Today I wrote a preparation script for the oracle sqlloader.
Some of the records I needed to load were expected to be already in the table.
The script should take a file and generate delete statements for each records primary key.
I thought Perls inplace edit feature would be a quick way to generate the list and I came up with the following solution.
cp insert.data delete.sql
perl -F';' -ani -e 'print "delete from atable where afield = $F[0]\n";
+ END {print "quit\n"}' delete.sql
sqlplus ... @delete.sql
sqlldr loadme.ctl
Everything seemed to work except the "quit" line I added to quit sqlplus. It was printed to STDOUT instead delete.sql
Why is it not added as the last line of delete.sql?
I fixed it with
echo quit >> delete.sql
The second question I have is a general one and OT. Is this a reasonable way to update an Oracle 8 Database table?
