Wonderful lecture! quite easy to understand.
Explained very nicely sir.
there's a video missed about equi and non equi joins.. please upload it sir.. there's no discussion about non ansi joins of equi n non equi joins, these two topics are missed somehow..
Thank you so much, Nice explanation!
Can we use this statement instead of self join ?
Select e.* from EmpDetails e
where e.Salary in (select salary from empDetails group by salary having count(salary)>1)
I think we can do like thz after giveing where ename = smith we get total row details from that we can know salary was 8000 with that same where condition where salary = 8000 we can find other person details also who is haveing same salary that smith haveing . 😀
GREAT JOB SIR,VERY GOOD TEACHING

sir is it correct to say that non equi join is just like cross join except for the fact that the colums in which something is missing null is implemented???

sudhakar sir, plzs you explain store procedure of each part..
and how's different to function and also explain function.
Sel * from employeedetails where
Salary in (select salary from employeedetails where ENAME= "SMITH")
it should also work...
Thank you sir :)
Can anyone please suggest to me if I go through all 47 SQL server videos and practice 100% so do I get maximum knowledge on SQL server?
nice explanation..
Thanks for your time
Question : which employees are getting same salary. .
In this case... How we are giving static value as Smith...
Instead we can use groupBy salary and take count and filter when count > 1
am waiting for equi join and non equi join video class plz upload it sir
pls upload equi n non equi join
Expected Example Explanation with Self Referential Integrity Purpose: A FK referring to its own table PK.

😎👍🏽
You said ... we want to retrieve same employee salary from the table(don't give hint point). Why again u are taking Smith in this query..
I don't know sryyy
Yeah I think he just wanted to teach us how to use ALIAS...
The query can be written as below:
SELECT E.NAME, E.SALARY FROM EMPLOYE E, EMPLOYE A
WHERE E.SALARY=A.SALARY and E.EIDA.EID;
Hope it helps.
Thanks
But of we don't know the employee name
what if I don't know the employee name?
select * from empdetails e1 , empdetails e2
where e1.salary = e2.salary and e1.eide2.eid
@@tarunsirsath5110 Great
what if I don't know the employee name? u didnt explain;;;;;;;
select * from empdetails e1 , empdetails e2
where e1.salary = e2.salary and e1.eide2.eid
Where is the link for Equi join video ?
Instructor seems to be technically strong but weak in language. If he improves that then his videos would be more useful to many people.
SELECT * from table Where salary = 8000 should work
It works if you have information about the salary
The query below also works :
SELECT E.NAME, E.SALARY FROM EMPLOYE E, EMPLOYE A
WHERE E.SALARY=A.SALARY and E.EIDA.EID;
Before Class Video which got missed on Equi Join and Non Equi Join Link ua-cam.com/video/pmfATg5ciWQ/v-deo.html
Explanation is k.. But english must improve..
For this one small topic, why you have taken this much time..boss😭
if you explain like this than student will be crazy. LOL
