Here the data type of <expression1> and <expression2> is some type of date, time, or datetime. The result is <expression2> - <expression1>.

Step 1

Open SQL server 2014 and create a table of employees,

  2.     [EmployeeId] [int] IDENTITY(1,1) NOT NULL,

  10. PRIMARY KEY CLUSTERED   
  11. (  
  12.     [EmployeeId] ASC  
  13. )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]  
  14. ) ON [PRIMARY]  
  15.
