Would it be OK to use varchar(5) instead of char(5) as the first field of a
composite clustered index?
My gut tells me that varchar would be a bad idea, but I am not finding much
information on this topic on this when I Google it.
Currently the field is Char(4), and there is a need to increase it to hold 5
characters.
TIA

Basically I'd like to implement the composite design pattern with leaves that
are either of reference or value types, but even using generics I can't seem
to avoid boxing (using ArrayList or Object)
Is this even possible, or is the composite pattern doomed to use the
System.Object type forever?
I have tried using interfaces with generics, but I always stumble on the
Value property (when trying to return the value of a particular node)

Summary:
1. I want to define a column in anMS Access table to be lookups on other
tables.
2. The table that is the data source (e.g the "parent" table) has a
composite
primary key.
3. When the "child" table does the lookup, it should pass all the columns
necessary
to properly restrict the data returned to the litbso for he lookup.
4. How do I accomplish this in a lookup?

Hi All
There are 2 Tables:
Tables are : Tbl1 ( 1col1,1col2,1col3,1col4) and
Tbl2 ( 2col1,2col2,2col3)
In Tbl1 (1col1,1col2,1col3 ) are composite primary key.So column values in column 1col2 may repeat
Now Columns 1col2 of Tbl1 and 2col3 of Tbl2 are of same data type

My client manager likes concatenated/composite primary keys. I don't.
Can anyone forward any arguments pro or con?

I have created a fairly basic composite control consisting of a Label
and a TextBox. In the overridden Render function, I'm creating a
table with two rows and each row contains a cell (td). The Label and
the TextBox are each rendered in one of the cells. Everything renders
fine. The problem is that depending on the column the control
represents I may want the textbox to be a different visible size
during both design and runtime. I...

Hi All,
I am about to make some changes to a process we have. The new process
will have a new table who's job it is to store temporarily data such
as customer, clerkno,productno, storeno , amount, time.
On a new request from a front-end i will select against the primary
keys to ensure no other request for the same data has been made. This
is then sent to a backend system asynchronously if there is no match.
I will otherwise send a...
