Question

您好我想在同一份报告中提供年度和两年前的信息的销售报告。我有这个查询作为选择2007年的例子，但我需要做年复一年，然后是2012,2011,2010。在同一份报告中。任何的想法？感谢

我有选择，字段名称，从表格， DocDate＆gt; ='2007-01-01'和DocDate＆lt; ='2007-12-31'

Answer 1

要做年份，只需将'WHERE DocDate＆gt; = 2013-01-01'

每年制作一个WHERE条件'WHERE DocDate＆gt; = 2012-01-01和DocDate＆lt; = 2012-12-12'

Answer 2

CREATE PROCEDURE GetSalesReport 
    @Year AS INT
AS
BEGIN
    DECLARE @DateFrom AS DATETIME
    DECLARE @DateTo AS DATETIME

    SET @DateFrom = CONVERT(DATETIME,CONVERT(VARCHAR(4),@Year)+'0101')
    SET @DateTo = GETDATE()

    select field names 
    from tables
    where DocDate > = @DateFrom and DocDate <=@DateTo

    SET @DateFrom = CONVERT(DATETIME,CONVERT(VARCHAR(4),@Year-1)+'0101')
    SET @DateTo = CONVERT(DATETIME,CONVERT(VARCHAR(4),@Year-1)+'1231')

    select field names 
    from tables
    where DocDate > = @DateFrom and DocDate <=@DateTo


    SET @DateFrom = CONVERT(DATETIME,CONVERT(VARCHAR(4),@Year-2)+'0101')
    SET @DateTo = CONVERT(DATETIME,CONVERT(VARCHAR(4),@Year-2)+'1231')

    select field names 
    from tables
    where DocDate > = @DateFrom and DocDate <=@DateTo
END

Answer 3

如果您想要当前年初至今PLUS的所有数据超过2 - 3年（标题显示2，帖子显示3）

select
      YEAR(DocDate) as EachYear,
      field names
   from 
      tables
   where 
      DocDate > = '2007-01-01'
   order by
      EachYear DESC

现在，如果您正在尝试某些聚合，例如年度销售额，总计等，您可以为＆＃34; EveryYear＆＃34;等应用GROUP BY。计算列

select
      YEAR(DocDate) as EachYear,
      sum( someTable.orderAmt ) as TotalOrdered,
      count(*) as NumberOrders,
      avg( someTable.OrderAmt ) as AvgOrder
   from 
      tables
   where 
      DocDate > = '2007-01-01'
   GROUP BY
      Year(DocDate)
   order by
      Year(DocDate) DESC
