* Doctrine_Query
|
|
|
24 |
* A Doctrine_Query object represents a DQL query. It is used to query databases for
|
|
|
25 |
* data in an object-oriented fashion. A DQL query understands relations and inheritance
|
|
|
26 |
* and is dbms independant.
|
|
|

* @subpackage Query

* @license http://www.opensource.org/licenses/lgpl-license.php LGPL
|

|

* @link www.doctrine-project.org

* @since 1.0
|
|
|

* @version $Revision: 7674 $
|
|
|
34 |
* @author Konsta Vesterinen <kvesteri@cc.hut.fi>
|
|
|
35 |
* @todo Proposal: This class does far too much. It should have only 1 task: Collecting
|
|
|
36 |
* the DQL query parts and the query parameters (the query state and caching options/methods
|
|
|
37 |
* can remain here, too).
|
|
|
38 |
* The actual SQL construction could be done by a separate object (Doctrine_Query_SqlBuilder?)
|
|
|
39 |
* whose task it is to convert DQL into SQL.
|
|
|
40 |
* Furthermore the SqlBuilder? can then use other objects (Doctrine_Query_Tokenizer?),
|
|
|
41 |
* (Doctrine_Query_Parser(s)?) to accomplish his work. Doctrine_Query does not need
|
|
|
42 |
* to know the tokenizer/parsers. There could be extending
|
|
|
43 |
* implementations of SqlBuilder? that cover the specific SQL dialects.
|
|
|
44 |
* This would release Doctrine_Connection and the Doctrine_Connection_xxx classes
|
|
|
45 |
* from this tedious task.
|
|
|
46 |
* This would also largely reduce the currently huge interface of Doctrine_Query(_Abstract)
|
|
|
47 |
* and better hide all these transformation internals from the public Query API.
|
|
|
48 |
*
|
|
|
49 |
* @internal The lifecycle of a Query object is the following:
|
|
|
50 |
* After construction the query object is empty. Through using the fluent
|
|
|
51 |
* query interface the user fills the query object with DQL parts and query parameters.
|
|
|
52 |
* These get collected in {@link $_dqlParts} and {@link $_params}, respectively.
|
|
|
53 |
* When the query is executed the first time, or when {@link getSqlQuery()}
|
|
|
54 |
* is called the first time, the collected DQL parts get parsed and the resulting
|
|
|
55 |
* connection-driver specific SQL is generated. The generated SQL parts are
|
|
|
56 |
* stored in {@link $_sqlParts} and the final resulting SQL query is stored in
|
|
|
57 |
* {@link $_sql}.
