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.

Arithmetic overflow error occurred converting expression to data type bigint when I am applying cast function on a 60 digit number.
The largest positive value which BIGINT can store is 2^63-1, which is roughly 1x10^18. Using DECIMAL or NUMERIC would get you larger storage, up to 1x10^38. But neither can accommodate 60 digits of precision.
You might want to ask yourself whether you really need to maintain so much precision for a large number as this.
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 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 am getting this error
Arithmetic overflow error converting float to data type numeric
when I try to run my view but not sure what am I doing wrong with my calculation. I have researched but could not solve it so far.
Here is the line of code that is causing the error:
ISNULL(CAST(CAST(TOTAL_APPTS.APPT_CNT AS FLOAT) / TOTAL_RECS.PAT_CNT AS NUMERIC(3, 2)), 0) AS [CONVERSION RATE]
Your precision and scale arguments to NUMERIC are very small. Have you tried increasing those? Your numeric value can only handle numbers up to 9.99.
You should peruse this page:
decimal and numeric (Transact-SQL)
It's too much to explain here, but basically the first argument (precision) is the max number of digits (in your case 3) and the second argument (scale) is the number of digits to the right of the decimal point, which always takes away from the number of digits you can have to the left of the decimal point. So in your case, 3-2 = 1 digit allowed to the left of the decimal point, which is why your max value can only be 9.99.
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
