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 use a sequence to generate an alphanumeric code and I need to update all rows of a table with that sequence. The sequence is created with this code:
SELECT (CHR(TRUNC(s.nextval/1000) + ASCII('A')) || LTRIM(TO_CHAR(MOD(s.currval,1000),'099'))
FROM dual;
I have tried many things - most recently
Update t3_temp_table
SET mergecode =
SELECT (CHR(TRUNC(s.nextval/1000) + ASCII('A')) || LTRIM(TO_CHAR(MOD(s.currval,1000),'099'))
FROM dual;
I get missing expression error.
It works fine if I use a straight s.nextval

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).

I am facing some challenge while running update query on newly added column in existing table.
Environment Details
Oracle 9i, version 9.2.0.6
Os Unix Aix 6.1
No of records in table : 12572770
Below are the step i followed.
1. In table testtablename, I have added new column COLUMNNAME29 with datatype VARCHAR2(8).
2. After adding the new column, i executed the update query to populate the data form COLUMNNAME1 to COLUMNNAME29.
3. The query is executed using COLUMNNAME24 in where clause, to drive query in index based.
SQL> desc testtablename
Name Null? Type
----------------------------------------- -------- ----------------------------
COLUMNNAME1 VARCHAR2(8)
COLUMNNAME2 CHAR(1)
COLUMNNAME3 CHAR(1)
COLUMNNAME4 VARCHAR2(8)
COLUMNNAME5 VARCHAR2(11)
[Code]...
Table altered.
SQL> select index_name, column_position, column_name from dba_ind_columns where table_name = 'TESTTABLENAME' order by index_name,column_position;
INDEX_NAME COLUMN_POSITION COLUMN_NAME
------------------------------ --------------- --------------------------------------------------
IDX_TESTTABLENAME 1 COLUMNNAME24
Problem faced & My analysis
1. The update query is hanging in database, it's not progressing (In single update, approximately 40000 records will get update)
2. No oracle error thrown in alert log or in session where the query being executed.
3. The event for the query is "db file sequential read".
4. When i update the newly added column COLUMNNAME29 with static value "1", the update completed successfully in few seconds.
5. Then i changed the static value to "1111" and executed the update statement, which result to query hanging in database.
6. I tried to update the existing column(COLUMNNAME1) in table with static value "1111", the update completed successfully.
Below are the queries completed successfully
Update Testtablename
Set Columnname29 = '1'
Where Columnname24 >= To_Date('01-12-2002 00:00:00', 'DD-MM-YYYY HH24:MI:SS' )
And Columnname24 < To_Date('01-01-2003 00:00:00', 'DD-MM-YYYY HH24:MI:SS')

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 || ')';
--For example:
-- alter table XXX modify NEW_COL varchar2(20)
execute immediate vSTATEMENT;
exception
...
end;

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;
BTW, I did try to preview message, and then click on Create Topic, it gave me error..again.

how to play around with NDS dynamic sql and I'm trying to add a column on the fly.Basically the procedure is trying to take a table name, column name, and eventually a data type and adds it to a table.
It works fine without the bind variable for the column name, accepting the table name on the fly.As soon as it tries to use the column name I get an ORA-00904 invalid identifier exception.
Here is the procedure I'm using
CODEcreate or replace
procedure test(tbl_name varchar2, col_name varchar2) IS
qry varchar2(500);
begin

Here is how I'm executing it.
CODEexecute test(tbl_name => 'BB_SHOPPER', col_name => 'MEMEBER');
