Query Link Table SQL

Question

I am having trouble wrapping my head around a simple query. I have a Link table like this:

+----------+----------+
| SourceID | TargetID |
+----------+----------+
| 1        | 2        |
+----------+----------+
| 1        | 3        |
+----------+----------+
| 3        | 4        |
+----------+----------+
| 3        | 5        |
+----------+----------+

And a table of Names

+----------+----------+
| ID       | Name     |
+----------+----------+
| 1        | Mitch    |
+----------+----------+
| 2        | Cheryl   |
+----------+----------+
| 3        | Sue      |
+----------+----------+
| 4        | Harry    |
+----------+----------+
| 5        | Bob      |
+----------+----------+

And I desire output like so. Structured just like the link table, but with the names instead.

+------------+------------+
| SourceName | TargetName |
+------------+------------+
| Mitch      | Cheryl     |
+------------+------------+
| Mitch      | Sue        |
+------------+------------+
| Sue        | Harry      |
+------------+------------+
| Sue        | Bob        |
+------------+------------+

Thanks for the help.

Answer 1

You have to join the names table twice with different aliases. Change the join to left join if the link table will have id's that are not in names .

Fiddle

select t1.name as sourcename, t3.name as targetname
from link t2
join names t1 on t1.id = t2.sourceid
join names t3 on t3.id = t2.targetid
