Database conection

i am the begginer for netbeans API , so i want to learn how to connect java GUI application with oracle database.
if any one have tutorial, E-books , Referance links to learn this thing plese send to me.

Netbeans isn't an API. It is just an IDE. A tool.
With regard to the Java DataBase Connectivity, just learn the JDBC API.
Here's a tutorual: [http://java.sun.com/docs/books/tutorial/jdbc/index.html].

Change Database Conection?

I have a Datasource reference to my local SQLServer in my project.
I need change it to other database server on deploy.
Is it possible? Where i change conection parameters.
thank in advance

Hi, you can change that through application server admin console. What application server do you use? In case of Sun App Server 8.x this is under Resources/JDBC/Connection Pools/ branch in admin console.

Secondary database conections

im working in a proyect, that consist in send data to other db server that is not on the r3 database server,
both database server are running on SQL Server 2000.
The version of sap is 46b.
S.O. Windows 2000 SERVER
THe secondary database is in Windows 2000 Server too.
i found information in the notes: 313151,178949.
i fill the table dbcon as follow:
Connection name : SAPPVF
DBMS:MSS
User name: csappvf
DB password *** / ********+
Conn. info: MSSQL_SERVER=NHUERTA MSSQL_DBNAME=PRU
csappvf, is the user with permision dbo in database PRU.
Where NHUERTA, is secondary server, where is the database PRU.
PRU, is the secondary database
Code program abap.
EXEC sql.
CONNECT TO 'SAPPVF' AS 'MIM'
ENDEXEC.
EXEC SQL.
     SET CONNECTION 'MIM'
ENDEXEC.
IF SY-SUBRC = 0.
    EXEC SQL.
      SET CONNECTION 'MIM'
    ENDEXEC.
    EXEC SQL.
      SELECT single * INTO :WA_RENTA FROM RENTA
    ENDEXEC.
   but the program generate a dump:
ABAP/4 Program ZMX_BC_IN_CONEXION
vSource ZMX_BC_IN_CONEXION
Line 38.

Table does not exist in database....
   How i can identify if the problem is of basis
                                                             Someone have any suggestion about this !!!

Hi Noemi,
1. As u said, you have a secondary database connection
   which is tested and working. (But giving
   error in ur Z program)
2. SAP recommends that instead of using NATIVE Sql,
   use OPEN Sql.
   So that if there is any change in database,
   the R/3 system(Database Manager) will automatically
   take care of it)
3. According to me, you should you OPEN Sql.
   To do this,
   you will have to create the same Z / Y table
   in your R/3 database, with the same structure.
   This can be a blank table or structure.
   SO THAT ABAP IDENTIFIES IT AS A DATABASE OBJECT
   IN DD DICTIONARY WHEN SYNTAX CHECKING THE SQL.
4. One can use the following syntax.
      DATA: mydbcon(30) TYPE c.
      mydbcon = 'SAPPVF'.
     Select * FROM YTABLE CONNECTION (mydbcon)
     into ITAB.
HOPE THIS HELPS

Amit M.

Seeing tables from database conection for a user

I created a bunch of tables under a db admin
I created a user aaa
I granted all priveliges on all tables created to user aaa including "CREATE CONNECTION"
I created a JDev Database connection through user aaa
Test connection works fine. I open up the connection and try to look at the created tables. No tables! The display is empty
I can see the tables from admin user connection fine. Why can't the connection through user aaa see the tables?
Oracle 11g; JDev 11g P4
Thanks
Doug

Hi,
doesn't reproduce for me. Please make sure the user has granted select on the other user's tables

Re:The database conectivity

Hi,
We are running out of database connections even though we have configured 150 as max connectivity in the connection pool and we have 65 sessions in the database where the limit is 500 sessions. Even though we restarted the weblogic server, the sessions were hanging out in the database
But we should not get the max capacity of connection pool as we have another 85 connections available. When we killed the session in the database and restarted the weblogic servers that cleared the problem. I am getting the following errors before we killed the sessions

