Hi,

I’m looking for a similar but different query that I’ve been twisting my brain trying to figure out. Your post is the closest I’ve come to finding an answer.

I’m querying a table where multiple people might be selling the same item (ItemID). What I want to do is get all unique items, and for each unique item, get a count of how many duplicates there are for that unique item. I want a list of all unique items, not just the ones that have duplicates. (For ones with no duplicates, the duplicate count can can be one or zero, I don’t care.)

A simplified version of the ForSale table is:
[ID] [uniqueidentifier] NOT NULL CONSTRAINT [DF_Selling_ID] DEFAULT (newsequentialid()), — This is the primary key
[ItemID] [uniqueidentifier] NOT NULL,
[Description] [nvarchar](max) NULL

There is a second table “Items” that contains the information about the item in question. I’m trying to link the output of the

I’ve gotten almost all the way with your above query:

SELECT ItemID, Count(1) TotalCount
FROM ForSale
Group BY ItemID
HAVING COUNT(1) > 0
ORDER BY COUNT(1) DESC

But I can’t figure out how to get the Item info also brought into the results of the query. I thought an inner join would do the trick, but then I end up with a record for each ForSale, defeating the unique.

Any ideas?

Duplicate on what basis? Are the columns fixed?

By: Javed Ahmad Qureshi

Javed Ahmad Qureshi — Thu, 13 Oct 2011 04:01:21 +0000

I am into an upgrade process of my software application, and it gives me error of duplicate records found in tables. My database contains more than 1000 tables and I’m unable to execute the query on each table manually. Is there any possibility that a single query can check all tables in the whole database for duplication?

Why do you want to use while loop? What is wrong with the example given in this post? Using While loop is ineffecient

Javed Ahmad Qureshi — Wed, 12 Oct 2011 11:29:59 +0000

I have a question, could anybody guide me to have a WHILE … LOOP query to run the duplication check on first two columns of all tables in a specified database?

Thank you. I’d forgotten how to do this and your post pushed me back in the right direction.
