How to INSERT empty line into SEQUENTIAL table from PHP

[Stefan Schwarzer <stefan.schwarzer@xxxxxxxxxxxx>]

Hi,

rahter dump question, I guess....

But I have a table with a sequential index field, into which I would  
like to add from time to time another line (via webbrowser), which in  
turn, stays first empty, before it's being filled in later (via  
webbrowser).

Because the ID field is sequential and indexed, I can't use

	INSERT INTO table_xx (ID, field2, field3, field4) VALUES ('', '', '',  
'');

neither (skipping ID because it should be filled in automatically):

	INSERT INTO table_xx (field2, field3, field4) VALUES ('', '', '');

How am I supposed to do it?

Thanks for any hints,

Stef
