SQL line wrap in editor

Hi - I'm new to sqsl developer. How do I make my code wrap to the next line instead of going straight across the page. ?
I'm using version 1.5.5

Sorry, that's not possible unless you format the code (F7 or context menu).
FYI, version 2.1.1 has a lot more formatting options in Preferences - Database - SQL Formatter - Oracle Formatting.
Have fun,
K.

Line wrap in Editor

Is it possible to have the editor view wrap lines? Long lines go off the screen and I have to use the horizontal slider to see them. I want a long line to wrap in the editor.

Never mind. I found my answer in another post named "Word Wrap".

How to add new line wrapping rule?

Hi all,
I have a question about line wrapping condition of Java editor of JDeveloper.
JDev has some predefined rules for it and I can change them from preference.
But can I add a new rule?
I'd like to place conditional operators such as "&&" or "||" at head of line.
For example, as below.
if (values[0].length() > 2
&& values[1].length() == 3
|| values[2].length() < 10
&& values[3].length() == 0) {
JDev doesn't seem to have the predefined rule about conditional operators.
So I'd like to know if I can add new one.
My Jdeveloper is 11.1.1.6.0.
Thanks,
Atsushi

Atsushi,
I don't think you can add a new rule there.
However, how about setting Line Wrapping->Binary Operators and Assignments to Always? Your code would then look like
       if (values[0].length() >
            2 &&
            values [1].length() ==
            3 ||
            values [2].length() <
            10 &&
            values [3].length() ==
            0 ) {

Creating Packages from BLOB field contents, line wrap problems

Good afternoon,
we use an in-house developed database-driven update system to update both our databases and filesystems, the system itself performs really well but there is still one problem I can't fix without some expert help:
the code of to-be-updated Oracle packages is stored inside of a BLOB field, the BLOB field will contain both the package specification and package body and needs to be split into two parts to first execute the spec and then to execute the package body (I tried to execute both in a single step but this didn't work). This works for packages with less than 32767 characters and also works in some other cases but I found one case where the executed code contains an extra line wrap right in the middle of a word.
To make it more clear (I hope it's comprehensible), imagine the following database content:
CREATE OR REPLACE Package
MyPack
AS
[... a lot procedure headers ...]
END MyPack;
CREATE OR REPLACE
Package Body MyPack AS
[... a lot more procedures ...]
PROCEDURE myTest (intID OUT integer)
AS
BEGIN
SELECT count (*) into intID FROM MyTa[--this is where the dbms_lob.substr() ends --]ble;
END;
END MyPack;My code searches for the second occurrence of the "Create or replace package", splits the code into spec and body, executes the specification and keeps on adding the rest of the code to a VARCHAR2A variable called "storedCode" from the BLOB. Now in the above example, after the specification has been removed from the string, the remaining characters (ending with the "MyTa" string) are added to the varchar2a variable, the next line is fetched from the BLOB via "dbms_lob.substr()" and added as long as dbms_lob.substr() does not return a NULL value (end of BLOB). When the code is executed after all has been fetched, the generated Package Body will contain an extra line wrap right in the middle of the "MyTable" word compiling the package invalid.
This is the procedure code I use (definitely improvable, I'm better in MSSQL and MySQL dialects ...) to load, parse and execute the BLOB content:
   -- to run package code
procedure runPackageCode (stepRef integer)
AS
    numLines integer default 1;
    pos     integer default 1;
    storedCode    LOG_CHANGEDOBJECT.STOREDOBJECT%type;

