Oracle Database Interview Question:
How To Empty Your Oracle Recycle Bin?
Submitted by: AdministratorIf your recycle bin is full, or you just want to clean your recycle bin to get rid of all the dropped tables, you can empty it by using the PURGE statement in two formats:
* PURGE RECYCLEBIN - Removes all dropped tables from your recycle bin.
* PURGE TABLE table_name - Removes the specified table from your recycle bin.
Here is an example script on how to use the PURGE statement:
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.
SQL> CREATE TABLE emp_dept_90
2 AS SELECT * FROM employees WHERE department_id=90;
Table created.
SQL> DROP TABLE emp_dept_90;
Table dropped.
SQL> SELECT COUNT(*) FROM recyclebin;
COUNT(*)
----------
5
SQL> PURGE TABLE emp_dept_90;
Table purged.
SQL> SELECT COUNT(*) FROM recyclebin;
COUNT(*)
----------
4
SQL> PURGE RECYCLEBIN;
Recyclebin purged.
SQL> SELECT COUNT(*) FROM recyclebin;
