SELECT * FROM tb WHERE name IS NULL;
And I think it should have been on the SQL list, myself...

Hi,
How can I get the tuples one of whose attributes is NULL?
For example, First, create table tb(id int,name text); Then insert into tb values(1);
insert into tb values(2,'Rose'); I want to select the tuples whose attribute name= NULL,
How to write the sql ?
select columns from table where attribute is null;
This should have been on postgresql-general, not on hackers..
