如何检索多个表并在MySQL中格式化它的一些行？

Question

我有以下3个表：

custom_data表：

+----+----------------------+ 
| id | name     | 
+----+----------------------+ 
| 13 | ACCOUNT NAME   | 
| 14 | ACCOUNT NO   | 
| 15 | ID NUMBER   | 
+----+----------------------+ 

custom_data_values表：

+----------------+-----------------+-----------+ 
| custom_data_id | value   | member_id | 
+----------------+-----------------+-----------+ 
|    13 | Ivy Jane Mosendi|  33 | 
|    14 | 2199030092  |  33 | 
|    15 | 25917781  |  33 | 
+----------------+-----------------+-----------+ 

成员表：

+----+----------------------------+ 
| id | name      | 
+----+----------------------------+ 
| 30 | John Doe     | 
| 31 | Willy Ong     | 
| 32 | James Reid     | 
| 33 | Ivy Jane Mosendi   | 
+----+----------------------------+ 

我想以下结果：

+----+------------------+------------------+-------------+-------------+ 
| id | name    | ACCOUNT NAME  | ACCOUNT NO | ID NUMBER | 
+----+------------------+------------------+-------------+-------------+ 
| 33 | Ivy Jane Mosendi | Ivy Jane Mosendi | 2199030092 | 25917781 | 
+----+------------------+------------------+-------------+-------------+ 

我怎样才能达到这个结果与一个MySQL查询？

我终于破解了它。谢谢所有

SELECT m.name 
     , MAX(CASE WHEN cf.name = 'ACCOUNT NAME' Then cfv.string_value END) As 'ACCOUNT NAME' 
     , MAX(CASE WHEN cf.name = 'ACCOUNT NO' Then cfv.string_value END) As 'ACCOUNT NO' 
     , MAX(CASE WHEN cf.name = 'ID NUMBER' Then cfv.string_value END) As 'ID NUMBER' 
    FROM custom_field_values cfv 
    INNER JOIN custom_fields cf 
     ON cf.id = cfv.field_id 
    INNER JOIN members m 
     ON m.id = cfv.member_id 
    WHERE m.id = 33
