Selecting a one pixel high row of a table

I have created a table about 18 rows high and have one row 1 pixel high. It is colored black to separate sections.
I am unable to select it to erase it. I have zoomed in, also tried the table palette.
Any ideas?

Wich function (class) could I use to create one pixel high object (frame)?

Hi guys, I need a pointer on a certatin line on the graphic screen. And I want it to be written in Java. I know how to make it to be "always on top" now, but AFAIK every applet or application is to be shown in a bordered window saying it is a Java object for security reasons. As I want it to be one pixel high, I apparently need to get rid of the frame border. Supposedly I have to switch off the security, but it's OK for me.
Wich function (class) do I use to create one pixel high object?
And one more thing. How do I generally show a graphic object of nonrectangular shape out of the bordered frame? Is there a way to do it without creating an transparent rectangular window/frame?

I didn't quite know what you mean, but how's this?
public class MySinglePixelWindow extends JWindow {
   public MySinglePixelWindow() {
      super();
      setSize(1,1);
      setLocation(0,0);
   public void paint(Graphics g) {
      super.paint(g);
      g.fillRect(0,0,1,1);
}Transparent Window:
public class MyTransparentWindow extends JWindow {
   java.awt.Robot robot;
   BufferedImage screen;
   public MyTransparentWindow() {
      super();
      try {
         robot = new Robot();
      } catch(Exception e) {}
   public void show() {
      image = robot.createScreenCapture(getBounds());
      super.show();
   public void paint(Graphics g) {
      super.paint(g);
      Graphics2D g2 = (Graphics2D)g;
      g.setComposite(AlphaComposite.newInstance(AlphaComposite.SRC_OVER,0.8));
      g.drawImage(image,0,0,this);
}Puh!
You can't move this window though...

Select and highlight a default row in a table

Hi everybody.
When using a table in WD, the first line is selected and highlighted by default.
I'd like to reproduce the same behaviour but this time, the selected and highlighted row shouldn't be the first row but any other one that has to be defined previously.
How could I do that??
Thanks for any suggestions you may have.
Regards,
C.

For example I have a node SFLIGHT which am using to display data in tabular format on my layout. I have attached a supply function POPULATE_DATA to my context node SFLIGHT to fetch & populate the node.
METHOD populate_data .
DATA: lt_sflight TYPE wd_this->elements_sflight.
SELECT carrid
         connid
         fldate
         price FROM sflight INTO TABLE lt_sflight.
node->bind_table( new_items = lt_sflight ).
ENDMETHOD.
And within my WDDOINIT method am programmatically setting the LeadSelection to the 3rd row as how shown below:
METHOD wddoinit .
DATA: wd_node TYPE REF TO if_wd_context_node.
wd_node = wd_context->get_child_node( name = 'SFLIGHT' ).
wd_node->set_lead_selection_index( '3' ).
ENDMETHOD.

One pixel around borderless image in table

Hey,
I have an image in a table. I set the background color of the
table to a greyish blue, because the table is taller than the image
and i want there to be color below the image in the table. BUT ONLY
in the table. The width of the table is the same as the image. For
some reason, there is one pixel of the background color of the
table around the jpg, and I cant get it to go away. I tried
cellpadding="0", but that didn't do anything. I also tried negative
numbers, but taht didnt do anything either. Am I SOL or can I put
this image in the table without having the background exceed the
image?
Simple:
<table width="600" border="0" align="center">
<tr>
<td width="216"
background="../../Images/tablebgcolor.jpg"><img
src="../../Images/Old Main.jpg" alt="" width="216"
height="332"/>
</td>
<td width="374"> </td>
</tr>
</table>
Note that I used the image of the background color instead of
setting the background color itself. In either case it's the same,
and I can't get a different result. Thanks for the help,
--G

What happens if you remove the tag around the
image?
 tags have a default padding, so unless you zero
that out or move the
image of of the you'll get some spacing around it.

