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.dbrecord that client has access to.Thanks, Kenneth, for your suggestions. It works (of course ;-)for the access restriction. But it does not solve the secondproblem: when I search for the client I get a list of all hisproducts. In [founditems] I loop through the product-sku's ofthe client and find associated categories in products.db withlookups. But because WebCat has no string variables :-( I cannotskip double names within the loop and therefore can't get uniquevalues 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 allfound 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 valuesvia 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 aframe version and the category list is generated just once, whenthe 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 towrite it like this:[appendfile somefile]sometext[/appendfile](I use BBEdit 4.5)Peter__________________________________________Peter Ostry - po@ostry.com - www.ostry.comOstry & Partner - Ostry Internet SolutionsAuhofstrasse 29 A-1130 Vienna Austriafon ++43-1-8777454 fax ++43-1-8777454-21
