Select type of columns in tables

HI all
I want to write a code which selects only "int" type of columns of all tables in database. How can I write it?
I want to know which column in which tables on my database is int type.
Thanks you very much...

Hi,
Even if you can create an int column, is not a known type column in oracle dictionnary.
You can search number column :
1* create table tit (titvcol int)
SQL> /
Table created.
1 select table_name, column_name, data_type
2 from user_tab_columns
3 where table_name = 'TIT'
SQL> /
TABLE_NAME COLUMN_NAME
DATA_TYPE
TIT TITVCOL
NUMBER
SQL> Also, to have all int type column, run the following query :
select owner,table_name, column_name
from dba_tab_columns
where data_type = 'NUMBER';Nicolas.

Not setting selected value in column of table control

Hi,
I have MATNR field in table control.
In PAI code is as follow.
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.
MODULE VALIDATE.
LOOP WITH CONTROL TC_FORMV.
FIELD /SISLEMCU/CNVADTL-MATNR SELECT *
                      FROM /SISLEMCU/CNVA01

When i take the help in MATNR column the above query works fine but when i select the entry from help MATNR is not gets set in column in table control.
Plz help me regarding this.
Thankx in adv.

When you select a value, PBO as well as PAI gets triggered. When PAI gets triggered, your query gets executed which gives sy-subrc <> 0 and due to this it might not filling the data selected..

How to display .doc/.xls file uploaded using blob type of column in table.

Hi,
Here
http://www.oracle.com/technology/obe/apex/apex31nf/apex31blob.htm
I learnt about uploading & viewing file through BLOB in a form or report . It works fine for pictures & notepad file. But when i upload word file (i.e. *.doc) or excel file ( *.xls ) , and try to view it through DOWNLOAD
it gives message box
' Do you want to save this file, or find program online to open it?'
I searched lot but enable to find proper & easy to understand solution.
Hope understand my problem.
Thanks in advance.

Hi,
I am using table emp having fields id,name,,,,,,,,,photo,mimetype,filename,last_update_date.
photo is of type BLOB. I updated photo (text item) on form.
I Used BLOB DOWNLOAD Format Mask with appropriate entries & selected display as Attachment.
So my problem is partially solved. Now if DOWNLOAD link on Form is clicked it displays Excel sheet
in different window. But still, DOWNLOAD link on my Interactive report not working properly.
DOWLOAD on interactive if it is clicked it has two problems
1) It opens image or notepad file in same window.
2) Not able to open Excel sheet.
thanks for reply.

How to select rows or columns of tables without using the mouse?

2nd post ever! Yeah! \m/
In Excel, I can select entire rows or columns of data WITHIN TABLES--i.e., not selecting entire sheet rows or columns--by going to any cell on the perimeter of the table, holding down shift+ctrl, and clicking a direction arrow. So for example, if I have a table in columns D-G and rows 1-5, I can highlight row 4 by going to the first or last cell of that row, holding down the shift+ctrl, and hitting the appropriate direction arrow. You might think this is superfluous given that you can use the mouse to select cells. But that becomes cumbersome with large tables, and this method can be more efficient even with small tables.
Similarly, it's often useful to navigate tables, particularly large ones, by moving from any cell within the table to the end or beginning of that row or column by holding down ctrl and hitting the appropriate arrow key. In Excel, this ctrl+arrow key method also allows you to skip blank cells, which is another very useful navigational feature.
I tried numerous combos involving shift, ctrl, command, alt/option and the arrow keys. Haven't found a way to do any of this yet.
Anyone?

Hi Josh,
Numbers is organized differently than Excel, and the navigation tools are different too. Many of us miss our particular favorites from spreadsheets past, but this is Numbers, not a clone. The biggest adjustment is to go from huge monolithic sheet-tables containing virtual sub-tables to a simple blank sheet with small tables, sometimes many per sheet. Navigating is no big deal in these small tables and neither is getting from one small table to another, using the Sheets pane.
Selecting a particular Table is as easy as clicking on the table's name in the Sheets pane. Selecting a particular row, or column, or ranges of rows or columns is done by clicking on the table's row and column labels, left side and top side once a cell is selected in the table.
Numbers is weak at handling large Tables and documents that are large overall. We know this and many of us still prefer it to the alternative when the tool fits the task.