Howto create 'select statement' that returns first row? (simple table)

quick question that drives me crazy:
Say I have the following table:
ID....car_model....point_A....total
1........333.............NY..........54
2........333.............NJ..........42
3........333.............NH...........63
4........555.............NJ...........34
5........555.............PA...........55
I would like to create a select statement that return car_model which the starting point is NJ - in this example it's only 555.
thanks for any tips

fair enough.
the problem is this: given the table below, I need to create a report that reflects car rentals from specific location. you can rent a car from different locations; a car has a starting point (like a flight itinerary) so consider this:
Mark rent a car with the following itinerary:
NY--> NJ
NJ--> PA
PA-->FL
FL-->LA
the end user would like to see all car that were rented between X and Y and start point was NJ, so in the example above, the starting point is NY so it doesn't match the end users' criteria.
The table is organized in the following manner: ID....car_model....point_A....total
* I don't know whey the someone choose point_A as a column description as it just suppose to be 'location'
so, back to my first example:
ID....car_model....point_A....total
1........333.............NY..........54
2........333.............NJ..........42
3........333.............NH...........63
4........555.............NJ...........34
5........555.............PA...........55
if I do this:
Select car_model from myTable where point_A='NJ'
the return result will be 333 and 555 but that is in correct because 333 starting point is NY.
I hope I provided enough information, thanks

How do I select the end of a row or column in Numbers?

I am trying to select to the end of a column in Numbers. In Excel, I simply hold down the shift+command+arrow keys and I can select the entire row or column int he arrow direction. How do I do this in Numbers?

Here two other scripts :
Select-to-top and select-to-left.
Both of them take care of possible headers.
--{code}
--[SCRIPT select-to-top]
Enregistrer le script en tant que Script : select-to-top.scpt
déplacer le fichier ainsi créé dans le dossier
<VolumeDeDémarrage>:Utilisateurs:<votreCompte>:Bibliothèque:Scripts:Applications :Numbers:
Il vous faudra peut-être créer le dossier Numbers et peut-être même le dossier Applications.
Sélectionner une ou plusieurs cellules d'une ligne dans une table de Numbers
Aller au menu Scripts , choisir Numbers puis choisir “select-to-top”
Il étendra la sélection jusqu'à la première ligne standard de la colonne (ne sélectionne pas les rangs d’en tête).
Bien entendu, ce script sera plus intéressant si vous le dotez d'un raccourci clavier à l’aide, par exemple, de FastScripts.

Select one or several cells in a row of a Numbers table.
Go to the Scripts Menu, choose Numbers, then choose “select-to-top”
It will expand the selection to the first standard row of the table (minus header rows).
Of course, it would be more useful if you attach a shortcut thanks to a tool like FastScripts.

Last Inserted Row in a Table

Hi,
I want to select only the last inserted row in a table. Can anybody help me how can i get it.
Eg
select * from emp;
empno ename sal
12 abc 100
13 xyz 200
Now i have inserted a row as
Insert into emp values (14,'Rohit',500);
So i only want to select the last inserted row i.e.. empno 14 (in this case).
Thanks
Bye
Rohit Taneja

Thanks to all for replying.
But the result is not which i desire.
I have deleted the existing row in the same table as
SQL> Delete from emp where empno = 13;
1 row deleted.
Then i inserted a new row as
SQL> insert into emp values(10,'SRI',200);
1 row created.
Then i committed the work
SQL> commit;
Commit complete.
But still am getting the last row as
SQL> select * from emp
where rowid=(select max(rowid)
from emp);
EMPNO ENAME SAL
14 ROHIT 500
as the solution.
But here i am supposed to get the row with empno 10.
I have tried both the queries and still geting the same result.
Please look aat it again,
Thanks in advance

Selecting only one row at a time

Hi experts,
i have following doubt regarding selecting rows from a db:
Is there any way of selecting only one row AT A TIME from a dabase just to collect the data in rows instead of in a unique document containing all the rows?
I would like you to ellaborate on this as i need to send only one row to the IE, and then other row, and so on... without throwing any error!
I have seen that there are SELECT SINGLE and SELECT UP TO 1 ROW, but these two methods are only useful when retrieving only one row, and that does not match my requirements. I need to process all the rows but one by one..
I know that we can use the receiver jdbc adapter as if it was a sender by means of its specific datatype, but how to do it row by row??
Hope i had explained well..
Thanks in advance and best regards,
David

