The Power ORM


Querying the database manually is also possible with RedBeanPHP. You can use the SQL query functions provided by RedBeanPHP. To execute a query:

    R::exec'UPDATE page SET title="test" WHERE id = 1' );

To get a multidimensional array:

    R::getAll'SELECT * FROM page' );

The result of such a query will be a multidimensional array:

0] => Array
id] => 1
[title] => frontpage
[text] => hello

Note that you can use parameter bindings as well:

    R::getAll'SELECT * FROM page WHERE title = :title',
':title' => 'home']

To fetch a single row:

    R::getRow'SELECT * FROM page WHERE title LIKE ? LIMIT 1',
'%Jazz%' ]

To fetch a single column:

    R::getCol'SELECT title FROM page' );

And finally, a single cell...

    R::getCell'SELECT title FROM page LIMIT 1' );

To get an associative array with a specified key and value column use:

    R::getAssoc'SELECT id, title FROM page' );

In this case, the keys will be the IDs and the values will be the titles. getAssocRow will return complete rows.

In my examples, I like to use the short array notation.
In PHP < 5.4 you'll have to use the classic array notation:

array( 'key' => 'value' ).

Get the insert ID (4.2+)

To get the ID after an insert in MySQL/MariaDB compatible databases use:

    R::exec'INSERT INTO ... ' );
$id R::getInsertID();

Converting records to beans

You can convert rows to beans using the convertToBeans() function:

    $sql 'SELECT author.* FROM author
        JOIN club WHERE = 7 '
$rows R::getAll$sql );
$authors R::convertToBeans'author'$rows );

As of version 4.3.2 you can also use: R::convertToBean, without the s, for single rows.

There is no need to use mysql_real_escape as long as you use parameter binding.

Besides querying you can also use other database functionality (like transactions) in RedBeanPHP. Learn more about database functions.

How to use queries

Sometimes using a plain query is more efficient than using beans. For instance, consider the following example:

    $books R::findAll'book' );
$books as $book ) {
$book->sharedCategoryList as $cat ) {

Using a plain query this task could be accomplished far more efficiently:

    $books R::getAll'SELECT 
    book.title AS title, AS author, 
    GROUP_CONCAT( AS categories FROM book
    JOIN author ON = book.author_id
    LEFT JOIN book_category ON book_category.book_id =
    LEFT JOIN category ON book_category.category_id = 
$books as $book ) {

One of the biggest mistakes people make with ORM tools is to try to accomplish everything with objects (or beans). They forget SQL is a very powerful tool as well. Use SQL if you are merely interested in generating reports or lists.
