Help with SELECT command

I have 2 tables (Table1 and Table2) , I want to select all the rows form Table1 and show in an extra column what rows does exist or not in Table2.
Something like that:
Column1, Column2, ExistInTable2
a a YES
b b YES
c c NO
d d YES
e e NO
How do i do that SQL statement?
SELECT column1, column2, ¿xxxxx? FROM Table1?
Thanks

I think you want the second option:
SQL> SELECT d.*,DECODE(e.deptno,NULL,'NO','YES')
2    FROM dept       d
3        ,emp        e
4   WHERE d.deptno   = e.deptno(+)

Help with SELECT - selecting range of numbers

Hi,
I need a help with SELECT statement. I want to select Dates starting from today and ending 30 days back. So the result would be like:
TRUNC(SYSDATE)
TRUNC(SYSDATE) - 1
TRUNC(SYSDATE) - 2
TRUNC(SYSDATE) - 3
TRUNC(SYSDATE) - 30I was thinking to simply select truncated SYSDATE in first column, and in second column numbers 0, 1, 2, ... 30. Then I would simply do a difference first column - second column. But how to select such sequence of numbers? I don't want to select each number (date) in separate select statement and then unioning them.
Does anybody have an idea?
Thanks for help, Dan

Help with selecting chuncks of data from a table

Hi all,
I need help with a query that should do the following.
I have a table with vessel messages, and I need to get the last "NumMsgs" messages from a group of vessels.
The problem I have is that if I order the table by Vessel_ID, MessageDate DESC, I can´t do ROWNUM < NumMsgs (<-- Then number of messages to be shown is a user parameter)
I know it should be something like:
select * from (
select *
from Messages m
where TRIM(m.V_ID) = '11597' /* I was trying for a single vessel atm */
order by m.V_ID, m.MESSAGEDATE desc
where rownum < :NumMsgs
Any ideas?
Thanks in advance !

Hi,
What about :
select *
from (
select m.*, row_number() (order by m.V_ID, m.MESSAGEDATE desc) rn
from Messages m
where TRIM(m.V_ID) = '11597' /* I was trying for a single vessel atm */
where rn < :NumMsgsAnyway, I don't very well understand your problem, your query work fine, see for example :
SQL> ed
Wrote file afiedt.buf

Help with a Command script

Hello,
Awhile back someone wrote the following script for me. The
idea was to make a comman that would allow me to reduce an image
down to 400 pixel width without loss of scale. I want to have a
similiar command that will reduce a large image down to 400 pilel
height without loss of scale. I fiddled with the command for width
but can't get it to work for height. Can I get some help rewriting
the following command to work for 400 pixel height? Thanks.
// User Variables
var width = 400;
// Command
var dom = fw.getDocumentDOM();
var scale = width/dom.width;
var height = dom.height * scale;
dom.setDocumentImageSize({left:dom.left, top:dom.top,
right:dom.left+width, bottom:dom.top+height},
{pixelsPerUnit:dom.resolution, units:dom.resolutionUnits});

> I did try it that way. But I could not get it to work.
The word "scale" is critical, but I switching did not help.
Just switch the variables word for word. Height for width and
width for
height.
// User Variables
var width = 400;
// Command
var dom = fw.getDocumentDOM();
var scale = width/dom.width;
var height = dom.height * scale;
dom.setDocumentImageSize({left:dom.left, top:dom.top,
right:dom.left+width,
bottom:dom.top+height}, {pixelsPerUnit:dom.resolution,
units:dom.resolutionUnits});
// User Variables
var height = 400;
// Command
var dom = fw.getDocumentDOM();
var scale = height/dom.height;
var width = dom.width * scale;
dom.setDocumentImageSize({left:dom.left, top:dom.top,
right:dom.left+width,
bottom:dom.top+height}, {pixelsPerUnit:dom.resolution,
units:dom.resolutionUnits});
Once you see this script, it's not hard to see what it is
doing.
This is the Fireworks generated script scaling just the
height of an
image to 400 px from 640x480 px.
fw.getDocumentDOM()
.scaleSelection(0.83281248807907104, 0.83333333333333337,
"autoTrimImages transformAttributes");
This works on all 640x480 images. Throw in a 700x480 and it
won't.
I'm assuming, very few people in here (myself included),
would be able
to transform this into something that would account for
varying widths
as senocular did.

