Hemos desarrollado un Report en el que utilizamos la expresión:
   Select NVL(count(*),0) from TABLA

Sabemos que esta expresión es correcta pero nos sale el error ORA-00936: falta una expresión.

El Report está desarrollado en la version 6.0 de Developer y la BBDD es la 8.0.5

¿Nos podías ayudar a solucionarlo?

Gracias.

didn't understand what you wrote,
but you do not need an NVL if you want only to count,
even is the table empty you will get a 0 as result

also use
Select count(*) from TABLA

count(*) will never be NULL. So, no need to use NVL
