Query of Queries on 2 datasources

I'm trying to do a query of queries on 2 different
datasources. I run a gaming site and have a 2 programs that are
used for tracking. One is written in php, by someone else, that
tracks members point status. The other, I wrote in CF, allows
members to set up treasure priorities. Both are stand alone on my
server. What I am trying to do is set it up so the program I wrote
in CF will display the # of points each member has. I know how to
query the separate tables but how can I combine them? Also, how can
I set it up so that it only shows the members that match. i.e. I
want to make sure that if John Smith has 100 points, the query will
show John Smith's 100 points on my table. Here is what the query
looks like as I have done it. As you can see, I'm confused about
the FROM and WHERE statements. I played with it last night and
couldn't get it to work. Thanks.

This leads me to a new question.
How can I output my query in my current table without
rewriting everything?
My original query is for the table and if I use the above
code with #combinedNames.member_earned# the table is 1 number. Like
this:
Preview
It's the 2nd column. Now, If I break the cfoutput and put in
a new cfoutput with the combined queries, it totally jacks up the
table all over the page. Hope that makes sense.

Can't find answer to Query Of Queries runtime error

Not only I browsed this forum but also googled this problem but unfortunnately I have no luck in finding the answer.
All I did was writing this simple query:
<cfquery name="test" dbtype="query">
select SSN,BirthDate from myquery where SSN <> '' OR BirthDate <> ''
</cfquery>
and I got this error:
Query Of Queries runtime error.
Comparison exception while executing <>.
Unsupported Type Comparison Exception: The <> operator does not support comparison between the following types:
Left hand side expression type = "DOUBLE".
Right hand side expression type = "STRING".
I tried the following and did not work either, still got the same error.
<cfquery name="test" dbtype="query">
select SSN,BirthDate from myquery
where SSN <> <cfqueryparam cfsqltype="CF_SQL_VARCHAR" value=""/>
OR BirthDate <> <cfqueryparam cfsqltype="CF_SQL_VARCHAR" value=""/></cfquery>
Has someone ever encountered the same problem and know how to solve it?

