[英]SQL query - how to get counts in table
我有一个表X,其中有一个名为version的列,其中包含4-5个值,例如1,2,3,4,5
如果列值为1或3,那么我很好,否则它是错误的
什么是查询,以便我想要这样的输出
总数#| 总好,即值为(1,3)| 总失败,即价值不在(1,3)
有人可以帮我查询一下
你可以试试这个:
select count(*) as TotalValues
, (select count(*) from test where id in(1, 3)) as TotalGood
, (select count(*) from test where id not in (1, 3)) as TotalFailed
from test
根据您的评论,如果您需要百分比,您将使用此:
SELECT TotalValues
, TotalGood
, TotalFailed
, Cast(TotalGood as decimal(10, 2))/Cast(TotalValues as decimal(10, 2)) as PercentGood
FROM
(
select count(*) as TotalValues
, (select count(*) from test where id in(1, 3)) as TotalGood
, (select count(*) from test where id not in (1, 3)) as TotalFailed
from test
) x
