``Binding and Defining''
Binding RETURNING...INTO variables
As mentioned in the previous section, an OCI application implements the placeholders in the RETURNING clause as
pure OUT bind variables. An application must adhere to the following rules when working with these bind variables:
1.Bind RETURNING clause placeholders in OCI_DATA_AT_EXEC mode using OCIBindByName() or
OCIBindByPos(), followed by a call to OCIBindDynamic() for each placeholder.
Note: The OCI only supports the callback mechanism for RETURNING clause binds. The polling mechanism is
not supported.
2.When binding RETURNING clause placeholders, you must supply a valid out bind function as the ocbfp
parameter of the OCIBindDynamic() call. This function must provide storage to hold the returned data.
3.The icbfp parameter of OCIBindDynamic() call should provide a "dummy" function which returns NULL values
when called.
4.The piecep parameter of OCIBindDynamic() must be set to OCI_ONE_PIECE.
5.No duplicate binds are allowed in a DML statement with a RETURNING clause (i.e., no duplication between bind
variables in the DML section and the RETURNING section of the statement).
When a callback function is called, the OCI_ATTR_ROWS_RETURNED attribute of the bind handle tells the
application the number of rows being returned in that particular iteration. Thus, when the callback is called the first
time in a particular iteration (i.e., index=0), the user can allocate space for all the rows which will be returned for that
bind variable. When the callback is called subsequently (with index>0) within the same iteration, the user can merely
increment the buffer pointer to the correct memory within the allocated space to retrieve the data.
Every bind handle has a OCI_ATTR_MAXDATA_SIZE attribute. This attribute specifies the number of bytes to be
allocated on the server to accommodate the client-side bind data after any necessary character set conversions.
Note: Character set conversions performed when data is sent to the server may result in the data expanding or
contracting, so its size on the client may not be the same as its size on the server.
An application will typically set OCI_ATTR_MAXDATA_SIZE to the maximum size of the column or the size of the
PL/SQL variable, depending on how it is used. Oracle issues an error if OCI_ATTR_MAXDATA_SIZE is not a large
enough value to accommodate the data after conversion, and the operation will fail.

the little bastard above took me ages to find out
seems Oracle does not like people to know that it can do this
the concept is simple really
1. pin the object
2. bind with dty = SQLT_NTY
3. OCIDefineObject using the TDO
4. one gets the null indicator of the objcet with OCIObjectGetInd
The the obj_ind is for the entier object not the properties so you call it once it
gets all of the indicators for the objects so you pass it into OCIObjectGetAttr and that
function will set attr_null_status as in the get below.
5. interate over the atributes of the object
The thing to remember is that OCI and C have no way of representing a DB NULLs so we use the OCIInd find out
if the object or any of its properties are NULL, This is one little line in a 20 chapter book and even then
id only shows you examples with the C struct built in and only a single record. Nowhere does it say you can do it this way.
