[PHP-DB] Database Abstraction Layer?
Hello everybody, What do you think is the best method to abstract php code from a specific database?. Make PHP code 100% database independent?.. Waitin' for your comments. Muhammed Mamedov

[PHP-DB] PHP - MsSQL - DB error connect failed
It is not directly PHP but it is Db with PHP/Linux
Linux 2.4.19-4GB
Apache: httpd-2.0.48
php-4.3.4
freetds-0.61.2
I have php pages to connect to MsSQL-2000 server
$conn = mssql_connect($server, $user, $pass)
or die ;
or (PEAR:Db)
$dsn = mssql://$user:[EMAIL PROTECTED]/$dbname;
if (DB::isError($db)) {die ($db-getMessage()); }
PHP-pages with these instructions worked this morning.
Later and still now: DB error connect failed : impossible to connect now.
I suspect the MsSQL server to be overloaded.
Other users (Windows) are connecting via piped names
Myself (on Linux) connect via IP-address
If I reboot in Windows-2000 (Dual-boot system): no problem to access Db (piped
name).
If I make a test (on Linux) with tsql (FreeTDS): connection OK
Only problem is to try connecting through Apache/PHP on Linux via IP-Address
I had once problem making a DHCP enquiry on a Windows server from a Linux Host
and I had to increase the TimeOut thus I wondered if I do not have the same
problem now.
I checked thus /www/conf/php.ini
I uncommented the lines:
mssql.connect_timeout = 10
mssql.timeout = 60
and tried higher numbers but without success. Apache/PHP don't seem to repeat
the request till success.
If anybody knows of a way to awake or shake MsSQL (apart from blowing it). Of
course, the obvious is to install MySQL bur I am not the master here.

Thanks Chris... that worked great. No worries. Guess I need to spend a _lot_ more time reading the manual. It also helps alot just lurking on the list (this and/or PHP general).

There are a couple of products out there that I am about to start testing, starting first with: - SQL Relay http://sqlrelay.sourceforge.net/ This product uses its on C interfaces to interact with DBs and different programming languages. It addresses a bunch of items in the PHP DB calls. Connection pooling and load balancing. - Propel http://propel.phpdb.org/ Extensive templates create the SQL definition files you need to setup your database and the classes you need to work with your data model in your PHP scripts. The classes for your object model are generated from a simple XML schema and any customizations are written in plain PHP. This will effectively that add SQL and DB dependence out of your mix.

RE: [PHP-DB] Database Abstraction Layer?
Oh ya, one more thing, I am going to integrate SQL Relay with the PHP abstraction layer: http://sourceforge.net/projects/sqlalphp to give the functions a more PHP feel to them. Plus, I will be able to retain DB specific calls if I want with this layer. I have used this layer with a great deal of success in the past. But it was never the DB calls that got me, it was the actually SQL. So I am building a swappable SQL library. The Propel solution would effectively negate me having to do that. - Paul -Original Message- From: Muhammed Mamedov [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 21, 2004 3:41 AM To: phpdb Subject: Re: [PHP-DB] Database Abstraction Layer?

[PHP-DB] MSSQL stability problem
I have a site that makes heavy use of a local SQL Server database. Every 6-12 hours the site continuously reports not being able to connect to the database.

RE: [PHP-DB] Database Abstraction Layer?
PEAR is great from what I hear. The issue you are going to run into with DB independence is not the function calls which could be handled with something as simple as sqlalphp. It is the SQL calls themselves. The two options I have found is a SQL library with unembeded SQL or the Propel solution. Either way adds a significant time to coding and product release initially. - Paul -Original Message- From: Muhammed Mamedov [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 21, 2004 10:07 AM To: [EMAIL PROTECTED]; phpdb Subject: Re: [PHP-DB] Database Abstraction Layer?

