You can also do the following:

CREATE TABLE #TEMPTABLE
(
    Column1 type1,
    Column2 type2,
    Column3 type3
)

INSERT INTO #TEMPTABLE
SELECT ...

SELECT *
FROM #TEMPTABLE ...

DROP TABLE #TEMPTABLE

select *
into #TempTable
from SomeTale

select *
from #TempTable

In Sqlite:

CREATE TABLE T AS
SELECT * FROM ...;
-- Use temporary table `T`
DROP TABLE T;
