NumericPrecision Property

未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能，並規劃修改目前使用這項功能的應用程式。

The NumericPrecision property specifies the maximum number of digits in a fixed-precision, numeric data type.

語法

object
.NumericPrecision [= value]

Parts

  • object

  • value
    A long integer value from 1 through the value of the MaximumLength property (as returned by the SystemDatatype object referencing the base data type of the column or user-defined data type)

Data Type

Modifiable

Read/write

Prototype (C/C++)

HRESULT GetNumericPrecision(LPLONG pRetVal);
HRESULT SetNumericPrecision(long NewValue);
