Hi,

i need help for a cristal report with DATASETS and SQL.

I have a table with people and another with his anual readings. Both in a dataset.

Table PERSON:

NUMPERSON

NAME

Table READINGS

NUMPERSON

YEAR

NUMBOOKS

How i can list the name of person who didn't read any book in the year indicated with a report parameter?

Thanks
