Related on 2 columns

[Anonymous]

I have two tables:
 Fisrt:

id	code	value
56786	_1	first_value
56786	_2	second_value
56786	_3	third_value
56786	_4	forth_value
56786	_5	fifth_value
56786	_6	sixth_value

Second:

id	code	value
56786	_3	third_value
35678	_4	forth_value
55567	_1	first_value

So, in first we apply 6 kinds of values per each person. But in second we got one chosen by person value per that person. How can I add any column from first table to second? Related on person_id and code.
It can be complicated, so, if smth is unclear, ask me please, because I find it hard to do it. Thank you!

Hi @Anonymous ,
you can concatenate both id and code columns and have both the tables related on that composite key. Then use RELATED() to add any column from the first table to the second.
