Sorting rows by choosen column.

What kind of Array(Map, or any other data structure) should I use, if i want sort all rows by values in j-th column.
Suppose i need to store data like this:
Name | Surname | Telephone
---------| ---------------|--------------
Dawid| Olaf | 3422353
Jack | Ugly | 7872347
Mike | Opis | 38483848
And now i want sort all rows by Surname.
Is there any covenient data structure to make such things ?

Why you asking for ?
I'm simply not familiarize with data structures in java and i thought that there is data structure in java like array, with possibility of sorting rows by choosen column.
I think the only way to do that is use sortAllRowsBy(DefaultTableModel model, int colIndex, boolean ascending).

Sort Rows by Color?

I have color coded some of the rows for a project I'm working on and would love to sort all the 'colored' rows together. Is there a way to sort by the color that I've chosen to fill each row with?
When I had only two colors I was using a workaround. I added a check-box column and had one color = a check mark. That allowed me to sort the checkbox column. Now I have four colors and this doesn't work any more.
Any ideas?

Quick & dirty solution:
Add a column with the header marked 'color'
Then use numeric or text entries: Red, Blue, Green, Black, 1, 2, 3, 4 ... a, b, c, d, or whatever for your color codes in that column.
Then sort by the 'color' column.
Now mark the 'color' column as hidden.

Sort rows by fill color?

Is it possible in Numbers to sort rows based on the row fill color? There are only 2 colors the rows have as background (fill), and it would save time to sort based on the highlighted row. Any ideas?
Thank you-

I agree with jerrold.
I will certainly not ask Apple for such a feature.
Here is a script which may give you an efficient response.
property columnOffset : 2
tell application "Numbers"
activate
set {rName, tName, sName, dName} to my getSelection()
if (character 2 of rName) as text > "9" then
set columnLetter to text 1 thru 2 of rName
else
set columnLetter to character 1 of rName
end if
set twoNames to my decoupe(rName, ":")
set {colNum1, rowNum1} to my decipher(item 1 of twoNames)
set columnToSort to colNum1 + columnOffset
tell document dName to tell sheet sName to tell table tName
set myColor to background color of (get properties of range rName)
set nbRows to count rows
repeat with r from 1 to 14 --nbRows
set val to background color of (get properties of range (columnLetter & r & ":" & columnLetter & r))
set val to (val is myColor)
set value of cell r of column columnToSort to val
end repeat
end tell
end tell
--=====
on getSelection()
local mySelectedRanges, sheetRanges, thisRange, _, myRange, myTable, mySheet, myDoc, mySelection
tell application "Numbers"
activate
tell document 1
set mySelectedRanges to selection range of every table of every sheet
repeat with sheetRanges in mySelectedRanges
repeat with thisRange in sheetRanges
if contents of thisRange is not missing value then
try
--return thisRange --poorly formed result
thisRange as text
on error errMsg number errNum
set {_, myRange, _, myTable, _, mySheet, _, myDoc} to my decoupe(errMsg, quote)
--set mySelection to (a reference to (range rn of table tn of sheet sn))
return {myRange, myTable, mySheet, myDoc}
end try
end if -- contents…
end repeat -- thisRange
end repeat -- sheetRanges
end tell -- document 1
end tell -- application
return {missing value, missing value, missing value, missing value}
end getSelection
--=====
on decipher(n)
local letters, colNum, rowNum
set letters to "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
if (character 2 of n) as text > "9" then
set colNum to (offset of (character 1 of n) in letters) * 64 + (offset of (character 2 of n) in letters)
set rowNum to (text 3 thru -1 of n) as integer
else
set colNum to offset of (character 1 of n) in letters
set rowNum to (text 2 thru -1 of n) as integer
end if
return {colNum, rowNum}
end decipher
--=====
on decoupe(t, d)
local l
set AppleScript's text item delimiters to d
set l to text items of t
set AppleScript's text item delimiters to ""
return l
end decoupe
--=====
Select a cell with the color to use in the sort.
Run the script.
It will fill the column whose offset from the selected one is defined by the property 'columnOffset'
If the background of the cell in the source column is the searched one the value will be 1
if the background is not this one, the value will be 0.
So it will be easy to use a condition.

MS Query...cannot write sorted rows error

I have an MS Query report crated and it was working well until i tried to remove a Criteria Filter within the query. I get an error "Cannot Write Sorted Row". If I acknowledge the error, the change to the criteria is not saved and it reverts to
the original setting. I had several columns sorted, of which i deleted the SQL code for sort thinking that may help. I also tried to delete the Criteria Filter via the wizard and directly in SQL but that did not help.
Any suggestions of what may be the issue?

This is a Power Query forum and so it's unlikely you'll find MS Query experts here. That being said, did you try using Power Query for your scenario?

How to transpose rows into multiple columns using pivot table

I have 1 row containing 12 columns with value "JAN", "FEB", "MAR", "J-1","F-1","M-1","J-2","F-2","M-2","J-3","F-3","M-3"
I want to display as
JAN J-1 F-1 M-1
FEB J-2 F-2 M-2
MAR J-3 F-3 M-3
How do I achieve the above?

Today you have only 3 months JAN, FEB, MAR. Is it always the same number of columns. What if there are more months added to this row?
Is your data really coming from relational source or some sort of text file?
There is a better way to do this in narrative view using HTML if your requirement is just to show them in multiple rows and do some calculations.
Go to Narrative View;
In prefix, use <html> <table>
In 'Narrative' text box add something like this
<tr> <td> @1 </td> <td> @4 </td> <td> @7 </td> </tr>
<tr> <td> @2 </td> <td> @5 </td> <td> @8 </td> </tr>
<tr> <td> @3 </td> <td> @6 </td> <td> @9 </td> </tr>
In Suffix, use </table> </html>
You can also add simple calculations like sum etc at the very bottom of these rows as grand totals.

