NULLIF() To Prevent Divide-By-Zero Errors In SQL By Ben Nadel on October 3, 2007 Tags: SQL Boyan Kostadinov just sent me a cool link to an article that is the final part in a four part series that discusses the oracle nullif divide by zero SQL NULL value. I haven't read the first three parts yet, but there is a really divide by zero error encountered. in sql cool tip in the fourth part on using NULLIF() to prevent divide-by-zero errors in a SQL call.The idea here is that, as with
Divide By Zero Error Encountered Excel
any other form of math that I know of, you cannot divide by zero in a SQL call. Therefore, running this code:
Vertica Nullif
results in a SQL error being thrown:Error Executing Database Query. [Macromedia] [SQLServer JDBC Driver] [SQLServer] Divide by zero error encountered.To prevent this sort of error from being thrown, author Hugo Kornelis suggests using a NULLIF() in the divisor of the equation. NULLIF() takes two arguments and returns NULL if the two values are the same and can be used to turn the divisor from a zero into a NULL which, in turn, will force the entire sql divide by equation to become NULL. Therefore, running this code:

Divide By Zero Error Encountered In Stored Procedure
with Oracle Database Latest Followup You Asked Hi Tom, My problem is oracle divide by zero exception handling of zero_divide exception. I'm using INSERT INTO T1 (SELECT... FROM T2) syntax. Tables T1 and T2 are redshift nullif known only at the runtime. SELECT contains many calculations as per example: SELECT C1/C2,C3+(C4/C5)... FROM T2 I would like to identify rowid of the row raising zero_devide exception. Thank you https://www.bennadel.com/blog/984-using-nullif-to-prevent-divide-by-zero-errors-in-sql.htm very much for everything that you done on this site. It is very helpful for me. Best regards. Mladen and we said... select decode( c2, 0, to_number(null), c1/c2 ) will accomplish your goal safely. Use decode to avoid evaluating a zero divide condition. Note: the to_number is not "extra", it is necessary to avoid implicit conversions to and from strings. Note2: https://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:16179197301219 I'm assumging when c2 is zero, the returned value should be "unknown", if it should be zero or some other number, it is OK to return that as well: decode( c2, 0, 0, c1/c2 ) Reviews Write a Review More or less the same problem February 17, 2005 - 9:29 am UTC Reviewer: Gabriel from Portugal My problem is that we have an application where the end user can introduce a formula, wich will eventually turned into a dynamic sql. The idea is to return a null if the expression encounters a zero-divide expression. Our options are - Use a function to wrap around the expression that would catch the zero-divide exception. I don't know how to solve this. - Parse the expressions the user can introduce. This is difficult to do. Do you know a way to implement the first solution ? Something I could use as follows : SELECT myfunc(C1/C2),myfunc(C3+(C4/C5))... FROM T2 Thank you so much for this and for your books, they have been very helpful.

ORA-01476 divisor is equal to zero tips Oracle Error Tips by Burleson Consulting divide by Question: I?m using this query and it's returning a divide by zero error: SELECT STUSECMTAMT.totdebit/STUSECMTAMT.totalcr, STUJOURNAL.cre_bal/(STUSECMTAMT.totdebit/STUSECMTAMT.totalcr) FROM STUSECMTAMT,STUDEG,STUJOURNAL WHERE STUSECMTAMT.vhno=STUJOURNAL.ref_no AND STUSECMTAMT.studegid=STUDEG.studegid;ERROR at line 1:ORA-01476: divisor is equal to zero Can anyone shed a bit more light on how to divide by zero detect and handle a divide by zero error?Answer: The Oracle oerr utility shows this on the divide by zero ORA-01476 error: ORA-01476 divisor is equal to zero Cause: An expression attempted to divide by zero. Action: Correct the expression, then retry the operation. You are dividing by 0. In your case, either: STUSECMTAMT.totalcr, (STUSECMTAMT.totdebit/STUSECMTAMT.totalcr) or STUSECMTAMT.totalcr equates to 0. You could use a decode or a case to capture the 0 and dtrap the condition without aborting the SQL. Resolving divide by zero using DECODE In the following example, a zero will be returned whenever the divisor is 0.DECODE(STUSECMTAMT.totalcr,0,0,STUSECMTAMT.totdebit / STUSECMTAMT.totalcr) Resolving divide by zero using CASE You could also try a CASE statement.CASE WHEN STUSECMTAMT.totalcr = 0 THEN 0 ELSE STUSECMTAMT.totdebit / STUSECMTAMT.totalcr END Using zero_divide to handle a divide by zeroTopic SQL Development View All BPEL in Oracle Open Source Java / J2EE Stored procedures XML PL/SQL Applications View All Enterprise and business performance management Implementing and upgrading Oracle apps E-Business Suite Fusion applications Hyperion JD Edwards (JDE) PeopleSoft Siebel and Oracle CRM Data Mgmt View All BI (business intelligence) Data quality Data warehousing Metadata Database Admin View All Cloud infrastructure Availability Backup and recovery Database design Export, import and migration Installation, upgrades and patches Oracle performance problems and tuning Oracle security Oracle DBA tools Error messages MySQL database Real Application Clusters (RAC) Development View All BPEL in Oracle Open Source SQL Java / J2EE Stored procedures XML PL/SQL Fusion View All Oracle and BEA Application Server Data and application integration SOA (service-oriented architecture) Infrastructure View All Cloud computing infrastructure Exadata and Exalogic Grid computing Oracle on Linux Operating system Oracle hardware decisions Virtual machine Oracle management View All certification Oracle acquisitions Business process management Market analysis DBA jobs training and certification Small businesses Regulatory compliance Outsourcing Oracle on demand and SaaS Oracle strategy and product roadmap Oracle support services Oracle vs. SAP Oracle Web 2.0 Sun-Oracle infrastructure View All Oracle cloud computing Oracle OS Oracle virtualization Topics Archive View All Oracle DBA jobs Oracle Resources Training and certification Tutorials, tips and FAQs Please select a category Applications Data Mgmt Database Admin Development Fusion Infrastructure Oracle management Sun-Oracle infrastructure Section Problem Solve News Get Started Evaluate Manage Problem Solve Sponsored Communities Q Using ISNULL or NULLIF to prevent division by zero Sections Share this ite
