Помогите, пж, решить задачу по сортировке в sql: Please return one row per vendor, which represents the vendor's oldest invoice (the one with the earliest date). Each row returned should include the following columns: key T1.vendor_id= T2.vendor_id ## - "vendor_name" table T1 ## - "invoice_number" table T2 ## - "invoice_date" table T2 ## - "invoice_total" table T2 Please sort the result set by "vendor_name" in ascending order. Спасибо!!! ... |
