That looks promising.
If you want to remove the cursor, use this
-- get analyst ID
SELECT @Cntr = MIN(AnalystID)
FROM #Analyst
LEFT JOIN #MerchList
ON #Analyst.AnalystID = #MerchList.AnalystID
WHERE #MerchList.#MerchListID IS NULL
WHILE @Cntr IS NOT NULL
-- perform update
-- get next analyst ID
SELECT @Cntr = MIN(AnalystID)
FROM #Analyst
LEFT JOIN #MerchList
ON #Analyst.AnalystID = #MerchList.AnalystID
WHERE #MerchList.#MerchListID IS NULL
AND #Analyst.AnalystID > @Cntr
END
I say roll on SQL Server 2005 where you can use a varible as part of the TOP
clause.

Try this (obviously you'll need to tweak it a bit to fit your needs, but it
does the basic job):
CREATE TABLE #MerchList (
MerchListID int IDENTITY (1, 1) NOT NULL , FileDate datetime NOT NULL ,
MerchID int NOT NULL , AnalystID int NOT NULL ,
)
CREATE TABLE #tblAnalyst (
AnalystID int IDENTITY (1, 1) NOT NULL , AnalystName varchar(100) NOT NULL
)
declare @counter int
set @counter = 0
while @counter < 10005
begin
if (@counter < 26) and (@counter != 0 )
begin
insert into #tblAnalyst(analystname) values
('Analyst' + cast(@counter as varchar))
end
insert into #MerchList(filedate,merchID,analystID) values
(getdate(),@counter,0)
set @counter = @counter + 1
end
select * from #MerchList
select * from #tblAnalyst
declare @numAnalysts int, @numMerchants int, @numMerchantsPerAnalyst int,
@cmd varchar(2000), @aid int, @MerchListID int
select @numAnalysts = count(*) from #tblAnalyst select @numMerchants =
count(*) from #MerchList set @numMerchantsPerAnalyst =
@numMerchants/@numAnalysts print @numAnalysts print @numMerchants print
@numMerchantsPerAnalyst
declare curs_analyst cursor for
select analystID from #tblAnalyst
open curs_analyst
fetch next from curs_analyst into @aid
while @@fetch_status = 0
begin
select @cmd = 'update #MerchList set analystID = ' + cast(@aid as
varchar) + ' where MerchListID in (select top ' +
cast(@numMerchantsPerAnalyst as varchar) + ' MerchListID from #MerchList
where analystID = 0) '
exec( @cmd )
fetch next from curs_analyst into @aid
end
close curs_analyst
deallocate curs_analyst
declare @remainder int
select @remainder = count(*) from #MerchList where analystID = 0 print
@remainder
-- if any remainder, assign them to random analysts if @remainder > 0 begin
declare curs_merch cursor for
select MerchListID from #MerchList where analystID = 0
open curs_merch
fetch next from curs_merch into @MerchListID
while @@fetch_status = 0
begin
set @cmd = 'update #merchlist set analystID =
(select cast(rand()* ' + cast(@numAnalysts as varchar) + ' as int)) where
MerchListID = ' + cast(@MerchListID as varchar)
print @cmd
exec ( @cmd )
fetch next from curs_merch into @MerchListID
end
close curs_merch
deallocate curs_merch
end
select analystID, count(*) from #merchlist group by analystID

Subject: Assign Records to analysts
Here is my issue. I have a list of merchants
(generated daily) and I need to assign them eually
to
a set of analysts. Both the merchant list and
analyst
list can change daily.
I want to assign each merchant with an analyst daily
and need help to write out a stored procedure for
this
(do not want to use VB).
Here is relevant code for the tables:
CREATE TABLE MerchList (
MerchListID int IDENTITY (1, 1) NOT NULL ,
FileDate datetime NOT NULL ,
MerchID int NOT NULL ,
AnalystID int NOT NULL ,
)
CREATE TABLE tblAnalyst (
AnalystID int IDENTITY (1, 1) NOT NULL ,
AnalystName varchar(100) NOT NULL
)
there will be about 10000 records in table MerchList
and around 25 records in table tblAnalyst.
This will be used to assign work to analysts on a
daily basis.
Thanks for all your help!
Vishal
