  1. Q. What is SQL and also describe types of SQL statements? • SQL stands for Structured Query Language. SQL is a language used to communicate with the server to access, manipulate and control data. • There are 5 different types of SQL statements. • Data Retrieval: SELECT • Data Manipulation Language (DML): INSERT, UPDATE, DELETE, MERGE • Data Definition Language (DDL): CREATE, ALTER, DROP, RENAME, TRUNCATE. • Transaction Control Statements: COMMIT, ROLLBACK, SAVEPOINT • Data Control Language (DCL): GRANT, REVOKE

  2. 2. What is an alias in SQL statements? • Alias is a user-defined alternative name given to the column or table. By default column alias headings appear in upper case. Enclose the alias in a double quotation marks (“ “) to make it case sensitive. “AS” Keyword before the alias name makes the SELECT clause easier to read. • For ex: Select empname AS name from employee; (Here AS is a keyword and “name” is an alias).
