IT depends on your needs. You may find some reasons here:

and 

http://gnade.sourceforge.net/

as to what you want.

You might want to consider the ways to query RDBs.
For example, GNADE has embedded SQL (which AFAIK is a standardised
mechanism) in addition to ODBC and native bindings,
and corresponding translators. 
The desired flexibility of your query statements at run time might
be orienting as well. If, for the sake of an extreme example, your
application reads SELECT statements from input and executes this
query, spitting out the results in text form, embedded SQL might
not be the first choice.
On the other hand, embedded SQL might force you to think about where
you are going to store items in your program, and at the same time
document the choices in place.
