#sql 

Hi All,
My name is Ankit Shrivastava and I am a Data Engineer.
Today this #vlog is regarding #sql
What is the difference between WHERE & AND clause with LEFT/RIGHT join ?
What is happening when we use same condition with WHERE clause & AND clause with JOINS and also I am discussing INNER join + WHERE clause is giving same result with LEFT join + WHERE clause
Is output is going to be same ?
select * from emp e left join dept d on e.dept_id = d.dept_id WHERE e.salary = 1000;
select * from emp e left join dept d on e.dept_id = d.dept_id AND e.salary = 1000;
Please find the DDL for practice:-
create table emp (emp_id int, emp_name varchar(20),dept_id int, salary int);
insert into emp values(100,'Ankit',1,1000);
insert into emp values(101,'Saurabh',1,2000);
insert into emp values(102,'Kushal',2,3000);
insert into emp values(103,'Farhan',2,5000);
insert into emp values(104,'Varun',3,6000);
create table dept (dept_id int, dept varchar(20));
insert into dept values (1,'IT');
insert into dept values (2,'HR');
insert into dept values (3,'SALES');
