Using SET SERVEROUTPUT ON in procedure

Hi,
Can I use SET SERVEROUTPUT ON inside a procedure. The reason is I am building a procedure in Toad and will execute in SqlPlus. In future I will only use SqlPlus to execute and view my result.

No.
Although you can use DBMS_OUTPUT.ENABLE, it only re-enables output that was previously disabled (with DBMS_OUTPUT.DISABLE). It does not alter the current SQL*Plus SERVOUTPUT setting.
For example,
SQL> set serveroutput on size 1000000
SQL>
SQL> begin
2      dbms_output.enable(1000000);
3      dbms_output.put_line('Eat more bananas');
4 end;
5 /
Eat more bananas
PL/SQL procedure successfully completed.
SQL> set serveroutput off
SQL>
SQL> r
1 begin
2      dbms_output.enable(1000000);
3      dbms_output.put_line('Eat more bananas');
4* end;
PL/SQL procedure successfully completed.
SQL> show serverout
serveroutput OFF

Try to put serveroutput statement before spool statement.

The preference for the path is not working, this is a bug and is logged.
For set server output: The output is written to the DBMS Output tab and you need to use the toggle on that screen to set server output on.

Set "serveroutput on" for the current session.

I'm still new to PL/SQL and I use "*SET SERVEROUTPUT ON SIZE 100000"* always before I run a PL program block to get dbms_output. I really need to know why should we specify a size in this line & what that size will be applied for. Also I need to know whether there is any possibility to set serveroutput enabled for the current session, rather than running this code line before each and every PL block.
I Tried *"ALTER SESSION SET SERVEROUTPUT ON SIZE 1000000"* ; But it was not successfully executed.
Thanks!

SET SERVEROUTPUT ON TOAD

hi
how can I use "SET SERVEROUTPUT ON" clause on toad

Same as you would in SQL*Plus: Simply type SET SERVEROUT ON in the SQL editor and run with F5.
Alternatively there's a button on the DBMS_OUTPUT desktop panel which should light up green. Output will then be generated when the statement is run with F9.

Set serveroutput on handling at Package/Procedure.

Hi,
Can we handle the set serveroutput on in package it self ?, what is the scenario we need to do for this.
I need to print some values after executing the package automatically.... please let me know further more information requried.
please let me know what DBMS_OUTPUT.ENABLE(10000000) will be do...?
Thanks,
Pavan K

DBMS_OUTPUT.ENABLE(10000000) will turn on dbms_output, but unless the client knows to check for output you won't see anything.
To make SQL*Plus poll for output you need to use the SET SERVEROUTPUT ON SQL*Plus command to tell SQL*Plus to look for output. You could then use DBMS_OUTPUT.DISABLE to turn it off programatically until you need it turned back on.
Otherwise you need to poll for output yourself by issuing calls to DBMS_OUTPUT.GET_LINE[s]

Hi,
you could use Dynamic SQL /Execute immediate to run DDL from a stored procedure.
http://download-uk.oracle.com/docs/cd/B10501_01/appdev.920/a96624/11_dynam.htm
Could you please tell why do you want to create a materialized view in stored procedure ?
How frequently you will runt this procedure . It would is better to create a MV once and use it.
thanks

Set serveroutput on;

I have 10.2.0.1.0 on Windows XP and have set serveroutput on on sqlplus. However, I don't see the out put from dbms_output.put_line('xxxxxx'); the dbms_output.put_line() is not in IF or ELSE condition.
Can anyone please shed a light? Thanks in advance.

Dear 782150,

Set Serveroutput On throught PL/Sql

Hi All,
In order to display output through DBMS_output.put_line one need to do set serveroutput on, I want to do that through PL/SQL as application I work on user forget to do so. I want to come over that. Although its useful sometimes as application supports both ways even if for some condition I don't want to display output and same code can be used for displaying output.Any suggestions
thanks

How is the application executing the pl/sql with the dbms_out statement in it?
Either the sqlplus script that contains the code should have a set serveroutput on size nnnn right before the pl/sql code is executed OR
the application should read the dbms_output buffer using the dbms_output.get_line procedure and use its own functionality to display the output. In this case you enable the buffer using dbms_output.enable and when done dbms_output.disable. We have done this in pro*c programs.

DBMS_OUTPUT & set serveroutput on

Hello:
In my APEX app I am executing a procedure. Within this procedure I have DBMS_OUTPUT.PUT_LINE displaying results after each function.
In order to see the output which is produced by DBMS_OUTPUT, I have to type, set serveroutput on. When I run my procedure in SQL Developer, I see all the results.
When I run my APEX app with this procedure, I am not able to see the results of the DBMS_OUTPUT. It is important that the user see the results after they submit the parameter for the procedure.
Is there a way that I can display the results of DBMS_OUTPUT after my user clicks the SUBMIT button?
Thanks in advance.

Hi,
the following example copies the DBMS_OUTPUT messages into a table MESSAGE; instead of this
you can also use an APEX collection or wwv_flow.debug or some other thing ...
declare
v_lines dbms_Output.chararr;
v_numlines pls_integer := 100;
begin
dbms_output.enable; -- activate - equivalent to "set serveroutput on"
dd.change_patient.add_patient_new(:P2_ORG_NUM);
-- get the messages
dbms_output.get_lines(v_lines, v_numlines);
-- insert the messages into a table
for i in 1..v_numlines loop
insert into MESSAGE values (v_lines(i));
end loop;
end;

