May be a rude way .. but it works.
Add narrative view and use Java script to change the column headings based on the variables.
<script language="javascript" type="text/javascript">
var a = document.getElementById('idResultsTableParent');
var rows= a.getElementsByTagName('tr');
rows[1].cells[1].innerText ="@{Presentation Variable}";
</script>

How to dynamically set the name of the generated PDF file sent by email

Hello,
I am using Reports 10g and I managed to send PDF reports by email, specifying the recipient, subject, format etc, using the reports servlet URL.
But there is one thing that I cannot find a way to do: I want to dynamically set the name of the attached file. It defaults to the name of the RDF file (eg monthly_sales.pdf). I would like it to be something more meaningful (eg monthly_sales_072010.pdf, where 072010 is the month and year passed by parameters).
Is it possible to do it?
Thanks

How to dynamic set table names

In our application, the table name can be set at runtime by the customer. So is there a way in Toplink JPA to set table name at runtime (thru annotation or orm.xml) or programatically? Thanks.

Our application will host several domains at once. Each domain will get its own set of database tables for each module it uses. We keep them seperate by using a unique prefix. An example would be domainA.com's blog post table would be called domainA_blogPost, while domainB.com's will be domainB_blogPost. Both tables are the same, except for the name. The name needs to be specified at runtime since the central service controller tells the rest of the application which domain it is servicing and thus which set of tables to use. We will be adding domains dynamically all the time and we can't afford to create new entity sets and recompile the back end for every domain we add. I have been looking at the API and wonder if this is as simple as implementing a solution in our application, or am I going to have to tweek the implementation of toplink?

Setting Column Names in Dynamic Pivot Query

Hi all,
I'm having trouble setting column names in a dynamic pivot query and was wondering if someone could please help me figure out what I need to do.
To help you help me, I've setup an example scenario in my hosted account. Here's the login info for my hosted site at [http://apex.oracle.com]
Workspace: MYHOSTACCT
Username : DEVUSER1
Password : MYDEVACCTAnd, here is my test application info:
ID     : 42804
Name   : dynamic query test
Page   : 1
Table 1: PROJECT_LIST         (Alias = PL... Listing of Projects)
Table 2: FISCAL_YEAR          (Alias = FY... Lookup table for Fiscal Years)
Table 3: PROJECT_FY           (Alias = PF... Intersection table containing project fiscal years)
Table 4: PROJECT_FY_HEADCOUNT (Alias = PFH... Intersection table containing headcount per project and fiscal year)Please forgive the excessive normalization for this example, as I wanted to keep the table structure similar to my real application, which has much more going on.
In my sample, I have the "Select Criteria" region, where the user specifies the project and fiscal year range that he or she would like to report. Click the Search button, and the report returns the project headcount in a pivoted fashion for the fiscal year range specified.
I've got it working using a hard-coded query, which is displayed in the "Hardcoded Query" region. In this query, I basically return all years, and set conditions on each column which determines whether that column should be displayed or not based on the range selected by the user. While this works, it is not ideal, as there could be many more fiscal years to account for, and this is not very dynamic at all. Anytime a fiscal year is added to the FISCAL_YEAR table, I'd have to update this page.
So, after reading all of the OTN SQL pivot forums and "Ask Tom" pivot thread, I've been able to create a second region labeled "Dynamic Query" in which I've created a dynamic query to return the same results. This is a much more savvy solution and works great; however, the column names are generic in the report.
I had to set the query to parse at runtime since the column selection list is dynamic, which violates SQL rules. Can anyone please help me figure out how I can specify my column names in the dynamic query region to get the same column values I'm getting in the hardcoded region?
Please let me know if you need anymore information, and many thanks in advance!

