Modify columns in partition

Dear all,
CREATE INDEX CMLS.SUPRT_N1 ON CMLS.SUPERT
(LNO, C_DATE, TDATE, TRF_GP, CNO,
CTYPE, CTYPE)
TABLESPACE CMDK01
INITRANS 2

TABLESPACE CMDK01
PCTFREE 10
INITRANS 2
MAXTRANS 255
STORAGE (
INITIAL 6M
MINEXTENTS 1
MAXEXTENTS UNLIMITED
BUFFER_POOL DEFAULT
I want to modify the index to remove the column c_date and look like
CREATE INDEX CMLS.SUPRT_N1 ON CMLS.SUPERT
(LNO, C_DATE, TDATE, TRF_GP, CNO,
CTYPE, CTYPE)
TABLESPACE CMDK01

MAXTRANS 255
STORAGE (
INITIAL 6M
MINEXTENTS 1
MAXEXTENTS UNLIMITED
BUFFER_POOL DEFAULT
Do I have to drop the index and recreate it? or shall I modify it ?. if so, can anyone let me know the command used ?
Kai

You forgot to remove C_DATE in you second example ;-)
And someonelse answered your question already

Table with BLOB column re-partitioning

Currently I have a table with a blob column Z partitioned on Column X I want to re-partition the table on Column Y is there a quick way of doing this.
INSERT INTO SELECT * has limitations on the blob size I guess.
Can someone explain this?

I am using hash partitioning looks like split partition doesn't apply for hash partition:
"The SPLIT PARTITION clause of the ALTER TABLE or ALTER INDEX statement is used to redistribute the contents of a partition into two new partitions. Consider doing this when a partition becomes too large and causes backup, recovery, or maintenance operations to take a long time to complete. You can also use the SPLIT PARTITION clause to redistribute the I/O load.
This clause cannot be used for hash partitions or subpartitions."

Finder Window - Date Modified Column Keeps Changing

When I open a Finder window, change the size of the "Date Modified" column then close the Finder window, the next time I open the same Finder window, the "Date Modified" column will compress the size of the column.
Why isn't Finder 10.9 maintaining my column changes?
Any assitance or insight whould be appreciated.

I solved the scrunched Date Modified column header in a similar fashion but added the Date Added field, which fixed the width of both Date columns.
After doing so, I now find both Date-oriented columns display and read dynamically the actual date and time.
I'm now looking for a solution to that issue, explained here:
finder window date added date modified show date time always

Virtual column based partitioning

Hi,
we have a non-partitioned table in a production database and wish to partition it based on an expression. Since we are on 11.2 the first thing that comes to mind is virtual column based partitioning. The "problem" is that in order to partition by a virtual column, you have to create one, and adding a new column to a table could break any application that doesn't reference the existing columns by name, e.g. "SELECT *" or. "INSERT INTO table VALUES(....)".
My question is: is it possible to somehow specify the expression on which to partition directly in the "partition by" clause rather than specifying it as a virtual column definition?
Example:
Instead of this..
SQL> create table test (
2    id             number not null,
3    content        varchar2(10),
4    record_type    varchar2(1) generated always as (case when (substr(content, 1, 1)='B' and not substr(content, 1, 3)='Bxy') then 'B' else 'A' end) virtual
5 )
6 partition by list(record_type)
7 (
8    partition partA values ('A'),
9    partition partB values ('B')
10 );
Table created...I'd like to use something like this:
SQL> create table test (
2    id             number not null,
3    content        varchar2(10)
4 )
5 partition by list((case when (substr(content, 1, 1)='B' and not substr(content, 1, 3)='Bxy') then 'B' else 'A' end))
6 (
7    partition partA values ('A'),
8    partition partB values ('B')
9 );
partition by list((case when (substr(content, 1, 1)='B' and not substr(content, 1, 3)='Bxy') then 'B' else 'A' end))
ERROR at line 5:
ORA-00904: : invalid identifierThank you in advance for any answers.

