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]

With a PDF Dynamic form using show/hide actions, how to ensure that when the completed form is saved, closed and re-opened, the form still show the fields as before it was closed?

With a PDF Dynamic form using show/hide actions, how to ensure that when the completed form is saved, closed and re-opened, the form still show the fields as before it was closed?
I have developed a form with fields hidden by default, that become visible based on box ticked or radio button selections.
My problem is that, when I close the form and re-open it, it comes back to it's default presentation, regardless of the information already recorded in the form (including in the now hidden fields.
How to correct that
Thanks in advance for any hint you can provide.

I've had the same problem. This solved it...
Go to the "Form properties..." in the File-menu. Select "Run-time" to the left and in the box "Scripting" Preserve scripting changes to form when saved: choose Automatically (Script-based state changes are saved locally in an insecure fashion. This option cannot be used for certified forms).

How to create a MD form using dynamic page ?

Rahul and Sharmila,
You have answered several of my queries earlier and I am thankful for them.
I have been trying to creating a MD form using dynamic page and I haven't fiqured it out. I need help. You both advised me on creating a simple form using dynamic page. The complexity changes drastically when I have to create a MD form. Has no body ever tried to create a MD form with dynamic page?
I haven't heard from you anything either. I am stuck with this and I need help urgently. Would you kindly tell me if this is possible and how ? Otherwise, I will stop crying for help on this.
Thanks for your kind attention.

Multi Row Selector using Generic Column Names (parse query at runtime only)

Hi,
I created a tabular report which had a multi row select in it - got the deleting working fine.
Am now creating a second tabular report, but because of the SQL:
select
"ID",
"ID" ID_DISPLAY,
"RESNUMBER",
"RESDESCRIPTION",
decode(RESTYPE,'R','Right Party','W','Wrong Party'),
decode(DMCFLAG,'Y','Yes','N','No'),
decode(SALEFLAG,'Y','Yes','N','No')
from "CALL_RESULTS"
I have to select the option Use Generic Column Names (parse query at runtime only) otherwise I cannot save the form.
My problem is I am now unable to add a multi row selector to the tabular form. If I do and run the form I get the following error - failed to parse SQL query: ORA-00904: "COL11": invalid identifier. Also when I go back and edit the form the multi row selector has been removed.
Can anyone tell me why I can't add a row selector like I previously could?
Regards
Simon

Arie,
I added aliases and to the decode columns, and I can now add a row selector to the form without any problems.
Thank you very much for your help.

APEX 4.0 "Use Generic Column Names" not working

Hi,
I have a report which is a SQL query (PL/SQL function body returning SQL query) in APEX 4.0. For this region i have selected the option "Use Generic Column Names (parse query at run time only)".
For some reason when I run the page the browser just shows the error "The requested URL /apex/f was not found on this server". This happens only for the region type "SQL query (PL/SQL function body returning SQL query)" . If I choose the report region as SQL query and select the option "Use Generic Column Names (parse query at run time only)" That works fine. This happens only in APEX 4. Is it an apex 4 bug or am I missing something?
Thanks
Sashika.

Hi,
Just managed to get it running. The Apex 4.0 SQL query (PL/SQL function returning SQL) works just fine. I had a small error in the query itself. In the PL/SQL function I had a referenced page item whose value in the initial run is set to null which is making the fuzz. Just adding an NVL resolved the problem.