Drop down selection for a column in Table Control

Hello,
I have a table control where data is displayed. The user can fill data in one of the column and save. We want to have a drop down in that column where user can select a value. This column is a qunatity field.
Please guide how it can be done.
RR

In SE51 screen editor, double-click on the editable field and set the dropdown listbox at listbox. As I don't think that you have domain value or table value for this field, set the field value list to "A" from program.
Then in the PBO use the FM VRM_SET_VALUES to fill the list of allowed values. do this in a module called in the LOOP AT WITH CONTROL which fills the table control from the program data. (use a name like TC_XXXX_CHANGE_FIELD_ATTR)
I'm not sure SE51 will allow you to use a quantity field in a listbox, so use a character field (check also right justified box on dynpro field attrinutes window), in VRM_SET_VALIUES parameters and in initial filling of the screen field use a WRITE xx UNIT yy to fill the screen field. Then a MOVE should perfect correctly when filling actual database/abap field by a move statement.

You will need to create two new TYPEs. One that has all of the columns of the TOSS.SEEKER table and the new SCORE column and then a TYPE that is a table of the first type.
See the Example 12-22 Using a Pipelined Table Function For a Transformation in the PL/SQl language reference
http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/tuning.htm#i53120
Here is the first part
-- Define the ref cursor types and function
CREATE OR REPLACE PACKAGE refcur_pkg IS
TYPE refcur_t IS REF CURSOR RETURN employees%ROWTYPE;
TYPE outrec_typ IS RECORD (
    var_num    NUMBER(6),

    var_char2 VARCHAR2(30));

BEGINModify
TYPE outrec_typ IS RECORD (
    var_num    NUMBER(6),
    var_char1 VARCHAR2(30),
    var_char2 VARCHAR2(30));
TYPE outrecset IS TABLE OF outrec_typ;to include all of the columns you need. Unfortunately you will have to manually list all of the columns of the TOSS.SEEKER table. If you expect to need this same structure in other places you should create them as SQL types instead of PL/SQL types.
This example should be enough to show you how to change your code to do something similar.

Database Adapter: cannot access table with complex record type as columns

Hi all,
I cannot perform any operations on a table that has columns with complex record type.
I have created a table to store purchase order details.
Sample script:
CREATE type XX_CUST_INFO_TYP as object
ssn VARCHAR2(20),
rating NUMBER(15)
CREATE type XX_ITEM_TYP as object
item_name VARCHAR2(20),
unit_price NUMBER(15),
quantity NUMBER(15)
CREATE table XX_PORDER (cust XX_CUST_INFO_TYP, porder XX_ITEM_TYP);
When i try to access the table X_PORDER in jdev through a database Adapter, i receive the error as
"some tables contains columns that are not recognized by the database adpter"
1.) so in this case, how to include such tables that have complex types?
Also, check out this scenario also..
1. add a table through a database adapter
2. drop the table in backend
3. i can still see the table and its structure in the database adapter wizard even after restarting Jdeveloper.. How is it possible?
These are some really interesting scenarios to experiment. Please suggest your ideas on this..
Thanks All!

