Use the DROP SEQUENCE statement to remove a sequence from the database.

You can also use this statement to restart a sequence by dropping and then re-creating it. For example, if you have a sequence with a current value of 150 and you would like to restart the sequence with a value of 27, then you can drop the sequence and then re-create it with the same name and a START WITH value of 27.

The sequence must be in your own schema or you must have the DROP ANY SEQUENCE system privilege.



Specify the schema containing the sequence. If you omit schema, then Oracle Database assumes the sequence is in your own schema.


Specify the name of the sequence to be dropped.


Dropping a Sequence: Example The following statement drops the sequence customers_seq owned by the user oe, which was created in "Creating a Sequence: Example". To issue this statement, you must either be connected as user oe or have the DROP ANY SEQUENCE system privilege:

DROP SEQUENCE oe.customers_seq;
