There is no native function compiled into the server that will pull out
just certain fields from a dump like that. However, you can manually
extract any part of any string through judicious use of the string
functions that are built in.

Depending on your version, you could create either a User-defined function
(UDF), a SQL Function, or a SQL Stored Procedure to help you do this.
