SMO vs Invoke-Sqlcmd in Azure

Grant Fritchey, 2013-05-28

I’m working on a series of Powershell scripts for the pre-conference seminars on Windows Azure SQL Database that I’m going to be giving at TechEd and the PASS Summit. One of the things I want to do is script out a full backup process (one that’s consistent with transactions) which means I need to create a database copy. There’s a nice neat T-SQL command that does this:

AS COPY OF nmhdhskcew.AdventureWorks2012;

So, being the lazy Powershell freak that I am, I figured I’d just pass it in with Invoke-sqlcmd as a single line like this:

Invoke-Sqlcmd -ServerInstance $server -Database $db -Username $user -Password $password -Query $sql

Which resulted in an unexpected error:

Invoke-Sqlcmd : The CREATE DATABASE statement must be the only statement in the batch.

Well, now I’m curious. I’m passing in a single command. It’s not part of any other commands or statements or batches. What if I did the same thing in SMO?

$cn = ';User ID=CloudAdmin;Password=@password;Trusted_Connection=False;'
$conn = New-Object System.Data.SqlClient.SqlConnection
$conn.ConnectionString = $cn
$srv = New-Object ("Microsoft.SqlServer.Management.Smo.Server") $conn
$db = $srv.Databases["master"]

It worked flawlessly. Hmmm… Maybe there’s an extra command being passed in from Invoke-Sqlcmd? Not sure. But it’s interesting.

Speaking at Community Events – More Thoughts

Last week I posted Speaking at Community Events – Time to Raise the Bar?, a first cut at talking about to what degree we should require experience for speakers at events like SQLSaturday as well as when it might be appropriate to add additional focus/limitations on the presentations that are accepted. I’ve got a few more thoughts on the topic this week, and I look forward to your comments.
