Lautarox Posted November 1, 2010 Share Posted November 1, 2010 I'm building a facebook application, as it is intendeed to reach to a big ammount of users, I'm worried about the performance of it, I'm querying facebook to get user's friends and then I'm searching for each of them in a mysql database, what would you recommend me to do? Is it better to perfom separated querys looking for each user or should I make a query looking for all the users, something like, SELECT * FROM table WHERE id=id1 AND id=id2 ... Thanks in advance Quote Link to comment Share on other sites More sharing options...
snowman15 Posted November 8, 2010 Share Posted November 8, 2010 I would gather all the ID's your looking for in an array, then use a loop to build an sql statement with lots of 'id=id1 OR' (then repeat) and do one single query. Quote Link to comment Share on other sites More sharing options...
