SqlMethodAttribute Class
Indicates the determinism and data access properties of a method or property on a user-defined type (UDT). The properties on the attribute reflect the physical characteristics that are used when the type is registered with SQL Server.

Assembly: System.Data (in System.Data.dll)
The SqlMethodAttribute type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | SqlMethodAttribute | An attribute on a user-defined type (UDT), used to indicate the determinism and data access properties of a method or a property on a UDT. |
| Name | Description | |
|---|---|---|
![]() | DataAccess | Indicates whether the function involves access to user data stored in the local instance of SQL Server. (Inherited from SqlFunctionAttribute.) |
![]() | FillRowMethodName | The name of a method in the same class as the table-valued function (TVF) that is used by the TVF contract. (Inherited from SqlFunctionAttribute.) |
![]() | InvokeIfReceiverIsNull | Indicates whether SQL Server should invoke the method on null instances. |
![]() | IsDeterministic | Indicates whether the user-defined function is deterministic. (Inherited from SqlFunctionAttribute.) |
![]() | IsMutator | Indicates whether a method on a user-defined type (UDT) is a mutator. |
![]() | IsPrecise | Indicates whether the function involves imprecise computations, such as floating point operations. (Inherited from SqlFunctionAttribute.) |
![]() | Name | The name under which the function should be registered in SQL Server. (Inherited from SqlFunctionAttribute.) |
![]() | OnNullCall | Indicates whether the method on a user-defined type (UDT) is called when nullptr input arguments are specified in the method invocation. |
![]() | SystemDataAccess | Indicates whether the function requires access to data stored in the system catalogs or virtual system tables of SQL Server. (Inherited from SqlFunctionAttribute.) |
![]() | TableDefinition | A string that represents the table definition of the results, if the method is used as a table-valued function (TVF). (Inherited from SqlFunctionAttribute.) |
![]() | TypeId | When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.) |
| Name | Description | |
|---|---|---|
![]() | Equals | Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Returns the hash code for this instance. (Inherited from Attribute.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | IsDefaultAttribute | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.) |
![]() | Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | _Attribute::GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |
![]() ![]() | _Attribute::Invoke | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |
For a property, the SqlMethodAttribute should be used on the setter or the getter directly.
SqlMethodAttribute inherits from a SqlFunctionAttribute, so SqlMethodAttribute inherits the FillRowMethodName and TableDefinition fields from SqlFunctionAttribute. Note that it is not possible to write a table-valued method, although the names of these fields might suggest that it is possible.
