How to create a buffer by passing a just polygonpopints as a parameter
hi ,
this query about oracle spatial...
please tell me how to create a buffer around a single polygon data.. by passing single polygon co-ordinates as a
parameter..
ex: for a point the following works..
select * from TEMIS where SDO_INSIDE(TEMIS.GEOMETRY ,SDO_GEOM.SDO_BUFFER(SDO_GEOMETRY(2001,32643 ,SDO_POINT_TYPE(70.21931,10.32379,NULL),NULL,NULL),10,0.00000005,'UNIT=KM') )='TRUE'
i want it for a plygon data

Welcome to the SQL and PL/SQL forum.
It would be helpful to us if you post:
- your database version
- an example of what you want, a small dataset to work with in the form of CREATE TABLE + INSERT statements ideally and the results you want from that.
¿What are polygonpopints?
Related to http://en.wikipedia.org/wiki/Point_in_polygon perhaps?
If your question is Oracle Spatial related, then please refer to the Spatial Forum @ Spatial

How To create a Buffer Application Program in LabVIEW?
Dear all:
Can someone advise me on how to implement a buffer application for LabVIEW.
Basically I have 2 application programs than run continously in paralell.
1) LabVIEW Data Logging & Plotting Program. It takes 90 ms to excute its code
2) C++ Data Acquisition Program. It Samples the data from a Reflective Memory Card (on the PCI bus of my PC)
at 1ms and creates a Buffer where it store one sample per channel every 1 ms.
I know LabVIEW have the Code Interface Node to call a C program but since both (The LabVIEW and the C) are runing (one slower than the other) in Parallel I need to somehow interrupt the C program from LabVIEW and get from it the data that it as collected so far.
Any suggestio
n will be highly appreciated. I attach txt file with a little more description of the problem.
Thank You very much.

NI_SW_Buffer_Question1.txt 2 KBHi Felix,
The best architecture for this application would be to have the C++ program divided into two threads. One thread is continuously acquiring data and placing it in a queue. The other "handling" thread will read data from the queue and serve it up to your LabVIEW application.
Much better than using the Code Interface Node, build the C++ application into a DLL. You can then call a function from your LabVIEW program to start the acquisition, and then calls to the handling thread function will return data to LabVIEW.
I hope this helps.

I develope a porgramm for continious monitoring. If the voltage of a channel exceeds or is lower than the upper or lower limit of tolerance the actual date must be stored and additionally the dates being stored 10sec before and after this event. Can somebody give some advice how to create the buffer to keep the dates 10s before the error event? Thank U.
I've written you a quick array buffer vi. I'm not sure if it'll be fast enough though.. Try it and see! I've used the loop numbers in my array, but i'm sure you can feed in the dates instead.

There is an excellent book which can be bought from Amazon. The following link show some content. Have a look at Chapter 9 on page 305 for discussion of BUFFER and polygons.
http://books.google.com/books?id=-ZDAcf-h3VgC&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false
This code details a polygon:
MDSYS.SDO_GEOMETRY(

