Question

我正在使用queryBuilder以及在哪里进行选择。这是一个POJO表，一般来说很长一段时间以来一直很好地适用于许多用户。

ArrayList<X> result = new ArrayList<X>();
QueryBuilder<X, Integer> queryBuilder = getXDao().queryBuilder();
Where<X, Integer> where = queryBuilder.where();
where.eq(X, x);
queryBuilder.orderBy(X, true);

result = (ArrayList<X>)getXDao().query(queryBuilder.prepare());

由于以下ORMLite异常，每次查询此表时都会有一个特定的崩溃：

java.lang.IllegalStateException: Couldn't read row 1060, col 0 from CursorWindow.  Make sure the Cursor is initialized correctly before accessing data from it.

我已经在文档中看到过，对于中型或大型表，使用迭代器可能更好。我的问题是这个数字或行是否会被视为“中等或大”。我原以为不会。我也是创建大于此的表而不会发现此问题

是否有人建议可能导致此问题或之前看到过类似情况？可能是错误的数据？

当有许多记录时，ORMLite IllegalStateException
