Hello, we aware strange behaviour of H2 when quering COUNT with subquery.
Prepare table: CREATE TABLE Foo ( id INT PRIMARY KEY AUTO_INCREMENT, fieldName VARCHAR(30) NOT NULL, ); Test simple query (works fine): SELECT * from Foo as F1 INNER JOIN Foo F2 on F1.id = F2.id Test same query with count: SELECT count(*) FROM ( SELECT * from Foo as F1 INNER JOIN Foo F2 on F1.id = F2.id ) q; Got error: [42S21][42121] Duplicate column name "ID"; SQL statement: select count(*) FROM ( SELECT * from Foo as F1 INNER JOIN Foo F2 on F1.id = F2.id) q [42121-192] -- You received this message because you are subscribed to the Google Groups "H2 Database" group.
