Join postgres table on two columns?

will help you I can't find a straightforward answer. My query is spitting out the wrong result, and I think it's because it's not seeing the "AND" as an actual join. , This is possible:

Does that help I think your confusing from clause originates from the fact that you want the column default to be 12. To avoid that just declare the default when adding the column
alter table mydb.mortgageloans
add column OriginalHPI varchar(130) default '12';

update edp_data.rmb_loan a
set OriginalHPI = (
    case substring(a.edcode::text, 5, 2)
        when 'NL' then c.nl
        when 'BE' then c.be
        when 'ES' then c.es
        when 'FR' then c.fr
        when 'IT' then c.IT
        when 'DE' then c.de
        when 'IE' then c.ie
        else 12
    end)::numeric
from edp_data.hpi c
where a.ar55 = c.period

this one helps. I have a table that looks like this , Subqueries:
select x1.*, y2.y
from 
(
    select years, type, value as x
    from MyTable
    where x = 'true'
) x1
left join
(
    select years, type, value as y
    from MyTable
    where y = 'true'
) y2
on x1.years = y2.years
and x1.type = y2.type

In postgres, what is the best way to do an AND with a join table?

To fix the issue you can do I have different categories of user, and a join table that allows users to be in more than one category. My join table is called categories_users and it consists of a user_id and a category_id. , Just join with the same table twice (using aliases):
SELECT u.*
    FROM users u
    JOIN categories_users cu1 ON cu1.user_id = u.id
    JOIN categories_users cu2 ON cu2.user_id = u.id
    WHERE cu1.category_id = 1 AND cu2.category_id = 2

Hope this helps You need to convert the time and date value that you have in different columns (why?) to a single timestamp in order to be able to join on a timestamp column.
Adding a time value on a date value returns a timestamp, so you can use:
ON (TOTALIZER_METER_READINGS.date + TOTALIZER_METER_READINGS.time) = tt.mints
select distinct TOTALIZER_METER_READINGS.date + TOTALIZER_METER_READINGS.time
