This is not a true cursor-like behavior because, while the registry allows chunked retrieval of results, these results do not represent a frozen snapshot in time.

这并非一个真正的类似光标的行为，因为当注册中心允许结果的分块检索时，这些结果不代表及时的冻结快照。

A snapshot is an ODBC static cursor.

快照是一个ODBC静态游标。

Therefore, the snapshot is only as current as the cursor library's buffer.

因此，快照只与游标库的缓冲区一样新。
