How To Drop an Existing Table?
Answer:
If you want to delete an existing table and its data rows, you can use the DROP TABLE statement as shown in this script:
SQL> connect HR/globalguideline
Connected.
SQL> CREATE TABLE emp_dept_10
2 AS SELECT * FROM employees WHERE department_id=10;
Table created.
SQL> DROP TABLE emp_dept_10;
Table dropped.
Be careful, when you use the DROP TABLE statement. All data rows are gone too.
