error: division by zero postgresql

isnull sql

sql divide by null

**This question already has answers here**:

You want to check if the denumerator of the division is zero, and return `NULL`

instead in this case. This will cause the division to return `NULL`

as well, which is likely what you want.

Without knowing your RDBMS, here is an implementation that relies on a `CASE`

statement, which is supported in most (if not all) SQL servers.

SUM(PMCLY.[Net Sale LY]/( CASE WHEN PMC.[Net Sales] - PMCLY.[Net Sale LY] = 0 THEN NULL ELSE PMC.[Net Sales] - PMCLY.[Net Sale LY] END )) AS 'VAR Vs LY %'

If your RDBMS supports `NULLIF`

, then :

SUM(PMCLY.[Net Sale LY]/( NULLIF( PMC.[Net Sales] - PMCLY.[Net Sale LY], 0) )) AS 'VAR Vs LY %'

**Formula issue in SQL when one result has 0 value,** You want to check if the denumerator of the division is zero, and return NULL instead in this case. This will cause the division to return NULL as U can make use of a combination of the NULLIF and ISNULL functions. The NULLIF can be used to prevent the divide by zero errors. The ISNULL can be wrapped on the outside, to set a default value in such cases. In your case, that would be 0. Something like this: SELECT ISNULL (10 / NULLIF (0, 0) , 0) -- result = 0 Your code example would look like this:

this will work:

SELECT case when mod((5/(decode(0,0,5,1))),1) = 0 then 0 else (5/(decode(0,0,5,1))) end FROM dual; 0 SELECT case when mod((5/(decode(2,0,5,2))),1) = 0 then 0 else (5/(decode(2,0,5,2))) end FROM dual; 2.5

for your case :

SELECT sum(case when mod((PMCLY.[Net Sale LY]/(decode((PMC.[Net Sales] - PMCLY.[Net Sale LY],0,5,(PMC.[Net Sales] - PMCLY.[Net Sale LY]))),1) = 0 then 0 else (5/(decode((PMC.[Net Sales] - PMCLY.[Net Sale LY],0,5,(PMC.[Net Sales] - PMCLY.[Net Sale LY])))) end FROM tablename;

**Two Ways to Prevent Division by Zero in SQL,** 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. If none of the comparison values equal the test value, then the expression takes on the value resultx. Again, if the optional ELSE clause isn’t present and none of the comparison values match the test value, the expression receives a null value.

U can make use of a combination of the NULLIF and ISNULL functions. The NULLIF can be used to prevent the divide by zero errors. The ISNULL can be wrapped on the outside, to set a default value in such cases. In your case, that would be 0.

Something like this:

SELECT ISNULL (10 / NULLIF (0, 0) , 0) -- result = 0

Your code example would look like this:

ISNULL (SUM (PMCLY.[Net Sale LY] / NULLIF ( (PMC.[Net Sales] - PMCLY.[Net Sale LY]), 0 ) ), 0) AS 'VAR Vs LY %'

**Replacing NULL with 0 in a SQL server query,** How do I show null values as zero in SQL? SQL DBA,SQL Server MVP(07, 08, 09) Prosecutor James Blackburn, in closing argument in the Fatal Vision murders trial: "If in the future, you should cry a tear, cry one for them [the murder victims].

**SQL - NULL Values,** By default, SQL Server has a default value of SET ARITHABORT is ON. We get SQL divide by zero error in the output using the default behavior. similar to a client application while troubleshooting the performance issues. When scientific formula return infinity, science reconsiders the inquiry's premise. Formula for if cell value less than 0, display 0 or if greater than 0, display cell value I have figured out part 1 of this formula - IF(A1<0, 0) but I would like to display the cell value if it's greater than 0: i.e. IF(A1<0, 0), IF(A1>0, ???)

**SQL Interview Questions,** The value for each tenure can be calculated in SQL: SELECT Tenure, When the results are copied into Excel, one column has Tenure, one column popt, The following formula in cell H27 calculates survival: =IF($C27=0, 1, H26*(1-G26)). Search and replace # formula errors with 0 or blank cells with Go to command. This way is able to convert all # formula errors in a selection with 0, blank or any other values easily with Microsoft Excel's Go To command. Step 1: Select the range that you will work with. Step 2: Press the F5 key to open the Go To dialog box.

However, users often submit keywords which appear as text values and have low select (1/2) as result Result: 0 You would expect the result to be "0.5" but what we actually get is "0". The solution to this is to CAST or CONVERT the numerator to a float in the query so that SQL Server does not round the result to a whole number.
