Ho estratto la parte dell'anno e del mese dalla data, quindi il raggruppamento avviene per ogni mese di un determinato anno.

NOTA Considera il totale annuale come il totale mensile...

Ok ho il tuo problema nelle tue query aggiornate. Entrambi i casi dell'istruzione If dovrebbero restituire lo stesso tipo di dati del risultato, quindi quando stai provando a riportare i valori della data su numerico, il tuo true case restituisce varchar campo del tipo di dati che è TOTAL e il campo else restituisce un numeric campo tipo in modo che ciò causi l'errore.
Per risolverlo è necessario rimuovere la dichiarazione del caso, quindi funzionerebbe correttamente secondo le tue necessità.

Quindi ora devi sopportare valori nulli nelle colonne della data. Spero che questo risponda ai tuoi dubbi.
Spero che questo aiuti......
