Cuando hago esto:MySQL view devuelve más resultados con un AND?
select * from vw_active_employees where division IS NULL; --319 results
tiene sentido. Y, entonces hago esto ...
select * from vw_active_employees where division IS NULL AND udds IS NULL; -- over 1000 results
Whaaaaat ?? ¿¿Más resultados??
Entonces, tuve que ajustar la vista como una subselección para que me devolviera lo que esperaba. De esta manera:
select vw_active_employees.* from (select * from vw_active_employees) tmp where division IS NULL AND udds IS NULL; --317 results
¿Alguien puede explicar esto? Nunca tuve que hacer esto en MS SQLSERVER, así que esto es extraño para mí.
El SQL utilizada para crear esta imagen en realidad se une a una serie de otros puntos de vista juntos. No estoy completamente seguro de que es muy útil para ver, pero tú lo has querido :) Se trata básicamente de

favor nos muestran la vista (lo consulta usó para crear la vista vw_active_employees?) – cristian
añadido la vista crear declaraciones anteriores de las opiniones pertinentes. Parece que el 'udds es nulo' de alguna manera se filtra y afecta la vista subyacente sql, lo cual me parece incorrecto. Desde mi entendimiento de las vistas, deberían ser una caja negra con resultados establecidos, y los criterios que apliquen no deberían afectar las consultas subyacentes que crean el conjunto de datos de la vista. – bmherold
El manual dice que "IS" tiene mayor prioridad que "Y", pero ha intentado: 'donde (división IS NULL) AND (udds IS NULL);' –
