8 knows that division by zero is a no-no, or at least they should. Everybody who's used SQL for any amount of time knows that we can use a CASE expression to prevent division by zero. But do you know division by zero error in access the other way to prevent division by zero in SQL? Assume a database file called SomeTable, division by zero error in access report with fields called Quantity and Amount. Let's divide Amount by Quantity. First, here's the usual case statement. select itnbr, Amount, Quantity, case when

Quantity <> 0 then Amount / Quantity else 0 end from SomeTable If Quantity is not zero, the division takes place. If Quantity is zero, the calculation yields a zero. We could just as easily return any other numeric value, http://community.teradata.com/t5/Database/Division-by-zero-Error/td-p/11128 the value one, for example. select itnbr, Amount, Quantity, case when Quantity <> 0 then Amount / Quantity else 1 end from SomeTable The other way to prevent division by zero is to use the NULLIF function. NULLIF requires two arguments. If the arguments are equal, NULLIF returns a null value. If they are not equal, NULLIF returns the first value. Here's the SQL. select itnbr, Amount, Quantity, Amount / nullif(Quantity,0) from SomeTable If Quantity is not zero, the http://www.itjungle.com/fhg/fhg051210-story02.html two arguments do not match, and the resulting calculation is Amount divided by Quantity. But if Quantity is zero, the arguments do match, and the calculation is Amount divided by null, which yields a null value. If you use this technique, be sure to put the zero in the second argument of NULLIF.

By Chris FehilyJul 25, 2008 Topics: ProductivitySuppose you http://www.peachpit.com/blogs/blog.aspx?uk=Avoiding-division-by-zero-with-NULLIF-Five-SQL-Tips-in-Five-Days-Part-5- want to calculate the male–female ratios for various school clubs, but you discover that the following query fails and issues a divide-by-zero error when it tries to calculate ratio for the Lord of the Rings Club, which has no women: SELECT club_id, males, females, males/females AS ratio by zero FROM school_clubs; You can use the function NULLIF to avoid division by zero. NULLIF compares two expressions and returns null if they are equal or the first expression otherwise. Rewrite the query as: SELECT club_id, males, females, males/NULLIF(females, 0) AS ratio FROM school_clubs; Any number divided by division by zero NULL gives NULL, and no error is generated.
