Use ODBC toread and write spatial data

Does anyone have an example of using ODBC to read and write geometry objects from and to Oracle9i with Oracle Spatial?

hi ,
you cannot read geometry with odbc you have to use oo4o(oracle object for ole)
here a sample code :
Private Sub mnu_test_Click()
Dim OraSession As OraSession
Dim OraDatabase As OraDatabase
Dim LRS As OraDynaset
Dim Ordinates As OraCollection
Dim sdo_geometry As OraObject
Dim i As Integer
Set OraSession = CreateObject("OracleInProcServer.XOraSession")
Set OraDatabase = OraSession.DbOpenDatabase("n12dev6", "gis/spatial", ORADB_DEFAULT)
Set LRS = OraDatabase.CreateDynaset("select * from GPS_LRS where id ='11SR012001'", ORADB_DEFAULT)
Set sdo_geometry = LRS.Fields("geometry").Value
Set Ordinates = sdo_geometry.Item("sdo_ordinates").Value
'access all elements of the SDO_ORDINATES VArray
For i = 1 To Ordinates.Size
MsgBox Ordinates(i)
Next i
End Sub
hope this helps

Retrieving spatial and non spatial data in one query

Hello. I am having slight difficulties using JDBC to retrieve both spatial and non spatial data in the same query. The following is code from a sample program of mine that retrives spatial data from spatial tables.
(In spatialquery geom is a geometry column and city is simply the name of the city):
try
Geometry geom = null;
String database = "jdbc:oracle:thin:@" + m_host + ":" + m_port + ":" + m_sid;
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
con = (OracleConnection)DriverManager.getConnection(database, sUsername, sPassword);
GeometryAdapter sdoAdapter =
OraSpatialManager.getGeometryAdapter("SDO", "8.1.7", STRUCT.class, null, null, con);
String spatialquery = "SELECT a1.geom, a1.city \n" +
"FROM cities a1";
Statement stmt = con.createStatement();
OracleResultSet rs = (OracleResultSet) stmt.executeQuery(spatialquery);
int i = 0;
int noOfFeatures = 2;
while (rs.next())
for(i = 1; i <= noOfFeatures; i++)
STRUCT dbObject = (STRUCT)rs.getObject(i);
try
geom = sdoAdapter.importGeometry(dbObject);
catch(GeometryInputTypeNotSupportedException e)
System.out.println("Input Type not supported");
catch(InvalidGeometryException e)
System.out.println("Invalid geometry");
System.out.println(geom);
}//end while loop
This retrieves the sptial data fine, however when I attempt to retreive the non-spatial data I keep getting a "ClassCastException" error. I understand it is something to do with "STRUCT dbObject = (STRUCT)rs.getObject(i);" line. Can anyone tell me how to retrieve both spatial and non-spatial data in the one query using JDBC. I have tried nearly everything at this stage. Cheers joe

Is there a way to use the FF vi's to read and write complex data types; specifically, clusters?

I'm trying to interface with a Fieldbus device through LabVIEW. I need to be able to read and write a variable that consists of a cluster of two unsigned int 32's. The FF vi's provided with FF Communications Manager 3.2 do not support clusters. I have tried to use a code interface node to write my own, but the CIN's I was using before to do this function do not give me a device list anymore (they were originally written on Communications Manager 2.3.5). I have recompiled the .lsb, as well as trying to use the older versions of the header and library files. Is there another workaround I can use?

Hello Bryan,
The BrowseDeviceList VI was released within NI-FBUS 3.2. For NI-FBUS Configurator 3.1, please unzip the attached file and copy the "addon" and "Ff" folders into "\vi.lib" directory. LabVIEW 7.1 or above version is required for using these addons.
And for your information, there is a free upgrade (version 3.1.1) for NI-FBUS Configurator 3.1 users. Here is the link to the upgrade kit.

What is the fastest way to record and write image data?

Hello,
I am new to labview and am using the IMAQ software package to record and write data from a CCD camera to the hard drive. The end goal is a program that records and saves as much data as possible as quickly as possible, for experiments lasting on the scale of days. I have been experimenting with the snap, grab, and sequence methods of recording. To save the image data I was told by NI customer support that TDMS streaming would be the fastest method. I have also been experimenting with the TDMS VIs, however I have found the IMAQ Write File 2 VI to be faster in practice. Am I doing something wrong with the TDMS file structure? Is there a more efficient way to convert IMAQ image data to a dataform that can be written as TDMS? I am posting two of my programs to provide a clearer example of what I am trying to do. The first takes a snap of the image and appends it to a TDMS file. The second is the fastest I have found so far and uses Grab to record the images and the IMAQ Write File VI to save them.
Thanks

