Is there a comprehensive online document or printed book that explains
the EXPLAIN output? Something akin to the MySQL documentation here:
http://dev.mysql.com/doc/refman/5.1/en/explain-output.html
I would really like to know what EXPLAIN is telling me, and more
importantly, what it is not telling me. I have read some documents,
but none that breaks it down to pieces and explains each piece
separately.
TIA.
