您不能指定目標表「rinexo」在FROM子句

Question

此查詢的輸出讓我重複表中的行更新，

select * from rinex1 where rid not in 
    (select min(rid) from rinex1 group by rinex_version,type); 

現在我希望他們使用此查詢，刪除，

delete from rinex1 where rid not in 
    (select min(rid) from rinex1 group by rinex_version,type); 

它提供了以下錯誤說：

您不能指定目標表 'rinexo' 的更新在FROM子句

我該怎麼辦？

嘗試，

DELETE FROM rinex1 
WHERE rid NOT IN 
    (SELECT MIN(rid) 
    FROM rinex1 
    GROUP BY rinex_version, type 
    ) AS p ;
