I have a table with a column abc carrying the unix timestamp (eg. 13898161481435) and I want to run a between dates select.
It would be not efficient to do a
where TO_CHAR(TO_TIMESTAMP(abc / 1000), 'DD/MM/YYYY') > '14/01/2014 00:00:00' and ..;
which would convert every record.
Rather do something like
where abc > ('14/01/2014 00:00:00' tobigint()) and abc < ...
But I cant find any reference, though for the reverse case.
