HI can update us two columns at once by the regular update by mentioning two where clauses with respect to columns
The where clause decide which set of lines will be updated.
For example, if the set of rows is not the same for your two columns you must use two sentences--update.
If the rowset is the same for your two columns you can use a single update statement (but then the where clause will be the same).

can perform us two actions with a single button in two clicks, one after the other?
Mr President.
can perform us two actions with a single button in two clicks, one after the other?
I want that when I click on the button Add once it add data to the database and when I click again on this button it clears the form data to the empty fields.
Concerning
Tanvir In the code, it should be easy.
The following code adds that a button called butman with text 'ADD '.
It then registers a listener that will be called if the user clicks the button.
This listener then calls the runAddData method if you clicked butman while it contained the text of "ADD" and it calls the runClearData method otherwise.
That's why he will swap the functionality of the button between ADD and CLEAR on each click.
final Button butman = new Button("ADD");
butman.setOnAction(new EventHandler() {
@Override
public void handle(ActionEvent t) {
if (butman.getText().equals("ADD")) {
butman.setText("CLEAR");
runAddData();
} else {
butman.setText("ADD");
runClearData();
} // END IF-THEN
}});
I hope that's what you wanted.
Further reflection.
You might want to run the ADD and CLEAR methods in their own son so that it can run in the background without slowing down your user interface.
I also reuse rather a single button for several features instead of to apply with hundreds of nodes used only rarely with masses of code to show and hide as needed.

Single line based on two columns and a single column
Dear members,
I have a table that contains duplicate rows, for which a request should be able to extract the unique row in the table. Here the unique is not based on a single column, but it should be in two columns and also check on the uniqueness on a column.
create table addr (varchar2 (10) firstname, lastname varchar2 (10), area varchar2 (3));
insert into values addr ('bob', 'james', 1');
insert into values addr ('bob', 'james', 1');
insert into values addr ('harry', 'bert', ' 1');
insert into values addr ('jimmy', 'bert', ' 1');
insert into values addr ('sam', 'mac', '1');
insert into values addr ('sam', 'Knight', '1');
insert into values addr ('tom', 'sand', '1');
insert into values addr ("cat", "mud", "1");
The query output must contain 3 lines.
Bob - james
Harry - bert or jimmy - bert [or the other of them], but not both
-Mac or sam - Sam Knight [or the other of them], but not both
Tom - sand
Cat - mud
SELECT firstname, lastname as total area WHERE addr = '1' GROUP by firstname, lastname; It takes no duplication of single column...
Any suggestions...

Can we use two columns AS a command
Dear all,
Please suggest
I have two columns of different table and I want to make a general query selection of values in a table based on one exact string of others. Please find the following query:
Select a.col1, b.col2
FROM table1, table2 b
where a.clo3 like b.col4;
Now a.col3 values can be like "asbd %" or "qw %" or "% zx.
where, as in b.col4 it will be asbd or qw or zx.
Please suggest what I would do.
Thanks in advance.
Ankit Rana Hi, stone.
Yes, you can use LIKE this way.
Do not forget that AS is asymmetric:
x LIKE y
is usually not the same as
y LIKE x
because wildcard characters ('%' and '_') have a special meaning in the right operand, which is the expression that comes after LIKE.

So, it seems that you have to reverse the operands of TYPE:
where b.col4 like a.clo3;
By the way, it's a matter of SQL, so a better forum for that would be the [SQL and PL/SQL forum | http://forums.oracle.com/forums/forum.jspa?forumID=75].

Can I merge two Collections into a single?
I have two Collections with similar content... "Oldies" with 138 photos and "Oldies 2" with 93. Maybe I should mention that a few photos in the two Collections.
I want to select and move 'Oldies 2' in 'Oldies' photos by dragging them in the "Oldies".
I then would be left with "Oldies" containing 231pics and "Oldies 2" with it's 93 photos.»
Here's my problem... I would need is more 'Oldies 2' in my Collection can I remove it and he is happy with 150 photos? Or will they removed in 'Oldies' too?
Cliff
If you open 2 Oldies and select all (Ctrl-A or Cmd - A), and then drag these photos in Oldies, you have combined the two collections into a single. Once you are sure that it has been a success, you can remove Oldies 2 without problem.

