hibernate中SQL包含冒號

當前負責的項目使用的是hibernate，而“：”是hibernate的一個占位符，作為預編譯使用的，

select tmp.pid from  
(select pid, loginTime, @i := @i + 1 i from gms_record_login_game, (select @i := 0) r order by pid, loginTime) tmp
LEFT JOIN
(select pid, loginTime, @j := @j + 1 k from gms_record_login_game, (select @j := 0) r1 order by pid, loginTime) tmp2 
on tmp.i + 1 = tmp2.k and tmp.pid = tmp2.pid 
WHERE  TIMESTAMPDIFF(DAY,DATE_FORMAT(tmp.loginTime,'%Y-%m-%d'),DATE_FORMAT(tmp2.loginTime,'%Y-%m-%d'))>3 
GROUP BY tmp.pid

使用HQL查詢時報錯：Query query = session.createQuery(HQL);

QueryException: unexpected char: '@' 

原因：HQL不支持這種查詢

解決方案：使用原生SQL查詢時報錯：SQLQuery query = session.createSQLQuery(SQL);

Space is not allowed after parameter prefix ':'

原因：這是hibernate3.X包之下的一個bug,(參照 id=41741)在hibernate4.X中已經修復。

解決方案：需要對雙冒號進行轉義，在使用雙反斜杠進行轉義

select tmp.pid from  
(select pid, loginTime, @i \\:= @i + 1 i from gms_record_login_game, (select @i \\:= 0) r order by pid, loginTime) tmp
LEFT JOIN
(select pid, loginTime, @j \\:= @j + 1 k from gms_record_login_game, (select @j \\:= 0) r1 order by pid, loginTime) tmp2 
on tmp.i + 1 = tmp2.k and tmp.pid = tmp2.pid 
WHERE  TIMESTAMPDIFF(DAY,DATE_FORMAT(tmp.loginTime,'%Y-%m-%d'),DATE_FORMAT(tmp2.loginTime,'%Y-%m-%d'))>3 
GROUP BY tmp.pid　

重點來了修改后依舊沒有解決！！！！

后來在stackoverflow看到有人回復

Another solution for those of us who can't make the jump to Hibernate 4.1.3.
Simply use /*'*/:=/*'*/ inside the query. Hibernate code treats everything between ' as a string (ignores it). MySQL on the other hand will ignore everything inside a blockquote and will evaluate the whole expression to an assignement operator.
I know it's quick and dirty, but it get's the job done without stored procedures, interceptors etc.

修改后

select tmp.pid from  
(select pid, loginTime, @i /*'*/:=/*'*/ @i + 1 i from gms_record_login_game, (select @i /*'*/:=/*'*/ 0) r order by pid, loginTime) tmp
LEFT JOIN
(select pid, loginTime, @j /*'*/:=/*'*/ @j + 1 k from gms_record_login_game, (select @j /*'*/:=/*'*/ 0) r1 order by pid, loginTime) tmp2 
on tmp.i + 1 = tmp2.k and tmp.pid = tmp2.pid 
WHERE  TIMESTAMPDIFF(DAY,DATE_FORMAT(tmp.loginTime,'%Y-%m-%d'),DATE_FORMAT(tmp2.loginTime,'%Y-%m-%d'))>3 
GROUP BY tmp.pid　　

問題解決
