Help with joining a table twice

I have two tables where the first one relates to the second one from two fields, and I'm not sure how to set up a query properly. Tables look like:

TableA {
  main_code
  related_code
}

TableB {
  code
  name
}

Open in new window


I want to select the code and name for both the main and related code, so the output would have columns like this:

main.code | main.name | related.code | related.name

Could someone point me in the right direction?

Not sure exactly which fields are supposed to match in the tables, but try this

select ta.main_code, tb1.name, ta.related_code, tb2.name
from tablea ta
inner join tableb tb1 on tb1.code = ta.main_code
inner join tableb tb2 on tb2.code = ta.related_code

Sweet! Thank you for the quick reply, dkrollCTN.

I swapped out the table and field names for those in our database, and it does exactly what I needed.