If you really want true portability, you may want to try Metabase or PEAR::MDB which is a conversion of Metabase to follow PEAR coding style, although not all Metabase drivers have been ported to MDB. Metabase was written with the specific goal to be truly database independent, so you do not have to change anything in your application to make it work with different applications. This means that not only the database access is portable but also the schema installation and maintenance. Metabase lets you define your database schema in a simple XML format and then it takes care of creating the tables, fields, indexes and sequences in any of the supported databases. If you want to change your schema, just edit the XML definition and Metabase is capable of figuring what changed and alter the installed schema according to the database you are using, without affecting any data that was added since the database was installed for the first time or after it was updated for the last time. If you have an application working with an existing database, Metabase provides experimental support for migrating the installed schema to the database independent XML definition format. http://www.phpclasses.org/metabase -- Regards, Manuel Lemos Free ready to use OOP components written in PHP http://www.phpclasses.org/ -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Re: PHP - MsSQL - DB error connect failed - mssql_pconnect?
mssql_pconnect() may add to problem of too many connections. The reason is because the persistent connection is associated with the Apache child process and not the script. This is significant because you are not guaranteed to be served by the same child everytime the script is invoked. Thus, over an extendend period of operation, the result will be a persistently open connection for each active Apache child process. -- bob t On Wed, 21 Jan 2004, Alain [iso-8859-15] Barthélemy wrote: Le mercredi 21 janvier 2004, 13:55:26 ou environ Alain Barthélemy [EMAIL PROTECTED] a écrit: Still another question in my (desperate?) trials to connect to a MsSQL-2000 Server from a Linux host.

[PHP-DB] using query_strings in sql
I'm a cold fusion refugee and am having incredible problems with something
that I think is relatively easy -- so I must be missing something basic.
I would like to pull info from a query string and use it inside a database
call.
I can pull the query string into a general variable:
?php echo $section; ?
now I would like to use it in a SQL statement, or in
if/else clauses to modifiy results from queries.
examples below:
USE query_string in SQL :
?php
function whatever(){
$username = ;
...
// setting the default variables
if(!isset($category)){$category=Something;}
if(!isset($section)){$section=SomethingElse;}
[EMAIL PROTECTED]($hostname,$username,$password);
mysql_select_db($database);
$selection = mysql_query(
SELECT *
FROM classes
WHERE
classCategory = '$category'
ORDER BY $reorder $order
)
...
?
The PHP SQL call below work nicely:
while ($row = mysql_fetch_array($selection)){
echo $row[sectionName];
}
now I would like to do an if/else to modifiy it:
while ($row = mysql_fetch_array($selection)){
if (section == $sectionName){
echo b . $row[sectionName] . /b;
}else{
echo $row[sectionName];
}
Nothing is working. I must be missing something basic over here.

Re: [PHP-DB] using query_strings in sql
I may be misunderstanding you, but your first statement about pulling from a
query string is throwing me.
?php echo $section; ? will only display the value of $section on the screen.
You will need to build a form to get a value into $section.
form action=soemthing.php
input type=text name=section
/form
something.php:
?php echo This is what was submitted in the form: .$section; ?
Now you can do your query:
$selection = mysql_query(SELECT *
FROM classes
WHERE
classCategory = '$section'
)
you'll notice I pulled the other variables out since you had not defined them
yet, like your ordering variables. Otherwise the SQL would end with ORDER
which will cause an error..

that I think is relatively easy -- so I must be missing
something basic.
I would like to pull info from a query string and use it
inside a database
call.
I can pull the query string into a general variable:
?php echo $section; ?
now I would like to use it in a SQL statement, or in
if/else clauses to modifiy results from queries.
examples below:
USE query_string in SQL :
?php
function whatever(){
$username = ;
...
// setting the default variables
if(!isset($category)){$category=Something;}
if(!isset($section)){$section=SomethingElse;}
[EMAIL PROTECTED]($hostname,$username,$password);
mysql_select_db($database);
$selection = mysql_query(
SELECT *
FROM classes
WHERE
classCategory = '$category'
ORDER BY $reorder $order
)
...
?
The PHP SQL call below work nicely:
while ($row = mysql_fetch_array($selection)){
echo $row[sectionName];
}
now I would like to do an if/else to modifiy it:
while ($row = mysql_fetch_array($selection)){
if (section == $sectionName){
echo b . $row[sectionName] . /b;
}else{
echo $row[sectionName];
}
Nothing is working. I must be missing something basic over here.

