Form with dynamic Column Names

Hello,
I am using "Form with report on table" and I would like to make use of dynamic column names labels that are derived from another table (sql). I am stuck on how to do this, any advice?

Hi FourEyes;
Try using this.
Select Col1, Col2, Col3
into :P1_Field1, :P1_Field2, :P1_Field3

Difficult to achive the report layout with dynamic column names

I have a report layout as below.
So here the column names are dynamic.And each fixed row group has different calculations. I have a date parameter. If I select July 2013, then I need to show data from July 2012 to July 2013 with Columns(Jul-12, Aug-12...Jul-13). How to achive below layout
with dynamic columns?

Hi Sarayu_CM,
According to your description, you want to filter the records of prior year based on only one parameter selection. Right?
In this scenario, we can create two parameters. The first one is for user to select. The second parameter is based on the first parameter selection. We don't need to specify Available Values for the second parameter, but we should use expression to specify
Default Values based on the first parameter selection. Use the expression below:
=DateAdd("m",-12,FormatDateTime(Parameters!param1.Value))
Then we just need to apply a filter on the matrix/dataset to get the records which the date is between values in these two parameters.
If you have any question, please feel free to ask.

Dynamic forms using dynamic column names

I have a table with columns such as level_1, level_2, etc.
until level_11 and I have another table with level_id and
description, i.e. for level with id = 1 the description could be
'Crawl.' Id 2 could be 'Walk' etc.
I'm trying to make a checklist so people can mark when
they've done things on the checklist, and then upload those values
to the appropriate tables to store the information so it's all
still there when they go back to check off a new skill.
I can't figure out how to make the column names in the form
dynamic.
I've played around with the formatting and still can't quite
get it. I've tried evaluate(queryname.level_#level_id#),
queryname.label, a bunch of other ones, and I can't seem to get it
to work.
Thanks for the help!

Get to know CF's structure / array notation. This comes in
very handy when dealing with queries and form fields.
- Form.myFieldName can also be referenced by
Form["myFieldName"]
- MyQuery.myField can also be referenced by
MyQuery["myField"][rowNumber]
Anything in the above example surrounded by quotation makes
can be made dynamic by just adding in a cf variable surrounded by
pound signs:
get_dealer_completion["level_#level_id#"][1]

Materialized view with dynamic column names !

hello,
i need some help , i'm trying ( i got no where so far :) ) to create a materialized
view that has dynamic field name values , so every time the view is refreshed
the fields are renamed.
i have been asked to create a decade summary view and to assign year values to field names,the years should be table columns ( not rows !? ) and thus i should reflect this fact to the column names.
i know its a wierd request but is there anway to do it ?
i dunno about it at least,
Thanks !

...or you could define the materialised view neutrally e.g. with columns like YEAR1, YEAR2 etc.
Then create a dynamically-defined view on top of this view, after it's refreshed, using the relevant years as column names. SELECT year1 AS "1991", year2 AS "1992" etc.
I still don't see how anybody is going to use these views as they won't know what the "year" columns are called.
And if the same materialised view is going to have different sets of data each time it's refreshed i.e. different sets of years, are you re-defining the selection criteria each time? If so, why not just define separate views?
It's a weird world out there...

How to change recordset bahaviour to accept dynamic column names in the where clause

Hi
im using php-mysql and i make a recordset and i want to make the column names in the where clause to be dynamic like
"select id,name from mytable where $tablename-$myvar";
but when i do this my i break the recordset and it disappear
and when i use variables from advanced recordset it only dynamic for the value of the column not for the column name
and when i write the column name to dynamic as above by hand it truns a red exclamation mark on the server behaviour panel
so i think the only way is to change the recordset behaviour is it? if so How to make it accept dynamic column names?
thanks in advance.

As bregent has already explained to you, customizing the recordset code will result in Dreamweaver no longer recognizing the server behavior. This isn't a problem, but it does mean that you need to lay out your dynamic text with the Bindings panel before making any changes. Once you have changed the recordset code, the Bindings panel will no longer recognize the recordset fields.
Using a variable to choose a column name is quite simple, but you need to take some security measures to ensure that the value passed through the query string isn't attempting SQL injection. An effective way of doing this is to create an array of acceptable column names, and check that the value matches.
// create array of acceptable values
$valid = array('column_name1', 'column_name2', 'column_name3');
// if the query string contains an acceptable column name, use it
if (isset($_GET['colname']) && in_array($_GET['colname'], $valid)) {
$col = $GET['colname'];
} else {
// set a default value if the submitted one was invalid
$col = 'column_name1'
You can then use $col directly in the SQL query.

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:

>> 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 <<
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?

Importing From Flat File with Dynamic Columns

HI
I am using ssis 2008,i have folder in which I have Four(4) “.txt” files each file will have 2 columns(ID, NAME). I loaded 4
files in one destination, but today I receive one more “.txt” file here we have 3 columns (ID, NAME, JOB) how can I get a message new column will receive in source. And how can I create in extra column in my destination table dynamically …please help me

Hi Sasidhar,
You need a Script Task to read the names and number of columns in the first row of the flat file each time and store it in a variable, then create a staging table dynamically based on this variable and modify the destination table definition if one ore more
new columns need to be added, and then use the staging table to load the destination table. I am afraid there is no available working script for your scenario, and you need some .NET coding experience to achieve your goal. Here is an example you can refer

How to create a form with two column headings

I have a business request to create a data form to handle multi year data by month. This will require creating a form with two column headings - with the first row be Year and second row be month, and data entry will begin in the third row and down.
I can do multiple row headings in the layout design, but somehow can not get it to work for multiple column headings.
Thanks in advance

