Re: date array

While down loading 8.1.3, I tried the following:

update pf_inspectionsBld set insdate[0] = current_date
update pf_inspectionsBld set insdate[1] = current_date
update pf_inspectionsBld set insdate[2] = current_date
update pf_inspectionsBld set insdate[3] = current_date
update pf_inspectionsBld set insdate[4] = current_date + 1
select * from pf_inspectionsBld
A-2 | 1793 |
[0:4]={04/24/2006,04/24/2006,04/24/2006,04/24/2006,04/25/2006}

yet if I try
update pr_inspectionsbld set inspdate[3] = null
then
select * from pf_inspectionsBld
A-2 | 1793 |
[0:4]={04/24/2006,04/24/2006,04/24/2006,04/24/2006,04/25/2006}

i.e. no error and no change

what am I missing??

thanks
