Oracle中的convert

Oracle中的CONVERT函数是用于将一个字符串从一种字符集转换为另一种字符集的函数。它的语法如下：
CONVERT(string, destination_character_set, source_character_set)
登录后复制
其中，string表示要转换的字符串，destination_character_set表示目标字符集，source_character_set表示源字符集。
举个例子，如果要将一个UTF-8编码的字符串转换为GBK编码，可以使用以下语句：
CONVERT('你好，世界', 'GBK', 'UTF8')
登录后复制
这将返回一个GBK编码的字符串。需要注意的是，CONVERT函数只能用于单字节字符集和多字节字符集之间的转换，不能用于不同的Unicode字符集之间的转换。
