Yeah, there are lots of good examples... I was just trying to come up with the very simplest query that would demonstrate the problem.

Honestly, single-table queries aren't likely to be all that problematic, no matter what. You do a full table-scan on a million-row table... well, that's 5 seconds you wish you hadn't spent, but it's not gonna totally kill you, unless it is being hit with great frequency. It's really when you get into large, complicated plans involving lots of joins and various other nasties, that tuning gets to be really critical (except, of course, for very frequently accessed queries).

Somebody could write a whole book on database tuning... oh, wait... several people already have :-P

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
