Create Table From Query Results

Hi everybody need help on the possibility creating a new table from the results of a view or query? below is my table named table1


ID col1 col2

1 a a
2 b d
3 c f

this would be my new table named table2

ID col1 col2 col3

1 a a aa
2 b d bd
3 c f cf

this new table has an additional column by concatenating col1+col2
tried this procedure but is not working

CREATE TABLE AS (SELECT ID, COL1, COL2, COL1+COL2) TABLE2

thanks
