 ## v4.3.19
 
 ### Bug fixes
+
 - Fix GET `/auth_clientid` and `/auth_username` counts. [#8655](https://github.com/emqx/emqx/pull/8655)
+- Fix rule SQL compare to null values always returns false. [#8743](https://github.com/emqx/emqx/pull/8743)
+  Before this change, the following SQL failed to match on the WHERE clause (`clientid != foo` returns false):
+  `SELECT 'some_var' as clientid FROM "t" WHERE clientid != foo`.
+  The `foo` variable is a null value, so `clientid != foo` should be evaluated as true.
