更正以下查询以sqlplus模式运行

当我在shell脚本中传递此查询并通过sqlplus模式执行时，我收到一个错误，指出行数太多，因此无法执行，我们可以将查询更改为行数较少吗？

是否必须为1个查询？您得到的确切错误消息是什么？你的问题-不要在评论中发布代码或附加信息。我认为“优化”不是正确的词，特别是因为这个问题与DB有关。你只有22行。我刚刚运行了一条1733行的SQL语句。很好。无论您使用什么方法将SQL传递给SQLPLUS，这都是您的限制。你需要修正这一点，因为22行对于一个查询来说并不多。你是不是将整个内容作为一行传递，然后得到SP2-0027：输入太长>2499个字符-忽略行？你发布的内容略高于该限制。当然，我们不应该猜测——为什么不在您的问题中显示您得到的实际错误和您的shell脚本呢？
