nullColumnHack parameter in insert() of SQLiteDatabase

[aby]

Hi,
Does anyone know the second parameter nullColumnHack in insert() of
SQLiteDatabase?

Android developer's define as follows:

SQL doesn't allow inserting a completely empty row, so if
initialValues is empty this column will explicitly be assigned a NULL
value.

I still don't understand after reading the explanation. Can anyone
tell me the usage of this function?

Thanks

For the second parameter, you need to supply the name of some column in
your database that allows NULL values, if there is one.

If you supply such a column, then SQLite will be able to handle the
situation where you have an empty ContentValues you are trying to insert
into the database.

BTW, this is a better question for [android-beginners] or
[android-developers], since this pertains to the SDK more than the
Android source code.
