Sql server 列名“Results”无效

抛出错误：

列名“Results”无效

如何解决它？

如果我正确理解您的问题，您应该先执行动态sql，然后再从临时表中选择

alter PROCEDURE sp_Get_CustInfoSerach2    
      (@PageIndex INT = 1
      ,@PageSize INT = 10
      ,@RecordCount INT OUTPUT
      ,@ColumnName VARCHAR(50)=null
      ,@Value VARCHAR(50)=null
      ,@ddlValue VARCHAR(50)=null
      ,@txtValue VARCHAR(50)=null
      ,@status varchar(30))
AS
BEGIN
      SET NOCOUNT ON;
      DECLARE @cmd AS NVARCHAR(max)
      if @txtValue IS NULL  
      Begin
        SET @Value = ''''+@ddlValue+ ''''
        End                
        else if @ddlValue IS NULL  
        begin
        SET @Value = ''''+@txtValue+ ''''
        end
      SET @cmd = 'SELECT ROW_NUMBER() OVER
      (
            ORDER BY C_Register.UserId desc 
      )AS RowNumber

      ,C_Register.UserId, C_Register.Name, C_Register.UserName, C_Register.Status, 
                    Packages.PackagePeriod, Packages.PackageName, C_Register.ActivationDate, 
                      Receive_Payment.OldExpiryDate, Receive_Payment.Balance, Receive_Payment.PyingAmount, 
                      Receive_Payment.LastPaidDate, C_Register.LastUpdateTime, 
                      Area.AreaName, C_Register.MobNo, Employee.EmpName, C_Register.Address,C_Register.CreatedDate

     INTO'+ #Results+'
      FROM C_Register INNER JOIN Receive_Payment ON C_Register.UserId = Receive_Payment.UserId
                       INNER JOIN Area ON C_Register.AreaId = Area.AreaId
                       INNER JOIN Employee ON Receive_Payment.EmpId = Employee.EmpId
                       INNER JOIN Packages ON Receive_Payment.PackageId = Packages.PackageId
     where      C_Register.AccountExpiry= Receive_Payment.OldExpiryDate And C_Register.Status = '+@status+'And
     ' +  @ColumnName + ' = ' + @Value 

      SELECT @RecordCount = COUNT(*)
      FROM #Results

      SELECT * FROM #Results
      WHERE RowNumber BETWEEN(@PageIndex -1) * @PageSize + 1 AND(((@PageIndex -1) * @PageSize + 1) + @PageSize) - 1

      DROP TABLE #Results
      EXEC(@cmd)
END

查询中的问题是临时表的创建，这不是在动态查询中创建临时表的正确方法

但即使在动态查询中创建临时表，也只能在动态查询会话中访问它。如果您尝试选择动态查询外部的临时值，该临时值是在动态查询内部创建的，您将得到一个错误，说明对象不存在

因为您知道动态查询结果中的列数，所以可以在动态查询之外创建临时表，并通过动态查询插入记录

试着像这样改变你的程序

Alter PROCEDURE sp_Get_CustInfoSerach2
(
@PageIndex INT = 1 ,
@PageSize INT = 10 ,
@RecordCount INT OUTPUT ,
@ColumnName VARCHAR(50)=null ,
@Value VARCHAR(50)=null ,
@ddlValue VARCHAR(50)=null ,
@txtValue VARCHAR(50)=null ,
@status varchar(30)
) 
AS 
BEGIN 
SET NOCOUNT ON; 
DECLARE @cmd AS NVARCHAR(max)

If @txtValue IS NULL
Begin 
SET @Value = ''''+@ddlValue+ '''' 
End
Else 
if @ddlValue IS NULL
Begin 
SET @Value = ''''+@txtValue+ '''' 
End 
SET @cmd = 'SELECT ROW_NUMBER() OVER ( ORDER BY C_Register.UserId desc )AS RowNumber,
  C_Register.UserId, C_Register.Name, C_Register.UserName, C_Register.Status, 
                Packages.PackagePeriod, Packages.PackageName, C_Register.ActivationDate, 
                  Receive_Payment.OldExpiryDate, Receive_Payment.Balance, Receive_Payment.PyingAmount, 
                  Receive_Payment.LastPaidDate, C_Register.LastUpdateTime, 
                  Area.AreaName, C_Register.MobNo, Employee.EmpName, C_Register.Address,C_Register.CreatedDate

 INTO #Results
  FROM C_Register INNER JOIN Receive_Payment ON C_Register.UserId = Receive_Payment.UserId
                   INNER JOIN Area ON C_Register.AreaId = Area.AreaId
                   INNER JOIN Employee ON Receive_Payment.EmpId = Employee.EmpId
                   INNER JOIN Packages ON Receive_Payment.PackageId = Packages.PackageId
 where      C_Register.AccountExpiry= Receive_Payment.OldExpiryDate And C_Register.Status = '+@status+'And
 ' +  @ColumnName + ' = ' + @Value 

  /*First Execute above dynamic Sql query */
  EXEC(@cmd)
 /* From the above execute statemnet the query will executed and temporary table will created on the fly */

  SELECT @RecordCount = COUNT(*)
  FROM #Results


  SELECT * FROM #Results
  WHERE RowNumber BETWEEN(@PageIndex -1) * @PageSize + 1 AND(((@PageIndex -1) * @PageSize + 1) + @PageSize) - 1

  DROP TABLE #Results

注意：我为临时表列提供了通用数据类型。请根据您的架构更改日期类型。

我认为您没有将结果变量声明到storedprocedureHow关于不构建SQL-改用参数如何？注意，您的问题与C、paging或GridViews无关。在此查询之前，我创建了相同的查询，但没有引号，所以它正在执行，但在这里，我为pass参数添加了引号，因为coloumnI试图执行相同的ur提到的qury，但再次抛出结果未知错误。因此，我更改如下

ALTER PROCEDURE Sp_get_custinfoserach2 (@PageIndex   INT = 1,