HELP ! ! ! Going into testing soon. I need this to work to get correct report results ! ! ! !
My issue seems similar to the one under discussion and the reply from lawhite01 caught my eye. Can you roll my issue into this discussion?
This is a 2 parter. The second part is the QoQ part, but the 1st part has a line in the query that is similar to the QoQ one and it uses the same data. Part 1 also throws an error.
PART # 1.
I'm trying to use a query table created through QueryNew and then query it.
I need multiple columns in the query table I create:
<cfscript>
        tot_AllCurrentDraftListing = QueryNew("AnnounceNum, JP_PDLoc, JP_JS_Title, JP_JS, JP_KW_1, JP_JobTitle, JP_Open, JP_Close, JP_CloseType, JP_CloseName, JP_PosNeed, JP_DirectHire, JP_Desc, JP_Draft, JP_Archived, JP_State, JP_AreaName, JP_AreaID, JP_AreaAlias, JP_Fac_SU, JP_Fac_Facility, JP_FAC_ID, JP_Grade1, JP_sal_low1, JP_sal_high1, JP_Grade2, JP_sal_low2, JP_sal_high2, JP_Grade3, JP_sal_low3, JP_sal_high3, JP_Grade4, JP_sal_low4, JP_sal_high4, JP_Grade5, JP_sal_low5, JP_sal_high5, JP_Posted, JP_TypeHire, JP_HRemail");
    </cfscript>
Then I populate all the cells of the query table.
Then I set up to use the created query table.
I do this first:
    <cfquery name="qAltPostID" datasource="#at_datasource#">
         SELECT AltPoster, fk_Job_AnnounceNum
         from JOB_JPContacts
         Where AltJPContactType = 'AltPosterID'
         and AltPoster = '#session.IHSUID#'
         </cfquery>
Then, in my first query using the created query, I expect to need to choose from multiple values, so I'm using this line in the query (this is NOT a QoQ query):
          and AnnounceNum IN (<cfqueryparam cfsqltype="CF_SQL_varchar" value="#ValueList(qAltPostID.fk_Job_AnnounceNum)#">)
I've also tried:
               and AnnounceNum IN (#ValueList(qAltPostID.fk_Job_AnnounceNum)#)
and:
             and JOB_AnnounceNum IN
                SELECT fk_Job_AnnounceNum
                from JOB_JPContacts
                Where AltJPContactType = 'AltPosterID'
                and AltPoster = '#session.IHSUID#'
ERROR is: one record should return. I get 0.
PART # 2: Here's the QoQ part.
I get the error:
Query Of Queries runtime error.
Comparison exception while executing IN.
Unsupported Type Comparison Exception: The IN operator does not support comparison between the following types:
Left hand side expression type = "LONG".
Right hand side expression type = "STRING".
A tutorial I found gave an example using only one column for this part of the fix:
     tot_AllCurrentDraftListing = QueryNew("AnnounceNum", "CF_SQL_VARCHAR")
How would I set up the query with the datatype when I'm using multiple columns:
<cfscript>
        tot_AllCurrentDraftListing = QueryNew("AnnounceNum, JP_PDLoc, JP_JS_Title, JP_JS, JP_KW_1, JP_JobTitle, JP_Open, JP_Close, JP_CloseType, JP_CloseName, JP_PosNeed, JP_DirectHire, JP_Desc, JP_Draft, JP_Archived, JP_State, JP_AreaName, JP_AreaID, JP_AreaAlias, JP_Fac_SU, JP_Fac_Facility, JP_FAC_ID, JP_Grade1, JP_sal_low1, JP_sal_high1, JP_Grade2, JP_sal_low2, JP_sal_high2, JP_Grade3, JP_sal_low3, JP_sal_high3, JP_Grade4, JP_sal_low4, JP_sal_high4, JP_Grade5, JP_sal_low5, JP_sal_high5, JP_Posted, JP_TypeHire, JP_HRemail");
    </cfscript>
I used this code after all the cells contained values and before running my QoQ query:
        <cfloop index="intID" from="1" to="#tot_AllCurrentDraftListing.recordcount#" step="1">
            <cfset tot_AllCurrentDraftListing["AnnounceNum"] [intID] = JavaCast("string", intID) />
        </cfloop>
          Is that correct?
Thanks.
Whoever can help me with this should be awarded extra points ! ! ! !

I have tried to achieve this result in many ways to no avail. If I try to combine PRODUCTS ORDERED with ORDERS I get an erroneous count. I finally resigned myself to getting all the info I needed with separate queries and then trying to combine them with a query of queries. This worked fine until the last query of queries which timed out with no results. I am a newbie and would appreciate any constructive help with this. I am including my queries below as well;
<cfquery name="qGetOrders" datasource="manna_premier">
SELECT Count(Orders.ID) AS CountOfID,
       Orders.UserID AS Orders_UserID,
    Users.UserID AS Users_UserID,
    Users.TMName
FROM Users INNER JOIN Orders ON Users.[UserID] = Orders.[UserID]
GROUP BY Orders.UserID, Users.UserID, Users.TMName;
</cfquery>
<cfquery name="qGetSalesCalls" datasource="manna_premier">
SELECT Count(Sales_Calls.ID) AS CountOfID,
       Users.UserID AS Users_UserID,
    Users.TMName,
    Sales_Calls.UserID AS Sales_Calls_UserID
FROM Users INNER JOIN Sales_Calls ON Users.[UserID] = Sales_Calls.[UserID]
GROUP BY Sales_Calls.UserID, Users.UserID, Users.TMName;
</cfquery>
<cfquery name="qGetProducts" datasource="manna_premier">
SELECT Count(ProductOrders.OrderID) AS CountOfOrderID,
       Sum(ProductOrders.Quantity) AS SumOfQuantity,
    Sum(ProductOrders.NewExisting) AS SumOfNewExisting,
    ProductOrders.UserID

</cfquery>
<cfquery name="qqCombOrd_ProdtoSales" dbtype="query">

</cfquery>
PLEASE HELP!!! I'm about to go scouting for bridges to leap from!