If you're in the "Layout" tab, simply pull the "Years" dimension and the "Period" dimension into the Column section. Planning can be a little picky about where you "drop" the dimension as you're dragging and dropping it. Drop it in the cell directly under the letter name of the column. Other than that, there's not much to it.
Hopefully this helped,

Dynamic Column name in a Cursor

Hello there,
How can I access data in cursor's field with dynamic fields names, more illustration follows:
My table has columns named as C1,C2,C3 so on
defined a cursor cursor_name on that table,
I need to access the fields by a loop like this:
OPEN cursor_name;
Fetch cursor_name into rec;
for i in 1 .. 10 loop
if rec.ci = 1Then
end if;
end loop
close cursor_name;
where rec,ci represents the name of the cursor fields, so that I loop over them,
how can I implement such an idea,
thanks in advance
regards

Thanks Bily, and user10715047,
actually the reason behind the need of such an approach, is as following:
assume that I have table of set of logical conditions, " LOGICAL CONDITIONS" has three columns: ID, Condition_name and the logical_condition, example:
1, c1, x = 1
5, c2, y = 2
10, c3, p = 3 where ID is just a sequence to identify the records from each other "primary key"
assume that I need to provide the possible combination of the result of applying each of the conditions, for example :
if c1 = 1 ,c2= 0 and c3= 1 then my result must be 1 ' This according some predefined rulesso that I created table which contains all the possible logical conditions, ( as the max number of logical conditions are known)
defined as follows : combination( combination_ID, c1, c2, c3, c4, ....cmax, result)
sample record:
combination_ID, c1, c2, c3, .. c max, result
100, 1, 0, 1, ....., 1, 1in the PL/SQL procedure, I would get all the needed combination, into a cursor, then to optimized the code, I need to access the fields ( which is the Ci) in a loop
for i in 1..3 loop
if cursor_rec.ci = 1 then
Action
end if;
end loop;the dynamic name I meant in my first post was this : cursor_rec.ci ,
so that I can access the cursor's fields without the need to name them one by one, as there could be long sequence of conditions to be checked.
hope that I made the idea clearer, Any suggestions, please !
anyway I will give the DBMS_SQL cursors a shot , try if I can use to implement the purpose,
as I know similar dynamical variable names, is available in Java,
Regards,

Dynamic column name sql?

I need to do a select statement using dynamic column names. Can it be done WITHOUT building a string to execute the sql?
In other words, I want to use a variable name in the SELECT part of a statement.
Thanks

Properly done, there shouldn't be a great difference in the performance of static and dynamic SQL. Of course, dynamic SQL is a whole lot more complicated to get right. It's also rather at odds with your requirement that column names get passed in dynamically-- if you don't know what columns you're going to select at compile time, you can't use static SQL.
That said, there are a handful of tricks around using Oracle's built-in XML processing functionality to simulate dynamic SQL. This is almost certainly less efficient than doing dynamic SQL in your case, and a whole lot more complicated, but it's technically not dynamic SQL.
The proper response, though, is almost certainly to either
1) figure out how to design the application so that column names need not be passed in at runtime or
2) use dynamic SQL.
If at all possible, option 1 is generally preferable. While there are situations where dynamic SQL is necessary, those tend to be rather rare.

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,
[9658_BoardManagementUsername] as BoardManagementUsername, [9659_BoardManagementPassword] as BoardManagementPassword,
[9660_BoardManagementVirtualAddress] as BoardManagementVirtualAddress, [9661_BoardManagementTelnetLoginPrompt] as
MANAGEMENTTELNETLOGINPROMPT, [9662_BoardManagementTelnetPasswordPrompt] as MANAGEMENTTELNETPASSPROMPT,
[9663_BoardManagementTelnetCommandPrompt] as MANAGEMENTTELNETCOMMANDPROMPT FROM Boards)performing a select * from this view in sqlserver works and show the short column names
this is the error i'm getting for performing a select * from v_boards@sqlserver_dblink
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Microsoft][SQL Native Client][SQL Server]Invalid column name 'BoardManagementTelnetLoginProm'. {42S22,NativeErr = 207}[Microsoft]

ORA-02063: preceding 2 lines from sqlserver_dblinkI also tried replacing the * with specific column names but it fails on the columns that have a long name (it doesn't recognize the short names from the view)
what am I doing wrong?

Export with dynamic file name

Hi everyone.
I want to know how export oracle tables with dynamic file name on windows XP platform.
bye.

You'd have to generate the export command-line or par file using a script -- Windows or SQL !
It would be easy to use SQL to generate the script.
So you could have a BATch file that
a. Calls the SQL to generate the export command-line or parfile
b. Executes the export
even possibly run in a loop.

Is it possible to create a Synonym with different column names

Hi,
I want to create a Synonym with different columns names (Columns not in original table) . I am not sure if this can be done . Any suggessions...
Thanks in advance....

Synonyms are not limited to tables. Accroding to the SQL Reference, a synonym is:
an alternative name for a table, view, sequence, procedure, stored function, package, materialized view, Java class schema object, user-defined object type, or another synonym.
In fact, synonyms are not even validated until they are used:
SQL> create synonym my_synonym for table_which_does_not_exist;
Synonym created
SQL> select * from my_synonym;
select * from my_synonym
ORA-00980: synonym translation is no longer valid

,CONTROLERECEPTI VARCHAR2(01)
,DATEDEPEREMPTIO VARCHAR2(8)
,CONTROLEPROCHAI VARCHAR2(1)
Thanks

Well, you can't do it. ORA-957 is one of those irrevocable errors for which the solution is to remove the duplicate name from the SQL statement.
But, anyway, why do you want to do this? I would guess there's no performance benefit from having the same column indexed twice (of course it's impossible to test this, so it's just my opinion).

How To Create Table View With Same Column name But Different Table?

I have the problem to create a tableview with same column name but in different table.
