How should i use the two results sets in one single report data region?

Hi frnz,
I have to create a report using the below condition...
Here my given data set query gives you the two result sets ,so how should i use that two result sets information in single report....when i accessing that data set query it will take the values off the first result set not for the second result set.
without using sub report and look up functionality..... if possible
is there any way to achieve this.....Please let me know..
Thanks!

You cant get both resultsets in SSRS. SSRS dataset will only take the first resultset
you need to either create them as separate queries or merge them into a single resultset and return with ad additional hardcoded field which indicates resultset (ie resultset1,resultset2 etc)
Then inside SSRS report you can filter on the field to fetch individual resultsets at required places. While merging you need to make sure metadata of two resultsets are made consistent ie number of columns and correcponding column data types should be same.
In absence of required number of columns just put some placeholders using NULL

Create a CF Query Result Set in Java

I'd like to programatically build a ColdFusion query resultset inside of a Java class and return it to the calling application. See the Java psudocode below to see what I'm talking about:
public class MyClass {
 public coldfusion.sql.QueryTable getQuery() {
 // Create a query table object
 QueryTable myTable = ..?
 // Loop through some set of instance data for my class
 for(int c = 0; c < this.myWigets.length; c++) {
 int row = c+1;
 myTable.setField(row, nameCol, this.myWigets[c].name);
 myTable.setField(row, colorCol, this.myWigets[c].color);
 return myTable;
I've had stuff like this partially working in the past but had issues with things like query of queries and such probably due to the hacks used to create the QueryTable object. I'm mainly just checking in to see if there has been any progress made in this area. To me this seems like such an obvious thing for a Java developer working within CF to want to do. I'm surprised Adobe doesn't have an officially supported API for doing this sort of thing (or maybe I'm just too dumb to find it.) A few other notes... I'm not using CFX, and I'm not starting with a java.sql.ResultSet otherwise I would use the QueryTable(java.sql.ResultSet) constructor. I need to build this thing from scratch programatically.
Thanks for your time. I hope this question makes sense to someone out there.
- Mike

I appologize. I wasn't very clear with my original question.
I'm creating an instance of my Java class from within CF using createObject("java", "com.example.MyClass"). So based on the sample code in my original post on the CF side I'd like to do something like this:
<cfscript>
 myObj = createObject("java", "com.example.MyClass");
 myObj.doSomeStuff();
 myCFQuery = myObj.getQuery(); // Return a CF query from my java class
</cfscript>
... then do stuff like ...
<cfquery name="mySortedQuery" dbtype="query">
 select *
 from myCFQuery
 order by color
</cfquery>
I appriciate your suggestions so far. I have other solutions working already but they are not ideal. I was just hoping someone had a clean and as-hack-free-as-possible way of creating a ColdFusion query result set in Java and passing it back to CF.
Thanks again,
Mike

How to get previous row of result set in select query?

I want to access the previous row of an result set obtained yet, in the same selectquery .
How can I do that?

Use analytical functions.
For example:
create table top_n_test (
 a number,
 b varchar2(10)
insert into top_n_test values (1, 'one');
insert into top_n_test values (2, 'two');
insert into top_n_test values (3, 'three');
insert into top_n_test values (4, 'four');
insert into top_n_test values (5, 'five');
insert into top_n_test values (6, 'six');
insert into top_n_test values (7, 'seven');
insert into top_n_test values (8, 'eight');
insert into top_n_test values (9, 'nine');
commit;
select a, b from (
select
 a,b,
 rank() over (order by b) r
from
 top_n_test
where
r<4;
 A B
 8 eight
 5 five
 4 fourHTH

How to Add extra data in result set of cfquerry?

hi all,
I am new to cold fusion please help me
i am using the cfquery tag for executing a select query and getting the system name and system is from that........
But i want an extra system name and system id to add to the result of that query with out changing the data base ..............
please any one suggest me ...........IT's URGENT
Thanks in advance
Sudheer

You'll have to use an array and the function queryAddColumn. An example follows.
Suppose I have a result set called myQuery. There are 5 rows in it. I wish to add 2 new columns to the query, on the fly. The column names are username(type varchar) and userID(type integer)

<cfset usernameArray = ArrayNew(1)>
<cfset usernameArray[1] = "[email protected]">
<cfset usernameArray[2] = "[email protected]">
<cfset usernameArray[3] = "[email protected]">
<cfset usernameArray[4] = "[email protected]">
<cfset usernameArray[5] = "[email protected]">

<cfset columnNumber = queryAddColumn(myQuery, "username", "VarChar", usernameArray)>

<cfset userIDArray = ArrayNew(1)>
<cfset userIDArray[1] = "23">
<cfset userIDArray[2] = "121">
<cfset userIDArray[3] = "9">
<cfset userIDArray[4] = "76">
<cfset userIDArray[5] = "44">
<cfset columnNumber = queryAddColumn(myQuery, "userID", "integer", userIDArray)>

How do I break up a result set over various pages?

I would like some example code of how to breakup a result set that I am using in a form.
There are too many results for the form to currently work properly on one page so I have to do it over several web pages, using a next page link etc...
I am currently using servlets.
If anyone has an idea of how to do this differently have at it and let me know what to do. I prefer code examples.

