Hi Jose

How to convert the string column to other data types like "real" while creating calculated column using python?

Thanks

Do the cast in the expression itself. For example:

newColExpr = "real(Trim([myTableCol]))"

That's great! Is it also possible to Update de calculated columns using something similar?
