Hi,
Can anyone tell me why this doesn't return any decimals?
declare @f float
set @f = 6 / 18
print @f
All i get is 0... Is there something obvious i've done wrong?
TIA

Hi all,
I have a prob with the following code...
in that the value of the amount of the year 2001
is 0 so it is showing me division by zero prob
can any one change the code and let me know the details
declare @year1 int
declare @year2 int
declare @month int
set @year1 = 2002
set @year2 = 2001
set @month =9
select
case when sum(case WHEN a.oper_year = @year1 THEN a.amount else 0 end) = sum(case WHEN a.oper_year = @year2 THEN a.amount else 0 end) then 0
else
(
(sum(case WHEN a.oper_year = @year1 THEN a.amount else 0 end) -
sum(case WHEN a.oper_year = @year2 THEN a.amount else 0 end))/
sum(case WHEN a.oper_year = @year2 THEN a.amount else 0 end)
)* 100 end as Percentage,
from oper_sundata a, oper_type_new b
where a.site_id = b.sun_site
Thanks
I'm very new to sql server and still don't know the in's and out's I have this:
Sum(Case WHEN dbo.THIT_RATIO_DETL.STATUS_CD = "B" or dbo.THIT_RATIO_DETL.STATUS_CD = "K" THEN 1 ELSE 0 END)/ Count(dbo.THIT_RATIO_DETL.SUBMISSION_NO)as Per_Quoted
I keep on getting 0, anybody have any ideas?
In my query, there's a mathematical expression that takes a value from one table and divides it by another value (X).
The problem is that X can be 0 sometimes and then I get an error.
How can I prevent errors like this for the case of X=0?
In access I would use IIF function, but it doesn't appear in SQL SERVER views.
Thanks.
Hi,
I'm trying to divide two decimal(19,4) numbers but it keeps giving me a Divide by 0 error.
- 10698.25 / 76782.11 = -0.13 (but I get a Divide by 0)
I looked it up in the Sql Server docs, does the Divide by 0 error also cover Stack overflows?
If so, how do I get around this?
Many thanks,
Stuart
This query is part of a larger query that updates a table that holds statistics for reporting. It yields actual Unit per Minute by plant by month. Some of the plants don't produce anything in certain months, so I'm ending up with a Divide by Zero error. I think I just need to stick another CASE statement in for each month, but that seems like it could get pretty ugly.
Any suggestions on how to improve this?

hi
in a view, i create a field like field1/field2.
in case that field2 is zero, i've got division by zero error.
how can i change the value to 0 when field2 is 0 for avoiding get error.
I want to count the rows in two tables and then give a percentage as a result.
Something like:
SELECT Count(*) / (SELECT COUNT (*) FROM Table2) FROM Table1
Just not quite sure how to do this.
*Thanks*
It is common for me to need to create ratios from data in my database such as
SELECT
( list_value / sale_price ) as ratio
FROM
values
The value returned is always an integer whether decimal is cast or not. IE if sale_price is > list_value then 1 or 0 is returned instead of the percentage (ratio) as expected. Only whole numbers are returned.
BTW. Same is true in postgres db I have as well. What is it that I am doing wrong?

Hi,
I have a table in which i have two colums say discription and counts.
the table has 10 rows.
This table is created by extracting data from other table means its not a table that exist in system.
Now in my last row i want discription as '%mailed' and count as row1/row2
can u tell me how to do that?

I've got the following SQLSELECT count(*) FROM tablea AJOIN tableb B ON ..etc..WHERE a.string_val = 'test' ANDb.divider 0 ANDa.number 0 AND(a.number / b.divider 0)The b.divider value can be 0, but still I get the division by zeroerror message.I guess the reason is that the database performs the where statementsone at the time?So when performing the division a.number / b.divider it could get 0 inthe divider even if b.divider 0 is also part of the wherestatement??My question is then.. How can I work around this problem? Changing thedatabase to set b.divider always 0 is not an option

I plan to implement UDT for division methods.
The following fragment TSQL with zero check:
DECLARE @a int, @b int
SELECT
CASE WHEN @b = 0 THEN NULL
ELSE @a / @b
END
Clr UDT may look like this and script will be shorter.
DECLARE @a int, @b int
SELECT @a Type :: divide(@b)
Is that better to use UDT ?
Anyone have try this before?
Could anyone explain the difference between the following 3 queries?
select CONVERT(decimal(38,25),100) / CONVERT(decimal(38,25),1750)
select CONVERT(decimal(19,8),100) / CONVERT(decimal(19,8),1750)
select (100.000/ 1750.000).
I would expect the first one to give me the most accurate result but the second query with a lower precision and scale returns a result with a greater scale.Thanx.

declare @x int, @y int, @f float
set @x = 100

set @f = @x / @y
print @x
print @y
print @f
in the above code @f prints as 0 instead of 0.05
how would i correct that?

Im using SQL Server 2000.
If i divide two integer column values, the result i am getting is integer. i.e
Update tblStudents SET Percentage=(AttendedClasses/TotalClasses);
AttendedClasses,TotalClasses are two column names(Integer). I hav declared Percentage column as float.
The result im getting is integer value..
I want the actual float value(i.e Percentage)
How to Resolve this??
Help me with this issue..
thanks in advance.
Hi - I have what seems like a simple problem and I cannot find an answer to it. I'm hoping someone here can help.
I want to divide 2 numbers but have the answer come back with no decimal places. I don't want to round up or down..just give me the whole number and drop the decimal places. For example:
Select units/60 as answer
And units = 280. I want the "answer" to be 4 and NOT 4.66.
Any ideas?
I'm on SQL server version 8.0.
Thanks in advance!