Jure

adding a new column to a table could break any application that doesn't reference the existing columns by name, e.g. "SELECT *" or. "INSERT INTO table VALUES(....)". "Ok, i got it. You mean, in application you are using select * from yourtable; and those data is being used by a datagrid or any control, then where that application will show / handle the new column data right ?
Yes, thats why DBA and developers do SDLC (Software Development Life Cycle); that our table will be looks like this, these will be columns, these will be their data types, these will be followed in naming convention, privileges, indexes, storage parameters, constraints, dependent objects etc. Now after creating the table, you found a need to add a column, it means there was some lapses happened at the design time/phase or business requirements are newly defined.
So, as far as concerned of select * ... ; you have to change in the application by :
select col1, col2, new_col from your table... (as per order of your datagrid control columns). There is no other solution, you have to change in application code at every place where you have used select * and if those statements are being merged / deals into a control)
New column addition will hamper only at select * from... not with any INSERT/UPDATE/DELETE, because if they are running fine it means, they have well written column references. For DMLs you need not worry so far.
By the way, what is your technology for application ? I have worked on couple of applications in ASP.NET with using datagrid which auto add/removes the columns in itself as per cursor result (not rememberring the exact property of it though)

Items "date modified" column when viewing files as list in finder

I'm not really sure if I can change this viewing option, but i will give it a try:
when viewing files as list in finder, "yesterday" items "date modified" column shows up with the term "yesterday", while this does not happen for "today" items, where what shows up is just today's date and not the term "today".
I found this rather confusing, since it is not immediate: i.e. if I want to check for items modified today at a glance, i need to pick today's date from a ist with a number of different dates. As a matter of fact, it's a way easier when checking for yesterday's items.
Suggestions anyone?
Thanks!

Manage Table / Modify column does not display current values

Hi,
when I choose "Modify column" from the menu "Manage table", the current properties of the column, i.e. type, size and so on, are not shown, but are defaulted to whatever value has been defined inside that page, so the column type is always set to "Number" for instance.
It would be definitely better to retain the current values, in my humble opinion.
Bye,
Flavio

I have also run into this problem. I am running IQ 16.0 sp1. I wanted to increase the number of characters in one of the columns so I have to create a new column, copy the data, delete the old column then rename the new column.
Is there any reason the MODIFY function is not implemented in IQ?

Modifying a Range Partition

Hi! Guys
I have a table partitioned by a date column.. My current highest partition is:
SPSWEEK14 VALUES LESS THAN (TO_DATE(' 2008-02-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
How can I modify this partition to 2008-04-01?
Thanks in advance
Babu Yalamanchi
P.S. We are using Oracle 9.2

I dont think so, we can not modify range of any partition. What I suggest here is we can add partition and then merge that partition with higher value, So at the end you will get one partition with higher value. But make sure to take care of invalid index and all that.

How to add new column in partition table

Hi,
In Oracle 10g Database, I have one table (X) with list partition . I have added one new column to "X" by "Alter Table" command. Please advise whether any other command needs to be executed since it is a partition table .
The "X" table is used for partition swapping with another table (Y). I have added the same column also in table "Y". Will there be any issue while swapping the partion with the following command
alter table X exchange partition partition_name with table Y
Version Details :
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 OS
Solaris 5.10
Thanks in advance

you would have to explicitly put that into the create table as select - the partition details.

Problem with a 2 columns Range Partitioning for a indexed organized table

have an indexed organized table with a 2 column PK. the first field (datum) is a date field the second field (installatieid) is a number(2) field.
Every minute a 7 records are inserted (installatieid 0-6).
I like to partition this table with one partition per year per installatieid.
I tried to do it with:
partition by range(datum,installatieid)
(partition P_2004_0 values less than (to_date('2004-01,'yyyy-mm'),1)
,partition P_2004_6 values less than (to_date('2004-01','yyyy-mm'),7)
partition P_2005_0 values less than (to_date('2005-01','yyyy-mm'),1)
,partition P_2005_6 values less than (to_date('2005-01','yyyy-mm'),7)
but now only the P_2004_0 and P_2005_0 are filled.
I thought about to combine a range partition on datum with a list subpartition on installatieid, but I read this is not allowed with an index organized table.
How can I solve this problem.

partition by range(datum,installatieid)
(partition P_2004_0 values less than
(to_date('2004-01,'yyyy-mm'))
,partition P_2004_6 values less than
(to_date('2004-07','yyyy-mm'))
partition P_2005_0 values less than
(to_date('2005-01','yyyy-mm'))
,partition P_2005_6 values less than
(to_date('2005-07','yyyy-mm'))
? Sorry haven't got time to test it this morning ;0)

Can't modify column?

