View 5 RepliesI am working on a database with about twenty tables. In one of the tables "Customers" their is a column with
a primary key. Call it "CustomerNumber".
The problem is that we log customers from multiple vendors and so we might have the same customer number, but from different vendors. So really this would be a perfect situation where we could set up the primary key to be a composite key consisting of the Vendor and CustomerNumber combination.
The integrity of the database is not very well maintained because the Primary Key CustomerId is never used as a secondary key in any of the other tables.
So here is my question. Instead of making a primary composite key, can I just drop the primary key all together?
This is one of those questions I really hate to ask, because typically I would never lean tword this drastic of a measure to solve a problem. Because of other situations I can't discuss this might be the best alternative. So would it be okay to drop the primary key constraint all together?

I'm trying to emulate an Ajax CalendarExtender to match an existing ASP:Calendar using CSS. Here are the properties (not in CSS but on the actual .aspx) of the regular ASP:Calendar:
<asp:Calendar ID="Calendar1"

BackColor="#99FFCC"
style="text-align: center"

<WeekendDayStyle
BackColor="#14CBCB" />
<TitleStyle Font-Bold="True" />
</asp:Calendar>
So far setting several CSS settings, nothing appears but a white calendar with black numbers.

I currently have a table that has a few hidden text boxes... The text boxes become visible when certain actions are performed.
The table though changes size according to when the textboxes are visible or now. Ex. When the textboxes are visible the table grows, and vice versa.
I would like to keep the table size at its max size ( size when the text boxes are visible) even when they are not.
