I tried to simply create a table with the structure of another table to sync them contents later. When is use "CREATE as SELECT", it just returns the error ORA-00933 "SQL command not properly ended"
As mentioned in the link, the syntax should be OK. https://www.techonthenet.com/oracle/tables/create_table2.php Both tables should be stored in the same user scheme. The only difference is the added user scheme and tablespace.
CREATE TABLE "MYUSER.TABLE_B"
as (SELECT * FROM "MYUSER.TABLE_A")
TABLESPACE "SANDBOX" ;
