非常新的SQL并尝试设置用户表,我有一个财务援助复选框,输出BIT 0或1,理想情况下我想要做的是将此值转换为YES或NO取决于价值。现在我不完全确定如何做到这一点,我已经尝试添加
SELECT CASE `financial_aid`
WHEN 1 THEN 'Yes'
WHEN 0 THEN 'No'
END As `financial_aid`
FROM `users`;
目前这并没有解决我的问题,有人可以建议我如何解决这个问题吗?
SQL
CREATE TABLE IF NOT EXISTS `users` (
`User_id` mediumint(8) unsigned NOT NULL AUTO_INCREMENT,
`player_name` varchar(40) NOT NULL,
`gender` varchar(10) NOT NULL,
`dob` date NOT NULL,
`parent_name` varchar(40) NOT NULL,
`parent_email` varchar(40) NOT NULL,
`parent_phone` varchar(40) NOT NULL,
`experience` varchar(40) NOT NULL,
`financial_aid` bit NOT NULL,
`registration_date` datetime NOT NULL,
PRIMARY KEY (`User_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=10;
SELECT CASE `financial_aid`
WHEN 1 THEN 'Yes'
WHEN 0 THEN 'No'
END As `financial_aid`
FROM `users`;
答案 0 :(得分:2)
尝试IF(true, x, y)
功能...
SELECT IF(`financial_aid`, 'Yes', 'No') As `financial_aid` FROM `users`;
或者只是
SELECT case `financial_aid`
WHEN TRUE 'Yes'
ELSE 'No' END
As `financial_aid`
FROM `users`;
