Substr of date as Column name

Hi All,
Can we have substr(date) as column name. I am trying to create a query where in I need to achieve something like this
select s.xyz Today,
s.abcd "6 Months ago" || to_char(add_months(sysdate,-6),'Mon rrrr') ||')'
from sales_tab s
Any idea.
Thanks,

Ok.
Exactly what I was talking about. Creating a customized, date dependent column header in the report.

How to insert data into datagrid dynamically and also programatically with data and column names being retrived from a xml file..

iam not able to insert data into datagrid corresponding to the column names..as iam inserting both data and column names programatically..ie iam not able to co relate the data with the column names.plzzz help me asap

A DataGrid is row-based rather than cell-based with each row
corresponding to an item in an underlying collection (specified in the
dataProvider property). In order to add data to a DataGrid you
manipulate the underlying collection, rather than the grid directly.
Based on the limited description of your problem I would imagine you
would need to create dynamic objects with property names that correspond
to the dataFields of your dynamically created datagrid columns.
So if you had created columns with dataFields "alpha", "beta" and
"gamma" on your datagrid, you could create an item in your grid by
adding the following object to your dataProvider:
var gridItem : Object = new Object();
gridItem.alpha = "alphaValue";
gridItem.beta = "betaValue";
gridItem.gamma = "gammaValue";

Date as column names in a table

Set date as column name

Hi All. Does anybody know how to get the date of every Friday based on a given quarter and set it as the column name. For instance with quarter 1 the column names would be
1/6/2006
1/13/2006
1/20/2006
1/27/2006
etc
Thank you!

Hi,
Try something like :
1 select day# as FRIDAY
2 from
3 (select fist_day_q+rownum-1 day#
4   from
5   (select trunc(sysdate,'q') fist_day_q,
6           last_day(add_months(trunc(sysdate,'q'),2)) last_day_q
7    from dual)
8   connect by level <= last_day_q - fist_day_q +1)
9* where to_char(day#,'d')=5

Excel 2013 connect to a cube, and Power View concatenate the column name by default

Hi Guys,
Currently, we met a problem with excel services to connect to a cube, when we develope a Excel 2013 Powerview report, the data model column name is concatenate into terrible name by default. e.g. Dim TimeDate Date, Dim TimeTime HierachyYear -Month.
But when start up the data model with Powerpivot, everything gone well. We knew that it can be manual update the name as workaround, but we need to do it every time we create a new powerview with the data model.
Is that any other solution we can do with?
Please help.
Johnny

JTable can't display column names and scroll bar in JDialog !!

Dear All ,
My flow of program is JFrame call JDialog.
dialogCopy = new dialogCopyBay(frame, "Bay Name Define", true, Integer.parseInt(txtSourceBay.getText()) ,proVsl ,300 ,300);
dialogCopy.setBounds(0, 0, 300, 300);
dialogCopy.setVisible(true);        Then,I set the datasource of JTable is from a TableModel.
It's wild that JTable can diplay the data without column names and scroll bar.
I have no idea what's going wrong.Cause I follow the Sun Tutorial to code.
Here with the code of my JDialog.
Thanks & Best Regards

Reading MS Project column names and data on the fly from a selected View

Hi guys,
I have several views on my project file (MSPROJECT 2010) and I want to build a macro so that;
1. User can select any view ( Views can have diffrent columns and the user may add new columns as well)
2. User runs the Macro and all the coulmns along with the tasks displayed in the view will be written to a excel file. ( I don't want to build several macro's for each view, I'm thinking of a common method which would work for any selected view)
The problem I'm facing is that how will i read the column names and data for a particular view on the fly without hard coding them inside the vba code ?
The solution needs to work on a master schedule as well.
Appreciate your feedback.

Just to get you started the following code writes the field name and data for the active task to the Immediate window.
Sub CopyData()
Dim fld As TableField
For Each fld In ActiveProject.TaskTables(ActiveProject.CurrentTable).TableFields
If fld.Field >= 0 Then
Debug.Print Application.FieldConstantToFieldName(fld.Field), ActiveCell.Task.GetField(fld.Field)
End If
Next fld
End Sub

Calculation Field to be mapped to different data object's column name in Oracle BAM 12c

Hi,
I am having a challenge to enable drill down to 2nd level report by passing calculation field as parameter.
As an alternative, I am thinking to point calculation field to another data object’s column name and generate report so that I would be able to pass that as parameter to drilling report view.
Is there any way to map calculation field to different Data object’s column name? Thanks in advance.

