Is there a keyword or metainformation in SQL Server that’ll tell you if TOP took effect?
EX:
Select TOP 5 * From Stuff
RESULT: 5 rows
What is the best way to determine if there would have been 6 or more?
I could do:
SELECT TOP 6 count(*) FROM Stuff
But I am concerned about a separate call to retrieve the count because there actual query is much more complicated than this one and on a large table.
Thanks!
Well, you could select the top N+1 (where N in your example is 5, so in your example select the top 6) and discard the last one in your client code, and use the presence of a sixth element to determine if TOP would have had an effect had you used N in the first place. I am not sure there is much value of doing this, however.
