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);
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.
$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.

| 메소드 | 설명 | |
|---|---|---|
| __call ( $method, $args ) : mixed | Dynamic find method using parts of method name as search criteria. | |
| __construct ( $table, $connection ) | Creates a new generic table gateway for a given table or view name and a database connection. | |
| count ( $criteria = null, $parameters = [] ) : integer | Find the number of records. | |
| deleteAll ( $criteria, $parameters = [] ) : integer | Delete records from the table with condition given by $where and binding values specified by $parameter argument. | |
| deleteAllByPks ( $keys ) | Alias for deleteByPk() | |
| deleteByPk ( $keys ) : integer | Delete records by primary key. Usage: | |
| find ( $criteria, $parameters = [] ) : array | Find one single record that matches the criteria. | |
| findAll ( $criteria = null, $parameters = [] ) : TDbDataReader | Accepts same parameters as find(), but returns TDbDataReader instead. | |
| findAllByPks ( $keys ) : TDbDataReader | Similar to findByPk(), but returns TDbDataReader instead. | |
| findAllBySql ( $sql, $parameters = [] ) : TDbDataReader | Execute arbituary sql command with binding parameters. | |
| findByPk ( $keys ) : array | Find one record using only the primary key or composite primary keys. Usage: | |
| findBySql ( $sql, $parameters = [] ) : array | Execute arbituary sql command with binding parameters. | |
| getDbConnection ( ) : TDbConnection | ||
| getLastInsertId ( ) : mixed | ||
| getTableInfo ( ) | ||
| getTableName ( ) | ||
| insert ( $data ) : mixed | Inserts a new record into the table. Each array key must correspond to a column name in the table unless a null value is permitted. | |
| onCreateCommand ( $sender, $param ) | Raised when a command is prepared and parameter binding is completed. | |
| onExecuteCommand ( $sender, $param ) | Raised when a command is executed and the result from the database was returned. | |
| update ( $data, $criteria, $parameters = [] ) : integer | Updates the table with new name-value pair $data. Each array key must correspond to a column name in the table. The update condition is specified by the $where argument and additional binding values can be specified using the $parameter argument. |
