Rename columns in Presentaion Layer

Hi,
I need to change the column names in the Presentaion Layer. I need only the beginning of the word to be uppercase. Do I have to go to BMM layer and use the rename wizard and get all the columns again to presentation layer. We have a lot of columns so manually doing it would be very time consuming. I am trying to do in Presenation Layer itself using Rename wizard but somehow the 'next' field is not highlighted to go to the next step. Any suggestions? Also if I change any column name in presentation layer manually do I also have to chnage the name in BMM layer as well.

Hi,
Keeping the column names consistent in BMM and presntation layer is best suggested as diffrent names in both the layers can lead to confusion .As Aliastair suggested if you rename in presentation layer then it will create aliases to Old names,If someone delete that alias then you will get view display error in report.So follow a simple approach and keep names consistent in both the layesr unless and until its very urgent to rename columns in presentation layer.
Thanks
Sandeep

Rename columns in Presentation layer

Hi Experts,
I Have one BMM layer table with 2 groups columns like
BMM Table
Sales
Revenue
Sum
Sales_ B Group
Revenue_ B Group
Sum_ B Group
Now I want to show these columns in two tables i.e. A table and B table with same column names in presentation layer as below:
Presentation A table Presentation B table
Sales Sales
Revenue Revenue
Sum Sum
In BMM layer it should be Sales_ B Group but in presentation table it should show as Sales as vice verse for other 2 columns for B group columns
If I rename Sales_ B Group as Sales in BMM layer it won’t accept because already sales column is there my requirement is in BMM layer in should as Sales_ B Group but in presentation layer the same column it should show as Sales .

Hi Rafi,
Can you right click on your presenatation layer and create a new presentation table (EG: Table A) -- and then move the columns from bmm layer and rename them as per your req.
Now right click again.. create one more Pres. table (EG: Table B) -- and then move the columns from bmm simply drag and drop and rename as per your req.
Thank you.

Error while renaming column in Apex 3.2.1

Hi,
I am getting the following error while renaming column in Oracle Apex 3.2.1 through SQL workshop:
"ORA-24344: success with compilation error"
Interestingly, it only gives an error when I rename the column again to its original name. For example, if I renaming the column X to X1 (no problem) but renaming back to X, I get this error. Same is true for X to X1 to X2 without any issues but renaming back from X2 to either X1 or X, I get the same error.
Any insight into this issue would be very helpful and greatly appreciated.
Thanks,

I've moved a step ahead, getting the new apex screen at http://127.0.0.1:8080/apex/ and can also login to my application. However there is no image for Application Express on http://127.0.0.1:8080/apex/ and I cannot click on the Login button. Hitting http://127.0.0.1:8080/i/ does list down the images. Any clue on what could be the problem?
For others reference: I'm not sure what was wrong, but I tried the entire steps again, with the 2 changes: shutdown the listener and job process ( in step 3.1) before running 'apexins' and second that I installed on SYSAUX and not USERS (in step 4)
1. Downloaded apex_3.2.1.zip to C:\Software
2. unzip apex_3.2.1.zip to C:\Software\apex
3. started command prompt and set these variables
set ORACLE_HOME=C:\oraclexe\app\oracle\product\10.2.0\server
set ORACLE_SID=xe
set ORACLE_PATH=C:\oraclexe\app\oracle\product\10.2.0\server\bin
set LD_LIBRARY_PATH=C:\oraclexe\app\oracle\product\10.2.0\server\lib
3.1 Shutdown the listener and job services
4.

Rename column in Oracle 9i

Can we rename column in Oracle 9i?
Thanks,
Alex

I don't think it should be that complicated unless you have any contraints to it. Do you have any foreign keys that are referencing to this particular table ? Also let me know what syntax are you using for dropping the column ?
Also look at the following example, try these things on some test/dummt table first.
Dropping a Column: Example
===========================
This statement illustrates the drop_column_clause with CASCADE CONSTRAINTS. Assume table t1 is created as follows:
CREATE TABLE t1 (
pk NUMBER PRIMARY KEY,
fk NUMBER,
c1 NUMBER,
c2 NUMBER,
CONSTRAINT ri FOREIGN KEY (fk) REFERENCES t1,
CONSTRAINT ck1 CHECK (pk > 0 and c1 > 0),
CONSTRAINT ck2 CHECK (c2 > 0)
An error will be returned for the following statements:
/* The next two statements return errors:
ALTER TABLE t1 DROP (pk); -- pk is a parent key
ALTER TABLE t1 DROP (c1); -- c1 is referenced by multicolumn
-- constraint ck1
Submitting the following statement drops column pk, the primary key constraint, the foreign key constraint, ri, and the check constraint, ck1:
ALTER TABLE t1 DROP (pk) CASCADE CONSTRAINTS;
If all columns referenced by the constraints defined on the dropped columns are also dropped, then CASCADE CONSTRAINTS is not required. For example, assuming that no other referential constraints from other tables refer to column pk, then it is valid to submit the following statement without the CASCADE CONSTRAINTS clause:
ALTER TABLE t1 DROP (pk, fk, c1);

