Calculé tu solId
fue para solitications
. Originalmente pensé que significaba sólido (como una roca). Entonces, esto se puede hacer a través de la composición.
Tenga en cuenta que hubo algunos errores tipográficos en el esquema proporcionado. Algunas comas faltantes, algunos nombres de índice engañados. Una tabla MyISAM cambió a INNODB. Así que hice algunos cambios de nombre. Además, alrededor de la mesa 5 faltaban mesas. Por lo tanto, no es como si su secuencia de comandos se ejecutara (para la tabla rfqs
).
Del mismo modo, el siguiente esquema fallará debido a que faltan las tablas proporcionadas, en algún lugar alrededor del 60 al 70 por ciento.

compTableX001
es como una mini jerarquía TwoParents-OneChild con el nombre ID
. Así que ID
es el nombre de la paternidad. Tiene dos padres (BaseRFQId
y SolId
) y un hijo (NSNId
). El nombre o identificador, como ID
, es el destino FK de baserfqssols
fila que soporta. Referenciado y Referencia , respectivamente.
Del mismo modo, compTableX002
parece resolver las condiciones ahora para la Pregunta 2.
