将日期时间插入日期时间字段TSQL

Question

我想从C＃程序中调用SQL Server 2012 Express中的存储过程以将DateTime数据类型插入列（也是日期时间）。

出于某种原因，我不断收到有关“通过字符串转换日期和/或时间时会话失败”的错误。

我已经检查了我的SQL服务器的文化设置，它设置为us_english，但日期时间格式是ISO标准。

以下是存储过程中的代码。这些值完全是C＃应用程序传递的。

USE testdb; 
DECLARE @Name NVARCHAR(50) = 'Somename', 
    @Location NVARCHAR(50) = 'somelocation', 
    @Date DateTime = '2013-10-11 11:00:05.000' 

BEGIN 

SET NOCOUNT ON; 

SELECT @Name, @Location, @Date 

if exists (select name from ComputerHistory where name = @Name) 
    begin 
     DECLARE @Query1 NVARCHAR(MAX) 
     if @Location <> 'disconnected' 
      begin 
       set @Query1 = ' 
        update ComputerHistory 
        set ' + @Location + ' = 1 + ISNULL((select MAX(' + @Location + ') from ComputerHistory where name = ''' + @Name + '''),0), 
        lastdateonline = ''' + @Date + ''' 
        where name = ''' + @Name + ''' 
        ' 

       --EXEC sp_executesql @Query1 
      end 
     else 
      begin 
       set @Query1 = ' 
        update ComputerHistory 
        set ' + @Location + ' = 1 + ISNULL((select MAX(' + @Location + ') from ComputerHistory where name = ''' + @Name + '''),0) 
        where name = ''' + @Name + ''' 
        ' 
       EXEC sp_executesql @Query1 
      end 
    end 
else 
    begin 
     DECLARE @Query2 NVARCHAR(150) 
     set @Query2 = 'insert into ComputerHistory(name, ' + @Location + ') VALUES(''' + @Name + ''', ''1'')' 
     EXEC sp_executesql @Query2 
    end 
END

尝试投（@date如为nvarchar（50））

   set @Query1 = ' 
       update ComputerHistory 
       set ' + @Location + ' = 1 + ISNULL((select MAX(' + @Location + ') from ComputerHistory where name = ''' + @Name + '''),0), 
       lastdateonline = ''' + cast(@Date as nvarchar(50)) + ''' 
       where name = ''' + @Name + ''' 
       '
