¿Cómo diseñar una "vista" en MySQL que obtenga los resultados que estoy buscando?

Question

He conseguido crear una vista de algunos datos en mi base de datos MySQL, como a continuación:

mysql> CREATE VIEW phonelist AS 
    -> SELECT parent.parentID AS ParentID, 
    -> ParentPerson.firstName AS ParentFirstName, 
    -> ParentPerson.lastName AS ParentLastName, 
    -> ChildPerson.firstName AS PlayerFirstName, 
    -> ChildPerson.lastName AS PlayerLastName, 
    -> GuardianHomePhone.homeNumber AS GuardianHomePhone 
    -> FROM parent 
    -> JOIN player ON (parent.parentID IN (player.motherID, player.fatherID)) 
    -> JOIN person AS ParentPerson ON (ParentPerson.personID = parent.parentID) 
    -> JOIN person AS ChildPerson ON (ChildPerson.personID = player.playerID) 
    -> JOIN addressDetails AS GuardianHomePhone ON (GuardianHomePhone.personID = parent.parentID); 

Query OK, 0 rows affected (0.00 sec) 

mysql> select * from phonelist; 

+----------+-----------------+----------------+-----------------+----------------+-------------------+ 
| ParentID | ParentFirstName | ParentLastName | PlayerFirstName | PlayerLastName | GuardianHomePhone | 
+----------+-----------------+----------------+-----------------+----------------+-------------------+ 
|  8 | Gregory   | Peck   | Michael   | Peck   | 034871234   | 
|  9 | Laura   | Peck   | Michael   | Peck   | 034871234   | 
|  10 | Martha   | Petersen  | Matt   | Petersen  | 034724321   | 
|  10 | Martha   | Petersen  | Christopher  | Petersen  | 034724321   | 
|  11 | Chris   | Michaels  | Richard   | Michaels  | 034791212   | 
|  11 | Chris   | Michaels  | Shaun   | Michaels  | 034791212   | 
|  12 | Nadine   | Michaels  | Richard   | Michaels  | 034791212   | 
|  12 | Nadine   | Michaels  | Shaun   | Michaels  | 034791212   | 
|  13 | Barry   | Dackers  | Harry   | Dackers  | 034871996   | 
|  14 | Kevin   | Mitchell  | Daniel   | Mitchell  | 034742886   | 
|  15 | Rebecca   | Mitchell  | Daniel   | Mitchell  | 034742886   | 
+----------+-----------------+----------------+-----------------+----------------+-------------------+ 
11 rows in set (0.00 sec) 

mysql> 

la creación de este punto de vista fue un reto, pero la descripción a continuación es lo que yo estoy teniendo problemas para navegar por:

También necesito agregar el equipo de cada jugador con esta vista. Debido a que hacer coincidir el nombre del equipo requiere unir 4 mesas, tengo problemas para fusionar las cosas. Me las arreglé para crear una consulta independiente que coincide con los jugadores a los equipos a continuación:

mysql> select person.firstName, person.lastName, team.teamName 
    -> from person join player on person.personID = player.playerID 
    -> join teamAllocation on person.personID = teamAllocation.playerID 
    -> join team on teamAllocation.teamID = team.teamID; 

+-------------+----------+------------+ 
| firstName | lastName | teamName | 
+-------------+----------+------------+ 
| Michael  | Peck  | U10 Red | 
| Christopher | Petersen | U10 Red | 
| Richard  | Michaels | U11 Orange | 
| Shaun  | Michaels | U9 Yellow | 
| Matt  | Petersen | U11 Orange | 
| Harry  | Dackers | U9 Yellow | 
| Daniel  | Mitchell | U9 Yellow | 
+-------------+----------+------------+ 
7 rows in set (0.00 sec) 

mysql> 

El resultado estoy visualizando en mi cabeza es algo como esto:

+----------+-----------------+----------------+-----------------+----------------+----------------+-------------------+ 
| ParentID | ParentFirstName | ParentLastName | PlayerFirstName | TeamName  | PlayerLastName | GuardianHomePhone | 
+----------+-----------------+----------------+-----------------+----------------+----------------+-------------------+ 
|  8 | Gregory   | Peck   | Michael   | U10 Red  | Peck   | 034871234   | 
|  9 | Laura   | Peck   | Michael   | U10 Red  | Peck   | 034871234   | 
|  10 | Martha   | Petersen  | Matt   | U11 Orange  | Petersen  | 034724321   | 
|  10 | Martha   | Petersen  | Christopher  | U10 Red  | Petersen  | 034724321   | 
|  11 | Chris   | Michaels  | Richard   | U11 Orange  | Michaels  | 034791212   | 
|  11 | Chris   | Michaels  | Shaun   | U9 Yellow  | Michaels  | 034791212   | 
|  12 | Nadine   | Michaels  | Richard   | U11 Orange  | Michaels  | 034791212   | 
|  12 | Nadine   | Michaels  | Shaun   | U9 Yellow  | Michaels  | 034791212   | 
|  13 | Barry   | Dackers  | Harry   | U9 Yellow  | Dackers  | 034871996   | 
|  14 | Kevin   | Mitchell  | Daniel   | U9 Yellow  | Mitchell  | 034742886   | 
|  15 | Rebecca   | Mitchell  | Daniel   | U9 Yellow  | Mitchell  | 034742886   | 
+----------+-----------------+----------------+-----------------+----------------+----------------+-------------------+ 

Si alguien me puede ayudar en esto lo haría se muy agradecido Para aquellos de ustedes que quieran probar las consultas con los datos, he puesto los scripts de esquema (DDL) y de datos (DML) (en un solo "pegar") al http://pastebin.com/S4iJyJUh.

Además, si alguien piensa que hay una mejor manera de hacerlo, avíseme.

Answer 1

Ya casi está allí, solo necesita combinar las dos consultas.

CREATE VIEW phonelistWithTeams AS 
SELECT parent.parentID AS ParentID, 
    ParentPerson.firstName AS ParentFirstName, 
    ParentPerson.lastName AS ParentLastName, 
    ChildPerson.firstName AS PlayerFirstName, 
    ChildPerson.lastName AS PlayerLastName, 
    team.teamName AS TeamName, 
    GuardianHomePhone.homeNumber AS GuardianHomePhone 
FROM parent 
    JOIN player ON (parent.parentID IN (player.motherID, player.fatherID)) 
    JOIN person AS ParentPerson ON (ParentPerson.personID = parent.parentID) 
    JOIN person AS ChildPerson ON (ChildPerson.personID = player.playerID) 
    JOIN addressDetails AS GuardianHomePhone ON (GuardianHomePhone.personID = parent.parentID) 
    JOIN teamAllocation ON (ChildPerson.personID = teamAllocation.playerID) 
    JOIN team ON (teamAllocation.teamID = team.teamID); 

Correr SELECT * FROM phonelistWithTeams le dará

+----------+-----------------+----------------+-----------------+----------------+------------+-------------------+ 
| ParentID | ParentFirstName | ParentLastName | PlayerFirstName | PlayerLastName | TeamName | GuardianHomePhone | 
+----------+-----------------+----------------+-----------------+----------------+------------+-------------------+
