Arithmetic overflow error converting numeric to data type numeric

Question

I keep getting this error message everytime I run this query:

Msg 8115, Level 16, State 8, Line 33
Arithmetic overflow error converting numeric to data type numeric.
The statement has been terminated.

But if I change the create table to (7,0), I don't get the error message.But I need my data to be displayed as a decimal. I have tried 8,3 does not work.

DECLARE @StartDate AS DATETIME
DECLARE @StartDate_y AS DATETIME
DECLARE @EndDate AS DATETIME
DECLARE @temp_y AS DATETIME

SET @temp_y = Dateadd(yy, Datediff(yy, 0, Getdate()), 0)
SET @StartDate_y = Dateadd(dd, 1 - Datepart(dw, Dateadd("ww", -2, @temp_y)),
                                      Dateadd("ww", -2, @temp_y))
SET @StartDate = Dateadd(dd, 1 - Datepart(dw, Dateadd("ww", -2, Getdate())),
                                  Dateadd("ww", -2, Getdate()))
SET @EndDate = Dateadd(dd, 6, @StartDate)

Answer 1

If you want to reduce the size to decimal(7,2) from decimal(9,2) you will have to account for the existing data with values greater to fit into decimal(7,2). Either you will have to delete those numbers are truncate it down to fit into your new size. If there was no data for the field you are trying to update it will do it automatically without issues

Answer 2

I feel I need to clarify one very important thing, for others (like my co-worker) who came across this thread and got the wrong information.

The answer given ("Try decimal(9,2) or decimal(10,2) or whatever.") is correct, but the reason ("increase the number of digits before the decimal") is wrong.

decimal(p,s) and numeric(p,s) both specify a Precision and a Scale. The "precision" is not the number of digits to the left of the decimal, but instead is the total precision of the number.

For example: decimal(2,1) covers 0.0 to 9.9, because the precision is 2 digits (00 to 99) and the scale is 1.

decimal(4,1) covers 000.0 to 999.9
decimal(4,2) covers 00.00 to 99.99
decimal(4,3) covers 0.000 to 9.999

Answer 3

Use TRY_CAST function in exact same way of CAST function. TRY_CAST takes a string and tries to cast it to a data type specified after the AS keyword. If the conversion fails, TRY_CAST returns a NULL instead of failing.

Answer 4

check your value which you want to store in integer column. I think this is greater then range of integer. if you want to store value greater then integer range. you should use bigint datatype

Answer 5

(7,2) it means, variable will contain 5 digits before the decimal and 2 digits after decimal .if you are putting 7 digits before the decimal that is wrong.

Answer 6

My guess is that you're trying to squeeze a number greater than 99999.99 into your decimal fields. Changing it to (8,3) isn't going to do anything if it's greater than 99999.999 - you need to increase the number of digits before the decimal. You can do this by increasing the precision (which is the total number of digits before and after the decimal). You can leave the scale the same unless you need to alter how many decimal places to store. Try decimal(9,2) or decimal(10,2) or whatever.

You can test this by commenting out the insert #temp and see what numbers the select statement is giving you and see if they are bigger than your column can handle.

Answer 7

(4 rows affected)
Msg 8115, Level 16, State 8, Line 3
Arithmetic overflow error converting int to data type numeric.

This error will occur when inserting data is not matching with declared decimal data type in the table.

To resolve this error, you have to modify the decimal data type limit or modify the test data.

Answer 8

I approach these problems by trying to isolate the select statement.

Comment out fields until you can isolate which field is actually the problem.

Once you can say : Select from

you can then add Cast(field as numeric(4,6)) [tryMe]

This has the benefit of selecting N rows and then throwing the error. You can then take the cast off and see what value N+1 has.

The result is usually surprising... or you would not be reading this SO!

I had a problem today where I was calculating tax and had Numeric(7,4) The issue wound up being I had one order that owed 1000$ in tax.

Numeric(7,4) will only allow 3 digits to the left of the decimal. DOH!
