What is DDL?
Data Definition Language (DDL) is a subset of SQL used to define and manage database structures. Common DDL commands include:
- CREATE - Creates new database objects (tables, views, indexes, etc.)
- ALTER - Modifies existing database objects
- DROP - Deletes database objects
- TRUNCATE - Removes all records from a table
- RENAME - Renames database objects
DDL files typically contain the complete schema definition of a database.
