How to dynamicly create a field name AND access it

All,
I am trying to build a code block that will access what amounts to a table structure inside a table. I have 38 occurances if a set of 3 fields. (Source system had an internal array/occurs clause that was converted for our ODS into individual fields) I am returning a single row as a row type and have addressability to all fields. What I am trying to avoid is coding my logic block 38 times, 1 for each occurance.
FOR X IN 1 .. 38 LOOP
V_CAT_CD_X := 'CAT_'||X||'_CD';
End Loop;
The following is the display of the correctly built field:
--> Loop Cat CD: CAT_1_CD Rec count:1 Loop counter:1
--> Loop Cat CD: CAT_2_CD Rec count:1 Loop counter:2
--> Loop Cat CD: CAT_3_CD Rec count:1 Loop counter:3
--> Loop Cat CD: CAT_4_CD Rec count:1 Loop counter:4
My problem is that my row cursor PP1 is addressable hardcoding PP1.CAT_1_CD or PP1.CAT_2_CD ect, however I am having problems using my created string to access the field.
What do I need to do to gain accessability via this method?
I do have the ability to select the column names from the system tables but even then, I am lacking addressability to my ROW type using the selected field name.
Thanks
Greg

  • How can I create a new name and itunes acct

    I want to give my old 2nd generation ipod nano to my son.  Can I create a new device name and itunes for the ipod?

    Yes.  I would suggest creating a separate user account for him on your PC to use to store his own separate iTunes library.  See Method 1 from this Apple support document for more information and assistance.
    How to use multiple iPods, iPads, or iPhones with one computer
    When he connects the iPod to this new iTunes library he'll need to Erase and Sync (or restore) the iPod allowing him to set it up as his own iPod and everything just as if you had just taken it out of the box.

  • How to dynamically define a file name and its path in a web application

    Hi, I want to create a simple web application that reads from an XML file and displays the data back to the user. The xml file is created independent of my application on the same machine that the Application Server runs. How can I define my xml file name and/or path to be independent of my code and not hard-coded in my application?

    By an external configurationfile? That can be a propertiesfile, a xml file, an ini file, a plain vanilla txt file, etcetera.

  • How to dynamically populate a manager name and level for any user who login

    Hi All,
    I need some help in doing this in my DB:
    Table 1 is the the manager hierarchy {which basically shows the structure of every employee's org).
    Table 2 is a list of all people manager ( all these usernames will also be in table 1). What i need to find is using the username from Table 2, the highest level that username exists in the manager hierarchy.
    For ex:
    Table 1: { What this shows is Sam is CEO and Jeff reports to him. So for Sam, he will exist on all 15 levels and Jeff will have Sam has his top level manager and then Jeff will repeat for all remaining levels till 15.
    Manager Level 0  Level 1  Level 2 Level 3...Level15
    Sam                       Sam     Sam     Sam         Sam
    Sam                        Jeff     Jeff        Jeff          Jeff
    Now in Table 2:
    User Name   Manager Level/Name
    Sam               Manager Level 0 Sam
    Jeff                 Manager Level 1 Jeff
    As you see, for each user name in Table i want to populate their high level from the manager hierarchy {their record in manager hierarchy).
    Hope This helps to clear the confusion.

  • Dynamic form... field names and values...

    Boy-Howdy. I wish I had the opportunity to stop by this forum and hang out at a time when I am not having issue, but, alas... I appreciate the brain power of the great minds that populate this forum.
    I have an issue: I think I am close on this but cannot identify where my syntax is going awry. Here is a simplified edition of my situation.
    I have a form with a set of dropdown menus that filter a recordset. The group of drop downs are dynamic from a database and will vary depending on what category of products a visitor is viewing.
    If I browse to FRUIT: I get three options that let me filter for:
    Fruit Type
    - Apples
    - Bananas
    - Pears
    Fruit Grown By:
    - Organic
    - Any
    Fruit From:
    - Domestic
    - South America
    - European
    However, if I browse to LUMBER I get:
    Wood Type:
    - Pine
    - Walnut
    - Oak
    Wood Prep:
    - Pre Cut
    - RAW Timber
    Wood Origin:
    - North America
    - South America
    - Europe
    I have the variable naming and database values worked out. My only issue is when I browse to friuit and select apples I want apples to remain selected as I page through results.
    So, the dropdown field names are dynamic. Currently set to zgen1, zgen2, zgen3. I set a variable named sr and increment it to build the progressive 1,2,3 after the field name zgen.
    <cfparam name="sr" default="1">
    <cfoutput group="ft_id" query="oompa2">
    <strong>#f_ftrname#:</strong><br>
    <select name="zgen#variables.sr#">
    <OPTION value="">select...</OPTION>
    <cfoutput>
    <OPTION value="#ft_id#_#fs_id#">#ft_options#</OPTION>
    </cfoutput>
    </select>
    <br><br>
    <cfset sr=#sr# + 1>
    </cfoutput>
    But when zgen1 has a value (in this case "Apples") I can't figure out how to dynamically test for the presence of a value for each dropdown. I have dynamically created the field names (cfset xvalue="FORM.zgen#variables.sr#") to test against. However this creates a value of FORM.zgen1, FORM.zgen2, FORM.zgen3 as it loops when I want it to be Apples, Organic, Domestic.
    Example:
    The code:
    <OPTION value="#ft_id#_#fs_id#"<cfif xvalue IS "#ft_id#_#fs_id#"> SELECTED</cfif>>#ft_options#</OPTION>
    which is translating to:
    <OPTION value="15_5"<cfif FORM.zgen1 IS "15_5"> SELECTED</cfif>>Apples</OPTION>
    When I want it to be:
    <OPTION value="15_5"<cfif 15_5 IS "15_5"> SELECTED</cfif>>Apples</OPTION>
    I hope I am making sense. I would greatly appreciate it if someone could help me noodle this. I have a feeling it is not as complicated as my mind is trying to make it. Thoughts?

