5   Jane    NULL    NULL
6   Bonnie  5       4
7   Bill    5       4

SELECT t.ID, t.Name, m.Name, f.Name
FROM your_table t
INNER JOIN your_table m ON m.ID = t.Mother
INNER JOIN your_table f ON f.ID = t.Father

Use LEFT JOIN

if you want to include entries without Mother

and / or Father

nodes:



SELECT t.ID, t.Name, ISNULL(m.Name, 'Orphan') Mother, ISNULL(f.Name, 'Orphan') Father
FROM your_table t
LEFT JOIN your_table m ON m.ID = t.Mother
LEFT JOIN your_table f ON f.ID = t.Father

try something like this:



select 
    p.id, p.name, p1.name as mother, p2.name as father
from people p
inner join people p1 on p1.id = p.mother
inner join people p2 on p2.id = p.father

Select "Request" 

SELECT A.*    
FROM tbl A   
    ,tbl M    
    ,tbl F    
WHERE A.Mother = M.ID     
    AND A.Father = F.ID

without internal connection.
