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。
If your driver already supports static cursors, you do not need to load the cursor library to get snapshot support.
如果驱动程序已经支援静态资料指标,就不需要载入资料指标程序库来取得快照集支援。
Snapshot support is based on the ODBC Cursor Library, which provides static cursors and positioned updates (needed for updateability) for any Level 1 driver.
快照集支援是ODBC 资料指标程式库架构,可提供静态资料指标和定位更新 (可更新性所需)给任何层级1 驱动程式。
