这是我的后端codeI是无法转换它，每次它给了我“操作数类型冲突：日期与诠释不兼容”这一错误...请帮助 – Mac

我newto堆栈溢出，请原谅我 – Mac

你可以发布你在这个查询中使用的表的表结构吗？ –

我认为这些行是错误的来源：

and ED.StartDate = '+CAST('2016-01-01' as nvarchar)+' 
and ED.EndDate ='+CAST('2016-01-04' as nvarchar)+'

在最后@x值，其作为SQL执行时，它会变得

and ED.StartDate = 2016-01-01 
and ED.EndDate = 2016-01-04

2016-01-01看起来像一个日期给我们，人类，但SQL Server看到一个（计算的）整数：2014（2016减1减1）。用引号括起日期（省略CAST，因为我不明白为什么要将日期字符串转换为nvarchar）。

and ED.StartDate = ''2016-01-01''' +' 
and ED.EndDate =''2016-01-04''' +'
