sql 替换一列中的两个字符串

Question

我想替换单个字符串中的两个字符。

替换

Name 
I am not aware of any or potential that hasn’t yet been reported

和

Name 
I am not aware of any/potential that hasn't yet been reported

我用过这个查询：

replace(Replace(Name, ' or ', '/'), '’', ''')

但是我得到一个错误

ORA-01756: quoted string not properly terminated

Answer 1

我真的不明白你想用你的双重替换做什么。你可以只使用一个：

SELECT REPLACE(name,' or ','/') newstring FROM yourstrings;

如果你真的需要双重替换，你也可以这样做：

SELECT REPLACE(REPLACE(name,' or ','/'),'’','''') newstring FROM yourstrings;

更有趣的是如何插入包含撇号、引号等的字符串。您可以使用 q 运算符来完成，例如：

INSERT INTO yourstrings VALUES 
(q'[I am not aware of any or potential that hasn’t yet been reported ]');

请看这个工作示例：db<>fiddle

Answer 2

select replace(replace
('I am not aware of any or potential that hasn’t yet been reported',' or ','/'),
'’','''') 
from dual;
