We have some tables in our database in which for loading data we have the setup in place to do Exchange partition after data load into staging. Today we did changes to column length to one pair of main and staging table. Post that Exchange partition stop working.

Can i alter the table to create partition on non partition table, i have tried and could not create it. Do we have some other means to do it as this is the live table and cannot drop them else will lose the data.

i have a problem in my view. when i try to update a column in my view it prompts me with an error. i consulted the database error messages, and the description is as below:

Cause: An attempt was made to insert or update columns of a join view which
map to a non-key-preserved table.
Action: Modify the underlying base tables directly
i dont understand this "non-key-preserved table". is there any way out from this????. why cant i perform update opearation???. parent tables and the view are as follows:
(

View 3 Replies View RelatedI have a table with usernames and passwords. The passwords are stored in plaintext. I would like to issue an ALTER command on the password field to store a hash instead, and then repopulate those fields with an encrypted version of the plaintext passwords that were there before.
I would prefer to do this in a procedure, as I am going to perform it in a test environment first, then eventually in the production environment.

I want to find the max length for a column in oracle, without querying each of the columns. Are these stats stored somewhere?
I have several fields defined as varchar2(4000). Not all of them use up 4000. Instead of querying each one ..max(column name) i want to explore if there is a way, i can find the max size stored somewhere? dba_tab_cols provides size of the field. is there any table that provides max used so far?
create table test_schema(
col1 varchar2(50)
)
insert all

into test_schema values ('this_is_a_test_test')
into test_schema values ('this_is_a_test_test_xxxx')
into test_schema values ('this_is_a_test_test_aaaaaaaa')
select * from dual;
I want to get the length of the col1 value with maximum length of characters also with that field value.
i.e o/p is
this_is_a_test_test_aaaaaaaa length 28
how can I do it??

I think that performance better partition table than non-partition table. How to assure partition table is better than non-partition table at SELECT operation?
I have compare a specific query EXPLAIN PLAN at partition table and non-partition table. both tables data is same. Is it true way or not?
if one of the columns is given as
ABC varchar2(10)
the size of the data in bytes that this column going to hold.
I had a varchar2 variable which was storing some data and I could use the LENGTH function to get the length of the data. However, If I change it to CLOB. What is the best way to get the length?
v_clob_size:= (DBMS_LOB.getlength(v_clob)) / 1024 / 1024;
DBMS_OUTPUT.put_line('CLOB Size ' || v_clob_size);
another one is
LENGTHB(TO_CHAR(SUBSTR(<clob-column>,1,4000))) But this seems restricted to first 4000 characters only.
i want to add a column data of datatype number of all the tables at a time in a database..

is there any way we can find out which row is updated in oracle table if we don't have any date/time column in table.
let say.
Create table T1 (ename varchar2(200), age number);
insert into T1 values ('A',20);
insert into T1 values ('B',30);
insert into T1 values ('C',40);
insert into T1 values ('D',50);
commit;
update t1 set age=50 where ename='A'
commit;
looking some oracle query which identify which record is update in table in given time period.
I have a table that partitioned into six partitions. each partitions placed in different table space and every two table space placed it on a different hardisk
when I will do query select with the non-partition keys condition, how the search process ? whether the sequence (scan sequentially from partition 1 to partition 6) or partition in a hardisk is accessed at the same time with other partition in other hardisk. ( in the image, partition 1,4 accessed at the same time with partition 2,5 and 3,6)
I am using 11.2.0.3.0 version of oracle.
Now we are supposed to apply column level TDE to some of our table in database. Now it will be a 'ALTER' on the columns. it involves 4 big tables out of which 3 tables having size ~30GB(one is partitioned table) and another one ~800GB(Not partitioned) Now the concern is, what will be the efficient/safest way to apply TDE on columns, below are the two options with us. (NOTE - We do have downtime window during DB maintenance but looking at the size of the table, i suspect it might take lot.)
1. Directly apply 'ALTER' on the columns. (Note- i was testing on my local, it took 3hrs for a 30GB table to ALTER the column to TDE)
2. Use Table Redefinition for Altering the column. (Creating interim table with column as TDE and then Redefining whole table).
We are running an Oracle 10g server.
We are adding support for barcode scanner in one part of our information system. So that the mechanics can add parts to an work orders bill of material themselves using barcode scanner to scan the part and enter the qty.
I can via SQL add a part to the bill of materials and reserve the part. But then the part needs to be issued to make it disappear from the stock.
I have found a table that contains information about the part and the bill of material, it has a column named "QTY ISSUED" I have tried via an update command to set the qty issued = 1 for the reserved part. The table is updated, and via SQL everything looks fine, but the part doesn't disappear from the stock. So my guess is that there is a trigger or function somewhere that I need for this.
How can we partition a table based on date if it does not have a date column.
Actually I have to compare two tables on daily basis and fetch few rows from those two tables and enter it to a third table.But both these tables does not have a date column.
I am confused if i need to alter those tables and add date column or if there is some way in which i can compare the data from the two tables for that particular day only and not the whole table data.
