The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Selecting an identity column by name from a #temp table

Asked by knightEknight in MS SQL Server

Tags: alter column identity

SQL Server 2000

When I add an identity column to a #temp table, I can't select the column by name.  However, if I select * from the table, I can see the column and it contains the expected values.  I need to be able to select just the column by name.  I've simplified the problem into the code below (see comments).

Thanks

select 99 as myInt, 'xyz' as myChar
into #temp1
 
alter table #temp1 add row_id int identity
 
select * from #temp1    -- works (including the row_id column)
select myInt, myChar  from #temp1  -- works as expected
select myInt, myChar, row_id from #temp1  -- does NOT work - invalid column name: row_id  ????
 
drop table #temp1
