InterBase database의 쿼리를 실행하고, ibase_fetch_row(), ibase_fetch_object(), ibase_free_result()와 ibase_free_query()의 실행에 사용되는 식별자를 리턴한다.
참고: Although this function supports variable binding to parameter placeholders, there is not very much meaning using this capability with it. For real life use and an example, see ibase_prepare() and ibase_execute().
