TSQL Challenge - Table Truncation - 29 Jul 2011 Commented on: 6 years ago (July 30, 2011) How important is it that the view V1 reports the correct values throughout the (fast clearing) operation?
TSQL Challenge: Packing Date and Time Intervals Commented on: 6 years ago (January 29, 2011) Is anything to be gained from taking advantage of the 60-minute maximum for a session in the test data, Itzik?
T-SQL Challenge with SQL Server 2012’s Sequence Object Commented on: 6 years ago (December 16, 2010) Most efficient way I can think of is to have the sequence INCREMENT BY 2 each time, and insert (NEXT VALUE FOR dbo.Seq1) and (NEXT VALUE FOR dbo.Seq1 + 1) into key1 and key2 (respectively) in T1....
SQL Server 2012 T-SQL at a Glance – Sequences Commented on: 6 years ago (November 23, 2010) I believe I'm right in saying that other than column order, the order of items in the SELECT list doesn't mean anything - so it would be wrong for SQL Server to arbitrarily provide e.g. 1 as the...

Solutions to T-SQL Challenge - Efficient Partitioned TOP Commented on: 7 years ago (October 31, 2009) You can cheat by relying on the randomness of the data inserted into the table an put "WHERE col1 > 95" at the end of the inner query - limiting the size of the sort. Not recommended for production...
Virtual Auxiliary Table of Numbers Commented on: 7 years ago (October 30, 2009) I've tried the recursive approach you suggest, oddsock and as per article #94376, having the OPTION within the function doesn't work (syntax error) - it'd be a huge pain to have to remember to...
T-SQL Challenge - Duplicating Form Entries Commented on: 8 years ago (August 25, 2009) ccasimor - yes it is possible to insert into two tables in a single statement in SQL Server 2008.
Optimizing a Suboptimal Query Plan Commented on: 8 years ago (March 26, 2009) Hi Itzik, Further to my earlier reply - here are some timings (T1 w/ 1,000,000 rows, col2 'pseudorandomizedish' - SQL Server w/ 768MB RAM, testdb and tempdb on separate disks). Original query: 29s...
