I'm not sure what you problem is but you need to look at your where clause. Using the SUBSTR function is going to slow your statement to a crawl. Remove the SUBSTR and the query should run fine and much faster. Also change the EMPTY(Articlesend.d_sent) = .T. to Articlesend.d_sent={}. Of course you should have an index on c_product_id and d_sent.

In your query with multiple records does/can an c_orderid show more than once. If so, you need to select an additional update key like the c_product_id field.

This seems to work fine when I am only working with one record that exists in the articlesend table but when I have multiple record I get update conflict error 1585. The situation is this in the articlesend table I can multiple records which I want to update put am only pulling out info from the customer table for label creation. The view is table buffered. Any ideas on what I am doing wrong here.
