#1 SQL Crash Course | What is SQL? | SQL for beginners Part-1

SQL is a simple query language used for accessing, handling and managing data in relational databases. It is a non-procedural language. To solve a problem in 'SQL' you simply need to tell what you want.

Example :- Suppose we have an 'Employee' table and we want to fetch the record having age>50 and salary>2 Lacs, then we write the query as follows :

Select* from Employee where age>50 and salary>2,00,000;

Advantages :

1. Simple and easy to learn.
2. applications written in SQL can be easily ported across systems & network.
3. Results to be expected are well-defined.
4. It is independent of the way it is implemented internally.
