How to concatenate string in select clause of a google sheet query?

How can I concatenate a string in a select clause of google sheet query function ?

ex: =QUERY(DATAS!B:F; "SELECT B,C,D,'=image('&E&')',F WHERE upper(F) "&J4&" upper('"&N4&"') LIMIT 50";1)

Here I want to get E column as =image(E) in the sheet.

Anyone with an idea ?

Thanks :d