Hi kiran,
Yes, my table has 5 not null fields but i am selecting and updating fixes values so i think that I will definetely go for the next solution:
SELECT * FROM t1 WHERE status='0' and ROWNUM<2;
UPDATE t1 SET status='1' WHERE status='0' and ROWNUM<2;
My only concern is if the update will take the same row that the select.... BTW, I think it will
..What do you guys think?
I ve been trying to operate with your proposed queries but i received some errors. Your queries are very interesting but i think that with the above ones i meet my requirements as the status field will be 0 for not processed rows and 1 for precessed ones (and the update will look for the row that meets the same 'where' clause than the select, and then, and only then, it will set status='1').
The only thing i have to care about is what i questioned before.
Thanks a lot and best regards,
David

How to select one row in a table with radio button

Hi all.
I have a VO where there is an attribute (isDefault [String]) that identifies the default record in the view. The possible values are 'Y' for yes and 'N' for no. Obviously only one record can have the 'Y' value.
In my page I have created an ADF Table (with the usual data control drag & drop). I would to transform the default inputText of "isDefault" field with a selectOneRadio component in order to permit the user to select (and save contextually in the DB) the default row of this table.
Can you explain me how? I'm using JDeveloper 11.1.1.4.
Thanks in advance.

Cvele,
thanks for your responses. Yes, it's easier to use af:selectBooleanCheckbox but I need that the selection is mutually exclusive (only one row can be selected). >If this is possible also with the boolean checkbox please tell me how.- Let's try with CheckBox :
1. At the ViewObjectImpl level (for example, YourViewObjectImpl), add the following code:
private oracle.jbo.Key currSelectedRowKey = null;
public void doRowSelection(Key newKey) {
      // de-select old one
      if (currSelectedRowKey != null) {
          Row[] rows = findByKey(currSelectedRowKey, 1);
          if (rows != null && rows.length > 0)
               rows[0].setStatusAsBoolean(Boolean.FALSE); // cast to the appropriate row Impl class if need !
     // remember a new selected row key:
    currSelectedRowKey = newKey;
}In the ViewRowImpl, in the transient attr settter, do as follows:
public void setStatusAsBoolean(Boolean value) {
     setStatus(value.booleanValue() ? ONE : ZERO);
     if (value.booleanValue()) {
         YourViewObjectImpl vo = (YourViewObjectImpl)getViewObject();
         vo.doRowSelection(getKey());
   }   P.S. The above was not tested at all, but should give you an idea

ALV to select more than one column by row using set_table_for_first_display

Hello everyone,
I am developing an application (ALV OO) to select more than 1 column by row ( one ). This is an a holiday application so the idea is:
-One column will be the day, and the row will be the user.
So I am trying to select more than one day by user (that would be the row).
I am using the method set_table_for_first_display but when it shows the alv, doesn't let me to select more than one column with a click of the mouse.
Does anybody know if I can do this (select more than one column, by row) in somehow?
Please let me know if you need more clarification about this.
Thanks in advance

Hi Diego,
it's all in the documentation.
set different selection modes through the value of the field u201CSEL_MODEu201D in the layout structure.
SPACE
same as 'B'
see 'B'
Default setting
'A'
Column and row selection
Multiple columns
Multiple rows
The user selects the rows through pushbuttons at the left border of the grid control.
'B'
Simple selection, list box
Multiple columns
Multiple rows
'C'
Multiple selection, list box
Multiple columns
Multiple rows
'D'
Cell selection
Multiple columns
Multiple rows
Any cells
The user selects the rows through pushbuttons at the left border of the grid control
Beyond setting this option, you can set u201CNO_ROWMARKu201D option to hide the mark column which is normally visible when the selection mode allows multiple row selection.
One point to notice here is that if you set your ALV Grid as to be editable, it may override your selection mode regardless of your layout settings.

The DataDirect-ODBC-driver is not possible, because we like to use the free MySQL-database an DataDirect only support the enterprise edition.
I also have tried to limit the HS_OPEN_CURSORS or dont limit the HS_FDS_FETCH_ROWS, but there is no difference in the result. I always get only one row.

