Question

+----+--------+--------+
| id |  name  | parent |
+----+--------+--------+
| 1  | AA     | 0      |
| 2  | AB     | 1      |
+----+--------+--------+

How do I get the name of id 1 given that I have the id 2 in one sql statement?
i.e. Rather than selecting the parent then doing another select to get the name from that id.

To clarify, I have the id of 2 and I need to get the name of its parent.

I’m sure this is very simple – I just can’t work it out!

Answer 1

Something like this: (haven’t tested obviously)

SELECT second.name 
FROM
TableName first Join TableName second
ON first.parent = second.id
where first.id = 1
