I'm trying the below script (script is in PHP, database is ODBC connection to db2 for as400) but I'm having issues due to the db2_last_insert_id being an unknown function.
I need to use the odbc setup for this script, and all other odbc functions work, but I can't find a function in ODBC that replicates the db2_last_insert_id functionality
What is the best way for me to grab the id of the inserted row within the script itself?
if($DB2connPROD){
$insertTable = "INSERT INTO testing_insert_php (name) VALUES ('Temp Name')";
$stmt = odbc_exec($DB2connPROD, $insertTable);
$ret = db2_last_insert_id($DB2connPROD);
if($ret) {
echo "Last Insert ID is : " . $ret . "\n";
} else {
echo "No Last insert ID.\n";
}
odbc_close($DB2connPROD);
}
Use VALUES identity_val_local() as your query. It will return a resultset with a single row and column.
You can't mix and match DB access libraries. If you are using ODBC, then you have to use ODBC for everything associated with that connection. You can't use ODBC to open a connection, and then DB2_ to operate on that connection.
In fact, both IBM_DB2 and PDO_IBM require a DB2 client, and the only one that works with DB2 for i is found in the DB2 Connect product. Unless the web server is running on IBM i itself.

I have searched on many different sites and cannot find an answer that specifically answers this question:
I have WAMP Server installed, which installed phpmyadmin as well as MySQL. I can easily connect to the database through php/pdo by using localhost as my hostname.
But my problem is I am trying to connect to a database that I have exported from phpmyadmin as "mydatabase.sql". So now lets say I placed this file on my pc at "C:\Users\Username\Desktop\MyFolder\mydatabase.sql". How would I connect to this database (if this is possible)?
The reason is that I cannot install WAMP Server on all the pcs that would use this program. so would like to be able to connect to the database without having to install any type of servers, etc...
My php at the moment is:
<?php
$dsn='mysql:C:\Users\Username\Desktop\MyFolder\mydatabase.sql';
$username='username';
$password='pass';
try
{
$dbh = new PDO("$dsn",$username,$password);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo 'Connected to Database<br/>';
$sql = "SELECT * FROM users";
foreach ($dbh->query($sql) as $row)
{
echo $row["ID"] ." - ". $row["Name"] ."<br/>";
}
$dbh = null;
}
catch(PDOException $e)
{
echo $e->getMessage();
}
?>
Also, if this is possible, would username and password be necessary to connect to an "off server database"?
If I try:
$dsn='sqlite:C:\Users\Optique\Desktop\optique.sql';
I get:
"Connected to Database
SQLSTATE[HY000]: General error: 26 file is encrypted or is not a database"
But I think that is because SQLite uses a different database format than MySQL (stand to be corrected). So what I need is something similar to the SQLite driver for MySQL.
Thanks in advance!
You cannot find an answer simply because it doesn't exist: it's impossible to connect to an SQL dump through PDO, and it makes no sense anyway: a dump is not a database but simply a collection of INSERT queries. Unlike sqlite, for mysql you need a server to connect with.
To be able to connect, you should import that dump into mysql database first and then connect to that database with PDO.
I have a script that clones tables on to uniquely named MySQL databases from a master sql dump file . Each account has their own database, but the table structure is the same for all accounts. My solution was to dump the master database table and then through PHP shell_exec, run the MySQL controller cmd (mysql) to populate the newly created database with default tables.
At Issue: The process works but only when I hard code the accounts unique database name in the master sql dump file.
However, "USE acct_dbID" line inside the master sql file needs to be dynamically set at runtime.
Here is the code:
include('.dbase_credentials'); //constants for connection object
//using PHP built in connection class mysqli
$mysqli = new mysqli(DB_HOST,DB_UNAME,DB_UPWORD,DB_NAME);
if ($mysqli->connect_errno){
echo "Failed to open database connection: ".$mysqli->connect_error;
exit();
}
$dbID=$varNum; //variable, number ID generated earlier in the account setup process
//create database, doesnt return a resultset, no need for object var here
if ($mysqli->query("CREATE DATABASE acct_".$dbID) === TRUE){
//if dbase was created, clone the tables
$res = shell_exec('mysql -u dbaseUser --password=`cat /path/to/pass` -e "source /path/to/master_tables.sql" acct_'.$dbID);
//provide some UI feedback, shell_exec returns null on failure
if ($res!=null){
echo "The tables were cloned!";
}else{
echo "The cloning process failed!";
}
}else{
echo "no database created.";
}
So again, master_tables.sql needs variable data passed it at runtime so the "USE acct_dbID" can be specific to each new account.
Any thoughts are appreciated.

