How to dynamically list field names

Hello,
I have a DB Link to a SQL 2000 Server and can connect and retrieve using Heterogenous Servives.
Let say I issued a Select (eg., Select * from tab@remote1), how do I dynamically list each field name from the result?
Thank you.

The best way to deal with dynamic column names from a SQL result is to use a cursor describe interface.
A SQL SELECT may not select all the columns from a table. It may join tables. It may add derived and calculated columns to the result.
None of these will be seen when using the data dictionary. Also, using a remote heterogeneous data dictionary? That does not sound like a sensible approach to me.
In PL/SQL, one can create DBMS_SQL cursors. These cursors can be "described" - i.e. the describe interface for a cursor tells you what the contents are, the column names, the data types, the precision, etc.
Using DBMS_SQL allows you to describe any result set from any SELECT statememt. A far superior and accurate method than to go data dictionary hunting to determine just which column could be in a result set.

HR - dynamic selections field name and field value in the program

HI all,
I am using dynamic selections for a HR report.
I have created a view with 20 fields and added it to HR report category ___00003(All fields suppressed).
I need to check these fields in the program. But i am not able to get the field name and value in the program for dynamic selections fields.
Please let me know how to get the field names and values in the program for dynamic selections .
Thanks,
Kranthi.

You have to read the itab pnpdynse in your Program to obtain the Dynamic Selection values. This itab has a deep structure.. you can set a break point in one of the events before get pernr & in the debug mode, you will able to display the itab pnpdynse.. you can then identify how to get the values into your code..

May be a rude way .. but it works.
Add narrative view and use Java script to change the column headings based on the variables.
<script language="javascript" type="text/javascript">
var a = document.getElementById('idResultsTableParent');
var rows= a.getElementsByTagName('tr');
rows[1].cells[1].innerText ="@{Presentation Variable}";
</script>

Evaluating dynamically generatedform field names

On form submission I need to find out if check boxes exist
and have values. The field names are generated dynamically &
there could be many. Here's the code I've been messing with. I am
able to find out it the field has a value if it exists, but I can't
figure out how to combine this with isDefined("") to test for the
field's existence and avoid the "field i not defined in form"
errors.
<cfloop index="a" from="1" to="#form.numRows#">
<cfset thisname = "form." & #a# & "_Clear">

<cfset thisVal= Evaluate("form.#thisname#")>
<cfoutput> #thisname# #thisVal# </cfoutput>
</cfloop>
Thanks in advance for any help!

run a loop over your field names like: <cfloop index="x"
list="#form.fieldnames#"> then you have all of your form field
names that are defined.

How to find the field name of variable system information on SAP B1

Hi All,
I recently wanted to create a simple SQL query to list all ITEM MASTER DATE where the weight is blank. This is so i can get a list of all items with the weight information missing from the system to investigate.
It turns out the weight field within the SALES DATA tab is a system variable. When i pull the OITM table up within the query generator i can not identify where this variable name come up without guessing which can give me the wrong information.
Can someone point me into the direction on how to assisocate variable to a field name within SAP B1. This is also another problem if i wanted to display variable within Crystal report layout.
Regards

Hi Nick Dang,
Try This
SELECT T0.[ItemCode], T0.[ItemName], T0.[SalUnitMsr], T0.[SHeight1], T0.[SWidth1], T0.[SLength1], T0.[SVolume], T0.[SWeight1] FROM OITM T0 WHERE T0.[ItemCode] =[%0]

Select column_name from user_tab_cols where table_name = 'Table_Name';
Note: Table_Name should be in capital letters
In MS SQL Server it is,
SELECT Column_Name + ', '

WHERE TABLE_NAME = 'Table_Name'

How to capture the field name on a form when it's double-clicked?

Hello,
I plan to create a two field Help table that uses the thirty or so unique field names on the user form in field one. The second field is a Memo type field that contains the Help information for each field.
Once I know the field name clicked, I will probably use a query to retrieve the help information. I'm planning to use the Double-Click event so the users can double-click any field on the form to be presented the specific field related information
from the Help table.
How can I capture the name of the field that was double-clicked, so I can proceed with this project? Thank you.
Cordially,
John
Thank you, John Portland, Maine

Thank you, Hans,
How about this code:
Dim varClickedFieldName as String
varClickedFieldName = ScreenActiveControl.ControlSource
Or would you recommend other code?
Cordially,