You might be able to simplify that query by getting rid of the subqueries. Something like this
SELECT TerritoryManager
, count(sc.userid) totalcalls
, sum(po.quantity) total
, sum(newexisting) totalnew
, count(o.userid) totalorders
from users u join salescalls sc on u.userid = sc.userid
join orders o on u.userid = o.userid
join productorders po on u.userid = po.userid
where userzone = 'CENTRAL'

Query Of Queries syntax error.

Hi all,
I have the following query:
<cfquery name="agent" datasource="datasourcename">
SELECT * FROM quotes where status = 'Pending'
<cfif isDefined("form.agent")>
AND agent = '#FORM.agent#'
</cfif>
</cfquery>
Then, I have the following query of that query
<cfquery name="totalvalue" dbtype="query">
SELECT SUM(value) as total FROM agent
</cfquery>
however I get the following error:
Query Of Queries syntax error.
Encountered "SUM ( value. Incorrect Select List,
on line 20 which is:
<cfquery name="totalvalue" dbtype="query">
now i'm sure this is identical to what ive used before but
getting the error. the totals query works fine when querying the
database direct, only got this error when I changed it to query the
master query.
i appreciate any help in advance, as no matter how much i
stare at it I can't see whats wrong!

I believe that
value is a reserved word that is probably causing your
current error. I would rename this column, or alias it in your
original query. Also, I would add WHERE value IS NOT NULL to your
Q-of-Q to cover your NULLs.

Bug in CF11 regarding Query of queries syntax?

So I have decided to try CF11 because of an official outstanding CF10 bug.
Once I installed CF11, I get an error when running code like this:
<cfquery name="LOCAL.stat_questions" datasource="#APPLICATION.dsn#">
     SELECT     survey_questionID
     FROM     tbl_survey_questions
</cfquery>
<cfset LOCAL.this_statID = 1>
<cfquery name="LOCAL.subset" dbtype="query">
     SELECT     survey_questionID
     FROM          [LOCAL].stat_questions
     WHERE     survey_questionID = <cfqueryparam cfsqltype="cf_sql_numeric" value="#LOCAL.this_statID#">
</cfquery>
The error I receive is: "Query Of Queries syntax error.
Encountered ";. "
If I remove the semi-colon... No error! Is this a bug, or was the semi-colon always bad, but just ignored?
Thanks

I just always put it in out of habit from typing out actual MySQL queries (non QoQ). Never was a problem and I always did it. Now running CF11... it requires fixing. Thought it was strange.
I actually didn't even notice that the semi-colons weren't required in QoQ until I ran into this CF11 bug. I also notice the semi-colon isn't necessary for a MySQL query either in cfquery! Seems weird that it accepts them, but isn't required. Just ignores them?

Is Query of Queries faster than multiple WHERE criteria?

If I need a recordset based on two table column fields (let's say firstName and lastName), is it better to run one query with a WHERE firstName = x AND lastName = y, or is it better to query of queries and find all records with a specified firstName, and then query that query to filter only records with a specified last name? Which is the better/faster method?
<cfquery name="somequery" datasource="someds">
SELECT *
FROM sometable
WHERE firstName = 'John' AND lastName = 'Smith'
</cfquery>
or....
<cfquery name="somequery" datasource="someds">
SELECT *
FROM sometable
WHERE firstName = 'John'
</cfquery>
<cfquery name="somequery2" dbtype="query">
SELECT *
FROM somequery
WHERE lastName = 'Smith'
</cfquery>

As a rule of thumb, make the database server do all the work... i.e. locally. If what you are interested is "first name = x and last name = y," then those are the only records that you want to be "sent over the little wire" to you. "The little wire" is always the bottleneck.