The combination of two columns in a single
Hi guys,.
Is it possible for a query to combine two columns into one?
For example, lets say I have the following query:
SELECT ID, FIRST_NAME, LAST_NAME
EMPLOYEES
I want the output to have two columns: one that contains the ID and the other containing name followed by a space followed by LAST_NAME. I know how to do this outside the query using coldfusion, but it save me a lot of work if there is some way that the query could do for me. Yes but the operand of concatenation varies somewhat from a database
management system to the other.
In Oracle, it would look this IIRC.
SELECT ID, FIRST_NAME. ' ' || LAST_NAME AS FULL_NAME
EMPLOYEES

Remove the column from the compressed tables
NLSRTL 11.2.0.3.0 Production Oracle Database 11g Enterprise Edition 11.2.0.3.0 64 bit Production PL/SQL 11.2.0.3.0 Production AMT for Linux: 11.2.0.3.0 Production
Hello
I read on how to do to remove a compressed table column - first set unused and then drop unused columns. However, in the example below on the basis of data, I ran it, it does not work. Please, can you tell me WHEN this approach does not work. What is dependent on - settings or something else. Why can't I drop unused columns?
And the example and errors:
create table tcompressed compress in select * from all_users;
> TCOMPRESSED table created.
ALTER table tcompressed add x number;
> table TCOMPRESSED altered.
ALTER table tcompressed drop the x column;
>
Error report:
SQL error: ORA-39726: unsupported operation column add/drag on compressed tables
39726 00000 - "operation column add/drop not supported on compressed tables. ''
* Cause: Not support add/column operation move compressed tables
elapse.
* Action: When adding a column, do not specify a default value.
DELETE column is only supported in a column SET UNUSED
(remove the column metadata).
ALTER table tcompressed unused column of the set x;
> table TCOMPRESSED altered.
ALTER table tcompressed drop unused columns;
>
Error report:
SQL error: ORA-39726: unsupported operation column add/drag on compressed tables
39726 00000 - "operation column add/drop not supported on compressed tables. ''
* Cause: Not support add/column operation move compressed tables
elapse.
* Action: When adding a column, do not specify a default value.
DELETE column is only supported in a column SET UNUSED
(remove the column metadata).
As you can see even after changing the table defining the column as unused X I still can't drop by DROP UNUSED COLUMNS.
Thank you.
If you enable compression for all operations on a table, you can delete the columns in the table. If you enable compression for the only direct-path inserts, you can't remove columns.

So, I have a table:
BLOB_TABLE
Number of BLOB_ID automatically triggered (sequence primary key)
BULLETIN BLOB
BULL_FILE VARCHAR (255)
BULL_MIME VARCHAR (255)
DATE OF BULL_LAST_UPDATE
SUPERFORM BLOB
SUPER_FILE VARCHAR (255)
SUPER_MIME VARCHAR (255)
DATE OF SUPER_LAST_UPDATE
When I try to view a BLOB, it will show only the last BLOB responsible for this record.
Can I store two types of BLOB data in a table? It doesn't seem to matter how I even try to show (even using the 'Download' link attached to traverse file).
Or I have to create two tables and link them together (I'd rather not do that if I have to).
Please notify. Hello
Maybe I just misunderstood your question, but on
Apex. Oracle.com
workspace: put
user: guest

Sorry if this has been asked several times before, I looked but could not find an answer to my specific questions...
Currently, I keep my iPhoto on two different Macs library by periodically copy the package to the main computer entire iPhoto library to an external hard drive, then loading into iPhoto on the second machine.
The problem is that it takes a lot of time and I find myself doing less, which means that I am often without recent photos I want to join the second Mac. Is there a way to copy only the new pictures/videos added since the last copy was made on the hard drive, which I can then add to the library on the second machine without replacing the entire library?
I was wondering if it was possible to use the software of incremental backup to backup on the external drive that I could then use to update the second mac. In this case would be that I have to replace the entire library on the second mac every time, but at least it would be a faster process that also copy entire library since the first mac in the first place.
Or I can just select the most recent photos and videos in iPhoto and batch export via the external hard drive to the second mac? I think I read that this is not copy all information such as good changes? Or am I wrong?
If none of this is possible in the way that I'm demanding, could someone suggest an alternative photo storage software for Mac that I can have more control on?
Yes, you can use an incremental backup or clone (like Carbon Copy clone or SuperDuper) program for updating the second library - this will not libraries merge in order to not do that is you make changes to the second library on this machine - it only makes library 2 exactly as 1 library each time that you run

How to upgrade all the updates of Windows XP from a single package?
Original title: Windows XP updates
Is there an SP4 or a package that contains all of the updates of Windows XP after SP3 is released? It would be extremely useful to update all of the XP machines that do not have access to the internet.
There will be a version called SP4 update by private parties. This update has been treated since September of 2012. Currently, they are still working on it. You can access this information to
http://www.RyanVM.NET/forum/viewforum.php?f=5&SID=3058537efee42c994a4945a016f82cc3
Hope this helps, they recommend you to read the info from the beginning. With files and information, you can create an ISO file that can be used to create a version of XP from microsoft that you can use in the future. I do not recommend to use a good firewall and antivirus program to protect your system like back up your system regularly.
Personally, I'm going to build me a new computer.
