Data Pump query

Question

Just started looking at data pump yesterday and it seems like a great tool.
I've been no issues in getting data transferred between databases and mapping to original tables. However I have refactored a couple of parts of my db and hoped I could get a pointer in the right direction.
http://docs.oracle.com/cd/B12037_01/server.101/b10825/dp_import.htm
I'm hoping to import some of my data from table BAD_DESIGN from my old schema and move a section of it to table GOOD_DESIGN in my new schema - I'm also hoping this is possible on the import.
eg.
OLD.BAD_DESIGN table
name1 VARCHAR 2
number1 INTEGER
name2 VARCHAR 2
number2 INTEGER
name3 VARCHAR 2
number3 INTEGER
I want to take only name1 and number 1 and insert into my new tables
NEW.GOOD_DESIGN table
name1 VARCHAR 2
number1 INTEGER
The instruction I've pasted below is not working which is obvious as I'm not defining the column the data should be inserted into in the new schema. I also don't think I need a function to remap the data here ...
impdp NEW/NEW_PASSWORD@NEW_DB:PORT/SERVICE dumpfile=BAD_DESIGN.dmp TABLES=NEW.GOOD_DESIGN CONTENT=DATA_ONLY remap_data=OLD.BAD_DESIGN.name1:remapConfig.remapString \
Is this even possible with a data pump? If so, a pointer to what I'm missing in the instruction or the documentation would be appreciated.

Answer 1

Thanks for the reply
Database versions are 10.2.0.4.0 (old) and 11.2.0.3.0 both sitting on a Linux server.
Are you asking if datapump can be used to move data from a table that contains 6 columns into a table that contains 2 columns ?
Kind of....not realy specifically to do with the amount of columns, more to do with can I get a subset of data from a data dump and import it into a different table in a refactored db.
To clarify I'm asking if data containted in two columns in an old table can be 'extracted' from the .dmp file and inserted into a different table in a different schema (column types remain the same).
To clarify with a better example - I have a table
OLD.FAMILY
dad_name VARCHAR2
dad_age INTEGER
mum_name VARCHAR2
mum_age INTEGER
child1_name VARCHAR2
......etc.
I export this table using datapump
Now I want only want to insert the data from dad_name and dad_age into my new table
NEW.DAD
name VARCHAR2
age INTEGER
