hi,
Can any one please tell me how to transfer a set of data from Excel spread sheet to an Access database using SQL query.I'm using java API currently. I have done all sorts of ODBC connection in administrative tools.The file is in correct location. I have done certain coding but with errors.Help me to get rid of these errors,
Coding:*
try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection datacon=DriverManager.getConnection("jdbc:odbc:exdata","",""); *//For Excel driver*
Connection datacon1=DriverManager.getConnection("jdbc:odbc:stock1","",""); *// For mdb driver*
Statement datast=datacon.createStatement();
Statement datast1=datacon1.createStatement();
ResultSet excelrs=datast.executeQuery("select item_code,sdata,closing_stock from phy "); *//phy is the excel file*
while(excelrs.next())
String ic=excelrs.getString("item_code");
System.out.println(ic);
String d=excelrs.getString("sdate");
double cs=excelrs.getDouble("closing_stock");
int dbrs=datast1.executeUpdate("insert into second values('"+ic+"','"+d+"',"+cs+")"); *//second is the mdb*
excelrs.close();

The fact that Excel can import a csv file doesn't make it an excel file.
If you have a csv file then you must use a csv driver or just use other code (not jdbc) to access it. There is, normally, a ODBC (nothing to do with java) text driver that can do that.

How do I programatically set the date and time of my FP-2000 in LabVIEW RT?

I checked out the following knowledgebase document which has a tool for setting the system time, but I also need to set the date:

How can I do this?
-Jim

That is great, Steven. I also found a solution using GetSystemTime and SetSystemTime which are functions in kernel32.dll that get and set the system date-time. This function call worked on the FP-2000 that I have and should work on RT-Embeded systes, as well.

How to return a set of all objects

hi,
i have a simple POJO called Items, for example. In my POJO all I have is two fields, the id and the price of the item which comprise to be two fields in the corresponding table in the database. then i have the getters and setters for these two fields.
i want to have a getItems() method which would essentially return a set of all items. i'm not sure as to how to do this, should there be a loop in the getItems() method which would go through the rows in the table and keep on adding the rows to the set until there are no more rows?
what's the correct way to do this? any ideas, suggestions will be helpful. thanks!!

What do you mean "return a set of all items"? You mean all the entries of this type in the DB? Then run query "select * from whatever_that_table_is", iterate over the result set, and and one object to a List for each row. Of course, this is not generally a good approach, as it's quite possible for the number of rows in the DB to exceed what you can hold in memory at one time.
What part are you having trouble with?

How to decode a set of datas received from serial port and display image on a canvas based on CVI ?

Hi !
I have received a set of datas via rs232 and it contains picture messages. I have to decode the datas first and then display them on a canvas.
I have known several functions that may be used . Such as
int SetBitmapData (int bitmapID, int bytesPerRow, int pixelDepth, int colorTable[], unsigned char bits[], unsigned char mask[]);
int CanvasDrawBitmap (int panelHandle, int controlID, int bitmapID, Rect sourceRectangle, Rect destinationRectangle);
However,I don't know how to set the following parameters according to the actual pixel values and color values.
int bytesPerRow, int pixelDepth, int colorTable[], unsigned char bits[], unsigned char mask[]
What's more,I have no idea how to decode the datas.
The attachment is a incomplete project. I will be very appreciated if anyone could help me .
Best regards.

I wouldn't care success or failure,for I will only struggle ahead as long as I have been destined to the distance.

Decode and display image.zip ‏212 KB

Well, things are getting a bit clearer now.
1. Your image is actually 240x240 pixel (not 320x240 as you told before). The size of image data is 57600 bytes which corresponds to that frmat (I was puzzled by such a data size compared with larger image dimensions!)
2. The image is a 8-bits-per-pixel one; this means that you must provide a color palette to create the bitmap
3. You cannot simply copy image data into bitmap fields in CVI: CreateBitmap always produce an image with pixeldepth matched with display colour depth (normally 24 or 32 bpp)
All that means that you must:
1. Create the appropriate color palette with 256 colors: it may be a grayscale or color palette depending on camera characteristics. Grayscale palette can be found in my sample project, while sample colour palettes can be found here (here the description of a "standard" 8-bpp color palette)
2. Create the bits array correctly dimensioned for the color depth of your monitor
3. Get each pixel value from the camera, lookup in the color palette for the appropriate colour and create the RGB informations into the bits array in memory
4. Display the bitmap on the canvas
As a first step, I would configure my system for 256-color display setting, create a bitmap and simply copy image data into it: you should be able to get the correct image back to your screen.
Proud to use LW/CVI from 3.1 on.

