SqlMethodAttribute Class
.NET Framework 3.0
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.
Namespace: Microsoft.SqlServer.Server
Assembly: System.Data (in system.data.dll)

/** @attribute SerializableAttribute() */ /** @attribute AttributeUsageAttribute(AttributeTargets.Method, AllowMultiple=false, Inherited=false) */ public final class SqlMethodAttribute extends SqlFunctionAttribute

Not applicable.
For a property, the SqlMethodAttribute should be used on the setter or the getter directly.
Inherits from a SqlFunctionAttribute.
The following example shows a UDT method that is attributed to indicate that the method will not be invoked on null instances of the type, that the method will not change the state of the type, and that the method will not be called when a null reference (Nothing in Visual Basic) parameters are supplied to the method invocation.
' Distance from Point to the specified x and y values method. <SqlMethod(OnNullCall:=False, IsMutator:=False, InvokeIfReceiverIsNull:=False)> _ Public Function DistanceFromXY(ByVal ix As Int32, ByVal iy As Int32) _ As Double Return Math.Sqrt(Math.Pow(ix - _x, 2.0) + Math.Pow(iy - _y, 2.0)) End Function