Hi Hem,
for a select you could select against a view. And for inserts you could create a stored procedure. They support complex types since 10.1.2. Complex types support in tables/views was added for 11 (next major release).
You might be able to use PureSQL as a workaround too, i.e.
insert into XX_PORDER values (XX_CUST_INFO_TYP(?,?), XX_ITEM_TYP(?, ?, ?))
As for your other problem, in 10.1.2/10.1.3 the DBAdapter wizard sits on top of the Jdev Offline Tables and TopLink Mapping Workbench components. When you remove a table in the wizard it won't delete the Offline DB component. It was added by the wizard, but afterwards it is public to the entire Jdev project. You must remove it from Jdev yourself. This has been improved for the next major release too, no artifacts from underlying components are created.
To remove it select:
Offline DB Objects -> <schema> -> <table> and try File.. Erase From Disk.
Thanks

Alter table type from COLUMN to ROW

TABLE type can be changed from ROW to COLUMN (and vice versa) using the ALTER TABLE command .
Lars Breddemann wrote
when considering which data store to choose (which, by the way, can be changed later on as well), you have to take into account:
* will you usually need the complete row (all columns)? If so, row store may be more efficient, as reconstructing the complete row is one of the most expensive column store operations.
* will you need to join the row-store table to a column store table? If so, you should avoid using a different storage type, since using both storage engines in a statement leads to intermediate result set materialization which is another name for bad performance.
* do you want to fill the table with huge amounts of data, that should be aggregated and analysed? If this is the case, the column store is the better option.
As a rule of thumb you may just start with column-store tables and change them to row-store tables when you encounter performance issues.
In general most developers cannot anticipate all important use cases for the tables they design.
This is especially true for living and growing systems.
So, more important than choosing the 'right' storage in the beginning is to monitor the performance and to benchmark the differences when changing the storage engine.
So suppose we have a COLUMN table , but would be requiring to get data from many columns (so would be a very expensive column operation) , would it be advisable to change the table type FROM COLUMN to ROW on the fly . would this be a resource intensive operation if the table has a lot of data ?
Lets suppose , if the above can be done , but there exists a interdependency for the column table (say from another simultaneous operation) , and thus should remain as COLUMN table as such . so what would be the better option in this case .
Creating views is not an option as it seems from the SQL guide , that there was not an option to create a ROW view from a COLUMN table. ?
Edited by: Rajarshi Muhuri on Nov 27, 2011 3:25 AM

Dear Rajashri,
1. you cann't alter table from column to row using alter command.
but you can achieve this through Stored procedure, just Little bit HSQL coding.
I hope upcoming versions SAP Gives like following SQL statements ( following statemnt not works in HANA works in oralce )
   create row table "EFASHION_TUTORIAL"."AAA" as
select
"ARTICLE_COLOR_LOOKUP_ID",
"ARTICLE_ID",
"COLOR_CODE",
"ARTICLE_LABEL",
"COLOR_LABEL",
"CATEGORY",
"SALE_PRICE",
"FAMILY_NAME",
"FAMILY_CODE"
from "EFASHION_TUTORIAL"."ARTICLE_COLOR_LOOKUP";
2. Row & column table two different purpose like OLTP & OLAP.
     when you think about OLAP means modeling use Column.
      when you think about OLTP means real time operations then use Row
Column table is high compress ( 5 - 20X), i don't think you want get any performance issue when read information from column table. that is actual Core engine reading parller process. ( that is Heart of HANA).
Column table purpose quite different like calculations, grouping.. most of DW environment Queires.
Row table is currently system tables in feature row tables as OLTP, it's less compress mode compress to column store.
so finally you write small program convert column to row and row to column

How to select even the column names of a table?

Hello All,
Is there a way to select even the column names of a table in the select statement?
My select from a table (say X) is in a SQL* Plus script that gets invoked by application tier and displays data in the application tier window. User's can then copy the data into a spreadsheet and do their processing. However, I need to give them the column names too along with the data.
Thanks,
Chiru

If there is a middle tier that is selecting and
displaying the data, and that's what the users are
copying from, the middle tier would have to address
its presentation of the data to allow users to
include column names. If this is a common task, the
application should probably be modified to give users
the option of downloading the data in a spreadsheet
directly rather than forcing them to copy and paste
data.Thanks for the reply.
The users don't have to copy paste. The application tier has an options in the "Tools" menu item which allows them to copy the entire output to a file (in my case a txt file which is a pipe delimited). Then they have to do text to columns to get the data into each column of the spreadsheet. I could have directly called the stored procedures from the application tier and created ".csv" files and FTP'd them to the user's folders. However, I am having to go this round about because, I am not getting enough support from the LAN team in FTP'ing etc.
OK I'll think of another workaround.
Thanks,
Chiru

