Hello!
I\'ve been trying to optimize a few of my queries in a program I wrote but I\'m getting a little lost. Here is a half written SQL query:
$sql = \'SELECT e.id, e.posterid, e.titletext, m.username\'
. \' FROM phpnews_news e, phpnews_posters m\'
. \' WHERE e.posterid = m.id\'
. \' ORDER BY e.id DESC\';
$SQL_query = mysql_query($sql);
while ($posts = mysql_fetch_array($SQL_query))
{
// Do stuff
}
My tables are like so:
phpnews_news table holds all the news.
phpnews_posters table holds people allowed post news.
The name of the person who posts the news is in the phpnews_posters table. A foreign key, \"posterid\" is used to link them to an article. There\'s also a field called \"postername\" that stores the postersname in the phpnews_news table in case that particular news poster is deleted.
So, as you can see I am able to get the posters name from the phpnews_posters table, but I don\'t know how to use the \"postername\" field from phpnews_news if there is no matching ID in the posters table.
So basically if this isn\'t true:
. \' WHERE e.posterid = m.id\'
Any help is greatly appreciated! You\'d be helping me make an Open Sorce project better by helping me here!
Thanks!
