将子查询

Question

我有以下查询：

SELECT l.id, 
(SELECT amount FROM lead_status WHERE lead_id = l.id AND buyer = 'BUYER_PROXY') AS our_bid, 
(SELECT amount FROM lead_status WHERE lead_id = l.id AND buyer != 'BUYER_PROXY' AND discriminator='AUTO_PING' ORDER BY amount DESC LIMIT 1) AS best_bid, 
(SELECT amount FROM lead_status WHERE lead_id = l.id AND discriminator = 'AUTO_POST' AND winner = 1 ORDER BY amount DESC LIMIT 1) AS final_sold_amount, 
(SELECT buyer FROM lead_status WHERE lead_id = l.id AND discriminator = 'AUTO_POST' AND winner = 1 ORDER BY amount DESC LIMIT 1) AS buyer, 
(SELECT COUNT(*) FROM vehicles WHERE lead_id = l.id) AS number_of_vehicles FROM leads AS l, 
co.first_name, co.last_name, co.email, co.state, co.credit_type, ca.make, ca.model, co.owns_home, 
co.months_in_residence, a.injury, a.at_fault, d.gender_type, d.license_valid, d.license_obtained_age, 
d.education_level, d.license_revoked_in_last_five_years, TIME(l.create_date), rc.coverage_type 
FROM leads AS l 
LEFT JOIN contacts AS co ON l.id = co.lead_id 
LEFT JOIN vehicles AS v ON v.lead_id = l.id 
LEFT JOIN cars AS ca ON ca.id = v.car_id 
LEFT JOIN drivers AS d ON d.lead_id = l.id 
LEFT JOIN accidents AS a ON d.id = a.driver_id 
LEFT JOIN requested_coverage AS rc ON rc.lead_id = l.id 
WHERE l.state = 'ACCEPTED' 
AND (SELECT buyer FROM lead_status WHERE lead_id = l.id AND discriminator = 'AUTO_POST' AND winner = 1 ORDER BY amount DESC LIMIT 1) != 'TEST' 
AND DATE(l.create_date) > '2011-12-01' 

我试图添加其他子查询，但每次我把它添加到子查询，我得到一个错误的结束，当我运行命令。

这是我想要添加的。

不断收到错误消息当我运行：

SELECT l.id, 
(SELECT amount FROM lead_status WHERE lead_id = l.id AND buyer = 'BUYER_PROXY') AS our_bid, 
(SELECT amount FROM lead_status WHERE lead_id = l.id AND buyer != 'BUYER_PROXY' AND discriminator='AUTO_PING' ORDER BY amount DESC LIMIT 1) AS best_bid, 
(SELECT amount FROM lead_status WHERE lead_id = l.id AND discriminator = 'AUTO_POST' AND winner = 1 ORDER BY amount DESC LIMIT 1) AS final_sold_amount, 
(SELECT buyer FROM lead_status WHERE lead_id = l.id AND discriminator = 'AUTO_POST' AND winner = 1 ORDER BY amount DESC LIMIT 1) AS buyer, 
(SELECT COUNT(*) FROM vehicles WHERE lead_id = l.id) AS number_of_vehicles FROM leads AS l, 
co.first_name, co.last_name, co.email, co.state, co.credit_type, ca.make, ca.model, co.owns_home,

Answer 1

你有两个FROM leads AS l

(SELECT COUNT(*) FROM vehicles WHERE lead_id = l.id) AS number_of_vehicles FROM leads AS l, 
/* ------------------------------------------------------------------------------^^^^^^^^*/ 
co.first_name, co.last_name, co.email, co.state, co.credit_type, ca.make, ca.model, co.owns_home, 
co.months_in_residence, a.injury, a.at_fault, d.gender_type, d.license_valid, d.license_obtained_age, 
d.education_level, d.license_revoked_in_last_five_years, TIME(l.create_date), rc.coverage_type 
FROM leads AS l 
/*---^^^^^^^^^^^^*/ 

第一个不应该存在。

... 
(SELECT COUNT(*) FROM vehicles WHERE lead_id = l.id) AS number_of_vehicles, 
co.first_name, co.last_name, co.email, co.state, co.credit_type, ca.make, ca.model, co.owns_home, 
co.months_in_residence, a.injury, a.at_fault, d.gender_type, d.license_valid, d.license_obtained_age, 
d.education_level, d.license_revoked_in_last_five_years, TIME(l.create_date), rc.coverage_type 
FROM leads AS l
