SQLite使用rowid删除行不起作用

问题描述

我创建了一个SQL查询，以删除给定rowid的行。当我运行查询时，没有错误，但是，该行不会被删除。

AND NOT (business_desk ='D_ONE' AND FLOW = 'D1' and DEST_DESK = 'DELTA')
AND (business_desk !='D_ONE' AND FLOW != 'D1' and DEST_DESK != 'DELTA')

解决方法

尝试一下：

String query = "DELETE FROM " + TABLE_NAME + " WHERE rowid " + " = '" + id + "'";
db.execSQL(query);

但是我个人更喜欢这种方式：

if (db.delete(TABLE_NAME,rowid+ " = ?",new String[]{id}) != 0) {
    Log.i("row","Has been deleted");
} else{
    Log.i("row","Has not been deleted");
}

,

解决方案：我使用了vacuum功能来重新生成正确的rowId。我以前曾删除过rowId不存在的行。
