可用的查询设置如下：
| 参数 | 描述 | 举例 |
|---|---|---|
| conditions | Search conditions for the find operation. Is used to extract only those records that fulfill a specified criterion. By default Phalcon\Mvc\Model assumes the first parameter are the conditions. | “conditions” => “name LIKE ‘steve%’” |
| columns | Return specific columns instead of the full columns in the model. When using this option an incomplete object is returned | “columns” => “id, name” |
| bind | Bind is used together with options, by replacing placeholders and escaping values thus increasing security | “bind” => array(“status” => “A”, “type” => “some-time”) |
| bindTypes | When binding parameters, you can use this parameter to define additional casting to the bound parameters increasing even more the security | “bindTypes” => array(Column::BIND_TYPE_STR, Column::BIND_TYPE_INT) |
| order | Is used to sort the resultset. Use one or more fields separated by commas. | “order” => “name DESC, status” |
| limit | Limit the results of the query to results to certain range | “limit” => 10 / “limit” => array(“number” => 10, “offset” => 5) |
| group | Allows to collect data across multiple records and group the results by one or more columns | “group” => “name, status” |
| for_update | With this option, Phalcon\Mvc\Model reads the latest available data, setting exclusive locks on each row it reads | “for_update” => true |
| shared_lock | With this option, Phalcon\Mvc\Model reads the latest available data, setting shared locks on each row it reads | “shared_lock” => true |
| cache | Cache the resultset, reducing the continuous access to the relational system | “cache” => array(“lifetime” => 3600, “key” => “my-find-key”) |
| hydration | Sets the hydration strategy to represent each returned record in the result | “hydration” => Resultset::HYDRATE_OBJECTS |
If you prefer, there is also available a way to create queries in an object-oriented way, instead of using an array of parameters:
