// create default adapter
$adapter = Table::getAdapter('default'); // get  adapter from $configure[adapters][default]

or $adapter = Table::getAdapter(); // get the first adapter from $configure[adapters]

// create write adapter
$adapter = Table::getAdapter('write'); // get  adapter from $configure[adapters][write]

or $adapter = Table::getWriteAdapter() // get adapter from $configure[adapters][*write_adapter_name*]

Execute

$num = $adapter->execute('select * from *table* limit 20');
var_dump($num);

Query

$result = $adapter->query('select * from *table* limit 20');
print_r($result->fetch());

Prepare

$stmt = $adapter->prepare('select * from *table* where id = :id and status = :status limit 20');
$stmt->bindValue(':status', 1);
$stmt->bindValue(':id', 10);
$stmt->execute();
print_r($stmt->fetch());

Use SQL builder, _(*8)
