我有一个有线情况。下面的代码在一台服务器上运行良好，但在另一台服务器上运行良好。两台服务器上的数据库兼容性级别相同。我使用 sql server 2016。

;USE MyDB;
GO
--exec MyDB.dbo.sp_Cleanup_Bid5YearData
ALTER PROCEDURE dbo.sp_Cleanup_Bid5YearData

AS 

DECLARE @date VARCHAR(10), 
        @cmdIf NVARCHAR(200),
        @cmd NVARCHAR(4000)

SET @date = CAST(YEAR(GETDATE()) AS VARCHAR(4)) + '_' + CAST(MONTH(GETDATE()) AS VARCHAR(2)) + '_' + CAST(DAY(GETDATE()) AS VARCHAR(2)) 

IF OBJECT_ID('tempdb..#Id_ToBeRemoved') IS NOT NULL --SELECT 1

   DROP TABLE #Id_ToBeRemoved;

CREATE TABLE #Id_ToBeRemoved
    (
        Id INT PRIMARY KEY NOT NULL, 
        Code CHAR(3) NOT NULL 
    );

INSERT INTO #Id_ToBeRemoved (Id, Code)
VALUES(12,'TMB'),
      (13,'FGR');

IF EXISTS (SELECT TOP 1 1 FROM #Id_ToBeRemoved) 

SET @cmd = ('

;USE MyDB;

IF EXISTS (SELECT 1 FROM [MyDB].dbo.Table_5YearData_'+@date+') 

    DROP TABLE [MyDB].dbo.Table_5YearData_'+@date+';

;USE MyDB;

SELECT 
    Id, 
    Code
INTO [MyDB].dbo.Table_5YearData_'+@date+'
FROM  #Id_ToBeRemoved; 
         ')

EXEC sp_executesql @cmd;
--EXEC (@cmd);
--select * from  [MyDB].dbo.Table_5YearData_2018_4_25 -- you may need to change the ending of the table "2018_4_25" depending on the date you run this statement

我收到的错误消息是：

消息 208，级别 16，状态 1，第 7 行
无效的对象名称“bidNotification.dbo.Table_5YearData_2018_4_25”

表 bidNotification.dbo.Table_5YearData_2018_4_25 在您的第二个数据库中不存在。您的查询检查表中是否有行而不是表是否实际存在。仅当该表已存在时，您的查询才有效。

您可以修改并执行此操作OBJECT_ID()来验证表是否存在。

SET @cmd = ('

;USE MyDB;

IF OBJECT_ID(N''[MyDB].dbo.Table_5YearData' + @date + ''', N''U'') IS NOT NULL

    DROP TABLE [MyDB].dbo.Table_5YearData_'+@date+';

;USE MyDB;

SELECT 
    Id, 
    Code
INTO [MyDB].dbo.Table_5YearData_'+@date+'
FROM  #Id_ToBeRemoved; 
         ')
