SQL Commands

SQL commands are classified into four groups on the basis of their nature.

  • DDL (Data Definition Language)
  • DML (Data Manipulation Language)
  • DCL (Data Control Language)
  • DQL (Data Query Language)
NOTE: This symbol ‘[ ] ‘indicates optional. SQL is not a case sensitive language.
