Query that only returns certain fields in Java

Currently I'm using a filter that identifies some keys, I then get all the keys and get a single value from each object. The rest of the object is quite large. I've seen references in passing on the ability to do this, using CohQL but I can't get it to work from Java.
Basically, I want to do: "Select field from "Cache" where key='asdf'". I just want to get back the specific "field" rather than the whole object. How do I do this?
Thanks.

Hi,
It should be easy if your object has a getField() accessor. Hope this helps ...

Using Path-Expressions
One of the main building blocks of CohQL are path-expressions. Path expressions are used to navigate through a graph of object instances. An identifier in a path expression is used to represent a property in the Java Bean sense. It is backed by a ReflectionExtractor that is created by prepending a get and capitalizing the first letter. Elements are separated by the "dot" (.) character, that represents object traversal. For example the following path expression is used to navigate an object structure:
a.b.c
It reflectively invokes these methods:
getA().getB().getC()
For example ...
Select the home state and age of employees in the cache ContactInfoCache, and group by state and age.
select homeAddress.state, age, count() from "ContactInfoCache" group by homeAddress.state, age

Query that only returns items that will produce a result

Thanks to Mack for his help yesterday. I would really appreciate some help from anyone who is more SQL competent than I am. I have an SQL problem that is just completely over my head. I've created a nifty tagging system for the blog, that sorts by tags and by multiple tags, check out the beta here: http://committedsardine.com/blog.cfm
When a user selects a tag, it adds it to the value list SESSION.blogTags. If the selected tag is there already, it removes it. When the list for tags pops up, I output all the tags, and show their state. You'll see what I mean if you try it.
What this leads to is the ability to select a group of tags for which there are no query results. What I want to do is only show those that will generate results and how many results they'll show. Like this, select "fluency" by itself there are 310 entries
fluency (310) | digital (234) | writing (12)
Once fluency is selected, there are 13 articles that ALSO are tagged by "digital", but none that are tagged by writing:
fluency | digital (12) | writing
I have a table called blogTagLinks, that is just for tying a tag to a blog. It lists a blogID and a tagID. Here is a sample of it for reference:
blogTagLinkID
blogID

            </cfif>
     </cfif>
ORDER BY blog.blogDate DESC

There might be a single query solution but here's a query that you
will need to run for each tag in the database (cfloop over all the
tags) and will give you the number of blogs that have the selected
tags + the current tag
SELECT Count(*) AS blog_count
FROM (
    SELECT blogID
    FROM blogTagLink
    WHERE tagID IN(<cfqueryparam cfsqltype="cf_sql_integer"
value="#SESSION.blogTags#" list="true">)
         OR tagID = #currentTagID#
    GROUP BY blogID
    HAVING count(tagID) = #ListLen( SESSION.blogTags )#
         OR count(tagID) = #ListLen( SESSION.blogTags )# + 1
    ) AS blogs

Need help writing a MySQL query that will return only records with matching counter-parts

Since I don't know how to explain this easily, I'm using the
table below as an example.
I want to create a MySQL query that will return only records
that have matching counter-parts where 'col1' = 'ABC'.
Notice the 'ABC / GHI' record does not have a
counter-matching 'GHI / ABC' record. This record should not be
returned because there is no matching counter-part. With this
table, the 'ABC / GHI' record should be the only one returned in
the query.
How can I create a query that will do this?
id | col1 | col2
1 | ABC | DEF
2 | DEF | ABC
3 | ABC | GHI
4 | DEF | GHI
5 | GHI | DEF
*Please let me know if you have no idea what I'm trying to
explain.

Please be more clear. You say that 'ABC / GHI' should not be
returned,
and then you say that 'ABC / GHI' should be the only one
returned. Can't

Only show certain fields after a date has passed

How would I set a recordset to only show certain fields after
a date has
passed?
For example:
I have a list of classified adverts some which include an
image which the
client pays extra for. After a certain time period, say, 1
year,
would it be possible to use some kind of IF statement (or
something) to no
longer show the image?

