Natively Connect to Quaderno Data in PHP

Drop the CData ODBC Driver for Quaderno into your LAMP or WAMP stack to build Quaderno-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to Quaderno data, execute queries, and output the results.

Configure a DSN

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Start by setting the Profile connection property to the location of the Quaderno Profile on disk (e.g. C:\profiles\Quaderno.apip). Next, set the ProfileSettings connection property to the connection string for Quaderno (see below).

Quaderno API Profile Settings

Find your API Key in your Quaderno account under Developers > API Keys > Private Key. Your AccountName is the subdomain of your Quaderno URL.

Establish a Connection

Open the connection to Quaderno by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.

$conn = odbc_connect("CData ODBC API Source","user","password");

Connections opened with odbc_connect are closed when the script ends. Connections opened with the odbc_pconnect method are still open after the script ends. This enables other scripts to share that connection when they connect with the same credentials. By sharing connections among your scripts, you can save system resources, and queries execute faster.

$conn = odbc_pconnect("CData ODBC API Source","user","password");
...
odbc_close($conn); //persistent connection must be closed explicitly

Create Prepared Statements

Create prepared statements and parameterized queries with the odbc_prepare function.

$query = odbc_prepare($conn, "SELECT * FROM Coupons WHERE Code = ?");

Execute Queries

Execute prepared statements with odbc_execute.

$conn = odbc_connect("CData ODBC API Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Coupons WHERE Code = ?");
$success = odbc_execute($query, array('SUMMER2024'));
  

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC API Source","user","password");
$query = odbc_exec($conn, "SELECT Id, Name FROM Coupons WHERE Code = 'SUMMER2024'");
  

Process Results

Access a row in the result set as an array with the odbc_fetch_array function.

$conn = odbc_connect("CData ODBC Quaderno data Source","user","password");
$query = odbc_exec($conn, "SELECT Id, Name FROM Coupons WHERE Code = 'SUMMER2024'");
while($row = odbc_fetch_array($query)){
 echo $row["Id"] . "\n";
}

Display the result set in an HTML table with the odbc_result_all function.

$conn = odbc_connect("CData ODBC Quaderno data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Coupons WHERE Code = ?");
$success = odbc_execute($query, array('SUMMER2024'));
if($success)
  odbc_result_all($query);
