请用一条SQL语句完成以下查询任务:
综合客户表(client)、资产表(property)、理财产品表(finances_product)、保险表(insurance)和基金表(fund),列出客户的名称、身份证号以及投资总金额(即投资本金,每笔投资金额=商品数量*该产品每份金额),注意投资金额按类型需查询不同的表,
投资总金额是客户购买的各类(理财,保险,基金)资产投资金额的总和,总金额命名为total_amount。查询结果按总金额降序排序。
基于new bing部分指引作答:
以下是一条SQL语句可以完成您的查询任务:
SELECT c.name, c.id_card_number,
COALESCE(SUM(p.quantity * f.amount_per_unit), 0)
+ COALESCE(SUM(p.quantity * i.amount_per_unit), 0)
+ COALESCE(SUM(p.quantity * fu.amount_per_unit), 0) AS total_amount
FROM client c
LEFT JOIN property p ON c.client_id = p.client_id
LEFT JOIN finances_product f ON p.property_type = '理财' AND p.product_id = f.product_id
LEFT JOIN insurance i ON p.property_type = '保险' AND p.product_id = i.product_id
LEFT JOIN fund fu ON p.property_type = '基金' AND p.product_id = fu.product_id
GROUP BY c.name, c.id_card_number
ORDER BY total_amount DESC;
上述SQL语句中,通过使用左联接(LEFT JOIN)将客户表与资产表、理财产品表、保险表和基金表进行关联。根据资产类型(property_type)来判断关联哪个表,并计算每个类型的投资金额(quantity * amount_per_unit)。最后,使用聚合函数SUM对各项投资金额进行求和,并别名为total_amount。查询结果按照总金额(total_amount)降序排序。
请注意,在实际操作中,请将表名、字段名和条件适配您的数据库架构。
1、可以参考下面语句
SELECT
c.client_name,
c.identity_number,
COALESCE(SUM(fp.quantity * fp.unit_price), 0) AS total_amount
FROM
client c
LEFT JOIN
property p ON c.client_id = p.client_id
LEFT JOIN
finances_product fp ON c.client_id = fp.client_id
LEFT JOIN
insurance i ON c.client_id = i.client_id
LEFT JOIN
fund f ON c.client_id = f.client_id
GROUP BY
c.client_name,
c.identity_number
ORDER BY
total_amount DESC;
