How to modify a column name & How to modify a constraint name

How to modify a column name?
How to modify a primary key constraint name if the pk has been referenced by another foreign key?
Thanks.

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

I would like to know how can I modify one column of current and next record depending of some criteria using SQL2012?
The criteria is:
Type should always flow F->T
if current abs(amount)> next abs(amount) then groupid = 'PD'
if current abs(amount)< next abs(amount) then groupid = 'PI'
there is no case when those amounts will be equals
where current(custid) = next(custid) and current(service) = next(service) and groupid is null
Any help will be really apreciated.
Thank you

I tried that and got this error
'LAG' is not a recognized built-in function name.
You said you were using SQL 2012, but apparently you are not. The LAG function was added in SQL 2012. This solution works on SQL 2005 and SQL 2008:
; WITH numbering AS (
   SELECT groupid,
rowno = row_number() OVER (PARTITION BY custid, service ORDER BY date, id)
   FROM   #ServiceChange
), CTE AS (
   SELECT a.groupid,
CASE WHEN abs(a.amount) < abs(b.amount) THEN 'PD'
   WHEN abs(a.amount) > abs(b.amount) THEN 'PI'
END AS newgroupid
   FROM numbering a
   JOIN numbering b ON b.custid = a.custid
AND b.service = a.service
AND b.rowno   = a.rowno - 1
UPDATE CTE
SET   groupid = newgroupid

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 pull only column names from a SELECT query without running it

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 can I include value of Sharepoint's Modified or Modified By column in a Word document?

I know how to do this with SP's Version field (by enabling labels in the Information management policy settings for documents in my SP library), but I don't know if any other out-of-the-box SP fields can also be used as a label.
I specifically want to use the SP Modfied and Modified By columns, but when I try to input {Modified} or {Editor} or {Last_x0020_Modified} or {MyEditor} or {ModifedBy} into the label format field in the Information management policy settings, I get the error
(this error is what is shown when I tried {Modified}):
There were errors on the page: The label reference, Modified, can not be used in a label.
The only field that seems to work as a label is {Version}.

Whoops! This is partially my answer, at least for the SaveDate. But I'm having a problem with the
LastSavedBy field.
What I'm trying to do is have both of these in the header of my documents in my SharePoint library. So I've made a Word template for the library that uses your solution in the header. When I first open a new document, the
SaveDate looks like 0/0/0000, which is right because that's the format I chose and I haven't actually saved the document yet.
The LastSavedBy is blank, so I figured that was correct, again because I haven't saved the document yet.
After I save the document, check it in and then open it again, the correct
SaveDate appears.
I figured the same thing would work with the LastSavedBy field. But it doesn't. When I reveal the field codes, it is correct: { LASTSAVEDBY \* MERGEFORMAT }. I know that's correct, because if I manually delete that field but then add
it in again, it THEN appears to work consistently.
If I use the Author field in Word instead of the LastSavedBy
field, it works perfectly. But I assume the Author field is SharePoint's
Created By column, and I don't want that. I want the Modified By column. But I can't get that to work in the template the library uses. So It's useless to me, unless I train all my users to manually insert that Quick Part for
every new document they create in the library.
I'm figuring the problem above has something to do with a new document initially not being saved or checked in, but I don't know if anything can be done to correct this.

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.

Badunit, thanks for your reply. I just went into Mail/Preferences/Accounts, "full name" field is filled correctly with my name. This happens to only certain recipients, and not every emails. Sometimes my name shows and sometime it doesn't show. And this only started to occur recently.

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

Looks like the presentation column got Alias before your BMM changes, so in your case renaming logical column and deleting alias is not good to go.

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?