UPDATE records using Database Conectivity toolset

I´m using LabVIEW 8.5 & Database Connectivity toolset ver 1
When I try to update a record of a MS ACCESS 2003 with the SQL UPDATE TablenName SET field1=newvalue, field2=newvalue........WHERE condition=x, I get the error -2147217900 Exception occurred in Microsoft Jet DataBase engine: Sintax error in the instruction UPDATE.vi ComExec (8.5 bug Workaround)vi.
I ´dont think I have made a sintax error. If the field is an string I use the 'newvalue' following by a comma, in case of numeric field just the coma. For instance :
UPDATE TableName SET Name='John', Age=22,Hair='blond' WHERE height=1.85
I have discarded the reserved word´s problem, as I can insert records in the data base without any problem
Any idea to solve the problem
Thanks
Simbani

Did you try it like this?
UPDATE TableName SET TableName.Name='John', TableName.Age=22,TableName.Hair='blond' WHERE TableName.height=1.85

ACCESS DATABASE CONECTION WITH CRYSTAL REPORT XI

Hello
During many years we have been working with the CRYSTL32.OCX of the CR version 8.
Recently we have had to upgrade to CR XI Release 2 and many things are totally different.
Can somebody send me some example of using Visual Basic 6 to connect MSAccess Database 97 with CR XI versión ?
I supposse has not to be complicate because it is a very simple database but till now I have not got
it !!!
Thanks in advance

Well, the OCX was retired in CR 8.5. Your option now is to port your app to the report Designer Component (RDC). Another option is to go with the CR assemblies for .NET. I'd recommend the latter as the RDC has been retired in the currently shipping version of Crystal Reports, CR 2008 (12). Let me know which technology you choose and I'll supply links that will get you started.

Database conectivity toolkit.

Hola recien comneze un proyecto en el cual quiero mandar mucha información a una base de datos, esta información(strings, numericos etc) no solo se almacenara sino que se envia a dica base de datos paro poder ser modificada, elminada, actualizada etc, ahora lo que sucede es que es la primera vez que trabajo con bases de datos quiero saber que me recomiendan acces o SQL, o cuales son las desventajas la aplicación es un tanto sencilla pero está diseñada para envar muchisima información a la base.
A y si es posible conectar esta base de datos a un servidor??
Conozco el modulo Data Base Conectivity Toolkit de LV y es lo que planeo usar que me recomienda?
Solved!
Go to Solution.

Hola abraham94
Queria preguntarte si estas utilizando una misma base de datos para ambos? Tambien queria comentarte que el error que te aparece no mel o estas mostrando todo, del lado derecho se corta el error y se come una o dos palabras. Tengo una recomendacion para tu blockdiagram, cada ves que realiza una iteracion el ciclo while abres conexion y cierras conexion a la base de datos, no te recomiendo que hagas esto ya que estaras consumiendo recursos de tu computadora. Te recomiendo colocar la apertura de la conexion y el cierre de la conexion fuera del ciclo while a la izquierda y derecha respectivamente. Igual si puedes mandarme tu VI para revisarlo, tambien haciendo otra observacion no se si la diagonal que tienes en el nombre de las columnas sea aceptado debido a ser un caracter especial. Verifica eso, igual el guion medio que tienes en el nombre de otra columna. En el Front Panel si pueden aparecer esto signos sin embargo, en el arreglo de columnas creo que no son aceptados por la base de datos los caracteres especiales que te menciono.

CrystalConverter and new Database conections

I just converted a PLD to Crystal Reports layout with the CrystalConverter. I see a lot of formula fields. Now I want to add a reference to a table in the SBO database (for example OACT) in the Crystal Reports Layout. I have tried adding the table (OLE DB) but when i add the fields to a details section, the layout comes empty. Any help ?

When you add a table to the report. you have to check the links. Some auto links are not correct. You need manually correct them.
Thanks,
Gordon

You need to post your connection string, the database server you are using etc in order for anyone to help you.

Database conecting error.

Hello SDNers
I am unable to connect to oracle database. The Oracle TNSlistener service is not getting start. I am trying to start it manually then windows error-1067 "Process terminated Unexpectedly"
So how should I solve this problem?
Please reply and Thanks in Adnvance,
Jayendra

The Listener has NOTHING to do with support packages... it´s an operating system process, that can´t be started.
Check the logfiles "listener.log" and also have a look in your windows event log.

