DATEDIFF( XXXX-XX-XX,XXXX-XX-XX)

1：

SELECT
    SUM(
        ABS( datediff( NOW() ,sal_end_date ) ) = 205
    ) AS aa
FROM
    k_insurance_bill

datediff ( 当前时间，结束时间 )

2：

select sum(abs(datediff(now(),sal_end_date)) in(207,205,30)) as aa from k_insurance_bill

一句代码算出三个变量的和

3：

select 
	90,
	sum(ABS( datediff( NOW() ,sal_end_date ) ) = 205 ) as aa
from k_insurance_bill
union
select 
	60,
	sum(ABS( datediff( NOW() ,sal_end_date ) ) = 207 ) as aa
from k_insurance_bill
union
select 
	30,
	sum(ABS( datediff( NOW() ,sal_end_date ) ) = 30 ) as aa
from k_insurance_bill

可以查到一个二列三行的表

4：

SELECT 
	b.CREATE_BY,
	SUM(DATEDIFF(sal_end_date,NOW()   ) = 205 ) AS  '90',
	SUM(DATEDIFF(sal_end_date,NOW()   ) = 207 ) AS  '60', 
	SUM(DATEDIFF(sal_end_date,NOW()   ) = 30 ) AS  '30' 
from k_insurance_bill a
left join
k_ins_requirement b
on a.r_id=b.id
group by b.CREATE_BY

根据id分组查询
