	名稱	說明
	DataType	Gets the scalar data type. (繼承自 IScalar。)
	IsAggregateFunction	Gets a value that indicates whether this is an aggregate function. (繼承自 IScalarFunction。)
	IsDatePartFunction	Gets a value that indicates whether the function is a date-and-time parts function (for example, DATEDIFF, DATEPART, and so on).
	IsGlobalVariable	Gets a value that indicates whether this is a system function that starts with two at signs (@@) (for example, @@IDENTITY).
	IsVarArg	Gets a value that indicates whether the number of arguments is variable.
	MaxNumberOfArgs	Gets the maximum number of arguments that the function accepts.
	MinNumberOfArgs	Gets the minimum number of arguments that the function accepts.
	Name	Gets the name of the metadata object. (繼承自 IMetadataObject。)
	Nullable	Gets a Boolean value that indicates whether the scalar object is nullable. (繼承自 IScalar。)
	Parameters	Gets a collection that contains the parameters that the function or module accepts. (繼承自 IFunctionModuleBase。)
