I am using this query in 8.3beta4 (compiled from source) in MacOS X 10.5.1 SELECT webName,count(*) FROM contenitore NATURAL JOIN cartellino WHERE contenitore.tipo='e' GROUP BY webName; this is the result webName | count --------------------------------------------------+------- test palermo | 36679 Herbarium Camerinensis - CAME | 36679 Herbarium Universitatis Aeserniae - IS | 36679 Herbarium Universitatis Civitatis Perusii - PERU | 36679 Herbarium Anconitanum - ANC | 36679 Test database - São Paulo | 36679 Herbarium Universitatis Genuensis - GE | 36679 Herbarium Universitatis Senensis - SIENA | 36679 Segnalazioni Siena | 36679 Herbarium Aquilanum - AQUI | 36679 (10 rows) but 36679 is the total number of row of the table. The same query in 8.1.4 retrieves the aspected result (the number of elements for each webName). Is this a bug or a change in the semantic of SQL? thank you Edoardo -- Jabber: edoardopa@xxxxxxxxxxxxxxx tel: 075 9142766 ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
