为什么我不能在 sql server 表中插入小数？

Question

I have a simple query:

INSERT INTO tblIndicators (RunID, EventTS, MA1t3) 
Values (65, '11/2/2012 2:25:00 AM', 1.0); 

I get this error message:

Msg 8115, Level 16, State 8, Line 1
Arithmetic overflow error converting numeric to data type numeric.

The precision on the Decimal datatype is (8,8) . So whats the problem??

Answer 1

decimal (8, 8) means all 8 of your significant digits are to the right of the decimal point. 1.0 is too big.

Answer 2

Try decimal (8,2)

(8,8) doesn't leave you with any digits to the left of the .

Answer 3

8,8 means can store at maximum 0.99999999 if you need to store a number like 12345678.12345678 you should declare : decimal (16,8)

Explaining this declaration : decimal ( {TotalDigits} , {DigitsToTheRight} )
