Remarks

A SqlRuleFilter holds a SQL-like condition expression that is evaluated in the broker against the arriving messages' user-defined properties and system properties. All system properties (which are all properties explicitly listed on the ServiceBusMessage class) must be prefixed with sys. in the condition expression. The SQL subset implements testing for existence of properties (EXISTS), testing for null-values (IS NULL), logical NOT/AND/OR, relational operators, numeric arithmetic, and simple text pattern matching with LIKE.
