Here we go. I am accessing the database through an ODBC connection
using the most recent version from Christian's site..

The table schema :

CREATE TABLE invoice_items (
item_id INTEGER PRIMARY KEY,    
invoice_id int4,
product_id int4,
product_name text   ,
sku text   ,
description text   ,
quantity text,
price int4,
cost int4,
taxable bool,
format_price text,
format_total_price text,
taxable2 boolean)

The query :

INSERT INTO invoice_items
(item_id,invoice_id,product_id,product_name,sku,description,quantity,price,cost,taxable,taxable2,format_price,format_total_price)
VALUES (NULL,899,1001975,'HD0001 - ASH - YL','','HOUSE
DIVIDED',1,800,450,'f','f','$8.00','$8.00')

The error :

PRIMARY KEY must be unique (19)

I can't post the database itself because it contains some sensitive
information (as you might have guessed, it's a database of billing
information).

The INSERT query for the invoice_items table has "NULL" hard coded in
for item_id, so I know it's not accidentally being set to an existing
value.


Can you select the max and min item_id values form the database and report them back here.

Can you then change your code to insert a new dummy record with an item_id that is set to one greater than the maximum value, rather than your hard coded NULL value. I just want to see if you can insert a properly formed record into your database at all. You should then delete that record so it doesn't cause a problem in your database later.
