I'm trying to replace blanks in a datetime field in an excel csvv that is inserted in a MySQL database. I've tried all values found at http://staraphd.blogspot.com/2009/09/import-null-values-into-mysql-via.html to no avail.

What am I missing?

I think Heidi inserts NULLs for values which have a "NULL" string in it. But only for the "Client parses file contents" method.

Maybe an option for what to replace to NULL would be a nice idea like this:

Are we talking about the LOAD DATA command (server parsing) or the client parsing method in the import dialog?

From a user's perspective I'd say this should be transparent.

So this feature should be possible in both technics. How this is implemented on the SQL level is a different topic of course.

I will look into it... I think it is possible with some of the "escape"-parameters... It's been a while since I was into that low level console stuff :)

Sorry to resurrect this topic. I just post a new topic saying that \N is not translated to NULL when exporting and importing CSV. Thanks!
