Printing the value of a variable in SQL Developer

I wanted to print the value of a particular variable which is inside an anonymous block. I am using Oracle SQL Developer. I tried using dbms_output.put_line. But it is not working. The code which I am using is shown below.

SET SERVEROUTPUT ON

DECLARE

  CTABLE USER_OBJECTS.OBJECT_NAME%TYPE;
  CCOLUMN ALL_TAB_COLS.COLUMN_NAME%TYPE;
  V_ALL_COLS VARCHAR2(500);

  CURSOR CURSOR_TABLE
    IS
    SELECT OBJECT_NAME 
    FROM USER_OBJECTS 
    WHERE OBJECT_TYPE='TABLE'
    AND OBJECT_NAME LIKE 'tb_prm_%';

  CURSOR CURSOR_COLUMNS (V_TABLE_NAME IN VARCHAR2)
    IS
    SELECT COLUMN_NAME
    FROM ALL_TAB_COLS
    WHERE TABLE_NAME = V_TABLE_NAME;

BEGIN

  OPEN CURSOR_TABLE;

  LOOP
    FETCH CURSOR_TABLE INTO CTABLE;
    EXIT WHEN CURSOR_TABLE%NOTFOUND;

    OPEN CURSOR_COLUMNS (CTABLE);

    V_ALL_COLS := NULL;

    LOOP
      FETCH CURSOR_COLUMNS INTO CCOLUMN;
      V_ALL_COLS := V_ALL_COLS || CCOLUMN;
      IF CURSOR_COLUMNS%FOUND THEN
        V_ALL_COLS := V_ALL_COLS || ', ';
      ELSE
        EXIT;
      END IF;
    END LOOP;

    DBMS_OUTPUT.PUT_LINE(V_ALL_COLS);

  END LOOP;
  CLOSE CURSOR_TABLE;

END;

And I am getting the output only as anonymous block completed.

In newer versions of SQL developer, there is no more separate output view that you need to show, instead it's always there, as a tab. Below your list of tabs (which SQL developer calls "windows", so for example two SQL input areas), there is another list of tabs, called "SQL", "Output" and "Statistics". The output will not open automatically, you need to click on the tab.

1 ) Go to view menu.
2 ) Select the DBMS_OUTPUT menu item.
3 ) Press Ctrl + N and select connection editor.
4 ) Execute the SET SERVEROUTPUT ON Command.
5 ) Then execute your PL/SQL Script.

There are 2 options:

set serveroutput on format wrapped;

or

Open the 'view' menu and click on 'dbms output'. You should get a dbms output window at the bottom of the worksheet. You then need to add the connection (for some reason this is not done automatically).

DECLARE

  CTABLE USER_OBJECTS.OBJECT_NAME%TYPE;
  CCOLUMN ALL_TAB_COLS.COLUMN_NAME%TYPE;
  V_ALL_COLS VARCHAR2(5000);

  CURSOR CURSOR_TABLE
    IS
    SELECT OBJECT_NAME 
    FROM USER_OBJECTS 
    WHERE OBJECT_TYPE='TABLE'
    AND OBJECT_NAME LIKE 'STG%';

  CURSOR CURSOR_COLUMNS (V_TABLE_NAME IN VARCHAR2)
    IS
    SELECT COLUMN_NAME
    FROM ALL_TAB_COLS
    WHERE TABLE_NAME = V_TABLE_NAME;

BEGIN

  OPEN CURSOR_TABLE;
  LOOP
    FETCH CURSOR_TABLE INTO CTABLE;

    OPEN CURSOR_COLUMNS (CTABLE);
    V_ALL_COLS := NULL;
    LOOP

      FETCH CURSOR_COLUMNS INTO CCOLUMN;
      V_ALL_COLS := V_ALL_COLS || CCOLUMN;
      IF CURSOR_COLUMNS%FOUND THEN
        V_ALL_COLS := V_ALL_COLS || ', ';
      ELSE
        EXIT;
      END IF;
    END LOOP;
   close CURSOR_COLUMNS ;
    DBMS_OUTPUT.PUT_LINE(V_ALL_COLS);
    EXIT WHEN CURSOR_TABLE%NOTFOUND;
  END LOOP;`enter code here`
  CLOSE CURSOR_TABLE;

END;

I have added Close of second cursor. It working and getting output as well...

SQL Developer seems to only output the DBMS_OUTPUT text when you have explicitly turned on the DBMS_OUTPUT window pane.

Go to (Menu) VIEW -> Dbms_output to invoke the pane.

Click on the Green Plus sign to enable output for your connection and then run the code.

EDIT: Don't forget to set the buffer size according to the amount of output you are expecting.

You need to turn on dbms_output. In Oracle SQL Developer:

  1. Show the DBMS Output window (View->DBMS Output).
  2. Press the "+" button at the top of the Dbms Output window and then select an open database connection in the dialog that opens.

In SQL*Plus:

 SET SERVEROUTPUT ON
