The callback interface will stay around. The newer interface is more
flexible. You can use it to build a callback interface, but you can
also make other structures and re-use compiled SQL. In fact if for some
reason the callback API disappeared you could rebuild it with
prepare/bind/reset instructions.

John,
Understood.
Is the callback function interface going to be eliminated?
What advantages does the new interface offer over the callback function
interface?

The callback interface is there to support legacy applications. It has
been replaced by prepare/step for new work.

Dennis,
Are you certain that the callback function interface has been
deprecated?
From the link you posted:
---------------
"2.2 Executing SQL statements
typedef int (*sqlite_callback)(void*,int,char**, char**);
int sqlite3_exec(sqlite3*, const char *sql, sqlite_callback, void*,
char**);
The sqlite3_exec function works much as it did in SQLite version 2. Zero
or more SQL statements specified in the second parameter are compiled
and
executed. Query results are returned to a callback routine."
---------------
I couldn't find a reference to its deprecation.

That's what I used to build all my code from
Stephen,
The quickstart code is very old. It uses the callback function interface
which is a depreciated API function that is maintained primarily for
backward compatibility.
You should really look at the prepare/bind/step/column set of API
functions introduced in version 3 which is described at
http://www.sqlite.org/capi3.html
