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
SELECT Client,State, CASE WHEN Weight>=11 and Weight<=455 and Height>=110 and Height<=250 THEN isnull((cast(nullif(Weight,0)/power((NullIf(Weight,0)/100),2) as int)),0) else -1 end as BaseBMIScore FROM Test100
And I got following error:
Msg 8134, Level 16, State 1, Line 1 Divide by zero error encountered.
How can I get the value (pr_profit / pr_sales ) * 100, (cur_profit / cur_sales) * 100 for %profit. When I am giving zero devide error is coming . How can I give if pr_profit = 0 then % profit should be zero.
SELECT SUM(CASE WHEN invdate >= {d '2015-01-01' } and invdate <={d '2015-11-03' } Then linetotal Else 0 End) as cur_Sales, SUM(CASE WHEN invdate >={d '2014-01-01' } and invdate <= {d '2014-11-03' } Then linetotal - linecost Else 0 End) as pr_Profit, SUM(CASE WHEN invdate >= {d '2015-01-01' } and invdate <={d '2015-11-03' } Then linetotal - linecost Else 0 End) as cur_Profit, SUM(CASE WHEN invdate >= {d '2015-01-01' } and invdate <={d '2015-11-03' } Then linetotal - linecost Else 0 End) -
I'm new at SSRS and writing functions. I don't have something right here, but can't see what it is. My function is:
Public Function TestDivide(Numerator as double, Divisor as double) dim retVal if Numerator <= 0 then retVal = 0 end if if Divisor= 0 then retVal =0 else retval = Numerator/Divisor end if return retVal End Function
I have to test both the numerator and divisor because either or both may be 0.
In the cell I call it with this formula, thinking that the black part is the first argument and the red part is the second. But SSRS tells me "Argument not specified for parameter "Divisor".
I am trying to divide 2 funcitons by each other and I am coming back with 0 as my result in one of them while I am getting the correct answer in another. The two columns I am trying to pull with functions are:
SELECT
sum(D.PrincipalBal)/sum(L.PrincipalBal)*100 as DelqRatioByBal , count(D.LoanID)/count(L.LoanID)*100 as DelqRatioByCnt
FROM Loan L
INNER JOIN DelqINFO D on D.LoanID = L.LoanID
I get the correct result back for 'DelqRatioByBal' but I get 0 back for 'DelqRatioByCnt'
aaaaa bbbbb date result ------- ------- -------- --------- a 100 7-7-15 a 100 7-7-15 a 100 8-7-15 b 200 7-7-15 b 200 8-7-15 b 200 8-7-15
I need this (divide bbbbb by row count as result, group by "aaaaa and date":
aaaaa bbbbb date result ------- ------- -------- --------- a 100 7-7-15 50 a 100 7-7-15 50 a 100 8-7-15 100 b 200 7-7-15 200 b 200 8-7-15 100 b 200 8-7-15 100
Can I do it?
My SQL Code is
(date=FEC, RESULT=COSTECUB, aaaaaa=TRACTA, bbbbb=TRAPR3) : SELECT VTRA00F.TRACTA, ACRDES, TRAPRL, TRAPR1, TRAPR2, TRAPR3, CASE WHEN TRAPR3 IS NULL THEN (CASE WHEN (ALLQDE+ALLQCN+ALLQCR+ALLQMR+ALLQNN+ALLQNR+ALLQV1+ALLQV2) <= TRAPRL THEN (TRAPR1*(ALLQDE+ALLQCN+ALLQCR+ALLQMR+ALLQNN+ALLQNR+ALLQV1+ALLQV2)) ELSE (TRAPR2*
I have typed a query by combining multiple tables to show sum of TotalReceivedAmount by MRN. It also have payment mode which is paid by cash or credit card. Now the query shows the sum for MRN combining all the payment done by credit card and cash. How am I supposed to show the amount paid by credit card and cash separately?
Here is the query :
SELECT Distinct dbo.CA_Payment.MRN, dbo.CA_Patient.FirstName, dbo.CA_PaymentModeMaster.Description AS PaymentMode, CASE (dbo.CA_Payment.PaymentModeID) WHEN 2 THEN dbo.CA_Payment.CardNumber END AS CreditCardNumber, CASE (CA_Registration.PatientTypeID) WHEN 1 THEN dbo.CA_PatientTypeMaster.Description WHEN 2 THEN dbo.CA_DebtorMaster.DebtorName END AS Debtor,
When running a query such as this on a database view:
select count(*) from WWALMDB.dbo.v_AlarmEventHistory2
SQL throws the following error:
The datediff function resulted in an overflow. The number of dateparts separating two date/time instances is too large. Try to use datediff with a less precise datepart.
