我只想要一个选择查询,它可以选择1986年以后出生的所有用户uid。
我尝试过此查询,但只选择匹配的号码LIKE
搜索。
SELECT uid FROM {profile_values} WHERE value LIKE '%1986%'
这是SQL查询
CREATE TABLE IF NOT EXISTS `profile_values` (
`fid` int(10) unsigned NOT NULL DEFAULT '0',
`uid` int(10) unsigned NOT NULL DEFAULT '0',
`value` text,
PRIMARY KEY (`uid`,`fid`),
KEY `fid` (`fid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO `profile_values` (`fid`, `uid`, `value`) VALUES
(5, 1, 'a:3:{s:3:"day";s:2:"27";s:5:"month";s:1:"6";s:4:"year";s:4:"1986";}'),
(5, 3, 'a:3:{s:3:"day";s:2:"15";s:5:"month";s:1:"9";s:4:"year";s:4:"1910";}'),
(5, 4, 'a:3:{s:3:"day";s:2:"26";s:5:"month";s:1:"6";s:4:"year";s:4:"1986";}'),
(5, 5, 'a:3:{s:5:"month";s:1:"4";s:3:"day";s:2:"26";s:4:"year";s:4:"2014";}'),
(5, 6, 'a:3:{s:3:"day";s:2:"26";s:5:"month";s:1:"4";s:4:"year";s:4:"2014";}'),
(5, 7, 'a:3:{s:5:"month";s:1:"4";s:3:"day";s:2:"26";s:4:"year";s:4:"2014";}'),
(5, 8, 'a:3:{s:3:"day";s:2:"26";s:5:"month";s:1:"4";s:4:"year";s:4:"1987";}'),
(5, 17, 'N;'),
(5, 18, 'N;'),
答案 0 :(得分:0)
您可以尝试使用REGEXP。 REGEXP匹配条件类似于LIKE,但LIKE仅使用通配符执行简单模式匹配"%"和" _",REGEXP执行复杂的正则表达式模式匹配,允许它匹配比LIKE更大范围的字符串模式。
SELECT uid FROM {profile_values}
WHERE value REGEXP '[1][9][8][6-9]|[1][9][9][0-9]|[2-9][0-9][0-9][0-9]';
在这里,我们确保我们的表达式只考虑4位数字,而且数字应该大于1986
so [1][9][8][6-9] -->> makes sure number is between 1986 to 1989
next [1][9][9][0-9] -->> makes sure number is between 1990 to 1999
last [2-9][0-9][0-9][0-9] -->> makes sure number is between 2000 to 9999