81989,
NULL,
MDSYS.SDO_ELEM_INFO_ARRAY(1,1003,1),

How do you create a buffer of a geometry in SQL Server 2012?
Hello,
I am new to SQL Server 2012 and spatial data. I built a geometry object of coordinates from a polygon that I stored in a database. The code is below:
DECLARE @digb GEOMETRY;
SET @digb = GEOMETRY::STGeomFromText('POLYGON ((-79.927138 40.362654, -79.91883 40.364224, -79.915966 40.361067, -79.917897 40.359266, -79.927398 40.360142, -79.927138 40.362654))', 4269);
I am using SRID 4269 (Latitude/Longitude NAD83). I have no issues getting this geometry to load properly when the query is executed. (shown below)
My problem is that I am unable to create a valid buffer of 150 feet on this geometry. I have tried using these 3 statements below (I assumed BufferWithCurves() would be the one that would work); however, ALL of them returned to an invalid buffer of
the polygon (shown below):
- DECLARE @digbb GEOMETRY = @digb.STBuffer(2);
- DECLARE @digbb GEOMETRY = @digb.BufferWithCurves(2)
- DECLARE @digbb GEOMETRY = @digb.BufferWithTolerance(@BufferSize,250.0,1);
Does anyone have any idea of how creating this buffer of a geometry object (polygon mentioned above) in SQL Server 2012?
Thanks in advance for any help.
NickHi Nick,
BTW, please do ask questions on the forum, that's what it's for. I only meant "if my explanation in that specific answer was unclear, let me know and I'll clarify". Feel free to start a new thread for each topic because that way, it's
might be easier for folks to search on.
Specific answers:
I haven't worked directly with the MapInfo loader but if you're working with SQL Server, I assume what they may be doing is looking for "geodesic SRIDs" that SQL Server supports (the ones listed in sys.spatial_reference_systems) and loading those
as geography, else geometry. That may be a good thing to do.
If you want to decide yourself, here's some (short) background.
Only SQL Server (I think PostGIS might have added it) has separate geography and geometry types. Everyone else always uses "geometry" and gives you (maybe) the ability to convert between SRIDs in the database. SQL Server doesn't have
this built-in; you'd need to use a library like PROJ4.
You can use geometry type to refer to geodesic SRIDs, but it doesn't have a way to "take the area using spatial instances in decimal degrees and come up with meters". So, if you only use it to display on a map, it will display correctly.
Or close enough. Same with intersects, intersection and the like. But anything like area, distance, or, in your case buffer using a specific number of meters, you need to use geography. You could have gotten somewhat similar-looking
results with geometry by making your input to STBuffer a sufficiently small fraction, but it would be a guess on your part, not a "150 feet" buffer.
You can't CAST/CONVERT between geometry and geography because they didn't want people to assume that these would do SRID conversion. However, there is a codeplex library "SQL Server Spatial Tools" (http://sqlspatialtools.codeplex.com/) that
has two methods: VacuousGeometryToGeography and vice-versa, that does the equivalent (but optimized) of taking one type, spitting it out in well-known text format, then using it to initialize the other type. Or you can do this in your own code.
In general, geography is for anything geodesic; geometry is for planar or projected coordinate systems (e.g state plane coordinate systems in US, that don't use Long/Lat). But geography is slightly slower in calculations (like intersects) because it's more
complex than simple Euclidian geometry. And folks in other platforms are used to using "geometry" and having the platform do the (sometimes fairly expensive) conversions on-the-fly. Or maybe you don't care about the area, distance, etc.
Even in the geography type, WKT specifies (Long Lat) not (Lat Long). This is because the OGC standard doesn't distinguish and calls things (X Y), and if you think about it, (X Y) is (Long Lat) not (Lat Long). The SQL Server geography-specific method MakePoint
has latitude first as a parameter. OGC or SQL/MM standard methods and property names start with "ST" in SQL Server (e.g. STIntersects); SQL Server-specific methods and properties do not (e.g. MakePoint, ReorientObject).
Finally, attempting to do spatial calculations with unlike SRIDs (e.g. intersects between SRID 4269 and 4326 instance) returns NULL.
One more post coming on this thread with some info/links.

How to create pass-through-proxy?
How do I create some kind of pass-through proxy that can listen and receive OCI, and then forward the commands to the oracle database (sometimes where the SQL is slightly altered). What is the best way to do this?
I failed to find any relevant help in the docs. :-(
Thanks in advance!Anyone? I guess what I'm looking for is how to receive instead of just sending OCI commands, and extract the SQL from the received OCI commands/packages for possible modification/refactoring.

How to create an XML document from a String.
Can anyone help,
In the Microsoft XML Document DOM there is a load function load(string) which will create an XML document, but now we are switching to Java and I do not know how to create and XML document from a string, this string �xml document� is passed to my program from a webservice and I need to read several xml elements form it in a web server.
This string is a well formatted XML document:

<Countries NumberOfRecords="1" LanguageID="en-us">
<Country>
<CountryCode>AU</CountryCode>
<CountryName>AUSTRALIA</CountryName>
</Country>

I made it work using:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
factory.setIgnoringComments(true); // We want to ignore comments
// Now use the factory to create a DOM parser
DocumentBuilder parser = factory.newDocumentBuilder();
//TransformThisStringBuffer is a string buffer wich contain the 'XML document (String)'
InputStream in = new ByteArrayInputStream(TransformThisStringBuffer.toString().getBytes());
// Parse the InputStream and build the document
Document document = parser.parse(in);
But which one is faster InputSource or InputStream, were would you put the "new InputSource(new StringReader(yourString))" in the above code? -

