2) Automatically dump the results in to DUMP_YYYYMMDDHH24MISS.txt
3) Result set is tar gziped
4) upload to SFTP URL with provided username and password.

Answer 1

This is really 4 questions and should probably asked as such. To answer in the current format though:
1) Schedule a Task Automatically - Crontab
In the terminal, type crontab -e.
If you want something every Sunday at 1am, add the following line:
0 1 * * * 0 /path/to/script/script.sh
This will execute the script every Sunday.
2) Setting the output of the command
I'm only familiar with oracle. The format is probably similar. In order to get the filename as you want it, you'd use the date function as follows. (This is how I would do it in with Oracle):
d=$(date +%Y%M%D%H%M)
var=$(sqlplus -s / as blahblahblah
select * from stuff;
exit
EOF
)
file_name=DUMP_${d}MISS.txt
echo "${var}" >> ${file_name}
Note that your date command is probably different, if you do a man page on date it will tell you which parameters you'd need to get the date formatted as you like.
3) Taring the output
tar -xvf ${file_name}
4) Send over SFTP
You'd have to authenticate the sftp, that is beyond the scope of what anyone can answer without more details. Once you have the machines setup to authenticate, you would do:
sftp username#server<<EOF
put ${file_name}
EOF
