Re: Help with IMPort

The best method that I know is:

1. export from production.
2. drop user cascade in development or at least drop all tables.
3. create user in development.
4. import into development with indexes=n and constraint=n.
5. import again into development with rows = n and ignore = y.

Step 4 will build all the tables with the data. Step 5 will build indexes and enable constraints.

If the tables already exist in the target database then import will not recreate them.
As for the data you may have constraints that reject the insert of records.

Lets say you have a fact table and a lookup table that contain the branches names.
On the fact table you have constraint: branch id must be in the branch table.
When you import the fact table before the branch table all the records will be rejected because the branch table does not have the ids yet.