PL/SQL set serveroutput

Hi
I'm trying to print an XML document into a PL/SQL region.
Here's the region source:
declare
queryCtx DBMS_XMLquery.ctxType;
result CLOB;
begin
queryCtx := DBMS_XMLQuery.newContext('select * from mytable');
result := DBMS_XMLQuery.getXML(queryCtx);
printClobOut(result);
DBMS_XMLQuery.closeContext(queryCtx);
end;
And here's the 'printClobOut' procedure:
PROCEDURE printClobOut(result IN OUT NOCOPY CLOB) is
xmlstr varchar2(32767);
line varchar2(2000);
set serveroutput on
begin
xmlstr := dbms_lob.SUBSTR(result,32767);
loop
exit when xmlstr is null;
line := substr(xmlstr,1,instr(xmlstr,chr(10))-1);
dbms_output.put_line('| '||line);
xmlstr := substr(xmlstr,instr(xmlstr,chr(10))+1);
end loop;
end printClobOut
For some reason it doesn't like the 'set serveroutput' command, and gives me this error:
ERROR at line 4: PLS-00103: Encountered the symbol "ON" when expecting one of the following: := . ( @ % ; not null range default character The symbol "; was inserted before "ON" to continue.
If I don't have that command in there, it doesn't print anything out.
Any ideas?
Cheers
-Dave

David,
That statement is not part of the PL/SQL language. It's used only in SQL*Plus to enable output when using dbms_output. You need to use htp.p with the web components instead of dbms_output, and htf.escape_sc within that if necessary to escape special characters, if any, e.g., htp.p(substr(xmlstr,1,instr(xmlstr,chr(10))-1)) or htp.p(htf.escape_sc(substr(xmlstr,1,instr(xmlstr,chr(10))-1))).

Two related questions: using htmldb_Get to call stored procedure and passing in an array of items

I have the need to save dynamically generated ApEx items via AJAX. I am using APEX_ITEM API to generate the items. At run-time, I have no idea how many of items will be generated on the page, but I know that they will all have discreet and distinct "name" attributes, i.e. f01, f02, f03, etc. As a basic example, if I have to generate a select list, I know that the "p_idx" parameter of the APEX_ITEM call is say "3", so all select lists that get generated will have a "name" attribute in the DOM of "f03", all text items will be "f01", etc.
I want to save this data to the database via AJAX. It is typical to call the standard htmldb_Get javascript function for use of an on-demand process, but I am interested in using the rarely-called-upon "procedure" and queryString" options of that javascript function so that I can build the queryString on the fly based on what is on the DOM when the tries to save the data they entered into these APEX_ITEM-generated items. Does anyone have any good examples of how to use the "procedure" and "queryString" parameters of the htmldb_Get javascript function?
I have found a smattering of some blogs, posts, etc. online related to this, but mostly just people regurgitating the documentation. I found this post (https://forums.oracle.com/thread/2549237) which had a glimpse of hope to be able to pass an array (which is something I will need) as a parameter, but would like someone to sanity check this before I go down that road.
Shane.
ApEx 4.2.1

Shane
Since you mention you are on APEX 4.2 I would recommend using apex.server.process which is the documented replacement of the officially undocumented htmldb_Get.
In the documentation it is set that the first parameter is the ajaxidentifier but it actually is the process name.
The data object would be something like
var lData ={f01 : get_value_array('f01')}
Where get_value_array is
function get_value_array(pColumnName) {
var l_values =[];
apex.jQuery('[name="'+pColumnName+'"]').each(
   function(){
    var l_value;
    l_value = apex.item(this.id).getValue();
    l_values.push(l_value);
return l_values
For a working example see this demo.

Using VIEW inside a stored procedure

Hi,
So I have a View designed in one file that validates someone who is authorized.
Then I have a stored procedure to display authorized stationeries created before a given date. Its takes a parameter @CreatedOn.
How can I use VIEW in my stored procedure so I can display all the authorized which are set 1 before a given date?
My VIEW:
ALTER VIEW vw_AuthorizedStationeries AS
SELECT Authorized
FROM dbo.Stationeries
WHERE Authorized = 1
And my stored procedure:
CREATE PROCEDURE usp_stationeries (@CreatedOn datetime)ASBEGINSELECTFROMENDGO
Thanks!

Try something like below, You need to replace CreatedDate column with appropriate date column in your table.
1. Alter the view to get the required date:
ALTER VIEW vw_AuthorizedStationeries AS
SELECT Authorized, CreatedDate
FROM dbo.Stationeries
WHERE Authorized = 1
2. Alter SP:
CREATE PROCEDURE usp_stationeries (@CreatedOn datetime)
AS
BEGIN
SELECT Authorized
FROM vw_AuthorizedStationeries
WHERE CreatedDate <= @CreatedOn
END
GO
OR
You can pull required information directly from your table:
CREATE PROCEDURE usp_stationeries (@CreatedOn datetime)
AS
BEGIN
SELECT Authorized
FROM dbo.Stationeries
WHERE CreatedDate <= @CreatedOn and Authorized = 1
END
GO

Using temporary tables in stored procedures

Suppose that I have created a temporary table in a stored procedure using an "EXECUTE IMMEDIATE" statement. When I compile the procedure, that table is not created yet, so the compiler says that the table does not exist.
What is the way of using temporary tables in stored procedures?

It's a good practice to avoid using DDL statements being executed from stored procedures. "Truncate Table" via dynamic SQL from stored procedure is a different story and is useful in DSS environments.
But if you insist on "creating" tables using Dynamic SQL from Stored Procedures then you must also embed your DML statements in Dynamic SQL to avoid compilation errors.
Example:
Create or Replace Procedure Proc_TestDynamicSQL is
Begin
Execute Immediate 'Create table myTable as select * from user_tables' ;
Execute Immediate 'Update myTable set table_name = ''Test'' ' ; --two single quotes before and after the string "Test"
End;
In this case, Oracle wouldn't care about the table references during compilation.
