Question

I have a two tables, one that contains basic resource info, with columns and values like:

And a separate table of exta associated values with columns and data like:

What I am trying to do is write a SQL query that will join both and produce a result that is ordered by the “order” key, like so:

I am not sure how to make my join work so that I can both pull the location values and then SORT by the order values from that same table.

And before you ask, no I can’t redesign the db schema, I have to work with this. Any help greatly appreciated!

Answer 1

Try this

SELECT t1.RESOURCE_NO
       ,t1.NAME
       ,t2.VALUE
       ,t3.VALUE -- Included so that you can "see" the value
  FROM table1 t1
 INNER JOIN table2 t2
    ON t1.RESOURCE_NO = t2.RESOURCE_NO AND t2.[KEY] = 'location'
 INNER JOIN table2 t3
    ON t1.RESOURCE_NO = t3.RESOURCE_NO AND t3.[KEY] = 'order'
 ORDER BY t3.VALUE ASC
