Database Overload?

Okay.. simple table 20 fields (with a unique ID) 20000000 records

 

your ID is index'd and an autonumber primary field..

you search/link only by ID, not a problem

 

Now lets say you have a 8 inner join linking unindex'd fields using a select in a select..

probably going to get a timeout..

 

okay if they were index'd 8 joins (or even the select in a select by itself) may of killed it anyways but you get the point