How to create a report based on a DataSet programatically
I'm working on a CR 2008 Add-in.
Usage of this add-in is: Let the user choose from a list of predefined datasets, and create a totally empty report with this dataset attached to is. So the user can create a report based on this dataset.
I have a dataset in memory, and want to create a new report in cr2008.
The new report is a blank report (with no connection information).
If I set the ReportDocument.SetDataSource(Dataset dataSet) property, I get the error:
The report has no tables.
So I must programmatically define the table definition in my blank report.
I found the following article: https://boc.sdn.sap.com/node/869, and came up with something like this:
internal class NewReportWorker : Worker
public NewReportWorker(string reportFileName)
: base(reportFileName)
public override void Process()
DatabaseController databaseController = ClientDoc.DatabaseController;
Table table = new Table();
string tabelName = "Table140";
table.Name = tabelName;
table.Alias = tabelName;
table.QualifiedName = tabelName;
table.Description = tabelName;
var fields = new Fields();
var dbField = new DBField();
var fieldName = "ID";
dbField.Description = fieldName;
dbField.HeadingText = fieldName;
dbField.Name = fieldName;
dbField.Type = CrFieldValueTypeEnum.crFieldValueTypeInt64sField;
fields.Add(dbField);
dbField = new DBField();
fieldName = "IDLEGITIMATIEBEWIJS";
dbField.Description = fieldName;
dbField.HeadingText = fieldName;
dbField.Name = fieldName;
dbField.Type = CrFieldValueTypeEnum.crFieldValueTypeInt64sField;
fields.Add(dbField);
// More code for more tables to add.
table.DataFields = fields;
//CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo info =
// new CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo();
//info.Attributes.Add("Databse DLL", "xxx.dll");
//table.ConnectionInfo = info;
// Here an error occurs.
databaseController.AddTable(table, null);
ReportDoc.SetDataSource( [MyFilledDataSet] );
//object path = @"d:\logfiles\";
//ClientDoc.SaveAs("test.rpt", ref path, 0);
The object ClientDoc referes to a ISCDReportClientDocument in a base class:
internal abstract class Worker
private ReportDocument _ReportDoc;
private ISCDReportClientDocument _ClientDoc;
private string _ReportFileName;
public Worker(string reportFileName)
_ReportFileName = reportFileName;
_ReportDoc = new ReportDocument();
// Load the report from file path passed by the designer.
_ReportDoc.Load(reportFileName);
// Create a RAS Document through In-Proc RAS through the RPTDoc.
_ClientDoc = _ReportDoc.ReportClientDocument;
public string ReportFileName
get
return _ReportFileName;
public ReportDocument ReportDoc
get
return _ReportDoc;
public ISCDReportClientDocument ClientDoc
get
return _ClientDoc;
But I get an "Unspecified error" on the line databaseController.AddTable(table, null);

How to create a job card and how to add waranty card in sales order
I have one scenario for CS.the scenario is realted to automotive industry. Basically its a trading industry of HCV,MCV,LCV apart from that they will do servicing also. First the customer comes for a service.he is having free services. he will have waranty for spare parts of the vehicle. once he comes for servicing first the executive will take complains from the customer after that a Job card will be issued to the customer. there his chasis no ,engine no and registration no will be there. once enter the chasis no entire customer details has to come. how many free services he is having for how many kilo meters.then job card will go to the spare parts dept.that dept will issue the spare parts.then they will invoice the customer. he will pay the payment.and finally the gate pass will be given to the customer to deliver the vehicle.
painful area is how to create a job card and how to add waranty in sales order.

2.1.How to create or display default date and time values?
1.
create input field for DATE and TIME on screen.ex. DATE1 and TIME1 are screen field names .
2.
Just assign SY-DATUM to DATE1 and SY-UZEIT to TIME1 under PROCESS BEFORE EVENT.
3.How to create text box for giving comments?
1.
Define one variable in the TOP include with type STRING means Global variable.
2.
Create one input field by giving screen field name which u have defined in the above step.
4.How to store the records that we are entering in a table?
For this case.. Create one table control. you can select one record and create record in the Z table by pressing button on Application toolbar..
Check the following steps to handle Table control.
1).
U should take one variable in your internal table or in structure which
is used for table control fields
ex :
data :
begin of itab occurs 0 ,
mark type c , "This is to select the record.
matnr like mara-matnr ,
matkl like mara-matkl,
maktx like makt-maktx,
end of itab .
Controls: TABC types TABLEVIEW using screen 100.
2).
This mark variable should be given in Table control properties.
follow the path
double click on the table control-->attributes .->select
w/SelColumn and in that itab-mark. Check in the figure.
[Table control properties screen|http://bp2.blogger.com/_O5f8iAlgdNQ/R99gOUH8CXI/AAAAAAAAA9I/d3gOum1fJ6s/s1600-h/pic28145-796618.jpg]
3).
After that. Take this example.
PROCESS BEFORE OUTPUT.
MODULE STATUS_0100.
LOOP AT ITAB WITH CONTROL tabc
ENDLOOP.
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.
LOOP AT ITAB.
