We want all the line breaks to replaced with a space or a comma. to implement this i have used to simple select as :
Select Replace(text,chr(10),'')
From paymemo
where referencepkey = (select pkey from paymain where ID = 'DED-520074 505354DN6 2012-02-04 00:06:48');
This is not working because of type conversion issues.

Customer is sending data from legacy system (Source) with the web service which in turn calls a package lying on Oracle server (Target). Now this package is simply inserting data passed by legacy system into master staging table in Oracle database. When they started this process in Sept 2011 then 4 lack records were inserted into staging table. In Oct 11 it was 0 records Nov 11 it was 2 lack records, Dec 11 it was 1 lack records, in Jan 12 it was 1 lac records, Feb 12 73k records, Mar 12 0 records, Apr 12 52k records.
As we see that number of records inserted in the table got reduced with time.. what should be the starting point here since web service is calling that package on the fly, how can i enable trace for that package? I cannot replicate this is Dev as this process is only working in PROD.

I got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.
I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?
1)Stop SQL apply
2)Apply patches on logical standby database
3)let the name server point to the backup site
4)Apply patches on the primary database
5)Start SQL apply
6)Let the name server point back to the production site

I have got a procedure that successfully creates an oracle external table and populates it with the contents of a file. This works fine until I have a situation where one of the fields is a VARCHAR2(2) and I try to insert say, a 5 character value. When this happens the record in question does not get populated in the external table (and rightly so), but I could do with working out if there is a discrepancy in the number of records in the file and the number of records that actually make it into the table so I could inform the user that there is a problem.
I have attached the code that creates the external table and populates it.

I have external file like (.csv or .txt) which contain million of record...i wnat to upload it in backend by using form 6i/10g.
by using package text_io.fopen i read it and by using for..loop conventional method insert record into table...but it will take time..
Is there any way like we use bulk collect and FORALL in backend for inserting data into table..
Is there any way to read external file at a time and insert it ...so minimize inserting time....process will become fast.

Encountering an issue with an Oracle external table. We get the following error when we load a particular file in this table:
ORA-12801: error signaled in parallel query server P000
ORA-29913: error in executing ODCIEXTTABLEFETCH callout
ORA-30653: reject limit reached
ORA-06512: at "SYS.ORACLE_LOADER", line 52
We have narrowed this down to a text field in the file that contains the following text (text obfuscated):
XXXXXXXX ł XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
This is nominally 40 characters long, which matches the maximum field size, but it is being rejected because it appears the 'ł' character is causing Oracle to interpret the length as 41 characters instead. If I remove a X then the file loads without issue.
We tried this in a new schema we created where we added the same table and used the same file. There was no problem at all. The oracle database has the following settings:
NLS_CHARACTERSETUTF8
NLS_NCHAR_CHARACTERSETUTF8
NLS_LENGTH_SEMANTICSBYTE
NLS_LANGUAGEAMERICAN
The table is defined as follows:
CREATE TABLE XXXXXXXXXXXXXXXXXXXXXX.XXXXXXXXX_INTERFACE
(
XXXXXXXXXXXXXXXXXXXX VARCHAR2(40 CHAR),
XXXXXXXXXX VARCHAR2(40 CHAR),
XXXXXXXXXXXXXXXXX VARCHAR2(40 CHAR),
XXXXXXXXXXXXX VARCHAR2(40 CHAR),
[code]........
We tried adding the following attributes but they did not seem to make any difference:
CHARACTERSET UTF8
STRING SIZES ARE IN CHARACTERS

In the article regarding gathering CBO Statistics, it states: QUOTE When an Oracle database is created, a job will be scheduled that will generate the database statistics for you. You will still need to collect system statistics however, as these are not collected by the automatic statistics gathering mechanism.
what is the difference between "database statistics" and "system statistics"? In other words, do I need to run this script for each schema owner in my 10g/11g instance?
variable whoami varchar2(20);
begin
select user into :whoami from dual;
end;
exec dbms_stats.gather_schema_stats( -
ownname => :whoami, -
options => 'GATHER AUTO', -
estimate_percent => 15, -
cascade => true).
