对SELECT中的单个字段进行双重REPLACE

Question

如何在同一个字段上运行两次替换的选择？

SELECT `id`, `name`, `address`, REPLACE( `info`, '|', '-' ) AS `info` 
INTO OUTFILE '/tmp/" . $SESSION . "NET_SCAN.csv' 
FIELDS TERMINATED BY '|' 
ENCLOSED BY '' 
LINES TERMINATED BY '\n' 
FROM `net_scan`;

我想在同一个字段上运行辅助REPLACE。

Answer 1

只需在其中使用REPLACE。

REPLACE(REPLACE(field, 'bad', 'good'), 'better', 'worse')

Answer 2

replace(REPLACE( `info`, '|', '-' ), 'x', 'y'))
