Re: [PHP-DB] Is there any I can do to copy data from a mysql database to access database?
There is a "tool" in Access that can connect an access database to any type of database [via ODBC]. It can be used as a table, so you can make all query rigth the way as other table. i'm sorry but i don't remember the "tool" name.

Glad to help. I was actually interested in your post because of forking versus threading.

Re: [PHP-DB] Forking and database connections
Hey Dwight, After getting your first e-mail, I started adding the PEAR::DB persistent connection code. Unfortunately, it yielded the same results that I was getting before. At a hunch, I created a second proof-of-concept script that uses the mysql_* functions in the PHP base. For each of these, I set the $new_link parameter in the mysql_connect() function to "true". As it turns out, the primary $db link that was originally created in the parent process *is* destroyed when the first child process closes -- this makes sense, however. If I re-create that thread after spawning all the child processes, though, it works beautifully! So it looks like this is a bug with PEAR::DB in handling persistent connections across forked processes. I'll go ahead and file it with the PEAR::DB folk and include the two scripts in the bug request. Again, thanks for your help! It was really beneficial to have a second set of eyes and a sounding board for getting through this problem. In case anyone wants the second proof-of-concept script: Thanks!

RE: [PHP-DB] Forking and database connections
Good point. Anything (children or parent) sharing the connection will get
it closed on them. I was looking up persistent connections, then I thought
you could just address the way you used the pcntl_* functions.
I use mysql_* directly (where mysql_connect "Opens or reuses a connection to
a MySQL server."), so you may need to look into PEAR::DB for persistent
connections.
Where in your code does it say you are using persistent connections? I
haven't had the need to use them yet.
For instance mysql_pconnect (the persistent counterpart) says "Second, the
connection to the SQL server will not be closed when the execution of the
script ends."
If you are using the PEAR::DB persistent connection as documented, then I'd
open a bug report. Again, I haven't used them.

Dwight

[PHP-DB] PDO prepared statements sometimes returns empty resultset
Hi,
I'm trying to get some data form a MySQL db using PDO and prepared
statement, but I noticed that sometimes it fetches an empty result set,
but sometimes does what it's supposed to do - returns the whole result set.
The environment is WinXP SP2 Home, Apache 2.2.4, PHP 5.2.1 and MySQL 5.0.27.
Here is some code:
$db = new PDO(
'mysql:host=localhost;dbname=name_of_db',
'user_name',
'password',
array (
PDO::ATTR_PERSISTENT => true
)
);
$db->query('SET CHARACTER SET utf8');
$stmt = $db->prepare("CALL sp_get_all_currencies(:lang_id)");
$stmt->bindValue(':lang_id', $currenctLanguageId, PDO::PARAM_INT);
$stmt->execute();
$currencies = $stmt->fetchAll();
So here, $currencies sometimes is an empty array, and after a refresh of
the browser it populates.
I also noticed that it works ok with $db->query(), but query doesn't
have that fancy param binding (I think).
Is there some caching or something... Is this a bug in PHP or I'm not
getting the picture right?
Regards,
Emil Ivanov

Re: [PHP-DB] Forking and database connections
Hey Dwight,
Thanks for the replies! When the first child thread closes, all of the DB
connections seem to close. That is, the $db->execute() statements will fail
in the child threads after the first child thread closes. It's almost as
though separate connections are not being made, but they are instead sharing
the same connection. This would make sense if persistent connection pooling
was enabled, but I assumed there to be a "garbage collection" mechanism in
place to avoid prematurely closing a persistent connection if multiple
resources are using it.
Again, thanks for the help! Any other ideas on what might be wrong, or
should I open a bug against it?
Thanks!
Chris

Actually I suppose you need to loop with foreach to wait on all children

they grab a new $db connection in the first for loop
"} else if ( $pid ) {" I bet a child closes the one you create after the for

In your foreach when you wait for each child, can you $db->execute($stmt,

I think after the wait is when the child closes the connection (since I
suppose you are reusing the same connection), so it is already closed.
