MySQL, handling 0000-00-00 date

Hi, is there a way how to handle '0000-00-00' date in Zeos? I can not access is as string (empty '' string is shown). E convert error is raised when trying to save value. I understand that it is not proper date, but this allows for storing uncomplete dates 1920-10-00, 0000-05-18, etc. Thanks for help.

[SOLVED] Query, keep selected record after refresh

Is there a way to force Query to keep selected record after refresh (based on primary key)?
Now it seems, that when any avalue is changed, first record is selected (I understand this must be the case when current record is deleted).
