select from @local_var fails to parse

[joshua-auchincloss]

Noting the engine fails to parse valid local variables, despite being previously declared. E.g query below to highlight this (engine = mssql)

declare @a int
set @a = 2
select @a * 4

Raises end of statement error (found @a at Line 3, column xxx)

What's more interesting is that after I swapped the order of the SQL statements, the result was successfully output.
