Natively Connect to Oracle SCM Data in PHP

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

• Url: The URL of the account that you want to connect to. Typically, this will be the URL of your Oracle Cloud service. For example, https://servername.fa.us2.oraclecloud.com.
• User: The username of your Oracle Cloud service account.
• Password: The password of your Oracle Cloud service account.

Establish a Connection

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

$conn = odbc_connect("CData ODBC OracleSCM 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.

$conn = odbc_pconnect("CData ODBC OracleSCM Source","user","password");
...
odbc_close($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 Carriers WHERE ActiveFlag = ?");

Execute Queries

Execute prepared statements with .

$conn = odbc_connect("CData ODBC OracleSCM Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Carriers WHERE ActiveFlag = ?");
$success = odbc_execute($query, array('false'));
 

Execute nonparameterized queries with .

$conn = odbc_connect("CData ODBC OracleSCM Source","user","password");
$query = odbc_exec($conn, "SELECT CarrierId, CarrierName FROM Carriers WHERE ActiveFlag = 'false'");
 

Process Results

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

$conn = odbc_connect("CData ODBC Oracle SCM data Source","user","password");
$query = odbc_exec($conn, "SELECT CarrierId, CarrierName FROM Carriers WHERE ActiveFlag = 'false'");
while($row = odbc_fetch_array($query)){
 echo $row["CarrierId"] . "\n";
}

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

$conn = odbc_connect("CData ODBC Oracle SCM data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Carriers WHERE ActiveFlag = ?");
$success = odbc_execute($query, array('false'));
if($success)
 odbc_result_all($query);
