Question

我使用executeWIthArray（）来传递列表。但是，当我尝试在Query中使用此数组时，它显示错误。这是我的代码

QueryHelper.setSortOrderZero(pm).executeWithArray(list);

在QueryHelper中，我已经定义了函数setSortOrderZero，如下所示：

public static Query setSortOrderZero(PersistenceManager pm) {
final Query query =  pm.newQuery("javax.jdo.query.SQL","update TABLENAME set SORTORDER = 0 where ID in list");

return query;

}

但是我得到了错误。这是访问数组的正确方法????

如上所述，在SQL a＆＃34;参数＆＃34;必须是＆＃34;？＆＃34;在查询中;你没有参数，所以没有点传递一些参数数组。更有意义的是

q = pm.newQuery("javax.jdo.query.SQL", "update TABLENAME set SORTORDER = 0 where ID in ?");
List values = ...
q.execute(values);

如何在sql Query中使用从executeWithArray（Object []）传递的数组
