Nothing, anywhere, is perfectly secure. There are always vulnerabilities. We just don't always know what they are until it's far too late.

However, I still land where I always land on...

In addition to changing the capture mode to auto, look to custom to get a little more control, possibly.

When connections do not happen in SQL Server, there's nothing in the error logs because there really isn't anything for SQL Server to report. However, that's not saying that there...

Because of the row size limitation in SQL Server, I had to split the columns of a data warehouse table. The combined size of the rows exceeded the permitted...

What performance problem are you trying to solve by splitting the table? Reads are likely to go up, not down (depending on quite a few details). Writes may go down,...

Nothing jumps out as problematic, so it is going to be down to knowing the structures and execution plan. Without that, we can't even guess.

Strong suggestion.

Restore the database as everyone has suggested. Then, before you change the compatibility level, turn on Query Store. Run the database for some time with Query Store enabled. A...

What goes around comes around.  The person you help today may remember you when they get their next position.  There is a pleasure to be had when you hear...

In general, T-SQL just doesn't lend itself to code reuse. I've seen lots of attempts at using functions as a way to turn T-SQL into more of a development language....

I'd use CHARINDEX. You can search for an expression, as simple as looking for the space, within the string and return the value where that space is.

If you're just talking VMs on Azure, yeah. Same behaviors as VMs anywhere else. If you're talking Managed Instance or Azure SQL Database, different rules. Very.

Aggregation versus sorting. A lot less work to sort than aggregate. Also, a join operation versus none.

Also, you can get much more accurate measures if you use Extended Events.

Yeah, I'm a little surprised they don't have either Query Store or Extended Events working on it. Seems like a necessity. The DMVs are nice, but cache dependent, so it's...

3rd party solution (my employer), Redgate Software makes a tool, SQL Compare, that can actually look directly at the backup file and compare that to a database to find differences....

Source control your database code. All of it.
