How can I list all the column names of a table by programming?

Hi,
Now I want to write an function which has the following features:
Firstly, The function was given a parameter as table name.
Then, it will lists all the columns names of the table.
e.g
table: person
---firstName------lastName----+
       Michale               Jackson
We can get the columns 'firstname' and 'lastName' by calling the function with table name 'person'.
And I also wonder that where I can get reference book or any other materials?
Thanks.

hi,
hope the below code helps u. Just take the headee which contains the field name and split it like below and compare it with the field name u want here 'last name'.
here,
'First name' will be in wt_filedata1 and remaining field names in wt_filedata2, so 'do' continues.
c_tab must be the separator, either , or + or tab etc..
CODE:
read table person into wl_header index 1.
do.
    split wl_header at c_tab into: wt_filedata1 wt_filedata2.
    if wt_filedata1 <> 'lastname'.
      cnt1 = cnt1 + 1.
      wl_header = wt_filedata2.
    else.
      exit.
    endif.
enddo.
Please reward if it is useful.

Set the column name of a table in a list box

is there any code to set the column name of a table in a list box at oracle devloper 6i?
pls help.

I dont want to go for pl/sql . It should work any table.You want Dynamic SQL without using PL/SQL? Tricky. I'm sure there's a possible way using some very complex and convoluted XML functionality of SQL but in reality you are asking for something that isn't natural to SQL queries, especially if you are expecting a dynamic number of columns to be produced for each row of data. SQL expects a table structure, including output formats, to be a defined number of columns with any number of rows, not a defined number of rows with any number of columns.
Perhaps if you explain why you need this sort of functionality then we may be able to offer a better solution.

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 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

Search for column name in DB tables

Hi Guys
Is it possible to search column name when we do not know the corresponding table in the databse
Cheers
shabar

You can use the data dictionary to search though a list of all column names. The <strike>table</strike> data dictionary view is ALL_TAB_COLUMNS.
Lets assume you want to search for ID columns:
example
select owner, table_name, column_name
from all_tab_columns
where column_name = 'ID';Edited by: Sven W. on Jun 21, 2011 1:47 PM

How to get only column names from different tables as single table columns

Hi All,
I have one requirement in which we want only column names from different tables.
for example :
I have three tables T1 ,T2, T3 having
col1 clo2 clo3 --> T1 ,
col3 col5 ,clo6 --> T2 ,
Clo6 col8 col9 --> T3
columns i want to get only all Column names from all table as single Resultset not any data from that how can i get that empty resultset
because this empty result i want to bind in datagridview(front end) as Empty resultset
Please tell me anyways to do this
Niraj Sevalkar

If I understand you want an empty result set, just with metadata. SET FMTONLY do the trick:
SET FMTONLY ON
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
SET FMTONLY OFF
Another alternative is to include an imposible contition
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
WHERE 1 = 0
If you are using a SqlDataAdapter in your client application. You can use the FillSchema method. the select command may be any select statement that returns the columns you want. Under the covers FillSchema will call SET FMTONLY ON.
If you are using SqlCommand.ExecuteReader you can pass SchemaOnly to CommandBehavior argument. SET FMTONLY ON is called under the covers. Again the select command may be any select statement that returns the columns you want.

What is the use of Position Column Name in USER_CONS_COLUMNS Table

Please let me know the purpose of POSITION Column Name in USER_CONS_COLUMNS Table.
Example :
Created this below Table having two constraints 1.Primary Key 2.Check Constraint
CREATE TABLE A(ID NUMBER PRIMARY KEY,NAME VARCHAR2(30),SAL NUMBER CHECK (SAL > 0))
When i execute the below query
SELECT POSITION,CONSTRAINT_NAME FROM USER_CONS_COLUMNS WHERE TABLE_NAME = 'A'
it displays the data :
POSITION CONSTRAINT_NAME
1 SYS_C005488
SYS_C005487
Only for the first record it displays the POSITION but not for the second row.
Kindly help me on this.

SQL> CREATE TABLE A(
2     ID1 NUMBER
3   , ID2 NUMBER
4   , NAME VARCHAR2(30)
5   , SAL NUMBER CONSTRAINT A_SAL_POSITIVE CHECK (SAL > 0)
6   , CONSTRAINT A_PRIMARY_KEY PRIMARY KEY (ID1, ID2)
7 )
8 /
Table created.
SQL> SELECT CONSTRAINT_NAME, POSITION, COLUMN_NAME
2    FROM USER_CONS_COLUMNS
3   WHERE TABLE_NAME = 'A'
4   ORDER BY CONSTRAINT_NAME, POSITION
5 /
CONSTRAINT_NAME                  POSITION COLUMN_NAME
A_PRIMARY_KEY                           1 ID1
A_PRIMARY_KEY                           2 ID2
A_SAL_POSITIVE                            SALA primary key constraint can have multiple columns - the position shows the order the columns are in the primary key definition (and thus also in the pk supporting index.)
A check constraint does not have any such ordering of the columns involved, so therefore position is null.

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.

How to know primary key column name form a table name in sql query

Suppose I only know the table name. How to get its primary key column name from the table name?
Thanks

Views don't have primary keys though their underlying tables might. You'd need to pick apart the view to determine where it's columns are coming from.
You can select the text of the view in question from user_views.
