Answer 1

Take a look at this example

INSERT INTO Employee (EmpName,Emp_level,Emp_Sal) VALUES ('Chris', 25B, 54000);

SELECT Emp_id FROM jobs Employee Emp_id = @@IDENTITY;

for More info see this Identity(SQl Authority)

and this Identity(MSDN))

as an alternative solution to Identity one could use MAX() as well a simple syntax would be like SELECT MAX(Emp_id) FROM Employee ; Hope this Helps

Answer 2

SELECT Top1 Emp_id FROM jobs Employee Emp_id = @@IDENTITY; 

SELECT Max Emp_id FROM jobs Employee Emp_id = @@IDENTITY;
