It's my choice of words, I expect. By "compound" I just mean more than one condition in the WHERE clause. Something like:

SELECT * FROM tastrade!products;
 WHERE (  VAL(Products.supplier_id) = ( ?ln_SupplierID );
   OR  VAL(Products.product_id) = ( ?ln_ProductID ) );
   OR  Products.product_name LIKE ( "%"+?lcProduct_name+"%" )

>SELECT * FROM customers WHERE

> custid gives all records OR custid gives one record

I still would use two different views for this case. lv_customers (all, or all active, for example), and lv_customer (parameterized view).
