Typo3 Extbase如何获取具有关系= x的所有对象？

Question

I want to use Extbase on my Project. But I don't get this query to Work:

SELECT
    tx_domain_model_A.*,
    tx_domain_model_B.*
FROM
    tx_domain_model_A LEFT JOIN tx_domain_model_B ON (tx_domain_model_B.uid IN (tx_domain_model_A.b_I_D))
WHERE
    tx_domain_model_B.von >= ?
ORDER BY tx_domain_model_B.von

The result should like this:

A.uid   A.b_I_D B.uid   B.von
1       5,8,3   5       abc
1       5,8,3   8       def
1       5,8,3   3       ghi
2       1,2     1       123
2       1,2     2       456
3       1       1       123

I use:

$query = $this->createQuery();
$query->matching($query->greaterThanOrEqual('bID.von',date('U')));

But then, all Child Objects are empty. I think this comes from: http://fossies.org/dox/typo3_src-6.2.9/Typo3DbQueryParser_8php_source.html

function addUnionStatement ...
...

    // TODO check if there is another solution for this
    785         $sql['keywords']['distinct'] = 'DISTINCT';

So I do it with a $query->statement(...) but this don't work too.

I want to get all Objects from Table A which have A.B_I_D.von bigger than today. Table B (= A.B_I_D ) is an n:1 relation ( A=n:B=1 ). How can I get an Object from A more than one time? And can use it in Fluid?

I use Typo3 6.2

ok first of all extbase queries will always give you full objects as a result. that is why you need to use statement to achive your goal. The second trick to get the result as you want is that you need to set to receive result as a array. It is needed beacause extbase is trying to map your statement to object of model related with repository

you can change the type of return data using setReturnRawQueryResult : you can read more about it here http://docs.typo3.org/typo3cms/ExtbaseFluidBook/6-Persistence/3-implement-individual-database-queries.html
