Getting info out of an excel file like a database

Hi,
The problem i have is that i have to get info out of an excel file like a database. So i have to be able to perform a kind of query, but to an excel file. Is this possible?
lay-out excel file:
number | request | chemical composition
| | C | Mn | Si | ....
125654 | |0.20%|0.10%|0.05%|.....
i should have to be able to search on the number and read the differend % (C, Mn, Si). This % are used in a formula to calculate a value that is used for DAQ
I can do this action with an acces DB, but not with excel. The problem is that they used excel for some years now (where i work) and changing the excel file to a DB would be a very long w
ork.
If someone could help i'd appreciate it
thx

I tried it like you said, but i get the error: -2147217865
exception occured.
[Microsoft][ODBC Excel Driver] The microsoft jet database engine could not find the object 'Sheet1'. Make sure the object exists...
So he doesn't seem to recognize a datasheet as a table (if i may compare it like this) when i choose the microsoft Excel driver with the workbook as described in your answer.
Any ideas?
i putted some attachements, maybe they make it easier to understand

Uses the library to get UTL_FILE to read a excel file in PL SQL?

Good day.
Someone can give me some code that uses the library to get UTL_FILE to read a excel file in PL SQL?
I intend to use this library because I want to run a script on my machine to treat an excel file without having to make changes on the server.
Thank you.

Ranit's links are useful, you should read them.
Also check out the FAQ on this forum:Re: 5. How do I read or write an Excel file?
UTL_FILE is not the best choice for reading data from Excel files.
It also will not be able to read an Excel file located on your client computer. As with any PL/SQL code on the database, it can only access things that the server itself can see, so that doesn't include hacking across the network, bypassing network security, and hacking into the client computers operating system to read files directly from it's hard disk. This isn't how client server architecture is intended to work.

I can't download Ikea 3D kitchen planner. It's really frustrating - a message is appearing on my mac book pro that I ned to get info and check that various files are unlocked. I've checked that all other requirements are fulfilled, still won't download

I can't download Ikea 3D kitchen planner. It's really frustrating - a message is appearing on my mac book pro that I ned to get info and check that various files are unlocked. I've checked that all other requirements are fulfilled, still won't download. Any help very gratefully received. Thank you.

Hi, I'm not really very good with computers and am having the same problems when trying to install the Ikea 3D kitchen planner, please could you take me through the steps?
1. Download (save) the disk image file 2020PluginInstaller.dmg
I double click on the link which says "Install 3D Planner"
I agree to the t&cs
A file downloads to my download folder called 2020PluginInstaller_IKEA.dmg
2. Mount the disk image (open/run the downloaded file) if not mounted automatically
I double click on the downloaded file
3. Find the 2020PluginInstaller window (might be behind the window on top)
A small window opens up with a lego brick called 2020PluginInstaller_IKEA.dmg and a folder called Internet plug ins. I highlight the lego brick and do File, Get info and unlock it
4. Drag the lego piece to the folder (if you do not have admin privileges you will be prompted to authenticate)
I do this and put in a password to authenticate
5. Restart the browser (it is not enough to close the browser window, you need to restart the browser
application)
I've tried restarting Safari, I've tried re-starting the computer
6. Access the same link and you will now see the Start button and be able to start planning your room!"
When I go back to the IKEA kitchen planner I don't see a start button, I just see the exact same screen as before prompting me to install the 3D planner
Please can you help?

Problems by getting info out of XML file with a HTTP request

Hi,
I have a litte question. I'm working on an application that works together with google maps. In my java code, I get general information about address out of one database table, and I want to add some geographic information like coordinates that I want to retrieve from Google Maps through HTTP:
Right now my code is like:
while (resultSet.next())
                         title = resultSet.getString("title").replaceAll("'","''").toUpperCase();
                         author = resultSet.getString("author").replaceAll("'","''").toUpperCase();
                         location = resultSet.getString("location").replaceAll("'","''").toUpperCase();
                         straatnaam = resultSet.getString("straatnaam").replaceAll("'","''").toUpperCase();
                         nummer = resultSet.getString("nummer");
                         landcode = resultSet.getString("landcode").replaceAll("'","''").toUpperCase();
                         address = straatnaam + " " + nummer + " , " + location + " " + landcode;
                         url = "http://maps.google.com/maps/geo?q=" + address + "&output=xml&key=+key+";
                         String query = "INSERT INTO data2 VALUES ('" + i + "','" + title + "','" + author + "','" + resultSet.getString("date1") + "','" + resultSet.getString("date2") + "','" + location + "','" + resultSet.getString("postcode") + "','" + straatnaam + "','" + resultSet.getString("nummer") + "','" + landcode + "','+something like url.getCoordX+','something like url.getCoordY')";
                         success = sql2.executeUpdate(query);
                         i++;
Now I don't know how I can handle that. Is it possible to do an HTTP request in Java without using Java Script of servlets? I just want to get the X and Y coordinates out of the XML file.
The XML file will be something like:
<kml xmlns="http://earth.google.com/kml/2.0">
<Response>
<name>1600 amphitheatre mountain view ca</name>
<Status>
<code>200</code>

many greetings and thanks in advance

Hi, sorry for being not so clear. My question was actually if it is possible to do a HTTP request in Java without using servlets or being in Java Script. Actually my question was more specific for Google maps, because it didn't seem to work. It was my mistake, and already solved, to forget to make the webservice-call "URL-encoded". Because of that, I always received a HTTP 400 error, and that's why I thought it wouldn't be possible.
But now I have another, perhaps for you guys stupid question. The result I get from the webservice URL is of the form:
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.0">

