What is this SQL Code doing?
Can someone tell me what "umc" is referencing, or how it is being populated in this query.
I have a basic understanding of the #temp for temp tables but I am a bit puzzled with what is going on with "umc".
umc.txt

The use of temporary tables and partitions is this regular SQL or Transact-Sql? Since you are able to access temproary tables as well as the tables on the server what differentiates this code from regular MSSql code?
Yes they get used quite a lot in TSQL soryr mate not sure what you mean by regular SQL.
This is valid MSSQL(TSQL) code, copying it into Sql Server Management Studio and performing a syntax check runs fine, so it is likely valid.
