一般都用CBLOB存的。A CLOB (character large object) value can be up to two giga-characters long. A CLOB is used to store unicode character-based data, such as large documents in any character set.The length is given in number characters for both CLOB, unless one of the suffixes K, M, or G is given, relating to the multiples of 1024, 1024*1024, 1024*1024*1024 respectively.Length is specified in characters (unicode) for CLOB.
UNICODE变长字符串,pl/sql类型,最大宽度为32767bytes,但作为字段的类型,最大宽度为2000bytes

可以建一个NCLOB字段
从原来的NVARCHAR2字段中select 出数据,再insert到新的字段中。
是不是发布文章的时候先在程序上面把它分成几段然后再插入到几个字段里?然后读取的时候再一起select出来?
