Using GROUP_CONCAT (MySQl) and WM_CONCAT (Oracle) in Propel

Is there a function in Propel ORM which allows me to use something like a GROUP_CONCAT (or WM_CONCAT ) aggregation on both Oracle10g and MySQL databases?

Well, I know that I can write my own switch, but that's not desirable for me.

Any suggestions?

不,改用withColumn()并将您的Oracle函数放入其中:)
