Question

我目前正在使用表格列运行一些查询： unit_cost_cents, quantity_submitted, quantity_accepted

我想获得COST百分比和单位百分比。

SELECT
  SUM(CAST(unit_cost_cents * quantity_submitted / 100.00 AS MONEY)) AS submitted,
  SUM(CAST(unit_cost_cents * quantity_accepted / 100.00 AS MONEY)) AS accepted,
  accepted / submitted AS percent_dollars_accepted,
  quantity_submitted,
  quantity_accepted,
  quantity_submitted / quantity_accepted AS percent_units_accepted

结果不是预期的结果。

回答我自己的问题，继续我的回答我很满意：）

必须除以每个的总和：

  SELECT
    (DATE_TRUNC('month', (delivery_window_start::timestamptz - INTERVAL '0 second') AT TIME ZONE 'Etc/UTC') + INTERVAL '0 second') AT TIME ZONE 'Etc/UTC' AS month,
    SUM(CAST(unit_cost_cents * quantity_submitted / 100.00 AS MONEY)) AS "Submitted",
    SUM(CAST(unit_cost_cents * quantity_accepted / 100.00 AS MONEY)) AS "Accepted",
    SUM(CAST(unit_cost_cents * (quantity_submitted - quantity_accepted) / 100.00 AS MONEY)) AS "Not Accepted",
    (SUM(unit_cost_cents * quantity_accepted)::float / SUM(unit_cost_cents * quantity_submitted)::float * 100)::numeric(7,2) AS "Confirmation Rate",
    (SUM(unit_cost_cents * (quantity_submitted - quantity_accepted))::float / SUM(unit_cost_cents * quantity_submitted)::float * 100)::numeric(7,2) AS "Cancellation Rate",
    SUM(quantity_submitted) as "Quantity Submitted",
    SUM(quantity_accepted) as "Quantity Accepted",
    SUM(quantity_submitted - quantity_accepted) as "Quantity Not Accepted",
    (SUM(quantity_accepted)::decimal / SUM(quantity_submitted)::decimal * 100)::numeric(7,2) as "Confirmation Rate(Units)",
    (SUM(quantity_submitted - quantity_accepted)::decimal / SUM(quantity_submitted)::decimal * 100)::numeric(7,2) as "Cancellation Rate(Units)"
  FROM account_purchase_orders
  WHERE account_purchase_orders.account_id = #{account_id}
  GROUP BY month
  ORDER BY month ASC

postgresql计算总和的百分比
