In Oracle SQL*Plus, how can the output (to the terminal) be turned off?
This is for interactive mode, not running a script.
Example:
SELECT 1 from dual;
-- don't want to see the resulting row(s) !
var c refcursor
exec some_procedure(:c);
print
-- don't want to see the resulting row(s) variable C !
Primarily looking for solution on Windows, Oracle DB version 11.2.
set autotrace traceonly The query still runs. The results are sent to the client, but are not displayed. The plan and statistics are displayed however. The statistics requires access to certain v$ views. To run without the statistics, set autotrace traceonly explain.
You can't, really; the options that might help (like set termout off, which you're presumably already familiar with) only apply when running a script.
I'm not sure it really makes sense for the print command, but if you really want to run a query without seeing the output could just put it in a PL/SQL block:
SQL> set feedback off
SQL> set timing on
2 begin
3 for r in (select 1 from dual) loop
4 null;
5 end loop;
6 end;
7 /
Elapsed: 00:00:00.00
SQL>
The null; is needed because you have to do something inside the loop. The compiler doesn't optimize it out - it does still execute the query and retrieve the results, at least as far as I can tell; a slightly more useful query like select table_name from all_tables takes non-zero time - 1.45 seconds on my system.
You could loop over a ref cursor result too I suppose, if you wanted to time the equivalent of the print fetches:
SQL> var c refcursor
2 begin
3 open :c for select table_name from all_tables;
4 end;
5 /
Elapsed: 00:00:00.17
SQL> declare
2 t all_tables.table_name%type;
3 begin
4 loop
5 fetch :c into t;
6 exit when :c%notfound;
7 end loop;
8 close :c;
9 end;
10 /
Elapsed: 00:00:00.10
I went with a script like this (in a file that I execute via #):
var c refcursor
set timi on
exec proc1(:c);
set feedback off
set timi off
exec DBMS_OUTPUT.PUT_LINE(' before PRINT ' || systimestamp);
set termout off
print
set termout on
exec DBMS_OUTPUT.PUT_LINE(' after PRINT ' || systimestamp);
set feedback on
set timi on
rollback;
exit
Set termout off also suppresses the timing output, so I added the PUT_LINEs (could have used a select systimestamp from dual too).
I guess there is no short and elegant solution.

I'm trying to execute a script on SQL PLus, it's simple.
SET serveroutput ON;
DECLARE
mode NUMBER(1) := 1;
IF (mode = 1) THEN
prompt 'HERE'
END IF;
prompt 'fim'
I call the script from SQLPlus using sqlplus user/pw#db and #myscript.sql after a successful connection. But the output is strange for me:
Conectado a:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
With the Partitioning, OLAP and Data Mining options
SQL> #myscript.sql
9
10
11
And it continues to print this sequence indefinitely.
What am I doing wrong?
From your edited question... you have to terminate the PL/SQL block with a / on a new line to make it end and run, otherwise SQL*Plus will keep prompting for more lines of code (which is the numbers you're seeing). The documentation shows how to run PL/SQL blocks. And prompt is a SQL*Plus command so you can't use it inside a PL/SQL block. You also don't have your block syntax right:
SET serveroutput ON;
DECLARE
mode NUMBER(1) := 1;
BEGIN
IF mode = 1 THEN
DBMS_OUTPUT.PUT_LINE('HERE');
END IF;
END;
/
prompt fim
You cannot use sqlplus command in plsql.We can use dbms_output instead which will display the output in SQL prompt
SET serveroutput ON;
DECLARE
mode NUMBER(1) := 1;
BEGIN
IF (mode = 1) THEN
dbms_output.put_line('HERE');
END IF;
dbms_output.put_line('fim');
END;
/
Go to your oracle home Oracle\product\<version>\client_2\sqlplus\admin\glogin.sql and add the following lines to enable printing globally,
SET ECHO ON;
SET TERM ON;
WHENEVER SQLERROR EXIT FAILURE ROLLBACK;
SET DEFINE OFF;
I'm having issues with spooling out results from queries, more or less it shows always no real cost, shows rows as one and no cost or anything added, and not the statistics of the actual query.
I'm using this setup:
current_date=$(date +%Y-%m-%d)
sqlplus -S "Username/password#mydatabase.bag" <<EOF >/output/Testoutput_$current_date.log
set verify off;
set colsep ,
SET AUTOTRACE ON
set headsep off
set pagesize 0
set trimspool on
set termout off
col v_spool noprint new_value v_spool
select 'Spoolfile'||
to_char(sysdate,'yyyy_mm_dd_hh24_mi_ss')||'.csv' v_spool from dual;
set termout on
spool /folder/subfolder/&&v_spool
set lines 12345 pages 12345;
EXPLAIN PLAN SET statement_id = 'example_plan1' FOR
select * from dbms.database1_1 where numberline like '%4214%';
SET TIMING OFF
spool off
EXIT
EOF
My wish is to somehow get the explain results spooled to a file, what do I need to modify to achieve this or there is a different approach?
