hello
I do not speak English, but I will try to understand you

I am new in this forum
I have a question
I use oracle9i with dev6i

I have three Computers working in the same program separately
and I have a main computer works the same program separately

How do I export database for new inputs only from three Computers
Or how do I import new inputs only to main computer
To update my main computer from others

thank you

Check the QUERY parameter; it allows you to specify a WHERE clause which might help you extract only the most recent data, such as
where date_column >= trunc(sysdate)
There are certain restrictions which apply to this parameter so - read the documentation, see if it helps.

pretty picture
Words have meanings!
only the EXPORT utility knows how to produce "DMP file".
EXPORT utility requires to connect to online Oracle database.
Does Oracle database now reside on PC1, PC2, & PC3?

You are on the wrong track using exp/imp or Data Pump for this task.
Just spool in a csv file new data in each PC and load these files in Excel on the main PC to print them as you want.

Your only question now is: "how to determinate new data in each PC?" and this only depends on your data model which will also determine the csv files you will generate.

If you don't or can't answer this question, it is useless to investigate more.
If you want more help from us, you have to post your data model (all tables with their constraints). TOAD can help you to do this.

results depend directly upon the actual content of C:\DATA.DMP

IMP can only retrieve what data that resides in DATA.DMP file;
which may be anything from FULL database (every schema & every table) to only metadata from single object.
We can not know what IMP USERNAME/PASSWORD FILE=C:\DATA.DMP LOG=C:\DATA.LOG FULL=Y IGNORE=Y produces without know exactly how DATA.DMP was created.
