mysql：从另一个表插入值

Question

我有3张桌子

Player: player_id, player_name

Date: date_id, date_value

PlayerOnDate: pod_id, player_id, date_id

我怎么能插入类似的东西

INSERT INTO `playerondate`(`player_on_date_id`, `player_id`, `date_date_id`) VALUES (
  NULL,
  SELECT player_id 
    WEHRE player_name LIKE 'aName',
  SELECT date_id 
    WEHRE date_value LIKE '12122015'
)

Answer 1

只需添加一个FROM

SELECT player_id FROM Player WHERE player_name = 'aName',
SELECT date_id FROM `Date` WHERE date_value LIKE '12122015'

Answer 2

您应该使用INSERT ... SELECT语法： http : //dev.mysql.com/doc/refman/5.7/en/insert-select.html

Answer 3

该INSERT INTO ... SELECT有一个特定的SQL语句。

INSERT INTO `playerondate`(`player_on_date_id`, `player_id`, `date_date_id`)
SELECT NULL, player_id, date_id 
FROM playerondate
WHERE player_name = 'aName' AND date_value LIKE '12122015'
