见到有人问关于中文表名的导入导出问题,随手作了一个实验。链接:https://www.eygle.com/archives/2005/10/chinese_tablename_exp_imp.html
其实我从不推荐使用中文表名,因为可能在导入导出、字符集设置、应用显示等方面存在问题,要想正确解决面对的所有问题,必然需要对Oracle相关知识具有相当的了解,否则只是徒增困扰而已。
这个实验之前,只是见过别人使用中文表名、字段名等,自己却是第一次尝试,万事都有第一次么。
1.用中文名建立一个测试表
SQL> create table 测试 as select username from dba_users; Table created. Elapsed: 00:00:00.08 SQL> select * from 测试; USERNAME ------------------------------ SYS SYSTEM OUTLN EYGLE CSMIG TEST REPADMIN SCOTT ... DBSNMP WMSYS 13 rows selected. Elapsed: 00:00:00.00 |
2.exp导出数据
导出的时候需要注意客户端的字符集设置
[oracle@jumper oracle]$ exp eygle/eygle file=a.dmp Export: Release 9.2.0.4.0 - Production on Tue Oct 18 10:58:24 2005 Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved. Connected to: Oracle9i Enterprise Edition Release 9.2.0.4.0 - Production With the Partitioning option JServer Release 9.2.0.4.0 - Production Export done in ZHS16GBK character set and AL16UTF16 NCHAR character set About to export specified users ... . exporting pre-schema procedural objects and actions . exporting foreign function library names for user EYGLE . exporting PUBLIC type synonyms . exporting private type synonyms . exporting object type definitions for user EYGLE About to export EYGLE's objects ... . exporting database links . exporting sequence numbers . exporting cluster definitions . about to export EYGLE's tables via Conventional Path ... . . exporting table PLAN_TABLE 0 rows exported . . exporting table T1 5 rows exported . . exporting table T2 13 rows exported . . exporting table 测试 13 rows exported . ... Export terminated successfully without warnings. |
3.drop掉测试表
4.imp导出数据
5.验证数据无误
那么看来只要设置正确,也没有什么问题。

4.imp导出数据
[oracle@jumper oracle]$ imp eygle/eygle file=a.dmp tables=测试 Import: Release 9.2.0.4.0 - Production on Tue Oct 18 10:59:03 2005 Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.

5.验证数据无误
SQL> select * from 测试; USERNAME ------------------------------ SYS SYSTEM OUTLN EYGLE CSMIG TEST ... WMSYS 13 rows selected. Elapsed: 00:00:00.01 SQL> |

如果没有特殊的需要,
还是不想把事情复杂化
看來沒什麼問題嘛

是的,运气好的时候没有什么问题;运气不好的人就会遇到一堆问题了:)
我们的医院系统全是中文表名和字段名.其实也没有遇到什么问题.
无问题来源于深入全面的认知.