How to reduce the number of data blocks used by table

Hi,
I was trying to reduce the space usage of a particular table of my apex application which stores blob content and therefore deleted many records from it.
However, the data block usage remained the same as before.
I have tried to 'analyze' the table and validate the structure,but am unable to overcome this problem.
Could someone throw some light on what needs to be to reduce the number of data blocks used by this table?
Best Regards,
Priya Jetley

Priya:
It is likely that the BLOB content defined in your table is being stored 'Out-of-Line'. This means that the LOB columns are stored in segments of their own. These then are the segments that may need shrinking.

How to count the days between Date Range using OO ABAP?

hi experts,
        i want to count the days between Date Range using OO ABAP for that which class and method can i use?.
Thanks,
Mahesh.

Not sure I understand the requirement for it to be OO, but you could always write your own (i.e. use this):
REPORT zz_date_diff.
CLASS date_diff DEFINITION.
PUBLIC SECTION.
    METHODS diff IMPORTING     i_date_fm TYPE d
                               i_date_to TYPE d
                 EXPORTING     e_days    TYPE i.
ENDCLASS."
CLASS date_diff IMPLEMENTATION.
METHOD diff.
    e_days = i_date_to - i_date_fm.
ENDMETHOD."
ENDCLASS."
DATA: g_ref TYPE REF TO date_diff,
      g_days TYPE i,
      g_date_fm TYPE d VALUE '20080101',
      g_date_to TYPE d VALUE '20090101'.
START-OF-SELECTION.
CREATE OBJECT g_ref.
CALL METHOD g_ref->diff
    EXPORTING
      i_date_fm = g_date_fm
      i_date_to = g_date_to
    IMPORTING
      e_days    = g_days.
WRITE g_days.

BI & Oracle XI data exchanges using WEBServices (into both sides)

Hello,
Would you be so kind and give me suggestions.
We have:
BI 7 server Oracle Exchange Infrastructure Oracle DB server
Our client wants to implement this data exchange solution:
Scenario A: i have load data to BI from Oracle DB
My steps are: from BI i have to call WEBService from Oracle Exchange Infrastructure when Oracle Exchange Infrastructure calls WEBService from Oracle DB and Oracle DB returns data set to BI via Oracle Exchange Infrastructure.
How to schedule job for calling WEBServices from Oracle Exchange Infrastructure? What have i configure in BI?
Scenario B: Application based on Oracle DB wants to get data from BI
Steps are: Oracle DB calls WEBService from Oracle Exchange Infrastructure when Oracle Exchange Infrastructure calls WEBService from BI and BI sends data to Oracle DB via Oracle Exchange Infrastructure.
BI offers Open Hub Service for data distribution from BI, but I didnt find description how to distribute data using WEBServices.
Is is possible to implement Scenario A and Scenario B in BI with standard tools.
Could you give me detailed answers(step-by-step what I have to do)?
Thanks in advance.
Best Regards,
Arunas Stonys

Arunas,
Quite an interesting landscape....
Also what do you mean by standard tools ?
Option A :
You can use the XML datasource for the same and once the XML data source is called , the data enters the Delta Queue in the BI server and from there you can use the normal infopackage / real time daemon to load data into your cubes / DSO. The XML datasource works on SOAP and this has to be supported by the Oracle XI.
Option B:
Slightly more trickier since you are hitting the BI server directly....
I am not sure if an infospoke can be a web service but some of the ways this could be done is :
a. Have an Func Module which acts as a web service and have that FM return the data
b. Have SAP XI inbetween to do the same
Also on the landscape- depending on the nature of data loads / data requests - if BI-Oracle is more - you can look at having SAP XI there instead....
Arun
Hope it helps....
P.S I would also suggest that you post the same in the Enterprise SOA forums / enterprise web services and people like Karthik Iyengar , Durairaj etc can respond to the same in a much better way that what I am able to give you right now...

