Your application code may look neat and clean, and you are using a sound Object-relational Mapper, but when you put the pedal to the metal, you're not getting the performance.

Conditional Split is one of the most commonly used transforms in any SSIS Package development routine. The limitation with conditional split is that any record that satisfies the first condition from the conditions list is routed to its corresponding path exclusively. In a logical sense, a record might satisfy more than one condition and one might want the record to be routed to all paths for processing, but with the Conditional Split transform this is not possible. We need a more intelligent conditional split where we can selectively route the records to more than one output path. In this tip we will look at how to facilitate this intelligent conditional split.

I have a database, DNRTest, that has a number of tables and other objects in it. The other day, I was trying to mock up a test and ran this code on the same server:
-- run yesterday CREATE DATABASE DNRTest2 GO USE DNRTest2 GO CREATE TABLE NewTable (id INT) GOToday, I realize that I need a copy of DNRTest for another mockup, and I run this:
-- run today USE Master BACKUP DATABASE DNRTest TO DISK = 'dnrtest.bak' GO RESTORE DATABASE DNRTest2 FROM DISK = 'dnrtest.bak' WITH REPLACEWhat happens? See possible answers
