texte = (Kenneth Grome:) >1- Create a Products.db with ALL your products >... >2- Create a Clients.db >... >3- Create one record in the Clients.db for EACH Product.db record that client has access to. Thanks, Kenneth, for your suggestions. It works (of course ;-) for the access restriction. But it does not solve the second problem: when I search for the client I get a list of all his products. In [founditems] I loop through the product-sku's of the client and find associated categories in products.db with lookups. But because WebCat has no string variables :-( I cannot skip double names within the loop and therefore can't get unique values for a category list:search clients.db for username [founditems] lookup products.db for SKU, return CATEGORY [/founditems] [/search]This returns a list of all categories, but with dup names.--------------------I solved this finally with a temporary database. I write all found categories into a temporary database file:search clients.db for username writefile: temp.db appendfile temp.db: SKU CATEGORY [founditems] appendfile temp.db: lookup products.db for SKU, return CATEGORY [/founditems] [/search]And now I search the created temp.db and get my unique values via the CATEGORYsumm command:search temp.db with CATEGORYsumm=t [founditems] [CATEGORY]
[/founditems] [/search] [closedatabase temp.db]That's it! This method is fast enough for my application since it is a frame version and the category list is generated just once, when the clients logs in.--------------------BTW - I discovered some strange behavior: [appendfile somefile]sometext[/appendfile] does not put a carriage return at the end of the line, I have to write it like this: [appendfile somefile]sometext [/appendfile] (I use BBEdit 4.5)Peter__________________________________________ Peter Ostry - po@ostry.com - www.ostry.com Ostry & Partner - Ostry Internet Solutions Auhofstrasse 29 A-1130 Vienna Austria fon ++43-1-8777454 fax ++43-1-8777454-21
