Dependinng on the contents of the 'empty' columns (i guess you want to retrieve the content of the rows that have a value for a certain column), it would be either:
- column <> ''
- column <> 0
- column IS NOT NULL

ok thanks
edit:
the type of column is varchar, it seems to be yielding no results...but i know that some of them are empty.

the sql query i am running is:
[sql]
"SELECT journal_id, whocanview FROM " . TABLE_PREFIX . "journals WHERE whocanview IS NOT NULL"
[/sql]

Describe the table, look in phpMyAdmin, look in the scripts that created it.

under the column labeled "null" it says no for that field so i guess using IS NOT NULL will not work?

Correct, the column will then contain the default value.

try with: column <> ''