Hi
For me it is no surprise that the second VI is faster then the first one, the reason is you can not compare this two VI with each other.
In the first VI you work with TDMS files, in the second with png files. That would be much faster, because TDMS files need a lot of diskspace.
Second point, why do you open, write and close for eacht iteration of the for loop a TDMS file in your first VI? That need really a lot of resources, so it coudn´t be fats as well.
Save your converted pictures in one array, an after the acquisition you can save it in one TDMS file. When you need for each picture a TDMS file you have to know that this need some time to do this.
So now for the architecture of your first VI, please look to the LL Sequence.vifrom the examples (C:\Program Files\National Instruments\LabVIEW 8.6\examples\IMAQ\IMAQ Low Level.llb\LL Sequence.vi), there you can see how an acquisition of a number of images have been to do.
When you like it really fast, you make a producer/consumer architecture (see examples in LabVIEW for that).
So in the first whileloop you acquire the images, write into a queue and in the second, parallel whileloop you read the queue and save the images. (see attachment)
Hope that helps
Kind regards

How do I read from a text file that is longer than 65536 lines and write the data to an Excel spreadsheet and have the data write to a new column once the 65536 cells are filled in a column?

I have data that is in basic generic text file format that needs to be converted into Excel spreadsheet format. The data is much longer than 65536 lines, and in my code I haven't been able to figure out how to carry over the data into the next column. Currently the conversion is done manually and generates an Excel file that has a total of 30-40 full columns of data. Any suggestions would be greatly appreciated.
Thanks,
Darrick
Solved!
Go to Solution.

No need to use nested For loops. No need for any loop anyway. You just have to use a reshape array function. The picture below shows how to proceed.
However, there may be an issue if your element number is not a multiple of the number of columns : zero value elements will be added at the end of the last column in the generated 2D array. Now the issue depends on the way you intend store the data in the Excel spreadsheet : you could convert the data as strings, replace the last zero values with empty strings, and write the whole 2D array to a file (with the .xls extension ) using the write to spreadsheet function. Only one (minimal) problem : define the number of decimal digits to be used;
or you could write the numeric array directly to a true Excel spreadsheet, using either the NI report generation tools or ActiveX commands, then replace the last elements with empty strings.
We need more input from you to decide how to solve these last questions.

TimesTen and Geo-spatial data

Can TimesTen support geo-spatial data (and datatypes) as supported in Oracle? For example, if one created a set of Oracle tables that held geo-spatial data, could TimesTen be used in its "caching" form to speed geo-spatial queries?
Thanks!
--rick grehan

No, sorry. TimesTen does not support Geo-spatialo datatypes or functions.

How to use global classes and display returned data?

Hello experts,
I have the following code in a program which accesses a global class (found in the class library). It executes one it's static methods. What I would like to do is to get hold of some elements of the returned data. How do I do that please?
Your help is greatly appreciated.
***Use global class CL_ISU_CUSTOMER_CONTACT

How can I do this please?

I now have the following code. But when I check for syntax I get different error. They are at the end of the list.
Here is the code the way it stands now:

Here are the errors I get:
The field "DREF" is unknown, but there is a field with the similar name "OREF" . . . .
When I replace itr by OREF I get:
"OREF" is not a data reference variable.
I then try to change it to dref_tab. I get:
"DREF_TAB" is not a data reference variable.
Any idea? By the way, must there be a HANDLE event for this to work?
Thanks for your help.

Read the file and write the data into string or int

Ok, here's another rookie question.
I got to read the line from the file and store it in the memory as string or integer.
I wrote this code:
File inputFile = new File("c:/xxx.yyy");
String outputString = new String();
FileReader c1 = new FileReader(inputFile);
StringWriter d1 = new StringWriter(outputString);
int data;
         while((data = c1.read()) != -1)
             d1.write(data);
             System.out.println(data);
         c1.close();
         d1.close();This is how I see it, but it cannot be even compiled because there is no such thing as StringWriter(String) wich I find completely irrational. So tell me, am I retarded or what? No, but seriosly, please help the newbie to understand these streams, am I supposed to use some kind of buffer? Any help appreciated.

A String is an immutable. You cannot update a String.
A new String() is basically the same as an empty String ""
An empty StringWriter can be created with new StringWriter().
If you use a BufferedReader you can call readLine().
BufferedReader in = new BufferedReader(new FileReader(filename));
String line;
while((line = in.readLine()) != null) {
System.out.println(line);
}

R N V Prasad

Hi
I am first uploading file and if the file is more than 2MB, i am compressing it. i used the below method for compressing.
public void zipFile(String inputFilePath,String outputFilePath,String outFileName){
long fileSize;
long twoMBFileSize=2097152;
String outFileLocation;
try
byte[] data = new byte[1000];
File file=new File(inputFilePath);
FileInputStream fis=new FileInputStream(file);
BufferedInputStream in = new BufferedInputStream(fis);
fileSize = file.length();
System.out.println("File size.."+fileSize);
int count;
outFileLocation=outputFilePath+outFileName;
System.out.println("outFileLocation..."+outFileLocation);
ZipOutputStream out = new ZipOutputStream(new BufferedOutputStream(new FileOutputStream(outFileLocation)));
out.putNextEntry(new ZipEntry(outFileName));
while((count = in.read(data,0,1000)) != -1)
out.write(data, 0, count);
in.close();
out.flush();
out.close();
catch(Exception e)
e.printStackTrace();
And i will read the compressed file and posting to DB.
Here i am facing the problem while downloading the compressed files.

