Re: How to find double entries

Hi,

In a recent linux magazine article (http://www.linux-mag.com/id/5679)
there was a mentioning of Full-Text Search Integration. Which I know
nothing about, but sounded interesting to me. You might want to
check it out.

Subject: [SQL] How to find double entries

Hi,

how can I find double entries in varchar columns where the content is
not 100% identical because of a spelling error or the person considered
it "looked nicer" that way?

I'd like to identify and then merge records of e.g. 'google', 'gogle',
'guugle'

Then I want to match abbrevations like 'A-Company Ltd.', 'a company
ltd.', 'A-Company Limited'

Is there a way to do this?
It would be OK just to list candidats up to be manually checked afterwards.

Regards
Andreas
