抛出错误：

列名称'#Results'无效。

如何解决？

Answer 1

如果我正确理解你的问题，你应该在从临时表中选择之前先执行动态sql

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

您的查询中的问题是创建临时表，这不是在dynamic query内创建临时表的正确方法。

但即使您在temp table内创建dynamic query，也只能accessed session dynamic query。如果您尝试在动态查询中创建的动态查询之外选择临时值，则会收到错误消息，指出对象不存在。

由于您知道动态查询结果中存在的列数，因此您可以在动态查询之外创建temp table，并通过动态查询创建insert记录。

尝试更改您的程序。

ALTER PROCEDURE Sp_get_custinfoserach2 (@PageIndex   INT = 1, 
                                        @PageSize    INT = 10, 
                                        @RecordCount INT output,

        END 
/*create a temp as same structure of your dynamic query select statement*/

      SET @cmd =

    SELECT @RecordCount = Count(*)

    SELECT *

                                 @PageSize ) - 1 

    DROP TABLE #results 

    EXEC(@cmd) 
END

注意：我已将通用datatypes提供给temp表格列，请根据您的datetypes更改schema。

列名称“#Results”无效