Query of Queries Error

I am using the same datasource to create a query of queries
but one of my queries is not being recognized. The code and error
message are as follows:

You don't use the datasource property with a query of query

tag. When you do query of query you are dealing with record
sets in
memory. Drop the 'datasource' parameter in the third
<cfquery...> tag.

Problem using DECODE() function with a Query of Queries

I
posted
on my blog about an issue I was having trying to use the PL/SQL
DECODE() function with a Coldfusion Query of Queries. This function
works fine when you query a database for information. However, when
you query another query, it seems that CF doesn't recognize it. I
got errors stating that it found a left parenthesis where it
expected a FROM key word. Here is a simplified version of what I am
trying to do:
quote:

<cfscript>
qOriginal = queryNew("Name,Email,CountryCode",
"VarChar,VarChar,VarChar");
newRow = queryAddRow(qOriginal, 5);
querySetCell(qOriginal, "Name", "Joe", 1);
querySetCell(qOriginal, "Email", "[email protected]", 1);
querySetCell(qOriginal, "CountryCode", "AMER", 1);
querySetCell(qOriginal, "Name", "Sally", 2);
querySetCell(qOriginal, "Email", "[email protected]", 2);
querySetCell(qOriginal, "CountryCode", "AMER", 2);
querySetCell(qOriginal, "Name", "Bob", 3);
querySetCell(qOriginal, "Email", "[email protected]", 3);
querySetCell(qOriginal, "CountryCode", "ASIA", 3);
querySetCell(qOriginal, "Name", "Mary", 4);
querySetCell(qOriginal, "Email", "[email protected]", 4);
querySetCell(qOriginal, "CountryCode", "EURO", 4);
querySetCell(qOriginal, "Name", "John", 5);
querySetCell(qOriginal, "Email", "[email protected]", 5);
querySetCell(qOriginal, "CountryCode", "EURO", 5);
</cfscript>
<cfquery name="qCountries" dbtype="query">
SELECT DISTINCT(CountryCode) AS CountryCode,
DECODE(states, "AMER", "North America & Canada",
"EURO", "Europe & Africa", "ASIA", "Japan &
Asia","") CountryName
FROM qOriginal
ORDER BY CountryCode
</cfquery>
<cfdump var="#qCountries#">

So running this returned the following error:
Query Of Queries syntax error.
Encountered "(. Incorrect Select Statement, Expecting a
'FROM', but encountered '(' instead, A select statement should have
a 'FROM' construct.
Does anybody know why this doesn't work? Is it just not
supported? Please note that I have also tried to use the CASE()
function instead of DECODE() and that resulted in basically the
same error. For now I an looping over my distinct query with a
switch statement and manually loading a new query with the data how
I want it. But it would be a lot cleaner and less code to have the
DECODE() to work. Thx!

DECODE() is an Oracle function, not generic SQL. Q-of-Q is a
very limited subset of SQL and lacks many functions and clauses
available in standard SQL, especially what you may be used to using
in your particular RDBMS.

Query of queries problem or bug

Hello Everyone,
I have used cfdirectory to get a list of files. As the result
I receive query with the files.
Then I want to search it using query of queries. I' ve found
a problem and I wonder if it is a bug of Coldfusion or perhaps
wrong usage of QoQ. The thing is that the files that I have are
using '_' and then are followed by number of week. It seems that
searching something like this '%_6' returns results *_*6. See
attached code.
Thanks for all answers in advance.

