Please see the documentation here:

You'll have something along the lines of (just a sketch, obviously):

typedef struct {
        sqlite3 *db;
        sqlite3_stmt *stmt;
} my_handle_t;

my_handle_t my_init() {
        sqlite3_open();
        sqlite3_prepare();
        return handle;
}

void my_exec(my_handle_t handle, int id) {
        sqlite3_bind_int();
        /* Put in a loop or whatever: */
        sqlite3_step();
        /* After you've gotten all the result rows: */
        sqlite3_reset();
}


Your caller would then call my_init() once to get a handle, then call
my_exec() a bunch of times using that handle.  The way your example is
doing it, _every_ time through the loop it does an exec(), which
re-compiles the same SQL code (which is not a fast operation).

There are plenty of other examples floating around on this mailing
list, I'm sure - just do some digging.
