Natively Connect to Avaza Data in PHP

Drop the CData ODBC Driver for Avaza into your LAMP or WAMP stack to build Avaza-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to Avaza 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 Avaza Profile on disk (e.g. C:\profiles\Avaza.apip). Next, set the ProfileSettings connection property to the connection string for Avaza (see below).

Avaza API Profile Settings

Register an OAuth application in Avaza under Settings > Manage Developer Apps > OAuth 2 Apps > Add OAuth App to obtain your client ID and secret credentials.

Establish a Connection

Open the connection to Avaza by calling the or methods. To close connections, use or .

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

Connections opened with are closed when the script ends. Connections opened with the 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 function.

$query = odbc_prepare($conn, "SELECT * FROM Account WHERE DefaultCurrencyCode = ?");

Execute Queries

Execute prepared statements with .

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

Execute nonparameterized queries with .

$conn = odbc_connect("CData ODBC API Source","user","password");
$query = odbc_exec($conn, "SELECT Id, CompanyName FROM Account WHERE DefaultCurrencyCode = 'USD'");
 

Process Results

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

$conn = odbc_connect("CData ODBC Avaza data Source","user","password");
$query = odbc_exec($conn, "SELECT Id, CompanyName FROM Account WHERE DefaultCurrencyCode = 'USD'");
while($row = odbc_fetch_array($query)){
 echo $row["Id"] . "\n";
}

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

$conn = odbc_connect("CData ODBC Avaza data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Account WHERE DefaultCurrencyCode = ?");
$success = odbc_execute($query, array('USD'));
if($success)
 odbc_result_all($query);

You will find complete information on the driver's supported SQL in the help documentation. The code examples above are Avaza-specific adaptations of the PHP community documentation for all ODBC functions.
