Question

我想从

删除（Apple Banana）

String =＆＃39;我买了Apple，Banana，Orange和Mango＆＃39;

NewString =＆＃39;我买了，Orange和Mango＆＃39;

Answer 1

这个怎么样？

select replace(
          replace('I bought Apple , Banana , Orange and Mango', 'Apple'),
      'Banana') 
from dual;

或

declare
  my_string varchar2(50) := 'I bought Apple , Banana , Orange and Mango';
begin
  my_string := replace(replace(my_string, 'Apple'), 'Banana');
end;

Answer 2

使用REGEXP_REPLACE避免将多个替换函数链接在一起。

SELECT REGEXP_REPLACE(my_string, 'Apple|Banana', '') FROM my_table

Answer 3

select regexp_replace(source_string, '(^|\W)(Apple|Banana)(\W|$)', '\1\3', 1, 0, 'i') as new_string
  from (select  'I bought Apple , Banana , Orange and Mango' as source_string 
     from dual);


NEW_STRING  
I bought  ,  , Orange and Mango

此代码取代整个单词“Apple”或“Banana”不区分大小写。

Answer 4

我会尝试这样的事情

选择替换（替换（'我买了苹果，香蕉，橙和芒果'，'苹果'），'香蕉'）来自双重;

如何从String中删除特定单词？
