Mysql 错误 #1054 - 更新时“where 子句”中的未知列“Y”

Question

I have a table 'client' where a column 'wipes' is currently filled with Y or N. I want to change Y and N to 1 and 0. I am trying this query and getting the error "Unknown column 'Y' in 'where clause'" I have tried every combination of with backticks, without backticks, single quotes, etc... Why does it think that 'Y" is a column?

UPDATE client
SET wipes = `1`
WHERE wipes = `Y`;

Thank you!

Answer 1

Maybe you should use a single quote like

UPDATE client
SET wipes = 1
WHERE wipes = 'Y';

UPDATE `client` SET `wipes` = CASE
WHEN wipes= 'Y' THEN 1
WHEN wipes = 'N' THEN 0
END

Answer 2

I Got it, slightly stupid. It should be

WHERE wipes LIKE 'Y'; 

that worked. I don't know if it would be the same in every sql version. But I'm using phpMyadmin.
