pl/sql的综合运用上例用到的oracle里关于游标的几个内置函数:％isopen,％notfound,％rowcount。 隐式游标更多用在for loop中，你不用再手工去open，fetch或是close游标，非常方便-pl/sql integrated the use of oracle used in Example cursor on several built-in functions: isopen, notfound, rowcount. Implicit cursor more used in for loop, you no longer have to manually open, fetch or close the cursor, a very convenient
