how can I create a copy of an Oracle table without copying the data?

• https://stackoverflow.com/questions/233870/how-can-i-create-a-copy-of-an-oracle-table-without-copying-the-data#233890

create table xyz_new as select * from xyz where rownum < 0;

In Oracle SQL Developer

• use the menu-function (maybe right-click) on the table you want to operate on (i.e. that you want to copy),
• “Table“,
• “Copy…“,
• w/o checking “Include Data“.