> I think you'll find "_" is a single-char wildcard when
used with the LIKE
> operator.
Found out how to escape it:
WHERE Name LIKE '%[_]6%'
I'm glad you brought this up... I didn't know about this
until I looked @
your issue. That's my new thing learned for the day: I can go
to the pub
now ;-)

Query of Queries problem

Over the past several weeks we've been experiencing periodic
hangs of the ColdFusion service. We finally invested in SeeFusion
and found the problem, but aren't sure how to fix it
The code that hangs is a query of queries block. Basically we
are getting a result set from verity (~1000 rows), then getting a
result set from SQL server (~3000 rows), and joining the two with
the query of query statement. Everything will run fine for a few
hours, then that block of code will bog down. When I dumped the
threads during the error, everything gets hung like so:

I believe this means CF is trying to "guesstimate" the java
type of each column in the result set. We tried to work around that
by CASTing each column as a varchar, but we still have the same
issue.
If anyone has an idea what the problem could be, we'd really
appreciate any help. Also, if anyone can suggest a way to merge the
two result sets without using SQL, that would be great too. I've
already tried nested loops to manually build the final result set,
but that was taking up to 5 seconds to run.
Environment:
CFMX 7.0.2
Win2K
SQL Server 2K

Right. And what do you need THOUSANDS of matches for, in one
hit, here?
And what do you need ALL those columns for, when dealing with
all these
thousands of rows. You've not really answered my question as
to "what's
the end result here?" What are you trying to achieve? I don't
mean what
you're doing to aggregate the data, but simply *why*? What is
the
requirement you have here to be engaging in this enterprise
in the first
place? Search screen? Stock control report? What?
Is there any way of optimising how much processing you're
doing?
If - say - you're doing a search results screen, you probably
don't need
1000s of results: you probably need 20. So just ask the DB
for 20: WHERE
id IN (#list of 20 IDs from Verity search results#)
If the user goes "NEXT >>", then grab the next 20
(cache the Verity query
somehow, rather than re-query it).
Obviously there's some heavy-lifting processing that might
need to process
the whole lot. Can this not be done in a sliding window of
results? Or
could you not pass the list of IDs from the Verity resultset
into the DB
somehow, and do the filtering on the DB engine, rather than
with CF (which
is not very good at bulk data processing, as you're seeing.
It's not what
it's designed for).
I find QoQ to be very flaky for all ut the most basic
operations. For
basic stuff it's fine. It does not surprise me that it seems
to leak
memory (or whatever it's doing) and eventually give up the
ghost. This
does not help you, I realise, but as a suggested practice:
don't expect too
much out of QoQ. Try some other method instead.

A strange query of queries bug in CF11?

Hi,
I have this strange query of queries result that could be a bug in CF11. The result is fine in CF10.
Basically, I have 2 queries, qrA and qrB. I do a join of the two in joinQr, after which I do a query of qrA. Since I didn't alter qrA in any way, I would expect newQrA to give me the same result as qrA. However it only gives me one row ("D"). Now, here's the strange thing: If I start off qrA with the letters in ascending order ["A", "B", "C", "D"], then newQrA gives me the right result.
<cfset qrA = queryNew("")>
<cfset queryAddColumn( qrA, "size", "varchar", [ "D", "A", "B", "C" ] )>
<cfset qrB = queryNew("")>
<cfset queryAddColumn( qrB, "size", "varchar", [ "A" ] )>
<cfset queryAddColumn( qrB, "quantity", "integer", [ 0 ] )>
<cfquery name="joinQr" dbtype="query">
    select qrA.*, qrB.quantity
    from qrA, qrB
    where qrA.size = qrB.size
</cfquery>
<cfquery name="newQrA" dbtype="query">
    select *
    from qrA
</cfquery>

For your interest, by coincidence, my first test was with
<cfset queryAddColumn( qrA, "size", "varchar", [ "A","B","C","D" ] )>
It turns out that the order "A","B","C","D" works, whereas "D","A","B","C" fails. Quite funny, really.

