->keys()
->keys() – Get or set the table keys
Synopsis
array $DB_DataObject->keys ( string $keys ... )
Without any arguments, keys() returns an array of the keys used by the object (the generator builds these and guesses them based on finding things like primary key, unique, or nextval). Calling it with a value, or mulitple values, sets the keys for the current instance of the object.
The default keys are normally stored in the database.ini file described in the Autobuilding section.
Note
This function can not be called statically.
Example
getting the connection
<?php
$person = new DataObjects_Person;
print_r($person->keys());
//
// array(
// 0 => 'id',
// )
//
// now use it to define a on the fly database table...
$d = new DB_DataObject;
$d->tableName('person');
$d->table(array(
'id' => DB_DATAOBJECT_INT,
'name' => DB_DATAOBJECT_STRING,
));
$d->keys('id');
// if you have multiple keys
// $d->keys('id','key2','key2');
$d->id = 12;
$d->find(true);
// should do the same as above..!
