This could start a flame war! I've seen instances of otherwise-seasoned coders on here using the dreaded
;WITH CTE AS (pattern, as if it's the right thing to do.
Heh... leading or trailing semi-colons... I solved that problem a really long time ago (it's why they pay me the big bucks 😀 )...
I don't end code with a semi-colon nor do I start it with one... Instead, and with some exceptions (too long to explain here but there's actually a method to my madness), I put semi-colons on their own line at the beginning of a line instead of using a blank line between queries.
That does 2 things... it's real easy to see that I remembered to add them and it satisfies both the leading and training semi-colon likes, dislikes, and eventual flame wars. 😀

Not dropping temp tables at the end of stored procedures is one of the pre-requisites to take advantage of the tempdb improvements made to limit metadata contention in tempdb, https://learn.microsoft.com/en-us/archive/blogs/sql_server_team/tempdb-files-and-trace-flags-and-updates-oh-my#metadata-contention. I've seen this contention at a couple of clients in the last year and have had to recommend code changes so that they could get those benefits.

What I find extremely frustrating is when someone writes SQL code that joins multiple tables without prefixing the column names with their originating table or alias using dot notation. This adds a significant amount of time to the task of determining which columns belong to which tables.
Gail's No, this is not a bug in T-SQL is such a great example of why it's such a bad habit. I've seen multiple instances of people saying the data engine is bugged, and it's the exact problem she outlines.

Sure, I was just trying to supply a reason why NOT dropping temp tables in stored procedures can be a performance boost. I've never practiced explicitly dropping temp tables in stored procedures because they are dropped at the end of execution anyway and are execution specific, so I never found a reason to drop.

Old programming habits die hard. Just something that carried over when I started working with MS SQL Server way back in the 6.5 days.
