Answer 1

You have a typo, Datedife -> Datediff. Try:

select Datediff(year,'2008-06-05','2010-06-05') AS XXX

Answer 2

Its DATEDIFF

 com.CommandText = "select DATEDIFF(year,'2008-06-05','2010-06-05') AS XXX";

        da = new SqlDataAdapter(com);
        dt = new DataTable();
        da.Fill(dt);

Answer 3

使用DATEDIFF

com.CommandText = "select DATEDIFF(year,'2008-06-05','2010-06-05') AS XXX";

Answer 4

use DATEDIFF(instead of DATEDIFE its a wrong keyword)

There is a spelling mistake in your query

SELECT DATEDIFF(YEAR,'2008-06-05','2010-06-05') AS XXX
