Generating picture on Applet after fetching it from Database
Hello,
I want to display the picture of employee in my JApplet. The data base which I am using is SQL Server 2000.I will be storing it under image data type in data base.
How will I retrive the picture of employee when Employee I.D is selected. Any code will be greatly helpful.
Regards
Sandeep Williams
An image data type in SQL Server is mapped to java.sql.Types.LONGVARBINARY which should be read by using the ResultSet getBinaryStream method. Aside from that, it would be hard to provide you with any code becasue:
1) it all depends on how and the type (e.g., JPEG, GIF, PNG, BMP, etc....) of image was stored in the database,
2) version of java that you're using or targetting 1.1, 1.2,1.3,1.4, etc....
Good luck!

if i view it in using AppletViewer it runs perfectly and display the data in JLabel. (ie, both jlblTitle and jlblNewTitle).(ie, DATA FETCHES FROM db AND DISPLAYS PROPERLY)
BUT IF I CLICK ON INDEX.JSP, ONLY jlblTitle APPEARS. jlblnNewTitle WILL BE BLANK(this label name is supposed to fetch from database)
EVERY THING IS DISPAYING PROPERLY EXCEPT DATA FROM DATABASE!!!

How to fetch data from database in javafx 2.2 table which is editable.
Dears!
I want to fetch data from database in javafx 2.2 tableformat with jdbc , which is also editable and i can add more records in this table also.
Can anybody help meI can vaguely recall some sort of JavaFX database connectivity feature, I'm not sure if it's valid anymore.The link is based on JavaFX Composer which only applied to NetBeans 6.9 and JavaFX 1.x (both of which are now dead techs).
There is a good chance you will have to write your own. There are several blogs describing other peoples' work. You could probably use them as a reference.Here is Narayan's basic [url http://blog.ngopal.com.np/2011/10/19/dyanmic-tableview-data-from-database/] tutorial for displaying data from a database in a TableView, you'll need to look elsewhere for the editing portion.
The [url http://docs.oracle.com/javafx/2/ui_controls/table-view.htm]JavaFX TableView tutorial gives info about how to handle edits in a TableView, but you will need to tie the updates back to the database yourself.
It is possible that [url http://www.javafxdata.org/]DataFX may provide some facilities to help support you. -
Fetch records from Database based on Input value
Hi Experts,
In my mobile application, I have designed one input field with F4 help or input assist. I need to fetch records from database based on that input and need to display records in table.
My question is:
How to fetch the records from database/back end based on the input value and display them as table format as we are doing in SAP ABAP?
Here, I need to fetch the records based on input value available in the UI screen and pass that value to gateway, fetch the records from database and need to bind with table in SAPUI5.
Kindly share the whole process flow with sample code for this requirement. Hope I have explained the requirement in detail.
Thanks In Advance..
Regards,
Arindam Samanta.Hi,
Try something like this.
In this, I am passing From date, To date, RelGrp, RelStr, Uname as input. Then I am storing those values in variables and passing this data in Odata request.
OData.read({ requestUri: "http://xxxx:8000/sap/opu/odata/sap/Z188_PO_SRV/pos?$filter=Docdate le datetime'"
+ todateformat+"T00:00:00' and Docdate ge datetime'"
+ fromdateformat+"T00:00:00' and RelGrp eq '"
+ relcode +"'and RelStr eq '"
+ relstg +"'and Uname eq '"
+ username+ "' "},
function (data) {
console.log(data);
When we are giving correct inputs it will goes to Success function and get the data from back end.
In console we can see the data.
Hope this will helps to you.
Thanks&Regards

Same query takes different time to fetch result from Database
Hi all,
I am having a scenario in which a query is taking different time keeping other environmental variables constant.
When that query runs for 1 user it takes just 2 minutes to fetch result and the DB connection becomes inactive after fetching the result.
But if I run the same query after some time in similar environment it takes 25 minutes. sometimes 40 minutes to execute and give the result to the app server from the same database.
I am not able to understand this behavior from DB. Can anybody try to explain this behavior?
The details of the DB are,
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production
PL/SQL Release 11.2.0.1.0 - Production
CORE 11.2.0.1.0 Production
TNS for 32-bit Windows: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production
OS Details:
Windows 2008 server Enterprise Edition.
I tried analyzing that query in oracle, it recommended there are lots of hard parsing in that query.

