从字符串转换日期和/或时间时，转换失败。


[解决办法]
PromTime是不是有非日期型的
select isdate(PromTime)
from dbo.Sales_Order
有没有0
[解决办法]
日期有格式不对的，转换失败了。
[解决办法]
@BeginDate 传进来的值是否不是日期格式
[解决办法]

探讨

晕了！地球人都知道是日期格式不对！请解决！

------解决方案--------------------

分别执行以下三段 union all 的代码，看看问题出在哪里
[解决办法]
你自己可以将那些时间全都Print @PromTime 出来，看看是哪步的时间转换出错了。
[解决办法]
加在你的select语句里啊，子查询里的select语句
[解决办法]
把你的语句单独放到SSMS查询窗口中，然后将两个传入参数直接改为2个日期值，运行下看看，如果有出错，SQL会提示第几行的。
[解决办法]
你先把 dbo.Sales_Order--订单销售表
的PromTime,--促销时间
时间格式规范
