Commit Command
A COMMIT command issued implicitly or explicitly permanently saves the DML statements issued previously
- An explicit COMMIT occurs when you enter a COMMIT statement
- an implicit COMMIT occurs when you exit client tools, such as SQL Developer. It also occurs if a DDL command, such as CREATE or ALTER TABLE, is issued. In other words, if a user adds several records to a table and then creates a new table, the records added before the DDL command is issued are committed automatically (implicitly).