Help with Expect command to change config on hundreds of ASA's.

Hi All,
I'm looking for some help with the Expect command to automate some tasks, I'm certainly no programmer but I am struggling, here is an example of my script.
#!/usr/bin/expect -f
# This simple Expect script will add a new Syslog destination in
# Cisco switches (IOS based)
# We assume here that all switches uses the same credentials
# for the administrative tasks
# Define variables
set password "site1"
set enablepassword "site1"
# Define all the switches to be reconfigured (separated by spaces)
set switches "site1 site2 site3"
# Main loop
foreach switch $switches {
        puts "Processing switch: $switch";
        # Open the telnet session:
        spawn telnet $switch
        # Perform authentication
        expect "Password:"
        send "$password\r"
        expect ">"
        # Switch to enable mode
        send "en\r"
        expect "Password:"
        send "$enablepassword\r"
        expect "#"
        # Enable configuration mode (terminal)
        send "conf t\r"
        expect "#"
        # Modify VLAN1
        send "interface vlan1\r"
        expect "#"
     # Change VLAN1 Description to Uppercase
        send "description INSIDE\r"
        expect "#"
        send "exit\r"
        expect "#"
        # Save config to NVRAM
        send "wr\r"
        expect "#"
        #Logging out
        send "exit\r"
        expect eof
In the example this works fine for SITE1 passing the credentials SITE1 as the default password and SITE1 as the enable password. I need to do usernames and passwords that are different for each site. I have to make some changes across hundreds of ASA's to terminating tunnels to a new location. Can anyone help out in how to do this, I know I am close I just need it to read, siteA, username, both passwords from a text file, etc

Need help with select that month range with flexible first date

Hello everyone,
I am trying to create a selection of month range (will be in a WITH clause) for a report to display monthly data. But the first month start date can be any date. (Not necessarily the first date of the month)
Examples:
Report input parameters:
Start Date: 08/10/12
End Month: Dec 2012
I was trying to build a with select that will list
Month_Start, Month_End
08/10/12, 31/10/12
01/11/12, 30/11/12
01/12/12, 31/12/12
OR
Month_Start, Next_Month
08/10/12, 01/11/12
01/11/12, 01/12/12
01/12/12, 01/01/13
End month is optional, so if no value the select will list only
08/10/12, 01/11/12

10/10/2012                     01/11/12    But when I try to remove the duplicate period (of the first month) out by restrict rownum, it do not return any rows for the second select at all. The result I get is:
START_DATE                     NEXT_MONTH
10/10/2012                     01/11/12    Can anyone advise what wrong with the select statement ?
Thanks a lot in advance,
Ann

Hi,
Here's one way:
WITH   params      AS
     SELECT     TO_DATE (:p50_start_date, 'DD/MM/YYYY')     AS start_date
     ,     TO_DATE (:p50_end_month, 'DD/MM/YYYY')     AS end_date
     FROM     dual
SELECT     GREATEST ( start_date
           , ADD_MONTHS ( TRUNC (start_date, 'MONTH')
                        , LEVEL - 1
          )               AS month_start
,     LEAST     ( end_date
          , ADD_MONTHS ( TRUNC (start_date, 'MONTH')
                      , LEVEL
                    ) - 1
          )               AS month_end
FROM    params
CONNECT BY     LEVEL     <= 1 + MONTHS_BETWEEN ( end_date
                                  , TRUNC (start_date, 'MONTH')
;:p50_end_month doesn't have to be the last day of the month; any day will work.
If you want to generate a Counter Table containing the integers 1 througn x in SQL, you could say
SELECT ROWNUM AS n
FROM    all_objects
WHERE   ROWNUM <= x
;but, starting in Oracle 9.1, it's much faster to say
SELECT LEVEL   AS n
FROM    dual    -- or any table containing exactly 1 row
CONNECT BY LEVEL <= x
;Also, x can be greater than the number of rows in all_objects.

Columns are

Please help -
The critical part for me, is to display payments not within the date range in 'select expert' statement.
Currenlty my report reflects only payments for FOLDERRSN, where {ACCOUNTBILLFEE.STAMPDATE} in DateTime
(2014, 05, 01, 00, 00, 01) to DateTime (2014, 05, 31, 23, 59, 59) and not other payments outside the date range specified.
Thank you for your time.

