query.setLockMode（「A」，lockMode.upgrade_skiplocked）給出了休眠

我試圖取代我的SQL查詢是Oracle警告，這是因爲：query.setLockMode（「A」，lockMode.upgrade_skiplocked）給出了休眠

select trim(a.id) as id from tbl_insttype a where a.chi_city='1' order by cast(a.id as int) for update skip locked

以下是等效替代冬眠：

Query query=session.createQuery("select trim(a.id) as id from TblInsttype a where a.chiCity='1' order by cast(a.id as int) "); 
    query.setLockMode("a",LockMode.UPGRADE);

但我的日誌警告說，

LOG：

說一些明確的話，我沒有得到它的權利。下面的SQL查詢也沒有任何更新跳過鎖定在它。

我沒有得到我在做錯什麼，我應該嘗試一些其他的事情嗎？ PLUS 它給不同的鎖模式相同的錯誤。

還在等待回覆!!!它已經兩個小時，只有10個意見:( –

什麼版本的Hibernate？ – Naros

我使用4.3，並且也嘗試過5.0，但在這兩個版本中都是同樣的東西。 –

它說Alias-specific lock modes requested, which is not currently supported with follow-on locking，所以我認爲你應該嘗試它沒有與a別名你的表。（只有一張桌子，是否需要？）

https://docs.jboss.org/hibernate/orm/ 3.5/javadocs/org/hibernate/Query.html。這裏的javadoc只有一個setLockMode（）方法，它與alias.cant跳過別名 –

後續鎖定意味着什麼，無法在Internet上找到任何東西？ –

query.setLockMode（「A」，lockMode.upgrade_skiplocked）給出了休眠
