我从NativeQuery生成一个SQL,结果是sql:
SELECT COUNT(id)AS tot,created_at FROM property WHERE created_at '20120501000000'与'20120521235959'BROUP BY之间的比较 YEAR(created_at),月(created_at),日(created_at);
这是我的ResultSetMapping:
$rsm = new \Doctrine\ORM\Query\ResultSetMapping;
$rsm->addEntityResult('Entity\Property', 'p');
$rsm->addFieldResult('p','count(id)','tot'); // <-- this don't work
$rsm->addFieldResult('p','created_at','created_at');
直接在mysql上运行上述查询的结果是可以的:
tot created_at
11 2012-05-02 11:23:25
11 2012-05-08 14:56:40
152 2012-05-16 14:43:46
5 2012-05-17 16:26:31
29 2012-05-18 14:55:33
但结果数组的别名不存在!!
问题是:
我如何为 count(id)正确设置ResultSetMapping?
答案 0 :(得分:0)
我会尝试:
$rsm->addFieldResult('p', 'tot', 'tot');
将您的列重命名为并添加COUNT(id) AS tot
。如果删除tot
别名,则可以使用原始代码:
$rsm->addFieldResult('p', 'COUNT(id)', 'tot');
