spool /u01/app/oracle/export/mysheet.csv
select * from mytab'
spool off

參考解法
方法 1:
I have used this package from oracle‑developer.net in a production database and it has worked flawlessly. It works on Oracle 8i onwards.
方法 2:
Use the results from your SQL and then use the PL/SQL package UTL_FILE to open and write to a file, separating your results with commas in a variable first.
As an example:
vline would contain the results from your SELECT with each column separated by a comma as in SELECT col1 ||','|| col2 ||',|| ... INTO vline ...
vfile is the name of your file.
UTL_FILE.PUT_LINE(vfile, vline));
Search Oracle docs for more info on the UTL_FILE package.