How to find out the selected column in Table Control

Hi all,
      How to find out the selected column in Table Control?
Thanks & Regards,
YJR

Hi,
Let your table control name in Screen painter be TC1.
READ TABLE TC1-COLS INTO WA_COLS (some wok area)
             WITH KEY SELECTED = 'X'.
        IF SY-SUBRC = 0.
          CLEAR: W_DUMMY, W_COL_NAME.
          SPLIT WA_COLS-SCREEN-NAME AT '-' INTO W_DUMMY
                                               W_COL_NAME.
        endif.
W_COL_NAME gives you the column name.
Hope it helps.

Selecting all columns from table in a model query

I have written a model query which joins 4 tables, applies some rules and returns updated rows by selecting 4 columns out of this. Currently it works fine because all 4 columns are from MODEL aliases. Now I need to select 16 more columns in the same query but none of these columns is added in MODEL aliases. When I tried selecting these columns I got oracle error ORA - 32614. Can someone please guide me to include these columns in the same model query?
I tried couple of options but no luck. Here are those options for ready reference:
1. I cannot nest existing model query into another select because there are no columns avaiable to join in output of current query to map with other records.
2. I cannot include all 16 columns in MODEL aliases because some of these columns are actually output of user defined functions.
I am using Oracle database version 11g Release 11.2.0.1.0.

Create a Table Dynamically in WEB Dynpro Java with diferent type of column

Hi everyone, I have a question if is possible to create a table dynamically in Web Dynpro Java?, depending of the RFC consults create the rows dynamically, ,this table must have diferent type of columns, for example link column (when the user click this link execute an action and show a adobe interactive form in another view), image column (show an image depending of the information)
Thank you everyone
Atte Israel

Hello,Israel.
Yes , it is possible through dynamic programming in wdModify of the View.
You can do this ,for example, using cell variants.
IWDTable tab = (IWDTable) view.getElement("TABLE_NAME");
IWDTableStandardCell cellV= (IWDTableStandardCell) view.createElement(IWDTableStandardCell.class,"TableStandardCell"+i);
cellV.setVariantKey("NotEditableVariant");
cellV.setCellDesign((WDTableCellDesign)wdContext.nodeTableDaysTitle().currentTableDaysTitleElement().getAttributeValue("CellDesign"+i));
IWDTextView textViewi= (IWDTextView) view.createElement(IWDTextView.class,"TextView"+i); // -- here you control the type of the object that is displayed in the cell
textViewi.bindText(dayAttrib);
cellV.setEditor(textViewi);
tabColumn.addCellVariant(cellV);
tab.addGroupedColumn(tabColumn,tab.numberOfGroupedColumns());
Using this code you can control even specific cells in the table and not only columns.
Hope this helps you,
Constantine

ADF Table sorting on Select One choice column display value

Hi Team,
We are using an ADF with EJB application.
I have an ADF table, which has a select one choice in it. (The Select one Choice list elements are populated from a java bean).
Presetnly, when we perform the sorting on this SOC column, the table is getting sorted based on SOC value not on the Label.
How to sort this column based on the SOC Lable filed.
Please help us.
Thank you,
Keshav Ch

Hi Frank,
I took a transient column in the Entity and populated this column with the LOV label value.
In the ADF added this coulmn to the table and set it is rendered false.
Set the sortable property of the lov column to the new trasient column.
Now the sort will work with the label filed (Transient Column)
Thank you,

Any help appreciated!

Unfortunately it's a bad idea to store your code samples (or screenshots or whatever) on an external site, because not everybody can get access to such sites, especially if their workplace has limitations on websites that can be visited.
you're pastebin.com is one such site that I cannot access, so I can't see your code.
If you want to paste code and/or data on the forums remember to put the tag: {noformat}{noformat} before _and_ after it, so that the formatting is maintained and it's easier for us to read.

