Php/mysql autoincrement

1

i have a 2 column table in mysql, NEWS_ID and NEWS_CONTENT… but when i save something in the database, it is not in order… not 123 but 132465…etc… why???

why is it when i post news, the arranngement is random?

im new to mysql/php…

the code to adding is similar to this:


//execute / add
if(!mysql_query(sprintf($addSt,$HTTP_POST_VARS['content']), $link)){
	DisplayError(sprintf("Error in executing %s statement", $addSt));
	DisplayError(sprintf("error: %d %s", mysql_errno($link), mysql_error($link)));
	exit();
}
else
{
	echo "<center><BR><b>...Yes! Successfully added the entry to $news_table.</b></center>";
}

thanks