If you try running this in SQL*Plus:
EXPLAIN PLAN SET statement_id = 'example_plan1' FOR
select * from dbms.database1_1 where numberline like '%4214%';
You'll notice that it just outputs:
Explained.
You have to actually select the results of the EXPLAIN PLAN using DBMS_XPLAN - that will get output and spooled to your file.
-- generate the explain plan
EXPLAIN PLAN SET statement_id = 'example_plan1' FOR
select * from dbms.database1_1 where numberline like '%4214%';
-- actually display the results
select plan_table_output
from table(dbms_xplan.display('plan_table',null,'typical'));
Updating my question:
When I run this query from unix using sqplus it gives me duplicate outputs
Query:
select sysdate from dual
/
/*comment*/
EXIT
Output
SQL> #tt.sql
12-AUG-16
12-AUG-16
Here is what is happening.
The first two lines (including the /) form a complete SQL statement. SQLPlus executes it and displays the first line.
Then /*comment*/ is OUTSIDE the SQL statement. So it is interpreted by SQLPlus, not as a SQL comment.
The point is, comments in the SQLPlus scripting language have a different syntax; they are lines that begin with REM[ARK]. /*comment*/ is NOT a comment in SQLPlus.
Instead, in SQLPlus, a slash / as the first character on a new line means repeat the last SQL command (if after that you had SQLPlus commands, like DESCRIBE or COLUMN, those are ignored). Everything AFTER the slash is ignored. To convince yourself of this, try again, but with the comment line changed to /*comment* (delete the second slash). You will see the same result.
Then you have the command EXIT, but since it is NOT followed by a slash, it is not seen as a completed command. If I copy and paste your code in my SQLPlus window, I get the screenshot below. However, if at this point you press ENTER (or if this was in a sql script and not copied and pasted from a text editor), the SQLPlus window would shut down.
Hope this helps!

How to execute copy from command inside a plsql block?
E.g. I have copy from test/test#test insert emp using select * from emp;
How can I call this in a plsql block? I have tried with
execute immediate 'copy from test/test#test insert emp using select * from emp';
However when I execute my script which has plsql block gives me
ORA-00900: invalid SQL statement
How can I resolve this issue
COPY is a SQL*Plus command. So it only works in the SQL*Plus client. Find out more.
EXECUTE IMMEDIATE is a PL/SQL command to run dynamic calls, and it only recognises SQL and PL/SQL.
"I am executing sqlscript from sqlplus"
Yes, but you are calling COPY in an anonymous block, so that's with a PL/SQL scope; which means PL/SQL and SQL only.
The way to do this is with a shell script. These are operating system dependent, but something like this would work on a Linux environment.
#!/bin/bash
echo Please enter local Username:
read USERNAME
echo "Please enter local Password:"
read -s PASS
SID=${ORACLE_SID}
if [ "${ORACLE_SID}" != 'TEST' ]
then
sqlplus -s -l $USERNAME/$PASS#$SID << EOF
copy from test/test#test insert emp using select * from emp
exit
EOF
else
echo "Can't copy from TEST to TEST"
fi
Obviously this is just a wild guess at what your program actually does, but I hope you can understand the principle.
In a plsql code if we directly use the command as follows shall serve the similar output
begin
insert into emp1 select * from emp;
end;
emp1 is target table
emp is source table
There are similar ask where one wants to create blank structure or structure with data for backup kindly of activity.Refer link https://oracle-concepts-learning.blogspot.com/2019/09/copy-table-structure-or-data.html
1) Creating blank structure from existing table
--Execute on sql prompt
begin
execute immediate 'create table emp1 as select * from emp where 1=2';
end;
--Execute on sql prompt
select count(1) from emp1;
2) Creating structure from existing table with data
--Execute on sql prompt
begin
execute immediate 'create table emp1 as select * from emp';
end;
--Execute on sql prompt
select count(1) from emp1;
I have fairly simply code ..running in Oracle Virtualbox. However for some reason it is not displaying pl/sql output.
Here is code snippet
SQL> set serveroutput on
SQL> list
1 Create or Replace procedure mytz
2 IS
3 v_mytz TIMESTAMP WITH TIME ZONE DEFAULT '2013-05-05 12:00:00 AM';
4 BEGIN
5 DBMS_OUTPUT.PUT_LINE ('Default timestamp is ' );
6* end mytz ;
SQL> /
Procedure created.
SQL>
Is there anything I need to do special to see the output on SQL prompt ?
You have to actually run the procedure, not just create it, e.g.:
set serverputput on
exec mytz;
The set serveroutput SQL*Plus command has to be in the session the procedure is executed, not the one where it is created (if they are different).
You are not showing the value of your variable at the moment; maybe you wanted this?
dbms_output.put_line('Default timestamp is: ' || v_mytz);
