Dynamic creation of table with variable field-names

HI
I am looking for a way in order to create a table during runtime. The problem is that the field names of the table are provided in another table.
TO illustrate the case at hand, an example:
The initial table contains the fields
UserID - attribut_name - attribute_value
Example Data
d00587 - first_name    - Jon
d00587 - last_name     - Smith
d00587 - age           - 48
d00127 - first_name    - Jack
d00127 - last_name     - Daniels
d00127 - position      - Manager
Now I need to create a table per User that looks as follows:
for user d00587
first_name - last_name - age
**Values
Jon         - Smith      - 48
for user d00127
first_name - last_name - positioin
Jack        - Daniels    - Manager
I split the initial table by sorting it according to userID and then looping into an itab with an AT END OF userid, thus I receive the table per user:
Example iTab
UserID - attribut_name - attribute_value
Example Data
d00587 - first_name    - Jon
d00587 - last_name     - Smith
d00587 - age           - 48
However I have no clue on how to create a new internal table with field-names = attribute_name.
Does anybody have an idea or example code for this?
Thanks a lot for your help,
Kind regards,
Mingolo

Hello Minima
Here is some sample coding:
DATA:
gt_fcat type lvc_t_fcat,
gdo_data TYPE REF TO data.
FIELD-SYMBOLS:
<gt_itab> TYPE table.
CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
EXPORTING
*     I_BUFFER_ACTIVE              =
    i_structure_name             = 'MARA'
*     I_CLIENT_NEVER_DISPLAY       = 'X'
*     I_BYPASSING_BUFFER           =
CHANGING
    ct_fieldcat                  = gt_fcat
EXCEPTIONS
    inconsistent_interface       = 1
    program_error                = 2
    OTHERS                       = 3
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
CALL METHOD cl_alv_table_create=>create_dynamic_table
EXPORTING
*      I_STYLE_TABLE             =
    it_fieldcatalog           = gt_fcat
IMPORTING
    ep_table                  = gdo_data
*      E_STYLE_FNAME             =
EXCEPTIONS
    generate_subpool_dir_full = 1
    OTHERS                    = 2.
IF sy-subrc <> 0.
*   MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*              WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
ASSIGN gdo_data->* TO <gt_itab>.
In your case, you would call the function module with your tables (D00587, D00127). Remove all fields from the fieldcatalog that you do not need before calling the static method.

Hi,
Wher do you have the data?
You can define a work area and internal table of two rows..
wa-row1 = 'yourdata'
wa-row2 = 'your data'
append wa to itab.
wa-row1 = 'yourdata'
wa-row2 = 'your data'
append wa to itab.
wa-row1 = 'yourdata'
wa-row2 = 'your data'
append wa to itab.
wa-row1 = 'yourdata'
wa-row2 = 'your data'
append wa to itab.
wa-row1 = 'yourdata'
wa-row2 = 'your data'
append wa to itab.
If you have your data in Db table then you need to write a select query..
select <fields,,,> from DBtable into tableITAb.
Be clear with your question we can help you...

How can I check if there is a table with the given name ?

I'm using 8i and 9i.
Could anybody teach me how to check if there is a table with a certain name in SQLPLUS without using SELECT
statement ?
I want to use the following logical procedure.
if exists "table_to_be_deleted" then drop table "table_to_be_deleted"
Or, is there any system table that I can check the names of tables like
count = select "table_to_be_deleted" from "an_oracle_system_table"
if ( count != 0 ) then drop table "table_to_be_deleted"
Thanks,
John

Just create it, but be aware that DDLs can't be executed directly from Pl/Sql, so you'll have to use dynamic Sql, e.g. :

Table created.

