Divide by ZERO error.

Hello
I need a little help. I get divsor is equal to 0 error on the two 6i devloper and oracle pl/sql report writer
In the report designer, I have a column of formulas with the following:

Return ((:-: / b): a) * 100;

What is a simple way around the divide by 0 error?
Thank you.

Make sure that: a is always greater than 0, otherwise do not run the formula.

if :a > 0
then
   return ((:a - :b)/:a) *100;
else
   return 0; -- or whatever you want
end if;

Error: arithmetic over / underflow - divided by zero?

Hello
IM newbie on Adobe LiveCycle. Ive was able to create a form and now I tried to make some calculation about it.
All right, the pdf is the calculation, but Im getting an error, because I understand that I'm trying to calculate with the classified, those that are empty - no need to register again as a field of zero = > divide by zero...?
Can someone please help me, how to write the formula to get no errors?
My actual formula is:
pod11. RawValue = (((pod2.rawValue * (pod8.rawValue / 100)) - pod6.rawValue) / pod2.rawValue) * 100
Thank you very much for the help!

Hello

to avoid errors to the breast to calculate that each field to ensure there is no rawValue is equal to null, you need to check...

If you use formcalc, use "<>" or "no" to specify not equal to

If you do not use javascript, use «!» = « ou » ! ==' to specify not equal to

JavaScript

If (pod2.rawValue! = null & pod8.rawValue! = null & pod6.rawValue! = null) {}

pod11. RawValue = (((pod2.rawValue * (pod8.rawValue / 100)) - pod6.rawValue) / pod2.rawValue) * 100;

} else {}

pod11. RawValue = null;

}

FormCalc

If (pod2.rawValue <> null & pod8.rawValue <> null & pod6.rawValue <> null) then

pod11. RawValue = (((pod2.rawValue * (pod8.rawValue / 100)) - pod6.rawValue) / pod2.rawValue) * 100

on the other

pod11. RawValue = null

endif

Handful of division by zero error in SQL
Hello

a few messages back, someone asked about how best to manage divide them by zero.

Can I come back to this topic with, what is the best way to manage divide them by error in SQL without repeating the code...

What I have in mind is often divided by error appears as the result of a long formula calculation - and trying to bury a long a long calculation formula in a case statement gives you an extremely long result, but is not ideal for the maintenance of the code.

Encapsulating the manipulation in a function is not great for performance reasons.

So is there a simple way to do the equivalent of (pseudo)

Select IFerr (real / (RidiculouslyLongConvulutedFormulaHereWhichSometimesYieldsZeroValues), 0) of the double

Where IFerr works as NVL - except that it gives 0 when the result is a wrong number or the result otherwise?

Thank you

Robert.
Hello

a few messages back, someone asked about how best to manage divide them by zero.

I saw this thread, but it mentions the NULLIF function?

You can apply it to each denominator in your formula, so it returns NULL in which case it is set to 0.

For example,.
```
with t as (
 select 1 numerator,
        0 denominator
 from dual
)
select numerator/nullif(denominator,0) as div
from t;
```

'Division by zero' errors are triggered by the application, not by Windows. You must ask the supplier for advice.

Division by zero error.

Hi all
I get division by zero error in one of the reports that has been developed by one of our programmers. I think that this can be easily corrected in decoding or using a Case statement. I'm not sure how to use it below scenario.

Just a hunch, but the version of your database includes analytical functions?

You try to do the following?

(1) if spread_miles_total is set to NULL, use instead 1.
(2) if spread_miles_total is not null and is equal to 0, then use 1.
(3) if spread_miles_total is not null and is equal to 0, then retains its value.

If so, then use the CASE expression as follows-

Divide by zero problem

Why n %3 or n MOD 3 return "Division by zero is not allowed.", if n == 0? (3 may be a number any).
Using CF 9,0,1,274733
Doug

Used with numeric values actual/double modulo operator doesn't make much sense from a point of view of math in the first place because it is really intended to provide you with the remainder after integer division.

ColdFusion still allows you to do this, but if the right hand side of the operator modulo is a numeric value real/dobule it will simply ignore the fractional part. In your case, it will be 3 MOD 0-> so division by zero error.

This particular behavior is actually documented in the CF documentation as such.

