p.startDate equal to today. I have tried setting that line up a few different ways.
p.startDate = sysDate didn't provide any records for events p.startDate = TO_CHAR(sysDate, 'MM/DD/YYYY') freaked the system out and nothing appeared for either parts of the union
I'm trying to write a query that counts how many sessions are active during a 1 second time interval, then returns the maximum number of sessions active during any time interval, and all the time intervals that hit that max.
I've created a query so I can easily compare two sets of data for two different instruments:
select a.CalId, a.AtName, a.NRef, a.VaLoat, a.ValTime, a.ValRing, cvs.NRef, cvs.CalId, cvs.AtName, cvs.VaLoat, cvs.Valtime, cvs.ValRing from CalcAttribute a, CalcAttribute cvs where a.NRef like '438815' and cvs.NRef like '438813' and a.CalId *= cvs.CalId and a.AtName *= cvs.AtName union
[Code]...
This works great - however I want to add an addtional condition, basically so it only returns where the two are not equal.
I thought I should just be able to add an extra: and a.ValLoat *<> cvs.ValLoat and a.ValLoat <>* cvs.ValLoat
But it doesnt seem to like this (Incorrect syntax near '<'.)
ADD_REWARD_sp. Given the identifier of a project, add a new reward for the project. The procedure should return a unique identifier for the reward. The month and year indicated should be greater than or equal to the current month, or an error message should be generated. The pledge amount should be greater than zero. The number of backers, if not NULL, should be greater than 1. If the project is not found, generate an error message.
This is the procedure head:
create or replace PROCEDURE ADD_REWARD_sp( p_proj_id IN NUMBER, p_pledgeAmt IN NUMBER, p_rewardDesc IN VARCHAR2,
[code]...
Basically, what I am struggling with is how to check if th month and year is greater than or equal to current month. I suppose it would be easy with just checking SYSDATE, but in this case I need to use both month and year.
, I'd like to create a constraint (when creating a table) that checks to ensure that the 'Year' entered is less than or equal to the current year (based off SYSDATE). Per the code below, I keep getting the same error, "missing right parenthesis". I've spent more than an hour trying different ways to get this to work, but I've been failing miserably. I am using Oracle 11g Express.
CREATE TABLE TEST (Name VARCHAR2(7) PRIMARY KEY, Year NUMBER(4), CONSTRAINT TEST_YEAR_CK CHECK (Year <= (TO_NUMBER(TO_CHAR(SYSDATE, 'YYYY')))FROM DUAL); *ERROR at line 4:ORA-00907: missing right parenthesis