Getting virtual memory error when fetching records from database
HI,
I am using Oracle as Database and the Oracle JDBC driver. I have simple code which is a select statement but the problem is the resultset dies while fetching the data i.e. 5,50,000. And it gives me the memory error as its storing all in the memory. One of the way which i have serched in the old threads is using the batch method fetching rows at a time but can you tell me how to implement in my code. I am pasting my code.
The overall functionality of my code is that it's reterving data from database and generating an XML file that would be validated with a DTD.
//My Code
public class Invoicef3 implements ExtractF3 {
final String queryString = "select * from hsbc_f3_statement
order by bill_no, duplicate,
invoice_address1,
invoice_address2,
invoice_address3,
invoice_address4,
invoice_address5,
invoice_address6,
main_section, order_1, page,
section, product_category,
sub_sect_1, order_2,
sub_sect_2, child_product,
sub_sect_3, account,
line,entry_date, currency, tier";
public ArrayList process() {
Connection con = null;
Statement stmt = null;
ResultSet rset = null;
ArrayList arr1 = null;
try {
con =
ConnectionManager.getConnection();
stmt = con.createStatement();
rset = stmt.executeQuery(queryString);
arr1 = new ArrayList();
while (rset.next()) {
arr1.add(
new F3StatementExtract(
rset.getString(1),
rset.getInt(2),
rset.getString(3),

stmt.close();
} catch (SQLException e) {
e.printStackTrace();
} finally {
ConnectionManager.close(rset);
ConnectionManager.close(stmt);
ConnectionManager.close(con);
return arr1;
}The problem is that you are fetching and processing all the rows for the query, which the VM cannot handle given the heap space available. The points you could think over are:
* Allocate more heap memory (this would help only to a limited extent)
* Try to process only a few records at a time instead of all of them (there is actually no need to process all the records at a time. Try processing records in lots of say 1000)
* Avoid selecting all the columns [SELECT *] from the table, if all of them are not going to be used.
There is a slight change i have done in the code is that i am using two quereies now one is fetching all the Bills and the secondquery is fetching all the data for the relevant BILL.
//My Code
public class Invoicef3 implements ExtractF3 {
/*Query to get distinct bill numbers*/
final String queryString1 =
"select distinct(bill_no) from hsbc_print_bills";
/*Query to get distinct bill numbers statement details*/
final String queryString =
"select * from hsbc_f3_statement where bill_no='";

Dynamically fetch data from database and display it in the report
Hi,
We have a requirement in developing a report which needs us to dynamically fetch data from the database and display it in the report.
We have a column called WORKER in the report.
For each worker there is a measure(PSA) associated with it.
In the report we have to display both the WORKER and the PSA column.
What we want is, when we display the list of the workers, the corresponding workerid_id of the worker will be passed and the value of his PSA will be fetched from the database and displayed in the report.
Or anything similar to this.
We also have drill applied on this WORKER column. So after any drill up or drill down also the value for PSA should change.
Is there any way of doing this?
Please help if possible.

Long time taken to fetch data from Database Table
Moved to correct forum by moderator.
I had a requirement where i need to fetch records from table A912 for the matching entries in an internal table and satisfying some conditions.
The Internal Table(it_out) has 1,206 entries, while Databse table(A912) has 9,758,234 entries.
The Structure of Internal Table and Select Query are,
TYPES : BEGIN OF ty_a912,
matnr LIKE a912-matnr, "Material

datbi LIKE a912-datbi, "Validity end dt

knumh LIKE a912-knumh, "Cond rec no.
END OF ty_a912.
TYPES : BEGIN OF ty_out,
erdat LIKE vbak-erdat, "Date
vbeln LIKE vbak-vbeln, "Sales document
posnr LIKE vbap-posnr, "Item
kunnr LIKE vbpa-kunnr, "Customer

END OF ty_out.
SELECT
matnr kunwe datbi datab knumh

FOR ALL ENTRIES IN t_out
WHERE matnr EQ t_out-matnr
AND kunwe EQ t_out-kunnr
AND datbi GE t_out-fkdat
AND datab LE t_out-fkdat.
It takes very long time to process this select query, is there any alternate way?
Please suggest some valid solution for this issue.

