Why only one column?

Hi,I use a jTable to diaplay dynamic sql. But I find only a column displayed.In fact ,I have three column . I don't know what happens. If you know or you have the same problem, please let me know. Thanks in advance.

This is an old story, in Oracle 7 that was the first data type to store binary and there was restriction. But then after that Oracle has added several new data type to store binary or big long text such as CLOB/BLOB. You should avoid using LONG RAW.

Set filter for only one column in tableview

Hi
i am using in MVC a htmlb:tableview with filter in only one column of 8.
This is all working fine, except that the user can enter a searchsting in the filterfield for all columns, but in handle_event (of the controller) ; i only react to a text in the filterfield of column 4 and ignore all other filtertext , which were maybe entered in the other columns.
My question:
how can i enter the filter only for one column, in a way that the user cannot enter any text in the filterfield of the other columns, only in column 4 ?
my view:
<htmlb:tableView id             = "requirements"
                 table          = "//model/pdst_reqs"
                 filter         = "APPLICATION"
                 keyColumn       = "EXTID"
                 iterator        = "<%=model%>"
                 footerVisible   = "FALSE"
                 encode          = "TRUE"
                 visibleRowCount = "<%=model->rowcount%>"
                 width           = "100%"/>

You can disbale the Filter for the particular column by setting the DISABLE_FILTER in the Iterator method IF_HTMLB_TABLEVIEW_ITERATOR~GET_COLUMN_DEFINITIONS. Here is the sample code
method IF_HTMLB_TABLEVIEW_ITERATOR~GET_COLUMN_DEFINITIONS .
CLEAR p_column_definitions.
CLEAR p_overwrites.
data tv_column TYPE TABLEVIEWCONTROL.
tv_column-COLUMNNAME          = 'FLDATE'.
tv_column-SORT                = 'X'.
tv_column-EDIT                = 'X'.
tv_column-ONCELLCLICK         = 'MyCellClick1'.
tv_column-title               = 'Date '.
APPEND tv_column TO p_column_definitions.
CLEAR tv_column.
tv_column-COLUMNNAME          = 'PRICE'.
tv_column-horizontalAlignment = 'right'.
tv_column-verticalAlignment   = 'middle'.
tv_column-ONCELLCLICK         = 'MyCellClick2'.
tv_column-title               = 'Currency'.
tv_column-EDIT                = 'X'.
tv_column-DISABLE_FILTER      = 'X'.    " <-------Like this
APPEND tv_column TO p_column_definitions.
endmethod.
Hope this will solve your problem.

Access for update only one column in table?

Hi all,
My need is to grant access for update only one column c1 in table t1.
I guess I should use view, could you please give me some example? Maybe other ideas?

Hi,
You can grant privileges on individual columns.
GRANT   UPDATE (c1)
ON      t1
TO      grantee_name;Look up GRANT in the SQL language manual. Annoyingly, in recent editions of the manual, GRANT is not indexed, but it's in alphabetic order with all the other statements:
http://docs.oracle.com/cd/E11882_01/server.112/e26088/statements_9013.htm#i2155015

EA2: Code is generated for only one column with Domain check constraint.

I created a Domain with a Value List (Y or N - Yes or No) and used that domain for two columns in the same table. But for only one column (the last one) the check appears in the generated DDL.
After I enabled the "Use Domain Constraints" both checks appear in the DDL, but one as an inline check constraint and one as an "Alter table add contraint.."
Once I changed the naming Template for the check constraint, both constraints are generated as an Alter table clause. The inline check constraint is only generated when the name of the constraint (according to the template) is too long. It would be nice if I could choose if I want an inline or a separate check constraint definition.

How to make only one column non reorderble

I want to make only one column (Column 0) of my JTable non reorderble.
I also want to make the same column non resizable and I want to give it a specific size.
Please help me on this?

I have implemented a RowHeaderTable class which displays 1, 2, 3, ... in the first column. The column is in the scrollpane's RowHeaderView, so it is not resizable nor reorderable. But its width can be set in your code. Maybe this is what you need.
Use the class the same way you use a JTable, except 3 added methods:
getScrollPane();
setMinRows(int r);
setRowHeaderWidth(int w);
Note: The table works perfectly in skinless L&F, such as the default java L&F. It looks ugly in Liquid L&F because I don't know how to steal column header's UI to use on a JList. If someone can help me on this one, I thank you in advance.

Copy only one column of the workbook1 and paste it in another workbook 2

Hello Rishi. Please help me with this how to copy only one column C of the workbook1 and paste it in another workbook 2 in Column D so that When user execute workbook1 . and then execute workbook2 . Column D is automatically populated in Workbook2 based on the data in Column C in workbook 1
Please help
Thanks
Soniya

Hi Soniya
As I mentioned earlier, I haven't come across a situation of copying data from one workbook to another. However, for doing some dynamic modifications within the different sheets of the same workbook, you can refer to the following thread:
Comparing two queries with VBA macro
Thanks,

Only one column was record on Trigger

Dear Experts,
I've created SQL Trigger, it has five column, but only one column was recorded when Trigger's fired, another filled by NULL value
please your valuable suggestion & helps
thank you
warmest regards

Triggers are fired by INSERT not matter how many rows it will generate and it is perfectly possible to have NULLs if columns allow it..
If you want to prevent from entering NULLs, please examine inserted virtual table to filter out the data which contains NULLs.

How do I group by only one column in a SELECT statement?

