I am abolute new in PL SQL and I am working on following topic:
I have to check if an entry exists in a table.
- if it exists ...... do something
- if not ...... simply go on
I tried the following:
select Count(*)from products p
where p.productNbr = temp_Nbr
Group By t.produkt;
I fetched the result into a variable entries
if entries > 0 .....
MY problem is the following:
If there are entries (entries>0) --> it works
If there are no entries, entries is not 0 but 'no data found' --> crash
I cannot work with Exceptions because this all happens in a Loop which must go on in both cases!

I had created a new table named USERLOG with two fields from a previous VIEW. The table already consist of about 9000 records. The two fields taken from the VIEW, i.e. weblog_views consist of IP (consists of IP address), and WEB_LINK (consists of URL). This is the code I used,
CREATE TABLE USERLOG
AS
SELECT C_IP, WEB_LINK FROM weblog_views;
I want to add another column to this table called the USER_ID, which would consists of a sequence starting with 1 to 9000 records to create a unique id for each existing rows. I'm using Oracle SQL Developer: ODMiner version 3.0.04. I tried using the AUTO-INCREMENT option,
ALTER TABLE USERLOG
ADD USER_ID INT UNSIGNED NOT NULL AUTO_INCREMENT;
But I get an error with this,

I recently started working with legacy code and noticed that some huge tables (5 years worth of data, don't have more details on me right now but can post later if needed) are partitioned based on time sequence number column while majority of queries are done based on time (different column). Queries performance is degrading and I'd like to try to modify partitioning and run some tests to evaluate performance improvement.
My only concern is with so much live data I have to come up with solution on how to switch partitioning with the least impact on applications running 24 x 7. Something you have done in the same situation and it worked?

I am trying to partition an existing table through DBMS_REDEFNITION. Following are the steps that I have taken and the error I have got.
1. Creating a table to be partitioned.
CREATE TABLE SO33070_ORIGINAL
(
SERIAL_ID NUMBER(15,0),
INSERTED_TIME DATE DEFAULT SYSDATE,
PRIMARY KEY (SERIAL_ID)
);
Success
2. Checking if the table can be partitioned
DECLARE
v_name VARCHAR2(256);
BEGIN
SELECT sys_context('userenv', 'current_user') INTO v_name FROM dual;
DBMS_REDEFINITION.CAN_REDEF_TABLE(v_name, 'SO33070_ORIGINAL', dbms_redefinition.CONS_USE_ROWID);
END;
Success
3. Creating a duplicate table
CREATE TABLE SO33070_NEW
(
SERIAL_ID NUMBER(15,0),
INSERTED_TIME DATE DEFAULT SYSDATE
)
PARTITION BY RANGE ("INSERTED_TIME") INTERVAL (NUMTODSINTERVAL(1,'DAY'))
(
PARTITION "p1_1" VALUES LESS THAN (TO_DATE(' 2012-01-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
)
Success
4. Starting the redefnition process
EXEC DBMS_REDEFINITION.START_REDEF_TABLE( uname => 'CDS_USER', orig_table => 'SO33070_ORIGINAL', int_table => 'SO33070_NEW', col_mapping => '', options_flag => DBMS_REDEFINITION.CONS_USE_ROWID);
Success
5. Copying the dependents
DECLARE

BEGIN
DBMS_REDEFINITION.COPY_TABLE_DEPENDENTS(
uname => 'CDS_USER',
orig_table=>'SO33070_ORIGINAL',
