hi,
With a JMP query builder, and with the post query script, I create a new column with something like this:
dt << NewColumn("BMI", Numeric, Continuous, Formula(:weight/:height^2));
but, my problem is: when I update from database the jmp file, I create a new column "BMI 2".
and with an another update: a new column BMI 3.
I would like to have only one column BMI at each update from database.
is it possible?
best regards
