Is there a Primary Key or Unique index on this table?
Adrian,
No. It didn't occur to me to make the project number a PK as this table is
not related to others in the database.
But, yesterday it occurred to me to make the proj_nbr a PK to eliminate
future issues.
You might want to do something like:
select proj_nbr, count(*) as ct from projects group by proj_nbr;
to see how big a problem it is. If it is only a few projects it could
just a matter of manually deleting the extras.
Whatever you do:
1) Make sure you have a backup of at least that table.
2) Do the data changes as BEGIN; <changes> COMMIT; or ROLLBACK;
Thanks,
Rich
