[PHP-DB] Re: if else question
I've always done it like this: $count = mysql_num_rows( $result ); if( $count == 0 ) then doomething(); But there may be a better way.. In yours it appears you are testing for anything in mysql_num_rows($result) and a value of 0 in mysql_num_rows($ret). I may be misundertanding you. Do you mean to test for the value of both to be 0? If that's the case, I was under the impression that it would have to be if( $foo == 0 AND $bar == 0 ) then doSomething(); but I could be wrong..

[PHP-DB] Re: Multiple selects?
Are you talking about something that will display a list of products like this page: http://survivalherbs.com:8080/order/index.php?command=viewCategory&category= Herbal+Remedies These are all gathered from the database with one SELECT statement then put together in the table with a while loop.. Is that what you're talking about? If so, I have the code for it. I wrote the cart that is hosted on that page and can post some code from it if you would like..

[PHP-DB] Re: Stroing info in a variable
This is what I have.. I think it's along the same lines as what you are
asking.. If not, just ignore my drunken ramblings.. It isn't with oci stuff
but if it's similar to what you need then you should be able to convert it
over..
$result = $database->query( "SELECT * FROM contacts WHERE cartId='$cartId'
ORDER BY lastName, firstName" );
while( $data = $database->fetchRow( $result ) )
{
echo( "$data->lastName, $data->firstNamemailto:$data->emailAddress\">$data->emailAddress\n" );
}
Now from what I understand of your question, you could remove the while so
you had $data = $database->fetchRow( $result ); then use if() tests to
compare $data->varName values.. If you wanted to compare values in different
rows, then I guess you could leave the while loop and just replace the
echo() with your if() tests..
Sorry if I missed the point of your question.. I hope this helps though..

[PHP-DB] Re: difficult sql statement. Help needed
The above post may be unclear.. What he did was used if() statements to
compare whatever and generate the query differently based on what he found..
$lotsOdata = $database->result( "SELECT * FROM someTable" );
$count = mysql_num_rows( $lotsOdata );
while( $count > 0 ) {
if( $lotsOdata[city] != "philly" ) {
$sql = $database->query( "INSERT INTO otherTable $thisData" );
}
else if( $this[thing] = $that ) {
$sql = $database->query( "UPDATE someVar SET thisValue =
$thatData" );
}
}
I hope this makes sense, and it's all correctly written.. I'm pretty new at
this myself so I may have some bugs..

Maybe change mysql_fetch_array($ret) to mysql_fetch_row($ret)? Not sure but
I've used that before to do what appears to be similar while loops..
Wouldn't the data still get retrieved in array form with that? If I'm wrong,

Hey, if the databases contain the same data, why don't you just have them use one database. Just set up MySQL with a user on the internet server that the intranet system uses to connect to it with.. Do it over SSL and it would be secure then. Wouldn't that be somewhat simpler and less time consuming? I mean if they are meant to contain the same data anyway...

[PHP-DB] Re: mysql_num_rows
I ran into the same problem on a script yesterday.. It turns out that one of
the vars in my mysql_connect() command wasn't assigned.. It gave me no
indication of this so I hadn't thought to look there.. I just happened to be
reading back through the whole page to see what I could find and noticed
that I hadn't set the var at the top..
Something else that I noticed in your code is that there doesn't seem to be
a mysql_select_db() call.. Unless that is somewhere else in the code and
just not shown here, you'll need it I believe..
Just a couple thoughts,

[PHP-DB] Re: Delete from mysql table is there a way to....
I'm not sure how to change DELETE statements in this fashion, but is there a
way maybe to run an OPTIMIZE TABLE query every so often in your PHP script..
I don't imagine you'd want it running too often since it locks the table you
run it on, but maybe on the reload of $PHP_SELF or something.. It can take a
while to run on tables with lots of data, so it may not be the best option
anyway.. Just a thought though.. Ooh, maybe a PHP script run from a cron job
every couple hours or something even??

[PHP-DB] Re: Delete from mysql table is there a way to....
Maybe if you ran the delete query, then the optimize table query immed
after, it wouldn't take such a long time.. I would imagine if you had quite
large tables though, it could still take some time.. And if users are
connecting over the internet, you don't want too may delays..
If the user doesn't need any specific feedback about the delete command, you
could do a low priority delete.. That's sketchy at best though from what I
could gather in the manual and around. It just queues the query until the
database is done with everything but it sounds like it might release the
user/client to go on with what they're doing..
You might also check into truncate.. The mysql manual talks about it
briefly.. I guess it's an Oracle thing that mysql supports.. It sounds like
it would keep things clean but sounds slow possibly..

RE: [PHP-DB] Multiple table select, but still returning row if no record exists in second table?
The query should look similar to this: SELECT table1.col as [column_a], table2.col as [column_b] FROM table1 LEFT JOIN (or LEFT OUTER JOIN) table2 ON table2.some_key_col = table1.some_key_col ... for all required keysWHERE -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
