Setting session using pl/sql

How to set and retrieve session using pl/sql?Can anyone help me?

This is the wrong forum for SQL or PL/SQL questions.
1. Post your question in the SQL and PL/SQL forum
https://forums.oracle.com/forums/forum.jspa;jsessionid=8d92100c30d7960321c250bf4adeaa5dcac037eb147c.e34SbxmSbNyKai0Lc3mPbhmSbNaLe0?forumID=75&start=0
2. Edit this thread and post the link to your new question.
3. Mark this thread ANSWERED so people will follow up in the other forum.
When you post your new question provide your 4 digit Oracle version (result of SELECT * FROM V$VERSION). You will also need to explain what you mean by 'set and retrieve' session. A session is created when a logon is successful so 'set' and 'retrieve' only have meaning in terms of trying to set or retrieve session parameters that may be in effect.

..snipped..The code should look as follows:

i integer;

--// purpose of the SQL is simply to check if such a row exist -
--// no data from the row needs to be fetched

--// if the SQL succeeded, then the row exists and matches
--// the authentication details
return( 0 );
exception when NO_DATA_FOUND then
--// SQL failed to find a row - authentication details do
--// not exist
return( 1 );
end;No need to fetch data unnecessarily. No need too check the fetched data when the column values are already checked via the SQL filter condition (predicate).
No need to return a flag variable as a freely formatted text string containing Successful Login and login failed. That is not a robust design to use a string variable like that. Use boolean for true/false. Or use integer values 0/1.
This is my function get_login_details.And I need to get this 'o_mesg' in other java file also.Standard PL/SQL call from Java. The SQL string to execute contains an anonymous PL/SQL and needs to use bind variables. E.g.
begin
:result := AuthenticateUse( :userName, :userPassw, :userGroup );
end;
Can you suggest the right way, how I can get this variable in other pages?That depends on whether there is database session state. If there is, authentication can be done once only via a trusted context, that specifies whether the session is authenticated.
If this is done from an app server that uses a db session pool and stateless db sessions, the state needs to be kept in the app server.
Do you understand what stateful versus stateless db sessions are, and what the differences are?

Hello,
In fact you may use orakill it's an Oracle utility for Windows so as to Kill the thread corresponding
to the session.
It's equivalent to a kill -9 on Unix.
Please find here a link about the use of orakill:

Hope this help.

How to set ORACLE_HOME used by SQL Developer?

I need to use OCI/Thick driver with SQL Developer to get OS authentication working. I have 64-bit windows and 64-bit oracle installed. I also have 32-bit instant client in another ORACLE_HOME, because the libs of 64-bit ORACLE_HOME won't work with SQL Developer. Quite trivial setup if the SQL Developer would just take the hint an start using the right ORACLE_HOME. I have tried making a start.bat containing following...
set ORACLE_HOME=C:\oracle\product\11.1.0\instantclient_11_1
start sqldeveloper.exe
..but it doesn't have any effect. I can't change ORACLE_HOME in registry, because it would mess up other services requiring 64-bit oracle.

It might be a little late for the original post, but maybe someone else will need it:
I found that the way to solve such issue is by specifying the TNSNAMES of the wanted oracle_home. That'll do it.
It could be done in Tools -> Preferences -> Database -> Advanced -> Tnsnames directory.

Open telnet session using PL/SQL

Dear all
I have made a function that returns a value when a remote server runs a specific process. In order to find this, I would like to run a telnet command along with some grep parameters. This can be done using a Java class, but it is not very functional! Is this a way to do using only PL/SQL?
Thanx in advance

I know there are a couple of Java telnet clients out there, I'm not sure whether they support the JDK in your database. What version of Oracle are you using? The other option would be to write a script that does whatever you want to do and just call the batch file.

SET Role and PL/SQL

Hello folks
Is there a way/workaround to do a SET ROLE using PL/SQL ? Please advise

No - you cannot set roles within a definer's rights procedure.
See How Roles Work in PL/SQL Blocks in the Database Security doc
http://docs.oracle.com/cd/B28359_01/network.111/b28531/authorization.htm
>
How Roles Work in PL/SQL Blocks
The use of roles in a PL/SQL block depends on whether it is an anonymous block or a named block (stored procedure, function, or trigger), and whether it executes with definer's rights or invoker's rights.
Roles Used in Named Blocks with Definer's Rights
All roles are disabled in any named PL/SQL block (stored procedure, function, or trigger) that executes with definer's rights. Roles are not used for privilege checking and you cannot set roles within a definer's rights procedure.
>
And be careful to heed this warning about LOGON triggers (see Using triggers in the PL/SQL doc - http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/triggers.htm)
>
•If you use a LOGON trigger to monitor logons by users, include an exception-handling part in the trigger, and include a WHEN OTHERS exception in the exception-handling part. Otherwise, an unhandled exception might block all connections to the database.

OBIEE 10g - Can I use logical SQL to set variable?

