How To Avoid Divide By Zero Error

Nov 6, 2013

I have some SQL scripts for SQL Views and getting divide by zero error. I am using

COALESCE(Field1,Field2,1)/COALESCE(Field3,Field4,1)

This function can avoid NULL but how I can avoid 0 ?

Is there any function in SQL that can take care both NULL and 0 and replace it with 1.

Divide By Zero Error

Feb 24, 2006

Hello,

When I execute the following query, I get a Divide by zero error. I believe the Divide By zero error is occuring in the following statement. How do I avoid the error?


ModelDiff = CONVERT(decimal (8, 4), abs(yest.ModelValue-today.ModelValue)/abs(yest.ModelValue))


drop table #MaxArchiveDates
DECLARE @MaxArchiveDate INTEGER
, @EdgeModelID INTEGER
, @DefinitionID INTEGER
SELECT ArchiveDataDate = MAX(ArchiveDataDate) INTO #MaxArchiveDates FROM intldbArchive.dbo.GOModelUniversesSaveD
UNION SELECT ArchiveDataDate = MAX(ArchiveDataDate) FROM intldbArchive.dbo.GOSecurityGroupModelValSaveD
UNION SELECT ArchiveDataDate = MAX(ArchiveDataDate) FROM intldbArchive.dbo.GOSecuritiesSaveD
UNION SELECT ArchiveDataDate = MAX(ArchiveDataDate) FROM intldbArchive.dbo.GOUniverseSecurityMembeSaveD
SELECT @MaxArchiveDate = MIN(ArchiveDataDate) FROM #MaxArchiveDates
SELECT @MaxArchiveDate
SELECT ModelID = today.ModelID
, RelativeUniverseID = today.RelativeUniverseID
, SecurityID = today.SecurityID
, ModelValueT = CONVERT(decimal (8, 4), today.ModelValue)
, ModelValueY = CONVERT(decimal (8, 4), yest.ModelValue)
, ModelDiff = CONVERT(decimal (8, 4), abs(yest.ModelValue-today.ModelValue)/abs(yest.ModelValue))
FROM OptMod.dbo.GO_SecurityGroupModelValues today
JOIN intldbArchive.dbo.GOSecurityGroupModelValSaveD yest
ON today.SecurityID = yest.SecurityID
AND today.ModelID = yest.ModelID
AND yest.ArchiveDataDate = @MaxArchiveDate

Thanks in advance!!!

Divide By Zero Error

Feb 28, 2006

I am writing a report that deals with time in seconds. I am trying to figure out the average handle time for each call.
To Get this number i use 5 fields. the formula is

(((cs_acd_trk_t + cs_acd_ext_c)/(cs_acd_trk_c + cs_acd_ext_c)) + ((cs_t_acd_wrk)/(cs_acd_trk_c + cs_acd_ext_c))/(cs_acd_trk_c + cs_acd_ext_c))

Which translates to ((Incoming Handle Time) + (Work))/(Number of Incoming Calls)

When it does the calculations some times the cs_acd_trk_c + cs_acd_ext_c (number of incoming calls) is zero.

I dont know how to get around this ... i tried to set that value to <>0 in my query but it threw my other numbers off for number of calls which is a different value on the report.
Any Help on this would be super appreciated.
Thanks,
Mitch

Divide By Zero Error Only With Top

Sep 27, 2006

In the following expression, the query executes with no errors (there are sometimes 0's and nulls in IRON and ENERGY):

SELECT * FROM gff2vg

WHERE (gff2vg.ENERGY > 0 and gff2vg.IRON > 0)

order by IRON/ENERGY desc

but when TOP is added there is a divide by zero error. Is there a way to avoid this?

SELECT TOP(64) * FROM gff2vg

WHERE (gff2vg.ENERGY > 0 and gff2vg.IRON > 0)

order by IRON/ENERGY desc



Thanks.

#Error Using IIF And Divide By Zero

Jan 19, 2007

I am getting an error in a calculated field that could potentially divide by zero, even though I'm using an IIF. The column displays in the report as "#Error". My expression looks like this:


= IIF(Fields!Qty.Value = 0, "None", Fields!Hours.Value / Fields!Qty.Value)

I have successfully used this approach with INT fields, but this time the Hours field is a NUMERIC(9,2). My workaround is to do this:


IIF(Fields!Qty.Value = 0, "None", IIF(Fields!Qty.Value = 0, 42, Fields!Hours.Value) / Fields!Qty.Value)
I guess the 42 is cast to an INT inside the second IIF and the calculation works.
What's strange is that the division would even be carried out in the event of Qty = 0 from the first IIF, because the expression should just evaluate to "None" and that would be that.
Has anybody run into this problem? Is my workaround the recommended approach?

Divide By Zero Error Trapping

Jul 20, 2005

I have the following line in a select statement which comes up with adivide by zero error.CAST(CASE Splinter_StatusWHEN 'SUR' THEN 0ELSE CASE WHEN Sacrifice>=1THEN 3*m.Premium/100-(m.Sacrifice * 3*m.Premium/100)/(m.Gross+m.Sacrifice)ELSE 0ENDEND AS Float)AS Bond2,The error happens on the section (m.Gross + m.Sacrifice) as this canequal zero and throws out the part of the calc that divides by it. Itis correct in some instances that it does so. The full SQL statementhas a large number of these expressions so I need a method I can applyto any line if possible.I know that it is mathmatically correct to error where this value iszero, but what I want to do is set the output of the entire expressionto zero if there is an error.Realistically an error such as this could happen at a few points inthe expression (or one of many others), so I need to find a way ofcatching any error in the expression and setting the return value to0. I thought of using a CASE statement, but wondered if there was abetter way of looking at this as the case statement would have tocheck each variation where it could throw an error.Any ideas ?ThanksRyan

Wht Does This Give Divide By 0 Error?

