Question

我在SQL Server 2012数据库中有不同的表，具有以下结构：

userstbl拥有用户full_name和ID - ＆gt;这有牙医的信息。
bookingtbl有Id，patient_ID（与另一个表相关，有患者的信息文件），booking_date，InvoiceID（与另一张表Invoice相关）。
servicetbl：ID，service_id（与另一个具有服务费用的表相关），booking_ID。
invoicetbl：ID，TotalCost。

我希望从我的程序中得到的是返回：

user_ID为DrD，Full_name为DrName，预订次数，服务次数，发票总额之和。

基于给定日期。

我试过以下但是smthn仍然缺失：

create Proc SelectDrWork(@date Date)
as
begin
    select 
        userstbl.[user_id],userstbl.full_name,
        count(bookingtbl.bookingID), 
        count(servicetbl.serviceID),
        sum(invoice.Total)
    from 
        userstbl, bookingtbl, Servicetbl, invoice
    where 
        userstbl.IsActivated = 'True' 
        and userstbl.description = 'Dr'
        and bookingtbl.dr_id = [user_id] 
        and cast(bookingtbl.[date] as date) = cast(@date as date)
        and servicetbl.booking_id = book_number 
        and invoice.inv_id = bookingtbl.invoiceID 
    group by 
        [user_id], book_number, diaganosis_serv_id
end

Answer 1

我想出了答案。非常简单：

ALTER Proc SelectDrWork(@date Date)
as
begin
select userstbl.[user_id],userstbl.full_name,count(distinct book_number) as BookingCount,count(service_id)as ServiceCount,sum(invoice.Total) as Total
from userstbl, bookingtbl, diaganosistbl, invoice
where userstbl.IsActivated='True' and userstbl.description='Dr'
and bookingtbl.dr_id=[user_id] 
and cast(bookingtbl.[date] as date)= cast(@date as date)
and diaganosistbl.booking_id=book_number 
and invoice.inv_id=bookingtbl.invoiceID 
group by [user_id],full_name
end

SQL Server返回多个值在单个查询中使用来自不同表的COUNT
