I am trying to migrate a table to a new table that has the field sequence changed and also has a new field added. My main question is if it is possible to have datapump add values to the new field in the target table.For example:
-original table has fields a, b, d, c
-new table has fields b, c, d, a, e
I want to load the new table and also include adding values for field e. In this case, field e is a year field, so it should be loaded with '2012'..Does datapump have the ability to do this? Is reorganizing the fields going to cause me any problems? We are on oracle version 11.2.0.3

Is there a way to specify null in external tables loaded if specific column has no data in the external file(CSV) being loaded ?
the following situation, I have a directory named /dat/global/stock/ inside this i will get files named differently for example below.abcdef.112dfgrt.2......
Here i want to load this file one by one into the external tables and generate one more file based on some enrichment.
Step 1. Have to take first file and to load into the ext table.
Step 2. Enrichment
Step 3.File generation.

I am doing a simple test and need to populate a small table with some data.
My table looks like this:
SQL> desc clob_test
Name Null? Type

ID NUMBER(20)
C1 CLOB
I have a pipe delimited data file ID range 1-50000 and random characters with a length of 100-4000 bytes for the clob field.
My control file looks like this but I am guessing it is wrong:
LOAD DATA
INFILE 'clob_test.dat'
INTO TABLE CLOB_TEST
FIELDS TERMINATED BY '|'
TRAILING NULLCOLS
(
ID INTEGER EXTERNAL NULLIF (ID=BLANKS)

I am using Oracle 10g Data Pump Export utility expdp. What I am trying to do is to export a single schema, except for a certain partition P in table T.
I have tried:
expdp user/pass@db dumpfile=... logfile=... exclude=table:" = 'T:P' "
It doesn't work. The whole table T gets exported.
Is there a way to exclude partitions from schema mode export?
If not, is there a way I can achieve the same with DBMS_DATAPUMP API?

Imagine you have 100 schemas backed up (expdp) in a dumpfile and you want to import just one schema from that dumpfile in a DB. You can specify just that one schema you want using SCHEMAS parameter in the impdp. But things are not straightforward when you want use REMAP_SCHEMA.
Here is my scenario:
===================
I took the expdp dump of schemas A and B in one go. So, dumpfile has objects from both A and B.The dumpfile name is : schemas_AandB.dmpNow , I want to create schema C from A using REMAP_SCHEMA parameter
-- Putting each parameter in a separate line for readability
impdp PSTREF/PSTREF_123
DIRECTORY=ADET_EFX_DIR
DUMPFILE=schemas_AandB.dmp
LOGFILE=CreatingCfromA-Impdp.log
REMAP_SCHEMA=A:CEverything goes fine. Schema C is created from Schema A in the dumpfile.
But impdp is trying to create schema B as well because schema B was present in the dumpfile. Since the schema B and its objects are already in the DB , I get the following errors.
ORA-31684: Object type USER:"B" already exists
ORA-31684: Object type PROCEDURE:"B"."SP_CLEAREXPIREDSESSIONDATA" already exists
ORA-31684: Object type PROCEDURE:"B"."SP_DELETESESSIONDATA" already exists
ORA-31684: Object type PROCEDURE:"B"."SP_DELETESTATECONTEXTINFO" already exists
[code]...
Trying to avoid schema B in the dumpfile from being imported by specifying SCHEMASBut I got the following error
ORA-39065: unexpected master process exception in MAIN
ORA-12801: error signaled in parallel query server PZ99, instance oracth214:HEWRAC1 (1)
ORA-01460: unimplemented or unreasonable conversion requestedMaybe REMAP_SCHEMA and SCHEMAS parameters won't work together.
Is there any way to prevent the impdp from importing user B and its objects ?
I want to export a table ( using exp or expdp ) from client machine. Dump file should be created to client machine.

I have a question related to Oracle Data Pump.
So, I want to export two schemas from database with condition:
1. I want to export scheme_1 with all metadata objects + data.
2. I want to export scheme_2 with only metadata objects.
Oracle version is Oracle EE 10.2.0.4.0, OS - Microsoft Server 2003R2.
As far as I know I can not use parameter EXCLUDE like:
EXCLUDE =TABLES:" IN ('SCHEMA_NAME.TABLE')"
(-but this parameter will give me no tables at all) or I can not use CONTENT=SCHEMA_NAME.METADATA_ONLY, maybe I can use QUERY=where table in (select tablename where schema is .... - but I have tables with same name in both schemas).
