using tuples in sql in clause

Question

Given a database like this:

BEGIN TRANSACTION;
CREATE TABLE aTable (
a STRING,
b STRING);
INSERT INTO aTable VALUES(\'one\',\'two\');
INSERT INTO aTable VALU         


        

Answer 1

Another alternative is to use concatenation to make your 2-tuple into a single field :

SELECT a,b FROM aTable
WHERE (aTable.a||'-'||aTable.b) IN
(SELECT (anotherTable.a || '-' || anotherTable.b FROM anotherTable);

...just be aware that bad things can happen if a or b contain the delimiter '-'
