[Instantobjects-general] SQL - IO

[Dmitry K. <ko...@le...>]

Hi Instantobjecters,

Can anybody answer this question:

What difficulty of SQL query support IO.
Can i execute such query:

SELECT * FROM ANY Contact WHERE Contact.CityName IN
(SELECT CityName FROM City WHERE City.Population > 100 000 )

or can i use JOIN statements in IO query string?
  

Sincerely yours
Dmitry Konnov
