Hi friends, here we come with some new topics that is based on Sql language.
Oracle is s software and their functionality is disscussed in older post. To work with Database we need a client to send request and accept responce. And to communicate with oracle server we need a language and that language is called SQL. SQL is initially developed by IBM and their name was SEQUEL.
SQL is structured Query Language. User communicates with oracle server by sending command and instruction , that instruction and command is called Query. A query is a command and instruction submitted to oracle server to perform operation on database.