    Three selects related type code was not the way to go - because I need each filter to be independent. I created a custom tag that argues the state for each separately up to ten filters.

  • HR - dynamic selections field name and field value in the program

    HI all,
       I am using dynamic selections for a HR report.
    I have created a view with 20 fields and added it to HR report category ___00003(All fields suppressed).
    I need to check these fields in the program. But i am not able to get the field name and value in the program for dynamic selections fields.
    Please let me know how to get the field names and values in the program for dynamic selections .
    Thanks,
    Kranthi.

    You have to read the itab <i>pnpdynse</i> in your Program to obtain the Dynamic Selection values. This itab has a deep structure.. you can set a break point in one of the events before <b>get pernr</b> & in the debug mode, you will able to display the itab <i>pnpdynse</i>.. you can then identify how to get the values into your code..

  • How to get the co-ordinates of a dynamically created input field

    Hi,
    There is no provision in WD for getting screen coordinates and then placing the UI element.
    You to add the UI element to layout editor and based on the layout type it will add the UI element to respective position.
    I would advice not to create dynamic UI elements( instead you can create them statically and then play with visibility status through context binding ). This will be more effective way and less error prone. This is also recommended practice.
    still,For dynamic creation you can refer to following wiki:

  • HT1386 How do I create one Apple ID and iTunes user name and password for all of my Apple products: iPad, iPhone, and iPod plus iTunes on my PC?

    How do I create one Apple ID and iTunes user name and password for all of my Apple products: iPad, iPhone, and iPod plus iTunes on my PC?

    Yes, I do have multiple devices and it appeared to me that every time I tried to sync or log onto iTunes, the password was incorrect.  Consequently, I was and am constantly changing it.  Wouldn't it be nice if Apple would simply say that you only need one Apple ID and one password regardless of the number of Apple devices you intend to sync via iTunes. 
    Barring the above, how about a way to merge all of the Apple IDs and passwords into one.

    if you know the transaction code you use to post the uploaded data in SAP, you just need to do BDC recording in using transation SM35. Record the whole process and create a program from the recording... and you wont even need to know the tables and field names-- almost everything will be done for you....
    All you need to do is replace record data with upload data.
    You can also try to look for a standard Function Module / BAPI which can do the processing for you and provide it with a table containing the upload data ...

  • How set dynamically created query in GridControl?

    How set dynamically created query in GridControl?
    Thank you

    If your dynamic query is based on an Entity object, then you can probably use RowSetInfo setQueryInfo method.
    The argument to this method is a 'Query' object. There are three flavours provided in the oracle.dacf.dataset
    package.
    oracle.dacf.dataset.QueryViewInfo
    defines an updateable SQL query based on a predefined BC4J View Object.
    oracle.dacf.dataset.QueryStatementInfo
    Creates a view object based on an arbitrary SQL statement.
    oracle.dacf.dataset.QueryInfo
    Creates a View Object from an Entity Object and additional SQL clauses. The View Object will have
    that Entity Object as its sole Entity Object base.
    If in your application you are able to specify the name of the entity, then you can use the QueryInfo method to define your
    query. Please try the following.
    SessionInfo si = ....
    void runDynamicQuery()
    RowSetInfo rsi = new RowSetInfo();
    AttributeInfo ai = new AttibuteInfo(..);
    ai.setName(..);
    rsi..addChild(ai);
    si.addChild( rsi)
    rsi.setQueryInfo( new QueryInfo( ...../* include entity name */ .... ));
    rsi.setName(....);
    rsi.open(true);
    grid.setDataItemName(...);
    Hope this helps,

  • How do I create a Skype Name in this new environme...

    For a variety of reasons, I have created a new Microsoft Account. In attempting to set it up with Skype, I was never asked to create a Skype Name. This has created issues sining into Skype, as well as telling people how to Skype me. I do NOT want to give them my email address as my Skype contact. A Skype name is much more suited for this situation.
    How do I create a Skype name that people can use to call me?
    This beggs the question of why Loging into Skype and idnetification is co complicated. Associated with this one account there are the following methods of primary identification: Skype Name, Microsoft Account, Display Name, Skype Community Name, and there seems to be an additional display name for each Skype accont in the Community which begins with live: and then a modified form of the user's email address. That is A LOT to remember. I had a difficult time just logging in because it asks for my Skype name and the blank would not accept any of the aforementioned identifications. I had to get here by signing into Skype Desktop and then clicking a link to go through rather than signing in. The sign in would not accept my credentials.
    Bottom line is all these issues would go away if I could figure out how to get a skype name.
