如何使用多个参数成功进行子查询

Question

我有两张桌子PA_Ledger 和PA_Trans。我刚刚写了一个存储过程，它可以过滤日期、内部连接、按PA_Ledger.Name 分组并按该名称排序。

我有一个存储过程，可以通过加入、分组和日期过滤器查找记录，如下所示：

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

    @PageSize int,
    @PageIndex int,
    @startdt1 nvarchar(50),  
    @startdt2 nvarchar(50),
    @Sort nvarchar(50),
    @Search nvarchar(max)
AS
BEGIN
    SET NOCOUNT ON;

    DECLARE @qry nvarchar(max)
    DECLARE @TotalRecords nvarchar(max)

    SET @TotalRecords=' ( select count(*) from PA_Ledger pl join PA_Trans pt on (pl.LedgerId = pt.Ledgeridcr or pl.LedgerId = pt.Ledgeriddr ) 
                         where isnull(Isdeleted,0) = 0 and pl.Name like ''%'+@Search+'%'' 
                          and (pt.TransOn >= '''+convert(nvarchar,CONVERT(DATETIME,@startdt1,110))+''' or convert(date,'''+convert(nvarchar,CONVERT(DATETIME,@startdt1,110))+''') = convert(date,''01/01/1900'') )
                         and (pt.TransOn <='''+convert(nvarchar,CONVERT(DATETIME,@startdt2,110))+''' or convert(date,'''+convert(nvarchar,CONVERT(DATETIME,@startdt2,110))+''') = convert(date,''01/01/1900'') )
                         group by pl.Name)'
    

    
    set @qry = ' select  *, '+@TotalRecords+' As TotalRecords,                  
                        (select row_number() over(order by pl.name) as RowNo,pl.Name,sum(pt.Amount) as Amount
                         from PA_Ledger pl
                         join PA_Trans pt on (pl.LedgerId = pt.Ledgeridcr or pl.LedgerId = pt.Ledgeriddr)
                         and pl.Name like ''%'+@Search+'%'' and
                         isnull(Isdeleted,0) = 0 
                         and (pt.TransOn >= '''+convert(nvarchar,CONVERT(DATETIME,@startdt1,110))+''' or convert(date,'''+convert(nvarchar,CONVERT(DATETIME,@startdt1,110))+''') = convert(date,''01/01/1900'') )
                         and (pt.TransOn <='''+convert(nvarchar,CONVERT(DATETIME,@startdt2,110))+''' or convert(date,'''+convert(nvarchar,CONVERT(DATETIME,@startdt2,110))+''') = convert(date,''01/01/1900'') )
                         group by Name 
                        ) i where RowNo between  '+Convert(nvarchar(10),( (@pageIndex-1) * @pageSize  ) + 1 )+ ' and '  + Convert(varchar(10),( (@pageIndex-1) * @pageSize  ) + @pageSize) + ' '+ @Sort

    
    print(@qry)             
    exec(@qry+@TotalRecords)
    
END

当我执行时会产生如下错误：

( select count(*) from PA_Ledger pl join PA_Trans pt on (pl.LedgerId = pt.Ledgeridcr or pl.LedgerId = pt.Ledgeriddr ) 
                         where isnull(Isdeleted,0) = 0 and pl.Name like '%%' 
                          and (pt.TransOn >= 'Oct 28 2021 12:00AM' or convert(date,'Oct 28 2021 12:00AM') = convert(date,'01/01/1900') )
                         and (pt.TransOn <='Oct 30 2021 12:00AM' or convert(date,'Oct 30 2021 12:00AM') = convert(date,'01/01/1900') )
                         group by pl.Name)

                         group by pl.Name) As TotalRecords,
                        
                        (select row_number() over(order by pl.name) as RowNo,pl.Name,sum(pt.Amount) as Amount

消息 207，第 16 层，状态 1，第 27 行
列名“RowNo”无效。

消息 207，第 16 层，状态 1，第 27 行
列名“RowNo”无效。

消息 263，第 16 级，状态 1，第 13 行
必须指定要从中选择的表。

消息 116，第 16 级，状态 1，第 27 行
当子查询不使用 EXISTS 引入时，选择列表中只能指定一个表达式。

消息 207，第 16 层，状态 1，第 27 行
列名“名称”无效。

此存储过程的更好解决方案是什么？请帮助我摆脱这种情况。

Answer 1

好吧，你还没有给我们创建/插入查询，所以我们必须盲目。尝试更改set @qry 的第一行：

set @qry = ' select  *, '+@TotalRecords+' As TotalRecords,  

到这里：

set @qry = ' select  *, '+@TotalRecords+' As TotalRecords, i.* from 

这将导致您的括号 (...) i 成为派生表而不是单个值，并且我们选择它的所有元素 , i.*

另外，将@totalrecords 更改为具有备用别名的此版本：

set @TotalRecords=' ( select count(*) from PA_Ledger pl2 join PA_Trans pt2 on (pl2.LedgerId = pt2.Ledgeridcr or pl2.LedgerId = pt2.Ledgeriddr ) 
                         where isnull(Isdeleted,0) = 0 and pl2.Name like ''%'+@Search+'%'' 
                          and (pt2.TransOn >= '''+convert(nvarchar,CONVERT(DATETIME,@startdt1,110))+''' or convert(date,'''+convert(nvarchar,CONVERT(DATETIME,@startdt1,110))+''') = convert(date,''01/01/1900'') )
                         and (pt2.TransOn <='''+convert(nvarchar,CONVERT(DATETIME,@startdt2,110))+''' or convert(date,'''+convert(nvarchar,CONVERT(DATETIME,@startdt2,110))+''') = convert(date,''01/01/1900'') )
                         group by pl2.Name)'