Hi Tony,
Thanks so much for your response. I've had to study up on the dbms_sql package to understand your function... first time I've used it. I've fed my dynamic query to your function and see that it returns a colon delimited list of the column names; however, I think I need a little more schooling on how and where exactly to apply the function to actually set the column names in APEX.
From my test app, here is the code for my dynamic query. I've got it in a "PL/SQL function body returning sql query" region:
DECLARE
v_query      VARCHAR2(4000);
v_as         VARCHAR2(4);
v_range_from NUMBER;
v_range_to   NUMBER;
BEGIN
v_range_from := :P1_FY_FROM;
v_range_to   := :P1_FY_TO;
v_query      := 'SELECT ';
-- build the dynamic column selections by looping through the fiscal year range.
-- v_as is meant to specify the column name as (FY10, FY11, etc.), but it's not working.
FOR i IN v_range_from.. v_range_to LOOP
    v_as    := 'FY' || SUBSTR(i, 3, 4);
    v_query := v_query || 'MAX(DECODE(FY_NB,' || i || ',PFH_HEADCOUNT,0)) '
      || v_as || ',';
END LOOP;
-- add the rest of the query to the dynamic column selection
v_query := rtrim(v_query,',') || ' FROM ('
    || 'SELECT FY_NB, PFH_HEADCOUNT FROM ('
    || 'SELECT FY_ID, FY_NB FROM FISCAL_YEAR) A '
    || 'LEFT OUTER JOIN ('
    || 'SELECT FY_ID, PFH_HEADCOUNT '
    || 'FROM PROJECT_FY_HEADCOUNT '
    || 'JOIN PROJECT_FY USING (PF_ID) '
    || 'WHERE PL_ID = ' || :P1_PROJECT || ') B '
    || 'ON A.FY_ID = B.FY_ID)';
RETURN v_query;
END;I need to invoke GET_QUERY_COLS(v_query) somewhere to get the column names, but I'm not sure where I need to call it and how to actually set the column names after getting the returned colon-delimited list.
Can you (or anyone else) please help me get a little further? Once again, feel free to login to my host account to see it first hand.
Thanks again!

How to use the column names generated from Dynamic SQL

Hi,
I have a problem with Dynamic SQL.
I have written an SQL which will dynamically generate the Select statement with from and where clause in it.
But that select statement when executed will get me hundreds of rows and i want to insert each row separately into one more table.
For that i have used a ref cursor to open and insert the table.
In the select list the column names will also be as follows: COLUMN1, COLUMN2, COLUMN3,....COLUMNn
Please find below the sample code:
TYPE ref_csr IS REF CURSOR;
insert_csr ref_csr;
v_select VARCHAR2 (4000) := NULL;
v_table VARCHAR2 (4000) := NULL;
v_where VARCHAR2 (4000) := NULL;
v_ins_tab VARCHAR2 (4000) := NULL;
v_insert VARCHAR2 (4000) := NULL;
v_ins_query VARCHAR2 (4000) := NULL;
OPEN insert_csr FOR CASE
WHEN v_where IS NOT NULL
THEN 'SELECT '
|| v_select
|| ' FROM '
|| v_table
|| v_where
|| ';'
ELSE 'SELECT ' || v_select || ' FROM ' || v_table || ';'
END;
LOOP
v_ins_query :=
'INSERT INTO '
|| v_ins_tab
|| '('
|| v_insert
|| ') VALUES ('
|| How to fetch the column names here
|| ');';
EXECUTE IMMEDIATE v_ins_query;
END LOOP;
Please help me out with the above problem.

I Built the statement as required but i need the column list because the first column value of each row should be inserted into one more table.
So i was asking how to fetch the column list in a ref cursor so that value can be inserted in one more table.

Then add a RETURNING INTO clause to the query to have Oracle return the first column values into a collection.

How to set column names when not using object of row data in constructer

hello i am using JTable constructer as
public JTable(int numRows,
int numColumns)
can i set column names for the columns .How?

hi,
sure you can: Create a subclass of DefaultTableModel and overwrite the method public String getColumnName(int) which returns the column name of a specific column. Then use this subclass as the data model for the table.

