Greetings!
Looking at the ascii_io module, I can't seem to find a way for loading up multiple BATs where one column of the input is specified as the head value. Is there such an option, or is it always a VOID loadup?
In particular, I have a << lng >> column as the primary key. So, using my current understanding, I would need to load up a set of dummy/temp BATs, and then using these load the data to the real BATs.
Ascii_io was designed for loading wide-tables. Each column of the table is loaded into a bat[void,val]. The void heads link the columns together. So if one of the columns of this table is your primary key (lng) that is not a problem. Probably you could do without the primary (unless referenced in one of the other columns).