Sort rows in JTable except the last row

Hi All,
I have a JTable, which contains columns with numbers. The last row contains column sums.
I want to be able to sort rows, but the last row with sums must remain motionless.
Does anyone know the solution of this problem?
Thanks in advance.

These two posts are my example. It works pretty good but there is one significant niggle - when moving a column the 'total' table does not move smoothly but it does move. I look forward to 'camickr' reducing this to about 1 line.

Changed the layout of the inner panel so that the secondary table is now in the CENTER. This stops the secondary table becoming detached from the primary when one expands the frame beyond the prefferred size.

Converting each row in a column to an XML

Hi everyone,
Using Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit
I have a table where there is a comments column which is VARCHAR2. That column contains string data in the form of XML tags.
Like for eg. *<tag_name attr_name="10"/>* (sorry cant provide the exact values as I'm not allowed to)
There are many such rows. Now I want to use these strings and operate on them as XML like using XPath to find certain attributes etc.
I tried using the extract function and to use it i need a XMLType object. So I tried to create one using the XMLType() constructor.
But it gives me the error ORA-19032: Expected XML tag , got no content
When I looked it up on the net, I found that this error number doesn't correspond to the error message that I'm getting. The error msg found on the internet was Expected XML tag string got string
I used this query
SELECT XMLType (<column>) FROM <table>;But when I modified it (based on someone's hunch) to
SELECT XMLType (<column>)
FROM <table>
WHERE ROWNUM <= 1;The query worked fine. Like it can take only one row.
I also tried like this
SELECT XMLType ('<tag_name attr_name="10"/>')
FROM DUAL;This too worked fine.
So finally this has left me completely confused. Is there a way to convert every row in a column to an XMLType object so that I can use the extract function to gather information about it.
For the time being I have used REGEXes to write the code. But having the flexibility of xml would be better.
Any help would be appreciated.
Regards,
Arijit

Arijit,
The error message is correct. What you found is merely the generic message with string placeholders.
The error message is also pretty self-explanatory : you can't pass an empty string (NULL) to the XMLType constructor.
SQL> select xmltype('') from dual;
ERROR:
ORA-19032: Expected XML tag , got no content
ORA-06512: at "SYS.XMLTYPE", line 310
ORA-06512: at line 1
no rows selectedYou have to either add a WHERE clause to filter out NULL columns, or use a CASE statement to only convert strings that aren't empty :
SELECT XMLType (<column>)
FROM <table>
WHERE <column> IS NOT NULL ;
SELECT CASE WHEN <column> IS NOT NULL THEN XMLType (<column>) END
FROM ...And do not use EXTRACT if you want to access scalar values, use EXTRACTVALUE instead :
SQL> select extractvalue(xmltype('<tag_name attr_name="10"/>'), '/tag_name/@attr_name') from dual;
EXTRACTVALUE(XMLTYPE('<TAG_NAMEATTR_NAME="10"/>'),'/TAG_NAME/@ATTR_NAME')

On ALV report in1 column I want to put Icon on every row of that column.

On ALV report there is 1 column I want to put Icon on every row of that column.That ALV program uses object oriented concept all class and methods.
I want to use that icon on that row. That icon name is ICON_OKAY
In my program when I assign values to internal table at that time I am assigning that ICON_OKAY value to that row as follow.
Itab-
Itab-icon = ICON_OKAY.
Append itab.

please follow below procedure to display icon in ALV
1) In corresponding fieldcatelog entry do
fieldcatalog-icon = 'X'
2) While filling the internal table fill the corresponding key value of icon , for example ICON_OKAY value is '@0V@' so statement would be
Itab-icon = '@0V@'
to get list of corresponding key for icon open include <ICON> in se38

Different number of rows for different columns in JTable

hi
I need to create a JTable with different number of rows for different columns...
Also the rowheight should be different in each column...
say there is a JTable with 2 columns... Col1 having 5 rows and column 2 having 2 rows...
The rowHeight in Col2 should be an integer multiple of Rowheight in Col1
how do I do this ??
can anybody send me some sample code ?????
thanx in advance

How about nesting JTables with 1 row and many columns in a JTable with 1 column and many rows.
Or you could leave the extra columns null/blank.
You could use a GridBagLayout and put a panel in each group of cells and not use JTable at all.
It would help if you were more specific about how you wanted it to appear and behave.

You will need to create a custom renderer to display both an image and text. Renderers are assigned to a column. If you require different renderers for a given row in a column then you will need to override the getCellRenderer(...) method to return a renderer for the specific row.

How to get difference between two rows for a column field?

hi, all,
Could anyone show me what query statement is to get the difference betweem two rows for two column fields?
The tables and its records are like this:
id,      begin,      end
p1         21          30
p2          45          60
p3          120          150
I would like to have the query result like this
id,    diff
p1     15    --- which is 45 minus 30
p2     60    --- which is 120 minus 60
and so on...
thank you in advance.

You can use the LAG function to access values from previous rows:
with q as (select 'p1' id, 21 v_start, 30 v_end from dual
union all
select 'p2', 45, 60 from dual
union all
select 'p3', 120, 150 from dual)
select id, v_start, v_end, v_start - lag (v_end, 1, 0)
over (order by id) v_diff from q
ID,V_START,V_END,V_DIFF
p1,21,30,21
p2,45,60,15
p3,120,150,60