I would change the select query so that it doesn't return the whole resultset. Check your database manual to see if your database supports something like limit. E.g. this query will only return the 20 first records if you are using mysql.
select *
from tablename
limit 0,20

How to create count() measure for certain set of records in BMM Layer

Hello all.
I have a logical table like this one (Table AAA)
Table AAA

--------------------------+
| *Key* | *Name* | 
--------------------------+
| 1-2EMHS9 | AAA |
--------------------------+
| 1-2EMWMO | BBB |
--------------------------+
| NULL | CCC |
--------------------------+
I need to calculate count() of records where Key is not NULL. In this example, this field must return coun() = 2.
I suppose, CASE operator may help me with that, but I do not know for sure how to do this.
Thank you for help,
Alex.

Thank you.
But I must concretise my issue.
I need to calculate number of records (e.g. order_id) that sutisfy appropriate condition (one of columns (e.g. loy_member_id) is set to null).
I created logical column, that returns order_id if condition (loy_member_id is null) is met.
Look at my logical column:
Q Orders (LPM) - must return number of orders where loyalty_member_id is null.
It has an expression:
CASE WHEN NOT "Foxtrot (my) replica"."Sales Orders".LOY_MEMBER_ID IS NULL THEN "Foxtrot (my) replica"."Sales Orders".ORDER_ID ELSE NULL END
So, this returns order_id I need.
But the question is how to count number of order_id's returned by this column on BMM Layer.
When I define my column with next expression:
*COUNT(CASE WHEN NOT "Foxtrot (my) replica"."Sales Orders".LOY_MEMBER_ID IS NULL THEN "Foxtrot (my) replica"."Sales Orders".ORDER_ID ELSE NULL END)*
I receive error:
+[38083] The Attribute 'Q Orders LPM' defines a measure using an obsolete method.+
Thank you,
Alex.

Creating XML from large result sets

We are trying to create XML docs from queries that return somewhere in the neighborhood of 13000+ rows, each with as many as 30 columns. It seems someplace deep within the xmlgen utility or the xsu methods, we throw an OutOfMemoryError. This happens whether we run as a java stored procedure, a pl/sql stored procedure, pl/sql script or java servlet. It looks like the top of the stack shows the problem occurs trying to extendCapacity in a StringBuffer. We're running 8.1.6 with java 1.2.2 and xsu 1.2. Has anyone had to query large amounts of data like this and if so, how did you go about it? Is there a slick way to break things up and then string everything back into 1 big xml doc? Any help would be greatly appreciated. Thanks.

I guess you can use pagination,
either using xsu or Top N Queries and then you could merge all the pages in an unique XML or DOM tree prior to persist it to disk.
With XSU:

How to create list of string from set of parameters?

Hey,
I have query methods who gets set of parameters for example:
getUser(String userName, int userAge)I use in int because this field is not null!!!
I want to create a general auditing method - the auditing method get list of query param names and query param values, so i need to create a generic method that get set of valus (can be from any type) and return List<String>.
Array.asList will not work because i have primitive types (like int)
Thank you

I wrote a helper for this.
I dont know if there is supported helper in java.
 public static List<String> getStringList(Object... arguments)
 List<String> list = new ArrayList<String>();
 for (Object object : arguments)
 if (object == null)
 list.add("NULL");
 else
 list.add(object.toString());
 return list;

WHERE UPPER(TRIM(RESULT)) = 'COMPUTER SCIENCE'
GROUP BY grecode(titleid),
         toeflcode(titleid)Please note that applying functions like UPPER and TRIM on a string literal can and should be avoided.
For example:
UPPER(TRIM('USA')) = 'USA'Why force the database to do both an UPPER and a TRIM on something that can just be represented in uppercase with no surrounding spaces? It's a waste of time.

How to create a people picker type metadata in a document set?

Hi folks,
I want to create a people picker type metadata in a document
set (it has some content types and it resides inside a library).
So please help me knowing steps for creating it.
Our web application is using classic based authentication therefore I want to retrieve the names and groups in people picker column from Active Directory.
Also, the document set library for which I want to create people picker metadata did not had document set before and documents where saved directly in content types as well as the metadata that now we are making as people picker was before of type Single line
of text.
So, whether after creating it of type people picker, at the time of moving documents into document set, it will create problem? If yes,than of of what kind and how can it be resolved?
Replies will be greatly appreciated.
-Ishita

Hi,
From your description, I know you want to add a people picker column in a document set, then add this document set into a document library.
If you want to add a people picker column in a document set you should create a document set first. You can know how to create and configure a document set by referring to this article: https://support.office.com/en-us/article/Create-and-configure-a-new-Document-Set-content-type-9db6d6dc-c23a-4dcd-a359-3e4bbbc47fc1.
After creating a document set, you can follow these steps below to add a people picker column in a document set: click Site Actions -> Site Settings -> under Galleries section, Site content types -> find the content you want to add people
picker column -> under Columns section, Add from new site column -> Name and Type, enter your column name and choice Person or Group -> OK.
If you move documents into document set, it will keep the current properties. You can edit properties to change the document to another content type which is contained in the document set.
In my case, DocA is the content type of the document library, Document and DocB are content types of the document set.
If I have mis-understand, please let me know.
Best Regards
