I am working in android with five rows in my table; _id, title, type, platform, body. I have some rows that have null Columns, the _id is an auto increment field so it will never be null.
我面临的问题是,除 _外,我不能删除已经创造的无价值之行。
Here is what have tried: public boolean deleteBlankRecord(long rowId) {
return mDb.delete(DATABASE.TABLE,KEY_TITLE + "=" + title, null) > 0;
没有人会说什么?
我认为你对删除职能如何发挥作用的误解。 尝试使用_id来删除。
return mDb.delete(DATABASE.TABLE,KEY_ID + "=" + rowId, null) > 0;
