Question

我有一个存储过程，除了用户类型作为参数。从Nhibernate调用它时，它抛出以下异常。

从Nhibernate致电


EmployeeType emp = new EmployeeType(243214,"Anupam");

IQuery final = eventhistorysession.CreateSQLQuery("call testCustom (:pLocation)");
final.SetParameter("pLocation", emp, NHibernateUtil.Custom(typeof(EmployeeTypeCustomType)));
int result = final.ExecuteUpdate();

异常堆栈跟踪

我的自定义类

我在oracle中的存储过程和用户定义类型


public class EmployeeTypeCustomType : ICompositeUserType
{
    public Type ReturnedClass { get { return typeof(EmployeeType); } }
    public new bool Equals( object x, object y ) {
        if ( object.ReferenceEquals(x,y) ) return true;
        if (x == null || y == null) return false;
        return x.Equals(y);
    }
    public object DeepCopy(object value) { return value; }
    public bool IsMutable { get { return false; } }

public object NullSafeGet(IDataReader dr, string[] names, NHibernate.Engine.ISessionImplementor session, object owner) {
    object obj0 = NHibernateUtil.Decimal.NullSafeGet(dr, names[0]);
    object obj1 = NHibernateUtil.String.NullSafeGet(dr, names[1]);
    if ( obj0==null || obj1==null ) return null;
    decimal value = (decimal) obj0;
    string currency = (string) obj1;
    return new EmployeeType(value, currency);
}

public void NullSafeSet(IDbCommand cmd, object obj, int index, NHibernate.Engine.ISessionImplementor session) {
    if (obj == null) {
        ((IDataParameter)cmd.Parameters[index]).Value = DBNull.Value;
        ((IDataParameter)cmd.Parameters[index+1]).Value = DBNull.Value;
    } else {
        EmployeeType amount = (EmployeeType)obj;
        ((IDataParameter)cmd.Parameters[index]).Value = amount.EmployeeId;
        ((IDataParameter)cmd.Parameters[index+1]).Value = amount.EmployeeName;
    }
}

public string[] PropertyNames {
    get { return new string[] { "EmployeeId", "EmployeeName" }; }
}
public NHibernate.Type.IType[] PropertyTypes {
    get { return new NHibernate.Type.IType[] {
        NHibernateUtil.Decimal, NHibernateUtil.String }; }
}
public object GetPropertyValue(object component, int property) {
    EmployeeType amount = (EmployeeType)component;
    if (property == 0)
        return amount.EmployeeId;
    else
        return amount.EmployeeName;
}
public void SetPropertyValue(object comp, int property, object value) { 
    throw new Exception("Immutable!");
}
public object Assemble(object cached,
            NHibernate.Engine.ISessionImplementor session, object owner) {
    return cached;
}
public object Disassemble(object value,

    return value;
