This is exactly the situation where I use PowerShell frequently. I am able to export data from whatever complex query. Idea is something like this:
Invoke-Sqlcmd -ServerInstance myServer -Database MyDb -Query "SELECT * FROM SomeTable" | Export-Csv ./result.csv -NoTypeInformation
In -Query can be any T-SQL code and results are exported natively to CSV file. I work as ConfigMgr admin and this is the way how you can really easily receive your data.

I know this post is more than 2 years old but curiosity finally got the best of me. "Everyone" keeps recommending that PowerShell be used for these types of things but not once have I seen them identify how you could use PowerShell in a stored procedure. 😉 Also, why even bother with PowerShell when this is so easily done without it and it works in a stored procedure or a function without having to somehow get to the command line to do it?

Yes, if you're trying to create a CSV file, the PowerShell solution works just fine but why would you use it instead of T-SQL if the target was also T-SQL or just a result set to an app?

How would you do it in T-SQL?

If you're just outputing a result set (which is the object of the article... not exporting data), then just like the article does with the [text] kicker. I'm not sure why anyone would even bring up PowerShell in such a situation.

I think Wayne already called out that the comment was misplaced.

I thought you were taking things in a different direction.

Yeah, but I need to call it out.

On the other thing, I don't want to ruin Wayne's fine discussion with discussions on visceral fear. 🙂

Why? What's your point?

No Jeff, that's not how it works. You do not get to make petty jabs and then try taking the high ground while using Wayne's (fine) article as a shield.

Regarding "visceral fear", can you really blame me? Have you seen this thread?

S******y issues aside, do you think if more people knew that every so often when you call xp_cmdshell that it might force you to restart the entire SQL Server service that more people might sart avoiding it? :Whistling:

Sure I do and sure I will. Not here, Orlando. Let's go to another thread if you want to continue.

I know that this is a repost of an older article from 2011 and that there have been some new functionality introduced in recent version. I have used the FOR XML and STUFF() method many times and it is great, it has really saved my bacon on a few occasions. This was why I was glad to find the introduction of the STRING_AGG() function is SQL Server 2017. With this function you can replace the entire second part of the script from "WITH CTE" down with the following.

SELECT AccountNumber,

STRING_AGG(Value,',') AS CommaList

FROM #TestData

GROUP BY AccountNumber

ORDER BY AccountNumber;

I hope that those of you lucky enough to have an up to date system will find this easier.
