CREATE TABLE as SELECT - using MEMORY ENGINE (in RAM memory)

Question

I was reading about tables using MEMORY ENGINE (tables stored in ram).

• Is it possible to use CREATE TABLE AS SELECT syntax, but have the create

Answer 1

you can also create a temporary table this way:

CREATE TEMPORARY TABLE IF NOT EXISTS tmp ENGINE=MEMORY AS (
SELECT 'abc' As tomcat, 'def' As apache);

Or this way:

CREATE TEMPORARY TABLE IF NOT EXISTS tmp ENGINE=MEMORY AS (
SELECT tomcat, apache From servers);

Be advised, the first option will create the two columns as varchar(3), meanwhile the second option will import any column information from the original table, even their comments.
