No. a switch requires 'testing' the condition, and for every row.
The CSS way is much more efficient (and preferred for best practices) as
it's more flexible. You can change the CSS file easily without changing any
PHP code. But the speed will be the biggest improvement.

Remember that if you dont use an index on a colum and you search by that

Why would you want to do this? As data moves around within the table the
updates will be in error. Wouldn't it be easier to assign a unique key to each
row, search for the key or unique set of information and update the resulting
row?

This one has me puzzled. All I need to do is create a table of dates, one
date per row, from a starting to ending date.
So if the date range is '2001-01-15' to '2003-04-01' then it would generate
approx 800 rows with dates between these 2 ranges. I can't seem to figure
out how to do it without
A good point to make here is that averages are generally a poor

handle the peaks as well as the average. I know this, fought a number

Mark, can you provide a sample of a query you're currently using to
retrieve data from this table / joining on this table?
Also, how big is this table? It may not be worth your time to change
things around as this is a very simple structure and should remain
speedy even if it grows pretty large.
Neil, in theory, this should work fine, given sufficient bandwidth
between the two sites.
In practice, if it is a high traffic site generating a large number of
connections, or a high traffic site pulling large pieces of data

The only way to force a numeric zero instead of a NULL is to alter the table. Don't allow NULL's in the field and set a default
value of 0. However, you then lose the ability to determine is a value was actually entered or if 0 was entered. Don't know if that
matter to you.
Otherwise, you can u