Bianca,
If you log directly into MySQL and issue the same query (select "subject" from "main_pages";) what data is returned?
I looks to me that you count is the number of rows in the entire table "main_pages"
while you select is for the data in the "subject" column only.
This seems to indicate that you have just one row in that subject column.

WHAATT?
What do you mean by "just one row in that subject column"?
That makes no sense at all. A row is a row. A column is a part of a row. All rows have all columns, though not all columns of all rows will necessarily have an assigned value. Lacking a WHERE clause to filter rows, any SELECT should return all rows.

Select Single * and Select upto one row

Hi all,
Can anybody tell me what is difference between Select single * and select upto one row?
And which one is better?
Thanks in advance.......

According to SAP Performance course the SELECT UP TO 1 ROWS is faster than SELECT SINGLE because you are not using all the primary key fields.
select single is a construct designed to read database records with primary key. In the absence of the primary key, it might end up doing a sequential search, whereas the select up to 1 rows may assume that there is no primary key supplied and will try to find most suitable index.
The best way to find out is through sql trace or runtime analysis.
Use "select up to 1 rows" only if you are sure that all the records returned will have the same value for the field(s) you are interested in. If not, you will be reading only the first record which matches the criteria, but may be the second or the third record has the value you are looking for.
The System test result showed that the variant Single * takes less time than Up to 1 rows as there is an additional level for COUNT STOP KEY for SELECT ENDSELECT UP TO 1 ROWS.
The 'SELECT SINGLE' statement selects the first row in the database that it finds that fulfils the 'WHERE' clause If this results in multiple records then only the first one will be returned and therefore may not be unique.
Mainly: to read data from
The 'SELECT .... UP TO 1 ROWS' statement is subtly different. The database selects all of the relevant records that are defined by the WHERE clause, applies any aggregate, ordering or grouping functions to them and then returns the first record of the result set.
Mainly: to check if entries exist.
Select Single is the best one compared to UPto one rows.
Select Single will get the first record from the table which satisfies the given condition.So it will interact once with the database.
UTO 1 rows will get the list of the records for the given match and iwll show the first record from the list.So it will take time to get the record.
SELECT SINGLE VBELN from VBAK
where MATNR = '1M20'.
---Thjis will get the first matched record and will display the record
SELECT VBELN from VBAK
where MATNR = '1M20' upto 1 rows.
---Thjis will get the list of matched records and will display the first record
The Major difference between Select Single and Select UPTO 1 rows is The Usage Of Buffer for each.
Select Single will search for all the satisfied data and bring all that data into Buffer and later it will give to that data to the program.
Select UPTO 1 Rows will end the search after getting the 1st satisfied record and gives that record to the program.
Thus Select Single will take much processing time when compare with Select UPTO 1 rows.

Fetching more than one row from a table after selecting one value from the dropdown

Hi Experts,
How can we fetch more than one row from a table after selecting one value from the dropdown.
The scenario is that I have some entries in the dropdown like below
A B C
11256 VID 911256
11256 VID 811256
11256 SONY 11256
The 'B' values are there in the dropdown. I have removed the duplicate entries from the dropdown so now the dropdownlist has only two values.for eg- 'VID' and'SONY'. So now, after selecting 'VID' from the dropdown I should get all the 'C' values. After this the "C' values are to be passed to other methods to fetch some data from other tables.
Request your help on this.
Thanks,
Preeetam Narkhede.

