JScript supports the use of structures, but not the declaration of new ones.
Any non-zero value is interpreted as 1.
The key difference between a SqlBoolean structure and a standard Boolean value is that, where a standard Boolean has two possible values, true and false, a SqlBoolean structure has three possible values, True, False, or Null.
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
