我的语法有什么问题？

Question

WHILE @@ROWCOUNT <> 0 
BEGIN 
    CHECKPOINT; 
    DELETE TOP (300000) 
     FROM [dbo].[Event] AS E 
    INNER JOIN #tempEvents AS TE 
     ON E.[EventID] = TE.[EventID] 
END 

对于初学者来说，我得到： Incorrect syntax near the keyword 'AS'.

所以，我删除这一点，并与全表名别名代替，这给了我： Incorrect syntax near the keyword 'INNER'.

我发现这个question这是我发现了关于做INNER JOIN，但SQL Server不正确解析此。有任何想法吗？

试试这个：

WHILE @@ROWCOUNT <> 0 
BEGIN 
    CHECKPOINT; 
    DELETE TOP (300000) E 
     FROM [dbo].[Event] AS E 
    INNER JOIN #tempEvents AS TE 
     ON E.[EventID] = TE.[EventID] 
END 

你无缘语句后的tablename /别名。
