Load field containg numbers as matrix with numbers as fieldnames
I don't think that's necessary.
Note that the Generic load will create a lot of tables, but all will have a table name like 'tmp.245', 'tmp.123' etc., i.e. the Tablename we used for the Generic load (here: tmp) and then the field values for your ID.
Please note further, that there is a where clause in your TableList load:
WHERE WildMatch(TableName($(i)), 'tmp.*');
here we match table names that have a preceding 'tmp.', i.e. that were created in our Generic Load.
So preloading other tables should not be a problem, if their names don't start with 'tmp.'
Re: Load field containg numbers as matrix with numbers as fieldnames
But this taes like years to finish. I am loading a file with per minute data. it takes like 3 seconds for every hour to load -> 7.3 hours for a year to load! This is huge! Is there no other way for loading it?
