Selecting Column Names

Hi,
I'm using Forms6i.
I have a table 'Call_header' with columns 'CallID', 'Attach1','Attach2' and 'Attach3'.
and in my form,i've a control block with 2 text fields, one for Callid and the otherone for which i need to show lov from 'Call_Header'.
Suppose the table contains values like
Callid      Attach1        Attach2     Attach3
1           D:\test.doc
2                            D:\pull.ico
etc ....So in my form if user enter '1' for callid, for the next text item i need to show lov with values 'Attach2' and 'Attach3'.
Because in that lov i need to show the column names out of the three Attach column, whichever is null.
suppose if user entered 2 for callid the lov should have values Attach1 and Attach3
So i've written the query something like this
Select 'HCH_ATTACH_1' ColumnName from HLP_CALL_HEADER where HCH_ATTACH_1 is null and HCH_CALL_ID =:CALLID
union
Select 'HCH_ATTACH_2' from HLP_CALL_HEADER where HCH_ATTACH_2 is null and HCH_CALL_ID = :CALLID
union
Select 'HCH_ATTACH_3' from HLP_CALL_HEADER where HCH_ATTACH_3 is null and HCH_CALL_ID = :CALLID ;This is giving correct results, But is this the right way? or is there someother simple way to get that?

Hi
every way is correct if get the result.

Dynamically selecting column names in report builder ???

Dear members,
I have a requirement in which the user dynamically selects the tables column names. Like suppose take DEPT table. My query would be
select &P Report from dept;
so if the user selects DNAME then i would get the dname values and so on... This is fine but if one gives the value for the lexical parameter as DEPTNO,DNAME then i should get two columns in my report output. The select statement then becomes
select DEPTNO,DNAME Report from dept;
But i am not able to do this in report builder(6i). If i use just one value for the parameter then i get the o/p but if i use more than one (eg: DEPTNO,DNAME) then its giving an error.when i run this query through toad or sql plus then i am getting the desired o/p but wher as in report builder i am not able to get the o/p.
My report triggers are :
Before Parameter form :
:P := NULL;
After parameter Form :
function AfterPForm return boolean is
begin
IF :P = 'DNAME,DEPTNO' THEN
:P := ' DNAME,DEPTNO ' ;
ELSE
:P := NULL;
END IF;
return (TRUE);
end;
Your comments and suggestions are welcomed.
thanks

Number of columns can not be changed at run time. If your data model has three columns, lexical parameter should pass 3 values. If you have query like this in data model:
select &p_1 from table
Whatevere you have as initial value in user parameter p_1, data model captures that info.

Using dynamic column name in datagrid selectedItems

Hi
I have a datagrid loaded with 2 columns. Allowmultiselect is turned on.
Based on the values selected at run time, I get the corresponding selected column name and its values and shown it on HTML screen.
// grp is datagrid
// dgrcl is a data grid column
// selflds is an array which has 0,1,2,3 values
//selflds[0] = name,selflds[1]=age
for (var l:int=0; l<grp.columnCount; l++)
dgrcl =grp.columns[l];
selflds[l] = dgrcl.dataField;
// srhVals will have only one selected value at any point
// getting the corresponding selected column name and its value
var srhVals:String;
srhVals = String(grp.selectedItem[selflds[1]]);
I am trying to achieve the above selection instead by .selectedItems somthing like this below. By doing like this, I will get all the selected items but not only one. If i try below syntax, i get error. Any one has ideas on how to do.
srhVals = String(grp.selectedItems.selflds[1]);

Hi
I got my mistake, there should be no dot operator after selectedItems;
I got a solution - it goes like this:
for(var g:int=0;g<grp.selectedItems.length;g++)
srhVals = srhVals + String(grp.selectedItems[g][selflds[1]]);
So the complete scenario is like this:
Datagrid:
Name      Age
a               20
b               30
c               40
d               50
I am selecting b,d in UI. At run time, I get programatically the selecteditem column name as "Name", loop through the selecteditems and store the value in srhVals as b,d.
b,d will be finally shown in UI.

ResultSetMetaData.getColumnLabel(int coluN) gives column name with quote

I am using ojdbc14.jar for "Oracle Database 10g Enterprise Edition Release 10.2.0.3.0". My query is "Select 'column name' from dual". When i get column name using ResultSetMetaData.getColumnLabel(int coluN) it return column name including single quotes ie: for the above query result is 'columname'. Ideally it should not return ' (single quote).
Why do this happening?

You will have that even when you run with sqlplus.

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

How to pull only column names from a SELECT query without running it

How to pull only column names from a SELECT statement without executing it? It seems there is getMetaData() in Java to pull the column names while sql is being prepared and before it gets executed. I need to get the columns whether we run the sql or not.