Hey john,
My requirement is as follows
I have created a Rank for Total sales by Region wise i.e RANK(SUM(Dollars By Region)) in a pivot table.
My pivot table looks like this
COLUMN SELECTOR: TOTAL US , REGION , DISTRICT , MARKET
---------------------------------------------------- JAN 2009          FEB 2009        MAR 2009
RANK              REGION                  DOLLARS           DOLLARS        DOLLARS DOLLARS
1 CENTRAL 10 20 30 40
2 SOUTHERN 10 30 30 70
3 EASTERN 20 20 20 60
4 WESTERN 10 20 30 40
When i select the District in column selector
Report has to display rank based on Total Sales by District. i.e
------------------------------------------------- JAN 2009         FEB 2009       MAR 2009
RANK             DISTRICT              DOLLARS           DOLLARS        DOLLARS DOLLARS
for this i need to change the fx of rank i.e RANK(SUM(Dollars By Region)) to RANK(SUM(Dollars By District)) and fx of Region i.e Markets.Region to Markets.District dynamically.
so , i need to capture column name of the value selected from the column selector and dynamically i need to update the fx 0f RANK & fx of region.
do you have any solution for this?

Hi,
What version of oracle are you using? If it is 9i,
then you can the command
alter table <table_name> rename column <column_name> to <new_column>;
if it is 8i or earlier, you can create a view with the required names.

Always post the oracle version and the platform you are using to get better response.

How to pull only column names from a SELECT query without running it

How to pull only column names from a SELECT statement without executing it? It seems there is getMetaData() in Java to pull the column names while sql is being prepared and before it gets executed. I need to get the columns whether we run the sql or not.

Maybe something like this is what you are looking for or at least will give you some ideas.

How to rename a column name in a table? Thanks first!

I tried to drop a column age from table student by writing the
following in the sql plus environment as :
SQL> alter table student drop column age ;
but I found the following error
ORA-00905: 缺少关键字 (Lack of Key word)
I have oracle enterprise edition 8.0.5 installed at windows 2000
thank you
And I want to know how to rename a column name in a table?
thanks

In Oracle 8i, your syntax would have worked. However, if I
recall correctly, in Oracle 8.0, you can't rename or drop a
column directly. One way to get around that problem is to
create another table based on a select statement from your
original table, providing the new column name as an alias if you
want to change the column name, or omitting that column from the
select statement if you just want to drop it. Then drop the
original table. Then re-create the original table based on a
select statement from the other table. Then you can drop the
other table. Here is an example:
CREATE TABLE temporary_table_name
AS
SELECT age AS new_column_name,
       other_columns
FROM   student
DROP TABLE student
CREATE TABLE student
AS
SELECT *
FROM   temporary_table_name
DROP TABLE temporary_table_name
Something that you need to consider before doing this is
dependencies. You need to make a list of all your dependecies
before you do this, so that you can re-create them afterwards.
If there are a lot of them, it might be worthwhile to do
something else, like creating a view with an alias for the
column or just providing an alias in a select. It depends on
what you need the different column name for.

How to get the Column names of output that is displaying in Sql Developer(Oracle 11g).

Hi,
    I am using OCCI to interact with DB through code, which means I am writing a vc++ file to interact with Data Base and execute the Stored Procedure which I am calling from the C++ Code. And also displaying the output of the Stored Procedures to the Front End. I am succeeded in this, but now I should be able to display the Column names of the output to Front End. Can any one help me on this.
Example:
Sno |   Sname
------- |-------------
1          ABC
2          DEF
I am getting (1,ABC) and (2,DEF) as the output of the Stored Procedure but I need the Column names also to display. How to get them.
Thanks in Advance..:)

Look at Re: exporting csv via pl/sql - select statement?
It has an example how to extract the column name from a cursor. You have to check, whether you can use DBMS_SQL.DESCRIBE_COLUMNS
Your procedure might need another out parameter, that returns the column names , e.g. as comma separated list or as varray.

How to rename the column name in oracle 8i?

hi,
Does anyone know how to rename the column name in oracle 8i?My method was drop the relationship key first then delete the old column,finally add the new column.
Thanks for your replay.
jing

There is no facilty to rename a column name in Oracle 8i. This is possible from Oracle 9.2 version onwards.
For you task one example given below.
Example:-
Already existed table is ITEMS
columns in ITEMS are ITID, ITEMNAME.
But instead of ITID I want ITEMID.
Solution:-
step 1 :- create table items_dup
as select itid itemid, itemname from items;
step 2 :- drop table items;
step 3 :- rename items_dup to items;
Result:-
ITEMS table contains columns ITEMID, ITEMNAME
