Is Global Collection Possible

Question

Hi ,
I am on on 11g R2 and have the following query.
I have defined 2 collections in my Package Specification as g_valid and g_invalid.
In my package body I am using my main driving procedure to pass records (again as other collection types) to various procedures for validation , updates to some tables etc. Based on validation in one of the procedures called from within my main procedure I upload the errored records and valid records into g_valid and g_invalid collections.
Ultimately, I want to use these two 'global' collections to write an output report.
<<main>>
step1  cursor to get records to process
step2  load into a collection 'invoices_tab' (associative array type)
step3 pass invoices_tab to validate_proc
step4 inside validate_proc based on validations populate either g_valid or g_invalid collection whose scope is Global as defined in spec.
..........some steps
step5  cursor to get 2nd set of records to process
step6  load into a collection 'invoices_tab'
step7 pass invoices_tab to validate_proc
step8 inside validate_proc based on validations populate either g_valid or g_invalid collection whose scope is Global as defined in spec.
--- report valid and invalid records.
     IF g_invalid.COUNT > 0 THEN
           log_message_routine();
     END IF ;However, it appears to display only the 2nd set of valid or invalid records. It overwrites the collection.
How can I just append records to collection and read them all once in the end ?
Thanks

ShankyAs you haven't provided any actual code we can only guess.
I'm guessing you are loading your collections using a bulk collect? This will overwrite the collection... that's just a fact.
You would only be able to append records into the collection if you looped through the cursor and used PL/SQL collection methods to append them in, but this is likely to slow down the process.
My first question is... why on Earth are you doing all this with collections? SQL is the primary language for processing data (including any validation you may need), to give you results directly. Loading the data into collections and passing them about procedures etc. just uses up expensive PGA memory and reduces performance.
