Hi..
I can build a table and add columns to this using one of this two methods:
method 1:
Load *,
calculated_field1;
load *,
calculated_field2;
load *
resident atable;
method 2:
load *
resident atable;
join
load key_field,
calculated_field1
resident atable;
join
load key_field,
calculated_field2
resident atable;
Is there any advantage using any of this over the other?? maybe speed or memory usage??
