Finding and displaying duplicate values using WHERE IN to compare two values

Question

I have a MYSQL database where I would like to compare duplicated values based on two values in a column. For Example

Database

field_one | field_two | field_three 
------------------------------------
aaa       | 123       | no1
bbb       | 456       | no1
aaa       | 123       | no2
ccc       | 456       | no3 
aaa       | 123       | no3

I would like to return these results

field_one | field_two | field_three 
------------------------------------
aaa       | 123       | no1
aaa       | 123       | no2

Here is the query I've been using but I'm not sure how to get my desired result. When I run the query in phpMyAdmin my browser just gets stuck. My database is also large too.

SELECT * FROM table_name WHERE field_three IN (SELECT field_one, field_two FROM table_name WHERE field_three IN ('no1', 'no2') HAVING COUNT(*) > 1)

Thanks

SOLVED

I just changed WHERE @Gordon Linoff 's from query.

select t.*
from table_name t join
     (select field_one, field_two
      from table_name t
      group by field_one, field_two
      having count(*) = 2   -- or do you mean >= 2?
     ) tsum
     on t.field_one = tsum.field_one and t.field_two = tsum.field_two WHERE field3 IN ('no1', 'no2')

I think you want this:

select t.*
from t join
     (select field_one, field_two
      from t
      group by field_one, field_two
      having count(*) = 2   -- or do you mean >= 2?
     ) tsum
     on t.field_one = tsum.field_one and t.field_two = tsum.field_two

The subquery finds the duplicates based on the first two columns. The outer query returns the original rows.

If you want duplicates relative to another value, then add that condition to the subquery:

select t.*
from t join
     (select field_one, field_two
      from t
      where field3 = 'no1' -- or whatever you want to set it to
      group by field_one, field_two
      having count(*) = 2   -- or do you mean >= 2?
     ) tsum
     on t.field_one = tsum.field_one and t.field_two = tsum.field_two
