Question

Please give a brief idea about SQL.

Answer 1

SQL Stands for : Structured Query Language
It's a statement to deal with the DataBase
I mean : getting , Inserting , updating , .... data from DB
you can also create a new database or create a table in an existing DB
I consists of two main parts :
DML : to deal with the data in the table (Data Manipulating Language )
DDL: to deal with the whole table or the whole database (Data Definition Language)
There are other parts : DCL , TCL but as a beginner you need only DML and DDL
