public initConnection(PDO $con, array $settings)

This method is called after a connection was created to run necessary post-initialization queries or code.

If a charset was specified, this will be set before any other queries
are executed.

This base method runs queries specified using the "query" setting.

Parameters

PDO $con A PDO connection instance.
array $settings An array of settings.

This method is invoked from the default initConnection() method and must
be overridden for an RDMBS which does _not_ support this SQL standard.

public bindValues(PDOStatement $stmt, array $params, DatabaseMap $dbMap)

Binds values in a prepared statement.

This method is designed to work with the BasePeer::createSelectSql() method, which creates
both the SELECT SQL statement and populates a passed-in array of parameter
values that should be substituted.

<code>
$db = Propel::getDB($criteria->getDbName());
$sql = BasePeer::createSelectSql($criteria, $params);
$stmt = $con->prepare($sql);
$params = array();
$db->populateStmtValues($stmt, $params, Propel::getDatabaseMap($critera->getDbName()));
$stmt->execute();
</code>

Parameters

PDOStatement $stmt
array $params array('column' => ..., 'table' => ..., 'value' => ...)
DatabaseMap $dbMap

in DBAdapter at line 575
public boolean bindValue(PDOStatement $stmt, string $parameter, mixed $value, ColumnMap $cMap, null|integer $position = null)
