1. CONVERT:用于转换字符串的字符集。 用法:CONVERT(string, destination_character_set, source_character_set) 示例:SELECT CONVERT('你好', 'UTF8', 'AL32UTF8') FROM dual; 2. NLS_CHARSET_ID:返回给定字符集名称的标识。 用法:NLS_CHARSET_ID(character_set_name) 示例:SELECT NLS_CHARSET_ID('UTF8'...
CONVERT(string, destination_character_set, source_character_set) 其中: string是要转换的字符串。 destination_character_set是目标字符集。 source_character_set是原始字符集。 下面是一个使用CONVERT函数的示例: SELECT CONVERT(‘Hello, 世界!’, ‘UTF8’, ‘ZHS16GBK’) FROM DUAL; 这个例子将字符串’Hell...
The following example illustrates character set conversion by converting a Latin-1 string to ASCII. The result is the same as importing the same string from a WE8ISO8859P1 database to a US7ASCII database. SELECT CONVERT('Ä Ê Í Ó Ø A B C D E ', 'US7ASCII', 'WE8ISO88...
在Oracle中,CONVERT函数用于将一个字符串从一种字符集转换为另一种字符集。这个函数通常用于处理在不同字符集之间转换时可能出现的问题,比如在数据库中存储的字符集与应用程序使用的字符集不一致时。CONVERT函数的语法如下: CONVERT(string, destination_character_set, source_character_set) 复制代码 其中,string是要...
