推荐答案

结果有什么问题?它将ä 替换为ae.现在对所有其他字符重复.... 因为 replace 只会用另一个替换 1 个序列，所以你会得到很多嵌套的替换.

What's wrong with the result? It replaces ä with ae. Now repeat for all other characters.... Since replace will only replace 1 sequence with another you will get a lot of nested replaces.

select replace(replace('a b c d e ä f g ö','ä','ae'),'ö','oe') from dual
