Hi,

I accidentally posted this query on NHibernate Users group! Apologies for that.

I have a java class, with a member called "nativeFlag", which is of type java.lang.Boolean. (which means that it's nullable). In the mapping file, I haven't explicitly mentioned any type for nativeFlag.

When my table is created, the "nativeFlag" field is stored as a "tinyint" column in my Sybase DB.

Now, when the value in nativeFlag is NULL, I want NULL to be inserted in my DB. However, always 0 gets inserted.

How do I insert NULL in the table, if "nativeFlag" is null?

Need help on this.

Thanks in advance :-)

You should probably define your own UserType. You could extend Hibernate's implementation for Boolean and provide support for a third value (null) in addition to true/false.
Check the wiki for examples.
