Transact-SQL Programming Review

By rohan Pitiya

from Undisclosed

Comments about oreilly Transact-SQL Programming:

REgarding the article publish in sqlservercentrl on t-sql performance tunining Part -2 which is an extract from this book....

1.It says on p12, by adding anotther constraint( p.productid = s.productid) in the where clause you get a perfomace boost. If SQL server doesn't know A=c when A=B and B=C, then sql has to check this which means an added overhead(redundant) to the the query. In my experiecnce I have removed lot of this type redunant filterations which boosted performance(opposite to the argument)

2. When using OR replacing with UNION queries..

this again if you have or statements in one query, when sql evaluates from left to right, the first neagative condition will end the checking. But as you indicate, irrespective of results, sql has to evaluvate for all coditions in the OR clause.

Transact-SQL Programming Review

By Matt

Comments about oreilly Transact-SQL Programming:

This book is now extrememly out of date. The datatypes are not even up to date with SQL Server 2000. You need a new version of this book that is up to date. $50 is also way to much for a book that is now two versions behind (because this doesn't even cover version 7.0 completely). I have come to expect better from O'Reilly...

Transact-SQL Programming Review

By Mike T.

from Undisclosed

Comments about oreilly Transact-SQL Programming:

Down-to-earth and practical manual. It is comparable with

'PL/SQL Oracle programming' book that Oreilly sells in

its scope, accuracy, and depth of coverage.

I recommend this book for anyone with experience in procedural

SQL-based languages new to Transact-SQL environment. The

presentation is layed out logically and in well-paced units.

Some humor is sprinkled at the right frequency to keep material

from becoming desert-dry.
