25.6k

  • DDL (Data Definition Language) instructions are used to create and change database objects.
  • Creates things.
  • Alters the state of objects.
  • Objects are deleted when you drop them.
  • Truncate: This command deletes all data in a table.

DROP is a Data Definition Language command, whereas DELETE is a Data Manipulation Language command. The difference between DELETE and DROP is that DELETE removes tuples from a table while DROP removes the entire schema, table, domain, or constraints from the database.

The DELETE command is used to remove rows from a table (one or more). This command is used to delete all of the rows in a table. 2. It's a DML command (Data Manipulation Language).
