我在pl/sql块中写了一个光标.如果它有更多记录,这个块需要花费很多时间.如何在没有光标的情况下写这个或者是否有其他可以减少时间的替代方法？是否有任何替代查询来执行插入到一个表并使用单个查询从另一个表中删除？

我想设置一个沙盒环境来磨练我的pl/sql和数据库技能.我正在考虑下载完整版的Oracle 11G并使用SQL Developer.设置测试数据库并从那里开始工作.
有什么建议？你认为这是一个好方法吗？
先感谢您!
我在PL SQL上很新,当我尝试写下面的代码时:
BEGIN FOR foo IN (SELECT A, B, C FROM foo_table WHERE some_conditions) LOOP
DBMS_OUTPUT.PUT_LINE('sth here')
END LOOP;
在SQL Developer中执行statment时出现以下错误
当期望是以下一个时遇到符号"文件结束":开始案例声明结束例外以及更多...
我的陈述有什么问题？任何人都可以给我一个提示如何解决这个问题？所有提示我都会很高兴.
我怎样才能使用相同的文件(如ABC.txt)来编写UTL_FILE.
目前正在发生的事情是,当我试图写上ABC.txt一个条目被删除或替换为最新条目.我希望我所有的参赛作品都在场.我使用的是Oracle 10 g PL/SQL.
我有一个名为logger(message)的存储过程,其中message的类型为varchar2.
当我执行时
exec logger('hello');
它表示匿名块已完成,此过程的作用只是在另一个表中插入记录.
但是,当我用它作为脚本的一部分说:
Begin

IF (countCol <> 0) then
