I have the following query: SELECT i.title, j.title FROM table1 i JOIN table2 j

  • 0

I have the following query:

SELECT i.title, j.title FROM table1 i JOIN table2 j ON i.id = j.table1_id

Now what I would like is to select i.title AS title if i.title exists, otherwise use j.title AS title.

Any thoughts?

    use LEFT JOIN and COALESCE

    SELECT COALESCE(i.title, j.title) title 
FROM   items i 
       LEFT JOIN table j 
           ON i.id = j.items_id
