EA1 - Blank SQL Worksheet

Hello.
MY OS is Win 7 Enterprise 64-bit. I've just installed SQL Developer 4 EA1. I have also installed JDK 1.7.25. 64-Bit, just today. When I open a sql file in EA1, I see the test of the file and I can run the SQL with no issue. However, if I leave that SQL file open, close EA1 and then reopen it, the file window is blank. I see the name of the file in the tab, but the area where the text should be is blank.
Thanks.
Dan

Hi Dan,
Thanks for reporting this for 4.0EA1. I logged a bug titled: 4.0EA1: SQL FILE TAB IS BLANK (NO TOOLBAR, ETC) AFTER SQL DEV REOPENED
Please also note that upon reopening the product, the tab contains no toolbar, connection drop-down box, worksheet or history areas either. One workaround is to click on the Start Page tab, then click back on the SQL file tab -- it repaints with all the expected text and artifacts.
Regards,
Gary

2.1 EA1 - Capitalizing SQL text in worksheet

Whenever I enter some SQL commands in the Worksheet window and press ENTER after the semicolon, it re-formats the text and Capitalizes all keywords. So the following:
select * from dual;
becomes
Select * From Dual;
Which is quite annoying, because SQL Developer shouldn't mess with my code unless I ask it to. I know there is Right-Click -> Format (CTRL-F7), which does a great job fixing messy SQL and I love this feature... but it never used to change the actual text. In v2.1 EA it does, and it uses a different capitalization scheme to that of the worksheet, which results in:
SELECT * FROM dual;
Personally I'd prefer it to behave thus:
1. Don't mess with ANY text in the SQL worksheet, unless specifically asked to do so
2. When formatting SQL with "Format", don't change the case of any text
3. Have another option (or an extension to "Format") that will change the case of text to fit a configurable standard
4. If a block of text is selected when "Format" is invoked, then only format this block, instead of the entire Worksheet window

Sorry if I can't reproduce the exact terms, my windows in in Brazilian Portuguese, but I will try my best.
Latin languages such as portuguese have lots of letters with accents and most accented letters are produced by key combinations. The most common accent in portuguese is the acute accent that can happen with any vowel. To produce an accented vowel, I have to press the single quote key (the one besides enter on a standard American keyboard). By this point, Windows does nothing. Then, if I press <space> I get the single quote and if I press a vowel I get that vowel with an acute accent and if I press a key that doesn't accept acute accent I get a single quote and the character I pressed.
This only happens with keyboard layouts that support such languages with accented letters. I myself use a standard American keyboard on my main workstation and an ABNT approved Brazilian Portuguese keyboard on most others. To set the keyboard layout you go to Control Panel, Region and Language options, Languages tab and click Detail button. If you have a standard American keyboard you should choose United States (International) as the keyboard layout. Now, if you open any text editor (notepad or even the Worksheet editor within SQL Developer) you will notice the behavior I tried to describe above. You must start the software after applying keyboard layout change.
Problem is that Windows will only send the single quote to the active software after it realizes I really want a quote and not an accented vowel. If you open the Shortcut Keys on the Preferences dialog on SQL Developer you will notice that with a keyboard that is set to produce accents is impossible to reproduce <ctrl><quote> and for that reason it doesn't work on the Worksheet editor.
As I said is no biggie change it to something else, but it would be really nice if I didn't had to.
best regards,
Tiago

EA1 - SQL Worksheet automatically commits

I have the checkbox set to NOT auto-commit, but if I do any updates in the SQL worksheet and then disconnect my connection without explicitly committing, the changes are committed to the database anyway.
Thanks,
Richard

Could not replicate, unless your table-save was in response to connection-closeWell... that doesn't make any difference in the end, now does it?
If you first close the table, answering not to commit, the changes stay posted.
Then, later, when you disconnect the posted changes are committed anyway.
Bottom line: there is NO WAY to roll back if you didn't do so explicitly BEFORE closing the table.
What SHOULD happen when you answer NOT to commit, is issuing an implicit rollback. Right?
When connection-closed pending commits happen from driver. That can't be changed.That doesn't need to be changed either.
But what you CAN do is asking to commit or roll back any pending changes when disconnecting (TOAD does so too).
But in worksheet user only knows what they didFair enough.
Nevertheless, as commented on the closed connection, you could ask anyway. I guess a user preference would be the nicest thing to have, so everyone can choose for themselves.
Thanks,
K.

