You have to switch off the partitions you don't want any more with ALTER TABLE {table_name} SWITCH PARTITION {partition number} TO {destination table}. Thereafter you can drop the table if...

I don't know the number of rows it will return, but your non-ansi query translates to this:

Thanks Gianluca.. what if i dont have a order by clause? still the top operator is processed only after getting the result set?

Take a look at that article, it's an eye-opener. I'm sure you'll find it enlightening.

BEGIN

RETURN (

SELECT TOP 1 SUBSTRING(@Parameter,N+2,CHARINDEX(',',@Parameter,N+1)-N-2)

FROM dbo.Tally

WHERE N < LEN(@Parameter)

AND SUBSTRING(@Parameter,N,1) = ','

ORDER BY N

)

END

CREATE TABLE Test (

valueList varchar(8000),

firstValue as dbo.FirstToken(valueList)

)

INSERT INTO...

Creating indexes will slow down writes, but will improve read performance.

What exactly is unclear to you of the above?

I could say at a first glance that you are using a #temp table that could be avoided using a CTE, but there's much more that could be involved in...
