Problem: What does null really mean? Solution: /*******************************************************************************/ Note: The information in this article applies to all InterBase versions. /********************************************************************************/ Null means that the value is not known. It does not mean a blank space or the value 0. The meaning of null is frequently misunderstood by users to mean blank or zero. As a result, the statement: insert into mytable(charField) values ' '; will work on a column that has not null defined. Blank is a known value.
