Arithmetic Overflow Error Converting Numeric To Data Type Numeric In Sql Server 2012
in some cases. The column has a datatype nvarchar . I am just interested in the places where its numeric where none numeric i dont need it. I use case like below (SELECT case when isnumeric(dia) =1 then dia else '' end as days from dbo.Debtor ) the above query works fine and return the record where is numeric and empty where is null. However, i want to return my records as decimal or float. I because i want to arithmetic overflow error converting numeric to data type numeric. the statement has been terminated be able to filter like SELECT ..... WHERE EXISTS( (SELECT case when isnumeric(dia) =1 then dia else '' end as days from dbo.Debtor ) > 0 ) The above is just an example but didnt tested. Please my Problem now is when i cast my column dia to decimal i get the error "Arithmetic overflow error converting nvarchar to data type numeric". Below is my query . (SELECT case when isnumeric(dia) =1 then cast(dia as decimal(3,1)) else 0 end as de from dbo.Debtor ) Please any help would be appreciated. Thank you sql sql-server share|improve this question edited Apr 3 '14 at 9:57 asked Apr 3 '14 at 9:32 Nuru Salihu 1,10131539 TRY_CONVERT function? –dean Apr 3 '14 at 9:41 Decimal(3,2) means largest number you can use is 9.99. Are you sure that's right for you and you don't have larger values in dia column? –Nenad Zivkovic Apr 3 '14 at 9:43 Sorry sir. its decimal(3,1). Thank you. –Nuru Salihu Apr 3 '14 at 9:57 1 ISNUMERIC returns 1 for a lot of things that will not fit in a decimal(3,1). Try with ISNUMERIC(dia + 'e0') = 1 AND LEN(dia) <= 5 AND ABS(CONVERT(decimal(6,1), dia))) < 100 –adrianm Apr 3 '14 at 12:23 Please can you explain the logic behind your query ? why do i need the len() and the ABS(CONVERT(decimal(6,1), dia))) < 100 ? pl

A numeric(3,2) can only hold up to 9.99. share|improve this answer answered Jan 13 '10 at 18:21 Joe 24k77194 You beat me to it. –HLGEM Jan 13 '10 at 18:22 add a comment| up vote 14 down vote Lets see, numeric (3,2). That means you have 3 places for data and two of them are to the right of the decimal leaving only one to the left of the decimal. 15 has two places to the left of the decimal. BTW if you might have 100 as a value I'd increase that to numeric (5, 2) share|improve this answer answered Jan 13 '10 at 18:21 HLGEM 67.8k665133 add a comment| up vote 10 down vote Precision and scale are often misunderstood. In numeric(3,2) you want 3 digits overall, but 2 to the right of the decimal. If you want 15 => 15.00 so the leading 1 causes the overflow (since if you want 2 digits to the right of the decimal, there is only room on the left for one more digit). With 4,2 there is no problem because all 4 digits fit. share|improve this answer answ
yankuik 2 Comments You've probably seen the following error: There are a few causes for this error, but basically, this error is telling us that what we are trying to http://www.yankuik.com/en/arithmetic-overflow-error/ convert is bigger (overflows) than the data type that we defined for that attribute. Let's ignore the requirements for now but for some reason we're storing numbers in an nvarchar attribute. Next, let's explain the problem, we have a source column/attribute and a target column/attribute, Source: it is an nvarchar(40) that stores numbers with long decimals, i.e. ‘699.934239999999999999999999999999999999' Target: it is an nvarchar(40) that stores numbers with error converting only 4 decimals, i.e. ‘699.9342' or numeric (18,4) So, in my mind, the solution looked like this: 1.-Convert the source value into numeric (18,4) as this was the requirement (we can store other data in this column, but if we store numbers, the client would like to format them as numeric (18,4)). 2.-Convert it back to nvarchar(40) already cleaned up, showing only 4 decimals. Easy right? WRONG! arithmetic overflow error Now, let's replicate the error, the problem that I was facing was that my code looked like this. declare @source nvarchar(40) = '699.934239999999999999999999999999999999' select @source select CONVERT( nvarchar(40),CONVERT(numeric(22,4),@source)) Error comes up: Basically SQL is trying to squeeze the 699.9342…… into the target data type, as we can see it is not automatically done, we need to workaround this and make it work. Googling a little bit, I found the SQL Function STR that returns a float to a char by defining the total lenght of that char and the number of decimals that you'd like to show from that float. Finally, I came up with the following: declare @source nvarchar(40) = '699.934239999999999999999999999999999999' select @source select ltrim(CONVERT( nvarchar(40),STR(cast (@source as float),22,4))) It worked, however I had to add the LTRIM function to clean all the extra spaces to the left given that it is a CHAR result. So, what do you think? Are there any other alternatives to this?
