Given PHP similarity to C syntax, google came up with this, amongst others

 

http://www.doc.ic.ac.uk/lab/secondyear/cstyle/cstyle.html

 

 

 

For MySQL, these are my personal ones

[pre]

1 ) Basically, code for readabilty

2 ) Split the query over several lines. Not only is it easier to read

    (without interminable right scrolling) but if Mysql reports an error

    it gives the line number in the query which can help find the error

3 ) Use JOIN .. ON syntax to separate structure from selection criteria

4 ) Use table aliases[/pre]

 

Example

SELECT e.id as Event, e.title,
      ed.eventdate, ed.price,
      p.company
FROM events e
      INNER JOIN eventdates ed ON ed.eventid = e.id
      INNER JOIN eventproducers ep ON e.id = ep.eventid
      INNER JOIN producer p ON ep.producerid = p.producerID
WHERE ed.evendate BETWEEN NOW() AND NOW() + INTERVAL 14 DAT
ORDER BY e.title, ed.eventdate
