[dba-SQLServer] Diving off the deep end

>You can strip, concatenate, and update all in one query

Yea, I suppose. 

I wanted to clean up the fields themselves, and given how little I really
know I thought it best to just do the data cleanup in one step, then build a
new column and do the append in a second step.  I could be here all day
trying to get anything more complex that this done "all in one step".

Besides, I really need to take the time to learn the pieces.

Thanks to everyone who has helped out this morning.

IN the airline reservation system, in one query I pivoted the 200 incoming
comma delimited flights into a table using a UDF, left joined with the
existing flight cache, parsed the flight data, calculated the number of legs
in the flight and inserted the result into a table variable. 

In SQL Server it's generally better to do as much as possible in as few
set-based operations as possible.

I'm getting there.  I now have a query running stripping the leading zeros
from three fields that I will then need to append together to get a single
address field.

So much of this stuff is easy enough if you do it all the time.  My problem
is that I am just spread too thin.
