I guess the spaces at the beginning of the lines were the problem(?)

In any case, a couple of observations:
- The clause "rownum < 1" is always false. Oracle's pseudo-column rownum has an integer value of 1 or higher. Looks like in your case the shell script does not throw any error, but the update statement doesn't update anything either.

- The backticks from "sqlplus" to the "EOF" are not necessary if do not want to assign the output of the sqlplus command to a shell variable.

- If your file: sv_tn.list has a large number of rows, then connecting to sqlplus and updating the database for each row may be too expensive and inefficient.
If you only want to update all rows with the "tn" values in the sv table, then you may want to go through the sv_tn.list file, collect all "tn" values into a comma-delimited list and then issue a single update like so:

Code:
update sv set old_ts=sysdate, status=7 where status=1 where tn in $tn_list

where tn_list has the form:
Code:
('123','456','789')

and can be created like so:

Code:
$
$ cat sv_tn.list
45879
8928712
9901
$
$ tn_list=`awk '{printf("%c%s%c,", 39,$0,39)}' sv_tn.list | sed -e 's/^\(.*\),$/\(\1\)/'`
$
$ echo $tn_list
('45879','8928712','9901')
$
$
