All of the columns in the query must be named so each of the columns in the table will have a name. Sometimes they were set to specific values or the of calculations using the Transact-SQL (T- SQL ) SET statement. The temporary tables are useful for storing the immediate result sets that are accessed multiple times. I tried to search if this is covered as a part of any KB article but invain.

Creating temporary tables. Both provide the same functionality, but there are two important differences between these two, which may affect your decision about which one to use. Which one is more efficient: select from linked server or insert into.
