sql insert multiple rows with inner selects - mysql

Question

I need to insert multiple rows , but some of the data have to come from inner select
i having problem to construct the right sql statement for example i have :
insert into game_friends(
game_users_id,
game_users_id_name,
created_to_app_users_id,
created_to_app_users_id_name
) VALUES ......
now the problematic part is that the created_to_app_users_id_name and game_users_id_name i can get only by using select like this:
SELECT app_users_game_users_id_name
FROM `app_users` WHERE app_users_game_users_id = $game_users_id
and
SELECT app_users_created_to_app_users_id_name
FROM `app_users`
WHERE app_users_created_to_app_users_id = $created_to_app_users_id
how can i combine it to one sql statement using mysql
UPDATE:
Thanks to all for answering , but i guess didnt explain my problem right ...
i need to insert multiple rows that means i will have like 5-7 game_users_id coming
and it needs in the end look like ( with out the select here .. )
insert into game_friends(
game_users_id,
game_users_id_name,
created_to_app_users_id,
created_to_app_users_id_name
)
VALUES
($game_users_id, app_users_created_to_app_users_id_name, $created_to_app_users_id,app_users_created_to_app_users_id_name ),
($game_users_id, app_users_created_to_app_users_id_name, $created_to_app_users_id,app_users_created_to_app_users_id_name ),
($game_users_id, app_users_created_to_app_users_id_name, $created_to_app_users_id,app_users_created_to_app_users_id_name ),
($game_users_id, app_users_created_to_app_users_id_name, $created_to_app_users_id,app_users_created_to_app_users_id_name );
where each Values entry need to be composed from select.

Answer 1

try this code for PHP:
$query = "insert into game_friends(
game_users_id,
game_users_id_name,
created_to_app_users_id,
created_to_app_users_id_name
) SELECT
app_users_game_users_id,
app_users_game_users_id_name,
app_users_created_to_app_users_id,
app_users_created_to_app_users_id_name
FROM `app_users` WHERE
app_users_game_users_id = $game_users_id
AND
app_users_created_to_app_users_id = $created_to_app_users_id";

Answer 2

this is UNTESTED.
insert into game_friends
(
game_users_id,
game_users_id_name,
created_to_app_users_id,
created_to_app_users_id_name
)
VALUES
SELECT game_users_id,
created_to_app_users_id,
FinalTable.game_users_id_name,
FinalTable.created_to_app_users_id_name
FROM
((SELECT app_users_game_users_id as game_users_id,
app_users_game_users_id_name as game_users_id_name
FROM app_users
WHERE app_users_game_users_id = game_users_id) as iGameID
INNER JOIN
(SELECT app_users_created_to_app_users_id as created_to_app_users_id,
app_users_created_to_app_users_id_name as created_to_app_users_id_name
FROM app_users
WHERE app_users_created_to_app_users_id = created_to_app_users_id) as iCreatedID
ON iGameID.game_users_id = iCreatedID.created_to_app_users_id) as FinalTable

Simple SELECT over two tables without any JOINs should do the trick (assuming each select statement returns only one row):
INSERT INTO game_friends (
game_users_id,
game_users_id_name,
created_to_app_users_id,
created_to_app_users_id_name
)
SELECT u_game.app_users_game_users_id,
u_game.app_users_game_users_id_name,
u_created.app_users_created_to_app_users_id,
u_created.app_users_created_to_app_users_id_name
FROM `app_users` u_game,
`app_users` u_created
WHERE u_game.app_users_game_users_id = $game_users_id
AND u_created.app_users_created_to_app_users_id = $created_to_app_users_id
Another note: I am guessing that you app_users table does really have a column app_users_game_users_id or app_users_created_to_app_users_id. In which case you should replace those in the SQL with the real column name, which again I guess is either user_id, app_user_id or id. It is just that your model looks very strange otherwise assuming that both of the above mentioned columns are supposed to be unique in the table.
