Question

I am trying to insert some very long text into a string prop - it worked perfectly fine with LinqToSql, now I have switched over to NHibernate and want to save the same enti

I hit a similar problem but using a CustomType (derived from IUserType). It turns out to be easier to fix than without a custom type. All you need to do is define SqlTypes to explicitly return the longer string length type you want.

public SqlType[] SqlTypes
{
    get
    {
        // Explicitly specify the string max length 
        return new SqlType[] { SqlTypeFactory.GetString(Int32.MaxValue / 2) };
    }
}

This solved the problem for us quite nicely.
