Обсуждение: Importing dbf files to postgresql

Could someone recommend any utilities for browsing and editing dbf files for
importing to postgresql that will run in linux?  I have data to import, but
it contains some illegal values that need to be cleaned up.

Thanks
John Dougherty

You'll probably just write a scriptlet to filter the data for pgsql's
consumption.

I am looking for the correct way to retrieve the last 25 records from a dataset without having to first retrieve the
entiredataset to pull out the last 25. 

The potential dataset can be very large... 10,000 records that match the query... yet I only can use the most recent
25.

my first idea is:

SELECT *
FROM table
WHERE thisField=thatValue etc...
ORDER BY table_id DESC
LIMIT 25

But I'm not confident in this and looking for a yeah or nay from a guru or two or three.

Thanks,
Brian

I'm not a guru, but I have used a similar query successfully.

The same we do it for our client who used to upload DBF files and we convert
the same into PostgreSQL table.

If you wish i can send you the Binary file which will convert the DBF into
SQL table (executable on Linux)

Thanx