</kml> Now I want to get the value of the coordinates field.
This is my code:
address = URLEncoder.encode(address, "UTF-8");
urlString = "http://maps.google.com/maps/geo?q=" + address + "&output=xml&key=ABQIAAAA9fEXNK-q6vKpPU0JCmPPkxQjbVBpjtblJJYkDfbMo0e51afwehRmujfvBtJqx1Qehg6e6QgCRY8poA";
url = new URL(urlString);
XPath xPath = XPathFactory.newInstance().newXPath();
Document domDoc = processData(url);
path = "/kml/Response/Placemark/Point/coordinates";
coord = xPath.evaluate(path, domDoc);
System.out.println("coord : " + coord);Now, in the last line, by writing out the value of coord to my screen, I get the value "1", instead of "4.126295,51.097724,0" I would expect, anyone knows what I'm doing wrong?

How to get data from an existing Excel file using report generation toolkit

I'm trying to use the Excel Get Data vi from the report generation toolkit, but i can't figure out how to turn a browsable path into the right type for the VI. I've tried using the New Report.vi, but that doesn't work unless you use a template. It won't open an existing excel file and make it an open report to pull data from.
Essentially, i have a bunch of excel files that have data in them and i want to use a VI to analyze the data. So, i'm trying to pull in all the data directly from the excel file so i don't have to reproscess them all into text so i can use the more standard spreadsheet VIs. But to even convert the excel file programtically in labview won't i still need to be able to open the excel file and get the data?
Solved!
Go to Solution.

I C.
Got it,
the reason why I can view it using my Excel file because its in .CSV.
I open Microsoft Excel to open .CSV file.
But you can also open .csv file with notepad.
So, you cannot open .xls with Read Spreadsheet File

Connecting an excel file as a database source in crystal

Hi
I have crystal 2011 on my pc and I can easily access information in an excel file by connecting it as a data source.
However, when i copy the excel file onto the SAP server and try to connect to the excel file there, it connects ok
but there is only displays Add Command and i can access Final Budget Table.
I know it is probably a simple issue but i cant seem to see it.
The server is using crystal 2008 and does not have excel installed.
The excel file has been into the same folder the report exists in.
I will eventually want to run this report through Inforview, what way does that work with regards the excel file?
Thanks
Rachael

Manupulating Excel File Stored In Database

Is there any way I can manipulate the excel file that is stored in the database as LONG RAW ?
I need to allow user to manupulate the excel file that is stored in database and accordingly fetch the specific data from that manipulated Excel File of Database.

Your best bet is to keep the data in tables and generate a new excel file each time. Search this forum on how to generate excel files.. Here are three techniques... I like the XML method..
1) OLE2
2) XML
3) CSV
I have also done this using webutil..
1) retrieve excel blob from db to client using webutil function db_to_client_with_progress()
2) manipulate excel file on client using CLIENT_OLE2
3) put excel file back in db using webutil function client_to_db_with_progress()
Sorry.. Just re-read your post and didnt notice the Long-raw part.. :)

"get info" not recalculating "size" field in iTunes XML database correctly

I have updated some of my mp3 files directly in the iTunes directory. The update changed from CBR to VBR at a higher bit rate. I selected the files and used 'get info' to update the iTunes database with the new bit rate information, which seemed to work fine. The resulting update works fine on the 1G nano, the 3G nano and the 1G iPod (yes, 1G!), but does not work on the iPod 5G (Video 80Gb). On the 5G iPod the changed songs will play for about a minute, then jump to the end of the song.
After much investigation, I found that deleting the song from iTunes and re-adding it solved the problem. When I examined the iTunes database had a different value for the size field. It went from
<key>Size</key><integer>4969036</integer>
to
<key>Size</key><integer>4967106</integer>
There are other changes, but this seems to be the most significant.
Is there any way to force iTunes to re-calculate this field?
Thanks,
Jonathan
PS I will post this on the iPod forum as well.

My own experience with truncated songs on the iPod is that I flag them when they happen. When I get back to iTunes, I resync and pull up the recently played and find those songs. Note the time, which is usually shown as the abbreviated version. If I then double click them to play, iTunes will normally update the time to the correct time. Resyncing to the iPod fixes the problem.
Oh I should mention that I give truncated songs on my iPod a 3-star rating as a tag. So after I "re-play" the song on iTunes to fix the time, I then change the rating back to no-stars. So this also forces an update back to the iPod. So you might have to tweak something after fixing the time to get it to reupdate back to the iPod.
