Query of queries in a function
I call my report through a command such as the following:
<cfquery name="myquery">
select * from somewhere
</cfquery>
<cfreport template="myreport.cfr" format="flashpaper"
overwrite="no" query="#myquery#">
<cfreportparam NAME="commdate" VALUE="#commdate#">
</cfreport>
Then inside the report, I am trying to perform a query on the
query "myquery" but it says it can not find that query.
I'm thinking that if I do the query inside the report rather
than on the calling page, it would probably work, but it helps me
greatly to do my query on the calling page rather than inside the
report....
Is there something I am missing that can make this
possible?
Hi!
Okay I did retest this.
if you have following setup:
Table A
client_id Contact_dates
123 01.04.2010
124 02.04.2010
124 01.04.2010
Table B
client_id info_id
122 122
125 125
124 124
126 126
then you can do this via Desktop Intelligence - If you have the possibility to change the universe or sql - you should try to do there your stuff.
So basically you create a dataprovider for Table A : Client_ID .. Dimension, Contact_Dates .. Information for Client_ID.
For Table B: Client_ID .. Dimension, Info_ID .. Information for Client_ID
Now you can join the Client ID from Table A and B.
Create a report table in Deski with following columns:
Client ID ; Contact Dates (where contact dates is filled with this variable: =Max(<Contact_dates>))
Add a variable: = If (IsNull(<info_id>)) Then 1 Else 0
Now add a filter on the table: where the variable is 0
Now you will only see the Clients in Table B and for each client ID you will have only one entry.
I hope this is what you wanted to find.

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:
<!--- Simulated query; similar to what I was calling from
my database --->
<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#">
<!--- ========== END OF CODE ========== --->
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 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,
KrisNasty 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. -
In Query of Query, can't use LEFT() function?
Hi All,
I've got an LDAP query that I use for our employee directory. I then do a Query of Queries and do LEFT(SN,1) to separate out by first character of last name [A,B,C,D,E...] etc.
I had this working just fine in Railo CFM, but now I'm using Adobe CF and can't get that to work. I'm on CF9 Standard.
I've read the Query of Queries guide, but didn't find anything helpful there. Even when I do
'#LEFT(SN,1)#' as FirstCharacterOfLastName in my query, what I get is the value for the last row, not the value of each row as it's looping through the recordset.
Am I missing something? Any way to get that to work? Is that addressed in CF10?
thx.BenYou need to understand two things:
1) any CFML in your SQL string within a <cfquery> tag pair is processed by CF before the SQL string is passed to the DB driver. So your #left()# expression won't be processed "per row", because it's processed before the DB engine does any "per row" operations.
2) QoQ's SQL support is tragically minimalist. This lists all the functions it supports:
http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec0e4fd -7ff0.html#WSc3ff6d0ea77859461172e0811cbec0e4fd-7fcc
With the addition of two string functions: UPPER() and LOWER(). Oh, and CAST() (if that can be seen as a function).
That's it. That page in the docs describes all the functionality QoQ has. There's nothing missing 9as far as I know). That's it. There's not much to it.
I've been lobbying Adobe for a number of years to pull finger and improve QoQ to the point that it's more than just a curio, but they don't seem interested.
As to why your code works on Railo? Railo does some weird things, and doesn't stick to the precedent Adobe dictates their language should follow. Depending on who you talk to, this is either a feature or a barrier to entry (I'm mostly ambivalent, but err towards the latter camp). But perhaps Railo's QoQ processor supports LEFT().
Basically... you're gonna have to approach this differently: loop over the query with <cfloop> (etc) and update it row by row. This is pretty much what QoQ is doing anyhow, so I don't think you'll see a performance degradation. Well: you won't... because you can't do what you want to do with QoQ at all, I guess ;-)
Adam -
Is there a way to combine their query results into a single function
say I have a bunch of functions that return a query:
<cffunction name="getDeals" access="remote"
returntype="query">
<cffunction name="getDeals2" access="remote"
returntype="query">
is there a way to combine their query results into a single
function that returns a struct of the various results?Umm, it's probably more suited to an array - effectively
making it into a list of queries. You'd then loop the array and
output each.
I use a similar approach when creating system messages to the
user. Most of my functions that are called do their bit, then at
the end call another function I call "messages". This function
grabs whatever my function sends and appends it to a messages
array.
This way enables me to output a long list of messages -
because I could be calling several functions at the same time. If I
just output a message from each function, each one would overwrite
the other. So I'd get one message at a time.
Immediately after it's output, I then destroy the message
array so that old messages aren't kept inside of it.

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 ! ! ! ! -
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 ;-)
Adam -
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> We need more information than that to display a record,
so we select
> everything out of the database (which is fairly quick),
then JOIN that to the
> verity results (WHERE auctionID = KEY).
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("")>

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 thanksActually , 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 -

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.

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?
ThanksNo. But there are other ways to accomplish that.

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?
ThanksI 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?

Why full index scan is faster than full table scan?
Hi friends, In the where clause of a query,if we give a column that contains index on it,then oracle uses index to search data rather than a TABLE ACCESS FULL Operation. Why index searching is faster?
