Single developer app, so enforcement not so difficult except for my memory. :-) –Ron Savage May 14 '09 at 15:02 2 Despite the print statement, it's not a stored proc, I am finding values 0,0,0,0 in all fields.for example.I have 6 fields created in my form.1 NAME 2.CITY NAME 3.E-mail id 4.Contact No 5.Pass and 6.Comments Area in my form. So Edwardo asks in the comments "what if the user puts in a 0?", and he advocates that it should be okay to get a 0 in return. Generally speaking I would want 0 when I divide sorry! his comment is here

If the subquery is a SELECT that accesses another table, concurrency effects can also produce this behaviour. The usual 'gotcha' is than most developers expect SQL to behave like procedural languages and offer logical operator short-circuit, but it does NOT. So it would be: Percentage = ISNULL(100 * ClubTotal / NULLIF(AttTotal, 0), 0) The inner part is evaluated to NULL and then ISNULL replaces it with 0. Thanks.Reply Logan December 29, 2014 8:04 amThe denominator resolves to 0 since all numbers are integers and inside of the parenthesis the division is solved from left to right. 17/17 =

Sql Division By 0 What precisely differentiates Computer Science from Mathematics in theoretical context? What is the best way to write SQL code so that I will never see this error message again?

Even if you write your query differently using ISNULL or NULLIF at the end it will likely execute the same. –Nenad Zivkovic Oct 28 '13 at 9:34 As has http://www.bennadel.com/blog/984-using-nullif-to-prevent-divide-by-zero-errors-in-sql.htm Everybody who's used SQL for any amount of time knows that we can use a CASE expression to prevent division by zero. Sql Error Divide By Zero Error Encountered Rewrite the query as: SELECT club_id, males, females, males/NULLIF(females, 0) AS ratio FROM school_clubs; Any number divided by NULL gives NULL, and no error is generated.

COALESCE is more complex function and capable to accept any number of parameters while isnull/nvl are tailored to replace NULL value from one single column with something different and do it How does an exponent work when it's less than one?

Or any other number :-) Returning zero implies ClubTotal is zero and AttTotal is more than zero. –Tom Chantler Oct 28 '13 at 9:38 add a comment| Did you find this How to put text above a node/point in tikz How much should the average mathematician know about foundations? The reason is that SQL Server evaluates the source expression twice when it expands NULLIF into the equivalent CASE expression. weblink This will give you the percentage distribution of males and females in a club, like 31% men, 69% women. –George Nov 26 '15 at 18:04 add a comment| up vote 28
The business rule is that to calculate inventory turns, you take cost of goods sold for a period, annualize it. Oracle Sql Divide By Zero Thank you very much. –Henrik Staun Poulsen Dec 17 '13 at 20:01 It works on complex queries! This will save me gobs of time plus keep my code less complicated.
Is there better way, or how can this be enforced? Or you would create strings (e.g. '10.50%') rather than numbers (e.g. 10.5%), containing "No att.

I'm looking at calculating the number of inventory turns that occur in a three month period. Which means you need to travel up the line and figure out why you're getting 0 or be acceptable with returning null. 0 is never correct in this instance. –James Wilson please help.ISNULL(table/NULLIF((table),0),0)*100 Lain Inverse Oct 21, 2012 at 3:29 AM 2 Comments Addendum:In case when divisor could be NULL it's important to NVL it to ZERO. check over here But somehow query optimizer do divide by zero while filtering.
