在用powerdesigner生成的SQL语句建表时，不知怎么搞的在表名中加了个空格，没有在意直接在PL/SQL中运行了，发现的时候无论用语句还是直接右键删除都不好用。用drop命令删除会提示“ORA-00933：SQL命令未正确结束”，如果遇到这个问题可在表名上用“”引起来，再删就OK了。
但是我这个还是不行，加上引号后提示，“ORA-00604: 递归 SQL 级别 1 出现错误，ORA-01422: 实际返回的行数超出请求的行数”，解决这个的办法是用sys账户登录，然后执行delete from dual，可以先执行select * from dual，里边会有两个Y，然后执行delete语句后，，会自动保留一个Y，删除后再执行drop语句，表就可以删除了。
