Is it possibly to modify certain rows of the output table in a SAP infoset query? If yes, how? I already tried writing some code for that in the coding tab in the infoset (at the end of selection - after the list) but I was not able to reference the table or fields.

I am currently working with Oracle Forms and I have made a dynamic query which is being passed on to the Set_Block_Property() and then the query is Executed. The output is ordered by using the 'Order By' option in Property Palette of respective form.
My requirement is to limit the number of records and when clicking the next button, It has to show the next set of records. I have been using the 'maximum records fetched' property in the Form Palette; however, I came across the OFFSET and FETCH clauses in Oracle 12c R1 (12.1), which do this with ease.
Is it possible to use the same with Oracle Forms Developer? Any answers or references would be appreciated. Thank you in advance.
At block level you got an option Query Array Size
This is the number of records fetched from the database.
I am newbie to BIRT and unfortunately my first task is over complicated.
I want to create table like this
Birt Report Snap
the columns in this picture must be dynamic. the data for the column name is in database and I have to fetch it and create columns on the go. 2nd to put values against it.
kindly tell me if this thing is doable in birt. I am new to this so please don't give negative ratings
thanks.
I believe what you are looking for is called a Cross Tab Table.
Here is a tutorial video on it: BIRT - Cross Tab Table
In addition to SBurris answer, which is the way you should try first, I can assure you from my experience that what you want is in fact doable with BIRT, and even in two different ways.
However, some of the minor aspects might be a bit quite tricky for beginners, e.g. the merged cells in the column header, the different background colours and border widths for the columns. So, these style aspects shouldn't matter at first, you can tackle them later.
The first, by far easiest and standard way to achieve this kind of report layout is a cross tab, as SBurris said.
The second option is - depending on the database backend - to use a "normal" Table report item in they layout and to "create the cross tab" with SQL.
This is more powerful IMHO as the BIRT Cross Tab report item, but also more complicated.
For examples, see here:
Pivot / Crosstab Query in Oracle 10g (Dynamic column number)
Pivoting rows into columns dynamically in Oracle
How to do Pivoting in Oracle 10g
(you get the idea)
To use this with BIRT, you'll have to select the column title values in addition to the cell values.
You have to decide how many columns do/should fit on your page (if you're using PDF output).
You can use the maximum aggregate function in the visibility expression of the columns to hide empty columns.
If the number of logical columns exceeds the number of columns for a single page, you can extend the idea further by dividing the cross tab into several, each with at most N columns.
However, note that this approach will need an experienced BIRT developer...
I'm using Toad for Oracle 12.5 and a little thing anoy me : when I look into the "Data" tab of a table, the row order is all jumbled up.
On any other DB software I used (SQL developper, phpmyadmin, etc), the default data view would retur the rows ordered by the primary key
So, I would like it to automaticly by default sort the data in the "Data" tab of each table to the first column, or even better, to the table primary key.
I've looked in the options but I can't see anything related to this.
Have some of you had the same problem ?
No oracle client that I have seen ever tacks an "order by" onto a statement on its own accord. It returns what the query returns in the order (or lack thereov) that it receives it.
Now it may LOOK ordered if the rows were inserted in order, but that is a fluke. Period.
And frankly, I'd be upset if a UI arbitrarily added expensive sorts to my queries unless I specifically told it to.
I have some BIG tables. presuming that I want the UI to take the time to scan the index and grab the lowest PK values just because I opened the DATA tab? No. Dear me - NO!
If I want it ordered, I will open the sort/filter dialog and specify so, or click on the appropriate column header to sort the results.
ADDITION:
If there ARE some tables where you want this behaviour (I can see the convenience if checking code tables for example), then use the sort/filter dialog on the data grid for that table to set an order by and TOAD will remember that setting for that table in this schema until you remove it. So you CAN set this behaviour where you want and not deal with the performance aspects where you don't.
Here's the scenario:
Say you have a Hive Table that stores twitter data.
Say it has 5 columns. One column being the Text Data.
Now How do you add a 6th column that stores the sentiment value from the Sentiment Analysis of the twitter Text data. I plan to use the Sentiment Analysis API like Sentiment140 or viralheat.
I would appreciate any tips on how to implement the "derived" column in Hive.
Thanks.
Unfortunately, while the Hive API lets you add a new column to your table (using ALTER TABLE foo ADD COLUMNS (bar binary)), those new columns will be NULL and cannot be populated. The only way to add data to these columns is to clear the table's rows and load data from a new file, this new file having that new column's data.
To answer your question: You can't, in Hive. To do what you propose, you would have to have a file with 6 columns, the 6th already containing the sentiment analysis data. This could then be loaded into your HDFS, and queried using Hive.
EDIT: Just tried an example where I exported the table as a .csv after adding the new column (see above), and popped that into M$ Excel where I was able to perform functions on the table values. After adding functions, I just saved and uploaded the .csv, and rebuilt the table from it. Not sure if this is helpful to you specifically (since it's not likely that sentiment analysis can be done in Excel), but may be of use to anyone else just wanting to have computed columns in Hive.

You can do this in two steps without a separate table. Steps:
Alter the original table to add the required column
Do an "overwrite table select" of all columns + your computed column from the original table into the original table.
Caveat: This has not been tested on a clustered installation.
I am using SSRS through VS 2010 and have the following questions:
Can I define a drop down menu without defining a dataset?
I have a dataset defined, is there anyway to add "manual" values to this dataset? The background requirement of this is that the report query is based on this dataset. However I want to have an option in the dataset where it says "all" in order to allow the user to see everything instead of narrowing down results based on the dataset.
Thanks,
Bruce
I am a newbie to SQL Server reports and found my answers:
For the first one, can simply create a table and use a dataset on the created table with customzied values.
Same goes for the second one, the manual data can be added to the table itself.
