Create New Column with variables

[#1]

Hi all,

I am trying to create a new column with formula, which represented by 2 variables as below:

dt << New Column("myNewColumn", Numeric, Continuous, Formula(:Ceiling( XXColumn / Size) * Size));

where:

XXColumn is one of column name in dt, selected in column dialog

Size = numeric value from column dialog

My attempt resulted a new column with formula with no value as formula create as below:

Ceiling(Column(XXColumn ) / Size) * Size

without actually assign it.

Any idea how I can accomplish this?

[#2 · Accepted solution]

finally the magic happened !!!

here is the code i used..

col = dts << New Column("Binning", Numeric, Continuous);

Eval( Parse( Eval Insert( "col << Set Formula(:Ceiling( ^n_Bin^ / ^BinSize^) * ^BinSize^)<< eval formula" )) );

Thank You MS for the guidance; what is the diff on f_bin and n_bin i used?

As far as I could tell from reading your code f_Bin refers to a column whereas n_Bin is a string, which is the data type that is safest to use here.

Thank you again, MS. I shall take note on this.
