我有一个如下所示的SQL表：
if player_card == 'Jack' or player_card == 'jack':
player_card = 11
elif player_card == 'Queen' or player_card == 'queen':
player_card = 12
elif player_card == 'King' or player_card == 'king':
player_card = 13
elif player_card == 'Ace' or player_card == 'ace':
player_card = 14
else:
player_card = int(player_card)
我想计算每行的id | value
-----------------------
1 | 5
2 | 5
3 | 6
。
在此示例中，输出应为value。
我应该使用什么查询来计算行的总值？
