As we know in MSSQL we can write below line to print some message
print 'Some Message';
How we can do same in Oracle as print not working with Oracle?
Use
DBMS_OUTPUT.put_line('Some Message');
To expand on #mhasan's answer and #AlexPoole's comment: assuming that you're executing your script using SQL*Plus you'll need to add the beginning of your script before the first DECLARE or BEGIN:
SET SERVEROUTPUT ON SIZE 1000000
SET LINESIZE 255
If you're using a tool other than SQL*Plus to run your script there will be different ways to view output written to DBMS_OUTPUT. For example, in PL/SQL Developer a "Test" window has a "DBMS Output" tab where text written to DBMS_OUTPUT can be viewed after the test script terminates.

I have an Oracle concurrent request that calls a SQLPlus program. The program itself is working correctly, but I would like to add some logging information to the concurrent request output / log in EBS.
I have tried a number of variations of:
set heading off
--set pagesize 0 embedded on
set pagesize 50000
set linesize 32767
set feedback off
set verify off
set term off
set echo off
set newpage none
set serveroutput on
dbms_output.enable(1000000);
--prepare data
EXECUTE program (&1,&2,&3,&4,&5);
--extract data
#"path/file.SQL";
fnd_file.put_line(FND_FILE.LOG,'do some logging here');
fnd_file.put_line(FND_FILE.OUTPUT,'do some logging here');
/
But everything I've tried so far results with either
no logging added to request output or log
no request output whatsoever
errors like:
SP2-0734: unknown command beginning "dbms_outpu..." - rest of line ignored.
and
PLS-00103: Encountered the symbol "ENABLE" when expecting one of the following: := . ( # % ;
Is it possible to write to the request output or log from a SQLPlus script that is called from concurrent manager?
First of all, your SQL*Plus script does not even run without your attempts at logging.
dbms_output enable(...) is missing a dot ('.').
Your anonymous PL/SQL block has no end; statement
#"path/file.SQL` is a SQL*Plus command -- it cannot be embedded in an anonymous PL/SQL block.
Aside from those basic problems, FND_FILE.PUT_LINE is only for PL/SQL concurrent programs. That is, concurrent programs whose executable points to a PL/SQL package procedure and not a .sql file under $APPL_TOP.
For SQL*Plus concurrent programs, i.e., running a .sql file under $APPL_TOP, FND_FILE.PUT_LINE does not work. Instead, your SQL*Plus output is automatically written to the request output. There is no standard way to write to the request log.
If you really need to write to the request log, you could maybe call FND_FILE.PUT_NAMES to cause FND_FILE.PUT_LINE to write to temporary files that you name. Then, knowing the concurrent request ID and the logic Oracle EBS uses to local output and log files, do a FND_FILE.CLOSE and host command to move the custom-named files you specified to the actual locations. That might work.
It'd be much better to redo your concurrent program as a PL/SQL package. Then FND_FILE works just fine. If you know how to call Java from the database, there is very little you can do in a .sql script that you cannot do in a PL/SQL package.
I have not written a .sql concurrent program in years, and I write concurrent programs all the time.
I have resolved this problem. The solution is incredibly simple - and now I'm bent out of shape because it took so long to realize.
Step 1 - SET ECHO ON
Step 2 - PROMPT whatever you want written to concurrent request output
The following sample writes 'Output is written to this folder' to the concurrent request output.
set heading off
--set pagesize 0 embedded on
set pagesize 50000
set linesize 32767
set feedback off
set verify off
set term off
set echo on
set newpage none
set serveroutput on
prompt Output is written to this folder
--prepare data
EXECUTE program (&1,&2,&3,&4,&5);
--extract data
#"path/file.SQL";
/
This is exactly what I was looking for. Maybe this will be useful to someone in another galaxy.
If this is for testing/debugging purposes, you can specify the location of the log and output files with the routine: FND_FILE.PUT_NAMES and as soon as you log all the required information you need to close the file with: FND_FILE.CLOSE
As Matthew mentioned, logging in SQL*Plus executables doesn't work well. If you can't move your code to a PL/SQL Stored Procedure for some reason, a Host script might work for you instead. From there, you can execute SQL, e.g. sqlplus -s $FCP_LOGIN ... and write log information as required.
If you just need to prepare data by PLSQL and then spool it to CSV via SQL, you can use our company's Blitz Report instead, which does this more convenient and is for free for such use. It also uses a Host type executable and calls sqlplus from there.
I'm working on a solution where several SQL and PL/SQL scripts are being run together, in a batch of sorts, via SQL*Plus.
I'm declaring SET ECHO OFF; and SET ECHO ON; at relevant points in the scripts so as to output relevant code.
Currently the output looks something like this:
SQL> DECLARE
2 ct number := 0;
3 ctChanges number := 0;
4
5 BEGIN
6 select count(*) into ct from ...
7 (...rest of code block...)
"some specific status message"
Commit executed.
We keep this output as a run-log in our build-environment, but can also access it as a plain text file.
One downside of this format however, is that if I'd like to copy a certain section of the code and run it again in an IDE (like Toad or SQL Developer), it's hard to exclude the line numbers.
