在推进ORM v1.6中的UNION查询

I am converting some existing queries into propel ORM. Now i am stuck with converting following similar query in propel.

(SELECT name,address,phone FROM table_1)
UNION
(SELECT name,address,phone FROM table_2)
UNION
(SELECT name,address,phone FROM table_3)

What would be the proper propel implementation for the above query?

This is a rather complex query, you might be better off creating a view from the select and then create a read-only table in your xml schema with the same columns. It has the same beheviour.

<table name="my_table" readOnly="true">
