Well, I must admit I don't see how you get any output. You set SQLPLUS to null, the execute ${SQLPLUS}. I would expect you to get something like:-
Code:
scott/tiger@Server: not found
You are limiting the output linesize to 5000. Perhaps your column text has more than that in it. You are retrieving 8 rows with your WHERE clause.
You would be better executing the query to extract one entire record at a time. Set the linesize value to something huge and use the rownum value in your WHERE clause. We can always trim off the excess characters later.
Run this in a loop, increasing the rownum value by 1 each time and change the output file by using the rownum value each time too.
So:-
Query 1 to get total number of rows
Loop for every row
Query 2 to extract 1 very long line into a file into a file based on the row number
End loop
Perhaps coding the SQL query in a file is not the best. If you use a here document, then you can use the row number to vary the output file name and the row selected in one go. You can also avoid having the credentials on the command line for all the world to see with a simple ps -ef | grep sqlplus command whilst you are running.