I am trying to set value of a session variable in the Advanced tab Prefix box of a request.
Assigment of absolute value like this is working good:
SET VARIABLE MYVAR=1;
Can I set the variable using logical SQL? Something like:
SET VARIABLE MYVAR = (SELECT table1.col1 from catname where table1.col2=1)
Thanks in advance.

Hi,
You can create a session variable or dynamic variable in the RPD and try using it in here at the Advanced Tab prefix.
But still check yourself if you need multiple values returning in the SQL statement.
Hope this is helpful/ useful.

How to set the value of application item using pl/sql in application process

Hi guys,
I want a global variable (application item) whose value will be set at the start when a user logs in to the application. The value will be retrieved from database using a sql query. I do not know the exact syntax to set the value of application item in application process. Also i want to know in which type of application process should i use to set the value of application item when a user starts a session. The value of application item varies from user to user.
Please help.
I am using apex 4.2
Regards,
Waqas

You can use the application item as bind-variable with its name. ie. your application item is named G_MY_APPLICATION_ITEM, then you can access/set it using :G_MY_APPLICATION_ITEM.
For example
BEGIN
    -- assign like a variable
    :G_MY_APPLICATION_ITEM := 'LARRY';
    -- use in a SQL statement
    SELECT WHATEVER_COLUMN
      INTO :G_MY_APPLICATION_ITEM
      FROM MY_TABLE
     WHERE USERNAME = :APP_USER
END;

Using the Set Session Info to populate Custom Variable

Hey everybody, I'm trying to setup a Set Session Info step so when a caller presses 1 for instance to go to a specific department I can go into the database and see how many callers pressed a certain button.
Here's what I've done so far, I've setup a Session called session_info with the value of null. At the very beginning of the script it shows session_info = Get Contact Info --Triggering Contact--, Session)
Then in the menu field when a caller presses 1 I have the Set Session Info step with the Session being session_info and then in the Context tab I have "_ccdrVar3" for the name and "1" for the value.
The script doesn't fail it's just not populating any Custom Variable with any data.
Also I've tried using the Set Enterprise Call Info and using a value of 1 and then Call.PeripheralVariable3 for the name. Not sure what the proper way to do this is. Anybody have any ideas?

Hi
You don't need a session var.
You just need to use 'set enterprise data' to set a call.peripheralvariable to what you like.
The data goes straight into the contactcalldetail table.. You can check it by doing:
run uccx sql db_cra select * from contactcalldetail where customvariableX = 'yoursetting'
Where 'yoursetting' is what you set the ent data to, and customvariableX is the var you use (e.g. customvariable3 if you use call.peripheralvariable3)

How to send email using pl/sql containing the result set as the msg body

Hi.. im using Pl/SQL code to send emails to the users from a dataset that is obtained in a databse table. i have used utl_smtp commands to establish the connection with the smtp mail server. im stuck at the logic when i have to include the message body which is actually the result set of a table.. For instance
IF (p_message = 0) THEN
UTL_SMTP.write_data(l_mail_conn, 'There is no mismatch between the codes' || UTL_TCP.crlf);
ELSE
UTL_SMTP.write_data(l_mail_conn, 'The missing codes are ' || UTL_TCP.crlf);
for s in (select * from temp)
loop
UTL_SMTP.write_data(l_mail_conn, ' ' ||s || UTL_TCP.crlf);
end loop;
END IF;
UTL_SMTP.close_data(l_mail_conn);
UTL_SMTP.quit(l_mail_conn);
END;
***p_message is a prameter passed to this procedure..
Can i obtain the result in the form i have it in my table. which has three columns. I want to display the three columns as it is with teh records. ?

this is not related about this forum but you can use below,
CREATE OR REPLACE PROCEDURE SEND_MAIL (subject varchar2,mail_from varchar2, mail_to varchar2,mail_msg varchar2)
IS
mail_host varchar2(30):='XXXXX';
mail_conn utl_smtp.connection;
tz_offset number:=0;
str varchar2(32000);
BEGIN
begin
select to_number(replace(dbtimezone,':00'))/24 into tz_offset from dual;
exception
when others then
null;
end;
mail_conn:=utl_smtp.open_connection(mail_host, 25);
utl_smtp.helo(mail_conn,mail_host);
utl_smtp.mail(mail_conn,'[email protected]');
utl_smtp.rcpt(mail_conn,mail_to);
utl_smtp.open_data(mail_conn);
utl_smtp.write_data(mail_conn,'Date: '||to_char(sysdate-tz_offset,'dd mon yy hh24:mi:ss')||utl_tcp.crlf);
utl_smtp.write_data(mail_conn,'From: '|| mail_from ||utl_tcp.crlf);
utl_smtp.write_data(mail_conn,'To: "'|| mail_to ||'" <'||mail_to||'>'||utl_tcp.crlf);

utl_smtp.write_data(mail_conn,utl_tcp.crlf);
utl_smtp.write_data(mail_conn,replace_turkish_chars(mail_msg)||utl_tcp.crlf);
utl_smtp.write_data(mail_conn,utl_tcp.crlf);
utl_smtp.close_data(mail_conn);
utl_smtp.quit(mail_conn);

How to set a variable in portal session using web dynpro java.

