  2. Uses of SQL commands SQL commands can be used not just for searching the database but also to execute various other functions. Using SQL commands, you are able to create tables, add data to tables, or modify data, drop the table and even set aside permissions for users.

  3. The 4 categories of SQL commands • DDL (Data Definition Language) • DML (Data Manipulation Language) • TCL (Transaction Control Language) • DCL (Data Control Language)