Hi,
I need to alter the data type of a date column to varchar2(6).
Here's the tabel I need to change.
SQL> desc foo
Name Null? Type
PK NUMBER
DOB DATE
I understand that I must NULL out the DOB column before I can do the ...
alter table foo modify (DOB varchar2(6));
... so I create another table like so ...
SQL> create table foo2 as select * from foo;
Table created.
... now I can do ...
SQL> update foo set DOB = NULL;
100 rows updated.
SQL> commit;
Commit complete.
... now I do ...
SQL> alter table foo modify ( dob varchar2(6));
alter table foo modify ( dob varchar2(6))
ERROR at line 1:
ORA-01401: inserted value too large for column
Why do I get this error?
thanks

Depending too regarding the nls_date_format in your system, the result when you query the date will be higher o viceversa.
As you realized try with varchar2(8), if it fails try
to increase that number.

Hi,
I think that internally, Oracle understand that NUMBER is a synonym for NUMBER(38).
The precision can range from 1 to 38. Then, that's why this error is happening;
You can try this below:
SGMS@ORACLE10> create table x (cod number);
Table created.
SGMS@ORACLE10> insert into x values (1000);
1 row created.
SGMS@ORACLE10> commit;
Commit complete.
SGMS@ORACLE10> desc x
Name Null? Type
COD NUMBER
SGMS@ORACLE10> alter table x add (temp number);
Table altered.
SGMS@ORACLE10> update x set temp = cod;
1 row updated.
SGMS@ORACLE10> update x set cod = null;
1 row updated.
SGMS@ORACLE10> alter table x modify cod number (10,0);
Table altered.
SGMS@ORACLE10> update x set cod = temp;
1 row updated.
SGMS@ORACLE10> alter table x drop column temp;
Table altered.
SGMS@ORACLE10> desc x
Name Null? Type
COD NUMBER(10)

Modify column in an internal table

Hi Friends,
I have an internal table itab1 which has a column called zpo_number .
I am getting the PO from a BAPI call storing in a field w_ponumber.
I have the code below . THe table itab1 has rows all having the same matnr .
How can I modify all the rows of the table with the same w_ponumber ?
Thanks!
Loop at itab1
babpi call get po number
w_ponumber.
MODIFY itab1
endloop.

simplicity change to your original code provided:
Loop at itab1
babpi call get po number
w_ponumber.
itab1-z_ponumber = w_ponumber.
MODIFY itab1
endloop.
Or -
Loop at itab1
babpi call get po number
itab1-z_ponumber.
MODIFY itab1
endloop.

Thanks for your quick reply....
I have already checked and included in my example given.
SQL> SELECT * FROM DBA_PART_KEY_COLUMNS WHERE OWNER='SCOTT';

SCOTT      SALES_RANGE     TABLE TIME_ID                       1It's only giving the column name on which partitioning is done, not the partitioning condition.
My question was, in which table i can check the criteria on which i have range partitioned a table ? Is there an dictionary table which holds information like:
PARTITION_NAME     PARTITION_CONDITION
SALES_Q1_2012       VALUES LESS THAN (TO_DATE('01-APR-2012','dd-MON-yyyy')I hope i am clear in my question......

Virtual column and partition exchange load

Hi All,
Can someone tell me that if i have a virtual column on a table in 11g then can we load the data as partition exchange loading into the table.
Thanks & Regards,
Ankit Rana

Why not run a simple test with a dummy table, a few columns (plus a virtual column) and a few partitions ?
Excellent suggestion.
Shouldn't take more than about 30 minutes to create a test case - and if it takes more than 30 minutes the OP needs the practice anyway to get a better feel for the technology.
Hint to OP: make sure you put some data in the "incoming" table, make sure you put some data in the "non-exchanged" partitions, remember to include a unique/pk constraint if you're expecting one on production, and run with sql_trace enabled to see what's happening in the background.

end RenameColumn;
Once you have the above in and compiled okay then you can rename you column names by:
begin
RenameColumn('SCOTT', 'EMPTEST', 'SAL', 'SALARY');
end;
also while still connected as SYS, note the parameters SCOTT should be the schema owner which contains the table, EMPTEST is the table name which contains the column, SAL is the old column name and SALARY is the new column name.
Have fun.
