会出现如下的一个错误:
ORA-12712: new character set must be a superset of old character set
对这个错误的解释是:
Cause: When you ALTER DATABASE ... CHARACTER SET, the new character set must be a superset of the old character set. For example, WE8ISO8859P1 is not a superset of the WE8DEC.
Action: Specify a superset character set.
除非目标字符集是原字符集的严格超集,比如从US7ASCII改到ZHS16GBK。 |
