Update the table using values from a csv file
i want to run update query for oracle which is in up.sql taking values from a.csv.
I have implemented shell script to do it.
Code:
 
extn="perl"
ls -1 | while read file
do
echo "$file,$extn" > a.csv
done

up.sql contains
Code:
update file_list set filename=$1 where extn=$2;

The code to update is as below
Code:
 
while read line
file=`cut -d "," -f 1`
extn=`cut -d "," -f 2`
do
sqlplus <<END
username/password@connectstring
@update.sql $file $extn
commit;
END
done< a.csv

Since there are a large no files..i dont want to run the sqlplus command that much of time...
Is there any way to use a.csv to update the table...I tried sqlldr but it is working only for inser not for update.