Tabular Form: Conditional column based on another column in table/form?

Hi!
I have 4 columns in table A:
number (the question number)
question (the question to be asked)
type (TEXT, LOV are the 2 valid values)
answer (the answer with text or a selection from the lov table below)
I have 2 columns in table B:
number (the question number)
values (a single value for the lov's)
In table B there can be mutiple rows for each number. Table A and table B
join on the number.
I want to build a tablular form on table A where for each row either a text
box or a select list is displayed depending on the contents of the type column.
So row 1 would display a text box when the type value is text; row 2 would
display a select list when the type value is lov.
Is this even possible? How do I refer to the type column in the conditional for the
answer column? I am guessing that I will need to have 2 answer columns one
that displays when the type column is TEXT and one that displays when the
type column contains LOV. This is OK. Setting up the conditional is display is the issue at this point.
Hopefully I have explained this well enough! :)
Thanks!
Dave Venus

Hi Dave,
Sorry for not responding sooner - I finish work at 3pm GMT.
I'll take your first question first (3:28PM posting according to my display - not sure if you are on GMT time?):
As far as I understand it, using the select_list_from_query() function generates the options that are required in the select list as HTML tags. Each instance of this function should create a SELECT tag and the results of the query should generate one or more OPTION tags within it.
Second question (4:20PM posting):
The HTMLDB_ITEM functions are listed in the documentation - here's a link to the online version:
http://download-east.oracle.com/docs/cd/B19306_01/appdev.102/b14303/api.htm#sthref2524
Most of the examples that I have seen have been on this forum - simply search for HTMLDB_ITEM or one of its functions.
I tend to leave the generation of tabular forms to the wizard as much as possible. The only exceptions are when I need to have access to more than the Primary Key for a row but don't want to show the field on screen. There are examples on the forum about concatenating the HTMLDB_ITEM functions into a single value - this hides ID fields from the user but makes them available to PL/SQL code.
Third question (5:29PM posting)
I did try using DECODE in my questionnaire but not for the feature that you needed. Originally, I wanted to use this to display one of a number of different fields (ie, my date, number or string field as appropriate to the question) but this didn't help as I couldn't get back to the right field during the update. If you have decode working for the select lists, then that's great!
The first column should be hidden or sitting behind a checkbox as this should be the Primary Key for the row and should not be editable by the user nor would it normally be displayed.
As long as your select statement creates the correct output (albeit that you may need to work on the layout!), you should have an updatable form. However, you will need to have the MRU processes in place and the appropriate buttons that trigger these. When I did my questionnaire, I created the form using a wizard to get all of the processes and buttons and then changed the select statement. If you haven't got the processes and/or buttons, we can go through adding these onto your page.
Last question (9:08PM posting)
As explained above, column 1 should normally be hidden. The INPUT tag you detail above is what I would expect to see. The value="6" attribute indicates that 6 is the Primary Key for that row - every row will have the same tag but different values for the "value" attribute. So, if it is hidden and these are the tags you see doing a View Source on the page, then everything is correct.
OK. So now we have the data on screen and (hopefully?) we have the correct processes and buttons on the page.
The next step would be validation and update of the data.
Validation of the data can be handled by a normal page process - I can let you have example code if you want to validate the data (this will also explain how to loop through the rows - there are also methods that you can use to do this in javascript if you want). Updates should be handled by the processes and buttons on the page - again, if you haven't got these we can go through adding them in (although, if you haven't yet formatted your page, you may find it quicker to copy your select statement and create the page again using the same select statement).
ORA-20001 errors are user defined errors. Do you mean the "data has changed" errors? If so, you will probably need to include the MD5 checksum functionality (it's shown in the document linked above).
Finally, we'll keep this thread going so that you have all of your workings and my responses in one place, if that's ok with you?
Regards
Andy
