Hi Sugitha, print 'Employee Id = ' + cast(@EmpId as nvarchar(2)) What it says abt. Take @EmpId value is 123 , The abouve line will going to print "Employee Id = 12" Because the nvarchar has set it max length 2. If your employee id 123, the length will be three, it will take first two characters and will display 12 wil concatenation of "Employee id =" text. Then "cast(@EmpId as nvarchar(2)) converting @empid value as varchar data type.
