dynamic cursor

基本解释

The ODBC Cursor Library is a dynamic-link library (DLL) that resides between the ODBC Driver Manager and the driver.
ODBC 游标库是一个驻留在 ODBC 驱动程序管理器和驱动程序之间的动态链接库（DLL）。
Sensitive cursors are the preferred scrollable cursor model for dynamic situations when the application cannot afford to buffer the data from an insensitive cursor.
当程序无法像Scroll-Insensitive型光标一样提供足够缓存时, Scroll-Sensitive型光标可以被替代用来作为动态的可滚动的光标.
A sensitive cursor provides a dynamic view of the underlying data, whereas an insensitive cursor generally isn't sensitive to any changes made to the database while the cursor is open.
敏感游标将提供底层数据的一个动态视图，而不敏感游标通常对游标打开时数据库的变化不敏感。
