C# '；DATEDIFE'；不是可识别的内置函数名

我在下面的代码有问题，有人能帮我吗？ 显示（DATEDIFE'不是可识别的内置函数名。）错误

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

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

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

您的查询中有拼写错误

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

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