Oracle also allows cursors to be tightly bound to a looping statement, a construct called a cursor FOR loop.
Oracle还允许将游标与一个循环语句紧密地绑定在一起,形成所谓的游标FOR循环结构。
That is because the export utility is bound with the cursor stability (CS) isolation level (for a description of the DB2 isolation levels, see the sidebar).
这是因为export工具被绑定为具有游标稳定性(CS)隔离级别(有关DB 2隔离级别的描述,请参阅侧栏)。
