nhibernate按id列表删除多条记录'；使用CreateQuery进行查询

我正试图从表A中删除表B中ID列表中存在的多条记录，如下所示：

List<ulong> ids = new List<ulong> {1, 2};

string deleteQuery = string.Format(
                @"DELETE FROM TABLE_A WHERE EXISTS 
                (SELECT id FROM TABLE_B WHERE checkpoint_id IN :idList)");

Session.CreateQuery(deleteQuery).SetParameterList("idList", ids).ExecuteUpdate();

如果我把列表硬编码[在（1,2）]，它会工作。 我错过了什么？

发现了问题：

我需要一个额外的括号：idList

string deleteQuery = string.Format(
            @"DELETE FROM TABLE_A WHERE EXISTS 
            (SELECT id FROM TABLE_B WHERE checkpoint_id IN (:idList))");

string deleteQuery = string.Format(
            @"DELETE FROM TABLE_A WHERE EXISTS 
            (SELECT id FROM TABLE_B WHERE checkpoint_id IN (:idList))");
