INF: Using the NUMERIC_ROUNDABORT SET Option |
Q136468
Microsoft SQL Server version 6.0 has a new SET option to abort the
truncation of numeric values. The new option NUMERIC_ROUNDABORT specifies
the behavior following a loss of scale for an exact numeric type during
conversion. By default this option is OFF, allowing SQL Server to round the
numeric result and continue processing. When this option is ON, SQL Server
aborts the statement or query that caused the error.
This behavior was previously covered under the SET ARITHABORT option, which
did not allow you to abort the loss of most significant digits and ignore
the loss of least significant digits.
The SET NUMERIC_ROUNDABORT option does not allow the least significant digits (or the most significant digits) to be lost for an exact numeric type during conversion. For example, an attempt to insert a value with three digits after the decimal into a numeric datatype with scale two will complete successfully with the default setting NUMERIC_ROUNDABORT OFF, as in the following script:
use pubs
go
create table t1 (x numeric(6,2))
go
insert t1 values (1234.567)
go
With the option NUMERIC_ROUNDABORT ON, the insert will abort, as in the
following script:
use pubs
go
set numeric_roundabort on
create table t2 ( x numeric(6,2))
go
insert t2 values (1234.567)
go
