mysql - Can I use two 'JOIN's in a single call? -
i'm trying call 3 different tables @ once.
table a
has general data.
table td
& dmd
have specific data data points.
my call (simplified) looks this.
select a.*, td.*, dmd.* activities a, tweet_activity_data td, direct_message_activity_data dmd a.activity_id in (1,2,3,4,5) , a.activity_id = dmd.id , a.activity_id = td.tweet_id
those last 2 lines i'm having trouble think.
i need things line in response , produces no results.
am 'allowed' use 2 joins in sql call?
yes, join tables use join , on keyword. specifically, stuff in clause end on clauses, telling query how join tables. query
select a.*, td.*, dmd.* activities join tweet_activity_data td on a.activity_id = td.tweet_id join direct_message_activity_data dmd on , a.activity_id = dmd.id a.activity_id in (1,2,3,4,5)
