I think you probably should do it like this.
SELECT *
FROM announcements
WHERE announcements_expiredate > CURDATE()
AND announcements_postdate <= CURDATE()
ORDER BY announcements_expiredate ASC
Otherwise they won't show till after the postdate. I assume you want to
display them on the post date and not the next day? This of course
assumes your field is of type 'date' and not 'datetime'.
Prefixing the field name with the table name is not needed unless you
have a join with a table with the same field names. Based on your field
naming method it appears as though that won't happen. If it does, it is
much less to type and easier to read if you alias the table name. like
this......
SELECT *
FROM announcements a
WHERE a.announcements_expiredate >CURDATE()
AND a.announcements_postdate<=CURDATE()
ORDER BY a.announcements_expiredate ASC
also it is a good habit to get into to have all filed and table names
enclosed in back ticks just in case you have field names that are sql
reserved words or otherwise would confuse MySQL.
SELECT *
FROM `announcements` a
WHERE a.`announcements_expiredate` >CURDATE()
AND a.`announcements_postdate` <= CURDATE()
ORDER BY a.`announcements_expiredate` ASC
Also to me it just makes it easier to read/ understand if you second
condition is rewritten like this...
AND CURDATE() >= announcements_postdate
Just my opinion on that.
