Generating sequence numbers not stored in the database
how to generate row numbers in the select statement
I need my query to return row numbers as a column which need to be displayed in the front end reporting tool.
should return something like this..
RANK NO DEPTID DEPT_NAME
1 10 SCOTT
2 10 JAMES
3 20 PETER
Something like
SELECT row_number() over (order by deptid) rank_no, deptid, dept_name
FROM deptJustin

When I select from the LOV, it is not storing in the database
Have a field (Manager) where the user selects their manager from the select list(generated from the query below)
select FIRST_NAME || LAST_NAME d, MANAGER_ID r
from PERSONNEL
where TITLE = 'MGR'
order by 1
After the manager is selected and Apply changes is clicked, nothing is stored to the database.
Have the Manager field specifications set as:
Source Used: Only when current value is session state is null
Source Type: Database column
Maintain Session State: Per Session
Source Value or Expression: MANAGER_IDWell, how have you created this form... manually or using wizard. If you have used wizard, then it would have asked you to select the table and it would have created process to update the same.
If you have created this form manually then you need to add a processs to update this to database...

I want to block unknown numbers which is not stored in the contacts
I want to block unknown numbers which is not stored in the contacts
Contact your carrier to see if they offer call blocking services.
If you just don't want to be bothered, you can set a custom ringtone for all of your contacts, then create or download a "silent" ringtone and set a custom vibration pattern of "none" and assign them as the default ringtone and vibration pattern. This won't actually block the calls, but you won't hear it ring and they will roll to voicemail. -
EJB 3.0 - JSF APPLICATION: DATA DOES NOT PERSIST TO THE DATABASE
Hi,
I am developing a JSF - EJB application and the data that I send from JSP Page through JSF Managed Bean --> Session Bean --> Java Persistence does not persist in database.
Here is my scenario ( Iam using JDeveloper IDE to create this application) -
SCENARIO START
The scenario consists of two web pages, one enlisting all the users stored in the database, the other contains a form for adding a user
1.) INDEX.JSP
2.) ADDUSER.JSP
Step 1: Create the USERS Table in database
CREATE TABLE users
user_id serial,
username varchar(255) NOT NULL,
first_name varchar(255),
last_name varchar(255),
password char(64) NOT NULL,
CONSTRAINT pk_users PRIMARY KEY (user_id)
Step 2: Add Database Connection To JDeveloper
Go to Database Connection Navigator and create a New Database Connection using the Wizard
Step 3: Create a New Application in JDeveloper and select JSF, EJB from Application Template
Step 4: ENTITY BEAN - In the EJB Node Right Click and Select EJB à New Entites from Table (JPA/EJB3.0)
Use The Wizard and create Entity Bean from Users Table which creates an Entity Bea POJO file as follows –
User.java -
package lux.domain;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.NamedQuery;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;
@Entity
@NamedQuery(name = "User.findAll", query = "select o from User o")
@Table(name = "USERS")
public class User implements Serializable {
@Column(name="FIRST_NAME")
private String firstName;
@Column(name="LAST_NAME")
private String lastName;
@Column(nullable = false)
private String password;
@Column(nullable = false)
private String username;
@Id
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="users_seq_generator")
@SequenceGenerator(name="users_seq_generator", sequenceName="users_user_id_seq")
@Column(name="USER_ID", nullable = false)
private Long userId;
public User() {
public String getFirstName() {
return firstName;
public void setFirstName(String firstName) {
this.firstName = firstName;
public String getLastName() {
return lastName;
public void setLastName(String lastName) {
this.lastName = lastName;
public String getPassword() {
return password;
public void setPassword(String password) {
this.password = password;
public String getUsername() {
return username;
public void setUsername(String username) {
this.username = username;
public Long getUserId() {
return userId;
public void setUserId(Long userId) {
this.userId = userId;
Step 5: STATELESS SESSION BEAN - In the EJB Node Right Click and Select EJB à New Entites from Table (JPA/EJB3.0)
Again Right Click on Model and create Session Bean from Wizard which creates two files –
UserDAOBean.java – Stateless Session Bean
UserDAO.java – Local Interface
package lux.facade;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.Query;
import lux.domain.User;
@Stateless(name="UserDAO")
public class UserDAOBean implements UserDAO {
@PersistenceContext(unitName="Model")
private EntityManager em;
public UserDAOBean() {
public User getUser(int UserId) {
User u = new User();
u = em.find(User.class, UserId);
return u;
public List<User> getAllUsers() {
Query q = em.createQuery("SELECT u FROM User u");
List<User> users = q.getResultList();
return users;
public void createUser(User u) {
String hashedPw = hashPassword(u.getPassword());
u.setPassword(hashedPw);
em.persist(u);
public void updateUser(User u) {
String hashedPw = hashPassword(u.getPassword());
u.setPassword(hashedPw);
em.merge(u);
public void deleteUser(User u) {
em.remove(u);
private String hashPassword(String password) {
StringBuilder sb = new StringBuilder();
try {
MessageDigest messageDigest = MessageDigest.getInstance("SHA");
byte[] bs;
bs = messageDigest.digest(password.getBytes());
for (int i = 0; i < bs.length; i++) {
String hexVal = Integer.toHexString(0xFF & bs);
if (hexVal.length() == 1) {
sb.append("0");
sb.append(hexVal);
} catch (NoSuchAlgorithmException ex) {
Logger.getLogger(UserDAOBean.class.getName()).log(Level.SEVERE, null, ex);
return sb.toString();
Step 6: Create a Deployment file in the Model and Deploy this to a JAR file
Step 7: Now Right Click on View/Controller Node and create a Java File –
UserController.java -
package lux.controllers;
import javax.ejb.EJB;
import javax.faces.model.DataModel;
import javax.faces.model.ListDataModel;
import lux.domain.User;
import lux.facade.UserDAO;
public class UserController {
@EJB UserDAO userDao;
private User user;
private DataModel model;
public String createUser() {
this.user = new User();
return "create_new_user";
public String saveUser() {
String r = "success";
try {
userDao.createUser(user);
} catch (Exception e) {
e.printStackTrace();
r = "failed";
return r;
public DataModel getUsers() {
model = new ListDataModel(userDao.getAllUsers());
return model;
public User getUser() {
return user;
public void setUser(User user) {
this.user = user;
Step 8: Configure page flow in faces-config.xml
1. Create the JSP file adduser.jsp by right-clicking View-Controller
node and selecting New > JSP. Use the wizard to create JSF – JSP Page, fill in
File Name adduser.jsp, click Finish. -
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

