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

首先，我得到： Incorrect syntax near the keyword 'AS'.

所以，我删除了这个并用带有完整表名的别名替换，这给了我： Incorrect syntax near the keyword 'INNER'.

我发现了question这是我发现INNER JOIN的地方，但是SQL Server没有正确解析它。有什么想法吗？

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

你错过了top语句后的tablename / alias。