I have a function that divides the results of 2 seperate datafiffs to provide a ratio. For some reason I cannot get the result to return as a decimal - it is only giving me integers. I have tried cast and converting both the idividual numbers and the results, no luck. If I write the query on it's own, casting the one of the values as decimal will return the right value. Any ideas what I am missing? Here is the function:
Create function fn_FTE(
@tkpr varchar(5),
@start datetime,
@end datetime)
Returns decimal
Begin
declare
@fte decimal
select @fte =
sum(datediff(dd,
(case
when eedatebeg < @start then @start
else eedatebeg
end),
(case
when eedateend > @end then @end
when eedateend is null then @end
else eedateend
end))) /datediff(dd,@start,@end)
from vw_employ_dates
where
eedatebeg < @end
and (eedateend > @start or eedateend is null)
and eudescrip = @tkpr
return @FTE
end
thanks for any help!

I would like to have an either a sql statement (1st) or a stored procedure (2nd) that would give me the percent correct for each student on the test.
In Access I could cheat and use this:
Code BlockSELECT Students.StudentName,
Count(Students.StudentName) AS TotalCorrect,
(SELECT Count(QuizMaster.ID) FROM QuizMaster;) AS TotalQuestions,
([TotalCorrect])/([TotalQuestions])*100 AS PercentValue
FROM (Answers INNER JOIN Students
ON Answers.StudentID = Students.ID)
INNER JOIN QuizMaster
ON (Answers.Answer = QuizMaster.Answer)
AND (Answers.QuestionID = QuizMaster.ID)
GROUP BY Students.StudentName
ORDER BY Students.StudentName, PercentValue;
Which is composed of the following...
Code Block
SELECT Students.StudentName,
Count(Students.StudentName) AS TotalCorrect
FROM (Answers INNER JOIN Students
ON Answers.StudentID = Students.ID)
INNER JOIN QuizMaster
ON (Answers.Answer = QuizMaster.Answer)
AND (Answers.QuestionID = QuizMaster.ID)
GROUP BY Students.StudentName;
SELECT Count(QuizMaster.ID) AS TotalQuestions
FROM QuizMaster;
([TotalCorrect])/([TotalQuestions])*100 AS PercentValue
But... that wont fly in SQL Server...What would work without using temp tables?
What would be the EASIEST way to do this?
Another way someone suggested is:
Code BlockCREATE PROCEDURE GetStudentGradeByID @StudentID Integer
AS
BEGIN
DECLARE @TotalQuestionsAsked as Integer;
DECLARE @StudentName as VarChar(50);
DECLARE @QuestionsCorrect as Integer;
DECLARE @PercentCorrect as Float;
set @TotalQuestionsAsked = select COUNT(*)FROM QuizMaster;
set @StudentName = select StudentName from Students where ID = @StudentID;
set @QuestionsCorrect = select count(Answers.ID) from Answers LEFT JOIN QuizMaster on Answers.QuestionID = QuizMaster.ID where StudentID = @StudentID AND QuizMaster.Answer = Answers.Answer;
set @PercentCorrect = (CAST (@QuestionsCorrect AS FLOAT) / CAST (@TotalQuestionsAsked AS FLOAT)) * 100.0;
select @QuestionsCorrect as TotalCorrect, @StudentName as Student, @TotalQuestionsAsked as NumQuestions, @PercentCorrect as CorrectPct;
END
But I need this as a datasource for a datagrid that would show all students etc... so using a parameter isn't really what I want.
So... could a stored procedure work for this?
I am just learning SQL Server Express Edition and have been experimenting with various ANSI settings, etc. I think I may have accidentally set something incorrectly and don't know how to undo it. When I divide 3/2 I get 1.00 instead of 1.5.
I enter code:
DECLARE @special as decimal(3,2)
SET @special = 3/2
SELECT @special
The result comes back 1.00. Thanks for any help.
My function in my report, thu function I currently use is the following:
Public Function CalcDivision(ByVal Numerator As Object, ByVal Denominator As object, ByVal DivideByZeroDefault As Object) As Object
If Denominator <> 0 Then
  Return Numerator/Denominator
Else
  Return DivideByZeroDefault
End If
End Function
=Code.CalcDivision(Fields!Sales_Refund.Value,Fields!Sales.Value,Nothing)
The problem is that it still return zero instead of nothing, which is the goal here, I have tried different variation but still returning zero.
I've got two integer columns in the table, third one is computed by previous two ones division. That's fine, however sometimes can happen that divided by column is set to zero. How can i avoid division by zero exception, please? TIA

I m trying to create an analysis services project, I have the following system error : division by zero.
Then I€™ve tried to use the AdventureWorks analysis services project to see if I have also the same error , and yes I have the same error.
I live in Belgium, does the problem comes from the regional settings?
I€™ve tried to change them to English(United-States) and then I have this error : system error key not valid for use in specified state
I€™m only trying to execute the project, when I build everything goes fine.
