That's definitely something you wouldn't want to do very often. It's impractical and extremely inefficient.

Subject: Re: SELECT FROM 2 or more tables
A join merges every record in one table with every record in another table, which is something you rarely want to do. So you want to set a filter on the merged records, which can be anything, but is usually a match between a field in one table and a field in another table.
That's a join in two sentences or less.