How to use the column names generated from Dynamic SQL

Hi,
I have a problem with Dynamic SQL.
I have written an SQL which will dynamically generate the Select statement with from and where clause in it.
But that select statement when executed will get me hundreds of rows and i want to insert each row separately into one more table.
For that i have used a ref cursor to open and insert the table.
In the select list the column names will also be as follows: COLUMN1, COLUMN2, COLUMN3,....COLUMNn
Please find below the sample code:
TYPE ref_csr IS REF CURSOR;
insert_csr ref_csr;
v_select VARCHAR2 (4000) := NULL;
v_table VARCHAR2 (4000) := NULL;
v_where VARCHAR2 (4000) := NULL;
v_ins_tab VARCHAR2 (4000) := NULL;
v_insert VARCHAR2 (4000) := NULL;
v_ins_query VARCHAR2 (4000) := NULL;
OPEN insert_csr FOR CASE
WHEN v_where IS NOT NULL
THEN 'SELECT '
|| v_select
|| ' FROM '
|| v_table
|| v_where
|| ';'
ELSE 'SELECT ' || v_select || ' FROM ' || v_table || ';'
END;
LOOP
v_ins_query :=
'INSERT INTO '
|| v_ins_tab

How to Create Dynamic form using table data

Dear All,
I have one Table called PRODUCT_MASTER where product details are stored. Say product A,B,C,D are stored in the table. Another table called SUB_PRODUCT_MASTER, which contains sub product details.Say A1,A1,B1,B2, B3,C1, C2, C3, D1,D2,D3.
Now, I want to create a dynamic form based on product,sub product. for a whole month. For better under standing here is the format.
PRODUCT A B C D
SUB_PROD A1 A2 B1 B2 B3 C1 C2 C3 D1 D2 D3
Days
1 x x x x x x x x
2
3
4
5
6
7
Now whenever I add one row in the PRODUCT)MASTER table and SUB_PRODUCT_MASTER table, Form should add one column in the form automatically. e.g. If I add Product E with two Sub product E1 and E2 then form should add ptoduct E column in the form with sub products E1 and E2 as per above format. Here days are fixed to 31. This forms should accept product wise daily despatch entry. For
storing despatch entry another table is created.
Please help to create this type od forms.

Transpose Distinct Date and Use as Column name

All,
I am trying to transpose a distinct date and use it as a column name and list the data below it. My version of Oracle does not have the pivot function. Plus I am having trouble with figuring out how to alter the table name to the distinct date. Can someone provide me with logic that will dynamically take the current format (see below) and transpose it to the needed format (see below)?
Current format:
WEEK_END_DATE     RD     STORE_NUMBER     RANK
09-19-2009     R0011     00505     6
09-19-2009     R0028     00097     97
09-19-2009     R0057     01801     72
09-19-2009     R0061     04775     72
09-19-2009     R0068     03920     66
09-26-2009     R0011     00505     8
09-26-2009     R0028     00097     50

09-26-2009     R0068     03920     1
nth date
The format I need:
RD     STORE_NUMBER     09-19-2009 09-26-2009 nth date....
R0011     00505     6 8

R0057     01801     72 120
R0061     04775     72 30
R0068     03920     66 1

I apprreciate your help. I have tried to implement the dynamic pivot logic. I can create the correct case statement and change the column name to the name I need.
However, when I try to use @@dynamic_pivot.sql I get the following error:

and @@dynamic_pivot.sql
and @@c:\dynamic_pivot_subscript.sql
I don't have direct access to the database. I have to run my queries from toad. When I cut and paste the generated case statements, It works. I am just not able to dynamiclly insert those case statements into a select. Do you have any suggestion?

Convert dynamic form to dynamic input form

Hi All,
I am using Jdeveloper 11.1.2.4.
As a part of a requirement, I have created a dynamic form built out of a read only view object.
On a user event (button press), I want to convert the form into an input form to allow the user to make suitable change to data and save to the database.
At this stage I have programmatic access to the table name which is being used to create the dynamic form.
Please suggest on how to convert the dynamic form into input form.
Best Regards,
Ankit Gupta

<cfupdate> process data from the form scope. You are
not putting your
role datum into the form scope. You need to scope the
variable in your
cfset(s).
<cfset form.roleColumn = form.role=>
But I am not sure this would work well. It is probably better
if you
write your own SQL. <cfinsert> and <cfupdate> are
for very basic
database operations. Once you start putting other processing
requirements in, such as this, they quickly become
inadequate.
Try replacing your <cfupdate> with a <cfquery>
tag something like this.
<cfquery datasource="my_DSN">
UPDATE my_table
SET lastName = '#form.lastName#',
firstName = '#form.firstName#',
#form.role# = true
WHERE key = value
</cfquery>
I made my best guesses at how this SQL would look based on
the examples
you have provided. You'll have to finish it off based on your
actual
requirements.

