Oracle Database 11g SQL 开发指南学习笔记：运行store_schema.sql时报错的问题

来源：互联网发布：mac下web开发工具编辑：程序博客网时间：2024/05/01 19:29

今天在按照书上的说明，运行这本书的代码store_schema.sql时报错了，主要有2个问题：

1、在插入数据时，报错：无效的月份，后来在晚上查了一下，主要是因为插入语句中的日期中的月份是英文的，比如1月就是JAN，另外，需要日期格式是"日-月-年"，所以在代码中加上了如下的语句：

alter session set nls_date_format='DD-MON-YYYY';alter session set nls_date_language='american';

这样就不会再报错了。

2、另外，在本地机器上直接运行代码store_schema.sql时，不会报错，但如果从一台远程的机器上执行这个脚本时，则好报错，本地的机器是oracle 11g 11.2.0 .1，而远程的机器安装的是oracle 10g 10.2.0.1，每次都报：对象每次已存在。

照理在代码中会删除已经最在的用户store的表：

DROP USER store CASCADE;

但还是报这种错误，一会是对象已存在，一会是报主键冲突，说插入了重复数据。

最后发现是由于代码中有一个connect语句：

CONNECT store/store_password;

所以，导致直接连接到了本地的oracle 10g的实例上去了，而上面已经创建了相应的对象，也就是通过使用oracle 10g的sqlplus，连接到远程的oracle 11g，然后删除 oracle 11g的实例上的用于store，再次创建这个用户store、授权等，然后接下去再次连接到store用户，但连接到的是本地的oracle 10g的实例，所以只要把代码修改成下面就可以了：

CONNECT store/store_password@192.168.1.104/orcl;

store_schema.sql的完整代码：
