How to get data using single select query
I'm created two table first one is test1 and second one is test2.
In first table one field is id and in second table one field is id.
in first table two data/value insert 1 and 2 and second table four data/value insert 1, 2, 3 and 4
I want to access only 3 and 4 data with use join key
Is this possible to get data using single select query.

SELECT table2.* FROM table2 LEFT JOIN table1 ON table2.id = table1.id WHERE table1.id IS NULL
SELECT * FROM table2 WHERE id NOT IN ( SELECT id FROM table1 )
