If you query aggregate values like Sum on a table, you will get back meaningful individual row values _only_ for fields which you Group By, so "table2.* makes no sense here. So if the joins are to be on field1, and if you want to Group your Sums also By field1, your query would look like this: SELECT table1.*, SUM(table2.field3), SUM(table2.field4) FROM table1 INNER JOIN table2 USING (field1) INNER JOIN table3 USING (field1) GROUP BY table.field1; PB ----- xtcsuk wrote: 3 tables:table1 -> table2 (one to many) table2 -> table3 (one to one) [designed like this] how to achieve this? select table1.*, table2.*, table3.*, sum(table2.field3), sum(table2.field4) from table1, table2, table3 where table1.field1 = table2.field1 and table2.field1 = table3.field1 regards |
