I got a couple of reports that are made as .CSV files from PL/SQL. However I am lacking some design features. Is it possible to define text + background color and height + width of fields? (I am using utl_file package.)
View 4 Replies View RelatedIf you were asked to design a schema, would you create a table (however irrelevant) without a primary Key ? Say for example, a 'non-business' table like an Error logging table which logs exceptions thrown from stored procedures, would you create this table without a primary key ?

View 19 Replies View RelatedLet us say I want to audit data updates, deletes on existing table EMP_TAB that has a few hundred thousands of records.I created a shadow table Emp_tab_audit and added few audit columns
Emp_tab (
Empno NUMBER NOT NULL,
Ename VARCHAR2(10),
Job VARCHAR2(9),
[code]...
I am mostly interested in UPDATES and DELETES but I decided to add INSERTS to have full history for each eomplyee in one table (audit schema) instead of querying two tables all the time (production table and audit table) to see the changes.
I created this AFTER INSERT, UPDATE, DELETE trigger.decided to copy the :NEW values for INSERT and UPDATE and :OLD values for DELETE. attached.
so when insert happens, the first audit row is created in EMP_TAB_AUDIT. update happens, the 2nd new row is created in EMP_TAB_AUDIT.
The problem I am facing is the old records that curently exist. If someone updates an old row I am copying the :NEW values so I won't have a copy of the :OLD values unless I create 2 ROWS (one for the old and one for the new).
Do you think I should copy all the hundreds of thousands of records to the AUDIT tables for this to work.

View 1 Replies View RelatedI am designing a database as a practice exercise, but have come across a problem.
Here is my design:
Branch Manager Employee
------- ---------- ----------
BranchID ---- ManagerID |---- EmpoyeeID
... | EmployeeID ---- ...
Manager ---- EmployeeIDOfManager
...
Branch
Note: The ... in the tables are just placements symbolizing that there are multiple irrelevant (to this thread) fields.
The problem is with the field highlighted in italics whilst the primary keys are in bold. I need to somehow retrieve that ID, but I can't create a many-to-many relationship.

Requirement - I have several banks as clients globally, like HSBC, RBS, AMEX etc. Each bank operate globally, and are divided like the geographies, regions etc. For eg. HSBC is operating from US, UK, ASIA, AUSTRALIA. Each geoagraphy is further divided/childs, like, in ASIA has INDIA, PAKISTAN, SRI LANKA, CHINA. Further, it is divided, like in India, it has cities like DELHI, BOMBAY, CHENNAI etc., then further it has within Delhi - Lajpat Nagar, Rohini, Pashim Vihar etc.
As per the above scenario, I need to store addresses, phone numbers, of all the branches of all clients. Also, there is one more condition like in the above defined hierarchy, later on, a new hierarchy can be added, like In INDIA, it can further divided in States and then its local cities.

View 2 Replies View RelatedI am trying to drop 90 columns from a big partitioned table. I was trying a physical drop first and since it is taking longer time I decided make the columns unused state and drop them. However I was able to set them to unused state.
Now I am trying to drop those unused columns from the table, it is running since 22hours Apporox. I am keep increasing the undo tablespace to retain the undo data.
I also have decreased the undo_retention to 300 from 900.
My question is there any better way to drop these columns. And is there any way to flush out the data from undo.
I have a quick question about Automatic Memory Management in 11g. I know that it combines the SGA and PGA components together, but the pga_aggregate_target (in 10g) was a target, rather than a strict limit. In certain circumstances you could (and we have) exceed the pga_ aggregate_ target by quite some way.
If I use AMM, does this enforce a limit on the PGA usage – or if I through enough bind variables at it, can I still exceed the ‘target’?
I just wanted to know if removing access for management and tuning packs in OEM disbale its access in just enterprise manager or in the database as well, i mean would that disable access to the scripts in the rdbms.admin driectory as well.

Question1. From googling , I gather that ASSM ( Automatic Segment Space Management ) is a new method used by Oracle to manage space inside data block. If this is the case, then it should have been named 'Automatic Block Space management' . Right ?
Question2.What was the most notable advantage in your opinion in using ASSM as opposed Manual Segment space management ?
what is difference between san and asm because san also provide mirroring like asm,why we should go for asm.