Search Scope that Only Returns Sites

I'd like to create a search scope that only returns Sites. I don't want any documents, lists, items, or anything else in my results. How would I do this?Murray

You can use ContentClass:STS_Web
You can either create a scope or you can simply append it to any query using the search query web part. This would allow the user to search for "project1" and the executed query would be "project1 ContentClass:STS_Web" and therefor only return sites with project1 in the content.

Hi
I am trying to wright a SQL query that will return the date the timesheet was submitted and date/time it was approved, can anyone guide me on this?
I basically need person name who submitted, date - time it was submitted for approval, then the person who approved it and the date - time that it was approved
Thanks

Ruby,
you can start with HXC_TIMECARD_SUMMARY table for submitter detail. But for approver details, i think you need WF tables to get the data for item type HXCEMP.

Universe object that points to certain field according to the user PVL

Hi universe designing experts !
Marianne solved a problem I have in [this|Web Intelligence: Hide / Show object according to InfoView Locale; post. I wanted to replace an object/column in a report according to the users locale. This was done at report level with a selection containing the getPreferredViewingLanguage() function in WebI.
My question now is, could I somehow define in the universe an object that, according to the PVL of the report viewer, points to a different field in the database ?
We have description fields in the databse for different languages.
Thanks in advance !

OK I didn't know that. But I don't think that I could use this variable in this situation. Please correct me if I'm wrong...
What I want to do is this:
A user with Preferred Viewing Language nl_NL and a user with PVL en_GB are requesting the same report. In that report there is a field with a description about another field. The descriptions are 2 different columns in the database. You showed me before (thanks again) how I could switch the 2 field according to a users PVL that I could query from the system ( getPreferredViewingLanguage() ). I want, if possible, to do this at Universe level so I only have to drag 1 single object in the query that corresponds to the right column according to the report viewers PVL... So the en_GB guy will see English descriptions and the Dutch guy will see the Dutch descriptions all from the same object...
Would be cool if that was possible...
Thanks again for helping !

Form Query button only returns current user's entries.

Hello.
I've built a simple form that admins will use to insert some simple information into a table with. They'll insert the names of users, passwords, company info, email, logged in data and created time/by, updated time/by info. The inserting part works fine, but when they query the form, all they get are the records that they've entered. Any records that another user has entered do not show up. A report based on the same table shows all users in the table. The only thing I'm doing that may be of any problem is inserting created by and updated by as a hidden field and defaulting that value to wwctx_api.get_user. I don't see why that should be a problem. Is this a table permissions issue? I've provided manage access to all users of the form.
Thanks.
Kurt

Ton,
Shouldn't I be able to run that api as a default value for hidden fields, without it impacting the query? I've only attached that value to the created by and updated by columns and made the first insertable only and the second updateable, insertable. I guess I understand. I thought the default value would only be used for new entries, not for all queries. I guess I need to put in a request to our data modeler to add a trigger to the table (my hands are tied for table creation). Actually, I should be able insert some pl/sql code to the portlet to do this. Something to do with the ...after the processing the form option? After inserting the new record through the form, insert created by, created date or update updated by updated date. One thing I still don't get (having only worked with Portal a few days) is how do I make sure I'm associating this insert with the proper record? Thanks.

SQL: Select DISTINCT only on certain fields?

