DDL stand for Data Definition Language. It is managing properties and attributes of database.DDL commands are used to define the structure that holds the dataThese commands are auto-committed i.e. changes done by the DDL commands on the database are saved permanently.
Some DDL commands are:

  • ALTER for alteration.
  • Truncate to delete data from the table.
  • DROP to drop a table.
  • RENAME to rename a table.
