mysql query results sorting
I am calling the results form a query to a list on my site based on if the item is "downtown_hosted". This works fine but I would now like to sort that list DESC, but can't seem to get the syntax correct.
Below is what I have:
$result_events = mysql_query("SELECT * FROM events
开发者_开发问答 WHERE downtown='downtown_hosted'
ORDER BY date DESC
LIMIT 5 ");
You need to escape the word "date" with backticks.
E.g.:
$result_events = mysql_query("
SELECT * FROM events
WHERE downtown='downtown_hosted'
ORDER BY `date` DESC
LIMIT 5
");
In practice it's not a bad habit to get into always enclosing your columns with backticks, so you will not have to worry about conflicting with language keywords.
date
is an SQL keyword. You can have a column called date
, but every time you refer to it you will have to use identifier quotes. In MySQL this is accomplished using backticks: `date`
