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。) | |
ScalarType | Gets the scalar type. (从 IScalar 继承。) |
