sqlite LEFT OUTER JOIN multiple tables

Question

In this example we have 3 related tables on a SQLite database:

CREATE TABLE test1 (
    c1 integer,
    primary key (c1)
);
CREATE TABLE test2 (
    c1 integer,
         


        

Answer 1

This is a simple misplacement of your ON statement. This conforms to SQL standard:

SELECT * 
FROM test1 a 
LEFT OUTER JOIN test2 b ON b.c1=a.c1 
LEFT OUTER JOIN test3 c ON c.c2=b.c2 

This is explained in further depth here.
