无法重新打开表mysql

我执行了以下过程，该过程说明无法重新打开表为什么会出现此错误。以下是查询：

DECLARE rangee INT;
DECLARE uid BIGINT;

SET @rangee = plimitRange * 10; 
SET @uid    = puserid;

DROP TEMPORARY TABLE IF EXISTS Rangee;
CREATE TEMPORARY TABLE Rangee(max BIGINT,min BIGINT);

PREPARE STMT FROM
'INSERT INTO Rangee
select max(postid),MIN(postid) from
(
select wall.postid from wall,posts where  
wall.postid = posts.postid and posts.userid=?
order by wall.postid desc LIMIT 10 OFFSET ?
)m;
';

 EXECUTE STMT USING @uid,@rangee;
 DEALLOCATE PREPARE STMT;


 select comments.comment,comments.postid,user.name,comments.userid 
 from user,posts,comments where 
 posts.postID = comments.postid and 
 comments.postid<=(select max from Rangee) and 
 comments.postid>=(select min from Rangee) and posts.userid = puserid and 
 user.userid=comments.userid order by comments.postid desc;

在这里，我在另一个表的临时表中插入值min和max id，以便在最终查询中使用这些值检索我的数据。但是在最终查询中，我指定了范围，即包含select max from range和select min from range的行出现了此错误。我如何解决此问题。的值min和max恢复得很好

<UPDATE>

然后忘掉整个过程，在一个查询中完成：

select comments.comment,comments.postid,user.name,comments.userid 
 from 
 user
 INNER JOIN comments ON user.userid=comments.userid
 INNER JOIN posts ON posts.postID = comments.postid
 WHERE 
 comments.postid <=  
 (select MAX(postid) from
    (
    select wall.postid from wall,posts where  
    wall.postid = posts.postid and posts.userid=?
    order by wall.postid desc LIMIT 10 OFFSET ?
    )sq1
 )

 and 
 comments.postid >= 
 (select MIN(postid) from
    (
    select wall.postid from wall,posts where  
    wall.postid = posts.postid and posts.userid=?
    order by wall.postid desc LIMIT 10 OFFSET ?
    )sq2
 ) 
 and 
 posts.userid = puserid 
 order by comments.postid desc;

就这样

</UPDATE>

旧答案

DECLARE rangee INT;
DECLARE uid BIGINT;

SET @rangee = plimitRange * 10; 
SET @uid    = puserid;

PREPARE STMT FROM
'select @max_postid := MAX(postid), @min_postid := MIN(postid) from
(
select wall.postid from wall,posts where  
wall.postid = posts.postid and posts.userid=?
order by wall.postid desc LIMIT 10 OFFSET ?
)m;
';

 EXECUTE STMT USING @uid,@rangee;
 DEALLOCATE PREPARE STMT;


 select comments.comment,comments.postid,user.name,comments.userid 
 from user,posts,comments where 
 posts.postID = comments.postid and 
 comments.postid<=@max_postid and 
 comments.postid>=@min_postid and posts.userid = puserid and 
 user.userid=comments.userid order by comments.postid desc;

你根本不需要临时的桌子。另外，做评论也是不好的。postid thnx的答案@tombom我已经试过了，效果很好，但问题是它会返回我不想要的两个结果。我只需要上一次查询的结果。prepare语句中的select将返回一个结果，然后我的最终查询将返回另一个结果。我明白了。更新了我的答案。不要担心，因为查询看起来很复杂。它不一定会跑得更慢或其他什么。MySQL的优化器做得很好，可以检测子查询何时重复，但差异很小。它给出了以下错误：每个派生表都必须有自己的别名。@MJ192现在应该可以工作了。子查询缺少一个别名，仅此而已。thnx很多。这几天来我一直在坚持。
