Dynamically Updating Tables

So what I'm trying to do is have either an external script or an APEX function:
1) Find information on all of the current tables in database (schema, table, columns) which isn't hard, at the moment I have a script .
More importantly I need a way to (preferably automatically, maybe once a day, but manually is fine too)
2) update a table with that information
Is there a way to do this with PL/SQL? That would be ideal, but running an external script works. Looking around, the REST API might work? But I wasn't sure how or if it works for this.
Thanks!

Welcome to the forum: please read the FAQ and forum sticky threads (if you haven't done so already), and ensure you have updated with your profile with a real handle instead of "878859".
You'll get a faster, more effective response to your questions by including as much relevant information as possible upfront. This should usually include:
<li>Full APEX version
<li>Full DB version and edition
<li>Web server architecture (EPG, OHS or APEX listener)
<li>Browser(s)/version(s) used
<li>Theme
<li>Templates
<li>Region type

Dynamic update of cursor records when table gets updated

Hi,
I am having a table with 4 columns as mentioned below
For a particular prod the value greater less than 5 should be rounded to 5 and value greater than 5 should be rounded to 10. And the rounded quantity should be adjusted with in a product starting with orderby of rank with in a prod else leave it
Table1
Col1     prod     value1     rank
1     A     2     1
2     A     6     2
3     A     5     3

I have taken all the records in to a cursor. Once after rounding the request of 1st rank and adjusting the values of next rank is done. Trying to round the value for 2nd rank as done for 1st rank. Its not taking the recently updated value(i,e adjusted value in rounding of 1st rank).
This is becoz of using a cursor having a value which is of old value.
Is there any way to handle such scenario's where cursor records gets dynamically updated when a table record is updated.
Any help really appreciated.
Thanks in Advance

Hi,
Below is the scenario. Which I am looking for.
ITEM_ID(A)
ITEM_ID Value Date
A          3     D1
A          5     D2
A          3     D3
A          5     D4
A          3     D5
A          5     D6
Rounding for Item A has to be done for the rows less then D2 and rounding value is
x and value adjustment to be done from very next row.
--For record D1 rounding to be done and value adjustment is to be done from D2 to till the end untill the adjustment value is 0.
--For record D2 (updated value has to be taken from rounding which updated in D1 row rounding) and the adjustment has to be done from very next row D3 to till the end or adjustment value is o.
--For D3 row onwards no rounding has to be done.
ITEM_ID(B)
B          7     D1
B          8     D2
B          9     D3
B          5     D4
B          4     D5
B          3     D6
Rounding for Item has to be done for the rows less then D3 and rounding value is
y and value adjustment to be done from very next row.
--For record D1 rounding to be done and value adjustment is to be done from D2 to till the end untill the adjustment value is 0.
--For record D2 (updated value has to be taken from rounding which updated in D1 row rounding) and the adjustment has to be done from very next row D3 to till the end or adjustment value is o.
--For record D3 (updated value has to be taken from rounding which updated in D2 row rounding) and the adjustment has to be done from very next row D4 to till the end or adjustment value is o.
--For D4 row onwards no rounding has to be done.

TSQL - Dynamic Query Case statment update issue - to update table by left shifting the rows

Hi all
I need an help on my tsql query in 2000 to fix the case statement.
I have a table like shown below.
On this table where ever I see PortID as 101 and 105 I need to remove it and shift the rows from right to left.
ie on First row PortID1 is 101 so I need to remove it and replace it with PortId2 and similarly PortID2 replaced my PortID3 and so on.
ie like on excel if you delete cell we need to shift the rows to left .
I wrote an dynamic update statement i,m not sure on the assigning dynamic case statment.

Dynamic update of column with values derived by formula on other table.

i have 3 tables; table A,B and C
table A has two columns (id and Quantity), based on the id value, the quantity value is computed using a formula on two rows (one from table B and the other from C).
the formula is different for each id value.
but after every month the quantity value has to be updated (because tables B & C get updated monthly).
example. given id=1, quantity= select round((sum(h.col1)/sum(p.col1), 2) from B p, C h
given id=2, quantity=select round((sum(col1)/sum(col3)), 2) from C
so for every id the quantity is derived by a different formula, but the quantity value has to be recomputed every month.
need help.

1. update table a
quantity = decode (id,1, <formul1>, id,2 , formula 2...)
2. if you wanto schedule this as monthly task
use dbms_job.submit
send the above query to "What" parameter.

