I've no idea how I entered multiple, identical rows in a table but I want to
delete all but one of these rows.
Here's an example:
bustrac=# select * from projects where proj_nbr = '4242.01';
proj_nbr | proj_name | start_date | end_date | description | notes
----------+----------------+------------+------------+---------------+-------
4242.01 | Expert witness | 2008-10-15 | 2008-10-28 | Consol Energy |
4242.01 | Expert witness | 2008-10-15 | 2008-10-28 | Consol Energy |
4242.01 | Expert witness | 2008-10-15 | 2008-10-28 | Consol Energy |
4242.01 | Expert witness | 2008-10-15 | 2008-10-28 | Consol Energy |
(4 rows)
How do I clean this up so there's only a single row for this project number?
TIA,
Rich
