Using embedded SQL.

Hello,
    I'm trying to learn embedded SQL in C. However, it's not working
and reading the documentation is not answering my question(s). Here is my
code:

#include <stdlib.h>
#include <stdio.h>
exec sql include sqlca;

int main( int argc, char *argv[] ) {

   exec sql whenever sqlerror sqlprint;
   exec sql connect tootle;
   exit( 0 );
   exec sql disconnect sprawlsr;
}

And here is what I get back:

sql error Could not connect to database <DEFAULT> in line 25.

What am I doing wrong? Yes, the database does exist as tootle.
