Sounds horrible but we need it. We have a partitioned view which combines ten tables. The tables have a composite primary key and based on one of the key's the data goes into the correct table via the view and vice versa for querying So the view is supposed to query only one of the tables based on one of the keys. Except, it doesnt do it because the key is comming in as a parameter and in stead queries all the tables. Sql Server documentation states it should do it, but it doesnt. SQL without parameters seems to work as expected. Does any one know if LLBL can be set to use paramters or not? If so where?
