setConnectionParameter

Syntax

From ADOdb Version 5.21.0

void setConnectionParameter(
    string $parameterName,
    mixed $parameterValue
    )

Description

The function setConnectionParameter() permits the setting of parameters before a database connection is established. This allows the specified parameters to be passed to the connect statement.

If used in a portable environment, parameters set in this manner should be predicated on the database provider, as unexpected results may occur if applied to the wrong database.

Database Specific Values

$parameterName must be one of the predefined constants defined in PHP documentation for the mysqli_options() function.

Firebird

$parameterName must be one of the 3 following values:

role

buffers

Oracle

$parameterName may be one of the following

session_mode

Sets the Oracle Session Mode. The default value is OCI_DEFAULT. Other values are:

$db->setConnectionParameter('session_mode',OCI_SYSDBA);
$db->connect($database,$user,$password);
