-/**
- * TDbConnection represents a connection to a database.
- *
- * This is a port of {@link http://www.yiiframework.com Yii} {@link http://www.yiiframework.com/ CDbConnection}
- *
- * TDbConnection works together with {@link TDbCommand}, {@link TDbDataReader}
- * and {@link TDbTransaction} to provide data access to various DBMS
- * in a common set of APIs. They are a thin wrapper of the {@link http://www.php.net/manual/en/ref.pdo.php PDO}
- * PHP extension.
- *
- * To establish a connection, set {@link setActive active} to true after
- * specifying {@link connectionString}, {@link username} and {@link password}.
- *
- * The following example shows how to create a TDbConnection instance and establish
- * the actual connection:
- * <pre>
- * $connection=new TDbConnection($dsn,$username,$password);
- * $connection->active=true;
- * </pre>
- *
- * After the DB connection is established, one can execute an SQL statement like the following:
- * <pre>
- * $command=$connection->createCommand($sqlStatement);
- * $command->execute();   // a non-query SQL statement execution
- * // or execute an SQL query and fetch the result set
- * $reader=$command->query();
- *
- * // each $row is an array representing a row of data
- * foreach($reader as $row) ...
- * </pre>
- *
- * One can do prepared SQL execution and bind parameters to the prepared SQL:
- * <pre>
- * $command=$connection->createCommand($sqlStatement);
- * $command->bindParam($name1,$value1);
- * $command->bindParam($name2,$value2);
- * $command->execute();
- * </pre>
- *
- * To use transaction, do like the following:
- * <pre>
- * $transaction=$connection->beginTransaction();
- * try
- * {
- *    $connection->createCommand($sql1)->execute();
- *    $connection->createCommand($sql2)->execute();
- *    //.... other SQL executions
- *    $transaction->commit();
- * }
- * catch(Exception $e)
- * {
- *    $transaction->rollBack();
- * }
- * </pre>
- *
- * TDbConnection also provides a set of methods to support setting and querying
- * of certain DBMS attributes, such as {@link getNullConversion nullConversion}.
