I have the following line declared in my Firebird database metadata:
DATE_ENTERED TIMESTAMP NOT NULL,

However, this is causing a problem with my code - it is refusing to post a
new record because it says this field is null. It's not however, in my code
the following line sets the value:

dstBookDATE_ENTERED.Value := DateEntered;

DateEntered is a variable of type TDateTime.

So where is the problem?
Thanks,
Stephen