Hi,
I have created a web dynpro application, which is running inside portal. I have created a role called "R1". Inside role R1, i have created 3 workset W1, W2 and W3. and inside each workset i have some pages and iviews.
My requirement is when user logins to the portal , and when he clicks on role R1 for the first time, a login page should come (so that we can do revalidation), and when he enters his password again in that login page , then only workset W1, W2 and W3 should be visible/accessible to him and after successful revalidation, if he clicks again on role R1, in that particular portal session, than that login page should not come.
for this, i thought i will set a variable in portal session, whenever user successfully revalidated himself, and if after successful revalidation he clicks again on role R1, i will check in doinit method of webdynpro whether variable is set or not (which i already set on successful revalidation), and if it is set then i will do Donavigation else i will present login page to the user.
Can anyone tells me how to set a variable in portal session using web dynpro java.
thanks

With session.setAttribute("name",object) you can store a Attribute in the session object.
with session.getAttribute("name") you can get it.
That's it.

JMS/AQ: Setting properties for JMS message using PL/SQL

I have created a procedure in PL/SQL that uses JMS messages, and now I need to include a property so that the subscriber can use a message selector to filter out unwanted messages. Is this possible using PL/SQL?
A previous post said: "... But you can have properties in the message payload itself and also define selectors on the message content ...". But I looked at Sun's tutorial and there it said: "A message selector cannot select messages on the basis of the content of the message body."
I have 300 different screens and messages apply only to one screen at a time. When the user is looking at screen 'A' I want him to only recieve messages that apply to screen 'A'. I thought I would do this with message selector, but is there any other way?
Here is my code(borrowed from an earlier post)
PROCEDURE ENQUEUE_JMS_MESSAGE AS
BEGIN
DECLARE
Enqueue_options DBMS_AQ.enqueue_options_t;
Message_properties DBMS_AQ.message_properties_t;
Message_handle RAW(16);
User_prop_array SYS.AQ$_JMS_USERPROPARRAY;
Agent SYS.AQ$_AGENT;
Header SYS.AQ$_JMS_HEADER;
Message SYS.AQ$_JMS_TEXT_MESSAGE;
Message_text VARCHAR2(100);
BEGIN
Agent := SYS.AQ$_AGENT('',NULL,0);
User_prop_array := SYS.AQ$_JMS_USERPROPARRAY();
Header := SYS.AQ$_JMS_HEADER( Agent, '', 'aq1', '', '', '', User_prop_array);
Message_text := 'Message 1 from PL/SQL';
Message := SYS.AQ$_JMS_TEXT_MESSAGE(Header, LENGTH(Message_text), Message_text, NULL);
DBMS_AQ.ENQUEUE(queue_name => 'tstopic',
Enqueue_options => enqueue_options,
Message_properties => message_properties,
Payload => message,
Msgid => message_handle);
END;
END;

Thanks for the answer. I managed to set the Correlation id and retrieve it using getJMSCorrelationID(). But I did not manage to use the MessageSelector on it. I have used the Topicbrowser which is not part of the JMS standard? I tried to enqueue the messages using Java too and tried to use the topicbrowser on both JMSCorrelationID and user defined properties withou success. Is there some special requirements of the TopicBrowser?
Enumeration messages;
oracle.jms.TopicBrowser browser =tsess.createBrowser(topic, "TS", "JMSCorrelationID = 'TST'");
int count = 0;
messages = browser.getEnumeration();
if(messages.hasMoreElements())
System.out.println("message"); //never executed
dtxtmsg = (TextMessage)(tsub1.receiveNoWait()) ; //returns a message
String corrID = dtxtmsg.getJMSCorrelationID(); //returns: TST
Thanks for your help so far...it would really save my day if you have some ideas on this too!

Declare, Set, and Use a variable in a SQL Developer Query

I come from the SQL Server world and am trying to do something very simple: Declare, set, and use a variable in a query. For example:
Declare @lastPeriod date;
Set @lastPeriod = (select max(payperiod) from table 1 where payperiod < current_date);
Select field 1,
Field2
From table2
Where payperiod = @lastPeriod
The variable is going to be used in more areas in the query which is why I am simply not using a Sub-query in the where clause. I appreciate any assistance.

This forum is for issues with the SQL Developer tool. You'd get more response in the SQL And PL/SQL forum.
That said, read up on bind variables and substitution variables.
Whenever you can you should use Bind variables (e.g. *:lastPeriod* ), as they increase performance. In sqldev, there's no need to declare as you will be prompted to enter them on execution (F9), but you do if you execute as script (F5) (e.g. VARIABLE lastPeriod VARCHAR2(30);).
Alternatively, Substitution variables (e.g. *&lastPeriod* ) will literally be substituted in your statement before the database parses it. In sqldev, there's no need to declare as you will be prompted to enter them on execution (either F9 or F5), but you can (DEF lastPeriod='TEST'; ).
Have fun,
K.
