Row and Column Level Select Permission

Hello Friends,
I am using Oracle Oracle9i Enterprise Edition Release 9.2.0.1.0 and Windows XP. I have two questions. How to set :
1. Row Level Select Permission?
2.Column Level Select Permission?
1. I have a table having 100 records in it. I don’t want to allow all the user to see them; means, if user1, user2 and user3 are going to select * from mytable then only they can get all the rows; while other users (including sys) should not able to get all rows, they should be capable of from 11th record.
Though it can be managed by using another table, but I am just finding the other solution.
2. Likewise, if I don’t want to allow to fetch all the columns; suppose column4 is having confidential info and only be visible by user1,user2 and user3 only, not by any othr user; what should I do?
Please guide and help me.
Regards

You would need to use Virtual Private Database (VPD)/ row level security (RLS) to apply row-level security policies to the table. The DBMS_RLS package is used for this
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_rls.htm#sthref6168
Unfortunately, column-level security wasn't available in 9.2. You would need to upgrade to Oracle 10g to get that functionality. Before that, you would have to create views that selected appropriate subsets of columns and grant permissions on those views to different users.

Hi,
i have a problem like the JTable having one Method getSelectedRow() and getSelectedColumn to know the Selected row and Column but if i want to explicitly set the Selected Row and Column,then there is no such type of Methods.If anybody has any solution then i will be thankful to him/her.

Select row and column from header in jtable

hello i have a problem to select row and column from header in jtable..
can somebody give me an idea on how to write the program on it.

Hi Vicky Liu,
Thank you for your reply. I'm sorry for not clear question.
Answer for your question:
1. First value of Open is item fiels in Dataset2 and this value only for first month (january). But for other month Open value get from Close in previous month.
* I have 2 Dataset , Dataset1 is all data for show in my report. Dataset2 is only first Open for first month
2. the picture for detail of my report
Detail for Red number:
1. tb_Open -> tb_Close in previous month but first month from item field in Dataset2
espression =FormatNumber(Code.GetOpening(Fields!month.Value,First(Fields!open.Value, "Dataset2")))
2. tb_TOTAL1 group on item_part = 1
expression =FormatNumber(Sum(CDbl(Fields!budget.Value)))
3. tb_TOTAL2 group on item_part = 3 or item_part = 4
expression =FormatNumber(Sum(CDbl(Fields!budget.Value)) + ReportItems!tb_TOTAL1.Value )
4. tb_TOTAL3 group on item_part = 2
expression =FormatNumber(Sum(CDbl(Fields!budget.Value)) - ReportItems!tb_TOTAL2 .Value)
5. tb_Close -> calculate from tb_TOTAL3 - tb_Open
expression =FormatNumber(Code.GetClosing(ReportItems!tb_TOTAL3.Value,ReportItems!tb_Open.Value))
I want to calculate the value of tb_Open and tb_Close. I try to use custom code for calculate them. tb_close is correct but tb_Open is not correct that show value = 0 .
My custom code:
Dim Shared prev_close As Double
Dim Shared now_close As Double
Dim Shared now_open As Double
Public Function GetClosing(TOTAL3 as Double,NowOpening as Double)
    now_close = TOTAL3 + NowOpening
    prev_close = now_close
    Return now_close
End Function
Public Function GetOpening(Month as String,NowOpen as Double)
    If Month = "1" Then
        now_open = NowOpen
    Else
        now_open = prev_close
    End If
    Return now_open
End Function
Thanks alot for your help!

