Andy Warren

I started my SQL journey here at SQLServerCentral as one of the founders, helping to build a place to share and learn that continues to thrive under the editorial guidance of my friend Steve Jones. I've done a lot of volunteer work over the years ranging from our local SQL group (oPASS, SQLOrlando) to serving on the Board of Directors of PASS to designing and building the framework of SQLSaturday (which has gone on to produce more than 1000 locally managed events since we started in 2007). These days I manage a DBA team, but over the years I've been a trainer, consultant, contractor, and DBA. I'm rarely present on social media, the best way to contact me is here, LinkedIn, or via email.

Using the Copy Database Wizard

In a follow up article to Rahul's article on 'Copying Databases from Server to Server' Andy looks at another option, the Copy Database Wizard introduced in SQL 2000. Easy to use, but like most wizards it has a couple gotchas you need to know about. Good article for beginners and pro's alike!

The Case for SQL Logins - Part 1

Andy says Windows Authentication "is bad". What? That's not what Microsoft says! Heck, that's not even what we say! Everyone knows NT authentication is the way to go. Then again, when was the last time Andy wrote an article that wasn't worth reading?! Read the article, rate it and add a comment - and automatically be entered in a drawing for a copy of SQL Server 2000 Performance Tuning donated by Microsoft Press.

Question of the Day

Fixing the Error

On SQL Server 2025, I have a database that has this collation: SQL_Latin1_General_CP1_CI_AS. I decide I want to run this code:

SELECT UNISTR('*3041*308A*304C*3068 and good night', '*') AS 'A Classic';
I get this error:Msg 9844, Level 16, State 4, Line 24 The char/varchar input type uses an unsupported collation. Only a UTF8 collation is supported with char/varchar input type in UNISTR function.What is the easiest way to fix this error?
