All the above mentioned answers will almost fullfill the purpose. However, You need to drop the temp table after all the operation on it. You can follow-

INSERT INTO #TempTable (ID, Date, Name) 
SELECT id, date, name 
FROM physical_table;

IF OBJECT_ID('tempdb.dbo.#TempTable') IS NOT NULL 
    DROP TABLE #TempTable;

INTO #TempTable
FROM table
