AUTO_INCREMENT working
Can anybody tell me how AUTO_INCREMENT works in MySQL especially when we are using DB Replications. At times I get duplicate key error though taken care that the insertions and updations are done in the master db.
MIXING MYISAM AND INNODB
I'm using multiple dbs for my very high traffic multiple sites. One of my db (say parentDb) just maintains users who can login to all the sites. Others are sites specific dbs(say childDbs). I'm using INNODb tables for my parentDb while my childDbs tables are of MyISAM type. Some code does have direct joins with between parentDb and childDb. Is it good to use this kind of mixture? Can it create problems in future? __ Do you Yahoo!? Yahoo!

using IN()
I've a bunch of IDs fetched(around 60,000) from a DB. I'm using these IDs to fetch data from another DB having a related fields in its tables. I'm using IN clause for it. i.e. for e.g. SELECT * FROM site_users WHERE parentUserId IN (1,2,3,4) Again here parentUserId is Indexed. The query is running fine for now. I wanted to know how MySQL interprets and executes this query and can it have problems in future if number exceeds 60,000?? __ Do you Yahoo!?