Is it possible to tell SQL*Plus to output the code as above, but without including the line numbers?
You can use options sqlnumber and sqlprompt:
set sqlprompt ''
set sqlnumber off
SET SQLN[UMBER] {ON|OFF}
SET SQLNUMBER is not supported in iSQL*Plus
Sets the prompt for the second and subsequent lines of a SQL command or PL/SQL block. ON sets the prompt to be the line number. OFF sets the prompt to the value of SQLPROMPT.
I have a pl/SQL query that has a variable .
I want DBMS_OUTPUT.PUT_LINE to a file used on the machine (linux)
Does someone know how to do this?
You need to put some pieces together. Here is my inspiration: DBMS_OUTPUT.PUT_LINE not printing
a) put your plsql in an sql script, e.g. d.sql - the key here is set serveroutput:
set serveroutput on size 30000;
begin
DBMS_OUTPUT.PUT_LINE('my line');
end;
/
exit
b) Then write another script - ksh this time - containing:
sqlplus / #d.sql > output.txt
If you want to restrain what displays from sqlplus, then read appropriate documentation about set statement
This code compiles, but in TOAD it won't show the "hi wo" output
CREATE OR REPLACE PROCEDURE AdelTest IS
tmpVar NUMBER;
BEGIN
DBMS_OUTPUT.ENABLE(100: in INTEGER);
DBMS_OUTPUT.PUT_LINE('hi wo');
tmpVar := 0;
EXCEPTION
WHEN NO_DATA_FOUND THEN
NULL;
WHEN OTHERS THEN
--consider logging error then r-raise
RAISE;
END AdelTest;
How do I show the output(similar to how println shoots to console in Java ) ?
You need to enable DBMS Output. If working in the Editor right-click and choose DBMS Output off of the Desktop flyout menu. There's a button that is red if it's disabled. Click it and it will turn green. Then execute your code. Output will display there. If you are working outside of the Editor (in Schema Browser for instance) select DBMS Output off of the main Toad View menu. Enable your output there. Output will display in that window.
You can also view server output if for some reason DBMS output window is not getting enable. use QSR editor embedded within toad for oracle edition..
How to use
select the code in place
Editor > Execute SQL via QSR
have the set serveroutput on as first statement in QSR window and run..
now it will show output in window..
Hope it helps!!!

Need to enable the Automatically poll for output after execution under DBMS Output
DECLARE
v_text VARCHAR2(20); -- declare
BEGIN
v_text := 'Hello World'; --assign
dbms_output.Put_line(v_text); --display
END;
DECLARE
V_NUMBER NUMBER :=23;
BEGIN
LOOP
V_NUMBER:=V_NUMBER+1;
EXIT WHEN V_NUMBER:=25;
--Some kind of function to be applied for printing and nesting lines into CSV or TEXT file.
END LOOP;
COMMIT;
END;
Scripting an Oracle SQL Query for Creating a CSV or Text Typed File Output
Consider running this from a SQL Plus session and use the SPOOL command. All output of the SQL command that follows will be written to the file name you specify.
If you need to append your results each successive time the SQL commands are run, then an OS level command would work appropriately when invoking this sqlplus executable block of PL/SQL:
Where the file name of this script is: "sample_csv_out.sql"
DECLARE
v_total_columns constant number:= 3; -- Number of columns queried
v_column_counter number;
v_csv_record varchar2(1000);
c_csv_column_format constant varchar2(15):=
'<<COLUMN1_VAL>>,<<COLUMN2_VAL>>,<<COLUMN3_VAL>>';
cursor result_cur is
SELECT column1, column2, column3
FROM tablea
WHERE column1 = ... ;
BEGIN
v_csv_record:= 'COLUMN1,COLUMN2,COLUMN3';
dbms_output.put_line (v_csv_record);
FOR i in result_cur LOOP
v_csv_record:= replace(c_csv_column_format, '<<COLUMN1_VAL>>', i.column1);
v_csv_record:= replace(v_csv_record, '<<COLUMN2_VAL>>', i.column2);
v_csv_record:= replace(c_csv_record, '<<COLUMN3_VAL>>', i.column3);
dbms_output.put_line(v_csv_record);
END LOOP;
END;
So, for example in a WINDOWS O/S environment, the call to append the output to a specific file name would be:
C:\> sqlplus sample_csv_out.sql >> mycsv_out.csv
The >> notation instructs the operating system to pipe the output of running sample_csv_out.sql via a sqlplus session.
The command DBMS_OUTPUT does the rest. If you need more details, see more Oracle documentation on DBMS_OUTPUT.
COMMENTS: I chose the RECORD STRING TEMPLATE approach to make this script a little more flexible and reusable. I recommend to keep any data manipulation logic within the CURSOR statement. Often when the two are mixed, it gets harder to debug any typos in syntax within a long string of values.
The construction of an output record was also designed to reduce typos, mistakes and frustration... if there are more than 3 columns in your own scripts, adding another element to the output string is mostly a cut-and-paste operation. Likewise with the "header" row (column titles).
