Using UDT's for passing rows to a PL/SQL procedure

Question

I'm trying to get a list of rows into a procedure...
With ODP 11 - I thought that I would simply need to create a UDT of an object (i.e. user_id, first_name, last_name) and - then type which is a collection of that object.
Then - using that object type collection as a parameter in my procedure - pass the numerous rows from .NET in.
I've found a examples with varray's, nested varrays etc... but - nothing straight forward with passing a collection of rows.
Does anyone know of any online examples that illustrate this?
Thanks for your help!

Hi,
A BLOB variable is just a pointer to binary data and you are passing a text string to your procedure which is why you have the error. So to write a blob into a table in a procedure you need something like this:
CREATE OR REPLACE PROCEDURE testone(
V_TEXT IN VARCHAR2
AS
V_SIGIMG BLOB;
BEGIN
insert into sin_image values(empty_blob())
returning blobcol into V_SIGIMG;
-- then copy the text as binary data, this does not convert the text to binary data
DBMS_LOB.WRITE(V_SIGIMG,1,LENGTH(V_TEXT),v_TEXT);
commit;
END;
/However, if you want to upload images into the table it is easier to use the Apex functionality to upload the image into the APEX_APPLICATION_FILES table then move the blob into your table using an INSERT or UPDATE.