Multiple Rows and Columns selection on ALV

Hi all,
What is the best solution to allow the multiple selection or combination of selection (rows and columns) on an ALV ?
I would like to be able to select some rows and some columns and to get the result cells in order to update them.
Thanks in advance for your help.
David

Thanks Srinivas and Seela,
I forgot to precise that my ALV is dynamic, I used the method 'add_new_child_node'.
I tried the different possibilties with method attributes but I don't find the good attributes combination to allow columns selection.
I add also that I have to be able to select several no adjacent columns.
What do you think about this workaround :
Is it possible to add a line on my ALV with checkbox between the header line (with column title) and data line.
I will search using the method add_cell_variant but I don't know if it's possible with dynamic ALV.
Thanks.
David

Make Select rows and columns as read only in Table Control

Hi All,
I would like to know how to make certain cells in a Table Control as display only.
Table control should look like-(Those in bold are read only or in display mode)
Name1 Idno1 Address1
Name2 Idno2 Address2
Name3 Idno3 Address3
Name4 Idno4 Address4
(Blank row to enter name idno and address)
(Blank row to enter name idno and address)
(Blank row to enter name idno and address)
My table control should display all the above fields the way it is above of which first two colums and 4 rows should be read only,and the rest of the empty rows in the TC should be in change mode.i.e it must have provision to add new rows but not change the first two columns of existing rows.
In short I am looking at solution to hide particular no of rows and columns and not the entire column.

In the PBO of the table control loop. just write these statements
NAME and IDNO considering the fields on the screen.
and WA_TAB is the table work area being passed to the table control to display the rows.
if not WA_TAB-NAME is initial and not WA_TAB-IDNO is initial.
loop at screen.
if screen-name = 'NAME' or
 screen-name = 'IDNO'.
screen-input = 0.
modify screen.
endif.
endloop.
endif.
which means that the fields are disabled only if NAME and IDNO are not initial.

Sum calculated rows and columns

I have written a SQL report to count the number of offenses by levels of disciplinary actions. Now I want to total
the counts for the rows and columns. How do I do this? Below is my code. It produces column headings with counts. Ie.
Offense Description Level I Level II Susps Terms
2 Minor Violations 0 1
0 0
SELECT
UPPER(DESCRIPTION) as OFFENSE,
SUM(CASE
WHEN OUTCOME = 'LEVEL I'
THEN 1
ELSE 0
END) as LEVELI,
SUM(CASE
WHEN OUTCOME = 'LEVEL II'
THEN 1
ELSE 0
END) as LEVELII,
SUM(CASE
WHEN OUTCOME = 'SUSPEND'
THEN 1
ELSE 0
END) as SUSPEND,
SUM(CASE
WHEN OUTCOME = 'TERM'
THEN 1
ELSE 0
END) as TERM
FROM
PAGRDI
Where
R_DATE >= '2014-01-01' and R_DATE <= '2014-01-31'
Group by
DESCRIPTION
Order by
OFFENSE

Hi Wildcatgirl,
According to your description, you have used T-SQL to get the counts for different OUTCOME. Now you want to get the total for each OFFENSE and OUTCOME. Right?
In this scenario, since you have already get those counts with T-SQL query, so in your dataset it will have data fields below: OFFENSE, LevelI, LevelII, SUSPEND, TERM. We just need to drag these data fields into a table, add a column at the end of the table
and use expression to sum the counts for different OUTCOME. Then we can add a total for the detail row. We have tested this scenario in our local environment. Here are screenshots for your reference:

If you have any question, please feel free to ask.

How can i open a PDF bank statement in numbers so that the rows and columns contain properly aligned data from statement?

how can i open a PDF bank statement in "numbers" so that the rows and columns contain properly aligned data from statement?

Numbers can store pdfs pages or clippings but does not directly open pdf files. To get the bank statement into Numbers as a table I would open the bank statment in Preview (or Skim) or some pdf viewer.
Then hold the option key while selecting a column of data.
Then copy
Then switch to numbers and paste the column into a table
Then repeat for the other columns in the pdf document
It would be easier (in my opinion) to download the QFX or CSV version from your bank

How do I delete multiple rows and columns in an image?

I am looking into how digital SLRs extract video data from a CMOS sensor. To give an example, the GH1 from Panasonic can record video at 1920 x 1080 from a 12 MPixel sensor that, say, is 4000 horizontal x 3000 vertical. How they do that seems to be not in the public domain, but there have been a few guesses (see http://www.dvxuser.com/V6/showthread.php?t=206797 and http://luminous-landscape.com/forum/index.php?showtopic=38713).
One approach would be to simply read every second row of sensor pixels (1500 rows read from the original 3000) and once you have those in memory, delete every second column (2000 columns left). You would end up with a 2000 x 1500 image which could then be resampled to 1920 x 1080.
I'd like to simulate what the camera appears to be doing, by generating a 4000 x 3000 test image and then asking Photoshop CS4 to delete the appropriate rows and columns. It may not necessarily be every second row; the Canon 5DMk11 appears to read every third row, so I may need to delete two out of every three rows.
Can Photoshop do that sort of thing? If so, how?

