public initConnection(ConnectionInterface $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

ConnectionInterface $con
array $settings An array of settings.

setCharset()

in PdoAdapter at line 130
public setCharset(ConnectionInterface $con, string $charset)

Sets the character encoding using SQL standard SET NAMES statement.

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

Parameters

ConnectionInterface $con
string $charset The $string charset encoding.

Return Value

string The string in a case that can be ignored.

in PdoAdapter at line 166
public string ignoreCaseInOrderBy(string $in)

(Interbase for example) does not use the same SQL in ORDER BY
and other clauses.

Parameters

string $in The string whose case to ignore.

Return Value

string The string in a case that can be ignored.

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

Binds values in a prepared statement.

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

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

Parameters

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

in PdoAdapter at line 532
