Sql server date1的语法错误

我试过了，检查一下

SELECT FactOrders.TerritoryKey ,
       FactOrders.DistributorKey ,
       FactOrders.ItemKey ,
       SUM(FactOrders.UnitQty)as Quantity ,
       SUM(FactOrders.GrossValue) as Gross_Value 
FROM FactOrders 
WHERE FactOrders.TerritoryKey = @TerritoryKey and 
      FactOrders.DistributorKey = @DistributorKey and 
      FactOrders.DateKey >=CInt(Format(Paramters!@Date1.Value,"yyyyMMdd")) and 
      FactOrders.DateKey <= @Date2 AND 
      FactOrders.LineType = 'ORDER' 
GROUP BY FactOrders.TerritoryKey , FactOrders.DistributorKey ,FactOrders.ItemKey 
ORDER BY FactOrders.TerritoryKey , FactOrders.DistributorKey ,FactOrders.ItemKey

@Date1看起来像一个变量，但您是否在任何地方定义了它？为什么要访问属性？@Date1是我的ms sql报表编写器中的参数。它是日期类型参数。我想将其转换为intiger。@Dumindaaturaliyapathegama Date1=2017-01-31表示您需要转换为的基础int@Chanukya我想将2016年5月21日转换为20160521。因为在数据库中，日期用作整数。但在参数部分，我想将其用作日期类型。@Chanukya现在在将varchar值5/21/2016转换为数据类型int时给出转换失败，错误245
