The IScalarValuedFunction type exposes the following members.

Properties

  Name Description
Public property BodyText Gets the Transact-SQL string that defines the module. (Inherited from IUserDefinedFunction.)
Public property DataType Gets the scalar data type. (Inherited from IScalar.)
Public property ExecutionContext Gets the IExecutionContext object that specifies the module execution context. (Inherited from IUserDefinedFunctionModuleBase.)
Public property IsAggregateFunction Gets a value that indicates whether this is an aggregate function. (Inherited from IScalarFunction.)
Public property IsEncrypted Gets a value that indicates whether the module is encrypted. (Inherited from IUserDefinedFunctionModuleBase.)
Public property IsQuotedIdentifierOn Gets a Boolean value that indicates whether the unique identifier option is on. (Inherited from IUserDefinedFunction.)
Public property IsSchemaBound Gets a value that indicates whether the user-defined function is bound to a schema. (Inherited from IUserDefinedFunction.)
Public property IsSqlClr Gets a value that indicates whether this is a CLR module. (Inherited from IUserDefinedFunction.)
Public property IsSystemObject Gets a value that indicates whether this is a system object. (Inherited from IDatabaseObject.)
Public property ModuleType Gets the module type. (Inherited from ICallableModule.)
Public property Name Gets the name of the metadata object. (Inherited from IMetadataObject.)
Public property Nullable Gets a Boolean value that indicates whether the scalar object is nullable. (Inherited from IScalar.)
Public property Parameters Gets a collection that contains the parameters that the function or module accepts. (Inherited from IFunctionModuleBase.)
Public property Parent Gets the IDatabaseObject object that is the parent of this object. (Inherited from IDatabaseObject.)
Public property ReturnsNullOnNullInput Gets a value that indicates whether to call the function if at least one of the function arguments is null.
Public property ReturnType Gets the scalar data type of the module return value. (Inherited from ICallableModule.)
Public property ScalarType Gets the scalar type. (Inherited from IScalar.)
Public property Schema Gets the ISchema object that owns this object. (Inherited from ISchemaOwnedObject.)
