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

Question

我正在使用 executeWIthArray() 传递列表。但是当我尝试在查询中使用这个数组时，它显示 error.This 是我的代码

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

我在 QueryHelper 中定义了函数 setSortOrderZero 如下：

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 error.So 这是访问数组的正确方法吗？？？？

如前所述，在 SQL 中，"parameter" 必须是“?”在查询中；你没有参数，所以没有必要传入一些参数数组。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);
