Sql 行数超过文本列排序

我在SQL Server中使用行号进行动态排序时遇到问题。我让它工作，但它在非数字字段上抛出错误。我需要做什么改变才能让Alpha正常工作

ID  Description
5   Test    
6   Desert  
3   A evil  

我有一个Sql产品

CREATE PROCEDURE [CRUDS].[MyTable_Search]
    -- Add the parameters for the stored procedure here
    -- Full Parameter List  
    @ID int = NULL,     
    @Description nvarchar(256) = NULL,  
    @StartIndex int = 0,
    @Count int = null,
    @Order varchar(128) = 'ID asc'
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    -- Insert statements for procedure here
Select * from
    (
        Select ROW_NUMBER() OVER 
            (Order By
                case 
                    when @Order = 'ID asc' then [TableName].ID  
                    when @Order = 'Description asc' then [TableName].Description    
                end asc,
                case
                    when @Order = 'ID desc' then [TableName].ID 
                    when @Order = 'Description desc' then [TableName].Description   
                end desc
            ) as row,
            [TableName].* from [TableName]
        where 
            (@ID IS NULL OR [TableName].ID = @ID)  AND
            (@Description IS NULL OR [TableName].Description = @Description)
) as a
where 
    row > @StartIndex  
    and (@Count is null or row <= @StartIndex + @Count)
 order by
    case 
        when @Order = 'ID asc' then a.ID    
        when @Order = 'Description asc' then a.Description  
    end asc,
    case
        when @Order = 'ID desc' then a.ID   
        when @Order = 'Description desc' then a.Description 
    end desc


END

这对我来说很好：

declare @TableName table (id int,Description varchar(50))
insert @TableName values (1,'aaa') 
insert @TableName values (2,'bbb') 
insert @TableName values (3,'ccc') 
insert @TableName values (4,'ddd') 
insert @TableName values (5,'eee') 
insert @TableName values (6,'fff') 
insert @TableName values (7,'ggg') 
insert @TableName values (8,'hhh') 
DECLARE @Order         varchar(10)
       ,@ID            int
       ,@Description   varchar(50)
       ,@StartIndex    int
       ,@Count         int

SELECT @Order='Description desc'
      ,@StartIndex=2
      ,@Count=3

--query unchanged, except alias to "t" and table name to "@TableName"
Select * from
    (
        Select ROW_NUMBER() OVER 
            (Order By
                case 
                    when @Order = 'ID asc' then t.ID  
                    when @Order = 'Description asc' then t.Description    
                end asc,
                case
                    when @Order = 'ID desc' then t.ID 
                    when @Order = 'Description desc' then t.Description   
                end desc
            ) as row,
            t.* from @TableName  t
        where 
            (@ID IS NULL OR t.ID = @ID)  AND
            (@Description IS NULL OR t.Description = @Description)
) as a
where 
    row > @StartIndex  
    and (@Count is null or row <= @StartIndex + @Count)
 order by
    case 
        when @Order = 'ID asc' then a.ID    
        when @Order = 'Description asc' then a.Description  
    end asc,
    case
        when @Order = 'ID desc' then a.ID   
        when @Order = 'Description desc' then a.Description 
    end desc

根据OP的评论进行编辑，请尝试以下操作：

declare @TableName table (id int,Description varchar(50))
insert @TableName values (1,'1') 
insert @TableName values (2,'bbb') 
insert @TableName values (3,'ccc') 
insert @TableName values (4,'ddd') 
insert @TableName values (5,'eee') 
insert @TableName values (6,'fff') 
insert @TableName values (7,'ggg') 
insert @TableName values (8,'hhh') 
DECLARE @Order         varchar(50)
       ,@ID            int
       ,@Description   varchar(50)
       ,@StartIndex    int
       ,@Count         int

SELECT @Order='Description desc'
      ,@StartIndex=2
      ,@Count=3

Select * from
    (
        Select ROW_NUMBER() OVER 
            (Order By
                case 
                    when @Order = 'ID asc' then RIGHT(REPLICATE('0',10)+CONVERT(varchar(10),t.ID),10)
                    when @Order = 'Description asc' then t.Description    
                end asc,
                case
                    when @Order = 'ID desc' then RIGHT(REPLICATE('0',10)+CONVERT(varchar(10),t.ID),10)
                    when @Order = 'Description desc' then t.Description   
                end desc
            ) as row,
            t.* from @TableName  t
        where

旁注：将@Count is null条件添加到谓词将大大降低查询速度。您应该将该行更改为或行您是否解决了此问题？我认为如果您的选择已经有一个，您不需要额外的顺序。仍在寻找比将所有内容转换为字符并在左侧填充零更优雅的内容。将@ORDER更改为varchar50而不是10，10是截断排序顺序，因此排序部分被跳过。因此，基本上，我必须将所有列转换为单个数据类型varchar进行排序？我在表中还有其他列，只是想确定一下。我总是将其转换为字符串，但我通常在排序时合并列，以区分主列何时可能有重复的列。例如，如果按日期排序，则不希望包含其他列，因为可能存在具有相同日期的行。当您转换为字符串时，请考虑它们的排序方式：数字需要前导零，否则您将得到1,10,11,2,22。。。使用样式121 YYYY-MM-DD hh:mi:ss.mmm格式化日期时间，在列之间放置管道|或其他内容，填充空值等。
