Why not just loop the below query to generate more then 1 column:

<cfquery DATASOURCE="myDataSource">
ALTER TABLE myTable ADD COLUMN NewColumnName myColumnType
</cfquery>

WHERE...
myTable is the name of the table you're adding the column to.
NewColumnName is the name of the new column.
myColumnType is the type of field you're adding (TEXT, MEMO, CURRENCY,
ETC).

There are also rules governing more detailed aspects of column
 adding. EG: If I wanted to put a restriction of 50 characters on 
a new text field I was adding, I would use the following :

<cfquery DATASOURCE="myDataSource">
ALTER TABLE myTable ADD COLUMN NewColumnName TEXT(50)
</cfquery>

Similarily you can delete Columns by using :

<cfquery DATASOURCE="myDataSource">
ALTER TABLE myTable DROP COLUMN NewColumnName
</cfquery>

What was the error message you were getting?  IIRC, you can't use ali
ased
columns in your where clause, so you need to put your whole computati
on into
your where clause as well.  How's that for code reuse :)

ew
column


Was wondering if anyone knows how to add up 4 columns in a query, giv
e the
result a new column name, and then use that new column name in the WH
ERE
part of the query.

Situation is where some customers are 30, 60, 90 or 120 past due. So 
I'm
trying to add up the 30,60,90,120 column totals and save the result a
s a new
column called TOTALOUTSTANDING

Then we want to send emails to anyone where TOTALOUTSTANDING > 5   (w
here
the total outstanding is more than $5)

I tried this script, but the dang thing never worked:(

<CFQUERY NAME="pastduenotice" DATASOURCE="customers">
SELECT first_name, email_address, customer_number, total_due, (past_d
ue_30)
+ (past_due_60) + (past_due_90) + (past_due_120) AS totaloutstanding
FROM accountsreceivable
where totaloutstanding > 0
</CFQUERY>

Appreciate any enlightenment on this one:)