Hi Preetam!
I hope I understand your request proberly, since this is more about Java and less about WebDynpro, but if I'm wrong, just follow up on this.
Supposed you have some collection of your original table data stored in variable "origin". Populate a Hashtable using the values from column "B" (let's assume it's Strings) as keys and an ArrayList of whatever "C" is (let's assume String instances, too) as value (there's a lot of ways to iterate over whatever your datasource is, and since we do not know what your datasource is, maybe you'll have to follow another approach to get b and c vaues,but the principle should remain the same):
// Declare a private variable for your Data at the appropriate place in your code
private Hashtable temp = new Hashtable<String, ArrayList<String>>();
// Then, in the method you use to retrieve backend data and populate the dropdown,
// populate the Hashtable, too
Iterator<TableData> a = origin.iterator();
while (a.hasNext()) {
 TableData current = a.next();
 String b = current.getB();
 String c = current.getC();
 ArrayList<String> values = this.temp.get(b);
 if (values == null) {
 values = new ArrayList<String>();
 values.add(c);
 this.temp.put(b, values);
So after this, you'll have a Hashtable with the B values als keys and collections of C values of this particular B as value:
VID --> (911256, 811256)
SONY --> (11256)
Use
temp.keySet()
to populate your dropdown.
After the user selects an entry from the dropdown (let's say stored in variable selectedB), you will be able to retrieve the collection of c's from your Hashtable
// In the metod you handle the selection event with, get the c value collection
//and use it to select from your other table
ArrayList<String> selectedCs = this.temp.get(selectedB);
// now iterate over the selectedCs items and use each of these
//to continue retrieving whatever data you need...
for (String oneC : selectedCs) {
 // Select Data from backend using oneC in the where-Clause or whatever...
Hope that helps

Diffrence b/w select single & select upto one row

hi
wat is the diffrence b/w select single & select upto one row?
deepak

Hi,
Select single has to be used with a where condition that has all the key fields:
It will always return a unique record(If a match is found).
Select upto 1 rows would get your the first record if multiple matches are found.
and select up to has to be end with endselect statements.
According to SAP Performance course the SELECT UP TO 1 ROWS is faster than SELECT SINGLE because you are not using all the primary key fields.
select single is a construct designed to read database records with primary key. In the absence of the primary key, it might end up doing a sequential search, whereas the select up to 1 rows may assume that there is no primary key supplied and will try to find most suitable index.
The best way to find out is through sql trace or runtime analysis.
Use "select up to 1 rows" only if you are sure that all the records returned will have the same value for the field(s) you are interested in. If not, you will be reading only the first record which matches the criteria, but may be the second or the third record has the value you are looking for.
The System test result showed that the variant Single * takes less time than Up to 1 rows as there is an additional level for COUNT STOP KEY for SELECT ENDSELECT UP TO 1 ROWS.
The 'SELECT SINGLE' statement selects the first row in the database that it finds that fulfils the 'WHERE' clause If this results in multiple records then only the first one will be returned and therefore may not be unique.
Mainly: to read data from
The 'SELECT .... UP TO 1 ROWS' statement is subtly different. The database selects all of the relevant records that are defined by the WHERE clause, applies any aggregate, ordering or grouping functions to them and then returns the first record of the result set.
Mainly: to check if entries exist.
When you say SELECT SINGLE, it means that you are expecting only one row to be present in the database for the condition you're going to specify in the WHERE clause. so that means, you will have to specify the primary key in your WHERE clause. Otherwise you get a warning.
SELECT UP TO 1 ROWS is used in cases where you just want to make sure that there is at least one entry in the database table which satisfies your WHERE clause. Generally, it is meant to be used for existence-check.
You may not want to really use the values returned by the SELECT statement in this case (thought this may not necessarily be so).And in each case the database optimizer may choose a different strategy to retrieve the data.
Knowing when to use SELECT SINGLE or SELECT ... UP TO 1 ROWS
A lot of people use the SELECT SINGLE statement to check for the existence of a value in a database. Other people prefer to use the 'UP TO 1 ROWS' variant of the SELECT statement.
So what's the difference between using 'SELECT SINGLE' statement as against a 'SELECT .... UP TO 1 ROWS' statement ?
If you're considering the statements
SELECT SINGLE field INTO w_field FROM table.
and
SELECT field INTO w_field FROM table UP TO 1 ROWS. ENDSELECT.
then looking at the result, not much apart from the extra ENDSELECT statement. Look at the run time and memory usage and they may be worlds apart.
Why is this ?? The answer is simple.
The 'SELECT SINGLE' statement selects the first row in the database that it finds that fulfils the 'WHERE' clause If this results in multiple records then only the first one will be returned and therefore may not be unique.
The 'SELECT .... UP TO 1 ROWS' statement is subtly different. The database selects all of the relevant records that are defined by the WHERE clause, applies any aggregate, ordering or grouping functions to them and then returns the first record of the result set.
