it only takes a minute: Sign up PostgreSQL division by zero when ordering up vote 3 down vote favorite i need to execute this query in postgres but i couldn't get rid of this error ERROR: division by zero oracle sql divide by zero SQL state: 22012 here is the query : select id,rates_sum,rates_count from tbl_node order by rates_sum/rates_count DESC; i know i can add a small value to the rates_count but i get inaccurate values . Is there a way to make the postgres ignore this error ,or using if statement to check zeros and replace them with any number. and again the error in the order by clause. Thanks postgresql sql-order-by divide-by-zero share|improve this question edited Oct 1 '12 at 8:17 divide by zero error encountered in stored procedure Aziz Shaikh 11.5k73753 asked Nov 1 '10 at 9:26 ibmkhd 4142822 add a comment| 2 Answers 2 active oldest votes up vote 8 down vote accepted Use a CASE statement: SELECT id, rates_sum, rates_count FROM tbl_node ORDER BY rates_sum / (CASE rates_count WHEN 0 THEN NULL ELSE rates_count END) DESC NULLS FIRST; You could also use NULLS LAST, if you want to. share|improve this answer answered Nov 1 '10 at 10:25 Frank Heikens 48.4k128091 Thanks Man :), I will never forget this –ibmkhd Nov 1 '10 at 10:57 you could also use NULLIF instead of CASE to make it shorter (see sqlbrain.wordpress.com/2009/10/06/…) –Paul Nov 17 '14 at 15:50 add a comment| up vote 0 down vote how about a where rates_count != 0? share|improve this answer answered Nov 1 '10 at 9:28 SingleNegationElimination 83.6k12148211 i need to return all the nodes ,event if it has rates_count ==0 –ibmkhd Nov 1 '10 at 9:30 You can union it with another query with a where rates_count == 0 and another ordering. –SingleNegationElimination Nov 1 '10 at 9:45 can you please give me an example :),i tried but i get errors –ibmkhd Nov 1 '10 at 9:57 i cant put the order by in the first select ,and putting it for both will give me the same problem –ibmkhd Nov 1 '10 at 10:06 add a co

Error Division By Zero Postgresql
Error Message Server: Msg 8134, Level 16, State 1, Line 1 Divide by zero error encountered. Causes: This error is caused by performing a division operation wherein the denominator or the divisor is 0. This http://stackoverflow.com/questions/4067742/postgresql-division-by-zero-when-ordering error is not encountered when the denominator or divisor is NULL because this will result to a NULL value. Solution / Work Around: There are three ways to avoid the "Division by zero encountered" error in your SELECT statement and these are as follows: CASE statement NULLIF/ISNULL functions SET ARITHABORT OFF and SET ANSI_WARNINGS OFF Using the CASE statement, your query will look like the following: SELECT CASE WHEN [Denominator] = http://www.sql-server-helper.com/error-messages/msg-8134.aspx 0 THEN 0 ELSE [Numerator] / [Denominator] END AS [Percentage] FROM [Table1] If the denominator or divisor is 0, the result becomes 0. Otherwise, the division operation is performed. Using the NULLIF and ISNULL functions, your query will look like the following: SELECT ISNULL([Numerator] / NULLIF([Denominator], 0), 0) AS [Percentage] FROM [Table1] What this does is change the denominator into NULL if it is zero. Then in the division, any number divided by NULL results into NULL. So if the denominator is 0, then the result of the division will be NULL. Then to return a value of 0 instead of a NULL value, the ISNULL function is used. Lastly, using the SET ARITHABORT and SET ANSI_WARNINGS, your query will look like the following: SET ARITHABORT OFF SET ANSI_WARNINGS OFF SELECT [Numerator] / [Denominator] With both ARITHABORT and ANSI_WARNINGS set to OFF, SQL Server will return a NULL value in a calculation involving a divide-by-zero error. To return a 0 value instead of a NULL value, you can put the division operation inside an ISNULL function: SET ARITHABORT OFF SET ANSI_WARNINGS OFF SELECT ISNULL([Numerator] / [Denominator], 0) Related Articles : Frequently Asked Questions - SQL Server Error Messages Frequently Asked Questions - INSERT Statement Frequently Asked Questions - SELECT Statement
Christian Ready (@christianready) Using 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 https://www.bennadel.com/blog/984-using-nullif-to-prevent-divide-by-zero-errors-in-sql.htm to an article that is the final part in a four part series that discusses the SQL NULL value. I haven't read the first three parts yet, but there is a really 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 any other form of math that I know of, by zero you cannot divide by zero in a SQL call. Therefore, running this code:
