I have a requirement to fetch data from some tables through a query and write them into a csv file.
UTL_FILE concept is taking long time (more than 30 mins) to generate the csv as millions of records present in the database.
Please suggest which is the best method to achieve the goal.

I am using oracle 11g database.

Just use a simple sql query (no pl/sql needed) and set COLSEP

see https://docs.oracle.com/cd/E11882_01/server.112/e16604/ch_twelve040.htm#SQPUG069
