If you don't like the standard sql implementation, you could use plsql 
or any language to make an abstraction layer/wrapper for this 
functionality.  Just pass everything as a key/value pair, in an array or 
hashtable structure, to your abstraction layer/wrapper, and it can cycle 
through the data structure to do the insert or update for you.

In very rough psuedo-code, something like

    create my_data_structure {
           table = employees,
           first_name = sally,
           last_name = smith,
           date_of_birth = 2008-01-01

    call function mywrapper (my_data_structure)

          function cycles through array, and creates an sql string 

This may have problems with constraints, foreign keys, etc.
