Natively Connect to EnterpriseDB Data in PHP

Drop the CData ODBC Driver for EnterpriseDB into your LAMP or WAMP stack to build EnterpriseDB-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to EnterpriseDB 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.

The following connection properties are required in order to connect to data.

• Server: The host name or IP of the server hosting the EnterpriseDB database.
• Port: The port of the server hosting the EnterpriseDB database.

You can also optionally set the following:

• Database: The default database to connect to when connecting to the EnterpriseDB Server. If this is not set, the user's default database will be used.

Connect Using Standard Authentication

To authenticate using standard authentication, set the following:

• User: The user which will be used to authenticate with the EnterpriseDB server.
• Password: The password which will be used to authenticate with the EnterpriseDB server.

Connect Using SSL Authentication

You can leverage SSL authentication to connect to EnterpriseDB data via a secure session. Configure the following connection properties to connect to data:

• SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
• SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
• SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
• SSLClientCertType: The certificate type of the client store.
• SSLServerCert: The certificate to be accepted from the server.

Establish a Connection

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

$conn = odbc_connect("CData ODBC EnterpriseDB 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.

$conn = odbc_pconnect("CData ODBC EnterpriseDB Source","user","password");
...
odbc_close($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 Orders WHERE ShipCountry = ?");

Execute Queries

Execute prepared statements with .

$conn = odbc_connect("CData ODBC EnterpriseDB Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Orders WHERE ShipCountry = ?");
$success = odbc_execute($query, array('USA'));
 

Execute nonparameterized queries with .

$conn = odbc_connect("CData ODBC EnterpriseDB Source","user","password");
$query = odbc_exec($conn, "SELECT ShipName, ShipCity FROM Orders WHERE ShipCountry = 'USA'");
 

Process Results

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

$conn = odbc_connect("CData ODBC EnterpriseDB data Source","user","password");
$query = odbc_exec($conn, "SELECT ShipName, ShipCity FROM Orders WHERE ShipCountry = 'USA'");
while($row = odbc_fetch_array($query)){
 echo $row["ShipName"] . "\n";
}

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

$conn = odbc_connect("CData ODBC EnterpriseDB data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Orders WHERE ShipCountry = ?");
$success = odbc_execute($query, array('USA'));
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 EnterpriseDB-specific adaptations of the PHP community documentation for all ODBC functions.
