I have a table which a column of type char(1) and default value is null
My Hibernate Object has an attribute which is of type char
When I try to insert a record in the table.
I dont set the status to any value and do a session.save.
The status column is populated with a value and not its default value null.
Can u pls help?

char is a primitive type, like int. It can't be null: it can be the null character ('\0'), but not null.

You probably want to change the type of the field (in your java code) to Character. You shouldn't have to change your mapping or anything else: autoboxing will look after all of that.
