C# 如何从字符串转换日期时间

试试这个

select dbo.CLOI_ClientOrderItems.cl_id, sum(dbo.IN_Invoices.in_total) as Total
from CLOI_ClientOrderItems
inner join IN_Invoices on CLOI_ClientOrderItems.MasterOrderId=IN_Invoices.MasterOrderId
where dbo.IN_Invoices.in_date_issued='2014-01-21 12:30:51.190'
group by cl_id;

试试这个

select dbo.CLOI_ClientOrderItems.cl_id, sum(dbo.IN_Invoices.in_total) as Total
from CLOI_ClientOrderItems
inner join IN_Invoices on CLOI_ClientOrderItems.MasterOrderId=IN_Invoices.MasterOrderId
where dbo.IN_Invoices.in_date_issued='2014-01-21 12:30:51.190'
group by cl_id;

正确地解释你想要什么？正确地解释你想要什么？发票中的dbo.IN_date_issued=CAST（'2014-01-21 12:30:51.190'作为日期时间）如果我像marchwhere dbo.IN_Invoices.IN_date_issued=CAST（'2014-01-21 12:30:51.190'作为日期时间）那样过了一个月，日期的分期如果我过了像三月这样的月份，日期的设置

select 
    dbo.CLOI_ClientOrderItems.cl_id, 
    sum(dbo.IN_Invoices.in_total) as Total
from 
    CLOI_ClientOrderItems
    inner join IN_Invoices 
on 
    CLOI_ClientOrderItems.MasterOrderId=IN_Invoices.MasterOrderId
where 
    dbo.IN_Invoices.in_date_issued=CONVERT(datetime, '2014-01-21 12:30:51.190', 120)
