【问题描述】：

我有两条 sql 语句。

    SELECT
    sku_id,
    inventory_state,
    count() AS sumNum,
    sum(in_price) AS sumInPrice,
    sum(out_price) AS sumOutPrice
FROM
    imspc_inventory_lifecycle_bills_2021
WHERE
    sku_id IN (1422796349332701186, 1415500436516028417)
    AND inventory_state IN ('1', '5', '6')
    AND purchase_depart_id = 8
GROUP BY
    sku_id,
    inventory_state

和

    SELECT
    sku_id,
    inventory_state,
    count() AS sumNum,
    sum(in_price) AS sumInPrice,
    sum(out_price) AS sumOutPrice
FROM
    imspc_inventory_lifecycle_bills_2021
WHERE
    sku_id IN (1422796349332701186, 1415500436516028417)
    AND inventory_state IN ('1', '5', '6')
    AND purchase_depart_id = '8'
GROUP BY
    sku_id,
    inventory_state

purchase_depart_id 字段类型为 int64。 第一个 SQL 结果是enter image description here

第二个 SQL 结果是正确的。 是什么导致了这个问题？
