Af:table with any predefined column (dynamicaly build)

I want to create a table but i don't know the number and name of the column.
The user select the object attribute he wants to display in the table and the table his displayed dynamicaly with user selected object attributes.
How to do this with af:table or backing bean ?

A af:table, a Data Table is generated with the Create DataTable Wizard.
In the Create DataTable Wizard either the number of coumns are required to be specified, or a data table may be created by binding a managed bean method which returns a List, ResultSet or an array.
The number and name of columns are required to bind a data table with a List, result set or array and generate a data table.
Generating a JSF Data Table section explains generating a data table from a method which returns a List.
http://www.oracle.com/technology/pub/articles/vohra_hibernate.html
The SQL query which generates the result set may be different. The number of columns in the result set are required to be the same.

Combining two tables without any distinct columns between them

Folks,

Hi sidy2j,
According to your description, we need to verify your table structures, and the actual results which you want to get from your tables. Please post more information for analysis.
Assume, if you want to a one to one record mapping between two tables without any common column between them for joining, you can refer to the following scripts to implement your requirement. For more information, see:
http://sqlhints.com/2013/09/07/joining-two-tables-without-any-common-column-between-them-sql-server/
If you want to match every row in the first table with every row in the second table, you can refer to the following detail.

Difference between an XMLType table and a table with an XMLType column?

Hi all,
Still trying to get my mind around all this XML stuff.
Can someone concisely explain the difference between:
create table this_is_xmltype_tab of xmltype;and
create table this_is_tab_w_xmltpe_col(id number, document xmltype);What are the relative advantages and disadvantages of each approach? How do they really differ?
Thanks,
-Mark

There is another pointer Mark, that I realized when I was thinking about the differences...
If you would look up in the manual regarding "xdb:annotations" you would learn about a method using an XML Schema to generate out of the box your whole design in terms of physical layout and/or design principles. In my mind this should be the preferred solution if you are dealing with very complex XML Schema environments. Taking your XML Schema as your single point design layout, that during the actual implementation automatically generates and builds all your needed database objects and its physical requirements, has great advantages in points of design version management etc., but...
...it will create automatically an XMLType table (based on OR, Binary XML of "hybrid" storage principles, aka the ones that are XML Schema driven) and not AFAIK a XMLtype column structure: so as in "our" case a table with a id column and a xmltype column.
In principle you could relationally relate to this as:
+"I have created an EER diagram and a Physical diagram, I mix the content/info of those two into one diagram." "Then I _+execute+_ it in the database and the end result will be an database user/schema that has all the xxxx amount of physical objects I need, the way I want it to be...".+
...but it will be in the form of an XMLType table structure...
xdb:annotations can be used to create things like:
- enforce database/company naming conventions
- DOM validation enabled or not
- automatic IOT or BTree index creation (for instance in OR XMLType storage)
- sort search order enforced or not
- default tablenames and owners
- extra column or table property settings like for partitioning XML data
- database encoding/mapping used for SQL and binary storage
- avoid automatic creation of Oracle objects (tables/types/etc), for instance, via xdb:defaultTable="" annotations
- etc...

Importing a table with a BLOB column is taking too long

I am importing a user schema from 9i (9.2.0.6) database to 10g (10.2.1.0) database. One of the large tables (millions of records) with a BLOB column is taking too long to import (more that 24 hours). I have tried all the tricks I know to speed up the import. Here are some of the setting:
1 - set buffer to 500 Mb
2 - pre-created the table and turned off logging
3 - set indexes=N
4 - set constraints=N
5 - I have 10 online redo logs with 200 MB each
6 - Even turned off logging at the database level with disablelogging = true
It is still taking too long loading the table with the BLOB column. The BLOB field contains PDF files.
For your info:
Computer: Sun v490 with 16 CPUs, solaris 10
memory: 10 Gigabytes
SGA: 4 Gigabytes

Legatti,
I have feedback=10000. However by monitoring the import, I know that its loading average of 130 records per minute. Which is very slow considering that the table contains close to two millions records.
Thanks for your reply.

