Pick value from file in FOR loop

Question

Hello All,
I was trying to delete records from database day by day and commit. Is it possible to pick the dates from file and then delete the database record for that day. Something like below.
For day IN <File.txt>
LOOP
delete from table where date = '<1st value from File.txt>';
commit;
END LOOP;
I have to do this from unix box, so i can place the file (with list of dates as input) in the path from where i am issuing sqlplus.
Please suggest any other way to delete it day by day is most welcome.
Thanks.

Something like below.You an use EXTERNAL TABLE (Or SQL Loader, if the file cannot be moved to the DB server) to read from a file and it can be used in your DELETE statements just as a normal table.

LOOP is a bad idea.. You could do it in a single statement..
delete from table where date in (select the_date_coumn from the external_table);
And COMMIT inside LOOP is again not a good idea..
