答案 0 :(得分：0)
SQLite异常，指示SQL解析时出错 或执行。
Exception java.lang.Throwable: android.database.sqlite.SQLiteException: no such table: ProductsDrafts (code 1): , while compiling: select * from ProductsDrafts
确保数据库中存在 ProductsDrafts 。
<强> FYI
如果您在发布后添加表格，请添加onUpgrade()
需要升级数据库时调用。实施 应该使用此方法删除表，添加表或执行任何其他操作 它需要升级到新的架构版本。
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)
{
if(newVersion>oldVersion)
// ALTAR TABLE STATEMENT
// DROP TABLE STATEMENT
}