How can I retrieve a LONG data type using ADO

In VB I am using an ADODB object to retrieve data from an Oracle table that has a LONG data type column...
specifically: SELECT TRIGGER_BODY FROM USER_TRIGGERS WHERE TRIGGER_NAME = 'MYTRIGGER'
I have tried using the GETCHUNK method but it only returns the first 150 or so characters no matter how
many times I call it???? here is the sample code I'm using........
Dim Cn As ADODB.Connection, Rs As ADODB.Recordset, SQL As String
Dim sChunk() As Byte
Set Cn = New ADODB.Connection
Set Rs = New ADODB.Recordset
Cn.CursorLocation = adUseServer
Cn.Open "Provider=OraOLEDB.Oracle.1;Password=hrzadmin;Persist Security
Info=True;UserID=hadmin;Data Source=xxx.local"
SQL = "SELECT trigger_body from user_triggers where trigger_name = 'MYTRIGGER'"
Rs.Open SQL, Cn, adOpenStatic, adLockReadOnly
Debug.Print Rs!trigger_name
Debug.Print Rs!trigger_body
sChunk = rs.Fields("trigger_body").GetChunk(500)
Debug.Print sChunk

I have a similar code which works for chunk size >400,
The image I am trying to retrieve is huge so the chunksize is also more.
Did you try with any non meta table?
For your reference I am pasting my application code below.
Hope it helps.

How to find the value of date char used as exception aggregation reference

Hi BI Gurus,
On a BEx report I need to list three things by material:
1)   the open (not yet delivered) Purchase Order quantities
2)   the PO quantity to be delivered next and
3)   the date that belongs to the next delivery
The model supports these data i.e. for each material I can list all open quantities by Purchase Order / Item / Schedule line and the scheduled delivery dates are also available as a characteristic.
Determining 1) is easy as the drilldown is fixed (materials only) the open quantities get summarized for all PO-s belonging to the materials.
To determine 2) I used a Calculated KF simply including KF 1) =Open PO Qty in the definition and setting Exception Aggregation (first value) with a reference char of the delivery date. This gives back the Open PO Quantity to be delivered first.
My question is about how to determine the 3rd value (actually this is not a KPI but a characteristic value). In other words, for each materials I would need to determine the first among all of the possible delivery date char values of the open PO Items / schedule lines. This is the date the quantity shown in the 2nd KPI will be delivered on.
Does anybody have an idea how to approach this issue?
Thanks for you help in advance,
Attila

Hi Olivier,
Thanks for your suggestion. I got a bit closer with the replacement path formula variable and the CKF. I tried to apply the same logic of KPI 2) but for some reason it did not work. Actually, it delivers the right value but only when 0SCL_DELDAT (Scheduled delivery date) is in the drilldown But what I need is the first delivery date by Material only, and without this 0SCL_DELDAT drilldown.
Any other ideas?
Thanks and bye,
Attila

How to find Maximum of a date field using BEx

We are trying to just display the maximum of a date field in a BEx report along with some fixed text .
If we need to create a formula using Maximum function , how to use the same?
For ex, we have a field "Flight Date" in the cube and cube has been updated with flight date till 10.09.2006.
we want to display in the BEx report something like "Flight details are available only till <maximum of the flight date field from the cube>"
Please help.

Srilakshmi,
Create a formula on the data and then sort the query on the date , that way the latest date would come on top. I am not sure if you can have something the way you have described..
an option could be :
Have a query on the cube with a condition of top date where the date could be a formula , this way you would get the latest date. se this as a value set to filter another query that displays only the date and nothing else , have some static text beside the query to indicate that this is the latest date.
Hope it helps..

How to populate a ComboBox with data from a WebService

I have a simple application that has a DataGrid that gets its
data from a web service. I would prefer to put that data into a
ComboBox instead of a DataGrid. My web service returns objects.
Anyone have any idea how to do that?
<mx:DataGrid id="dgProjects"
dataProvider="{ws.getProjects.lastResult}" >
.....<mx:columns>
..........<mx:DataGridColumn dataField="projectID"
headerText="Project ID" width="100"/>
..........<mx:DataGridColumn headerText="Project Name"
dataField="projectName"/>
..........<mx:DataGridColumn headerText="Doc UNID"
dataField="docUNID" visible="false"/>
.....</mx:columns>
</mx:DataGrid>

I tried that but it doesn't work. However, I just found part
of the solution and that was to add labelField="projectName".
That worked. Now, I want to glue together projectID with
projectName and a dash between them. So I changed it to labelField
= "projectID - ProjectName" and that causes the combo box to
display [Object] [object].
Any ideas how to glue those items together?
