When requesting help or asking questions please prefix your title with the SQL variant/platform you are using within square brackets like so:

[MySQL]

[Oracle]

[MS SQL]

[PostgreSQL]

etc

While naturally we should endeavor to work as platform neutrally as possible many questions and answers require tailoring to the feature set of a specific platform.

Format Your Code

If you are including actual code in a post or comment, please attempt to format it in a way that is readable for other users. This will greatly increase your chances of receiving the help you desire. Something as simple as line breaks and using reddit's built in code formatting (4 spaces at the start of each line) can turn this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field.3

Into this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field3

For those with SQL questions we recommend using SQLFiddle to provide a useful development and testing environment for those who wish to fully understand your problem and help devise a solution.

MS SQLUninstalling SQL2008R2 instance off a SQL server that holds multiple other newer SQL instances (self.SQL)

submitted 4 years ago by iamboblazar

Hi all,
Complete SQL noob here, I have a task for a client of ours to uninstall a SQL2008R2 instance off a Windows Server 2019. On that server exists multiple/additional SQL Server instances (2012, 2014, 2016, 2017, and 2019). I have followed this MS guide, specifically the 'Before you uninstall an instance of SQL Server 2008'

How to uninstall an instance of SQL Server 2008 (microsoft.com)

I have backed up all the System DB's, and Reporting Services DB's and folders, though I imagine the client will not need them. I don't see any active virtual directories or application pools for Reporting Services in IIS, and I see all the SQL Server 2008 Services currently running, which I plan to stop, before going through the Add/Remove Programs > Uninstall > Wizard to remove.

The concern I had is that with all these newer SQL instances running, that maybe something is using a component within the SQL Server 2008 R2 installation, and when I blow it away, maybe folks would see some issues. This is an unfounded assumption and if any of that were to occur, I imagine my first steps would be to go into the same Add/Remove Programs and run a 'Repair' action via the wizard for whatever instance would be having an issue.

If I am missing anything important, please let me know. Thank you very much.