Thanks for the suggestions. Yes, I did take a detailed look at your images, but they weren't 100% convincing because it wasn't clear just what was happening. And Adobe's explanation, after reading it again, explains nothing at all to someone who doesn't know how Nearest Neighbor works.
But you are correct -- Nearest Neighbor does effectively delete pixels. I proved it with the attached 6 x 6 image of coloured pixels (the tiny midget image right after this full stop -- you'll have to go to maximum zoom in PS to see it).
These are the steps to delete every second row and then every second column.
1. Select Image > Image Size.
2. Set Pixel Dimensions > Height to half the original (in this case set to 3 pixels).
3. Set Resample Image to Nearest Neighbor.
4. Click OK and the image shoould now consist of three vertical white strips and three vertical Green-Red-Blue stripes.
5. Repeat steps 1-4, but this time set Pixel Dimensions > Width to half the original (in this case set to 3 pixels). The image should now consist of three horizontal stripes Green-Red-Blue.
Just to make sure the method worked for every third pixel, I repeated the above steps but with 2 pixels instead of 3 and obtained the correct White-Green, White-Green pattern.
I resampled the Height and Width separately for the test so that I could see what was happening. In a real example, the height and width can be changed at the same time in the one step, achieving the same results as above.
Finally, how to explain how Nearest Neighbor works in the simple cases described above?
Division by 2
In the case of an exact division by two (pixels numbered from top leftmost pixel), only the even numbered rows and columns remain. To put it a different way, every odd numbered row and column are deleted.
Division by 3
Only rows and columns 2, 5, 8, 11... remain.
Division by N
Only rows and columns 2, 2+N, 2+2N, 2+3N... remain.
To put it simply, a resample using Nearest Neighbor (using an exact integer multiple) keeps every Nth row and column, starting from number two. The rest are deleted.

Is it possible to switch the rows and columns?

Is it possible to switch the rows and columns of a table? The reason I ask is that it would be easier for me to input the data with the number at the top of a column and the fields going down. But it would be easier to read the data with the number on the left and the fields going to the right. Is it possible to switch a table in this way?

It sounds to me as though you wish to transpose a table so that the original is changed from rows to columns and from columns to rows, as in the following:
Table 1
 A B C
========
1 o p q
2 r s t
3 u v w
Table 2
 A B C
========
1 o r u
2 p s v
3 q t w
You are right - it would be nice to have a menu item to magically transpose a selected block of cells. But there isn't one. So...
One way to solve this is to use the index() and transpose() functions to accomplish row and column cell transposition. If you are going to use a 1:1 cell correspondence and change the header columns and rows also, you can use this:
 =INDEX(TRANSPOSE(Table # :: <range>),ROW(),COLUMN())
where Table # and <range> is substituted as in the following fashion:
 =INDEX(TRANSPOSE(Table 1 :: $A$1:$C$3),ROW(),COLUMN())
Create a second table. Copy the modified formula above with the appropriate substitutions, select the range you wish to have your transposition inserted into (must match the transposed cell dimensions of the original range), paste the forumula and voila! the cells will be transposed.
Cautions:
o The target table must match the swapped cell length and width dimension. For example, if the original data range is 6 columns wide by 4 rows deep, then the corresponding table or range to hold the transposition must be 4 columns wide by 6 rows deep.
o If your transposed data block is to be offset from the origin of the new table, then you will need to include a subtractive offset into your cell formula, since in the transpose() function the data in the master data range is referenced from its position with the master range, not its cell position in the table. Such an offset is necessary because this example formula uses the target row and column numbers to arrive at indexed positions.
For example, if the new data range is to be offset one column to the right and one row below from the target table's origin then you must subtract (-1) from the cell and from the column references in the formula:
 Example:
 =INDEX(TRANSPOSE(Table 3 :: $B$2:$D$4),ROW()-1,COLUMN()-1)
If someone has a better solution I'd be glad to hear of it.

