Bug reference:      4956

Operating system:   Windows Vista Ultimate
Description:        Array Construct array() returning blank result

I simply wanted to accumulate result of a subquery in to an array, so I did
select array(select userid from user where <some condition>);

Only when the condition gets evaluated to true with at least 2 columns with
varying values the array gets constructed, in all other cases what we get is
a complete blank output. the label of the result is as usual as ?column? but
there is absolutely nothing in the cell below the label.

I am sorry if I am repeating something already known to mankind :-) but
after a lot search I could not get anything on it on the net.

Thanks in advance.

Best Wishes.