This is an odd question. Partly because it's late and I'm not
thinking
straight, but...
I have a query consisting of 9 joins. It works fine.
However, I've encountered a bit of an issue with my data that
would much
easier to fix via a query than actually fixing the data (as
the data fix
would require committee approvals and the like...)
In a nutshell, my query is trying to return a DISTINCT set of
recrods.
The catch is that my records are ALMOST distrinct, except for
one field. Is
there a way to use the distinct command in a way the excludes
specific
fields?
-Darrel

> No; DISTINCT applies to all columns returned by your
SELECT statement.
> You didn't provide a lot of information, but typically,
if you need
> DISTINCT, then you've done something wrong.
It's a complex join. The data is this:
Packet table (record of a packet of forms)
which point to...
Packet variations (each packet can have a variation)
which point to...
Forms table (record of a form)
which points to...
Form variations (individual forms)
The catch is that multiple Packet Variations can point to the
same Forms, so
when I query the database to get all variations of a packet
and related
forms, I can end up with duplicate records of forms.
This isn't a big deal, as DISTINCT can work for this. The
catch is that we
also let each Packet Variations' forms be sorted
individually. It's this
'sort' field that ends up causing the Distinct not to work,
as the sort
might be completely unique for each one.
ALL THAT SAID, this is definitely more of a policy issue than
a technology
issue. However, getting them to change policy is sometimes
more work than
finding a technology workaround.
I could just query the DB and return all the duplicates and
then sort things
out in the code, but I was hoping that maybe there was a
clever way to
handle this via SQL.

Generating subtraction equations that only return positive values

Hello!
Can you please help me to create a random subtraction equation where the result will always be positive? For example, my current scripting will return something lilke 3-6=-3. I don't want equations like this- only postive answers.
Thanks for your help!
//random numbers
//1.
function randomNumbers(min:Number,max:Number) {
   var Results:Number=Math.floor(Math.random()*max)+min;
   return Results;
//2.
new_mc.addEventListener(MouseEvent.CLICK, showRandomnumber);
//3.
function showRandomnumber(event:MouseEvent):void{
   r1_txt.text = String(randomNumbers(1,10));
   r2_txt.text = String(randomNumbers(1,10));
   a1_txt.text = String(Number(r1_txt.text) - Number(r2_txt.text));

I see.
How about you try to pass the first generated value the second time you call the function? Like so:
// Your function definition.
function randomNumbers(min:Number,max:Number) {
   var Results:Number=Math.floor(Math.random()*max)+min;
   return Results;
// Connecting the event handler.
new_mc.addEventListener(MouseEvent.CLICK, showRandomnumber);
// Check the r2 line.
function showRandomnumber(event:MouseEvent):void{
   r1_txt.text = String(randomNumbers(1,10));
   r2_txt.text = String(randomNumbers(1,r1_txt.text as Number));
   a1_txt.text = String(Number(r1_txt.text) - Number(r2_txt.text));
Ofcourse, this leaves you with the possibility that r2 is the same as r1, leaving 0 after subtraction. But it shouldn't give you any negative numbers.

Problem with select query that includes a date

I've been fighting with this for about 4 hours - yes, quite literally... I've never been good with date stuff. I have a brain block.
Anyway, here's the situation:
I have an Access database that has a time/date field. There are no times, just a date in mm/dd/yyyy format.
That table is a list of classes held for the past three years. I want to make a query that only shows the classes that have ended after January 1 of this year. I don't want to put 01/01/2010 in the query itself because I want it to still work next year.
This is the current query:
<cfquery name="classes" datasource="#DSN#" dbtype="ODBC">
SELECT classesTitles.ClassTitle, classesTitles.ClassDesc, classCatagories.catagoryName, classes.classStart, classes.classEnd, classes.classNotes, owners.fName, owners.lName, classTime.timeSlot, classes.classID, classes.classLimit
FROM classCatagories INNER JOIN (((classes INNER JOIN classesTitles ON classes.classTitle = classesTitles.classTitleID) INNER JOIN classTime ON classes.classTime = classTime.timeID) INNER JOIN owners ON classes.classInstructor = owners.ownerID) ON classCatagories.catagoryID = classesTitles.ClassType
WHERE classes.classEnd < 01/01/#DatePart("yyyy", now())#
ORDER BY classes.classStart, classCatagories.catagoryName, classTime.timeSlot, classesTitles.ClassTitle
</cfquery>
I don't get any results, but I should get a list of every class that has an end date before January 1 of this year - about 200 records.
When I swap around the where clause to:
<cfquery name="classes" datasource="#DSN#" dbtype="ODBC">
SELECT classesTitles.ClassTitle, classesTitles.ClassDesc, classCatagories.catagoryName, classes.classStart, classes.classEnd, classes.classNotes, owners.fName, owners.lName, classTime.timeSlot, classes.classID, classes.classLimit
FROM classCatagories INNER JOIN (((classes INNER JOIN classesTitles ON classes.classTitle = classesTitles.classTitleID) INNER JOIN classTime ON classes.classTime = classTime.timeID) INNER JOIN owners ON classes.classInstructor = owners.ownerID) ON classCatagories.catagoryID = classesTitles.ClassType
WHERE classes.classEnd > 01/01/#DatePart("yyyy", now())#
ORDER BY classes.classStart, classCatagories.catagoryName, classTime.timeSlot, classesTitles.ClassTitle
</cfquery>
I get EVERY class in the database, and I should only be getting about 50
The classes are about 8 weeks long, the begin date and end date are in the database as date/time fields, so I need to show everything that ended in 2010, regardless of when it started.
I'm sure it's something glaringly obvious, but it's escaping me.
THANKS
Michelle

