how to get the next autoincrement value in sql

Question

I am creating a winform application in c#.and using sql database.

I have one table, employee_master, which has columns like Id, name, address

Answer 1

the max(id) will get you maximum number in the list pf employee_master

e.g. id = 10, 20, 100 so max will get you 100

But when you delete the record it must have been not 100

So you still get 100 back

One important reason for me to say this might be the issue because you are not using order by id in your query
