I have got a simple contacts database but I'm having problems with users entering in duplicate data. I have implemented a simple data comparison but unfortunately the duplicated data that is being entered is not exactly the same. For example, names are incorrectly spelled or one person will put in 'Bill Smith' and another will put in 'Wi...
What's the simplest SQL statement that will return the duplicate values for a given column and the count of their occurrences in an Oracle database table?

Earlier this week I ask a question about filtering out duplicate values in sequence at run time. Had some good answers but the amount of data I was going over was to slow and not feasible. Currently in our database, event values are not filtered. Resulting in duplicate data values (with varying timestamps). We need to process that data ...
I have a table that holds only two columns - a ListID and PersonID. When a person is merged with another in the system, I was to update all references from the "source" person to be references to the "destination" person. Ideally, I would like to call something simple like UPDATE MailingListSubscription SET PersonID = @DestPerson WHER...

A query that is used to loop through 17 millions records to remove duplicates has been running now for about 16 hours and I wanted to know if the query is stopped right now if it will finalize the delete statements or if it has been deleting while running this query? Indeed, if I do stop it, does it finalize the deletes or rolls back? ...
This has been an adventure. I started with the looping duplicate query located in my previous question, but each loop would go over all 17 million records...meaning it would take weeks (just running *select count * from MyTable* takes my server 4:30 minutes => mssql 2005). I gleamed information from this site and at this post: http:/...
Hello, He're an interesting problem that looks for the most Pythonic solution. Suppose I have a list of mappings {'id': id, 'url': url}. Some ids in the list are duplicate, and I want to create a new list, with all the duplicates removed. I came up with the following function: def unique_mapping(map): d = {} for res in map: ...
Some thing ago, I write small script using Text::DeDupe to remove duplicates of blog posts before I have to lay my eyes on them. After reading Syntactic Clustering of the Web paper on which implementation is based, I would love to have ability to find overlapping documents (e.g. snippets of blogs as opposed to full text, maybe also quot...

I have a bunch of documents in a MarkLogic xml database. One document has: <colors> <color>red</color> <color>red</color> </colors> Having multiple colors is not a problem. Having multiple colors that are both red is a problem. How do I find the documents that have duplicate data? ...
I have a web application (ASP.Net 3.5) with a conventional 3 layer design. If the user clicks a button a postback happens, some middle and data layer code runs, and the screen is refreshed. If the user clicks the button multiple times before the first postback is completed my logic gets confused and the app can end up in an invalid state...
Hi, I need to transfer data from one table to another. The second table got a primary key constraint (and the first one have no constraint). They have the same structure.

What is the best way of doing this without overloading the database? I have seen a sort of subquery where you use "WHERE NOT EXISTS ()" I just want to know the most efficient ...
I have a large number of text files (1000+) each containing an article from an academic journal. Unfortunately each article's file also contains a "stub" from the end of the previous article (at the beginning) and from the beginning of the next article (at the end). I need to remove these stubs in preparation for running a frequency an...
