The CData ODBC driver for ServiceNow enables you to create PHP applications with connectivity to ServiceNow data. Leverage the native support for ODBC in PHP.
Drop the CData ODBC Driver for ServiceNow into your LAMP or WAMP stack to build ServiceNow-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to ServiceNow 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.
ServiceNow uses the OAuth 2.0 authentication standard. To authenticate using OAuth, you will need to register an OAuth app with ServiceNow to obtain the OAuthClientId and OAuthClientSecret connection properties. In addition to the OAuth values, you will need to specify the Instance, Username, and Password connection properties.
See the "Getting Started" chapter in the help documentation for a guide on connecting to ServiceNow.
Establish a Connection
Open the connection to ServiceNow by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.
$conn = odbc_connect("CData ODBC ServiceNow 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.
$conn = odbc_pconnect("CData ODBC ServiceNow Source","user","password");
...
odbc_close($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 incident WHERE category = ?");
Execute Queries
Execute prepared statements with odbc_execute.
$conn = odbc_connect("CData ODBC ServiceNow Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM incident WHERE category = ?");
$success = odbc_execute($query, array('request'));
Execute nonparameterized queries with odbc_exec.
$conn = odbc_connect("CData ODBC ServiceNow Source","user","password");
$query = odbc_exec($conn, "SELECT sys_id, priority FROM incident");
Process Results
Access a row in the result set as an array with the odbc_fetch_array function.
$conn = odbc_connect("CData ODBC ServiceNow data Source","user","password");
$query = odbc_exec($conn, "SELECT sys_id, priority FROM incident");
while($row = odbc_fetch_array($query)){
echo $row["sys_id"] . "\n";
}
Display the result set in an HTML table with the odbc_result_all function.
$conn = odbc_connect("CData ODBC ServiceNow data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM incident WHERE category = ?");
$success = odbc_execute($query, array('request'));
if($success)
odbc_result_all($query);
