Ответы Re: COPY from file to table containing unique index  (Joel Burton <jburton@scw.org>)
Список pgsql-general
I have a table with over 1,000,000 records in it containing names and phone
numbers, and one of the indexes on the table is a unique index on the phone
number.  I am trying to copy about 100,000 more records to the table from a
text file, but I get an error on copying because of duplicate phone numbers
in the text file, which kills the COPY command without copying anything to
the table.  Is there some way that I can get Postgres to copy the records
from the file and just skip records that contain duplicates to the unique
index? I found that using PHP scripts to do inserts for a file of this size
take MUCH longer than I'd like, so I'd like to avoid having to do it that
way if I can.  Any help is appreciated.  Thanks!
