Php 如何在spreep中使用子查询（从其他表）获取行数？

php mysql

Php 如何在spreep中使用子查询（从其他表）获取行数？,php,mysql,propel,Php,Mysql,Propel,我想这样做： SELECT a.*, (SELECT COUNT(*) FROM b where b.col1 = a.col2) as count FROM a 是否可以使用推进标准 $c = new Criteria(); $c->addSelectColumn(aPeer::TABLE_NAME.'.*'); $c->addAsColumn('count', '(SELECT COUNT(*) FROM b WHERE b.col1 = a.col2)'); aPeer::d

我想这样做：

SELECT a.*, (SELECT COUNT(*) FROM b where b.col1 = a.col2) as count FROM a
是否可以使用推进标准

$c = new Criteria();
$c->addSelectColumn(aPeer::TABLE_NAME.'.*');
$c->addAsColumn('count', '(SELECT COUNT(*) FROM b WHERE b.col1 = a.col2)');
aPeer::doSelect($c);
