MySql 更新查询中的反斜杠不起作用

Question

Running the following query in MySql workbench as \ is an escape character.

UPDATE midshared.SETUP
SET DATAVALUE = 'C:\Documents and Settings\ADMINISTRATOR\Desktop\'
WHERE CODE = 'SAGEPATH'

manually changing to this does work.

UPDATE midshared.SETUP
SET DATAVALUE = 'C:\\Documents and Settings\\ADMINISTRATOR\\Desktop\\'
WHERE CODE = 'SAGEPATH'

However trying these methods that I've found on Stack Overflow don't work either -

UPDATE midshared.SETUP
SET DATAVALUE = REPLACE('C:\Settings\ADMINISTRATOR\Desktop\','\','\\')
WHERE CODE = 'SAGEPATH'

or

UPDATE midshared.SETUP
SET DATAVALUE = QUOTE('C:\Documents and Settings\ADMINISTRATOR\Desktop\')
WHERE CODE = 'SAGEPATH'

Can anyone point me in the right direction to fix it please? Thanks A

I tried the queries listed above

Answer 1

You can use double quotes safely and escape slashes as follows:

UPDATE midshared.SETUP
SET DATAVALUE = "'C:\\Documents and Settings\\ADMINISTRATOR\\Desktop\\'"
WHERE CODE_ = 'SAGEPATH'
