将数值转换为数值类型的算术溢出错误

Question

I have executed this query on 2 different databases:

Update table1 set PresencePayFactor = cast(30 as decimal (4,2))/ 30

it is working on one but not on the other. the 2 databases are sql server 2008 R2

it is giving the following error "Arithmetic overflow error converting numeric to data type numeric."

What may be the problem?

Answer 1

Is NUMERIC_ROUNDABORT set differently between the two?

SET NUMERIC_ROUNDABORT OFF
GO
Declare @TestTable Table ( PresencePayFactor decimal(4,2) null )
Insert @TestTable( PresencePayFactor )
Select Cast( 30 As decimal(4,2) ) / 30
GO
-- No error

SET NUMERIC_ROUNDABORT ON
GO
Declare @TestTable Table ( PresencePayFactor decimal(4,2) null )
Insert @TestTable( PresencePayFactor )
Select Cast( 30 As decimal(4,2) ) / 30
-- Arithmetic overflow error converting numeric to data type numeric.

SET NUMERIC_ROUNDABORT (Transact-SQL)