Hi,
can you give us an SQL trace in ST05? The SQL Trace (ST05) Quick and Easy
The FAE will be processed in a special way: see https://forums.sdn.sap.com/click.jspa?searchID=-1&messageID=6630311
If an index is NOT supported the FAE part will take forever...
if t_out is filled by another table you may go for a join? But again, index support is the key

LabVIEW Memory full while fetching data from database
Hi,
In my program I need to sync some data from client PC as per the selected time frame.
But while fecthing the data from the clinet database, my application is hanging and when I run it with code I get the 'LabVIEW memory full' error message.
Kindly suggest to overcome this problem.Fetching the entire database is probably not a good idea. You should narrow down how much you read at a time.

How to fetch data from DataBase using Servlet ?
Hi all,
Till now, i was just sending values from web page and receive the data in excel format using servlets.
But, now, i want to fetch data from data base. I will be giving inputs in the web page(for the query)....ON click of submit button,
Servlet should be called.
Depending on the input, query has to be executed, and response should be sent to the user.
How to do it?
Code
import java.text.*;
import java.sql.*;
import java.util.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.OutputStream;
/** Simple servlet that reads three parameters from the html

String url = "jdbc:odbc:Testing";
con = DriverManager.getConnection(url, uid, pwd);
Statement s = con.createStatement();
query = "select * from gowri.msllst1";

Is this format is correct? am i placing this doGet method at the right place? is my program's logic is correct?
Please help me?

Fetching data from database in case of mixed case in SE37
Hi,
I have created a function module(in se37) where the input is Last name(PA0002-NACHN). My requirement is i have to fetch data from PA0002 based on last name. But the problem is if i give a name in mixed case(both upper and lower) sap converts the last name into Capital letter and starts searching the database.
But i tried in abap editor. here SAP accept the parameter(last name) as mixed case and starts searching. Why in function module the parameters are converted into upper case. How to restrict it.
If i will create a domain with LOWER CASE check box checked and try to call the dataelement in import part of function module then also it's converting it inot upper case. If i uncheck the lower case check box then also it's taking it as upper case.
How to process the input parameter in function module(SE37) which should take the input as user enters,i.e if user enters small letter it should take it as small letter , if mixed letter it should take it as mixed letter and start searching.
regards
sandeepHI sandeep,
<i>"If i will create a domain with LOWER CASE check box checked and try to call the dataelement in import part of function module then also it's converting it inot upper case. If i uncheck the lower case check box then also it's taking it as upper case."</i>
I think the data is getting converted to upper case even before it is passed to this FM.
Can yo ushow how are you testing this FM?
If you are calling this FM in a abap program using a parameter, it will convert the text to upper case as and when you enter data the name in it.

</html>i think normally u will get data from databsae as objects.they are like java beans having getter and setter methods.so you create a collection of those objects like collect all the objects coming from database into an arraylist or....
suppose you want to populate the dropdown box with say "username" from database object s, your code will look like that
<html:select property="name">
<html:options collection="databaseList" property="username" />
</html:select>
"databaseList" is collection(say.. ArrayList) of objects you are getting from database.this dropdown will contain all the "usernames" you are getting from database. -

Unable to fetch records from database with huge selection screen
Hi all,
I have 20 fields from selection screen.
I have a z table with these 20 fields .
Now with the values entered in the selection screen i have to fetch the records from the z table.
All fields in the selection screen are not mandatory, the user may or may not enter the values.
I have to fetch the records based on the values entered.
I wrote a select with where condtion to all those 20 fields. but its not retreving the records.
All the fields in the selection screeen are parameters.
Could you help me on this, please. I wrote in the where conditon with field1 = value AND field 2 = value.. etc... field20 = value.
Please guys help me out.
KV.
Edited by: Nithin Kumar on Mar 18, 2008 8:48 AMGuys,

But i have couple of fields as descriptions. So i have to fetch the records for pattenr as well.
Means, user can enter in the description............. like "ab". So in the description if there is anything with 'ab' it should fetch.
it works with a LIKE statement with % symbols.
but it doenst work with ranges and patterns in same select. I mean the below is not working.
SELECT *
FROM crmd_orderadm_h
INTO table itab
WHERE object_id IN r_obj AND
process_type IN r_pro AND
description LIKE s_des.
r_obj, r_pro are ranges and s_des is the pattern, ex: %ab%. so in this case how it has to be done... could you please help me on this.. the other fields could be blank( r_obj and r_pro)..
kindly help me out......