</head>
<body>
<f:view>
<h:form>
<h:messages/>
<h:panelGrid columns="2">

value="#{user.user.lastName}" />
<h:outputText value="Password" />
<h:inputSecret
id="Password"
value="#{user.user.password}"
required="true" />
<h:panelGroup/>
<h:commandButton
action="#{user.saveUser}"
value="Save"/>
</h:panelGrid>
</h:form>
</f:view>
</body>
</html>
2. Repeat the previous step for another JSP file failed.jsp.
3. On failed.jsp add the string
Save failed
Next we configure the page flow.
1. Open faces-config.xml.
2. Create index.jsp -
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

<title>User Listing</title>
</head>
<body>
<f:view>
<h:form>
<h:outputText value="User Listing"/>
<h:commandLink action="#{user.createUser}" value="Create a user"/>
<h:dataTable value="#{user.user}"
var="dataTableItem" border="1" cellpadding="2" cellspacing="2">

<h:outputText value="#{dataTableItem.firstName}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Last name"/>
</f:facet>
<h:outputText value="#{dataTableItem.lastName}" />
</h:column>
</h:dataTable>
</h:form>
</f:view>
</body>
</html>
3. Drag an arrow from index.jsp to adduser.jsp and replace the arrow’s label to create_new_user.
4. Repeat the previous step for failed, by dragging and arrow from adduser.jsp to failed.jsp renaming the label to f
ailed
5. Finally repeat the step for adduser.jsp, by dragging from adduser.jsp to index.jsp renaming the label to success.
This creates the following faces-config.xml file –
<?xml version='1.0' encoding='UTF-8'?>
<faces-config>
<managed-bean>
<managed-bean-name>user</managed-bean-name>
<managed-bean-class>lux.controllers.UserController</managed-bean-class>

Step 9: Create a Deployment file in the View-Controller and Deploy this to a WAR file
Step 10: Create a Deployment file in the View-Controller and create an EAR file and add Model’s JAR and View-Controller’s
WAR files to it.
Step 11: Run the JSP Files
SCENARIO END
Now, When I execute Index.jsp, it does not list values from database and when I click on Create User link, it takes me to adduser.jsp page. When I fill values in this page and click Save button, it takes me to Save Failed page and data does not persist to the database.
WHAT IS WRONG OUT HERE ???If you set a breakpoint in your createUser method - does this code get executed?
We have a couple of tutorials that might show you how to do this.

