 This test cause a OCI-Invalid call exception on my box...  
 It works only if I replace DBNull.Value by a 
 System.data.OracleClient.OracleString(string.Empty);

+Here is a fix that works for me in OracleParameter function Bind().
+Basically, set indicator and bindSize to 0 and set the bindType to
+VARCHAR2.  It works for VARCAHR2, NUMBER, and DATE.
+
+OciDataType bindType = ociType;
+IntPtr bindValue = IntPtr.Zero;
+int bindSize = size;
+
+if (value == DBNull.Value) {
+	indicator = 0;
+	bindType = OciDataType.VarChar2;
+	bindSize = 0;
+}
+else {
+
+I would commit this, but I'm working in the same area trying to get
+DateTime to work.
+
+if (value == DBNull.Value) {
+	indicator = 0;
+	bindType = OciDataType.VarChar2;
+	bindSize = 0;
+}
+else {
+	if (oracleType == OracleType.DateTime) {
+	// FIXME: this only works 
+        // if NLS_DATE_FORMAT is set to 'DD-MMM-YY'
+	// which is the default date format for Oracle
+	string sDate = ((DateTime) value).ToString ("dd-MMM-yy").ToUpper ();
+					
+	bindType = OciDataType.VarChar2; 
+	bindValue = Marshal.StringToHGlobalAnsi (sDate);
+	bindSize = sDate.Length;
+}
+else {
+	bindType = OciDataType.VarChar2; // FIXME
+	bindValue = Marshal.StringToHGlobalAnsi (value.ToString ());
+	bindSize = value.ToString ().Length;
+}
