我无法为特定输出实现SQL Server存储过程

Question

我的存储过程如下： -

SET ANSI_NULLS ON
SET QUOTED_IDENTIFIER ON
GO

ALTER procedure [dbo].[sp_crystal_project_order_dtf_dttax]
     @id int
AS BEGIN
     SELECT  
         tbltax.taxname, ROUND(tbltax.taxamount,2) AS 'taxamount'
     FROM 
         (SELECT
              'Sub Total:' as 'taxname',
              sub_total1_factory as 'taxamount',
              -10 as 'OrderCol'
          FROM
              project_order_rewise
          WHERE
              project_order_rewise.[id] = @id

          UNION

          SELECT
              'Less Discount @ ' + cast(isnull([discount], 0) AS varchar(max)) + '%:' as 'taxname',
              (sub_total1_factory * isnull([discount], 0) / 100) AS 'taxamount',
              -9
          FROM
              [dbo].project_order_rewise
          WHERE
              [dbo].project_order_rewise.[id] = @id

          UNION

          SELECT
              'Packaging / Forwarding:' as 'taxname',
              transportation_charges_factory as 'taxamount',
              -8
          FROM
              project_order_rewise
          WHERE
              project_order_rewise.[id] = @id 

          UNION 

    select 'Sub Total:' as 'taxname'
            ,sub_total2_factory as 'taxamount'
            ,-7
    from [dbo].project_order_rewise
    where [dbo].project_order_rewise.[id]=@id

    union

    select 'Add '+[tax_master].[tax_name]+ ' @ '+cast([tax_value].[value]as varchar(max))+'%:' as 'taxname'
           ,project_order_tax.[amt_factory] as 'taxamount'
           ,-6
    from project_order_rewise inner join (tax_master inner join (project_order_tax inner join tax_value
        on project_order_tax.tax_value = tax_value.id)
        on tax_master.id=tax_value.tax_id)
        on project_order_rewise.id=project_order_tax.pro_order_rewise_id
    where project_order_rewise.id=@id 

    union

    select 'Sub Total:' as 'taxname'
            ,sub_total3_factory as 'taxamount'
            ,-5
    from project_order_rewise
    where project_order_rewise.[id]=@id

    union

    select 'Transportation Charges:' as 'taxname'
            ,newtransportchrg as 'taxamount'
            ,-4
    from project_order_rewise
    where project_order_rewise.[id]=@id

    union

    select 'Sub Total:' as 'taxname'
            ,subtotalwithtrans as 'taxamount'
            ,-3
    from project_order_rewise
    where project_order_rewise.[id]=@id

    union

    select 'Add '+[tax_master].[tax_name]+ ' @ '+cast([tax_value].[value]as varchar(max))+'%:' as 'taxname'
           ,project_order_tax1.[amount] as 'taxamount'
           ,-2
    from project_order_rewise inner join (tax_master inner join (project_order_tax1 inner join tax_value
        on project_order_tax1.tax_value = tax_value.id)
        on tax_master.id=tax_value.tax_id)
        on project_order_rewise.id=project_order_tax1.pro_order_rewise_id
    where project_order_rewise.id=@id 

    union

        select 'Grand Total:' as 'taxname'
            ,grandtotal1 as 'taxamount'
            ,-1
    from project_order_rewise
    where project_order_rewise.[id]=@id

    ) as tbltax

    order by OrderCol
end

exec sp_crystal_project_order_dtf_dttax 60

它返回此输出：

taxname                      taxamount
---------------------------------------
Sub Total:                     220
Less Discount @ 0.00%:           0
Packaging / Forwarding:          0
Sub Total:                     220
Add Excise Duty @ 12.36%:       27.19
Sub Total:                     247.19
Transportation Charges:          0
Sub Total:                     247.19
Grand Total:                   247.19

我已经以这种方式实现了我的程序，因为我想在一个中显示它 水晶报告。我不想要选择条款的结果，其中包括税收，折扣，包装/转发，税收，运输费用是0.我不想显示结果。当我使用where子句

时

where taxamount <> 0 or taxamount <> null

结果显示如下：

taxname                       taxamount
---------------------------------------
Sub Total:                    220
Add Excise Duty @ 12.36%:      27.19
Grand Total:                  247.19

当我在谷歌浏览器中执行页面时。在Crystal Reports中，结果显示如下：

taxname                      taxamount
--------------------------------------
Sub Total:                     220
Sub Total:                     220
Sub Total:                     220
Sub Total:                     220
Add Excise Duty @ 12.36%:       27.19
Sub Total:                     247.19
Sub Total:                     247.19
Sub Total:                     247.19
Grand Total:                   247.19

有人可以告诉我解决方法。
