CREATE TABLE LIKE A1 as A2

Question

I want to create a new table with properties of an old table and without duplicates. I want to do something like this:

CREATE TABLE New_Users  LIKE Old_Users,  AS (SELECT * FROM Old_Users GROUP BY ID) ; 

But the above is not working. Can anybody modify it to work?

Answer 1

Your attempt wasn't that bad. You have to do it with LIKE, yes.

In the manual it says:

Use LIKE to create an empty table based on the definition of another table, including any column attributes and indexes defined in the original table.

So you do:

CREATE TABLE New_Users  LIKE Old_Users; 

Then you insert with

INSERT INTO New_Users SELECT * FROM Old_Users GROUP BY ID; 

But you can not do it in one statement.