Good, clear problem statement. So why doesn't your code do just what you said it should do: 1) split the code into two parts, 2) execute the spec and 3) execute the body.
Instead of writing code that does these three relatively simple steps your code tries to combine splitting and executing and mushes/mashes it all together. The result, as you found, is code that is hard to understand, hard to debug, doesn't work and doesn't report on what it is doing.
Code like this doesn't have a performance issue so the code should implement the simple step-by-step process that you so elegantly stated in your problem description:
1. split the code into two parts
2. execute the spec
3. execute the body
My advice is to refactor your code to perform the above steps in the proper order and to add proper exception handling and reporting for each step. Then when a step isn't working you will know exactly where and what the problem is.
Here are my recommendations.
1. Add two CLOB variables - one will hold the spec, the second will hold the body
2. Add a comment (you have some good ones in the code now) for every step no matter how trivial it may be
3. Add exception/error handling to EVERY STEP
Your code for the first step has a comment but no exception handling. What should happen if you don't get any data? Why aren't you validating the data you get? Dynamic SQL using table-driven data is great, I love it, but you MUST validate that the data you get is what you expect to get.
    -- retrieve update ID
    SELECT log_update_ref INTO currentUpdate FROM link_update_with_taskstep WHERE log_taskstep_ref = stepRef;Recommended
    -- step 1 - retrieve update ID - This is the id that determines BLAH, BLAH, BLAH - add appropriate to tell a new developer what this ID is and what it means.
    BEGIN
        SELECT log_update_ref INTO currentUpdate FROM link_update_with_taskstep WHERE log_taskstep_ref = stepRef;
    EXCEPTION
        WHEN ??? THEN -- what should happen if step 1 fails? Do it here - don't default to an exception handler that is several pages away.
    END;Your code
     begin
        select storedobject, change_area
        into storedCode, schemaReference
        from vw_storedobjects
        where step_id = stepRef;
     exception
      when no_data_found then
        pIsError := 1;
        pErrorMsg := 'Invalid SQL ID ' || stepRef;
        pkg_generic.LogError(updateRef, 'LocalUpdater', stepRef, 'Run package code failed: ' || pErrorMsg);
     end;
Good - except there is no comment that says what this does - I assume that the query above and this block are the 'retrieve update ID ' step?
You log an error message and set the error flag to '1'. But since you don't want to continue why aren't you exiting the procedure and returning right here?
      if pIsError = 0 then
        beginSo now you check the error flag and do several pages of code if there were no errors.
I don't like that 'inverted' logic.
If you don't want to continue then STOP right now! Don't make a developer scan through pages and pages of code to find out you really aren't doing anything else if there was an error.
Either put a RETURN statement in the exception handler above or change your code to
      if pIsError = 1 then
        RETURN;
      end if;Now the rest of the code doesn' t have to be indented; you will never get there if there is an error. Check for errors after every step and exit right then as appropriate.
          -- change schema
          execute immediate 'alter session set current_schema = ' || schemaReference;
          objectCursor := dbms_sql.open_cursor;
          loop
            strLine := UTL_RAW.CAST_TO_VARCHAR2(dbms_lob.substr(storedCode, 32767, pos));
            intDelimiterPos := regexp_instr(strLine, '\s*Create\s*or\s*Replace\s*Package', 2, 1, 0, 'i');
            while intDelimiterPos > 0
            loopThis code mixes all of the steps together into one giant mess. You open a cursor, try to split the BLOB into spec and body and try to parse and execute both all within a double nested loop.
Even if that works correctly another developer will have a hard time understanding what the code is doing and fixing it if it goes wrong. And it will go wrong if you let me test if for you because I will put garbage into the BLOB for the spec, body or both to make sure it breaks and to see how your code handles it.
I suggest you rewrite this double nested loop to perform the three steps separately.
1. split the code into two parts
a. put the spec into one new CLOB variable and the body into the other.
b. use DBMS_OUTPUT (or a work table) to output the spec and body so you can see what the code is and make sure the 'split' process worked properly. You probably created that BLOB by manually concatenating the SPEC and BODY to begin with so now create a SPLIT process to split them again and give them back to you. This is such a fundamental component that I suggest creating a new SPLIT_MY_BLOB procedure. This procedure would take a BLOB and return two CLOBS as OUT parameters: one CLOB is the spec and one is the body. Then you can reuse this 'split' procedure in other code or more complex versions of code. Modular programming is the key.
2. execute the spec - Now have a step that executes the spec and does something appropriate if the step succeeds or if it fails. I mean, do you really want to do execute the body if the spec execution fails? What do you want to do? Should you delete the body and spec? If you don't you might wind up with an INVALID body based on old code and an INVALID spec based on the new code you were trying to use. How will anyone, including you, know that the spec and body in the ALL_SOURCE view is really two different versions of things?
This suggests that for your use case you may want to consider DROPPING the entire package, spec and body, before trying to recreate them both. At least if the package is totally missing anyone will know that the entire thing needs to be put back. Ahhhh - but to do that you need to know the package name so you can drop it. Than may require adding another step to get the package name from your data-driven table and adding a DROP PACKAGE step.
3. execute the body - This step executes the body. Hmmmm - we have two nearly identical steps. So why don't you create a new function/procedure that takes a CLOB as input, uses dynamic sql to execute it and returns a result code. That would be useful. Then you could execute ANY sql stored in a CLOB and have a generic function that you can use for other things.
Right now you are using the VARCHAR2 table version of DBMS_SQL.PARSE but you would change this to use the CLOB version.
The end result of this refactoring is a main function/procedure that acts as the CONTROL - it decides what to do and what data (BLOB) to do it with. But it doesn't actually do ANY of the work. It just controls what is done.
And you have a couple of generic, reuseable functions that actually do the work. One knows how to split a CLOB into spec and body. The other knows how to use dynamic SQL to execute a CLOB.
Now you have a modular architecture that is easy to understand, easy to code and easy to test.

