Question

我的应用程序工作正常，但是当我们第一次升级时，它会显示我们在Google Play中的堆栈跟踪中出现的错误。

我的代码：

public Cursor getContentData(String pc, String sc) {

        return database.rawQuery("SELECT * FROM content where pc=" + pc
                + " and sc=" + sc + "", null);
    }

错误

Answer 1

正如您的错误在线下所示：

引起：java.lang.IllegalStateException：从第0行获取字段槽第16栏失败

可能第17列是您的数据库查询语句中缺少的一些内容。

java.lang.IllegalStateException：从第0行col 16获取字段槽失败
