How to use a variable global?

Oracle 10g Enterprise edition
Is there a way to retain a text in a global variable session specific?
The global variable is declared in a package specification. But i am losing the values as the session changes.
Can any one suggest me an approach to go with this?
Thanks

No you didn't do anything wrong.
Web applications are inherently stateless, so create a new session for each database request. Oracle's Application Express, which is a web based application, implements a form of state persistency through it's own means of storing values. It does this by allocating a session ID to the user as they start up their connection to the application and then that session ID is passed as part of the URL to each page call, which allows the Application Express "engine" on the database to identify the session and pull back any variables that require persistency.
Sounds like you need to implement something similar.

  • How to use the variables used in the message mapping

    Hi ,
    In the message mapping we can declare variables in the JAVA section , these variables could be used across the mapping .
    I have tried using it but I am unable to retrieve the values assigned to the variables in one UDF into the another UDF .
    Please guide me how to use the variables declared in the JAVA section in the message mapping .
    Thanks
    Anita Yadav

    Anita,
    I have worked on the Global variables and i found no issues. Make sure that the variable is declared in the Declaration Section and then initlaized in the Initialization section.
    If you declare a variable in the Declaration Section ,
    int i;
    then in any udf you can use if directly. No need to re declare  the variable in the UDF. If you do this, then it becomes a local variable.

    You cannot avoid hard parsing - as the 1st time a SQL statement (like the SELECT or DELETE statements in your code) is encountered, it does not reside in the server's Shared Pool, and needs to be added into the pool via a hard parse.
    Bind variables does not prevent hard parsing. Hard parsing happens when the SQL statement (with or without bind variables) is a brand new statement encountered by the server.
    Bind variables enables the same SQL cursor to be reused, by simply changing the bind variable value.
    Not using bind variables means that each SQL statement is unique and not shareable - as the value is hardcoded into the statement and cannot be changed via a bind value. This typically means LOTS of different SQL statements (where the only difference is the changed value in the statement) are created - with each statement being a new statement not seen before in the Shared Pool and needing to be hard parsed.
    One does not design one's code not to be hard parsed. There ALWAYS will be a hard parse in order to get a SQL statement into the Shared Pool. One designs one's code to REUSE cursors in the Shared Pool.

  • How to use shared variables?

    Hello..
            Can anybody please guide me in using shared variables... I'm learning LabVIEW 8.5.... But did not understand how to use shared variables... I tried to read web pages regarding shared variables but got confused.... So anyone can please help me...?
             Thanks for any help from you...

    You will have to give us the whole picture. What is your client computer; a PAC, desktop etc? What are you running on the client computer; a VI or an executable? Where are you going to deploy your library? On the host machine or the client machine?
    If I assume that you are running a VI on the client machine and are depolying the library on the host, all you have to do is to create another shared variable and bind it to the variable on the host machine. You can do this by checking the Bind to Source option when creating the variable and browsing to the network item in options. Be sure to have the library deployed on the host side before you attempt to do this otherwise you won't be able to find the variable.

  • How to use string variable onside quotes

    Hi,
    i would like to know how to use string variable onside quotes. what i mean is if i have a LOV variable P_STATUS as character string.
    and in my PL/SQL function i give a query as
    Q AS VARCHAR2(1000) := 'SELECT * FROM EMP
    WHERE STATUS = :P_STATUS';
    Is this correct. I Know that the above statement works when the LOV is an integer, but when i use a character LOV return value the above statement does not work. how can i get in the character LOV value.
    Can someone help me please.

    Yes I tried binding all the values separately. It is working, but, I am trying to pass all values by variableBut you can't. The variable is holding a single string value.... that is just 1 value. Your binding are expecting multiple values. You can't bind 1 string value and expect Oracle to magically know how to break your string up into seperate values for the bind variables. What if one of your bind variables actually needed e.g. a comma seperated string as it's value? How would Oracle know that?
    You must bind each thing seperately. That's the way cursors work.
    , because i have more than 150 tables in which data will be load. that's why i m trying to create a unique procedure to load data one by one table. Otherwise I have to write individual procedures for per procedures.It's a hard life being a software programmer, but somebody's got to do it. Unfortunately there are too many people who try and write "generic" procedures and expect them to just work. I mean why don't Oracle just implement some SQL command so you can do...
    execute immediate 'load all my tables';save us all the hassle eh!? ;)
    when i write all the columns like
    execute immediate (insert_string) using rc1.TOLL_ID, rc1.LANE_ID, rc1.RECEIVED_DATETIME, rc1.LANE_QUERY, c1.EXECUTED_DATETIME
    but it is not possible to generate runtime variable thats why I m trying to assign all values to a single variable and use it like
    execute immediate (insert_string) using (v_string)
    how can I separate the values and ho to use it .Don't use execute immediate. Use the DBMS_SQL package instead and bind your values dynamically with loops to cover all the columns you need etc.