May 24, 2007

I am using iif which works just fine in Access to prevent divide by zero errors but this:



=iif(Fields!oh_ret.Value<>0,(Fields!oh_ret.Value-Fields!oh_cost.Value)/Fields!oh_ret.Value,"")



Fails



As Does:





=iif(Fields!oh_ret.Value=0,"",(Fields!oh_ret.Value-Fields!oh_cost.Value)/Fields!oh_ret.Value)



Why? How do I get around this?

Transact SQL :: Divide By Zero Error

Oct 25, 2015

I have an equation 

( ( P.RealisedConsumption / ( NULLIF(( PO.ActualQty * P.QuantityPO ), 0) / NULLIF(1000000, 0) ) ) - 1 ) * 100 AS FibreScrapFactor

This works for the example order that I am looking at.  However if i take out the where clause (so i have all orders) i get divide by zero error.  

If I limit the / 1000000 to 10 which i then have 

( ( P.RealisedConsumption / ( NULLIF(( PO.ActualQty * P.QuantityPO ), 0) / NULLIF(10, 0) ) ) - 1 ) * 100 AS FibreScrapFactor

This works for all orders, but is incorrect I need to divide by a million.  How can I get this to work?

T-SQL (SS2K8) :: Eliminating Divide By Zero Error

Oct 21, 2014

Being one step removed from innumerate, I was wondering whether there was a more elegant way to avoid divide by zero error instead of trudging through a bunch of isnulls.

My intuition tells me that since multiplication looks like repeated addition, that maybe division is repeated subtraction?
If that's true is there a way to finesse divide by zero errors by somehow reframing the statement as multiplication instead of division?

The sql statement that is eating my kishkas is

cast(1.0*(
(ISNULL(a.DNT,0)+ISNULL(a.rex,0)+ISNULL(a.med,0))-(ISNULL(b.dnt,0)+ISNULL(b.rex,0)+ISNULL(b.med,0))/
ISNULL(a.DNT,0)+ISNULL(a.rex,0)+ISNULL(a.med,0)) as decimal(10,4)) TotalLossRatio

Is there a way to nucleate the error by restating the division? My assertion underlying this statement is that the a alias represents a premium paid, so between medical, pharmacy and dental, there MUST BE at least one premium paid, otherwise you wouldn't be here. the b alias is losses, so likewise, between medical, pharmacy and dental, there MUST BE at least one loss (actually, it just occurred to me that maybe there are no losses, but that would be inconceivable, but ill check again)) so that's when it struck me that maybe there's a different way to ask the question that obviates the need to do it by division.

Textbox 133 has an expression as shown below and I cannot figure out why I get the error because I thought the IIF would bypass divide by zero.

Transact SQL :: Divide By Zero Error In Empty Function

Oct 9, 2015

I have a work database where I implemented a table-valued function. One colleague of mine reported to me that this function gave a Divide by Zero error when executed with some specific values given to its arguments (there are a 15 arguments). Then I started debugging, and I introduced some exit points to the function before its end in order to detect the point where the error appeared, since I don't have access to the database server and I cannot use the debugging tools from remote, due to the network configuration of my office. I can only do attempts on the code to try to find a solution.

Since I didn't manage to get rid of this error, I decided to make a silly and desperate attempt: I put a RETURN statement immediately after the BEGIN of the function body, with the idea that the function should not raie any error if it exit immediately after its beginning, despite the fact that this results in an empty table in return.

The result of my attempt is that the Divide by Zero error is still THERE (!), even if my function looks like

ALTER FUNCTION [dbo][<myFuncName>](...parameters...) RETURNS TABLE (...table definition...) AS BEGIN 
RETURN
END 
GO

How I can check it.

How Can I Avoid That The OLEDB Provider Intercepts The Error?

I have an stored procedure which is called by using ADO and OLEDB. I wish that when an error occurs (such as when a contraint is violated or trying to insert NULL in a not-null column) the error message is stored on an output parameter and returned to the client, without the error being raised by the OLEDB Provider.

How can I do that?

Thanks a lot in advance.

Object Validation To Avoid Invalid Object Name Error

Sep 27, 2007



There are certain errors that does not come during compilation and it shows during execution because of late-binding concept implemented in SQL Server from 7.0 version.

The problem is when Tables are not there, SPs are created. And there is no option where we can set like 'Validate object resolution during compilation"

There are lot of SPs that are in invalid status because the tables are really not there and SP needs to be modified to reflect the correct table name. In Oracle, if I have to find the list of objects that are in invalid state (because of object resolution problems), it was possible. How do I do it in SQL?

I need a listing of all objects in my database that is in invalid state. Searched in NET but there seems to be no supporting tool also that lists invalid objects.

Pl let me know whether there exists a way by which I can get to know the invalid object lists in my SQL 2005 database
