I would do it this way:
<CFQUERY NAME="USAM4" DATASOURCE="blah">
UPDATE mytable SET
switch = left(switch, 3) + '1' + right(switch , len(switch) -4)
WHERE po = 236107
</CFQUERY>
In other words drop the single quotes from everything except the number
you're swapping, otherwise, what you'll end up with is a string that
literally concatenates your functions into the string (e.g. switch will
equal "left(switch, 3)1right(switch , len(switch) -4)").
I'm not sure why it would give you null though -- it really should bomb.

hmmmmmmm, I think I have the syntax correct , here is what Ive tried:
<CFQUERY NAME="USAM4" DATASOURCE="blah">
UPDATE mytable SET
switch = 'left(switch, 3)' + '1' + 'right(switch , len(switch) -4)'
WHERE po = '236107'
</CFQUERY>
I also tried this which gives me the same results, <NULL>.
<CFQUERY NAME="USAM4" DATASOURCE="blah">
UPDATE mytable SET
switch = CAST( left( cast(switch AS varchar(11)) , 3) + '1' + right(
cast(switch AS varchar(11)) , len( cast(switch AS varchar(11)) ) -4) AS
Numeric)
WHERE po = '236107'
</CFQUERY>
DB: SQL7
CF: 4.01
Perhaps its ODBC driver related......wierdness

Actually I just tried it from CF on a test table, and it's working fine (i'm
using CF5 Beta 1, but I don't think that matters). Maybe there was a slight
difference in your syntax? Here's the cf query
<cfquery datasource="dubliners" name="qry" username="sbloom">
USE pubs
UPDATE tbl
SET col =left(col,3)
+ '0'
+ right(col, len(col) - 4)
</cfquery>
pubs is the database, tbl is the table, and col is the column. Zero can of
course be replaced with any digit.
Hope it works --- feel free to post a more complete version of your code if
it doesn't.
