What are the types of SQL languages?

Answer: SQL languages are classified into the following types:

Data definition language (DDL) is used to define or modify an object in a database, such as a table, an index, or a view.
Data manipulation language (DML) is used to perform operations on data in database tables, such as inserting, updating, querying, or deleting data.
Data control language (DCL) is used to set or change the permissions of database users or roles.