knittl had the right direction for what I need to do. See the comment conversation above. Thanks knittl.
Here is the new code block using multi_query and file_get_contents.
if ($mysqli->query("CREATE DATABASE acct_".$dbID) === TRUE){
$acct="acct_".$dbID;
$query = "USE ".$acct.";";
$query .= file_get_contents('/path/to/master_table.sql');
$result=$mysqli->multi_query($query);
}
Now account can be variable and multi_query will run each query statement in the string. I probably lose some efficiency but gain the ability to clone tables for each new account. The only additional edit made was to the master_table.sql. I removed all the comments that the dump process adds.
Thanks,

I am using the php_oci8 extension to connect to my database in Oracle 10g. Although, I am able to connect to my database using the scott/tiger account , I am not able to run any query against that database. I am using Windows XP-32 bit and Oracle 10g.
I am using WampServer 2.1 for executing my PHP scripts
This is my php script used to execute an update query on a table:
<?php
$conn = oci_connect('scott','tiger','');
if(!$conn)
echo "Not connected";
else
{
$query = " UPDATE demo SET amount=4500 where id=1";
$stmt = oci_parse($conn, $query);
oci_execute($stmt, OCI_DEFAULT);
echo "amount updated";
}
?>
On execution of this script, I get the message amount updated but the updated value doesn't reflect in the database table. Can anyone tell me why is this happening? Is there any solution to this?
Thanks in advance
I'm using HostMonster as my web host and I'm trying connect to a database I created using MySQL inside of HostMonster. In order to call that database in my website do I need to use PHP? Or is there a way to create a javascript OnClick function that can call the database. I'm not using ASP.Net so it's not quite as simple as I would like it. Just curious if the best solution is PHP, if so I guess I should go learn it.
what are you planning to do with the database, other than just 'calling it'? You will need some language like PHP to connect to the DB to retrieve, insert, update or delete data in the DB.
here is a code for connection MySQL from PHP using MYSQLI extension
<?php
$dba_host='localhost';
$dba_name='root';
$dba_pass='';
$dba_db='sn';
$con=mysqli_connect($dba_host,$dba_name,$dba_pass,$dba_db) or die('Connection Refused !');
$stmt=mysqli_prepare($con,"SELECT UID FROM Main");
mysqli_stmt_execute($stmt);
mysqli_stmt_bind_result($stmt, $value);
while(mysqli_stmt_fetch($stmt))
$result[] = $value;
mysqli_stmt_close($stmt);
mysqli_close($con);
?>
Your javascript onClick function is running on the client side (in the browser) and the database is running on the server-side. You will need a server-side language to get the information from the database and send it to the browser.
You do not HAVE to use PHP to connect to a MYSQL database. Also, you can't connect to your database using only client-side javascript (ie. an onClick() function). You need to use a server side language, PHP is one choice.
To connect to a MYSQL database on hostmonster using PHP you will need to know your credentials that use to log into phpMyAdmin from your cpanel. Once you have made the connection you can then select the MYSQL database that you created. Once the database is selected you can query it using the "mysql_query" function in PHP. The following code does all of that and stores the results of the MYSQL query in a PHP variable called $result.
<?php
$con = mysql_connect("www.yourdomain.com","phpMyAdmin_username","phpMyAdmin_password");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("mysql_database_name", $con);
$query = "SELECT * FROM TableName"
$result = mysql_query($query);
?>
Now you've got the results of the query inside the PHP variable $result and you can use it anyway you like.
If you put this in your 'public_html' folder and named it 'index.php' or 'index.html' this would automatically be run when someone went to www.yourdomain.com.

Can I use PHP with Oledb connection?
As far as I know database connection as provided by PHP extension are all odbc.
You can use ActiveX Data Objects (Microsoft's OLEDB ActiveX layer) in PHP-Win without any third party extension as such:
$conn = new COM("ADODB.Connection") or die("Cannot start ADO");
// Microsoft Access connection string.
$conn->Open("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\inetpub\wwwroot\php\mydb.mdb");
// SQL statement to build recordset.
$rs = $conn->Execute("SELECT myfield FROM mytable");
echo "<p>Below is a list of values in the MYDB.MDB database, MYABLE table, MYFIELD field.</p>";
// Display all the values in the records set
while (!$rs->EOF) {
$fv = $rs->Fields("myfield");
echo "Value: ".$fv->value."<br>\n";
$rs->MoveNext();
}
$rs->Close();
Look at the ADOdb Library for PHP extension. I've never used it, but it seems to be compatible with OLEDB providers.
maybe......
found an article on it.
found the PHP extension for it.
Don't know anything about it. Best of luck.
