Describes the type of access to system data for a user-defined method or function.

This enumeration is used in SqlMethodAttribute and SqlFunctionAttribute to indicate what type of access to system data the method or function has.

Note that methods and functions are not allowed to make changes to the database, so the options for this enumeration are None (meaning no data-access performed by the method or function) and Read (meaning that the method or function performs read-only data-access operations, such as executing SELECT statements).
