Oracle 数据库 SQL 开发人员 - 错误 - 删除 TABLE

Question

我创建了一个 table 并想删除 table，但我不断收到错误消息代码 ORA-00903，我正在使用管理员帐户。

Answer 1

使用以下键 drop 删除 table

drop table tablename

Answer 2

drop table“工程师”- 您已经创建了一个区分大小写的对象名称，或者有人创建了，现在您必须随时处理它。

在 Oracle 中创建东西时，最好不要引用对象名称。

create table "Engineers" (a integer); -- not a good practice in Oracle...for reasons you have already seen

drop table engineers;
drop table Engineers;
drop table ENGINEERS;
drop table "Engineers"; -- this will work

运行那 -

Table "Engineers" created.