The format of your date field in access is irrelevent to the situation at hand. Use proper date objects instead of trying to build a suitable string. For the first of January of the current year, the coldfusion functions createdate(), year(), and now() are your freinds. Then, in case Adam's post was not clear, use cfqueryparam with the resulting variable.

Cubeset to only return positive values?

Yet another cube formula question... In Excel 2010, no powerpivot or olap pivottable extensions, this is a pure Excel project.
I am building various cubeset, cubemember, and cubevalue formulas to validate an ETL process.
Question:
I need to create a cubeset that only returns the members of a cube that have positive values for a specific measure. This cubeset will then be one of several cubesets that gets fed into a cubevalue formula that would otherwise exceed the 255 char limit.
I can create a cubeset for the overall measure:
=CUBESET("MyCube","[Measures].[RetailPrice]")
but haven't found the right syntax for limiting results to only those that have positive values, I think it would be something like:
=CUBESET("MyCube","FILTER[Measures].[RetailPrice],[Measures].[RetailPrice]>0")
This syntax actually doesn't return an error, so maybe it is valid syntax... but when I wrap it in a simple cubevalue statement,
=CUBEVALUE("MyCube", A2) where A2 is the Cubeset above, or if I also add date range and other filters,
I get a #Value error, indicating that "the tuple is invalid" per
http://office.microsoft.com/en-in/excel-help/cubevalue-function-HA010342391.aspx?CTT=5&origin=HA010342384
I'm still a newbie with the cubeformula syntax and MDX, so I appreciate any suggestions!

Hi Rohit-
The cube has a net value of 1220 for the measure I'm trying to calculate (when I don't filter on > or < zero).
I tried my formula both ways (looking for just positive, and just negative values) and while both work in the standalone cubeset formula, neither return a value when I use it in a cubevalue formula.
My suspicion, other than a syntax error, is that this may have something to do with me trying to filter on the measure value(s), instead of a dimension- which I think must be possible, but again maybe not with this syntax.
Let's assume that we had a total of 1280 in retail price, but due to a few returns, we have a few records that show value of -60. If we were looking at profitability, the 1220 is what matters. If we are looking at "dollars exchanged" as a variable expense
driver of some other measure, then we'd actually want the absolute value of retail price (1280+60 = 1340). I hadn't been able to get the MDX ABS to work, so this was my attempt to grab the positive and negative numbers separately, and then add them to get
the equivalent of ABS.
In this case, slicers aren't a desirable option due to how the report is being constructed (I've used slicers in other reports with cubeformulas, but with Excel 2010 I have to have an extra pivot table to get the slicer value, which then has to get fed into my
cubeform and I'm back at step 1, getting it to work in the cubeformula syntax)
Thanks!