Step 6: Create a Deployment file in the Model and Deploy this to a JAR file
Step 7: Now Right Click on View/Controller Node and create a Java File �
UserController.java -
package lux.controllers;
import javax.ejb.EJB;
import javax.faces.model.DataModel;
import javax.faces.model.ListDataModel;
import lux.domain.User;
import lux.facade.UserDAO;
public class UserController {
@EJB UserDAO userDao;
private User user;
private DataModel model;
public String createUser() {
this.user = new User();
return "create_new_user";
public String saveUser() {
String r = "success";
try {
userDao.createUser(user);
} catch (Exception e) {
e.printStackTrace();
r = "failed";
return r;
public DataModel getUsers() {
model = new ListDataModel(userDao.getAllUsers());
return model;
public User getUser() {
return user;
public void setUser(User user) {
this.user = user;
Step 8: Configure page flow in faces-config.xml
1. Create the JSP file adduser.jsp by right-clicking View-Controller
node and selecting New > JSP. Use the wizard to create JSF � JSP Page, fill in
File Name adduser.jsp, click Finish. -
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>New user</title>
</head>
<body>
<f:view>
<h:form>
<h:messages/>
<h:panelGrid columns="2">
<h:outputText value="Username"/>
<h:inputText
id="Username"
value="#{user.user.username}"
required="true"/>
<h:outputText value="First name"/>
<h:inputText
id="FirstName"
value="#{user.user.firstName}" />
<h:outputText value="Last name"/>
<h:inputText
id="LastName"
value="#{user.user.lastName}" />
<h:outputText value="Password" />
<h:inputSecret
id="Password"
value="#{user.user.password}"
required="true" />
<h:panelGroup/>
<h:commandButton
action="#{user.saveUser}"
value="Save"/>
</h:panelGrid>
</h:form>
</f:view>
</body>
</html>
2. Repeat the previous step for another JSP file failed.jsp.
3. On failed.jsp add the string
Save failed
Next we configure the page flow.
1. Open faces-config.xml.
2. Create index.jsp -
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>User Listing</title>
</head>
<body>
<f:view>
<h:form>
<h:outputText value="User Listing"/>
<h:commandLink action="#{user.createUser}" value="Create a user"/>
<h:dataTable value="#{user.user}"
var="dataTableItem" border="1" cellpadding="2" cellspacing="2">

<h:outputText value="#{dataTableItem.firstName}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Last name"/>
</f:facet>
<h:outputText value="#{dataTableItem.lastName}" />
</h:column>
</h:dataTable>
</h:form>
</f:view>
</body>
</html>
3. Drag an arrow from index.jsp to adduser.jsp and replace the arrow�s label to create_new_user.
4. Repeat the previous step for failed, by dragging and arrow from adduser.jsp to failed.jsp renaming the label to f
ailed
5. Finally repeat the step for adduser.jsp, by dragging from adduser.jsp to index.jsp renaming the label to success.
This creates the following faces-config.xml file �
<?xml version='1.0' encoding='UTF-8'?>
<faces-config>
<managed-bean>
<managed-bean-name>user</managed-bean-name>
<managed-bean-class>lux.controllers.UserController</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>

Step 9: Create a Deployment file in the View-Controller and Deploy this to a WAR file
Step 10: Create a Deployment file in the View-Controller and create an EAR file and add Model�s JAR and View-Controller�s
WAR files to it.
Step 11: Run the JSP Files
SCENARIO END
Now, When I execute Index.jsp, it does not list values from database and when I click on Create User link, it takes me to adduser.jsp page. When I fill values in this page and click Save button, it takes me to Save Failed page and data does not persist to the database.
WHAT IS WRONG OUT HERE ???If you set a breakpoint in your createUser method - does this code get executed?
We have a couple of tutorials that might show you how to do this.

