Answer 1

MySQL does not support SELECT INTO [table]. It only supports SELECT INTO [variable] and can only do this one variable at a time.

What you can do, however is use the CREATE TABLE syntax with a SELECT like so:

Answer 2

If you want to create a new table as a Duplicate table.

CREATE TABLE WorkerClone LIKE Worker;   //only structure will show no data
CREATE TABLE WorkerClone Select * from  Worker; //DUPLICATE table created with all details.

Answer 3

MySQL does not support the SELECT ... INTO ... syntax.

You have to use the INSERT INTO ... SELECT .. syntax to accomplish there.

Answer 4

INSERT ... SELECT

http://dev.mysql.com/doc/refman/5.1/en/insert-select.html

INSERT INTO newsletter_to_send
SELECT id_subscriber FROM subscribers 

PS: are you sure you don't need in WHERE clause?

Answer 5

mysql don't support SELECT ... INTO ... syntax,

if it's a new table, use CREATE TABLE ... SELECT ... syntax.

example:

CREATE TABLE artists_and_works
  SELECT artist.name, COUNT(work.artist_id) AS number_of_works
  FROM artist LEFT JOIN work ON artist.id = work.artist_id
  GROUP BY artist.id;

I tried working on this just now and this works for me:

CREATE TABLE New_Table_name
SELECT * FROM Original_Table_name;
