mysql - 在字段中查找字符串的特定部分并将其替换为反斜杠

Question

例如，这是myTable:

| i | data    |
+---+---------+
| 1 | d\one   |
| 2 | d\two   |
| 3 | d\three |

但我想将其更改为:

| i | data  |
+---+-------+
| 1 | one   |
| 2 | two   |
| 3 | three |

我知道如何在字段中查找带有反斜杠的字符串的特定部分:

SELECT * FROM myTable WHERE data LIKE 'd%\%'

我知道如何查找和替换字段值，只有这个查询不起作用:

UPDATE myTable SET data=REPLACE(data,'d\','') WHERE data LIKE 'd%\%'

Answer 1

您需要转义反斜杠

UPDATE myTable 
SET data = REPLACE(data,'d\\','') 
WHERE data INSTR('d\\') = 1