Problem with dynamic internal table updation

Hello Folks,
I created a dynamic internal table

        OTHERS                    = 2.
ASSIGN i_dyntab->* TO <f_dyntable>.
and created a work area
CREATE DATA wg_f_split LIKE LINE OF <f_dyntable>.
    ASSIGN wg_f_split->* TO <f_wg_dyntable>.
My requirement is that , i have to loop a normal internal table and append those records to the filed symbol internal table.
READ TABLE i_normal_itab INTO wg_split INDEX wl_rows-index.
      IF sy-subrc EQ 0.
        ASSIGN wg_split to <f_wg_dyntable>.
         APPEND <f_wg_dyntable> to <f_dyntable>.
       endif.
here i am geeting dump as "MOVE src TO dst" ... i can get the data in the work area FSymbol but cannot append it in Internal table Field Symbol.. Please help..

Hello Sandra,
Thanks for the reply..
First i tried appending the normal work area to the fieldsymbol internal table.
append wg_split to <f_dyntable>
This is hiting dump the same dump and so i created a fieldsymbol work area. ( <f_wg_dyntable>.)and tried to append the field symbol internal table with this work area. which is again giving the dump
APPEND <f_wg_dyntable> to <f_dyntable>. ( Again a Dump)

Updating Table Columns Dynamically

Hi Everybody,

Kindly let me have your solutions.
Thanks in advance,
MAK

This approach can be dangerous. You are currently trying to update all columns in the tables to null if any of the columns are 'N/A'. Your query does not exclude external tables which may not be updatable. Your other query does not exclude data types that can not include 'N/A' such as number. You might want to move your commit outside the loop as you may end up committing partial updates.
You might try to capture the SQL that you are generating;
create table t(col2 varchar2(4000));Then in your package;
insert into t values(v_sql_stmt);
-- EXECUTE IMMEDIATE v_sql_stmt;

Kindly help me to solve this.
With Thanks,

please provide more info about the dump to try to help you
as max said, it could be because the field symbol is not global and if its global maybe you are not refering well to the column
i assume that you are using "ASSIGN COMPONENT comp OF STRUCTURE struc TO <fs>" to capture the value changed
validate always the sy-subrc after the assignment.
but the check changed data have parameters that have the old and new values
please provide more info...

Dynamically Updating Content Server Portlets

[urlHi, I am currently having difficulty dynamically updating content server portlets. I have a portlet of the following form:[/url]
ArticleName Author Title Date mystory author1 title1 04/05/01
story2 author2 title2 06/07/04
story author3 title3 01/02/03
So I have this table where each one of the line items is an article in the content server. So, for example the first line item is an article "mystory" by "author1", with title "title1" and date "04/05/01" additionally there is an article text field, but this isn't displayed unless I click on the article name.
I can set up the basics of this portlet, but when I try to add any real functionality I run into one of two problems.
First Problem: Passing Information
I cannot find a way to pass information between content portlets. For instance, if the user would like to "re-sort" this table based on "date", I would like to have the user click on the "date" column heading and then reload the page. To do so, I would have to pass the section name back to the page so that it could resort based on this data. I have not found anyway to effectively pass information to a content server portlet. I am building these pages through use of the presentation template framework (so I can have access to the content items) but that seems to change the way portlets are handled.
I got around this limitation with a regular portlet by creating an intermediary page which captures passed information and stores it to the session state. Once the information was in the session state, it is accessible to the portlet on the first page. However, this only works because remote portlets do not change their session id once loaded. Content Server portlets, on the other hand, change their session id after every reload of the browser or page change. I can send information from a content server portlet to an intermediary page, but I cannot send it back to the portlet because the session id has changed so I have no idea of knowing where to send the information. I can write it to a session state, but by the time I return to the portal page, the content server has changed its session id so it does not know where to look any longer.
I suppose it would be possible to create an application state variable and append it with some static token (if there is some static variable per portal session) but I would rather not have to deal with application variables if at all possible.
Second Problem: Dynamically Updating PCS Tags
Even if I were able to the pass information back to my content server portlet, I run into another issue. The easiest way to sort content server items is using the filter command in the pcs:foreach tag. So, if I wanted to sort by author name, I could do something like the following <pcs:foreach var="item" expr="filter(folderByName('content'), filtered.name == '"name")" or something like that (the syntax may be incorrect, I just wrote this off the top of my head). However, it appears that the way the presentation templates are compiled goes in the order of PCS tags THEN JSP. So I would have no way of dynamically changing the variable on which I sort. For example, if I clicked on "Date" above in my table, I would like to be able to dynamically change my code so that I sort on date, and not name. I cannot find a solution to this problem.
My workaround is to use the pcs tags to write out all the possible sortings to java array objects. This gives me access to the data on a JSP level and based on whatever the user will chose, I could then display that array. While this works, it is extremely ghetto and inefficient. Any help or suggestions would be fantastic.
Thanks a lot,
Jason Grauel

You can use just about any javascript you want in any Content Server presentation template including ones that are used for portlets.
However, you should be careful to name javascript functions and global variables uniquely so that they do not conflict with any other javascript on the page. To do this, you can append the item id to function and variable names, for example,
function doSomething<pcs:value expr="pcs_id"></pcs:value>() {
return true;

To create a deep structure for dynamic internal table.

