Why no output when PLSQL Anonymous block completes? [duplicate]

Answer 1

Yes, this is correct. You need to use before this block:

SET SERVEROUTPUT ON

Then, message get displayed on window.

Else we can check in SQL Developer select "View" -> "DBMS Output".
and in PLSQL developer under the OutPut tab we can check message.

Answer 2

Viewing the DBMS_OUTPUT depends on the program.

SQL*Plus and Oracle SQL Developer

Run SET SERVEROUTPUT ON; first. This is all that's necessary in SQL*Plus or recent versions of Oracle SQL Developer.

SET SERVEROUTPUT ON;
begin
    dbms_output.put_line('Testing output');
end;
/

PL/SQL Developer

Output is automatically detected and displayed in the "Output" tab.

Answer 3

Yes. There is way to see output in SQL Developer.

Click ->View->Dbms Output and then click + symbol on Dbms output window. now you can run the procedure and can see output.

Answer 4

If you are getting "anonymous block completed" while executing the procedure by typing "EXECUTE ;" then run the below command & again execute the procedure. command is

SET SERVEROUTPUT ON;

Answer 5

Yes, in Oracle SQL Developer put the statement:

SET SERVEROUTPUT ON;

just before your DECLARE keyword and this should work.

I couldn't find View -> DBMS Output and I'm using version 1.5.5.

Answer 6

`The following statement will give the possible solution try this out

SET SERVEROUTPUT ON;

Then Run this code will get the following output

declare
a integer :=10;
b integer :=20;
c integer;
f real;
begin
c := a+b;
dbms_output.put_line('value of c: ' || c);
f := 70.0/3.0;
dbms_output.put_line('value of f: ' || f);

end; /

The code will give the following output

value of c: 30 value of f: 23.3333333333333333333333333333333333333
