In addition to Adam's answer, it depends on whether the function is native or user defined.  If the latter, there may be permissions to be granted.

What problem are you having anyhow?

I am doing simple math within a query of query.

Specifically:

<cfquery dbtype="query" name="qClubRecord">

SELECT

SUM(WIN) AS WINS,

SUM(LOSS) AS LOSSES,

SUM(TIE) AS TIES,

SUM(WIN)/(SUM(WIN) + SUM(LOSS) + SUM(TIE)) AS WIN_PERCENTAGE

FROM

qGetRecords

</cfquery>

This works.

My problem arises when displaying. I would like to show only 2 decimal places.

Now, I'm using <cfgrid> with format="html", so I can't use numberFormat.

I should be able to solve this problem within SQL. After a quick look I found the FORMAT() statement.

Works as advertised from the command line, but incorporating into <cfquery> fails (whether QoQ or not).

So I'm stuck.

<cfquery dbtype="query" name="qClubRecord">

SELECT

SUM(WIN) AS WINS,

SUM(LOSS) AS LOSSES,

SUM(TIE) AS TIES,

FORMAT(SUM(WIN)/(SUM(WIN) + SUM(LOSS) + SUM(TIE)),2) AS WIN_PERCENTAGE

FROM

qGetRecords

</cfquery>

Thank you both for answering.

Did you read the docs I pointed you to regarding QoQ, and does it indicate it supports format()?

It depends on what you mean.

<cfquery> doesn't support any SQL statements.  All <cfquery> does is pass the string within it (along with any params) to the DB driver, which passes it on to the DB.  <cfquery> knows nothing about SQL.

The only situation in which "<cfquery>" might be expected to know something about SQL is in a query-of-query situation, although even then <cfquery> just passes the SQL to the IMQ (I am guessing that stands for In-Memory Query?)... um... driver / engine / system / whatever-one-might-call-it.

The SQL that IMQ supports is very minimalist, and is detailed - in full - in the docs:

http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec0e4fd-7ff0.html

But for normal queries, CF just passes the SQL to your database, and that's where the SQL is executed.  The SQL is just a string, as far as CF is concerned.
