select t1.InvoiceNumber ,t1.LocalAmount  , t2.LineAmount as discount , t1.CreateDate
from CashOrderTrn t1 
left join DistrubutedDiscountDetails t2 
    on t1.InvoiceNumber =  t2.InvoiceNumber  
    and t1.CreateDate between '20160531' and  '20160701' 
    and t1.InvoiceType ='31'

我希望将日期 (22/03/2016 23:59:59) 格式化为以毫秒为单位的字符串。

dr.GetDateTime(1).ToString("yyyy-MM-dd hh:mm:ss")

1. .ToString("yyyy-MM-dd")
2. .ToString("hh':'mm':'ss")
