delete across multiple tables problem
I'm trying to help a friend with this. When I run this everything is fine SELECT * from clicks, urls WHERE clicks.url=urls.url AND urls.description IS NULL The clicks table has 31 instances of url that match 5 instances of url in the urls table. When I run the following I get a syntax error DELETE * from clicks, urls WHERE clicks.url=urls.url AND urls.description IS NULL What am I doing wrong?

MySQL - PHP - Banner ad click through tracker
Does anyone here have a PHP script that will store banner ad click throughs in a MySQL database? If not, is anyone here interested in doing this project?

MySQL counter for HIGH traffic site
I'm needing counter for site that receives 80 to 120 hits a minute at peak load. Many I have tried cause excessive server load and need to be deactivated or they lose data and return to zero without warning. All tried so far have been written in Perl writing to a file. Anyone here know of a counter that would handle HIGH traffic with little added server load? Would using MySQL to store count be of any benifit? Would Perl or PHP be faster for writing count to MySQL?

MySQL - check for existing data
I have a db table that receives weather data several times a day via a php script and cron job. Sometimes the data is duplicated for a certain time window. 11:50 44 degree 11:50 44 degree 11:40 45 degree 11:30 46 degree 11:20 46 degree 11:10 45 degree I do not want the duplicate data for the 11:50 time slot to be inserted into my table. Is there a common method used to check if data already exists in a db table and if so to cancel the data insertion? What is this called? Is this demonstrated in the MySQL book or documentation. If I knew what this was called, I might have better luck finding solution.

mysql php - while loops
The following lists 12 items from a fruits table.
$results = mysql_query(SELECT ID, date, appleprice, orangeprice, pearprice
FROM fruits);
while ($data = mysql_fetch_array($results))
{
?
p?=$data[date]? - ?=$data[appleprice]? -
?=$data[orangeprice]? - ?=$data[pearprice]?/p
?
}
How would I modify the loop to display 4 items then a row of fruit images
then 4 more items then another row of different fruit images and then
finally finish the loop displaying the final 4 items?
Thanks
Craig

Thanks for the reply Dan,
I don't think that will do what I need. I want to assign my query to a
variable and have the variable inserted into the query statement. See my
script below. If I change the query statement as you show, the rest of the
script will need to be rewritten as $query is used throughout. I'm not able
yet to do that. :(
Any help would be appreciated.
Thanks
Craig
