I know you can resolve "divide by zero" messages with a CASE statement.
However, the T-SQL docs suggest that I should be able to simply turn off both the error message and the effect of the error with
SET ARITHIGNORE ON
and
SET ARITHABORT OFF
I am trying to execute these two statements within a stored proc but I need their effect to reach to a select statment that is a sql string (as in 'EXECUTE (@SQLSTRING)' within the same stored proc.
Am I wrong to expect these statements to be able to deal with "divide by zeroes"?
I haven't been able to make it work so I would appreciate any pointers that someone might have.
would have a result set like (this is not an exact result from analyser)
empname empsalary ----------- ------------ Imran 5000 Raja 5000 Ram 8000
But I was wondering if I could somehow make it display
Imran 5000 Raja 5000 Ram 8000
I actually implementation of this is something vast, but I have illustrated a very simple example to explain what I want to achieve. Might seem a very simple 1 line solution, but I haven't been able to find it. .If ther is any documentation that might help please reply and point me to that..
Hi. Is there a way to supress a system generated error messages?
I have a stored procedure that I'm executing from Query Analyzer that updates a table and potentially generates a foreign key violation. I am trapping and handling the error, but the system generated message still displays. Is there a way to supress these messages (other than pre-checking for the condition prior to updating)?
I have a field that divides one field by the sum of two others. However, when both of the two latter fields are 0's, I get a divide by zero error and the output halts. How do I get this so that for these records I put a NULL or UNDEFINED or something in there at least so I can see the rest of the output. Thanks.
I have this sql posted below which sometimes gets a divide by zero error. How can you get around this error please
SELECT COUNT(DISTINCT dbo.safety_obs_data.form_id) AS TotalObs, SUM(dbo.safety_obs_data.safe) AS TotalSafe, SUM(dbo.safety_obs_data.unsafe) AS TotalUnsafe, CONVERT(decimal(18, 2), (SUM(CASE WHEN (safe) * 100.0) / (SUM(safe) + SUM(unsafe)))AS [% Safe], SUM(CASE WHEN unobserved = 1 THEN 1 ELSE NULL END) AS NotSeen, SUM(CASE WHEN made_safe = 1 THEN 1 ELSE NULL END) AS TotalMadeSafe, SUM(CASE WHEN sap_note = 1 THEN 1 ELSE NULL END) AS TotalSAPNote, SUM(CASE WHEN honk = 1 THEN 1 ELSE NULL END) AS TotalHonks, dbo.Employee.emp_user_id FROM dbo.safety_obs_data INNER JOIN dbo.Employee ON dbo.safety_obs_data.create_by_emp_no = dbo.Employee.emp_no WHERE (dbo.safety_obs_data.create_dte BETWEEN CONVERT(DATETIME, @start, 102) AND CONVERT(DATETIME, @end, 102)) GROUP BY dbo.Employee.emp_user_id

--- Note: How can I avoid the the error message if the dividend and the divisor are both 0?
When I specify a formula between Computed Column Specification, I have twozero values, getting Divide by Zero error, any idea how can I avoid this? Istill want SQL Server to display Zero if it is 0/0, is this possible in SQLServer database?ThanksJ.
In the BI developement, in a matrix i'm trying to avoid division by zero, but even if i test the field before the division, i've got the error everytime.
I put the folowing test condition in the field, but i've got an error.
Ex : iif(Turnover <> 0, Cost/Turnover,0)
But i've got error message when the turnover is 0.

I am having a terrible time with a stored procedure. I think it has something to do with a divide by zero issue. Here is my sproc:
ALTER PROCEDURE [dbo].[GetPlayers] @TeamID int AS SELECT PlayerID, TeamID, FirstName, LastName, FirstName + ' ' + LastName As Name, "SPct" = CASE (SELECT Count(PlayerID) FROM GameDetail WHERE AtBatID IN(1, 2, 3, 4) AND GameDetail.PlayerID = Player.PlayerID) WHEN 0 THEN 0 ELSE Cast ( Cast ( ( (SELECT Count(PlayerID) FROM GameDetail WHERE GameDetail.PlayerID = Player.PlayerID AND AtBatID = '1') + (SELECT Count(PlayerID) FROM GameDetail WHERE GameDetail.PlayerID = Player.PlayerID AND AtBatID = '2') + (SELECT Count(PlayerID) FROM GameDetail WHERE GameDetail.PlayerID = Player.PlayerID AND AtBatID = '3') + (SELECT Count(PlayerID) FROM GameDetail WHERE GameDetail.PlayerID = Player.PlayerID AND AtBatID = '4') / (SELECT Count(PlayerID) FROM GameDetail WHERE AtBatID IN(1, 2, 3, 4) AND GameDetail.PlayerID = Player.PlayerID ) * 1.0 ) As int ) As Decimal(4,3)) End FROM Player WHERE TeamID = @TeamID ORDER BY FirstName, LastName
Here is the error I get when I run this: Msg 8115, Level 16, State 8, Procedure GetPlayers, Line 9 Arithmetic overflow error converting int to data type numeric. So the results should look like: .333 or .500 or .000
It's driving me crazy. I have tried everything but cannot get the desired results. I'm hoping someone can help me.
this is from a SQL playbook i don't understand the logic of DIVIDE when you use more than one NOT EXISTS
such as this query
select distinct itemname from qdel del where not exists (select * from qspl where not exists (select * from qitem where itemtype='n' and not exists (select * from qdel where qdel.itemname=qitem.itemname and qdel.splno=qspl.splno)) and not exists (select * from qdel where qdel.itemname = del.itemname and qdel.splno=qspl.splno))
i don't understand how can NOT EXISTS code brings out the results of the existing rows in those not exists lines like it says NOT EXISTS itemtype 'n' etc. but that is the results!
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 have a query that goes against an Oracle 9i database. I have run it in RS and in native oracle environment and get the same query results. I have guaranteed there are no NULL values.
If I structure the expression (as a 0 value test) it works fine. It puts 0/1 for in the result field correctly.
=iif(Fields!LDLM.Value = 0, 0.0, 1.0)
If when I put in the actual divide statement I get a zero divide error.
help... I have a field called PercentVar_P4 which really is budget - actuals... I need to create an expression that will that the
PercentVar_P4/budget.. when I do I get Infinity and nan... I want to see the negative number.. I have read through all the blogs and nothing seems to fit..
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 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

but if ArrivalDate is Null I am getting below error saying that Divide by zero error encountered.

Not sure if in SQL server i can correct the problem like that, any help is greatly appriciated...
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
