在实体框架中执行原始SQL不会返回结果集

Question

I am using the following query. It returns 5 rows in a list but all the elements in the list are null .

public class TempClass
{
    public int SID { get; set; }
    public string SNAME { get; set; }
    public string SAGE { get; set; }
}

var i = _dbContext.Database
                  .SqlQuery<TempClass>("select ID, NAME, AGE from eis_hierarchy")
                  .ToList();

What I am doing wrong?

Answer 1

Try making the columns returned in the SQL query match the property names in the class you're trying to return:

var i = _dbContext.Database
    .SqlQuery<TempClass>("select ID as SID, NAME as SNAME, AGE as SAGE from eis_hierarchy")
    .ToList();
