Revised Script: Indexing and looking for a cursor in an update statement

I ran a QC script over the results of yesterday's cursor counts table, and realized I had made a logical error.

Here's the QC scripts:

select count(*) as counted, 'photos' as [Source] from dbo.photos union all select count(*) as counted, 'photos-null votes' as [Source] from dbo.photos where tally is null union all select count(*) as counted, 'votes' as [Source] from dbo.votes; select top 10 * from dbo.photos; select top 10 * from dbo.votes; select sum(tally) as TotalVotesCounted from dbo.photos; select top 10 * from dbo.votes as v left join dbo.photos as p on p.id = v.photoID where p.tally is null

And here's the revised creation script:

set nocount on; use enron; go if object_id('dbo.photos') is null create table photos (id INT identity(1,1) primary key, photo varbinary(max), tally INT); else truncate table dbo.photos; go if object_id('dbo.votes') is null create table votes(id INT identity(1,1) primary key, userID INT, photoID INT); else truncate table dbo.votes; go DECLARE @counter INT; SET @counter = 1; WHILE @counter < 500 BEGIN insert into dbo.photos(photo) values(rand() * 1000) SET @counter = @counter + 1 END; GO DECLARE @counter INT, @userid int, @photoid int, @msg varchar(256); SET @counter = 1; WHILE @counter < 50000 BEGIN SELECT @userid = rand() * 100; select @photoid = rand() * 1000; if (@photoid between 1 and 499) insert into votes(userid, photoid) values (@userid, @photoid) SET @counter = @counter + 1; END; GO
