Difficulty adding products to products.dbf

You have to get the next available product id from the storekey.dbf, and then increment
that number so when other systems try to update the product table they don't reuses a
duplicate id.

> Hi,
>
> I am working on an application that ties together our product management
> software with our site. I've written the following code to add a new
> product to products.dbf.
>
> When the script is run we receive the following error:
>
> miva/AddNewProduct.mv: Line 42: MvPACK: Runtime Error: Index
> 'prd_id.mvx00000001' was created with the UNIQUE flag and the key '1212'
> already exists in the index file miva/AddNewProduct.mv: Line 43: MvCLOSE:
> Runtime Error: Database 'products' is not open
>
> Where 1212 is the last id listed in prd_id.mvx.
>
> However the product is added correctly with unique, increasing id (although
> we have to pack the table through the admin to see them).
>
> HOWEVER, when another product is then added through the admin, it's given a
> duplicate id (!!!) and the following error .
>
> lib/db.mv: Line 4425: MvADD: Runtime Error: Index
> 'Merchant2/00000001/prd_id.mvx' was created with the UNIQUE flag and the key
> '1212' already exists in the index file
>
> Even after packing, this product cannot be seen through the admin, and it
> has to be removed using a script.
>
> QUESTION 1: Why isn't the index being updated when I add the products?
> QUESTION 2: Why do I have to use the admin to pack the products file before
> I can see the new products in the admin when I've packed (or tried to) them
> in the script?

> Much thanks,
