I avoided doing so, in order to highlight the insufficiency of just 2 left joins and a union, which is what i have seen so far recommended. Of course you could combine the two in a single query, without having to create a temp view.

Consider the 2 simple tables people1 and people2 below: id name ageįirst, we create a temporaty view, v_all, where we join with UNION the two opposite LEFT JOINS as below: CREATE TEMP VIEW v_all AS The code has been tested with SQLite version 3.32.2 It appears, that the UNION clause does also order the output via the flightNumber column. The SQLite statement above returns the expected result in one query. 1064 - You have an error in your SQL syntax check the manual that corresponds to your MariaDB server version for the right syntax to use near OUTER JOIN useraddresses ON ORDER by us at line 1 mysql mysql-5.

The following Venn diagram shows the expected output: For people, searching for an answer to emulate a Distinct Full Outer Join:ĭue to the fact, that SQLite does neither support a Full Outer Join, nor a Right Join, i had to emulate a distinct full outer join / an inverted inner join (however you might call it).