Hello
My ALV has fields which are defined dynamically during execution.
so, i did it in the following way,
Declared Field symbolds, DREF and fieldcatalog as,
FIELD-SYMBOLS: <t_dyntable> TYPE STANDARD TABLE,
              <fs_dyntable>.
DATA:   dref_dyntab    TYPE REF TO data,
        dref_dynwa     TYPE REF TO data.
DATA: ts_fieldcatalog TYPE lvc_t_fcat.
DATA: wa_fieldcatalog TYPE lvc_s_fcat.
Updated Fieldcatalog dynamically as,
*function module to read segment structure
    CALL FUNCTION 'SEGMENT_READ'
      EXPORTING
        segmenttyp           = v_segment_name
      TABLES
        segmentstructure     = ts_seg_structure
      EXCEPTIONS
        no_authority         = 1
        segment_not_existing = 2
        OTHERS               = 3.
    IF sy-subrc <> 0.
      CASE sy-subrc.
        WHEN '1'.
          MESSAGE e024.
          STOP.
        WHEN '2'.
          MESSAGE e025 WITH v_segment_name.
          STOP.
        WHEN OTHERS.
          MESSAGE e023.
      ENDCASE.
    ENDIF.
*FETCH FIELDS FROM STRUCTURE OF SEGMENT AND CREATE FIELDCATALOG FOR
EACH FIELD OF SEGMENT (DYNAMIC FIELD CATALOG)
    LOOP AT ts_seg_structure INTO wa_seg_structure.
      ADD 1 TO v_counter.
      wa_fieldcatalog-fieldname = wa_seg_structure-fieldname.
      wa_fieldcatalog-col_pos   = v_counter.
      wa_fieldcatalog-ref_table = wa_seg_structure-segtyp.
      APPEND wa_fieldcatalog TO ts_fieldcatalog.
      CLEAR wa_fieldcatalog.
    ENDLOOP.
and generated dynamic internal table using fieldcatalog as,
*--Method to get the structure of table using fieldcatalog.
CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
      it_fieldcatalog = ts_fieldcatalog
    IMPORTING
*--Variable of type REF TO DATA.
      ep_table        = dref_dyntab.
IF sy-subrc <> 0.
    MESSAGE e023.
ENDIF.
*--Dynamic internal tables required when show segments selected
IF p_selseg IS NOT INITIAL.
    ASSIGN dref_dyntab->* TO <t_dyntable>.
*--Create dynamic work area and assign to FS
CREATE DATA dref_dynwa LIKE LINE OF <t_dyntable>.
    ASSIGN dref_dynwa->* TO <fs_dyntable>.
And then i populated this <t_dyntable> which is being passed as data-table to method
CL_GUI_ALV_GRID => SET_TABLE_FOR_FIRST_DISPLAY
for ALV grid Display along with above used filedcatalog ts_fieldcatalog.
Things are fine till here, but now i have the requirement to edit selected rows of the ALV display..
As you might be aware, we need a field
        TS_STYLEROW TYPE lvc_t_styl, (i.e, a field of type 'h' and we can say as an internal table inside an internal table or else as a deep structure)
in the output internal table <t_dyntable> to meet our requirement.
My issue is about declaring one such field of type 'h' in this dynamically created internal table ''<t_dyntable>".
I tried in the following way by adding one such field to fieldcatalog :
*Field for Styling
ADD 1 TO v_counter.
wa_fieldcatalog-fieldname   = 'TS_STYLEROW'.
wa_fieldcatalog-tabname     = 'TS_STYLE'.
wa_fieldcatalog-col_pos     = v_counter.
wa_fieldcatalog-no_out      = 'X'.
wa_fieldcatalog-inttype     = 'h'.      " I even mentioned this
APPEND wa_fieldcatalog TO ts_fieldcatalog.
CLEAR wa_fieldcatalog.
But this is creating a field of type 'C' in the table <t_dyntable> instead of what i was expecting
Guyz and respected,
Please advice me with the solution or ur ideas....
Note : The overall requirement is create a deep structure for dynamically generated internal table.
Your help is highly appreciated and unforgettable..!!!!!!!

Dynamic UPDATE statement with parameters for column names.

