There is
APPEND FROM Command
which unlike
IMPORT FROM Command
assumes we know how many fields in CSV and prepared respective table with the same number of fields.
Is there known and free piece of code ( e.g. function ) which behaves like Import for CSV. I.e. max of comas per line in a file will be calculated ,
table with a,b,c,d... max_comas+1 columns created and populated. Seems to be quite common task.
