Calling oci_fetch_row() is identical to oci_fetch_array() with OCI_NUM flag and returns the next row from the result data as a numeric array.
注: 本函数对 PHP NULL 值设定 NULL 字段。
Subsequent calls to oci_fetch_row() will return the next row from the result data or FALSE if there is no more rows.
See also oci_fetch_array(), oci_fetch_object(), oci_fetch_assoc() and oci_fetch_all().
