问题
I am working on an ASP.NET C# accounting app and I am in the transition from using floats/doubles to using decimals to represent money.
Now I want to control when and where rounding takes place. The way I understand it, SQL server rounds decimal data types differently than C# does.
Is there some way to get SQL server (2008) to warn or fail if decimal values (or any kind of data) are getting truncated or rounded?
Thanks,
回答1:
Look at SET NUMERIC_ROUNDABORT and the table with SET ARITHABORT
This determines whether nothing or something happens. The something (an error or warning) depends on SET ARITHABORT. However, you get NULL for a warning.
I'd consider doing your calculations in the client code, or use a wide decimal (eg 38,20) to mitigate it
