I have a variable of type decimal(26,16) and i want to save a value with 12 digits before decimal point and 14 digits after it, but it raises an "Arithmetic overflow error converting numeric to data type numeric". when i define a variable of this type, what does it really mean? it means it can only store values with 10 digits before and 16 digits after decimal point respectively or something else?
The highest number you can have in a decimal(26,16) is 9999999999.9999999999999999.
So when you try to store a 12 digit number it will to overflow
Try a decimal(28,16) instead
The maximum total number of decimal digits that can be stored, both to the left and to the right of the decimal point. The precision must be a value from 1 through the maximum precision of 38. The default precision is 18.
precision means the maximum number of digit you can use.
scale means the maximum number of digit you can use after decimal(.)

I have a double type column in impala
while I am trying to cut it upto some decimal places
I got this error
ERROR: AnalysisException: No matching function with signature: truncate(DOUBLE, TINYINT).
e.g select truncate(cast(0.4893617021276596 as double),7);
any workaround will be welcome
You can use round():
select round(col, 6)
If you actually want a truncate, then subtract 0.0000005:
select round(col - 0.0000005, 6)
Using the DECIMAL type, it is possible to represent numbers with greater precision than the FLOAT or DOUBLE types can represent.
The maximum allowed precision and scale of the DECIMAL type are both 38.
Precision is the total number of digits, regardless of the location of the decimal point.
Scale is the number of digits after the decimal place.
To represent the number 8.54 without a loss of precision, you would need a
DECIMAL type with precision of at least 3, and scale of at least 2.
Example:
Note that the DECIMAL(17,16) type means there is a total of 17 digits, with 16 of them after the decimal point.
DECIMAL(17,16) 3.1415926535897932
You could ALTER your table with DECIMAL type as follow:
ALTER TABLE my_table CHANGE field field DECIMAL(precision, scale);
or as suggest #Gordon Linoff, you could use round() function.
I'm converting a decimal value with has more than precision which I am converting to
select convert(numeric(8,4),17597.9)
I need to convert this value what is the alternative
The problem is not the precision of the value, but the scale.
The documentation says:
s (scale):
The number of decimal digits that are stored to the right of the decimal point. This number is subtracted from p to determine the maximum number of digits to the left of the decimal point. Scale must be a value from 0 through p, and can only be specified if precision is specified. The default scale is 0 and so 0 <= s <= p. Maximum storage sizes vary, based on the precision.
You've specified a datatype of precision 8, scale 4 - which means that you can have at most 8 digits total, with 4 digits to the right of the decimal point - and by extension of that, a max of 4 digits to the left.
If you want to convert that number, you'll need a to specify a precision p >= s + 5, such as numeric(9,4)
select convert(numeric(9,4),17597.9)
-- 17597.9000
I would like to remove zeros after two decimal places in DB2. I have more than 1000 rows for this column
For example
3.6900 needs to be converted to 3.69
I used cast in the query after my research and it gave me the correct result but I would like to understand what is DECIMAL(12,2) and how does this work ? Is there any better way to eliminate zeros?
SELECT CAST(CG.RATE AS DECIMAL(12,2)) AS test from fd.OFFERS CG
Please let me know.
what is DECIMAL(12,2) and how does this work?
The DECIMAL data type represents numbers with a specified decimal precision. You can read a description of the numeric data types:
A DECIMAL number is a packed decimal number with an implicit decimal point. The position of the decimal point is determined by the precision and the scale of the number. The scale, which is the number of digits in the fractional part of the number, cannot be negative or greater than the precision. The maximum precision is 31 digits.
i am having hard time determining the length of a Decimal data type. The data i have in column is like 0.08,1.2,12.35,121.36. Now if i go for (2,2) it throws an error : Arithmetic overflow error converting numeric to data type numeric. Just wondering should it be (6,2)? and if yes can anybody tell me Why 6 and 2?
In syntax like
NUMERIC(precision, scale)
precision is the total number of digits (count digits on both sides of the decimal point), and scale is the number of digits to the right of the decimal point.
From your examples, should be NUMERIC(5,2) - meaning five numbers in total and 2 after the decimal point.
I have a column which has decimal value of 18,8. I was asked to extend it to 18,18 to hold more places after ,.
ALTER TABLE [dbo].[TransakcjeGotowkowe]
ALTER COLUMN TransakcjeGotowkoweKwota decimal (18,18) NULL
Msg 8115, Level 16, State 8, Line 1
Arithmetic overflow error converting numeric to data type numeric.
The statement has been terminated.
I have also tried to do it by GUI. Nothing else changes just want to hold more data after ,.
Is there other way to do this ?
The Decimal datatype is made up of (precision, scale)
Precision is the total number of digits to the left AND the right of the decimal point.
Scale is the number of digits to the right of the decimal point.
If you want to increase the number of digits to the right to 18 you will need to increase the overall precision. In your case increase it by 10.
So you will need decimal(28,18)
MSDN Article on Precision & Scale
You would need to change it to 28,18 Your current column allows 10 digits to the left of the decimal point.
Changing it to 18,18 would only allow a range between +/-0.999999999999999999