Hi Abilash,
This worked !!!
My brother helped me with it here....ofcourse you have intiated the intial idea.
It worked when i used the following SQL at 'Add Command'
Select * from DATABASE_NAME.ACCOUNTBILLFEE A
Where A.FOLDERSN = any ( select B.FOLDERSN from DATABASE_NAME.ACCOUNTBILLFEE B
where B.STAMPDATE >= TO_DATE('20140501', 'YYYYMMDD')
AND B.STAMPDATE <= TO_DATE('20140531', 'YYYYMMDD'))
Excellent support - Thank you so much for your immediate attention and response.
I know, how hard it is to understand someones requirement and suggest solutions.
You are the best and most helpful I have ever come across in my life.
Thank you for your kind heart and extending help to me.

Help with selecting files from script menu or drag and drop

I found this scale images applescript online. It works great when a bunch of files is dragged on top of the script but I would like it to also work when a folder or group of files is selected in the Finder and I activate it from the scripts menu.
I can't get my on run statement to work. I'm not really an Applescript guy so I'm really just asking if someone can help finish what I started in this on run.
-- save in Script Editor as Application
-- drag files to its icon in Finder
property target_width : 120
property save_folder : ""
on run
tell application "Finder"
activate
set folder_path to quoted form of (POSIX path of (the selection as alias))
set theItems to every file of folder_path
end tell
end run
on open some_items
-- do some set up
tell application "Finder"
-- get the target width, the default answer is the property target_width
set new_width to text returned of ¬
(display dialog "Target width:" default answer target_width ¬
buttons {"OK"} default button "OK")
if new_width as integer > 0 then
set target_width to new_width
end if
-- if the save_folder property has not been set,
-- set it to the folder containing the original image
if save_folder is "" then
set save_folder to ¬
(container of file (item 1 of some_items) as string)
end if
-- get the folder to save the scaled images in,
-- default folder is the property save_folder
set temp_folder to ¬
choose folder with prompt ¬
"Save scaled images in:" default location alias save_folder
set save_folder to temp_folder as string
end tell
-- loop through the images, scale them and save them
repeat with this_item in some_items
try
rescaleand_save(thisitem)
end try
end repeat
tell application "Image Events" to quit
end open
on rescaleand_save(thisitem)
tell application "Finder"
set new_item to save_folder & "scaled." & (name of this_item)
end tell
tell application "Image Events"
launch
-- open the image file
set this_image to open this_item
set typ to this_image's file type
copy dimensions of this_image to {current_width, current_height}
scale this_image by factor (target_width / current_width)
save this_image in new_item as typ
end tell
end rescaleandsave

When items are dragged to your script's icon they are passed in to the on open handler, so this triggers:
on open some_items
and the dragged items are passed in as some_items
In contrast, when you double-click on the script, or invoke it via the Script menu, this runs the on run handler:
on run
tell application "Finder"
activate
folder_path to quoted form of (POSIX path of (the selection as alias))
set theItems to every file of folder_path
end tell
end run
However, there's nothing in this block that actually does anything with the selection - you (dangerously) assume that the selection is a folder (you really should check first), and just set theItems to every file in that folder then you exit.
So to do what you want you'll need to edit your run handler to filter the selection and pass files over to the code that does the hard work.
You already have the basis for this - your rescaleandsave() handler, so it's just a matter of identifying the files in the selection and passing those over to that handler:
on run
tell application "Finder"
set cur_selection to (get selection) -- get the selection
repeat with each_item in cur_selection -- iterate through
if class of each_item is folder then -- do we have a folder?
set theFiles to every file of each_item -- if so, get its contents
repeat with each_file in theFiles -- iterate through them
my rescaleand_save(eachfile) -- and process them
end repeat
else if class of each_item is document file then -- do we have a file selected?
my rescaleand_save(eachitem) -- if so, process it
end if
end repeat
end tell
end run
So the idea here is that the run handler gets the selection and works through the (potentially-numerous) items. For each selected item it checks whether its a folder or a file, if its a folder it gets all the files within and passes them to the rescaleandsave handler.
Note that this is not recursive - it won't catch files within folders within folders - since it only looks at the top level of selected folders, but it wouldn't be hard to rework the script to handle that if that's what you need.

