DateDiff MySQL function with Doctrine

[eluser]Unknown[/eluser]
hi Everyone,

I have used the Doctrine 2 library in my application, however, I am unable to use the DateDiff function in any of my SQL statements.

I have made a more detailed explanation here:

Please advise if anybody has ever done it successfully.

Thank you so much.
