I 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 have a table PR in that some data is there for instance, My Mr_NO was Char(11) I modify MR_No to Char(13)My Table Structure now is:

I want to add two 00 after alter the table I want my result data like APN0000209085.I am updating through this command
update PR set Substr(MR_No,4,2)='00'

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).
what is the the use of views and synonyms if changes made to them affects the original table contents?It is data insecurity know?

I created a DDL trigger which manipulates columns of a table after an "alter table" statement.
For us this was all the time
"alter table XXX add NEW_COL varchar2(20)"
or
"alter table XXX modify NEW_COL varchar2(20)".
Unfortunatly we have now a requirement which statements "alter table XXX drop NEW_COL varchar2(20)".
My trigger works fine - you see no problem directly after statement execution but the table is then in an invalid status.
The connection will be destroyed after you tried to see the data of this table.
Also the export (creating a dump) will not work.
The problem I see is that I the database will do a "modify" on a column which has internal the status "dropped".
How I can get the information what kind of alter table statement will be executed?
Or is there any chance to select only columns from USER_TAB_COLUMNS without the "dropped" flag?
create or replace trigger TRIGGER
after alter
on SCHEMA
declare
vCharSet NLS_DATABASE_PARAMETERS.VALUE%TYPE;
begin
-- Select all columns of a table
select COLUMN_NAME, DATA_TYPE, DATA_LENGTH
from USER_TAB_COLUMNS
where TABLE_NAME = vTABLE_NAME; ...
-- Loop for all columns from our select
...
vSTATEMENT := 'alter table ' || vTABLE_NAME || ' modify ' || VOBJECTREC.COLUMN_NAME || ' ' || VOBJECTREC.DATA_TYPE || '(' || vNEW_DATA_LENGTH || ')';

-- alter table XXX modify NEW_COL varchar2(20)

I altered existing table EVENT_SUB - added 3 columns. After that, I noticed all the procedures which had mention of this table name went in INVALID status, even if its simple SELECT, ALTER OR INSERT as shown below..
SELECT * FROM EVENT_SUB
OR
INSERT INTO EVENT_SUB...
OR
ALTER TABLE EVENT_SUB
WHERE....
So I had to recompile all the procedures associated with it. Is there any other ways to achieve this, like a line of code to add in the procedure itself, right after this DDL statements.
Sometimes i use this:
select object_name, object_type from all_objects where owner='TOYCOM' and status='INVALID'
Then, I would simply recompile the invalid objects.
For indexes, i do...
alter index <name> rebuild;

I am developing some automated test packages for my PL/SQL Packaged code. Going forward I can code the test package in conjunction with the code but I have some historic packages that I would like to develop these test packages for.
To save time I would like to employ oracle data dictionary views in order to construct the framework for my test package. This includes using SQL to get a list of procedures / functions within the package in order to create the test procedures (spec and body). I can do this in a basic way using the user_procedure view with something like...
SELECT 'PROCEDURE test_' || LOWER(procedure_name)
|| ' (p_result OUT VARCHAR2 IS BEGIN JTA.ACCOUNT_PROFILE_MAINT.' || procedure_name || ' END '
|| LOWER(procedure_name) || ';'
FROM user_procedures WHERE object_name = 'ACCOUNT_PROFILE_MAINT' AND subprogram_id != 0 ORDER BY subprogram_id;
However, the above only really works (in simplistic form.. without parameters) for procedures within the package. I would also like to be able to determine if the procedure listed is actually a function or procedure (so that I can alter the syntax accordingly to generate a correctly formatted string calling the program unit).
So, initially how do I determine the type of package program unit I have (Proc/Function)? Do I need to go to all_source to get this information or are there other views available I can join to?
Eventually I would like to extend this to be able to automatically include any parameters in the generated calling string.. again, is there any other option apart from all_source to get this information?
I want to see a stored procedure definition which is inside the body of a package and the package is wrapped.So I am not able to see the content of the package body.I am new to oracle and I don't know how to decrypt the wrapped package.how to read the content of a wrapped package inside oracle.