How to Select data using same column name from 3 remote database

Hi,
Can anyone help me on how to get data with same column names from 3 remote database and a single alias.
Ex.
SELECT *
a.name, b.status, SUM(b.qty) qantity, MAX(b.date) date_as_of
FROM
*((table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3)a,*
*(table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3)b)*
WHERE b.dept = 'finance'
AND a.position = 'admin'
AND a.latest = 'Y' AND (b.status <> 'TRM') AND b.qty > 0;
GROUP BY a.name, b.status ;
NOTE: the bold statements is just an example of what I want to do but I always gets an error beacause of ambiguous columns.
Thanks in advnce. :)

Each object must be uniquely identified. So you cannot do this:
select * from (table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) a3 objects cannot share the same alias. Example:
SQL> select * from (dual, dual) d;
select * from (dual, dual) d
ERROR at line 1:
ORA-00907: missing right parenthesisYou need to combine the objects - using a join or union or similar. So it will need to be done as follows:
SQL> select * from (select * from dual d1, dual d2) d;
select * from (select * from dual d1, dual d2) d
ERROR at line 1:
ORA-00918: column ambiguously definedHowever, we need to have unique column names in a SQL projection - so the join of the tables need to project a unique set of columns. Thus:
SQL> select * from (select d1.dummy as dummy1, d2.dummy as dummy2 from dual d1, dual d2) d;
DUM DUM
X X
SQL> I suggest that you look closely at what scope is and how it applies in the SQL language - and ignore whether the objects referenced are local or remote as it has no impact to fundamentals of scope resolution.

Database Querry error when using # in column name

there a way to update these fields with the Database tools?

Delete command in SQLPLUS by use wrong column name command

Assume I have three table T1,T2 and T3 shown as follow...
sql> desc T1 ;
cusid number
name varchar2(50)
sql> select * from T1;
cusid name
1) 101 TEST1
2) 102 TEST2
3) 103 TEST3
4) 104 TEST4
sql>desc T2;
ref_cusid number
sql>select * from T2
cusid
1) 103
if I want to delete account in T1 that deleted account is in T2.
I must use query1 , it will work
query1::>
delete from T1 where cusid in (select ref_cusid from T2);
but if i type wrong by this command
query2::>
delete from T1 where cusid in (select cusid from T2);
in query 2,it should be have warning message because field cusid is not in T2.Right ? But it will delete all account in table T1.
compare query2 with query 3,
query3::>
delete from T1 where cusid in (select field_test from T2);
it will show warning message like 'ORA-00904: "FIELD_TEST": invalid identifier'
I noticed that in query2 and query3 , Different Thing is query 2 wrong column name in T2 has same name as column in T1. I wonder why it is.

I doubt very much if this is really what you did:
sql>desc T2;
ref_cusid number
sql>select * from T2
cusid
1) 103The desc command shows a column name ref_cusid. The select command shows a column title cusid, not ref_cusid.
You start by saying that you have 3 tables, without doing anything with T3. Are you sure you you haven't mixed up a copy and paste somewhere?

How to use get column name.vi in SQL toolkit 2.0?

Error 4101 Description:
Execute SQL - The connection, statement, or query handle you provided is not valid.
I don't just used the toolkit in a while,now, I am developing a irrigation system. For the table field names defined by users,column names must be known before any select operations. Do you have any other good idea about drawing out the columnname parameters?
As you know, a valid DSN and table have been also available. The database I used is Access. The bad thing to me is that there is no any text information gotten. And I think, it may be some problems in connection way which I don't find out.
Really appreciated by your reply.
Could you give me some example in the aspect?
Thank you again.