Hello,
On this* website I read "The SQL string can contain placeholders for bind arguments, but bind values cannot be used to pass in the names of schema objects (table or column names). You may pass in numeric, date, and string expressions, but not a BOOLEAN or NULL literal value"
On the other hand, in this Re: execute immediate with dynamic column name update and many other
posts people use EXECUTE IMMEDIATE to create a dynamic UPDATE statement.
dynSQL:='UPDATE CO_STAT2 CO SET CO.'||P_ENT_B_G_NAME||' = '||P_ENT_E_G_WE||'
WHERE ST IN
(SELECT ST FROM STG_CO_STAT2_TEST CO WHERE
'||P_ST||' = CO.ST AND
CO.'||P_ENT_E_G_NAME||' > '||P_ENT_E_G_WE||' AND
CO.'||P_ENT_B_G_NAME||' < '||P_ENT_E_G_WE||');';
EXECUTE IMMEDIATE dynSQL ;
Since this statement is part of a Stored Procedure, I wont see the exact error but just get a ORA-06512.
The compiling works fine and I use Oracle 11g.
http://psoug.org/definition/EXECUTE_IMMEDIATE.htm

OK I extracted from all of your posts so far that I have to use "bind-variables with :"
From all the other tuorials and forums posts, I assume using the pipe is correct so I added those as well into the script:
set serveroutput on format wraped;
DECLARE
dynSQL VARCHAR2(5000);
P_ENT_E_G_NAME VARCHAR2 (100) :='test1'; P_ENT_E_G_WE VARCHAR2 (100) :='01.02.2012'; P_ENT_B_G_NAME VARCHAR2 (100) :='01.01.2012';
P_ST                VARCHAR2 (100) :='32132';
BEGIN
dynSQL:= 'UPDATE CO_STAT2 CO SET CO.'||:P_ENT_B_G_NAME||' = '||:P_ENT_E_G_WE||'
              WHERE ST IN (SELECT ST FROM STG_CO_STAT2_TEST CO WHERE
              '||:P_ST||'                           = CO.ST                  AND
              CO.'||:P_ENT_E_G_NAME||'     > '||:P_ENT_E_G_WE||' AND
              CO.'||:P_ENT_B_G_NAME||'
< '||:P_ENT_E_G_WE||')';
--this is somehow missing after the last < '||:P_ENT_E_G_WE||')';
dbms_output.enable;
dbms_output.put(dynSQL);
--EXECUTE IMMEDIATE dynSQL;
END;Problem:I think I figured it out, the dates that I parse into the query need additional '

Dynamic Update in real time with slider control

We have requirements to display complex data in a graphical format. So far this has gone well by leveraging ADF and DVT components (dvt:Map, dvt:gauge, dvt:bargraph, af:tables, af:inputNumberSlider, etc.); however, we recently have been asked to add real-time animation of these controls over time. In brief, the user requires the ability to control the on-screen visualization of data by sliding the control on an af:inputNumberSlider (or equivalent) that represents a multi-month time scale. While sliding this control, the user expects to see the data visualization controls dynamically update in real time, keeping up with the rate at which the user moves the slider control. Think of this like a flip book animation where the slider controls the page the user is looking at and they can flip through the pages forwards or backwards at any desired speed. The time slider increments are one hour.
Our current application architecture:
Oracle ADF Fusion Web Application (v 11.1.1.5)
EJB 3.0
Eclipselink
Oracle 11g
Any kind of help is highly appreciated.
Thanks,
Mehabub

Hi,
the af:inputNumberSlider does not provide this functionality. Your alternative is a custom component (or any component that raises a client JS event) and call an af:serverListener in a custom event to send the notification to the server.

Dynamic update of text from JTree manipulation

Hi I working on an application that uses both a JTree and text view at the same time.
What I want to do is everytime a node is added/edited/removed from the JTree the text for that node is dynamically updated in the tree view.
At the moment what I do is everytime something is edited in the JTree the whole text is re-written. This is causing the program to slow down for large files.
What I have thought of doing is producing the text for only the edited node, however this may affect others node, for example if a child node is added the parent node needs a closing tag.
Is there anyway I could possibly do this?
An alternative I had thought of was, because it is the syntax highlighting that is taking the time. I thought I could produce the full text for the edited tree then compare it to the pre-editted text. Then only sytax highlight the difference and add it to the text view. Would this be possible?
Cheers Alex

Just enter the rate and the square footage; do the
calculation when you
pull the data from the database. In general, you don't want
information stored in a database which depends on other
information (ie
calculated fields). The prime example is calculating an age
when you
get Date of Birth information.