Example 11-5 Bulk Operation That Continues Despite Exceptions

The following example shows how you can perform a number of DML operations, without stopping if some operations encounter errors:

CREATE TABLE emp2 AS SELECT * FROM employees;DECLARE   TYPE NumList IS TABLE OF NUMBER;-- The zeros in this list will cause divide-by-zero errors.   num_tab NumList := NumList(10,0,11,12,30,0,20,199,2,0,9,1);   errors  NUMBER;   dml_errors EXCEPTION;   PRAGMA exception_init(dml_errors, -24381);BEGIN-- SAVE EXCEPTIONS means don't stop if some DELETEs fail.   FORALL i IN num_tab.FIRST..num_tab.LAST SAVE EXCEPTIONS      DELETE FROM emp2 WHERE salary > 500000/num_tab(i);-- If any errors occurred during the FORALL SAVE EXCEPTIONS,-- a single exception is raised when the statement completes.EXCEPTION  WHEN dml_errors THEN -- Now we figure out what failed and why.   errors := SQL%BULK_EXCEPTIONS.COUNT;   dbms_output.put_line('Number of DELETE statements that failed: ' || errors);   FOR i IN 1..errors LOOP      dbms_output.put_line('Error #' || i || ' occurred during '||         'iteration #' || SQL%BULK_EXCEPTIONS(i).ERROR_INDEX);      dbms_output.put_line('Error message is ' ||         SQLERRM(-SQL%BULK_EXCEPTIONS(i).ERROR_CODE));   END LOOP;END;/DROP TABLE emp2;In this example, PL/SQL raised the predefined exception ZERO_DIVIDE when i equaled 2, 6, 10. After the FORALL statement, SQL%BULK_EXCEPTIONS.COUNT returned 3, and the contents of SQL%BULK_EXCEPTIONS were (2,1476), (6,1476), and (10,1476). To get the Oracle error message (which includes the code), we negated the value of SQL%BULK_EXCEPTIONS(i).ERROR_CODE and passed the result to the error-reporting function SQLERRM, which expects a negative number. Here is the output:

Number of errors is 3Error 1 occurred during iteration 2Oracle error is ORA-01476: divisor is equal to zeroError 2 occurred during iteration 6Oracle error is ORA-01476: divisor is equal to zeroError 3 occurred during iteration 10Oracle error is ORA-01476: divisor is equal to zero

One problem that I'm faced with this is that if the specific 'exp_type' does not exist in the table for a given year, I get the "division by zero error.

TO_CHAR GROUP (date_exp, 'YYYY')

)
SELECT year 'year '.
Type
TO_CHAR ((Type/Type of NVL (LAG (Type) (any ORDER PER year)), * 100)-100, '999990') | ' %' "% increase.
OF THE total amount
ORDER BY year DESC

{code}

FYI - the: P1_YOY_PERCENT_LIST is just a value in the Apex that I use to allow users to select any 'exp_type' for who they want to see the increase in % of the previous year.

Thank you
Ryan

Hello

Yesterday was a great help by Frank et Al concerning a request for the increase of the % of the previous year

SQL to get % increase in the amount of the previous year

One problem that I'm faced with this is that if the specific 'exp_type' does not exist in the table for a given year, I get the "division by zero error.

It works fine when there are values for all years. Is there a way to get around this? Maybe the value null or 0 but not raise an error. I tried to use NVL but did not work

{code}

WITH total AS
(

TO_CHAR (date_exp, 'YYYY') SELECT an
SUM(CASE WHEN exp_type =:P1_YOY_PERCENT_LIST THEN exp_amt ELSE 0 END) AS Type
{code}

You are actually providing the 0 value in the ELSE clause. If you leave just off of the ELSE clause, then SUM returns NULL when there is no line with the given exp_type.
{code}
Sum(case when exp_type =:P1_YOY_PERCENT_LIST Then exp_amt end) AS Type
{code}
There is always a problem if exp_amt can really be 0 or exp_amt can be a combination of positive and negative numbers which could total 0.

{code}
Of exp_main
TO_CHAR GROUP (date_exp, 'YYYY')

)
SELECT year 'year '.
Type
TO_CHAR ((Type/Type of NVL (LAG (Type) (any ORDER PER year)), * 100)-100, '999990') | ' %' "% increase.
OF THE total amount
ORDER BY year DESC

{code}

FYI - the: P1_YOY_PERCENT_LIST is just a value in the Apex that I use to allow users to select any 'exp_type' for who they want to see the increase in % of the previous year.

The standard method to avoid division by 0 in x errors / when there may be 0 is
{code}
x / NULLIF (y, 0)
{code}
This returns null if y = 0. In your case, which would result in:
{code}
To_char ((Type
/ NULLIF (NVL (LAG (Type) (ORDER BY year)
Type
)
0
) * 100
) - 100
'999990'
) || '%' "% increase.
{code}
which guarantees that you will get the NULL value instead of the division by 0 error, but that means that the whole expression will be "%" when the number is NULL. If you really want the % sign in the set of results and not just the head, then use CASE, as Boneist suggested and cumulative Sven.

Divide by ZERO error.
