I don't really have any video or data links. But:
A:
LOAD * INLINE [
ID, Field1
1, 123
2, 456
3, 789
];
LEFT JOIN (A)
LOAD * INLINE [
ID, Field2
1, A
2, B
4, C
];
This LEFT join will generate:
ID, Field1, Field2
1, 123, A
2, 456, B
3, 789,
A RIGHT join would generate:
ID, Field1, Field2
1, 123, A
2, 456, B
4, , C
An INNER join would generate:
ID, Field1, Field2
1, 123, A
2, 456, B
An OUTER join would generate
ID, Field1, Field2
1, 123, A
2, 456, B
3, 789,
4, , C
A CONCATENATE would generate:
ID, Field1, Field2
1, 123,
2, 456,
3, 789,
1, , A
2, , B
4, , C
Hopefully I got all of those right.
