ODBC provides data types and functions that help applications to interact with the database. Can you? The important difference between Order and Preference is that once a match is found the client MUST NOT consider records with a different Order but they MAY process records with the same Order but different Preferences. Openquery is performed on the server and it could be it's processing the rows much faster and is only returning one row over the network. The combination of NAPTR records with Service Records (SRV) allows the chaining of multiple records to form complex rewrite rules which produce new domain labels or uniform resource identifiers (URIs). DNS NAPTR Query . This could be another NAPTR, SRV or A record. The main difference between these queries is how easy it is to understand what is going on. Effective with Cisco IOS XE Release 2.5, the DNS SRV query used to determine the IP address of the user endpoint is modified in compliance with RFC 2782 (which supersedes RFC 2052).