How to read the data from an internal table,when column names are known

Hi All
I have a specific requirement. I got an internal table with many fields (let it be my_tab). Some of the fieldnames (column names in internal table my_tab) are stored in separate internal table(let it be my_fields).
I need to store/read data corresponding to the fields (whose name is stored in my_fields) from my_tab.
I am able to build dynamic table (referred by field-symbol) with respect to the given field names in my_fields.
But i am unable to read the data corresponding to the fieldnames from my_tab.
Please provide me some pointer in this regard.

How can i export the data to excel which has 2 tables with same number of columns & column names?

Hi everyone, again landed up with a problem.
After trying a lot to do it myself, finally decided to post here..
I have created a form in form builder 6i, in which on clicking a button the data gets exported to excel sheet.
It is working fine with a single table. The problem now is that i am unable to do the same with 2 tables.
Because both the tables have same number of columns & column names.
Below are 2 tables with column names:
Table-1 (MONTHLY_PART_1)
Table-2 (MONTHLY_PART_2)
SL_NO
SL_NO
COMP
COMP
DUE_DATE
DUE_DATE
U-1
U-1
U-2
U-2
U-4
U-4
U-20
U-20
U-25
U-25
Since both the tables have same column names, I'm getting the following error :
Error 402 at line 103, column 4
alias required in SELECT list of cursor to avoid duplicate column names.
So How can i export the data to excel which has 2 tables with same number of columns & column names?
Should i paste the code? Should i post this query in 'SQL and PL/SQL' Forum?
Help me with this please.
Thank You.

You'll have to *alias* your columns, not prefix it with the table names:
$[CHE_TEST@asterix1_impl] r

3      with data as (
4        select 1 id, 'test1' val1, 'a' val2 from dual
5        union all
6        select 1 id, '1test' val1, 'b' val2 from dual

Saving result from sp_executesql into a variable and using dynamic column name - getting error "Error converting data type varchar to numeric"

Im getting an error when running a procedure that includes this code.
I need to select from a dynamic column name and save the result in a variable, but seem to be having trouble with the values being fed to sp_executesql
DECLARE @retval AS DECIMAL(12,2)
DECLARE @MonthVal VARCHAR(20), @SpreadKeyVal INT
DECLARE @sqlcmd AS NVARCHAR(150)
DECLARE @paramdef NVARCHAR(150)
SET @MonthVal = 'Month' + CAST(@MonthNumber AS VARCHAR(2) );
SET @SpreadKeyVal = @SpreadKey; --CAST(@SpreadKey AS VARCHAR(10) );
SET @sqlcmd = N' SELECT @retvalout = @MonthVal FROM dbo.CourseSpread WHERE CourseSpreadId = @SpreadKeyVal';
SET @paramdef = N'@MonthVal VARCHAR(20), @SpreadKeyVal INT, @retvalout DECIMAL(12,2) OUTPUT'
--default
SET @retval = 0.0;
EXECUTE sys.sp_executesql @sqlcmd,@paramdef, @MonthVal = 'Month4',@SpreadKeyVal = 1, @retvalout = @retval OUTPUT;
SELECT @retval
DECLARE @return_value DECIMAL(12,2)
EXEC @return_value = [dbo].[GetSpreadValueByMonthNumber]
@SpreadKey = 1,
@MonthNumber = 4
SELECT 'Return Value' = @return_value
Msg 8114, Level 16, State 5, Line 1
Error converting data type varchar to numeric.

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:

This is so very, very wrong! A column is an attribute of an entity. The idea that you are so screwed up that you have no idea if you want
the shoe size, the phone number or something else at run time of this entity.
In Software Engineering we have a principle called cohesion that says a model should do one and only one task, have one and only one entry point, and one and only one exit point.
Hey, on a scale from 1 to 10, what color is your favorite letter of the alphabet? Yes, your mindset is that level of sillyity and absurdity.
Do you know that SQL is a declarative language? This family of languages does not use local variables!
Now think about “month_val” and what it means. A month is a temporal unit of measurement, so this is as silly as saying “liter_val” in your code. Why did you use “sp_” on a procedure? It has special meaning in T-SQL.
Think about how silly this is:
SET @month_val = 'Month' + CAST(@month_nbr AS VARCHAR(2));
We do not do display formatting in a query. This is a violation of at the tiered architecture principle. We have a presentation layer. But more than that, the INTERVAL temporal data type is a {year-month} and never just a month. This is fundamental.
We need to see the DDL so we can re-write this mess. Want to fix it or not?
