Mybatis中使用CASE WHEN表达式，可以实现根据条件进行复杂逻辑判断和数据转换。CASE WHEN有简单形式和搜索形式两种。简单形式为：CASE sex WHEN '1' THEN '男' WHEN '2' THEN '女' ELSE '其他' END 搜索形式为：CASE WHEN sex = '1' THEN '男' WHEN sex = '2' THEN '女' ELSE '其他' E...
WHEN ‘1’ THEN ‘男’ WHEN ‘2’ THEN ‘女’ ELSE ‘其他’ END –Case搜索函数 CASE WHEN sex = ‘1’ THEN ‘男’ WHEN sex = ‘2’ THEN ‘女’ ELSE ‘其他’ END 两 种方式,可以实现相同的功能。简单Case函数的写法相对比较简洁,但是和Case搜索函数相比,功能方面会有些限制,比如写判断式。...
count(case when ob.apply_status > 1 and ob.apply_status < 6 then ob.apply_status end) as sumInProgressCount, count(case when ob.apply_status = 7 then ob.apply_status end) as sumFailLoanCount, count(case when ob.release_status = 1 then ob.release_status end) as sumReleaseCount, su...
CASE WHEN ID = 1 THEN 'PASSWORD1' WHEN ID = 2 THEN 'PASSWORD2' WHEN ID = 3 THEN 'PASSWORD3' END image.gif 以上形态中case后未跟任何内容,而是采取了搜索的方式进行更新,也就是说在整张表中搜索ID=1,ID=2,ID=3的数据进行更新。
