Answer 2

这样的东西？

SELECT 
  member.lastname,
  member.firstname
  membershipstatustype.memberstatustype_name
  membershiptype.membershiptype_name
  memberstomships.membertomship_lastdate
FROM 
  member
  INNER JOIN memberstomships ON member .member_id = memberstomships.memberid
  INNER JOIN membershipstatustype ON memberstomships.membershipstatusid = membershipstatustype.membershipstatusid 
  INNER JOIN membershiptype ON membershipstatustype.membershiptype_name = membershiptype.membershiptype_name 
WHERE
  UCASE(memberstomships.membertomship_paymentmethod) = 'MONEY'

Answer 3

试试这个，

SELECT  Member.LastName,  Memebr.FirstName, memberstatustype_name, membershiptype_name, membertomship_lastdate,
FROM Members
 LEFT JOIN  Memberstomships
ON Memberstomships.member_Id = Members .member_Id
LEFT JOIN  membershipstatustype
ON membershipstatustype .membershipstatusid = Memberstomships.membershipstatusid 
LEFT JOIN membershipoption 
ON membershipoption .membershipoptionid = memberstomships.membershipoptionid 
LEFT JOIN  membershiptype
ON membershipstatustype .membershiptype_id = membershipoption .membershiptype_id
WHERE membertomship_paymentmethod =  'money'

Answer 4

如果您使用 LIKE 运算符来比较字符串，那就更好了。

P.S。您的表格和字段名称真的很难读。纠正它们。