Lab view database conect to an exist db in SQL server

Hi
How can I connect my LV 8.5 with database connectivity to an existing DB in SQL server 2005 platform ?
thanks

1. Create a .udl pointing to your database.
2. Open Database Connection with the .udl as path.
3. Do your query/List tables
4. Close database connection

Actually this problem is a perfect case for why the DCT is a very poor choice. The problem is that the error message is not clear at all. The problem is that you are turning your input array of strings into a variant, but the results is a variant containing an array of strings. What the input wants -- but doesn't tell you -- is that it needs an array of variants where each element is a variant with a string in it.
Much better to use a simple interface that allows you to input SQL directly. Then when you get an error you can be sure that the error is actually telling you what is wrong. Check here for a broader discussion of the topic, and some drivers that won't cause problems.

Taking too much time (1min) to connect to database

Hi,
I have oracle 10.2 and 10g application server.

Please share your experience.

Dear AnaTech,
i am going to ask not related this question which already you answered i am going to ask you about that how to connect forms6i and Developer 10g with OracleAS.
i have installed and working Developer Suite 10g Ver. 10.1.2 and also Form Builder 6i. On my other machine i installed and working Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 and also on the database machine i installed Oracle Enterprise Manager 10g Application Server Control 10.1.2.0.2.
my database conectivity with Developer suite Forms and Reports and also Form6i and Reports6i are working fine. no problem.
now the 1 question of mine is that when i try to run form6i through run from web i got this error. FRM-99999: error 18121 occured see the release not.
this and the main question of mine is this that how can i control my OracleAS 10g with forms because basically the functionality of OracleAS is Mid-Tier but i am not utilizing the Mid-tier i am using here Two-tier Envrionment even i installed 3-Tier Environment so tell me how i utilize it with 3-Tier..
I hope you don't mind that i ask this question here and also if you give me you email then we can discuss this in detail and i can be helpful of your great expertise. i also know and utilize my 3-tier real envrionment.
Waiting for your great response.

How database connection pooling works in a application

Hi Guys,
I am new to Java and looking into best way of doing J2ee database conectivity. I am using Eclipse galileo3.5 J2EE with Mysql database and Tomcate 6.0.
I am developing an email application where I need to implement MVC model for my webapplication, using jsp for presentation, servlet for control and java beans for model.
I came across two tutorial for database connection pooling as given below.
Eclipse Corner Article: Creating Database Web Applications with Eclipse - In this tutorial connection pooling is configure in Tomcate 6.0
It says Copy and paste the following into your context.xml file (you may have to click on the Source tab at the bottom of the editor to be able to paste). This defines a DataSource with the name "jdbc/SampleDB". Our application will retrieve database connections from the pool using this name.
<?xml version="1.0" encoding="UTF-8"?>
<Context>
<Resource name="jdbc/SampleDB" auth="Container"
type="javax.sql.DataSource"
username="app" password="app"
driverClassName="org.apache.derby.jdbc.ClientDrive r"
url="jdbc:derby://localhost:1527/sample"
maxActive="8" />
</Context>
Where as in second tutorial - http://www.roseindia.net/answers/viewanswers/2838.html
It uses java bean for connection pooling and then use straight way in JSP and no Servlet used.
conpool.jsp
<%@page import="java.sql.Connection"%>
<jsp:useBean id="pl" class="com.CoreJava.ConnectionPooling"/>
<% Connection con = pl.getConnection(); %>
//do something using con
connectionPooling.java
import com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolD ataSource;
public class ConnectionPooling
static Connection con=null;
public static Connection getConnection()
try
MysqlConnectionPoolDataSource po=new MysqlConnectionPoolDataSource();
po.setServerName("localhost");
po.setPortNumber(3306);
po.setDatabaseName("mydatabase"); //changeur database name
po.setUser("root");//ur username
po.setPassword("");//ur password
con = po.getConnection();
catch(Exception e)
System.out.println("Exception Connection :"+e);
return con;
Please some one explain which is the best way of doing connection pooling to the database by using MVC pattern
Please if some one advise me how to use MVC architecture for simple email application and database connectivty.
Thanks

Never EVER use roseindia. It is terrible shit.
[http://balusc.blogspot.com/2008/06/what-is-it-with-roseindia.html]
The correct answer is what you found in the eclipse article. And you can read the Tomcat docs for more.
As per usual the code you have posted from Roseindia is a big pile of rubbish that was written by a complete idiot. I mean the person who wrote it apparently doesn't know much Java at all. Let alone JDBC. Or Connection pools. Or J2EE. It's not the worst I've seen from them but it's pretty bad.