Where is the value of report repository stored in the database?
Hi all,
One of our developers is trying to write a code that would send the output report (pdf)of a process through mail, typical work flow stuff.But the problem is that we are not supposed to hard code the value of report repositiry from where the report has to be picked.can anybody suggest a table in the database from where the value of report repository can be queried.
we tried using
select reportrepositorypt from pswebprofile.
but this doesnt return the correct path. we went to PIA->peopletools->webprofile ->webprofie configuration
here we updated the value in report repository field and saved it and queried again.
But this didnt solve our problem.
Its showing the previous value which is different from the actual report repository path.
all the servers are in solaris box.
please suggets.
Thanks!Right now, I am trying to send a PDF (XML Publisher report) as an email to our vendors (it is their ACH Advice).
What I have done so far is: Created an App Engine, one step to populate a state record with run control information and the second step that runs XML Publisher and creates PDF report(s) which are published to the Report Repository and saved to a file on our network. Now I think I just need to create a third step to recall the PDF(s) and send the PDF(s) out as emails to our vendors.
I have found that the PDF information from Report Repository is stored in the Database in the CDM_LIST_VW record (this is a view and the main underlying table is CDM_LIST, but this contains what I need for now, so I'm going to try using it first). The Report ID is stored in the CONTENTID field and the Report Description (description shown on the Report Repository -- which in our case contains the email address) is stored in the CONTENT_DESCR field. So I am going to try over the next week to write the logic to query the CDM_LIST_VW for the data needed for the email address and the ReportID to go and grab the file....The hardest part is finding the actual file but I am hoping that I can also find a URL on that table. I'd pull the file from the network, but XML Publisher writes them out into numbered folders where all the PDFs are named the XML Report Defn - thus same name). I have not tried any of this yet, but am hoping I'm on the right path.
I hope this helped answer your question.
Good Luck!

Image compressed and stored in the database.
Hi,
We have a tiff file stored in the database and then compressed using the following Intermedia Oracle method.
process ('compressionFormat=FAX4,maxScale=1696 2200'); and save it back in the database.
This oracle database is 8.1.7.4. The tiff file gets processed when we use TIFF file generated by old scanner but errors out with the TIFF file generated by latest scanners.
The error I get is ORA 29400 , IMG-00704.
There is a difference in TIFF version in the outputs generated by two scanners,
The compression option : TIFF modified G3 in the old one
while the new one has Lempel-Ziv
Also, the tiff is loaded and saved fine but the image gets corrupted after the intermedia process method is run.Thank you for your reply. I am glad to find that I did not miss an option. I was aware that I could move my pictures into some other folder, but you have forgotten the solution that I chose. That was to go back and use ZoomBrowser, which works to access photos in any folder I choose. In addition it loads promptly. I have only spent a brief time using the ImageBrowser but don't recall seeing any enhancements that over ZoomBrwoser. Perhaps if I was attempting to interface with other software but as a stand-alone product, well perhaps you could enlighten me as to what makes ImageBrowser EX a better product.. Regarding the Accept as Solution: are you implying that Canon restricts their search function to only those responses that the OP marks as accepted?

Hi,
I am looking for an algorithm to generate alphanumeric sequence numbers in ABAP.
The sequence numbers should be in the following format
AAAA
AAAB
AAAC
AAAZ
AABA
AABB
AABC
AABZ
ZZZZ
Is there any built-in function module provided by SAP to accomplish this? Or something like a FOR statement as in C/C++?
Please help.
Helpful answers will be immediately rewarded.
Thank you.Hi,
I'm not sure, but maybe you can create a number range with SNRO for alphanumerical values
otherwise you have to create your own logic (you can use hexadecimal to ascii conversion in ABAP to increment the alphanumerical values)
Kind regards, Rob Dielemans -
After REFRESH the cached object is not consistent with the database table
After REFRESH, the cached object is not consistent with the database table. Why?
I created a JDBC connection with the Oracle database (HR schema) using JDeveloper(10.1.3) and then I created an offline database (HR schema)
in JDeveloper from the existing database tables (HR schema). Then I made some updates to the JOBS database table using SQL*Plus.
Then I returned to the JDeveloper tool and refreshed the HR connection. But I found no any changes made to the offline database table JOBS in
JDeveloper.
How to make the JDeveloper's offline tables to be synchronized with the underling database tables?qkc,
Once you create an offline table, it's just a copy of a table definition as of the point in time you brought it in from the database. Refreshing the connection, as you describe it, just refreshes the database browser, and not any offline objects. If you want to syncrhnonize the offline table, right-click the offline table and choose "Generate or Reconcile Objects" to reconcile the object to the database. I just tried this in 10.1.3.3 (not the latest 10.1.3, I know), and it works properly.

