要在数据库中删除第N条记录后的所有记录,你可以使用以下步骤来实现:
SQLiteDatabase db = dbHelper.getWritableDatabase();
int idToDelete = 5; // 要删除的记录的ID
String whereClause = "ID = ?";
String[] whereArgs = new String[] { String.valueOf(idToDelete) };
db.delete("your_table_name", whereClause, whereArgs);
String selectQuery = "SELECT * FROM your_table_name WHERE ID > ?";
String[] selectionArgs = new String[] { String.valueOf(idToDelete) };
Cursor cursor = db.rawQuery(selectQuery, selectionArgs);
if (cursor.moveToFirst()) {
do {
int id = cursor.getInt(cursor.getColumnIndex("ID"));
String name = cursor.getString(cursor.getColumnIndex("name"));
// 处理每条记录
} while (cursor.moveToNext());
}
cursor.close();
完整的示例代码如下所示:
SQLiteDatabase db = dbHelper.getWritableDatabase();
int idToDelete = 5; // 要删除的记录的ID
String whereClause = "ID = ?";
String[] whereArgs = new String[] { String.valueOf(idToDelete) };
db.delete("your_table_name", whereClause, whereArgs);
String selectQuery = "SELECT * FROM your_table_name WHERE ID > ?";
String[] selectionArgs = new String[] { String.valueOf(idToDelete) };
Cursor cursor = db.rawQuery(selectQuery, selectionArgs);
if (cursor.moveToFirst()) {
do {
int id = cursor.getInt(cursor.getColumnIndex("ID"));
String name = cursor.getString(cursor.getColumnIndex("name"));
// 处理每条记录
} while (cursor.moveToNext());
}
cursor.close();
请注意,上述示例假设你已经创建了一个名为"your_table_name"的表,并且该表包含ID和name列。你需要根据自己的数据库结构进行相应的更改。
