I know the statement:

create table xyz_new as select * from xyz;

Which copies the structure and the data, but what if I just want the structure?

Just use a where clause that won't select any rows:

create table xyz_new as select * from xyz where 1=0;

Limitations

The following things will not be copied to the new table:

  • sequences
  • triggers
  • indexes
  • some constraints may not be copied
  • materialized view logs

This also does not handle partitions
