下面的查询使用下面的查询格式找到了一个 id，但似乎我已经为所有列建立了索引，但执行时间在 54.3 秒 - 1.2 分钟之间。接下来我可以尝试什么？
查询:
select

最佳答案
重新安排您的查询，您会得到这个...
SELECT
op.ord_prod_id
FROM
account AS a
INNER JOIN
service AS s
ON s.acct_id = a.acct_id
INNER JOIN
ordered_product AS op
ON op.serv_id = s.serv_id
INNER JOIN
acct_order_item AS aoi
ON aoi.ord_prod_id = op.ord_prod_id
INNER JOIN
acct_order AS ao
ON aoi.order_id = ao.order_id
INNER JOIN
payment_method AS pm
ON ao.pay_meth_id = pm.pay_method_id
INNER JOIN
payment_type AS pt
ON pm.type_id = pt.id
WHERE
a.bu_id = 103
AND op.type IN (1,2)
AND op.validity_end_date < '2022-09-18 11:24:08 Etc/GMT'
AND op.validity_end_date >= '2022-09-18 00:00:00 Etc/GMT'
AND op.acct_status_id = 1
AND op.is_Renewable = 'T'
AND pt.description = 'Levis'
ORDER BY
op.validity_end_date ASC
这在我看来是错误的，但如果没有数据库模式我就无法判断。
这就是为什么我认为这是错误的......
- 获取
bu_id = 103的所有账户 - 获取所有这些帐户的服务(同一服务可能出现多次)
- 获取与这些服务关联的所有订购产品无论帐户
我强烈怀疑 acct_order 有一个 acct_id 列，这可能会启用类似这样的东西......
SELECT
op.ord_prod_id
FROM
account AS a
INNER JOIN
acct_order AS ao
ON ao.acct_id = a.acct_id
INNER JOIN
payment_method AS pm
ON pm.pay_method_id = ao.pay_meth_id
INNER JOIN
payment_type AS pt
ON pt.id = pm.type_id
INNER JOIN
acct_order_item AS aoi
ON aoi.order_id = ao.order_id
INNER JOIN
ordered_product AS op
ON op.ord_prod_id = aoi.ord_prod_id
--
-- No need to join on service now
--
WHERE
a.bu_id = 103
AND pt.description = 'Levis'
AND op.type IN (1,2)
AND op.acct_status_id = 1
AND op.is_Renewable = 'T'
AND op.validity_end_date >= '2022-09-18 00:00:00 Etc/GMT'
AND op.validity_end_date < '2022-09-18 11:24:08 Etc/GMT'
ORDER BY
op.validity_end_date ASC
仅此一项就可能会减少正在处理的行数，并深入了解您想要的索引，可能是...
account (bu_id, acct_id)
acct_order (acct_id, pay_meth_id, order_id)
payment_method (pay_method_id, type_id) or (type_id, pay_method_id)
payment_type (id, description) or (description, id)
acct_order_item (order_id, ord_prod_id)
ordered_product (type, acct_status_id, is_renewable, validity_end_date, ord_prod_id)
您还应该修复 WHERE 子句中使用的日期文字。
无论哪种方式，如果您想要更明确的响应，您需要包含这些表的完整架构，包括索引和外键(以验证您的连接)以及行数、基数等(以指导您索引创建、性能调整等)。
