sql - tablas - ver fk de una tabla oracle
¿Cómo fusiono dos o más filas según su clave externa? (3)
Tengo tres tablas que son:
A(a1, a2, a3)
//This tbl (Table) can have multiple instances of a1, but cause of its dependence on b1,
//we have a unique record each time
B(b1, a1, b2)
//tbl C has a relationship with tbl B through b1. b1 can also have multiple instances, but
//sometimes a number of unique records in this table can tie to just one record in the B tbl.
C(c1, b1, c2, c3)
Ejemplo:
//Table B sample data
b1 a1 b2
1 25 paper
2 29 pencil
3 29 parker
//Table C sample data
c1 b1 c2 c3
1 1 w long
2 2 b long
3 2 g short
4 3 v fat
Explicación: Para el registro 2 en tbl B, los registros 2 y 3 en tbl C deben formar un registro único para él.
De todas las cosas hasta ahora, tbl A puede tener múltiples registros en tbl B que son distintos a tbl A. Tbl B también puede tener múltiples registros en tbl C, pero esos registros múltiples deben fusionarse en un solo registro (Donde sea que haya un duplicar la clave foránea en tbl C, luego debe producirse una fusión).
Espero haber hecho un buen trabajo al explicar mi problema. Necesito una consulta para hacer esto. ¿Alguien puede ayudar, por favor?
Suma # 1: En un esfuerzo por hacerlo más claro usaré la situación real que enfrento.
Todos los medicamentos se agrupan bajo una clasificación principal, una clasificación secundaria y un nombre genérico.
-Main Classification
-Sub Classification
-Generic Name
Cada nombre genérico puede tener más de una fortaleza: Ejemplo:
-TRIMETHOPRIM
Strengths: 100mg, 200mg
También hay ocasiones en las que puede tener un nombre genérico que es una combinación de dos medicamentos y estos dos medicamentos tienen sus puntos fuertes, que se relacionan con la fortaleza de este nombre genérico. También puedes tener múltiples. Ejemplo:
-SULFAMETHOXAZOLE & TRIMETHOPRIM
Strengths: 40mg & 8mg/mL, 400mg & 80mg, 800mg & 160mg
Entonces, para permitirme hacer un seguimiento de las fortalezas individuales del nombre genérico combinado, necesitaba otra tabla.
GenericTbl(Id, Name, ...)
GenericDetails(Id, GenericId, ...)
Strenghts(Id, GenericDetailsId, Strength, Unit, DosageForm, ...)
Espero que esto ayude.
Suma # 2 He cambiado los ids a enteros en lugar de guid (uniqueidentifier)
Pharmacy_GenericDrug
GenericDrugID GenericDrugName DrugSubClassificationID ControlStatusID
1 TRIMETHOPRIM 12 2
2 SULFAME & TRIMETHOPRIM 4 1
Pharmacy_GenericDrugDetails
GenericDrugDetailsID GenericDrugID
1 1
2 2
Pharmacy_Strengths
StrengthID GenericDrugDetailsID DosageStrength Unit
1 1 200 mg
2 2 80 mg
3 2 8 mg/L
For the first#1 GenericDrugID = 1: TRIMETHOPRIM | 12 | 200 | mg | 1
For the second#2 GenericDrugID = 2: SULFAME & TRIMETHOPRIM | 4 | 80 | mg | 8 | mg/L | 1
1 > GenericDrugName | DrugSubClassificationID | DosageSrength | Unit | ControlStatusID
2 > GenericDrugName | DrugSubClassificationID | DosageSrength | Unit | DosageSrength | Unit | ControlStatusID
Aquí hay otra solución que usa SQLXML:
SELECT
STUFF
(
(
SELECT '', '' + cast(id AS NVARCHAR(max)) + '': '' + video
FROM Video
ORDER BY Id
FOR XML PATH ('''')
),1,1,''''
)
CREATE TABLE [dbo].[Video](
[ID] [int] NOT NULL,
[Video] [varchar](50) NOT NULL,
[Views] [int] NOT NULL
)
Resultado: 1: Hulk, 2: Jack, 3: El Rey
Actualización: también acabo de encontrar esto en Data Management and Exchange.

OK, tomemos una puñalada y veamos si esto nos lleva a algún lado.
Tabla A: GenericTbl (Id, Nombre, ...)
Tabla B: GenericDetails (Id, GenericId, ...)
Tabla C: Fortalezas (Id, GenericDetailsId, Strength, Unit, DosageForm, ...)
Si cuando dices fusionar estás buscando un conjunto de resultados que reúna los resultados para las fortalezas de un solo genérico, podrías hacer algo similar a
SELECT
g.Id,
g.Name,
gd.Id,
s.Strength,
s.Unit,
s.OtherFields /*fill in the blanks*/
FROM
GenericTbl g
INNER JOIN GenericDetails gd
on g.Id=gd.GenericId
INNER JOIN Strengths s
ON gd.Id=s.GenericDetailsId
ORDER BY
g.Id, gd.Id, s.Id
y eso le daría un solo conjunto de resultados en el que se enumerarían todas las fortalezas diferentes para cada uno de los genéricos, agrupados sus tipos, con cada resultado en una fila.
Si lo que quiere es una sola fila por tipo con columnas para indicarle las opciones disponibles, debería ser factible con los cursores y las tablas temporales, o pivotes, creo que desde la memoria.
Si lo que realmente está buscando es que los registros se combinen al insertar en la base de datos para que solo tenga un único registro subyacente que contenga todos los datos, entonces puede hacerlo a través de activadores, pero no puedo ver por qué Querría hacerlo porque terminaría con un mapeo 1: 1 para B y C y también podría tenerlos como una sola tabla.
