Then that implies that the mysql function call is returning
the same string value.

GTK uses GLists quite often, it may be good or bad depending
on the individual. But GTK uses GLists quite often so its
important to understand them.

If you have a function that returns a different string on
each call, then you'll want to do it like this:

const gchar *cstrptr;
GList *glist = NULL;

cstrptr = mysql_get_string(handle);
while(cstrptr != NULL)
{
 glist = g_list_append(glist, g_strdup(cstrptr));
 cstrptr = mysql_get_string(handle);
}

/* Now add the glist to the combo box here, the GtkCombo makes a copy
 * of the list internally so its no longer needed after this call.
 */
gtk_combo_set_popdown_strings(combo, glist);

/* Don't forget to deallocate the glist! */
g_list_foreach(glist, (GFunc)g_free, NULL);
g_list_free(glist);
glist = NULL;