What index is suitable for a table with no unique columns and no primary key

alpha
beta
gamma
col1
col2
col3
100
1
-1
a
b
c
100
1
-2
d
e
f
101
1
-2
t
t
y
102
2
1
j
k
l
Sample data above and below is the dataype for each one of them
alpha datatype- string
beta datatype-integer
gamma datatype-integer
col1,col2,col3 are all string datatypes.
Note:columns are not unique and we would be using alpha,beta,gamma to uniquely identify a record .Now as you see my sample data this is in a table which doesnt have index .I would like to have a index created covering these columns (alpha,beta,gamma) .I
beleive that creating clustered index having covering columns will be better.
What would you recommend the index type should be here in this case.Say data volume is 1 milion records and we always use the alpha,beta,gamma columns when we filiter or query records
what index is suitable for a table with no unique columns and primary key?
col1
col2
col3
Mudassar

Many thanks for your explanation .
When I tried querying using the below query on my heap table the sql server suggested to create NON CLUSTERED INDEX INCLUDING columns ,[beta],[gamma] ,[col1]
,[col2] ,[col3]
SELECT [alpha]
,[beta]
,[gamma]
,[col1]
,[col2]
,[col3]
FROM [TEST].[dbo].[Test]
where [alpha]='10100'
My question is why it didn't suggest Clustered INDEX and chose NON clustered index ?

Cartesian of data from two tables with no matching columns

Hello,
I was wondering – what’s the best way to create a Cartesian of data from two tables with no matching columns in such a way, so that there will be only a single SQL query generated?
I am thinking about something like:
for $COUNTRY in ns0: COUNTRY ()
for $PROD in ns1:PROD()
return <Results>
<COUNTRY> {fn:data($COUNTRY/COUNTRY_NAME)} </COUNTRY>
<PROD> {fn:data($PROD/PROD_NAME)} </PROD>
</Results>
And the expected result is combination of all COUNTRY_NAMEs with all PROD_NAMEs.
What I’ve noticed when checking query plan is that DSP will execute two queries to have the results – one for COUNTRY_NAME and another one for PROD_NAME. Which in general results in not the best performance ;-)
What I’ve noticed also is that when I add something like:
where COUNTRY_NAME != PROD_NAME
everything is ok and there is only one query created (it's red in the Query plan, but still it's ok from my pov). Still it looks to me more like a workaround, not a real best approach. I may be wrong though...
So the question is – what’s the suggested approach for such queries?
Thanks,
Leszek
Edited by xnts at 11/19/2007 10:54 AM

Which in general results in not the best performanceI disagree. Only for two tables with very few rows, would a single sql statement give better performance.
Suppose there are 10,000 rows in each table - the cross-product will result in 100 million rows. Sounds like a bad idea. For this reason, DSP will not push a cross-product to a database. It will get the rows from each table in separate sql statements (retrieving only 20,000 rows) and then produce the cross-product itself.
If you want to execute sql with cross-products, you can create a sql-statement based dataservice. I recommend against doing so.

Tabular Form based on table with lots of columns - how to avoid scrollbar?

Hi everybody,
I'm an old Forms and VERY new APEX user. My problem is the following: I have to migrate a form application to APEX.
The form is based on a table with lots of columns. In Forms you can spread the data over different tab pages.
How can I realize s.th similar in APEX? I definitely don't want to use a horizontal scroll bar...
Thanks in advance
Hilke

If the primary key is created by the user themselves (which is not recommended, you should have another ID which the user sees which would be the varchar2 and keep the primary key as is, the user really shouldn't ever edit the primary key) then all you need to do is make sure that the table is not populated with a primary key in the wizard and then make sure that you cannot insert a null into your varchar primary key text field.
IF you're doing it this way I would make a validation on the page which would run off a SQL Exists validation, something along the lines of
SELECT <primary key column>
FROM <your table>
WHERE upper(<primary key column>) = upper(<text field containing user input>);
and if it already exists, fire the validation claiming that it already exists and to come up with a new primary key.
Like I said if you really should have a primary key which the database refers to each individual record itself and then have an almost pseudo-primary key that the user can use. For example in the table it would look like this:
TABLE1
table_id (this is the primary key which you should NOT change)
user_table_id (this is the pretend primary key which the user can change)
other_columns
etc
etc
hope this helps in some way

How to display a table with rows and columns?

Hi All,
I am new to IPhone development,
In my app user has to pick date from control, I had used UIDatePicker but user cannot pick year from that. so I wanted to write my own calendar view i.e A table with 6x7 cells using UITable.
code snippet or any information on this will be appreciated.
Thanks,
Vashek

I don't believe that the UITable on the iPhone supports mutiple columns. It is just a list of table cells. Each cell can have its own subset of controls (views) and I suppose this may be one way to give you what you want. But it seems like it would almost be better just to make your own table -- a view that contains the grid of subviews -- and lay that out in the parent view.
I haven't had any experience with the UIDatePicker yet, though I can see it doesn't support year ... Why not build your own custom picker? It seems that would be a lot less hassle, and maybe more intuitive for the user, than building a full calendar view, especially if what you wanted initially was a picker anyway.
Edit: I feel bad ... I didn't read through all the modes of UIDatePicker -- it does have a mode that supports year (UIDatePickerModeDate).