Keeping row and column headers while scrolling inside a Web Dynpro table

Hi,
I have to display a 2x2 matrix with storage location names on the x-axis (i.e. as Column Headers) and material names on the y-axis (i.e. row headers). The table data represents the quantities of a particular material in a particular storage location.
I am using dynamic UI generation to create this table. It can contain as many as 150 columns and almost as many rows. I dont want a page level scrollbar, and hence, have placed my table inside a scroll container UI element with a fixed height and width.
I need a way to let the users use the scrollbars inside the scroll container, but still let them see the row and column headers. Is there a way that I can do this in Dynpro for Java?
Thanks,
Navneet Nair.

Hi Kenn,
You are probably better off posting this request in this forum User Interface Development in ABAP as you are more likely to get a response.

How can I preserve row and column addresses on multiple cells at once in Numbers?

How can I preserve row and column addresses on multiple cells at once in Numbers 3.2.2? I do a lot of rearranging and sorting and want to reference cells in other sheets. After entering the formulas (example: '=Sheet1::Table 1::H126') I will sort the table and the formulas will not move with the sort. I think I can fix this by going cell by cell checking the 'preserve row' and 'preserve column' boxes when editing the formula. I want to avoid having to go one by one. I know that checking the boxes creates a formula like this: '=Sheet1::Table 1::$H$126' I have also tried entering this manually and filling down but it doesn't include the preservations (the $$) in the autofill. If there is another way to remedy my sorting problem that would also be welcomed!
THANKS!!

The title of the post is this
How can I preserve row and column addresses on multiple cells at once in Numbers?
I restated the Question as follows
Can "Preserve Row" an / or "Preserve Column" be set on multiple cells at the same time.
In both cases it is not asked if multiple cells can be set to....
That is a given.
Step back a second... It is like selecting multiple cells and setting the text color of the currently selected cells to red. This can be done. More than one cell at a time modified because they are currently selected.
Whats is being asked is: if more than one cell is selected at the same time can the settings "Preserve Row" an / or "Preserve Column" be applied. No table I put up will help with that question.
YES or NO
If YES how?

Printing 1 Label in Row and Column Other Than Row 1, Column 1

I want to print 1 label and want to print it on Avery label stock in a row and column other than row 1, column 1. I'm using Avery Labels 8163. I can select the row and column I want to print on in Word but can't figure out how to do it in *Address Book*. Anyone know how to do this?

You can't do that in Addrress Book. But you can use pearLabelizer to do that. Be sure you download and install the appropriate Label Definition file and name it as such so you can select it from the pop-up list in the program's Preferences window.

Referring to Cursor Row and Column in Dynamic SQL

I have a procedure that dynamically reads a schema name and table name from an input table. The code then needs to loop through all rows and columns of each table and output the data. I'm 95% done with what I want to accomplish, but there is one small bug. The line dbms_output.put(*col.column_name* || '',''); ' ||
should refer to something like rec.col.column_name so that it gets the column of the current record. Right now it just displays the column name for each record instead of the actual value. Can anyone help me tweak the code to get the actual value?

Row and Column Template ?

Trying to create this thing but no matter what I do I keep getting this ridiculous error:
Cannot create a linked row and column template based on
the selected rows. The grid needs to have at least one data row that is
not part of a row and column template.
What does this mean?

You can get your requirement done using the Row and Column Template
You can not save a row and column template with all rows in a report. You have to exclude at least one data row, otherwise you
will get the error that you mentioned.
If you want to save all the rows as a template and re-use it in other report, you can insert a data row at the end of all rows and hide that.
Now you can select the complete row set as a template by excluding the extra data row that you will insert & hide.
If you want to link the template in other reports with same row set you must be very careful with the formatting as you need to apply
inherit formatting before saving the template. I suggest to spend some time with the FR online documentation.