Table ZCHECKPICK does not exist in the database
Hi!
I have a table "ZCHECKPICK" no "MANDT - Client".
Then I inserted a field "MANDT - Client" and executed SE14 to "Active and adjust database".
The table is now "does not exist in the database" but the struture is ok.
What do i do to get the table in DataBase again?
<Priority normalized in subject line>
Edited by: Vinod Kumar on Sep 13, 2011 9:32 AMDear Clayton,
you can try a few things
1) generate/activate the table prior to call SE14.
2) after confirming that the table is well generated, go to SE14 and choose "Delete Database Table"
3) then, still on SE14, click on "Activate and Adjust database"
[http://imageshack.us/photo/my-images/607/20110913010743.jpg/]
That should fix it.
Kind Regards

SE14 Status-UPGRADE-Table does not exist in the database
Folks,
I have created a ztable with SPRAS and few Char fields and generated a table maintenance generator.In the Dev it is working fine but when I moved the TR to Q TR ended up with errrors "Generation of Programs and Screens".When I check in Q in SE11 I am able to see the table but with an error message "Table doesn't exist in the database".
SE14 Status for this table is getting shown as UPGRADE in Q.
Can anyone here throw some light on what exactly this status UPGRADE means and how it gets set in SE14.
In DEV,I had checked the DATABASE OBJECT>>CHECK>DISPLAY and RUNTIME OBJECT>>CHECK>>DISPLAY and it is showing Database object is consistent but where as the same in Q is showing "Table is not created in the Database".
K.Kiran.Hi.
Is Q system is newly copied? Also please check the transport order of the table creation request. Also check whether pwd of the DB user is locked?

EMERGENCY: List of files in Recovery Area not managed by the database
Hi,
this is an emergency request....
I have this data guard set up. And i accidently dropped online redo logs, standby logs and the archive log except the current online redolog.
i actually ran to cleanup the whole directory which included the controlfile and the datafiles (was on the wrong location on ASM)
but the controlfile and the datafiles did not get deleted. i can still see them on the ASM.
and now when i am trying to restore the archive logs, but i keep getting error as shown below...
WARNING: A file of type ARCHIVED LOG may exist in
db_recovery_file_dest that is not known to the database.
Use the RMAN command CATALOG RECOVERY AREA to re-catalog
any such files. This is most likely the result of a crash
during file creation.
so when i did the below i was getting error as:
RMAN> CATALOG RECOVERY AREA;
using target database control file instead of recovery catalog
searching for all files in the recovery area
no files found to be unknown to the database
List of files in Recovery Area not managed by the database
==========================================================
File Name: +DATA/afcpdg/controlfile/controlfile01.ctl
RMAN-07526: Reason: File is not an Oracle Managed File
File Name: +DATA/afcpdg/onlinelog/group_1.304.718194815
RMAN-07527: Reason: File was not created using DB_RECOVERY_FILE_DEST initialization parameter
number of files not managed by recovery area is 82, totaling 168.10GB
But i do see those data files that RMAN is complaining as shown above in the ASM.
I HOPE I DID NOT MESS UP THE CONTROLFILE and the DATFILES
CAN SOMEONE HELP ME FIX THIS MISTAKE THAT I DID.
Right now the data guard is running fine, the logs are getting shipped from primary and the getting applied at the DG.
And i am able to see all the redo logs got deleted.
But not sure how the deleted redo logs got created in the ASM (i did not create them manually)
Thanks.
Philip.

Edited by: user8898644 on May 5, 2010 11:43 AMYes this happened on the standby database.
I had to restore the archive logs because i deleted all the archive logs which got shipped from the primary.
I did re-create the standby logs. But when i checked back the redo logs that i deleted came back again.
I have no idea how they can back again. is it a feature of ASM where a mirrored copy of the files are stored on ASM and they re-create them when accidently dropped.
Can you help me understand how the redologs got created again automatically.
Right now the data guard is running fine but i do see the error

Download of files stored in the database
I am using FireFox and my users IE. Download of files stored in the database worked for me but not for my users. I recieve a choice of downloading the file or opening it with a full file name and file type. IE users have some strange behaviour - no name of the file and they can only save it to their local drive - some kind of weird microsoft security option. I was searching for it but couldn't find. Anyone here who would know where to search for it?

Where is the enjoylogo.gif stored in the database
Can anyone tell me where these type of files are stored in the database? Are they in a table?
If you have 2 lists, List A contains custom names, List B has a lookup field that points to List A. I go into list B and select a client name ("Contoso"), enter some info, and save it. On the back end, the list item will contain a value of something like:
34#;Contoso
In this scenario the 34 is the SPListItem.ID value of that item in List A. They start at 1 in each list and increment by 1.
Also, running queries against the database directly is not supported and can take your database out of Microsoft's supportability.
