Sql 使用insert into时，存储过程中的对象名称无效

编辑：

我有两个表，表1和表2由GUID链接，我想在表2中搜索不在表1中的任何GUID并插入它们

我正试图在select from where语句中使用insert，如下所示：

insert into WebCatalog.Published.DemoTracking (RCompanyLink, Purchased, DemoDate)
Select RC.Link, Purchased = 0, DemoDate = GETDATE()
from WebCatalog.Published.RCompany RC
where RC.Link != WebCatalog.Published.DemoTracking.RCompanyLink and RC.DemoLicense = 1

当对象名在存储过程中且多部分标识符无法绑定到引用时，我不断收到一个无效的对象名错误

WebCatalog.Published.DemoTracking.RCompanyLink

当我试图自己执行它时出错

我的语句格式是否不正确？

而不是

 RC.Link != WebCatalog.Published.DemoTracking.RCompanyLink 

使用

完整代码

INSERT INTO webcatalog.published.demotracking 
            (rcompanylink, 
             purchased, 
             demodate) 
SELECT RC.link, 
       Purchased = 0, 
       DemoDate = Getdate() 
FROM   webcatalog.published.rcompany RC 
WHERE  RC.link NOT IN (SELECT rcompanylink 
                       FROM   webcatalog.published.demotracking) 
       AND RC.demolicense = 1

问题是，在SQL中，您必须告诉服务器数据是如何关联的；它并不是自动推断出来的。您所拥有的看起来可能在orm中工作，并使用Linq2Sql（一种.Net技术）

我建议使用NOT EXISTS，因为我相信它比中的性能更好

INSERT INTO webcatalog.published.demotracking 
            (rcompanylink, 
             purchased, 
             demodate) 
SELECT RC.link, 
       Purchased = 0, 
       DemoDate = Getdate() 
FROM   webcatalog.published.rcompany RC 
WHERE  NOT EXISTS (SELECT *
         FROM   webcatalog.published.demotracking dt WHERE dt.rcompanylink = RC.link) 
       AND RC.demolicense = 1 

INSERT INTO webcatalog.published.demotracking 
            (rcompanylink, 
             purchased, 
             demodate) 
SELECT RC.link, 
       Purchased = 0, 
       DemoDate = Getdate() 
FROM   webcatalog.published.rcompany RC 
WHERE  NOT EXISTS (SELECT *
         FROM   webcatalog.published.demotracking dt WHERE dt.rcompanylink = RC.link) 
       AND RC.demolicense = 1