Line wrapping and scrolling in JPanel

Hello,
I've got an empty JPanel to which I want to add an (unknown) number of JLabels. Each JLabel has a text which is just one word. When my program is adding JLabels to the JPanel, I want it to have the same behaviour as a normal text editor: when a line is full, the next line gets filled (line wrapping).
If I just keep adding JLabels to a JPanel of a fixed size with .add(), there's no line wrapping. I tried it by giving the JPanel a fixed size, flowLayout and nesting it within a JScrollPane, but it keeps filling one long line, instead of jumping to the next one.
Any obvious solutions??
Thanks
Mark

well this depends on how your layout is build, you should post some code so we can see what your trying to do.
For example if your JPanel is the Frame's main panel, fixing a MaximumSize or PreferredSize wont have any effect, it will grow as big as you defined the JFrame size.
If you have only a JPanel with a max size of 200,300 in a JFrame with a size of 800,600, it will grow to 800,600.
You could create a BoxLayout with X axis, then insert an HorizontalStruts, insert your JPanel and another Horizontal Struts(Box.createHorizontalStrut(int width) ) to force the JPanel to be smaller than the JFrame.
I did not test this a lot, but it seams to work
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Test {
public static MyFrame frame ;
public static void main(String[] args) {
    frame = new MyFrame();
    frame.show(true);

    JLabel a, b, c, d, e, f, g, h, i, j, k ;

      super();
      JPanel sizeLimiter = (JPanel)this.getContentPane();
      sizeLimiter.setLayout(new BoxLayout(sizeLimiter, BoxLayout.X_AXIS));
     // sizeLimiter.setPreferredSize(new Dimension(800,600));
      JPanel mainPanel = new JPanel();
      mainPanel.setLayout(new FlowLayout());
      mainPanel.setPreferredSize(new Dimension(400,300));
      mainPanel.setMinimumSize(new Dimension(400,300));
      a = new JLabel("this is sample test ");
      b = new JLabel("to demonstrate an example ");
      c = new JLabel("of simple a flow layout ");

      e = new JLabel("when it reaches the end ");
      f = new JLabel("of a line. ");
      g = new JLabel("Set the maximum size of the panel ");
      h = new JLabel("And it should work ");
      i = new JLabel("If it doesnt post your code so we can");
      j = new JLabel("check it out to see whats wrong ");
      k = new JLabel("sincerly yours, Jf Beaulac ");
      mainPanel.add(a);

      mainPanel.add(j);

