我的 Oracle 语法有什么问题？
What is wrong with my Oracle syntax?
我有一个 SQL 存储过程需要转换为 Oracle。我在语法上遇到了一些麻烦。
我得到的当前错误是：
Error(75,1): PLS-00103: 遇到符号 "DROP" 期望以下之一: ( begin case declare end exception exit for goto if loop mod null pragma raise return select update while with << continue close current delete fetch lock insert open rollback savepoint set sql execute commit forall merge pipe purge
我想我还有很多。谁能帮我弄清楚我做错了什么？

您几乎肯定不想在 Oracle 过程中创建和删除 table。 Oracle 临时 table 与 SQL 服务器临时 table 非常不同。在 SQL 服务器中，临时 table 的定义在会话本地（假设 table 名称以 # 为前缀）。 Oracle 没有这种本地临时文件的概念 table。 Oracle 中的临时 table 是全局的——定义对所有会话可见，数据仅对本地会话可见。这意味着您将在定义永久 tables 的同时在您的过程之外创建一次临时 tables-- 并且您不会将它们丢弃在过程中.

当然，在 Oracle 中，首先使用临时 tables 是非常不常见的——做一个直接的端口并在 Oracle 中为每个使用它们的过程使用临时 tables在 SQL 服务器中将创建一些非常非惯用的 Oracle 代码，这些代码的效率可能会低于预期。在您的系统中最终出现成百上千个临时 table 也可能很烦人，尤其是当不同的 SQL 服务器程序创建具有相同名称和不同列集的临时 table 时。使用本地集合或简单地不首先具体化数据并直接查询底层永久性 table 可能会更好地为您服务。这取决于您为什么首先在 SQL 服务器中使用临时 tables。例如，请参阅 alternatives to temporary tables.
