修改Oracle字符集(character set) 本方法适用于Oracle9i, 10g以及XE. 在10.2.0.1.0下测试无错. 需要注意的是, 使用此方法会破坏数据库中的原有双字节字符. 一种办法是先将数据库导出, 修改完字符集后再导入; 另一种办法就是不管他, 就那样使用. 一般如果是一个测试环境, 像方法二那样就可以了, 但是可能某些...

我们看到这个过程和之前ALTER DATABASE CHARACTER SET操作的内部过程是完全相同的,也就是说INTERNAL_USE提供的帮助就是使Oracle数据库绕过了子集与超集的校验. 这一方法在某些方面是有用处的,比如测试;应用于产品环境大家应该格外小心,除了你以外,没有人会为此带来的后果负责。
ORACLE数据库有国家字符集(national character set)与数据库字符集(database character set)之分。两者都是在创建数据库时需要设置的。国家字符集主要是用于NCHAR、NVARCHAR、NCLOB类型的字段数据,而数据库字符集使用很广泛,它用于:CHAR、VARCHAR、CLOB、LONG类型的字段数据; ...