      // Fix some "margins"

      // Squeeze the panel
      sizeLimiter.add(mainPanel);

      if (e.getID() == WindowEvent.WINDOW_CLOSING) {
        this.dispose();

Line wrap in JSE 8

Hi,
Is there a way to wrap around long line on the editor? I don't want a hard wrap, just a soft wrap around the window. Couldn't find any such option.
Thanks.

Hi Jin_B,
Thanks for the tip. I did install NbCheckstyle in JSE8, but I didn't quite understand how to actually get it to work. After reading doc etc., this is what I did:
I set the following as the config file:
----CheckStyle.xml-------
<module name="Checker">
     <module name="TreeWalker">
          <module name="LineLength">
          <property name="max" value="120"/>
          </module>
     </module>
</module>
This resulted in the following error:
An error occurred during initialization.
Make sure there is a configuration file set under Tools->Options->Building->Checkstyle Settings
com.puppycrawl.tools.checkstyle.api.CheckstyleException: unable to parse C:\Program Files\Programming Tools\JStudio\ide\CheckStyle.xml - Document is invalid: no grammar found.:1:8

Any pointers?

Code Style - Line Wrapping - JSPX files

JDeveloper 11.1.1.0.2
I've got my Line Wrapping Line Width set to 180 and this works for my Java code but not for my JSPX files, which continue to break at 80 columns. In previous releases of JDeveloper my JSPX code would also wrap at 180, but I cannot remember what I did to make that happen. Can anyone give me a hint?
Thanks, Mark

Cannot Open SQL from Data Prep Editor (SQL Interface)

Hi,
When I Open SQL in Data Prep Editor: "There are no data sources defined. Please create one to continue."
I create a ODBC connections using the drivers bellow and I obtain always the same message ("There are no data sources defined.."):
Oracle in OraDb10g_home2
Microsoft ODBC for Oracle
MERANT OEM 5.2 32-BIT Oracle
I have installed and configured Essbase, release 11.1.1.2
Is posible that the SQL interface is not installed and configured with the Essbase Server?
How I can install and configure the SQL Interface? I need to do somethink else?
Thanks!
Assia

Through EAS select the server and right click and select properties. then go to the environment tab(I think) it should show everything you are licensed for. If this is a System 9 or higher, you should have it automatically. If it is 7X or below,then yoes it has to be licensed

SQL Error in Query Editor

Hello All,
I am new to the Sun Java Studio Creator and in the tutorial Linking Components to Data tutorial.
I created my own datasource which is a MS Access database.
I have a simple look up table and I dragged the table onto the dropdown list as instructed and nothing happened. The dialog box the tutorial said would appear didn't appear.
So I right clicked on the rowset added on to the page to get in the Query Editor.
When opening the Query Editor, I get an error:
Error Connecting to Database:
java.sql.SQLException:[Microsoft][ODBC Driver Manager] does not support this function
The SQL reads in the editor is something like this:
SELECT ALL tableName.Column 1 FROM tblName
Why does it automatically put the "All". Is that standard SQL? I don't think so. But I guess I could be wrong.
I have not seen this used in other SQL. I've used T-SQL, PL/SQL, ACCESS SQL and never had I seen the "ALL" preceding the columns of the table.
Quite frustrating when something as simple as a simple SELECT statement does not work when you're trying to learn a new tool.
When adding the datasource, the test connection is fine. The query editor sees all of my tables in the MS Access database and all of the added table's columns.
Am I missing a driver, or update to a driver? Or is this Sun's way of saying "Screw Your Microsoft database use something that we want you to use!!"
Which is not pretty cool.
I'm a newbie with this tool, but I have been coding for a while using MICROSOFT products. And have not had the same problems as this. Or at least getting help through documentation.
I'm just venting here. I want to learn this tool. And when simple processes doesn't work. And documentation in why it's now working is hard to find, it gets quite frustrating.
Anyone's help would be greatly appreciated.
I truly appreciate your time for reading through my frustration.

