Set options for connection or statement resources
bool db2_set_option ( resource $resource, array $options, int $type )
Sets options for a statement resource or a connection resource. You cannot set options for result set resources.
Parameters:
resource
A valid statement resource as returned from db2_prepare() or a valid connection resource as returned from db2_connect() or db2_pconnect().
options
An associative array containing valid statement or connection options. This parameter can be used to change autocommit values, cursor types (scrollable or forward), and to specify the case of the column names (lower, upper, or natural) that will appear in a result set.
type
An integer value that specifies the type of resource that was passed into the function. The type of resource and this value must correspond.
Passing 1 as the value specifies that a connection resource has been passed into the function.
Passing any integer not equal to 1 as the value specifies that a statement resource has been passed into the function.
Returns:
Returns TRUE on success or FALSE on failure.
Examples:
Setting one parameter with a connection resource
<?php
/* Database Connection Parameters */
$database = 'SAMPLE';
$hostname = 'localhost';
$port = 50000;
$protocol = 'TCPIP';
$username = 'db2inst1';
$password = 'ibmdb2';
/* Connection String */
$conn_string = "DRIVER={IBM DB2 ODBC DRIVER};DATABASE=$database;";
$conn_string .= "HOSTNAME=$hostname;PORT=$port;PROTOCOL=$protocol;";
$conn_string .= "UID=$username;PWD=$password;";
/* Obtain Connection Resource */
$conn = db2_connect($conn_string, '', '');
/* Create the associative options array with valid key-value pairs */
$options = array('autocommit' => DB2_AUTOCOMMIT_ON);
/* Call the function using the correct resource, options array, and type values */
$result = db2_set_option($conn, $options, 1);
/* Check if all options could be set correctly */
if($result)
{
echo 'Options Set Successfully';
}
else
{
echo 'Could Not Set Options';
}
?>
The above example will output:
Options Set Successfully
Setting multiple parameters with a connection resource
