当我尝试在 PL/SQL 过程中创建表时，为什么会收到 PLS-00103？

Question

我收到此错误：

[Error] PLS-00103 (23: 9): PLS-00103: Encountered the symbol "CREATE" when expecting one of the following: begin case declare exit for goto if loop mod null pragma raise return select update while with <an identifier>

尝试运行此代码时。我在这里做错了什么？
我应该使用批量收集吗？如果是这样，如何？

如您的问题所示，您不能直接在 PL/SQL 块中编写 DDL。

但是，您可以使用EXECUTE IMMEDIATE如下所示的命令执行这些 DDL 。

  CREATE OR REPLACE PROCEDURE ddl_test AS
  BEGIN
  EXECUTE IMMEDIATE 'DROP TABLE tbl1';
  END;
  /