Maybe something like this is what you are looking for or at least will give you some ideas.

How to select even the column names of a table?

Hello All,
Is there a way to select even the column names of a table in the select statement?
My select from a table (say X) is in a SQL* Plus script that gets invoked by application tier and displays data in the application tier window. User's can then copy the data into a spreadsheet and do their processing. However, I need to give them the column names too along with the data.
Thanks,
Chiru

If there is a middle tier that is selecting and
displaying the data, and that's what the users are
copying from, the middle tier would have to address
its presentation of the data to allow users to
include column names. If this is a common task, the
application should probably be modified to give users
the option of downloading the data in a spreadsheet
directly rather than forcing them to copy and paste
data.Thanks for the reply.
The users don't have to copy paste. The application tier has an options in the "Tools" menu item which allows them to copy the entire output to a file (in my case a txt file which is a pipe delimited). Then they have to do text to columns to get the data into each column of the spreadsheet. I could have directly called the stored procedures from the application tier and created ".csv" files and FTP'd them to the user's folders. However, I am having to go this round about because, I am not getting enough support from the LAN team in FTP'ing etc.
OK I'll think of another workaround.
Thanks,
Chiru

How to select columns in a table by their column id and not the column name

Hello,
How do you select columns from a table based on their column_id.
I have create a view
but other than Select * , i cant now select one just one column from it
the view as follow:
create view count_student as
select a.acode "acode",aname "Activity Name",count(ae.acode) "Number of student joined"
from aenrol ae, activity a
where a.acode= ae.acode
group by a.acode,aname;

The issue is that you have decided to use quoted column names. A pretty horrible idea (mostly for the reasons that you are now finding).
Re-create the view and get rid of the silly double quotes.

Selecting from a SQL Server 2005 with long column names ( 30 chars)

Hi,
I was able to set up a db link from Oracle 11.2.0.1 to SQL Server 2005 using DG4ODBC.
My problem is that some column names in the Sql Server are longer than 30 chars and trying to select them gives me the ORA-00972: identifier is too long error.
If I omit these columns the select succeeds.
I know I can create a view in the sql server and query it instead of the original table, but I was wondering if there's a way to overcome it with sql.
My select looks like this:
select "good_column_name" from sometable@sqlserver_dblink -- this works
select "good_column_name","very_long_column_name>30 chars" from sometable@sqlserver_dblink -- ORA-00972Thanks

I tried creating a view with shorter column names but selecting from the view still returns an error.
create view v_Boards as (select [9650_BoardId] as BoardId, [9651_BoardType] as BoardType, [9652_HardwareVendor] as
HardwareVendor, [9653_BoardVersion] as BoardVersion, [9654_BoardName] as BoardName, [9655_BoardDescription] as BoardDescription,
[9656_SlotNumber] as SlotNumber, [9670_SegmentId] as SegmentId, [MasterID] as MasterID, [9657_BoardHostName] as BoardHostName,

this is the error i'm getting for performing a select * from v_boards@sqlserver_dblink

Run time Column Name in the Select Statement

Hi there,
I face problem while writing sql statment for report in the Oracle reports.
The prom is I want to bound the where clause column name with the value stored in a variable e.g.

At a time the value of Column_Name is Dept then
Select * from emp
where Dept = 'XYZ' ;
At other time value of Column_Name is City then
Select * from emp
where City = 'XYZ' ;
Waiting for the response .

Hi,
U can use lexical parameters for the solutions.U must be aware of it, but still i describe how to work it out.
1)In your datamodel in object navigator create a parameter under User parameter node.Name the parameter, for eg. p_clause.
set data type of parameter to character.
2)write a select query eg.
select * from emp &p_clause; --(THIS IS THE PARAMETER WE CREATED ABOVE)
3)Now run your report
Now in your parameter form pass the value for p_clause parameter.
eg: where name='JACK';
or
where city='NEWYORK';
or where deptno=10;
But do it in steps as above mentioned.
Do tell me if it works or not via mail on [email protected]
Enjoy.......

Item value as column name in select

Hi,
I have a problem with selecting the columns in the query using items. For example: I have a query:
select column_a from table; or select column_b from table;
and I want to do something like this:
- any item in which I choose the column name
- query: select column_from_item from tale
Is it possible?
My apex version: 4.0.2.00.07
My oracle db version: oracle 11g

Unfortunately, it does not work. For example:
I have a table book (title, themes ...), which is eight rows. When I create a static list of items containing the column names (display name and returns the name) and a report based on select according to your design(select :P5_select from table;), you get eight records in the name of the column.
item: select list -> static list -> display value: Title, return value: Title, name: P1_title
select :P1_title from books;
result which i get:
Title
Title
Title
Title
