属性

	名称	说明
	DataType	Gets the scalar data type. （从 IScalar 继承。）
	IsAggregateFunction	Gets a value that indicates whether this is an aggregate function. （从 IScalarFunction 继承。）
	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. （从 IMetadataObject 继承。）
	Nullable	Gets a Boolean value that indicates whether the scalar object is nullable. （从 IScalar 继承。）
	Parameters	Gets a collection that contains the parameters that the function or module accepts. （从 IFunctionModuleBase 继承。）