Query of queries disallows SQL right() function

We're attempting to do a query of queries using the SQL
right() function like this:
select *
from getresults
where right([key],charindex('\',reverse([key]),1)-1) not in
(#quotedvaluelist(getexcluded.file_name)#)
We've even replaced that where clause with a much more simple
where right([key])='m'
just to make sure that it wasn't the nesting functions that
were causing the problem.
In either case, we get the error:
Query of Queries syntax error.
Encountered "right" at line 0, column 0. Incorrect
conditional expression,
Expected one of [like|null|between|in|comparison] condition,
What SQL functions are disallowed from query of queries?
Thanks,
Kris

Nasty stuff huh. Just happened to discover myself today that
Left doesn't work. I'd suspect that Aggregate functions are the
ONLY ones that will work. It would have been nice if they'd at
least allowed CF vs DB functions in their own "database" language.
BTW, also discovered that Count() returns Null rather than 0
when there aren't any per your WHERE clause.

Query Of Queries : Error When Trying To Fake Left Outer Join

Hi there
I am trying to replicate a left outer join, combining two query of queries using a method I located here
However, I keep getting an error message..
Here is the code I am using....
    <cfquery dbtype="query" name="qry">
                SELECT *
                FROM returnQry, returnQry2
                WHERE returnQry.mediumImage = returnQry2.mediumImage
                ORDER BY returnQry.name
            </cfquery>
            <cfquery name="returnQry3" dbtype="#application.mx#">
                SELECT *
                FROM trackmeanings AS t
            </cfquery>
           <cfquery dbtype="query" name="endQry">
                SELECT name,nameRcd,mediumImage, COUNT(sMessage) AS comments
                FROM qry, returnQry3
                WHERE qry.name = returnQry3.sNameTrack
                UNION
                SELECT name,nameRcd,mediumImage, COUNT(sMessage) AS comments
                FROM qry, returnQry3
                WHERE #qry.name# NOT IN (#QuotedValueList(returnQry3.sNameTrack)#)
                GROUP BY name,nameRcd,mediumImage
            </cfquery>
When I try to use the query output in a page, i get the error message "Incorrect conditional expression, Expected one of [like|null|between|in|comparison] condition"
Would anyone have any ideas?
Many thanks

Actually , spoke a little too soon, my query now seems to be outputting duplicates when the value is found on both sides of the union, my group by clause doesnt seem to be eliminating them like it usually does.
My SELECT code now reads
<cfquery dbtype="query" name="endQry">
SELECT name,nameRcd,mediumImage, COUNT(sMessage) AS comments
FROM qry, returnQry3
WHERE qry.name = returnQry3.sNameTrack
GROUP BY name,nameRcd,mediumImage
UNION
SELECT name,nameRcd,mediumImage, 0 AS comments
FROM qry
WHERE qry.name NOT IN (<cfqueryparam
value="#returnQry3.sNameTrack#"
cfsqltype="cf_sql_varchar"
list="yes"
/>)
GROUP BY name,nameRcd,mediumImage
ORDER BY name DESC
</cfquery>
and my ouput...is producing duplicates
<cfoutput query="rc.qryTopTracks" group="name">
#rc.qryTopTracks.name#
</cfoutput>
Would you have any idea of how to eliminate them here? Thanks

SUBSTRING in query of queries

Hi,
In a query of queries, can we do something like:
<cfquery name="differentValuesFirstGroup"
dbtype="query">
SELECT DISTINCT SUBSTRING(#firstGroup#,1,1)
FROM attributes.query
</cfquery>
I've tried SUBSTRING, SUBSTR, Left, but none of them seems to
work...
Any idea?
Thanks

No. But there are other ways to accomplish that.

ORDER BY FIELD, Query of Queries

Hi, is ther any substitution for this query in CF Query of
Queries?
SELECT * FROM table1 ORDER BY FIELD(col_1, 'apple', 'orange',
'banana')
Query of Queries do not support FIELD but I need a query
ordered in a specific way and i would rather not add a field to my
table for this simple query

Your syntax is not standard sql. There might be a db that
supports it, but none that I know of.
Depending on what you are trying to accomplish, you can
derive your sort column in your initial query. You might not even
need a Q of Q. Maybe something like this:
select case
when col_1 = 'apple' then 1
when col_1 = 'orange' then 2
when col_1 = 'banana' then 3
end as sort_column
from etc
order by sort_column