Re: [PHP-DB] using query_strings in sql
Looking at that. You are combining html and php without distinguishing
between the two. I am assuming you are in php mode because html wouldn't
give you errors. try this:
echo a href='somefile.php?order=;
if ($order == ASC){
echo DESC;
}else{
echo ASC;
}

I have a table displaying data. The column headers are links that allow
the

basic version is:
a href=somefile.php?order=ASCTitle/a
a closer to reality version is (or would be if it worked)
a href=somefile.php?order=

}else{
echo ASC;
}
(Actually that would be a switch/case :-) )
The sql call is
$selection = mysql_query(

And since there is no query string when someone lands on the page there
needs to be a default value set:
// setting the default variables
if(!isset($order)){$order=ASC;}
Unfortunately its not working :(

I may be misunderstanding you, but your first statement about
pulling from a
query string is throwing me.
?php echo $section; ? will only display the value of $section
on the screen.
You will need to build a form to get a value into $section.
form action=soemthing.php
input type=text name=section
/form
something.php:
?php echo This is what was submitted in the form: .$section; ?
Now you can do your query:
$selection = mysql_query(SELECT *
FROM classes
WHERE
classCategory = '$section'
)
you'll notice I pulled the other variables out since you had not
defined them
yet, like your ordering variables. Otherwise the SQL would end
with ORDER
which will cause an error..

[PHP-DB] Selecting last record only
Hi gang this is probably ridicously simple, but I'm new at this SQL stuff, so am a bit stumped. It's pretty simple: how do I get only the last record from a single table? Trying to convert my file-based website into DB-based, but can't quite figure out how to do this simple task. Table name is history, and only have 3 fields: histID, date, entry I need it to pick the last record without knowing the date of it. Got picking specific records down good, but be damned if I can figure this one out...

Re: [PHP-DB] Selecting last record only
Reverse the order and limit the result to 1.
For example, change:
SELECT date, item from some_table
To:
Select date, item from some_table ORDER BY date DESC LIMIT 1
to get the latest dated item.

Re: [PHP-DB] using query_strings in sql
Here goes:
1) That should work fine. Be sure and enclose the SQL in double quotes or the
variable will not get translated into its value.
2) That's fine too, nothing wrong there.
3) this is wrong, but it looks like you just ommited the SQL statement. Be
sure and use the or die statement as it will forward any SQL errors to the
screen.
$selection = mysql_query(SELECT *
FROM whatever
WHERE someField = '$queryString_variable') or die(mysql_error());
while ($row = mysql_fetch_array($selection)){
if (query_variable is X){
echo $row[classID];
}else{
echo b . $row[classID] . /b;
}
There isn't anything obviously wrong with the code, it should be doing
something, at least printing out the html heading information. Try looking at
the page source for errors as well. Change the query to include the or
die(mysql_error()); code because the script might be dying with a SQL error
and you just aren't seeing it printed out.

Le mercredi 21 janvier 2004, 13:07:24 ou environ Robert Twitty [EMAIL PROTECTED] a écrit: mssql_pconnect() may add to problem of too many connections. The reason is because the persistent connection is associated with the Apache child process and not the script. This is significant because you are not guaranteed to be served by the same child everytime the script is invoked. Thus, over an extendend period of operation, the result will be a persistently open connection for each active Apache child process. -- bob Thank you for this explanation. That is well what I supposed. I guess the other MsSQL clients (Windows) are doing something like a permanent connection. I can't force my way through with my Linux/PHP host. I secretly hoped that mssql_pconnect would allow me to have a materially permanent connection and prevent anybody to take my place. Well! It was just a hope. I hoped too to launch plenty of permanent connections and prevent the others to connect in order to force the administrator to think how to solve the problem if there was a way to solve it. I must say I am doing a development work of connection of a Linux server with Apache/PHP to a MsSQL-2000 server in an environment dominated by Windows/IIS/ASP. IIS/ASP are for me a pain in the ass (I respect the others with another opinion) but I have to understand very well the inner working of the MsSQL server without having access to the configuration of it (personnaly I don't think the administrator understands it which is another problem). Thus any hint is welcome. Thank you again.

Hi Alain
ODBTP is a protocol that provides remote access to WIn32-based ODBC
drivers. More details are available at http://odbtp.sourceforge.net. I
created it because PHP's mssql ext did not adequately support SQL Server
7.0 and 2000. The main problem with this ext is that on UNIX it was built
with FreeTDS, a reengineered and sometimes faulty version of the TDS
protocol. On Windows it was built with the obsolete and unsupported
DB-Library, which does not support ntext or varchar(255) data types.
ODBTP provides the best access to MSSQL because it uses the ODBC driver
for SQL Server by Microsoft. It is faster than the FreeTDS version, and
is equal in speed to the DB-Library version.
Version 1.0 is publically available at SourceForge. Version 1.1 will be
released soon. This version should interest you because it provides
support for all of the mssql_* functions.
Let me know if you want to try it.

