How to show output of dbms_output.put_line used in procedure in sqlplus?

Question

I am trying to execute the procedure from my plsql block using SQLPLUS, unfortunately, I am not able to see the output from "dbms_output.put_line" from procedure just after the execution of SQL script, though the output is visible in the spool file, I wanted to show output in screen once the execution is completed.

For now, I am getting prompt but No output, though when I perform "SET SERVEROUTPUT ON;" in SQL developer it shows output, what shall I do to see the output in sqlplus once execution is completed.

SPOOL OFF;

Answer 1

The output is captured in your spoolfile, temp.lst. It's not displayed to the terminal due to

set termout off

In my test, temp.lst contained:

10:56:15 SQL> SET SERVEROUTPUT ON;
10:56:15 SQL>   BEGIN
10:56:15   2      CUSTOM_PKG.get_transaction_details(10);
10:56:15   3    END;
10:56:15   4  /
SESSION DETAILS :
----------------

PL/SQL procedure successfully completed.

10:56:15 SQL> SET ECHO OFF;

There are no actual results because all ids are 100 and you are passing 10.
