Hi,
Without using sqlite, I can sort the table test ('sort' is from
coreutils, sort on the 1st column then the 2nd column), then I use awk
to parse the sorted file to get what I need. Should this approach be
faster than the sqlite query (in terms of runtime, not in term of
programming time)?
On
you can use:
select col1, col2 from test where col1 in (select col1 from test group by col1
having count(*)<=2);