Query to get the data of all the columns in a table except any one column

Can anyone please tell how to write a query to get the data of all the columns in a table except one particular column..
For Example:
Let us consider the EMP table.,
From this table except the column comm all the remaining columns of the table should be listed
For this we can write a query like this..
Select empno, ename, job, mgr, sal, hiredate, deptno from emp;
Just to avoid only one column, I mentioned all the remaining ( 7 ) columns of the table in the query..
As the EMP table consists only 8 columns, it doesn't seem much difficult to mention all the columns in the query,
but if a table have 100 columns in the table, then do we have to mention all the columns in the query..?
Is there any other way of writing the query to get the required result..?
Thanks..

Your best best it to just list all the columns. Any other method will just cause more headaches and complicated code.
If you really need to list all the columns for a table because you don't want to type them, just use something like...
SQL> ed
Wrote file afiedt.buf
1 select trim(',' from sys_connect_by_path(column_name,',')) as columns
2 from (select column_name, row_number() over (order by column_id) as column_id
3        from user_tab_cols
4        where column_name not in ('COMM')
5        and   table_name = 'EMP'
6       )
7 where connect_by_isleaf = 1
8 connect by column_id = prior column_id + 1
9* start with column_id = 1
SQL> /
COLUMNS
EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,DEPTNO

Error when inserting in a table with an identity column

Hi,
I am new to Oracle SOA suite and ESB.
I have been through the Oracle training and have worked for about 2 months with the tooling.
We have a Database adabter that inserts data in 5 Tables with relations to each other.
Each table has his own not NULL Identity column.
When running/ testing the ESB service we get the error at the end of this post.
From this we learned that the Database adapter inserts the value NULL in the identity column.
We cannot find in the documentation how to get the database adabter to skip this first column and ignore it.
Is this possible within the wizard? Our impression is no
Is this possible somwhere else/
And if so How can we do this?
If anyone can help it would be greatly appreciated

Hi,
Click on the resources tab in the ESB system/ Project to see the ESB system design and all the components in it.
Click on the Database adapter that you want to edit..and make the necesary changes..
Check this link.
http://download-uk.oracle.com/docs/cd/B31017_01/core.1013/b28764/esb008.htm for "6.8.2 How to Modify Adapter Services" section.
If you are calling a database procedure which inturn makes the insert, you will have to make changes in the database and you job would be much simpler. It seems there are limitations on what you can change in the Database adapter once it is created. Please check the link for further details.
Thanks,
Rajesh

Tables with different-width columns

Whist creating a table with multiple rows and columns, I need some of the columns to be different widths on each row. I can do this easily in Word by simply selecting the cell and command-drag the vertical line at the left or right hand side.
When I do this in InDesign, the whole damn column moves. I do not want this.
Also - as in Word - I need to be able to calculate sums.
Why is none of this possible with such a powerful application like InDesign CC 2014? Seems like Microsoft Word kicks InDesign CC 2014's *** on this.

I do not want InDesign to work like Word, oh no. I just designed a 200 page book in InDesign - it was a breeze. I shudder at the thought of having to do that in Word. The table functions of the application are limited. Here's the thing, I want to be able to layout a specialised table/form with my specialised design tool and be able to specify the sizes of columns, cells and rows as I choose, and change on the fly if necessary. My screwdriver drives screws in - and back out again as I choose. I can slide an individual column divider one way but not the other. It's a bit like having an all singing-all dancing Swiss Army knife that doesn't have the corkscrew, and your out on a picnic with a nice bottle of red in your basket.
A guy from Adobe remote-shared my screen, telling me what I wanted to achieve was possible. I showed him using Word how easy it was. He tried and failed in InDesign and conceded that it was in fact not possible. He gave me a link to Adobe for a feature request!

Generating table with XML Type column while registering schema

Is it possible to generate a table with an XML Type column during schema registering. Does the "xdb:defaultTable" always create an XMLType table?

You could use the COPY feature once your second table is created:
DROP TABLE one
DROP TABLE two
CREATE TABLE one
(n NUMBER
,l LONG)
INSERT INTO one
VALUES
(1
,'123'
CREATE TABLE two
(n NUMBER
,l LONG)
COPY FROM apps/apps@dblink TO apps/apps@dblink APPEND two USING SELECT * FROM one
SELECT * FROM one
SELECT * FROM two
null
