如何使用取消索引日期列优化 Sql 查询？

Question

我需要优化此查询，因为 creationDate 不是索引列。所以这需要时间。以下是查询：-

SELECT 
    quoteId as 'ID of the quote',
    requestType as 'Quote Type',
    type as 'New or Change',
    taskName as 'Quote Status',
    currency.currencyCode as 'Currency Code',
    customer.name as 'Customer Name(Contracting Party)',
    quote.contractingParty_customerId as 'Customer IC01(Contracting Party)',
    customer.salesCountryValue as 'Customer sales country',
    item.fpc_financeProductCodeId as 'fpc',
    opt.number as "option", 
    opt.pricingMonthlyAmount as "Monthly existing Charges(Eur).", 
    opt.pricingOneOffCharges as "Total One-off Charges(EUR)", 
    opt.customerLabel as "Customer Label",
    item.property as "service infomration"
FROM
pqto01.qto_quote quote inner join   
pqto01.qto_product_item item on quote.product_productId = item.productItems_productId  inner join 
pqto01.qto_option opt on opt.options_productItemId = item.productItemId inner join 
pqto01.qto_customer customer on  customer.customerId = quote.contractingParty_customerId inner join 
pqto01.qto_currency currency on quote.pricingCurrency1_currencyId = currency.currencyId 
where  quote.creationDate between ('2020-03-01' and '2020-03-10') and
(opt.pricingMonthlyAmount = 0 and opt.pricingOneOffCharges = 0);

如果我是运行没有 creationDate 的查询，那么它花费的时间更少，但是 creationDate 在 mysql 中花费的时间超过 30 秒。所以，无论如何我都可以在不索引 creationDate 列的情况下使其更快。我使用的数据库是我的 sql。谢谢。

opt 可能受益于这个综合指数：

INDEX(pricingOneOffCharges, pricingMonthlyAmount)