Hi,
Please check the driver and also take a look at the link for "Supported Database Servers and JDBC Drivers"

How to prevent automatic line wrapping in a JEditorPane

I have added a JEditorPane inside a JScrollPane which is inturn is added inside a JPanel with a GridLayout.
While JEditorPane is loaded with an HTML page or a html file is read into it with an HTMLDocument the longer lines are geting wrapped automatically to the next line when the display area of the parent component of the JPanel where the original JScrollPane is held (like the JFrame or JSplitPane etc.)
It doesn't help even after seeing a preferredsize/maximumSize or minimumSize
of the JEditorPane (b'cos it defaults to some other size which i'ven't set at all).
The horizontal scrollbar apperas only the when the the JEditorPanes size is reduced lesser than its defult size which has been set (probably by the layout manager).
I want to get rid of this behaviour of the JEditorPane such that horizontal Scollbar should apper as soon as the user reduce the size of the window displaying the above component hierarchy (parent container->JScrollPane->JEditorPane) and no line wrapping occurs.
Note : 1. JEditorPane doesn'y have linewrapping API like JTextArea
2. Its default and automatic linewrapping behaviour is conforming
with word line wrapping where lines are broken at the end of a
word which can be fully accomodated.

Problems with JTextPane line wrapping

Hi to all.
I'm using a code like this to make editable a figure that I paint with Java 2D. This JTextPane don't has a static size and for that, the text in it cannot be seen affected by the natural line wrap of the JTextPane component. The problem is that I have to set a maximun size for the JTextPane and I want to use the line wrap only when the width of the JTextPane be the maximun width. How can I do this?
public class ExampleFrame extends JFrame {
    ExamplePane _panel;
    public ExampleFrame() {
        this.setSize(600, 600);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        _panel = new ExamplePane();
        getContentPane().add(_panel);
        this.setVisible(true);
    public static void main(String[] args) {
        ExampleFrame example = new ExampleFrame();
    public class ExamplePane extends JPanel {
        public ExamplePane() {
            this.setBackground(Color.RED);
            this.setLayout(null);
            this.add(new ExampleText());
    public class ExampleText extends JTextPane implements ComponentListener, DocumentListener,
            KeyListener {
        public ExampleText() {
            StyledDocument doc = this.getStyledDocument();
            MutableAttributeSet standard = new SimpleAttributeSet();
            StyleConstants.setAlignment(standard, StyleConstants.ALIGN_RIGHT);
            doc.setParagraphAttributes(0, 0, standard, true);
            this.setText("Example");
            this.setLocation(300, 300);
            this.setSize(getPreferredSize());
            this.addComponentListener(this);
            getDocument().addDocumentListener(this);
            this.addKeyListener(this);
        public void componentResized(ComponentEvent e) {
        public void componentMoved(ComponentEvent e) {
        public void componentShown(ComponentEvent e) {
        public void componentHidden(ComponentEvent e) {
        public void insertUpdate(DocumentEvent e) {
            Dimension d = getPreferredSize();
            d.width += 10;
            setSize(d);
        public void removeUpdate(DocumentEvent e) {
        public void changedUpdate(DocumentEvent e) {
        public void keyTyped(KeyEvent e) {
        public void keyPressed(KeyEvent e) {
        public void keyReleased(KeyEvent e) {
}Thanks for read.

