I have listed duplicates using the following: select s.MessageId, t.* from Message s join ( select ToUserId, FromUserId, count(*) as qty from Message group by ToUserId, FromUserId having count(*) > 1 ) t on s.ToUserId = t.ToUserId and s.FromUserId = t.FromUserId Now, how do I delete all but one of the Messages (I'm trying to remove duplicates so I can apply a unique index on FromUserId and ToUserId ). Vamsi Prabhala Use a cte and assign row numbers so that all but one for duplicate pairs can be deleted. with rownums as (select m.*, row_number() over(partition by ToUserId, FromUserId order by

Edit: When I say "SQL Server", I'm really talking about the Management Studio. Sorry if that was confusing. Oh I hate when things like this happen. I was working with SQL Server yesterday and trying out the PIVOT command to try to figure out how it worked. So I created a new table with four columns, and the first column was going to have the same value for the first few rows. I added the "value1" to the first row, first column, and hit enter - sine no keys or constraints were added yet, it allowed me to enter down to the next row with NULLs for the other columns on the first row (which is fine

When I say effective permissions, I'm referring to the permissions listed when you go into the properties of a database in SQL Server Management Studio, click "Permissions", and then click the "Effective" tab. So far, I have been able to determine the explicit permissions with the following code: using Microsoft.SqlServer.Management.Smo; ... DatabasePermissionInfo[] permissions = database.EnumDatabasePermissions("username"); However, I still need to obtain the effective permissions. In this scenario, I added a login for a user and gave it the role of db_datareader and db_datawriter for a

I'm trying to create a database on my local machine using SSMS version 11.0.2100.60. I've run the application as administrator, logged in using Windows authentication, and I've added MYDOMAIN\my-username to the Logins. However if I try to create a db with this login I get the message CREATE DATABASE permission denied in database 'master'. (Microsoft SQL Server, Error: 262) If I try to add the privelage dbcreator to my user, I get the following error. User does not have permission to perform this action. (Microsoft SQL Server, Error: 15247) I can't log in as sa as I don't know/remember the

I have a few databases that I always use SQL Server Management Studio with. I'd like to be able to create a toolbar button or keyboard shortcut that automatically opens a new query window (in the current SSMS instance) and connects to a given (registered, perhaps) database. That's it. That's all I need. And this ashtray, and the paddle game, and the remote control. That's all I need. As it is now, I have to expand the Object Explorer, collapse/expand two to eight trees, right-click on my database, and choose "New Query". I see no way to do it, this would probably save me 30-60 seconds a day.