Of course, I have not heard of ODBTP yet but I am not a specialist of Windows.
Hi Alain
Would you like to try a better solution for connecting to MSSQL? It does
not use FreeTDS, and will not require you to change your code. It's called
ODBTP.

If I reboot in Windows-2000 (Dual-boot system): no problem to access Db (piped

If I make a test (on Linux) with tsql (FreeTDS): connection OK
Only problem is to try connecting through Apache/PHP on Linux via IP-Address
I had once problem making a DHCP enquiry on a Windows server from a Linux Host

problem now.
I checked thus /www/conf/php.ini
I uncommented the lines:
mssql.connect_timeout = 10
mssql.timeout = 60
and tried higher numbers but without success. Apache/PHP don't seem to repeat
the request till success.
If anybody knows of a way to awake or shake MsSQL (apart from blowing it). Of
course, the obvious is to install MySQL bur I am not the master here.

RE: [PHP-DB] using query_strings in sql
oops. I guess I was too loose with my words ---
something does happen, just not what I want! :-)
The page displays. The sql works, the or die doesn't return anything.
I'm able to change the sql by changing the default values.
WHAT DOESN'T HAPPEN is that the query_string values DO NOT trump the default
variables.
so query_string = ?class=Xsection=Yorder=ASC
I can't input these variables : $class,$section,$order into the SQL
statement
SELECT *
FROM classes
WHERE section=$section
ORDER BY $class $order

Re: [PHP-DB] using query_strings in sql
You may have register Globals turned off in php.ini.
Try adding:
extract($_GET)
in the code before the function gets called. That's not a very secure method,
but it will prove whether or not that's the problem.

Subject: Re: [PHP-DB] using query_strings in sql
Here goes:
1) That should work fine. Be sure and enclose the SQL in double
quotes or the
variable will not get translated into its value.
2) That's fine too, nothing wrong there.
3) this is wrong, but it looks like you just ommited the SQL
statement. Be
sure and use the or die statement as it will forward any SQL
errors to the
screen.
$selection = mysql_query(SELECT *
FROM whatever
WHERE someField = '$queryString_variable') or die(mysql_error());
while ($row = mysql_fetch_array($selection)){
if (query_variable is X){
echo $row[classID];
}else{
echo b . $row[classID] . /b;
}
There isn't anything obviously wrong with the code, it should be doing
something, at least printing out the html heading information.
Try looking at
the page source for errors as well. Change the query to include the or
die(mysql_error()); code because the script might be dying with
a SQL error
and you just aren't seeing it printed out.

RE: [PHP-DB] using query_strings in sql
it works
thx Micah (and Matt)
I have no knowledge (YET) of how to prevent sql injection attacks with php.
For this project I'm not too concerned as it is in a password protected area
and only 2 or 3 people have access to it.
I hope this works with the rest of the issues...

[PHP-DB] CREATE TABLE problem

not successful. the database name, user,pw,and local host are all correct. i have no
idea what do do, and i have 2 more tables besides this one i wanted to create but this
was kind of my template for it and i cant even get it to work. im still really bad

Re: [PHP-DB] CREATE TABLE problem
mysql_db_query ($dbname,$query,$link) or die(myself_error());
will help you more than your if/then statement.. change that, and check out
the error message.

[PHP-DB] A site mapped in a database / xml
Hi, I have an question on how to create a completely database / xml driven site i.e. the page names, links, the site map etc are held in the database. I think I have solved most problems but what I would really like to do is limit the number of pages I need. Can I manipulate the server such that if I have links to a pages; a href=red_hats.phpred_hats.php/a and a href=yellow_hats.phpyellow_hats.php/a can both these pages and others link to a different page that dynamically constructs whilst the links aren't altered. Maybe is there some way that a default php page is called that reads the link of the page called etc. I would be most grateful for your input on this. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP-DB] Truncated fields
I'm having a problem with retrieving field data from SQL SERVER 2000 and am not sure where the problem lies. I have a variable length field (from 100 - 1 characters). When I retrieve the field using a select statement, then into a PHP variable such as $text=$r['body_text'], then the field seems to be truncated after a good bit of it has been returned (at least 1000 characters). I am using PHP 4.3.4 and FREETDS 0.62 on a Red Hat 9.0 system to access SQL Server. The question is, is there a returned field size maximum defaulting or defined in SQL Server, PHP, or FREETDS and/or has anyone else had this problem? Thanks.
