Getting int values from SQLite

Question

I heard of using sqlite3_prepare_v2 instead of sqlite_exec to get integers from database, but I failed to find any examples. This page wasn\'t help

Answer 1

After sqlite3_prepare has succeeded, you must not forget to clean up the statement with sqlite3_finalize. To get the result records, call sqlite3_step until it does not return SQLITE_ROW. To get the values of the current result record, call the sqlite3_column_* functions:

sqlite3_stmt *stmt;
if (sqlite3_prepare_v2(db, "SELECT 42", -1, &stmt, NULL) != SQLITE_OK)
    ...error...
else {
    for (;;) {
        int rc = sqlite3_step(stmt);
        if (rc == SQLITE_DONE)
            break;
        if (rc != SQLITE_ROW) {
            ...error...
            break;
        }
        printf("value: %d\n", sqlite3_column_int(stmt, 0));
    }
    sqlite3_finalize(stmt);
}