Hi everyone,
Here is my novice question:
I would like to run a query where I select (display) several columns from my table, yet group (categorize) by one of these columns.
For example:
SELECT A, B, COUNT(A)
FROM TableX
GROUP BY A
I realize now that this is not valid. My first question is why? Doesn't it make sense that you would want to group by only one of the columns? To me, it seems natural that you would most often want to categorize by one attribute, which is why it seems odd that this is not valid. I realize that I can remove column B, but I do want to display that info. I could also change the last statement to GROUP BY A, B to avoid errors, but this will also not display what I am looking for.
In addition to understanding why Oracle is set up this way, I guess I also need to know how I can legally accomplish this query, grouping by A but also displaying the values of B.
Thank you very much for your help!
Holly

Hi everyone,
Thank you for your responses... very interesting and useful. Since I came across inline views in my reading, I tried the approach recommended by g feng, although I am eager to try the other approaches too.
I ended up using an inner join simply to get more descriptive info. on the column that was being counted. With Y representing this second table, Y.B being the column containing the descriptive info., and A being the common key between X and Y, here is the simple code I came up with.
SELECT Y.B, V.*
FROM Y,
SELECT A AV, COUNT (*)
FROM X
GROUP BY A
) V
WHERE V.AV = Y.A
Does this seem correct... anything I need to watch out for?
Thanks again to everyone for your help!!

Why only one public class in a source file?

why we have to write only one public class in a source file?

PhHein wrote:
Because the JLS says so.It does?
From section 7.6 of the JLS (third edition):
When packages are stored in a file system (§7.2.1), the host system may choose to enforce the restriction that it is a compile-time error if a type is not found in a file under a name composed of the type name plus an extension (such as .java or .jav) if either of the following is true:* The type is referred to by code in other compilation units of the package in which the type is declared.
* The type is declared public (and therefore is potentially accessible from code in other packages).
This restriction implies that there must be at most one such type per compilation unit. This restriction makes it easy for a compiler for the Java programming language or an implementation of the Java virtual machine to find a named class within a package; for example, the source code for a public type wet.sprocket.Toad would be found in a file Toad.java in the directory wet/sprocket, and the corresponding object code would be found in the file Toad.class in the same directory.
>
To my mind, it's strongly recommending, rather than mandating, this practice. All academic of course, merely shifting the answer from "Because the JLS says so" to "Because pretty much all Java compilers say so". I don't know of any that don't enforce this, but of course, that doesn't mean they don't exist

Why only one public class in one file

why does java allows only one public class in one file?
Why can not we have two or more public classes in file?
Thank u.

Note, you can have multiple inner classes.
e.g.
public class A {
    public static class B {   }
    public class C {   }
    private class D {   }
}

Why only one channel of sound in sequences? Please someone try this quest

When I add a sequence to a sequence, I have only one channel of sound but, when I open that sequence I have 2 channels of sound.
Is it a sequence setting and if it is I see:
outputs 2
downmix 0
grouping: Stereo selected
Dual mono not selected.
I swith these around a bit but get no change.
My raw footage say "2 Mono" from my Sony DSR PD-150 at 16 bit, 48 khz.
I usuall use one channel for camera sound and 2nd channel for mic.

the number of audio channels that your nested sequence will contain is the same as the number of audio outputs you have selected for that sequence ...
for example, if you create a sequence with 10 tracks of audio, but have only set the sequence to have 2 audio outputs, then when you nest that sequence the nest will have only 2 tracks of audio ... change the audio outputs to 4, or 6, or 8, or 10 etc regardless of how many tracks you actually use, and the sequence, when nested, will have the same number of audio tracks as the sequence has audio outputs
... ok, so that explains the relationship between audio outputs and the number of tracks of audio that a nested sequence contains
so why are you getting only one channel of sound when you edit it in to another sequence? my guess is that you are only patching 1 channel ... load the source sequence into the viewer (drag and drop), now check in the patch bay area at the left of the timeline window to make sure that your a1 to A1 and a2 to A2 connections are not broken ... and edit it in.
cheers

Distinct for only one column

Hi,
I want select only distinct column of one column while at the same time displaying the other column attributed to the selected column.
e.g. select name
from student
where name in
(select distinct name from student)
and processing_date >= '20070701'
and processing_date < '20070702'
this list all the similar rows and the distinct. Please assist. Thanks

I'm sorry, but I am still a confused. Your current query, as written, is logically equivalent to...
SELECT name, address
FROM   student
WHERE processing_date >= '20070701'
AND    processing_date < '20070702';since selecting the DISTINCT names from the same table will match on every row.
Are you looking for the DISTINCT names and addresses?
SELECT DISTINCT name, address
FROM   student
WHERE processing_date >= '20070701'
AND    processing_date < '20070702';Or are you looking for output like this?
Bill Johnson   123 Main Street
               456 West Lane
John Doe       222 Hill Stree
               888 East AvenueAgain, some sample output would be helpful.

Only one column header in delimited report ?

Hi!
Is there a way to put only one line of column header on delimited report?
(By default the Report builder puts the header in every record line...
as well the delimited_hdr = no command prompt property is not good, because puts out no header)
Thanks!
(I use RB 6i)

Hello,

Why only one recent backup to restore from?

I backup up my iPhone every day. In iTunes>Preferences>Devices, why do I only see today's backup and a backup from three months ago?

Only one backup is kept by itunes(this backup is overwritten each time you sync), except for restore backups, which are not overwritten & are kept by time & date stamp. The reason you don't see any other backups listed is because you most likely have never restored your phone. If you performed a sync before you restored from backup, your backup was overwritten & that's why your info was not replaced.
If you backup your computer, you can extract your backup from that computer backup, replace the one on your computer with this & restore from that backup. DO NOT SYNC before restoring from this backup. You will be given the option to create a backup before you restore, decline.

Why only one column?
