Hello all
Just a quick query. What is the abbreviation to calculate the area of
a polygon in hectares in creating a temporary calculation column?
Square miles is calculated fine and I can derive the calculation from
that but would prefer to do the area calculation in one quick
process.

Any help greatly appreciated as always.

Hendrik,

I guess you are looking for this keyword: "Hectare"

Select CartesianArea(OBJ, "Hectare") "Area_Ha"
From MYTABLE
