-/**
- * TActiveRecordHasOne models the object relationship that a record (the source object)
- * property is an instance of foreign record object having a foreign key
- * related to the source object. The HAS_ONE relation is very similar to the
- * HAS_MANY relationship (in fact, it is equivalent in the entities relationship point of view).
- *
- * The difference of HAS_ONE from HAS_MANY is that the foreign object is singular.
- * That is, HAS_MANY will return a collection of records while HAS_ONE returns the
- * corresponding record.
- *
- * Consider the <b>entity</b> relationship between a Car and a Engine.
- * <code>
- * +-----+ +--------+
- * | Car | 1 <----- 1 | Engine |
- * +-----+ +--------+
- * </code>
- * Where each engine belongs to only one car, that is, the Engine entity has
- * a foreign key to the Car's primary key. We may model
- * Engine-Car <b>object</b> relationship as active record as follows.
- * <code>
- * class CarRecord extends TActiveRecord
- * {
- * const TABLE='car';
- * public $car_id; //primary key
- * public $colour;
- *
- * public $engine; //engine foreign object
- *
- * public static $RELATIONS=array
- * (
- * 'engine' => array(self::HAS_ONE, 'EngineRecord')
- * );
- *
- * public static function finder($className=__CLASS__)
- * {
- * return parent::finder($className);
- * }
- * }
- * class EngineRecord extends TActiveRecord
- * {
- * const TABLE='engine';
- * public $engine_id;
- * public $capacity;
- * public $car_id; //foreign key to cars
- *
- * public static function finder($className=__CLASS__)
- * {
- * return parent::finder($className);
- * }
- * }
- * </code>
- * The static <tt>$RELATIONS</tt> property of CarRecord defines that the
- * property <tt>$engine</tt> that will reference an <tt>EngineRecord</tt> instance.
- *
- * The car record with engine property list may be fetched as follows.
- * <code>
- * $cars = CarRecord::finder()->with_engine()->findAll();
- * </code>
- * The method <tt>with_xxx()</tt> (where <tt>xxx</tt> is the relationship property
- * name, in this case, <tt>engine</tt>) fetchs the corresponding EngineRecords using
- * a second query (not by using a join). The <tt>with_xxx()</tt> accepts the same
- * arguments as other finder methods of TActiveRecord, e.g. <tt>with_engine('capacity < ?', 3.8)</tt>.

-/**
- * TTableGateway class provides several find methods to get data from the database
- * and update, insert, and delete methods.
- *
- * Each method maps the input parameters into a SQL call and executes the SQL
- * against a database connection. The TTableGateway is stateless
- * (with respect to the data and data objects), as its role is to push data back and forth.
- *
- * Example usage:
- * <code>
- * //create a connection
- * $dsn = 'pgsql:host=localhost;dbname=test';
- * $conn = new TDbConnection($dsn, 'dbuser','dbpass');
- *
- * //create a table gateway for table/view named 'address'
- * $table = new TTableGateway('address', $conn);
- *
- * //insert a new row, returns last insert id (if applicable)
- * $id = $table->insert(array('name'=>'wei', 'phone'=>'111111'));
- *
- * $record1 = $table->findByPk($id); //find inserted record
- *
- * //finds all records, returns an iterator
- * $records = $table->findAll();
- * print_r($records->readAll());
- *
- * //update the row
- * $table->updateByPk($record1, $id);
- * </code>
- *
- * All methods that may return more than one row of data will return an
- * TDbDataReader iterator.
- *
- * The OnCreateCommand event is raised when a command is prepared and parameter
- * binding is completed. The parameter object is a TDataGatewayEventParameter of which the
- * {@link TDataGatewayEventParameter::getCommand Command} property can be
- * inspected to obtain the sql query to be executed.
- *
- * The OnExecuteCommand event is raised when a command is executed and the result
- * from the database was returned. The parameter object is a
- * TDataGatewayResultEventParameter of which the
- * {@link TDataGatewayEventParameter::getResult Result} property contains
- * the data return from the database. The data returned can be changed
- * by setting the {@link TDataGatewayEventParameter::setResult Result} property.
- *
- * <code>
- * $table->OnCreateCommand[] = 'log_it'; //any valid PHP callback statement
- * $table->OnExecuteCommand[] = array($obj, 'method_name'); // calls 'method_name' on $obj
- *
- * function log_it($sender, $param)
- * {
- * var_dump($param); //TDataGatewayEventParameter object.
- * }

- * TDbCommand class.
- *
- * TDbCommand represents an SQL statement to execute against a database.
- * It is usually created by calling {@link TDbConnection::createCommand}.
- * The SQL statement to be executed may be set via {@link setText Text}.
- *
- * To execute a non-query SQL (such as insert, delete, update), call
- * {@link execute}. To execute an SQL statement that returns result data set
- * (such as select), use {@link query} or its convenient versions {@link queryRow}
- * and {@link queryScalar}.
- *
- * If an SQL statement returns results (such as a SELECT SQL), the results
- * can be accessed via the returned {@link TDbDataReader}.
- *
- * TDbCommand supports SQL statment preparation and parameter binding.
- * Call {@link bindParameter} to bind a PHP variable to a parameter in SQL.
- * Call {@link bindValue} to bind a value to an SQL parameter.
- * When binding a parameter, the SQL statement is automatically prepared.
- * You may also call {@link prepare} to explicitly prepare an SQL statement.

-/**
- * TDbConnection class
- *
- * TDbConnection represents a connection to a database.
- *
- * 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 setConnectionString ConnectionString}, {@link setUsername Username}
- * and {@link setPassword Password}.
- *
- * Since 3.1.2, the connection charset can be set (for MySQL and PostgreSQL databases only)
- * using the {@link setCharset Charset} property. The value of this property is database dependant.
- * e.g. for mysql, you can use 'latin1' for cp1252 West European, 'utf8' for unicode, ...
- *
- * The following example shows how to create a TDbConnection instance and establish
- * the actual connection:
- * <code>
- * $connection=new TDbConnection($dsn,$username,$password);
- * $connection->Active=true;
- * </code>
- *
- * After the DB connection is established, one can execute an SQL statement like the following:
- * <code>
- * $command=$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) ...
- * </code>
- *
- * One can do prepared SQL execution and bind parameters to the prepared SQL:
- * <code>
- * $command=$connection->createCommand($sqlStatement);
- * $command->bindParameter($name1,$value1);
- * $command->bindParameter($name2,$value2);
- * $command->execute();
- * </code>
- *
- * To use transaction, do like the following:
- * <code>
- * $transaction=$connection->beginTransaction();
- * try
- * {
- * $connection->createCommand($sql1)->execute();
- * $connection->createCommand($sql2)->execute();
- * //.... other SQL executions
- * $transaction->commit();
- * }
- * catch(Exception $e)
- * {
- * $transaction->rollBack();
- * }
- * </code>
- *
- * TDbConnection provides a set of methods to support setting and querying
- * of certain DBMS attributes, such as {@link getNullConversion NullConversion}.

- * TDbDataReader class.

- * TDbDataReader represents a forward-only stream of rows from a query result set.

- * To read the current row of data, call {@link read}. The method {@link readAll}
- * returns all the rows in a single array.
- *
- * One can also retrieve the rows of data in TDbDataReader by using foreach:
- * <code>
- * foreach($reader as $row)
- * // $row represents a row of data
- * </code>
- * Since TDbDataReader is a forward-only stream, you can only traverse it once.
- *
- * It is possible to use a specific mode of data fetching by setting
