The day before SQL Saturday Silicon Valley, SQL Server MVP Steve Jones will be hosting a free seminar in San Jose on March 14 2014. Join fellow database professionals to learn best practices and practical tips for SQL Server version control, continuous integration and deployment.
A common method to detect if a row has changed is to compare hashes. Integration Services itself doesn’t have a hash implementation, so in this tip I’ll show how you can implement a hash detection mechanism using a script component, as an alternative to the pure T-SQL solution.
sp_ExecuteSQL can be used to dynamically execute T-SQL code. Learn how to use it and how to add parameters to control what code is executed.
We might not be able to stop hacks, attacks, or issues with our databases, but knowing that they've occurred is important. Steve Jones notes that we might need auditing more than security.
All DBAs need to engage in a little project management to help make sure everything runs smoothly. In this extract from the book Tribal SQL, David Tate explains his system for managing workload, colleagues, and projects, and how not to be just "the guy who says no".
March 15, SQLServerCentral's Steve Jones and many others (including Kalen Delaney, Kevin Boles, and Karen Lopez) will be presenting at SQL Saturday Silicon Valley. This is a free, one-day learning event about SQL Server, Microsoft Business Intelligence, and Big Data. Register soon while spots are available.
Has the SQLCLR system impacted your SQL Server environment? Steve Jones wants to know if it has or has not today.
A Hyper-V replica will provide a rapid disaster-recovery by simply replicating to a standby site a VM running at the primary site. Is it, therefore, ideal for running SQL Server in high-availability? Well, it depends on the type of HA you require, and whether you need the features that aren't supported.

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
