Natively Connect to Azure Analysis Services Data in PHP
The CData ODBC driver for Azure Analysis Services enables you to create PHP applications with connectivity to Azure Analysis Services data. Leverage the native support for ODBC in PHP.
Drop the CData ODBC Driver for Azure Analysis Services into your LAMP or WAMP stack to build Azure Analysis Services-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to Azure Analysis Services 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.
To connect to Azure Analysis Services, set the Url property to a valid server, for instance, asazure://southcentralus.asazure.windows.net/server, in addition to authenticating. Optionally, set Database to distinguish which Azure database on the server to connect to.
Azure Analysis Services uses the OAuth authentication standard. OAuth requires the authenticating user to interact with Azure Analysis Services using the browser. You can connect without setting any connection properties for your user credentials. See the Help documentation for more information.
Establish a Connection
Open the connection to Azure Analysis Services by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.
$conn = odbc_connect("CData ODBC AAS 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.
$conn = odbc_pconnect("CData ODBC AAS Source","user","password");
...
odbc_close($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 Customer WHERE Country = ?");
Execute Queries
Execute prepared statements with odbc_execute.
$conn = odbc_connect("CData ODBC AAS Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Customer WHERE Country = ?");
$success = odbc_execute($query, array('Australia'));
Execute nonparameterized queries with odbc_exec.
$conn = odbc_connect("CData ODBC AAS Source","user","password");
$query = odbc_exec($conn, "SELECT Country, Education FROM Customer WHERE Country = 'Australia'");
Process Results
Access a row in the result set as an array with the odbc_fetch_array function.
$conn = odbc_connect("CData ODBC Azure Analysis Services data Source","user","password");
$query = odbc_exec($conn, "SELECT Country, Education FROM Customer WHERE Country = 'Australia'");
while($row = odbc_fetch_array($query)){
echo $row["Country"] . "\n";
}
Display the result set in an HTML table with the odbc_result_all function.
$conn = odbc_connect("CData ODBC Azure Analysis Services data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Customer WHERE Country = ?");
$success = odbc_execute($query, array('Australia'));
if($success)
odbc_result_all($query);
More Example Queries
You will find complete information on the driver's supported SQL in the help documentation. The code examples above are Azure Analysis Services-specific adaptations of the PHP community documentation for all ODBC functions.
