sql查询季度有关问题
sql查询季度问题?
有一张SQL数据表EM,有销售合同号(accid),员工编号(emid),销售日期(ShippedDate)和销售金额(account)—4个字段,编写计算出2010年各个季度中,公司销售总份数与总销售金额?
select year(ShippedDate) as 年份,
sum
(
case when
month(ShippedDate) in (1,2,3))
then count(accid) as 销售总份数,sum(account) as 销售总金额
else 0
) as 第一季度
from EM where ShippedDate like'2010?'
group by year(ShippedDate)
order by year(ShippedDate)
请各位帮忙看看,我这么写有问题吗?

- SQL code
select year(ShippedDate) as 年份, sum ( case when month(ShippedDate) in (1,2,3)) then count(accid) end as 销售总份数,sum(account) as 销售总金额 --这里的end忘记了哦 else 0 ) as 第一季度 from EM where ShippedDate like'2010%' --还有这里的? 要用% group by year(ShippedDate) order by year(ShippedDate)