3 exception
4 when others then
5 null;
6 end;
SQL> /
drop table test;

Pivot table with variables columns

I need a helo to pivot table with variable columns,
I have a pivot table :
SELECT a.*
FROM (SELECT codigo_aluno,nome_aluno , id_curso,dia FROM c_frequencia where dia like '201308%') PIVOT (sum(null) FOR dia IN ('20130805' ,'20130812','20130819','20130826')) a
but I need to run the select with values for dia , getting from a other table :
SELECT a.*
FROM (SELECT codigo_aluno,nome_aluno , id_curso,dia FROM c_frequencia where dia like '201308%') PIVOT (sum(null) FOR dia IN (
select dia from v_dia_mes )) a
thank you

The correct answer should be "Use the Pivoted Report Region Plugin".
But, as far as I know, nobody has created/posted that type of APEX plugin.
You may have to use a Basic Report (not an IR) so that you can use "Function returning SELECT" for your Source.
You would need two functions:
One that dynamically generates the Column Names
One that dynamically generates the SELECT statement
These should be in a PL/SQL Package so that the later can call the former to ensure that the column data matches the column names.
i.e. -- no 'SELECT *'

How to create table with variable

i want to set name test then any given number by variable so i can create many table.
so how to add it in create table command.
i tried create table test||:var (column names) but it didnt work.
so plz suggest me how to do it ?
thxs

Actually this is good.
It has nothing to do with database design. A database is not a garbage bin.
You need to do several things
a) make sure your design is normalized so you don't have identical tables.
b) In future posts specify a platform and a version and the tool you are using to create the table
c) if the tool is sql*plus learn about substitution variables aka DEFINEs.

Hi,
Right click the mouse->create->table
If you want 5 columns, you need to declare 5 cells in one line type of the table
Click on Table -> Details, then do the following
Line Type 1 2 3 4 5
L1 2mm 3mm etc
Here specify the width of the columns as many as you want..
then in the header/main area of the table, click create Table Line, Rowtype is L1, automatically 5 cells will come,In each cell create a text element, display the variable to be printed there.

Is it possible to have 2 tables with the same name in an Orable database?

Hello,
I'm a complete Oracle newbie so please excuse my question if it's stupid.
I was trying to create 2 tables with the same name using different tablespaces but it does not seem to work. Like this (second time just change the name of the tablespace):
CREATE TABLE test_tbl (
id INTEGER,
status VARCHAR2(10),
last_modified DATE DEFAULT SYSDATE
TABLESPACE tblspc1Is it in general in Oracle possible to acquire this goal?
Thanks a lot!
P.S. I have already created the needed tablespaces
CREATE TABLESPACE tblspc1 DATAFILE 'tblspc1.dbf' SIZE 10MEdited by: 808239 on 02-Mar-2011 02:18

It is not possible to create two tables with same name in same schema.
A user can own one schema with his own name and another with the schema name SYS.
For this you have to grant sysdba privilage to the user and then have to connect using sys password or with the password specified in password file.
But this still you have to access to the table in sys schema using sys.table_name.
Hope Answered tthe Question.

Reference all tables with the same name

If I have multiple worksheets that each have an identically structured table "Test", is it possible to create a formula in a cell of another worksheet that references the same range of cells in every table "Test"? So far I haven't found a way to reference cells in a table with an ambiguous name without having to prepend the worksheet name to the reference like so: 'Worksheet 1' :: Test :: B3:C4. What I want to be able to do is say Test :: B3:C4 and have the formula reference B3:C4 in all "Test" tables.
Thanks!

You've picked the correct descriptive term. Such a reference would indeed be "ambiguous".
You might be able to reference a set of disconnected ranges of cells, but each range would have to be explicitly described.
You might be able to collect the values in the cells into a single array in a single table, then reference that array in your formula.

Barry
PS: "Sheets" in Numbers have little in common with "Worksheets" in MS Excel. Using the Numbers vocabulary can help keep the distinction more clear, and avoid unwarranted expectations.

