I have table with the following definition:
create table table1( account_no int4, start_date_tme datetime ....);
The table may contain null values for start_date_time.
When I run the following SQL query, it fails:
select * from table1where start_date_time::date >= '01/01/2000'::date and start_date_time::date <= '01/01/2001'::date;
I get error message 'Unable to convert null datetime to date.
It's fine if I run the same SQL query with added condition as follows:
select * from table1
> where account_no = 1and start_date_time::date >= '01/01/2000'::date and start_date_time::date <=
'01/01/2001'::date;
Is this a bug? Or there's an logical explaination for this?
