Hi I m trying to pass User Defined Type as parameter to stored
procedure define in Oracle.Its is working fine with Oracle 11 +
ADO.net.But facing problem in integrating with NHibernate.
Following are the IType implementation procedure ,User defined Type ,
Call from NHibernate and Exception coming.
public class EmployeeCustomTest: NHibernate.Type.IType
{
private static readonly SqlType[] sqlTypes = new SqlType[]
{new SqlType(DbType.Object)};
// private static readonly SqlType[] sqlTypes = new SqlType[]
{ new SqlType(DbType.Object) };
#region IType Members
public void NullSafeSet(IDbCommand cmd, object value, int
index, ISessionImplementor session)
{
if (value == null)
{
((IDataParameter)cmd.Parameters[index]).Value =
DBNull.Value;
((IDataParameter)cmd.Parameters[index + 1]).Value =
DBNull.Value;
}
else
{
var name = (EmployeeType)value;
((IDataParameter)cmd.Parameters[index]).Value = name;
//((IDataParameter)cmd.Parameters[index]).Value =
(object)name.EmployeeId ?? DBNull.Value;
//((IDataParameter)cmd.Parameters[index + 1]).Value =
(object)name.EmployeeName ?? DBNull.Value;
}
