Hello Mike,
Thank you very much for answering.
I have to admit that I don't understand.
session.query(Mytable).add_column(cast(Mytable.colB,Float) /
cast(Mytable.colC,Float)).all()
gives bad results while
session.execute("""SELECT * , CAST(Mytable.colB AS FLOAT) /
CAST(Mytable.colC AS FLOAT)AS CALCUL FROM Mytable""")
gives correct results.
Thanks
Dominique
