Nice straight forward question Sergiy. And something that many people don't know.

Good QotD. Someone not knowing this could introduce a serious bug into their work.

There are all kinds of interesting tidbits about table variables and temp tables. Wayne Sheffield has a great presentation on them that I really enjoyed. I'd recommend attending if anyone gets an opportunity.

Very good, Sergiy - thanks you!

Thanks everyone for positive feedbacks.

For myself I use a simple rule of thumb here:

table is a table, even if it's a temporary one, and within transactions it acts as a table;

variable is a variable, even if it's a table type one, and within transactions it acts as all variables.

Nice question. And I like that simple rule of thumb.

Managed to get it wrong by clicking as I pushed the mouse up the screen and timed the click wrong. I must be getting old and decrepit or something, obviously that sort of slip could lose a life in games that I used to play when I was much younger.

Hy Sergiy,

Please test this code on SQL Server 2016 Express.
