In this statement, First, you specify the name of the table from which you want to delete data. Second, you specify which row should be deleted by using the condition in the WHERE clause. If you omit the WHERE clause, the Oracle DELETE statement removes all rows from the table.

The default value can be literal value, an expression, or a SQL Function, such as SYSDATE.