I'm working hard about that and I can't find the perfect implementation of this. This is exactly what I want to do:
1. I have a Ellipse2D element painted into a JPanel.
2. This ellipse is painted like a circle.
3. Into the circle there's a text area, that user use to name the cicle.
4. The text area is a JTextPane.
5. When the user insert a text area, it can increase it size, but it can't be bigger than the circle that it contains.
6. There is a maximun and a minimun size for the circle.
7. When the user write into de JTextPane, it grows until arriving at the limit.
8. When the JTextPane has the width size limit, if the user writes more text into it, the JTextPane write it into another line.
9. The size of the JTextPane has to be the optimun size, it cannot have empty rows or empty lines.
This code does all this except 9, cause if the user remove some text of the text area, the form of the JTextPane changes to a incorrect size.
public class ExampleFrame extends JFrame {
    ExamplePane _panel;
    public ExampleFrame() {
        this.setSize(600, 600);

                    Dimension size = getSize();
                    Dimension preferred = getPreferredSize();
                    if (size.width < MAX_WIDTH) {
                        size.width += 10;
                    } else {
                        size.height = preferred.height;
                    setSize(size);
            SwingUtilities.invokeLater(doRun);
        public void removeUpdate(DocumentEvent e) {
            this.setSize(this.getPreferredSize());
        public void changedUpdate(DocumentEvent e) {
        public void keyTyped(KeyEvent e) {
        public void keyPressed(KeyEvent e) {
        public void keyReleased(KeyEvent e) {
}I know that the problem is into the removeUpdate method, but I have to set to the JTextPane, allways the optimun size, how can I do this?
Thanks to all.

Center text in a text component with line wrapping

I need to display dynamic text in a text component. I need line wrapping (on work boundaries) and also need horizontal and vertical center alignment.
How do I do this? I saw a previous post on aligning text in a JTextArea that said to use a JTextPane but I don't see in JTextPane how to do word wrapping.
Thanks,
John

Line wrap in JTextPane

I didn't see a setLineWrap(boolean) method in JTextPane (as you can tell from my previous posts I'm having trouble going from a JTextArea to a text component that can format text). How would I force it to line wrap like a JTextArea would if you called
tp.setLineWrap(true);
tp.setWrapStyleWord(true); ?
I've set the JTextPane in a JScrollPane, so I'm worried it will not wrap.
thanks for the info.

I just finished some testing and it seems the the line wrapping is set to the way I wanted by default, ie by just like I had called the above methods on a JTextField
thanks

Line wrapping in Java??

Hi,
Can anyone tell me if there is a class to handle line wrapping in Java?
I'm working on a Java Mail application that deals with fairly lengthy email message bodies. The problem is in the actual email, the message body appears in a lengthy horizontal single line which is rather inconvenient to read.
I'd like to break the message body into convenient 80 character lines that takes word boundries into account so that there are no broken words at the end of a line.
Thanks,
Veena

Well the easiest way would be to put line breaks when you want them.
"\n" is the line break character.
So String("aaaaa\naaaaa");
Should appear as
aaaaa
aaaaa

HTML lines wrap around in the HTML report output

I seem to have a problem with lines wrapping around in HTML format. If the report is ran using the report builder the output will fit in every line without wrapping the information.
While if I run the same report -- to present the info using a browser -- using JSP in HTML format, the same lines will wrap around the info in two lines.
Here is how I send this document to the server :
pwrmpos_n: report=pwrmpos.rep destype=cache desformat=html server=rep60_wforms2 %*
Any help will be appreciated

Hello Hernando,
I am a little confused, the command that you describe is only for paper layout...
Anyway, let's try to help you:
- on your paper layout you specified a width for each column (when you resize it in the Paper Design window). When you run the paper layout with HTML (ot HTMLCSS) as format the width is present in the <TD> tag.
- for the JSP, by default the HTML does not contains any size for the table and cell so the browser size the table to fit in the screen.
If you do not want any wrapping in the JSP just modify the HTML tags to specify a width, or wrap for the TD tag.

Tugdual