Understanding logminer results -- inserting row into table with CLOB field

In using log miner I have noticed that inserts into rows that contain a CLOB (I assume this applies to other LOB type fields as well, have only tested with CLOB so far) field are actually recorded as two DML entries.
--the first entry is the insert operation that inserts all values with an EMPTY_CLOB() for the CLOB field
--the second entry is the update that sets the actual CLOB value (+this is true even if the value of the CLOB field is not being set explicitly+)
This separation makes sense as there may be separate locations that the values are being stored etc.
However, what I am tripping over is the fact the first entry, the Insert, has a RowId value of 'AAAAAAAAAAAAAAAAAA' which is invalid if I attempt to use it in a flashback query such as:
SELECT * FROM PERSON AS OF SCN #####' where RowId = 'AAAAAAAAAAAAAAAAAA'The second operation, the Update of the CLOB field, has the valid RowId.
Now, again, this makes sense if the insert of the new row is not really considered "+done+" until the two steps are done. However, is there some way to group these operations together when analyzing the log contents to know that these two operations are a "+matched set+"?
Not a total deal breaker, but would be nice to know what is happening under the hood here so I don't act on any false assumptions.
Thanks for any input.
To replicate:
Create a table with CLOB field:
CREATE TABLE DEVUSER.TESTTABLE
        ID NUMBER
       , FULLNAME VARCHAR2(50)
      , AGE NUMBER
      , DESCRIPTION CLOB
       );Capture the before SCN:
SELECT DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER FROM DUAL;Insert a new row in the test table:
INSERT INTO TESTTABLE(ID,FULLNAME,AGE) VALUES(1,'Robert BUILDER',35);
     COMMIT;Capture the after SCN:
SELECT DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER FROM DUAL;Start logminer session with the bracketing scn values and options etc:
EXECUTE DBMS_LOGMNR.START_LOGMNR(STARTSCN=>2619174, ENDSCN=>2619191, -
           OPTIONS => DBMS_LOGMNR.DICT_FROM_ONLINE_CATALOG + DBMS_LOGMNR.CONTINUOUS_MINE + -
           DBMS_LOGMNR.COMMITTED_DATA_ONLY + DBMS_LOGMNR.NO_ROWID_IN_STMT + DBMS_LOGMNR.NO_SQL_DELIMITER)Query the logs for the changes in that range:
SELECT

Scott,
Thanks for the reply.
I am inserting into the table over a database link.
I am using the new version of HTML Db (2.0)
HTML Db is connected to an Oracle 10 database I think, however the table I am trying to insert data into (via the database link) is in an Oracle 8 database - this is why we created a link to it as we couldn't have the HTML Db interacting with the Oracle 8 database directly due to compatibility problems (or so I've been told)

That is a quirk of Pagesthat it applies only one record per page.

Subform with table with expanding fields - please help!

I am a new user of LiveCycle Designer ES and need help with a form. I've made so many changes within the form that I have now lost track and don't know where to start to fix the following two issues:
The form itself is one Master Page that needs to repeat, based on the amount of data entered. This is not happening.
Within the form is a Table with expanding fields. It is when the last field is full that I need a new page created.Also, as the table expands, it overwrites the Footer, which is a subform. The footer is set to have a top margin (.25).
Any assistance would be much appreciated. Thank you!

I want to update the DB table with following internal table records.
If internal table records = db table records are same then Update....else insert from internal table to db table.
But here, SSOUR is key field so i am not able to use
MODIFY dbtab from itab.
It results me , entries in internal table are inserted into db table.
So i have double records.
Is there any statement which updates the key field? and if no fields in db table then insert it?
Regards

hi,
u cannot update akey field.u can update only non key fields by using key field as a selection criteria.For example if u go to sm30 if u enter any table for inserting values, the key field will always be greyed out it is not succumbed to chnges.but u can insert value into ,if ur inserting and in the insert staemnet if u have key field which is already present in the table it will return sy-subrc = 4 otherwise it will insert the record and return 0.
eg for update :
UPDATE zdm_wtyprof SET upload_status = 'S'
                         WHERE spart = wa_upd-spart.
here spart is the key field and it will update the status field in the table as S.
if updated succesfully it will return 0.
SIMILARLY U CAN USE select.

Many to many join table with different column names

Hi have a joint table with different column names as foreign keys in the joining
tables...
e.g. i have a many to many reltnshp btwn Table A and Table B ..and join table
C
both have a column called pk.
and the join table C has columns call fk1 and fk2
does cmd require the same column name in the join table as in the joining table?
are there any workarounds?
thanks

HI,
No, the foreign key column names in the join table do not have to match the primary
key names in the joined tables.
