Updating a row in sql server 2016 Live chat roomsex

It is an interesting problem in Transact SQL, for which there are a number of solutions and considerable debate.How do you go about producing a summary result in which a distinguishing column from each row in each particular category is listed in a 'aggregate' column?

I tried to duplicate the issue, but on the systems I tested with I was not able to recreate the issue.Let's say we want to increment by 10 instead of by 1.We can do the update as we did above, but use a value of 10 to have the ids in increments of 10 for each record.For example, assume that you create a table named DECLARE @t TABLE (my Key int); UPDATE My Test SET my Value = 2 OUTPUT Key INTO @t(my Key) WHERE my Key = 1 AND RV = my Value; IF (SELECT COUNT(*) FROM @t) = 0 BEGIN RAISERROR ('error changing row with my Key = %d' ,16 -- Severity.,1 -- State ,1) -- my Key that was changed END; CREATE TABLE My Test2 (my Key int PRIMARY KEY ,my Value int, TS timestamp); GO INSERT INTO My Test2 (my Key, my Value) VALUES (1, 0); GO INSERT INTO My Test2 (my Key, my Value) VALUES (2, 0); GO DECLARE @t TABLE (my Key int); UPDATE My Test2 SET my Value = 2 OUTPUT Key INTO @t(my Key) WHERE my Key = 1 AND TS = my Value; IF (SELECT COUNT(*) FROM @t) = 0 BEGIN RAISERROR ('error changing row with my Key = %d' ,16 -- Severity.column of a row to easily determine whether any value in the row has changed since the last time it was read.