Help with Select Decode Round

Hi, If anyone could help me with this. I need to round all these numbers in the DECODE but without repeating ROUND.
This way works:
SELECT title "Title", category "Category",retail "Current Price",
DECODE(category,
'COMPUTER',(ROUND(retail * 1.1,2)),
'FITNESS', (ROUND(retail * 1.15,2)),
'SELF HELP', (ROUND(retail * 1.25,2)),
(ROUND(retail * 1.03,2)))"Revised Price"
FROM books
ORDER BY category, title;
But I need something more like this:
SELECT title "Title", category "Category",retail "Current Price",
DECODE (ROUND((category,
'COMPUTER',retail * 1.1,
'FITNESS', retail * 1.15,
'SELF HELP', retail * 1.25,
retail * 1.03)"Revised Price"),2)
FROM books
ORDER BY category, title;
so that ROUND is not repeated more than once..they all need to be rounded to two decimal places.
any help would be great. Thanks

your second is close. You need to round the decode statement. like this:
SELECT title "Title", category "Category",retail "Current Price",
       ROUND(DECODE(category, 'COMPUTER',retail * 1.1,
                              'FITNESS', retail * 1.15,
                              'SELF HELP', retail * 1.25,
                              retail * 1.03),2) "Revised Price"
FROM books
ORDER BY category, title;Note that the alias (I assume) revised Proce needs to go outside of both the decode and the round.

Help with select function

Well guys, I have a problem here and I didn't find any solutions
So maybe someone of you, can help me!
My problem is:
I have 2 numbers (100 and -200) and I have to plot the greater value.
The problem is for me the signal of -(minus) doesn't means nothing....
For the program I'm making, the -200 is greater than 100
So I tryed put bouth as absolute value, but when I have the "answer" only appears the "200"
and I need it appears -200
So I thought about something like that:
I use a select function and maybe do something like that:
So I have to make something at True or False value at S to make this work!
If true I receive 100, if is false I receive -200
Thanks!

I dont know why is in this section. I posted it on LabVIEW part!
Well Dennis I make it like that:
But now I have a problem
I do the same calc for 3 differents variables like A, B, C
and after that I have to calc which value is the "greater"
But my problem is, If I have the values "-350 300 -400"
the greater will be "300" but for me the "minus" don't mean anything
so I need the greater value is "400"
For all positive values, its works fine!
I compare A and B, after that the greater is compared with C and have a result!
but When I have negative values and positive values... I got that problem...
and When I have only negative values I have a problem too.
"-300 -400 -500" for me the greater value have to be "-500" but labview shows "-300"
because -300 is greater than -500 in algebriac.
And If I use absolute values I will always have a positive value... but I need to know if the value is negative or positive
Anyone, can help me with that?
Thanks

Help with select statement

Hello,
My table looks similar to this, I have removed a few columns:
table1:
Forecast_id Forecast_name Freeze Enabled
100 Q12009 N Y
101 Q22009 N Y
table2:
forecast_id parameter_name parameter_value
100 StartDate 01/01/2009
100 EndDate 03/31/2009
100 Growth % 20
100 Retailer Walmart
101 StartDate 04/01/2009
101 EndDate 06/30/2009
101 Growth % 20
101 Retailer Walmart
What i need to do is
select from table 1, forecast name & freeze
where in table2 parameter = Retailer, Parameter value = Walmart and
Start Date = 01/01/2009 and End Date = 03/31/2009
here is my query is there a easy way this can be done. I have used decode function in the past for similar situation for counting and grouping.
SELECT i.FORECAST_ID,
i.FORECAST_NAME,
i.FREEZE_FLAG
FROM (
SELECT x.FORECAST_ID,
x.FORECAST_NAME,
x.FREEZE_FLAG
FROM (
SELECT A.FORECAST_ID,
A.FORECAST_NAME,
A.FREEZE_FLAG
FROM GC_FORECAST A, GC_FORECAST_PARAMETERS B
WHERE A.FORECAST_ID = B.FORECAST_ID
AND B.PARAMETER_NAME = 'Retailer'
AND B.PARAMETER_VALUE = 'Walmart'
) x, GC_FORECAST_PARAMETERS y
WHERE x.FORECAST_ID = y.FORECAST_ID
AND y.PARAMETER_NAME = 'StartDate'
AND y.PARAMETER_VALUE = '01/01/2009'
) i, GC_FORECAST_PARAMETERS j
WHERE i.FORECAST_ID = j.FORECAST_ID
AND j.PARAMETER_NAME = 'EndDate'
AND j.PARAMETER_VALUE = '03/31/2009';
Thank you for your time and help.