Renaming columns in 8i

I have tried in vain to rename a column in 8i. There are no good examples out there. Here's my code
SQL> DESC KKQA_CLINIC_CD
Name Null? Type
CLINIC_CD NOT NULL VARCHAR2(15)
REC_EFFENDDT NOT NULL DATE
REC_EFFDT NOT NULL DATE
IDX_NM VARCHAR2(60)
DEPT VARCHAR2(30)
SUBDEPT VARCHAR2(30)
CLINIC_CD_DESC VARCHAR2(150)
MIM_CODES_CLINIC VARCHAR2(1)
HOSPITAL_BASED VARCHAR2(15)
REG_SOURCE VARCHAR2(15)
SQL> ALTER TABLE KKQA_CLINIC_CD ADD (CLINIC_CD_EFFENDDT DATE);
Table altered.
SQL> UPDATE KKQA_CLINIC_CD SET CLINIC_CD_EFFENDDT=REC_EFFENDDT;
0 rows updated.
A second attempt to rename another col, yeilds error:
ALTER TABLE KKQA_CLINIC_CD SET CLINIC_CD_EFFDT=REC_EFFDT
ERROR at line 1:
ORA-02000: missing UNUSED keyword
I just can't seem to find any meaningful examples or substance on this problem particularly ora-02000
I have tried the "unused" keyword example, it basically deletes a col. Can someone help, I am thoroughly puzzled.

Renaming a column is not supported in 8i.

Renaming columns resulting in breakage of already existing reports

Hi
We recently upgraded from 10g to 11g and we faced the following issue related to trailing spaces:
In 10g we had trailing spaces for few columns which accounts for say around 300 in number. After consistency check, these trailing spaces were shown as warnings in 10g and did not error out any reports. But in 11g, these trailing spaces were shown as errors and resulting in the breakage of already existing reports. To avoid this, we have to delete the trailing spaces along with the aliases. After this, the only process we are aware of, is to re-pull the renamed columns in the existing reports to make them error free. Now we have around 200 reports using these columns and it requires good amount of manual effort to go in. I would like to know, is there any better solution other than re-pulling these columns to keep the reports error free.
Any suggestions on this will be very helpful and greatly appreciated.
Thanks

Rename columns

Hi
As input I use an Excel file with ONE worksheet and columns C1old, C2old, C3old...
As output I use an Excel file with MORE worksheets W1, W2, W3...and columns W1_C1new, W1_C2new, W1_C3new...in worksheet W1, W2_C1new, W2_C2new, W2_C3new...in worksheet W2 and so on.
In MS-SQL I have a table with 2 columns doing such mapping (renaming):
C1old    W1_C1new
C2old    W1_C2new
C3old    W1_C3new
C4old    W2_C1new
C5old    W2_C2new
How to implement it in SSIS?
If it's too difficult I better write a macro (VBA) to simply rename columns and put them on the right worksheets according to the MS-SQL table.
Thanks a lot!

Rename column name

Can i rename column name of a table. If so how to do it????

before 9i
Renaming a column in table:
==========================
This is possible by updating the "name" column of the col$. To reflect this
change in the system views, run catalog.sql and catproc.sql.
Here is an example:
SQL> create table test(
x number,
y varchar2(10),
z varchar2(10));
SQL> insert into test values (12,'Child','BLUE');
SQL> insert into test values (34,'Mens','BROWN');
If you wanted to rename column "x" as column "x1" then do the following.
The first step is to identify the object number for the table (as SYS):
SQL> select obj# from obj$
where name='TEST' and owner#=9;
OBJ#
======
58217
Now identify the column numbers for the table:
SQL> select obj#, col#, name from col$ where obj#=58217;
OBJ# COL# NAME
58217 1 X
58217 2 Y
58217 3 Z
To change the name, a simple update statement will suffice:
update col$ set name='X1'
where obj#=58217 and col#=1;
To reflect the change in system views, run catalog and catproc (unix) eg:
svrmgr> @$ORACLE_HOME/rdbms/admin/catalog
svrmgr> @$ORACLE_HOME/rdbms/admin/catproc
Now when a describe of the table is done:
SQL> desc test;
Name Null ? Type
X1 NUMBER
Y VARCHAR2(10)
Z VARCHAR2(10)
Similarly, selecting from the table and querying views such as
DBA_TAB_COLUMNS shows the new column name.
NOTE: Before changing column names, drop any indexes,
foreign keys and primary constraints that might be on
the column. These can be re-created later.

Rename column !!

Can oracle 8i gives a facility to rename column ? How ?
Thanks in Adv.

Its a bit longer process but u can do it:
SELECT obj#
FROM sys.obj#
WHERE name = '<your_table_name>';
SELECT col#
FROM sys.col$
WHERE obj# = <obj# from the above query>
AND name = '<column_name>';
UPDATE sys.col$
SET name = '<new_column_name>'
WHERE obj# = <obj# used in the above query>
AND col# = <col# from the above query>;
It won't show the effect immediately. So use this:
ALTER SYSTEM FLUSH SHARED_POOL;
Now describe the table and find the new column name :)
Hope this helps.

Rename Column in Table

Hi
It's anyway to rename a column name in the Table name?
For info I using Oracle DB 9.2
regards
wisman

Under no circumstances should you change the data dictionary unless:[list=1]
[*]Oracle support tells you to;
[*]you really want to re-build your database.
[list]
Point 2 is not likely but it is a real possibility so take a full backup.
If you are on 8i the proper way to do it is this:[list=1]
[*]ALTER TABLE my_table ADD (new_name varchar2(10));
[*]UPDATE my_table SET new_name = old_name;
[*]ALTER TABLE my_table DROP COLUMN (old_name);
[list]
Obviously you'll need to handle integrity constraints, etc.
If you are on 9i you can do this:
ALTER TABLE my_table RENAME COLUMN old_name TO new_name;Cash back! APC
