php - orderby - Order by multiple columns with Doctrine

symfony doctrine order by (2)

In Doctrine 2.x you can't pass multiple order by using doctrine 'orderBy' or 'addOrderBy' as above examples. Because, it automatically adds the 'ASC' at the end of the last column name when you left the second parameter blank, such as in the 'orderBy' function.

For an example ->orderBy('a.fist_name ASC, a.last_name ASC') will output SQL something like this 'ORDER BY first_name ASC, last_name ASC ASC'. So this is SQL syntax error. Simply because default of the orderBy or addOrderBy is 'ASC'.

To add multiple order by's you need to use 'add' function. And it will be like this.

->add('orderBy','first_name ASC, last_name ASC'). This will give you the correctly formatted SQL.

More info on add() function.

Hope this helps. Cheers!

I need to order data by two columns (when the rows have different values for column number 1, order by it; otherwise, order by column number 2)

I'm using a QueryBuilder to create the query.

If I call the orderBy method a second time, it replaces any previously specified orderings.

I can pass two columns as the first parameter:

->orderBy('r.firstColumn, r.secondColumn', 'DESC');

But I cannot pass two ordering directions for the second parameter, so when I execute this query the first column is ordered in an ascending direction and the second one, descending. I would like to use descending for both of them.

Is there a way to do this using QueryBuilder? Do I need to use DQL?

You have to add the order direction right after the column name:

$qb->orderBy('column1 ASC, column2 DESC');

As you have noted, multiple calls to orderBy do not stack, but you can make multiple calls to addOrderBy:

$qb->addOrderBy('column1', 'ASC')
   ->addOrderBy('column2', 'DESC');
