I'm trying to figure out a way to do a more efficient join on four tables.
The main table is products, with the other tables being common options for
the products. It's pretty well normalized, but am I doing these joins
properly or is there a more efficient way? This looks pretty ugly to me.
Hi,
I used to store SQL code for a transaction

heres an example :

I have an empty field in a mysql database table which needs to have text
inserted when my client answers an email. The code is as follows
$query = 'UPDATE submissions SET answers = "$array[answer]" where id = "$id"
';
// $query = $query . " where id = $id ";
// echo ("The query is: $query\n"
Assume query looks OK when you echo it? You're not seeing a literal "$id",
are you?
Does an id exist for $id? Is it numeric or char?
Check mysql_affected_rows() - what does it return?

First, don't try to force JOIN to do something that is is not designed to
do. Use WHERE to restrict your query.
Try:
SELECT t.team_name,t.flight_id,p.player_fname,p.player_lname
FROM team t
LEFT JOIN player p ON
t.team_id=p.player_team_id
WHERE t.flight_id=p.player_flight_id && p.player_s
Still having problems

What errors are you getting? What do you have inside your db_connection.inc
file? Do you have the path for db_connection.inc inside the require()

It seems that my insert statement doesn't want to cooperate.. I used the
same format as in Julie Meloni's book. I know, sometimes, her code doesn't
always work either.

\"$id\", \"

And the problem is...
You are trying to insert 8 values into 7 fields. You begin your VALUES with
"", but there is not field specified for it.
Don't blame Meloni here until you've proven her wrong.

Next, whenever you have a problem with a query, print mysql_error() as part
of your die() statement. Finally, print your $sql to ensure that it

huh?
You open the connection once for the page and then you CAN make multiple
queries to it from the same page. Why are you trying to create a class to
do this (unless it's simply an intellectual exercise to create a class)?
