Hi:
Has anyone encountered this before?
SELECT CAST ( (NULL*NULL) AS NUMERIC(2,0));
returns the following error message:
Cannot cast type '"char"' to '"numeric"'
But the following sql statements returns NULL:
select NULL:
select NULL * NULL;
select cast ( NULL as NUMERIC(2,0));
Thank you in advance,
ludwig.
