Re: return records with more than one occurrences

Howdy, Tarsis.

Please try this out.

SELECT a.id, id_table1,a.name
FROM "Table2" a
NATURAL JOIN
(SELECT id_table1
"Table2"
GROUP BY id_table1
HAVING COUNT(*) > 1) b

Tell me if it worked or not, and if it didn't the errors/uncorrect results.

Best,
Oliveiros
