Question

我有一个存储过程，我想返回三列，它们只包含根据今天的日期，本周和当前月份的记录计数

SELECT count(*) as TotalCount 
FROM CalendarItem t 
LEFT JOIN company c ON t.companyID = c.companyID AND c.enabled = 1 
INNER JOIN CalendarItemType tt ON tt.CalendarItemtypeID = t.CalendarItemTypeID 
LEFT JOIN request r ON r.requestID=t.workrequestID 

where t.deleted = 0  + @where

当前我通过传递不同的arg

来执行这个Sp三个时间今天一周和一个月

@where =AND (t.startDate BETWEEN '2013-7-17' AND '2013-7-18')

和周

@where = AND (t.startDate BETWEEN '2013-7-14 00:00:00' AND '2013-7-20')

和月份一样

我希望我的SP根据今天的日期，星期和MOnth

返回三个计数

所以任何想法我应该怎么做

由于

Answer 1

将三个输出参数传递给存储过程，并将其值设置为sp，然后很容易将其取回

Answer 2

请尝试：

SELECT 
    sum(case when t.startDate BETWEEN '2013-7-17' AND '2013-7-18' then 1 else 0 end) as DayCount,
    sum(case when t.startDate BETWEEN '2013-7-14' AND '2013-7-20' then 1 else 0 end) as WeekCount,
    //month condition here
FROM CalendarItem t 
LEFT JOIN company c ON t.companyID = c.companyID AND c.enabled = 1 
INNER JOIN CalendarItemType tt ON tt.CalendarItemtypeID = t.CalendarItemTypeID 
LEFT JOIN request r ON r.requestID=t.workrequestID 

where t.deleted = 0

从存储过程中返回三列