  • How to make a variable global to use in all of my cfm page?

    I have a problem with the variables.
    i need to use a variable  " loginrecord" in all of my cfm pages, its created in my login.cfm and the value of this needed in other page and maybe i need to change it .
    in ASP simply we can use SESSION to make a variable global , is there any way in coldfusion ?
    also in ASP we have a command SESSION.SESSIONID ,  so return the unique number from browser and we can se it as a security check for each one of people login to our site and each one is seperate random and unique number , is there any similar in coldfusion ?
    Thanks
    Alireza

    Thanks,
    the reason at the moment i stock with this command is i need to have login information available in all the pages to check the security. the good point i had in ASP is SESSION.SESSIONID   , it make a unique number base on browser and i can check it if user loged in or no , or if loged in is the same user or other user . i couldnt find same command in coldfusion , and now i use <cflogin> but if i can find the way to have a browser session it help me in other part of my program.
    i start coldfusion new ( near a month ) i have some book and Lynda DVDs, also online sources , and in this priod i re developed one of my program from ASP to coldfusion and its work. i am happy of this and help me to develop better and faster . in compare the coldfusion developed one realy is 40% original development in size and 50% faster . i have good background of ASP in last 8 years include MCSD and developed many program for a small and big companies. but i wanna to continue with coldfusion because i found it more helpfull than ASP specialy in FLASH development .

  • How to use user variable in Member Formula

    Hi All
    I have to write a member formula for %linearity quarter for a weekly application.This member will be used in reports and we do not want to do this calculation in reports, hence need to write member formula. The formula is
    Week1 of Q1 forecast / Q1 Total Forecast , Week2 of Q1 Forecast/ Q1 Forecast.............,Week15 of Q2 forecast/ Q2Total Forecast.......and so on.
    According to me it should work in the below mentioned manner , but need help in improvising the formula.
    If(@ismbr("Weeks1") or @ismbr("Weeks2") or @ismbr("Weeks3") or @ismbr("Weeks4") or @ismbr("Weeks5") or @ismbr("Weeks6") or @ismbr("Weeks7") or @ismbr("Weeks8") or @ismbr("Weeks9") or @ismbr("Weeks10") or @ismbr("Weeks11") or @ismbr("Weeks12") or @ismbr("Weeks13") or @ismbr("Weeks14") )
    "Current_Forecast"/"Q1"->"Current_Forecast";......
    If anybody can help in suggesting how can i use user variable in this formula to achieve the required result.
    Thanks

    Hi
    Thanks for the suggestion and it would be a better idea to use ISIDESC as compared to ISMBR.
    I also wanted to ask if in the below mentioned formula if the result of first line is true than will the second line pick the current_forecast value of the respective member of Q1 and divide it by the current_forecast value of Q1.
    IF(@ISIDESC("Q1"))
    "Current_Forecast"/"Q1"->"Current_Forecast";
    Also i need to know how can i write a member formula for week YOY% using user variables.The general formula is
    Week 1 of FY13 - Week 1 of FY12/Weeks 1 of FY12
    Week 2 of FY13 - Week 2 of FY12/Weeks 2 of FY13 and so on till week 53.

  • How to use shared variables to address multiple Watlow controller​s on the same COM port

    Hello,
    I am trying to use LabVIEW 2010 to control 4 Watlow temperature controllers on one COM port. 3 are Model 96 and 1 is an EZ zone controller. Each controller has a unique modbus address, and I am trying to read from and write to individual registers (such as closed loop setpoint) using shared variables. I am getting return data when reading (although the data appears to be invalid), but am unable to change the value in the register by writing. How can I be sure that the Modbus server is sending commands to the correct controller?
    Chuck
    Solved!
    Go to Solution.

    Peter,
    Thanks for the reply. I have actually solved that problem. I realized that the Modbus server address has to be the same as the controller's Modbus address.
    I have, however, run into another problem. Perhaps you could help me with that. I have a system with 4 Watlow controllers, 3 are series 96 controllers, one is PID only and 2 are ramping. The 4th controller is an EZ zone. I am using RS485 for communications and the controllers are all wired in parallel for communications and power.
    I have set up 2 Modbus servers for 2 of the controllers.
    This is the first I have ever worked with Modbus based communications. I have successfully programmed using the Modbus read/write VIs, and am wanting to move to shared variables. My questions right now revolve around addressing, Modbus I/O servers and COM ports. Specifically, at this point, I know the addresses need to match up between the server and the slave device (Watlow controller in my case), how many servers can I create and use on one COM port? If the number is limited, is there a way I can specify an address that I want the server to talk to? Will the broadcast mode work to request data values from the controllers?
    I'd appreciate any information you can help me with, or if you could point me to some sort of concise 'How-To' for Modbus communication.
    Thanks.
