Hi Tony,
I am struggling with the implementation of the virtual private database system as you discribed in Implementing Virtual Private Databases and I have problems with a list 2 pattern.
I also read your article Technical Keys - their Uses and Abuses and I followed your proposal to avoid technical keys when possible.
I created tables with up to six or seven columns as Primary key. I don't know if this is the best way but all the tables are related in a one to many relation. (Cascading)
I mention this because the first colomn of these tables is always the field rdcaccount_id which is used for account access or shared access.
You described how to deal with a list 1 pattern and this works fine in my application, I see all the occourences made by a special account.
But if I want to see an account occurence in a list 2 form, I only see the entries of the shared account.
I inserted the code in the _getData() function after the code for checking the primary key:
if ($this->checkPrimaryKey AND !$this->allow_empty_where) {
// check that full primary key (or candidate key) has been supplied
I also tried inserting the code at the end of the function - same result.
So please, can you tell me where to insert the code at the right place?
Best regards,
Juergen
