SQL Server cast fails with arithmetic overflow
- by Jamie Ide
According to the entry for decimal and numeric data types in SQL Server 2008 Books Online, precision is:
p (precision)
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.
However, the second select below fails with "Arithmetic overflow error converting int to data type numeric."
SELECT CAST(123456789 as decimal(9,0))
SELECT CAST(123456789 as decimal(9,1))