Oddly on a Table the count(*) function works.
Is there a limit on views or the count(*) function that I am not aware of?
I have a few tables I am trying to join to create a report. Everything was working fine until I tried to add an aggregate Sum function to a column (MaxCap) in table ctfBarn.
I've written sql code which takes a date and finds the Last Day of the Month one year ago. For example, it takes the date '2015-04-17' and returns the date '2014-04-30'. The code works fine in a query. Now I'm trying to turn this into a function. However, when I try to create the function I get the error:
Operand type clash: date is incompatible with int
Why is this error being returned?
Here is my function:
CREATE FUNCTION dbo.zEOM_LY_D(@Input Date) RETURNS date AS BEGIN; DECLARE @Result date; SET @Result = convert(DATE, DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,dateadd(m, -11, @Input)+1),0)),101) RETURN @Result; END;
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?
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
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
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:
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? -Larry
Hi Is there a way to prevent this error? I'm getting it from query line: 10000 * (SELECT count(filial_cotacao) from negocios_cotacoes where filial_cotacao = cod_filial)) / (22 * 6 * (SELECT count(filial_cotacao) from negocios_cotacoes where filial_cotacao = cod_filial)),1) 'Atingimento Semestre' Thanks a lot
Some of my calculated members look like "######" in Excel and I believe it is because of divide by zero errors. I have tried right clicking on the table, selecting "Table Options" and "For error, values, show:" I have enter 0. This is not working. Does anybody know how to get rid of this.
I have one table with columns patientName , Nurse,ArrivalDate, DepartDate . It has all the patiet information for all the Nurses.
I am calculating Average Number of patients per day per nurse by using below query
SELECT Nurse, COUNT(DISTINCT patientName) AS NoOfPatients, COUNT(DISTINCT patientName) * 1.0/COUNT(DISTINCT ArrivalDate) AS [AvgNo.ofpatientsPerDay] FROM Table t GROUP BY NURSE
but if ArrivalDate is Null I am getting below error saying that Divide by zero error encountered.
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
I am trying to work with a developer test a code change in their application. The db basically has a workload table and as it finishes processing each row in the table, it gets deleted from the table. I want to monitor when the db becomes empty/no rows in it to test how much the code changes have worked, how long does it take to process all rows in the table. Any quick way to do it at the db level instead of having to put something in the code just for this testing.
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.
I have SSRS 2012 and have a report with an expression shown below. I am getting an error of
"[rsRuntimeErrorInExpression] The Value expression for the textrun ‘Textbox133.Paragraphs[0].TextRuns[0]’ contains an error: Attempted to divide by zero."
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.
Does anyone know how to get over their dreadfull divide by zero error. I keep getting the error, i have changed this code so much. I need to get the percent increase from 2007-2008 ("Total") in this table grouping. I know im getting the error in some of the fields, because sometimes the total is 0 and sometimes the 2007 is 0. What do i do?
When i exec an sp it runs a sum, sometimes it is possible that there is a 0 value, it then returns an error Divide by zero error encountered How can i work around this error
My sp code is
CREATE proc CP_avgloss_rings @mID varchar(10), @startdate datetime, @enddate datetime as select ((sum(vtp)-(sum(moneyout)))/100) / ((sum(playtime))/ 3600) as avgloss from dbo.rings where machineID = @mID and convert(varchar,njdate,121) between convert(varchar,@startdate,121) and convert(varchar,@enddate,121) GO

I'm new to this forum. This 'problem' has occured many times, but I've always found a way around it. I have pages with datagrids, in which a user can edit a certain fields and then update the tables with new data. Lets say when a user edit a Name field and a money field. If he/she left those two fields blank, the table is automatically updated with a <null> (for the name field) and a 0 (for the money field.) Both these columns were set up to allow Null values. Anyone has an idea why they were updated that way? And is there like a standard on how the data types are updated if a field is left blank? Thank you very much.
