Re: Duplicate rows

Depends on how you determine if something's a duplicate or not. For example, if it's just one column that can be used, you can do something like this: select ItemName, count(ItemName) from ItemListTable group by ItemName having count(ItemName) > 1 That'll show you if "ItemName" is repeated. Then you can go back through and just search for "ItemName" and remove the ones you don't want. You can do pretty much the same thing as above but CONCATenating multple columns if that's what you need to do to determine uniqueness. I know you're dealing with 15k rows still, so you probably want something a little more automated. Without more info though, it's hard to say exactly what can be done. Hope that helps a little bit. -TG = = = Original message = = = My dear beloved friends, I have a catalog of products that a product provider gave, sadly for me, in this CSV file there are many duplicated rows. I edited the file in my Linux system with the "uniq -u" command, and it worked somewhat fine, it eliminated some duplicated rows, originally the file had 24K rows, and now it has been reduced to 15k rows. Anyhow, there are still duplicated rows, and since this is a catalog, it should not have duplicated rows!!! Now the catalog has been has been loaded into the DB. How can I continue eliminating duplicated rows? As far as I remember the is a sentence in SQL to only show ONE row of duplicated rows, maybe if I do a select using this sentence and then put this new recordset in another table, it will work!!