How to open MSWORD using JAVA/JNI and write the database entries into WORD

Hi..
I am searching for java codes that uses JAVA NATIVE INTERFACE (JNI) for opening MSWORD 2003.
To be brief.
I created HTML form called Employee_data.
if i click on Submit button a word document should be opened.This should be using JNI.
I have also created a servlet in jsp to process the form data and store it into database(mysql).;
Please help me to find the codes to open MSWORD on submit click and to write the database entries into word file.Can i get the full code for that.This is so urgent.
Thanks in advance.

Hi Suresh,
The easest solution I can think of is to copy the math equation from the PowerPoint then paste in the Word document directly, there's actually no way to convert it to plain text, some equation is very complext, String variable is not suitable in this case.
For example, this code works fine:
var powerPoint = new Application { WindowState = PpWindowState.ppWindowMinimized };
var oPresSet = powerPoint.Presentations;
Microsoft.Office.Interop.PowerPoint._Presentation oPres = oPresSet.Open(@"C:\test.pptx", MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse);
var strObj = oPres.Slides[1].NotesPage.Shapes[2].TextFrame2.TextRange.MathZones.get_MathZones();
strObj.Copy();
Microsoft.Office.Interop.Word.Application wordApp = new Microsoft.Office.Interop.Word.Application();
wordApp.Visible = true;
Microsoft.Office.Interop.Word.Document doc = wordApp.Documents.Add();
doc.Range(0, 0).Paste();

How do I query a SharePoint List using a url and filtering on date?

I am reading a SharePoint list using jquery. Everything is working fine
except for the filter. Each list item has an expiration date. I want to retrieve JUST the items that have not expired (Expires > Today) but I can't figure out the url syntax and I've been searching all day for an example and
can't find one. Could someone please help?!? See bold code below.
Thanks,

$(document).ready(function ()

$.each(results.d.results, function (i, mmAlert)
itemID = mmAlert.Id;
mmTitle = mmAlert.Title;
mmClass = mmAlert.ClassValue;
//alert("Item="+itemID+" Title="+mmTitle+" Class="+mmClass);
AddMMStatus(mmAlert.Id,mmAlert.Title,mmAlert.ClassValue);

Fadi,
Thanks for your response. I actually have another version of the code that uses the SP client objects that works. The problem is site boundries. Let me give a more complete project explanation.
I am creating a master page for a new intranet. As part of this master page, I want to read from an SP list of alerts and post each alert (if not expired) in the SP status bar. I've gotten this to work with SP client objects and jquery (except
for the date filter part). Both of these solutions work fine on the top site level. BUT when trying it out at the sub-site level, the SP client objects version of my code fails. The jQuery version works except the date filtering.
I looked at the example from your link and it looks like a bit of a hybrid to my approaches: JQuery with CAML. My question is; does this example permit me to access a list in the top-level site from the subsites? Please excuse my ignorance,
but I am an EXTREME newbie in this having spent the past 8 years as a VB.Net developer and a little bit of ASP.Net.
Below are the two different versions of my code in different versions of my master page definition:

How can I move and replace spatial data to other table ?

Hello,
I have a Global Map table1 and other Local Map on table2, Their scale is 1:100000 and 1:5000 .
Now I want to move and replace table2 into table1 , make the new map look without gap
how can i do ?

Hi Yacus,
You have 2 different scales. In my opinion you should NOT use both in one table because the data quality may be different!
You want to insert your table2 data into table 1? This without problem. But when you try to test for identical geometry parts you will not succeed, because of generalization from 1:500 to 1:100000.
Can you exactly describe, what you want to do (which data, what to achieve)..
reghards, Andreas

How to add in ODBC connection and configuration for data connection

Hello expert,
on my computor, there is a oracle client for oracle 10g. now there is new oracle 11g installed , I want to create a ODBC connection to this new database. but when I create ODBC , I can't find server type for oracle 11g , there only has driver for oracle 10g. will you please tell me how to create ODBC for this new DB? will you please tell me where is the configuration file for data source on my computor?
Many Thanks,

Many Thanks,So, on this machine you have
- Oracle 10g client (only), and in a seperate ORACLE_HOME
- Oracle 11g rdbms
First, the 10g client will connect quite well to the 11g database
Second, the 11g database includes the basic client admin software, but the odbc drivers are not installed by default. You have to run OUI and choose 'custom' installation, then select 'windows components' from the list of available components.
I've never wanted to install the odbc driver as part of the database installation. Only on remote client installations.
What are you really trying to achieve?

Use ODBC toread and write spatial data
