多表聯合查詢SQL語句

 $tempSQL = "SELECT portfolio.bmi_no as bmi_no,portfolio.title1 as title1,portfolio.lname1 as lname1,portfolio.fname1 as fname1,member.login_name as login_id, portfolio.lname2 as lname2,portfolio.fname2 as fname2,portfolio.principle as principle,portfolio.email as email,portfolio.policy_no as policy_no,portfolio_file.en_file as en_file,portfolio_file.en_enable as en_enable,policy_status.problem_type as problem_type

解釋之後的SQL語句：

SELECT portfolio.bmi_no AS bmi_no, portfolio.title1 AS title1, portfolio.lname1 AS lname1, portfolio.fname1 AS fname1, member.login_name AS login_id, portfolio.lname2 AS lname2, portfolio.fname2 AS fname2, portfolio.principle AS principle, portfolio.email AS email, portfolio.policy_no AS policy_no, portfolio_file.en_file AS en_file, portfolio_file.en_enable AS en_enable, policy_status.problem_type AS problem_type
FROM `portfolio`
LEFT JOIN `member` ON portfolio.full_name = member.full_name
AND portfolio.dob = member.dob
LEFT JOIN `policy_status` ON portfolio.policy_no = policy_status.policy_no
AND policy_status.is_live =1
LEFT JOIN `policy_fund` ON portfolio.principle = policy_fund.principle
AND portfolio.policy_no = policy_fund.policy_no
AND policy_fund.is_live =1
LEFT JOIN `portfolio_file` ON portfolio.bmi_no = portfolio_file.bmi_no
AND portfolio_file.year = '2011'