Need help with Telnet command in JSP

Here is the code I have been working on but it will not display the buffer to the page..
String [] cmd1 = {"cmd.exe","/c","telnet hqsun1.xx.xxxxx.com"};
          Process n;
          String T = "" ;
          n = Runtime.getRuntime().exec(cmd1);
          BufferedReader in1 =
          new BufferedReader(new InputStreamReader(
          n.getInputStream()));
          while((T=in1.readLine()) != null)
          out.println(T+"");
Maybe someone has done this before? I am trying to acomplish a telnet net session to the screen with some exicuted commands, because this tool is going to be used to help determine system status when the help desk needs to check on something.
Thanks

I don't want to be discouraging, but I'm not quite sure you've thought the problem through. You say that you'd like to create a web page capable of providing various pieces of information to the help desk, and you suggest ping and the output of various canned telnet commands as examples.
What is preventing the help desk from just executing those commands at the command prompt?
I realize that the people working the help desk are (ahem) there for a reason, but it is really much faster for me to just simply type "ping www.mpalfrey.com" at the prompt, then it is for me to fire up the web browser and wait for a response that way. You will likewise find that it is a lot more convenient to perform diagnosis on remote machines directly from the command prompt.
Uh, it's kind of like giving someone a screwdriver, then saying, "oh wait a second" and making them wear an oven mitt in order to use the screwdriver.
But, if you really want to do it this way, the best thing to do is create a wrapper class that directly calls the system command and captures the output to a stringbuffer. Then your JSP page simply has to clone that wrapper via a new() command and trigger it if you go the singleton route. The code would look something like this...
<%@ import page="com.mpalfrey.shellcommands.ping" %>
<%
   myPing foo = new myPing( request.getParameter( "victim" ) );
   foo.trigger();
%>
Ping results:
<%=foo.results()%>JSP can do a lot of wonderful things, but that doesn't mean you have to do it that way. :)

Need help with IOS commands to see wireless printer

Seems that I'm not asking the question correctly, or providing the right information.
The problem:
I've purchased a wireless printer, (an HP 6500a) and I can not see / ping / use the printer on the wireless network.
Environment:
Cisco 891 ISR in standalone. Single office - Home-office environment. Nothing spectacular. WLAN connected and operational to the internet.
The printer is configured to use a static IP of 10.0.0.3 and reports that it is connected to the AP. However, when I ping FROM the command line at the AP, I DO NOT see the printer. (I did previously, but we lost power last night due to a storm and I'm still trying to reconfigure it...) DHCP is configured on the router to exclude the range 10.0.0.1 through 10.0.0.99
How do I configure the wireless router to allow any connected client to share files / printers etc? Seems that the Cisco router has this shut off
by default and I've found nothing in the user manual or by asking for help on here how to reverse this so that I can share printers / files on the LAN.
Please, I'm not stupid, but I'm only casually familiar with IOS and Cisco's networking terms.
Thanks in advance,
-Mike

Default username/password setup on AP is cisco/cisco with privilege level 15.
It is strongly suggested that you create a new username with privilege level
15 using the following command for console security.
username <myuser> privilege 15 secret 0 <mypassword>
no username cisco
Replace <myuser> and <mypassword> with the username and password you want to
use. After you change your username/password you can turn off this message
by configuring "no banner login" and "no banner exec" in privileged mode.

Wireless clients can get on w/o issue. Nobody can ping anyone else or see them.
No file sharing, no printer.
Tried using the web-based config which works for some items, but wont access the advanced config.
I'm on my way into town, so can't post the router config, but it is posted in my earlier question
of last week. I can login later if you otherwise need it here.
Thanks,
