Question

I have the following 3 tables

table1

id    name
----------
1     john
2     dave
3     eve

table2

table1_id    table3_id
----------------------
   1            2            
   1            3
   1            5
   2            2
   2            3
   2            4
   3            1
   3            5

table3

id    title
------------
1     blue
2     orange
3     green
4     yellow
5     black

I’m trying to select each table1.name where table3.title = (blue OR orange) AND (green OR black)

so that the output is

name
----
john
dave

This is my query so far that won’t get this job done:

SELECT table1.name 
FROM table1 
JOIN table2 ON table1.id = table2.table1_id
JOIN table3 t1 ON table2.table3_id = t1.id
JOIN table3 t2 ON t1.title = t2.title
WHERE t1.title IN ('blue', 'orange')
AND t2.title IN ('green', 'black')

Any suggestions would be really appreciated!

UPDATE
One more question 🙂

How to select each table1.name where table3.title = (‘green’ AND ‘orange’ AND ‘black’ AND ‘…’)

Answer 1

If I’m getting your question right, you’re close:

SELECT table1.name
FROM table1 
JOIN table2 t1_link ON table1.id = t1_link.table1_id
JOIN table3 t1_data ON t1_link.table3_id = t1_data.id AND t1_data.title in ('blue', 'orange')
JOIN table2 t2_link ON table1.id = t2_link.table1_id
JOIN table3 t2_data ON t2_link.table3_id = t2_data.id AND t2_data.title in ('green', 'black')