4.1EA2 Text cursor goes missing in SQL Worksheet

In EA1 and EA2, my cursor seems to intermittently go missing in SQL Worksheet
Version info:
$ lsb_release -a

Release: 14.04
Codename: trusty

Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)
(edit: Just tested in Windows - cursor does not go missing)
One such pattern that I noticed it seems to go missing on is when running a script.
Another pattern, if I hit enter a few times before the cursor has a chance to blink in between (not always), or hit the up or down arrow to go to the top or bottom of the page respectively, it also disappears.
I'm able to get the mouse back by dragging the window out of maximize position.
Couldn't reproduce in a procedure editor - assume will be same for package/function editor. So it's most prominent in SQL Worksheet.
Message was edited by: trent I've had SQL Dev closed half a dozen times since reporting this, and now it seems OK. But it does seem to come and go =/

I'm having this same issue that started happening with EA1 and persisted into EA2. It was not occurring prior to my upgrade. My input cursor disappears when scrolling up or down in code using the mouse wheel or scroll bar when the code extends beyond the display area. Moving the window does not help, but resizing the window appears to cause it to redraw and the cursor appears again. I can see what line I am on due to current line highlighting, and I can also select text or start typing to get an idea of where I am.

Hi
Thanks for the response, however even after loading the Default Accelorator preset & then restarting SQLDeveloper, I can't enter anything into the SQL worksheet. Is there anything further I can try (i.e. trashing the prefs etc)?
Thanks for any assistance on this

How to execute procedure in SQL Worksheet ?

Hi, anybody know, how I can execute procedure here?
I try EXEC sec_roles, EXEC security_admin.sec_roles, EXECUTE - there is a SQL statement error. When I use CALL - there is no such procedure (I have execute previleges).
Although in SQLPlus EXEC works, but there are problems with standard SQL commands (all of them returns "2" no matter what content is).
Any ideas?
Regards
Krzysztof

exec procedure(parameters) is a sql plus (and a few others) shortcut for
BEGIN
procedure(parameters);
END;So try that then pressing/clicking whatever it is in sql worksheet that makes a statement run.
Note that if your procedure has parameters defined as OUT or IN OUT, you will need to supply a variable to accept the returned value(s).

SQL Worksheet Gets Slower and S.l..o...w....e.....r with Use

Does anyone else notice the more you use SQL Worksheet, the
slower it gets? The first time I start it up, it'll run a
compile on an object super-fast. After running a dozen or more
compiles and test scripts, I notice it's getting slower.
Eventually, it's so slow I just kill SQL Worksheet and start it
right back up. Then it's back to warp speed again!
I'm on a Win2K machine, running Oracle 8.0.6, with version 1.6.0
of SQL Worksheet.
I have 2.1 install disc for Oracle Enterprise Manager, but I'm
uncertain if I can update what I've got (given the release of
Oracle I'm on). Any help here would be appreciated, too.

The box does not reboot itself at 7am every day at the behest of BT that is not normal behaviour.
I think you really ought to fo a hard reset and clear everything off your hard drive and see if it solves your problem.
If it does not then you are I think looking at a slowly dying box which needs to be replaced.
Factory Reset
Switch off the Vision+ box at the mains socket
Hold down the front panel OK and down arrow buttons
Switch on the power to the Vision+ box
Allow the box to start up (about 15 seconds)
Release the OK and down arrow buttons
The Vision+ box will then contact the servers to get a new copy of its firmware
This will take around 30 minutes

How can I turn off auto formatting whilst working in the SQL Worksheet?

Friends,
Hope you can help with a quick question.
Is it possible to stop the auto formatting of SQL statements in the SQL worksheet?
e.g. When I type select * from dual it auto formats to becomes SELECT * FROM DUAL when I hit return.
I am using SQL Developer 2.1.1.64
Thanks in advance

What happended to "Save As" in the SQL Worksheet?

I am using 14.22 in Windows XP. In the previous version 13.43 I used to:
1) Open a new SQL Worksheet.
2) Type in statements.
3) Press Ctrl-S to save the contents of the SQL Worksheet panel to a new file, an "Open File" dialog appeared.
4) Enter file name for new SQL script file.
Now when I press Ctrl-S I do not get the "Open File" dialog. The Ctrl-S saves the SQL Worksheet contents to a temp file in my user/.sqldeveloper/tmp directory. I have to copy the contents of the SQL Worksheet panel into a text editor and save it to a SQL file. Or I copy the SQL file in my temporary directory to the new file I want.
I saw in another thread that the SQL Worksheet contents is not being saved to a temporary file to help prevent loss of contents if there were a machine outage. This change may have caused this problem.
I use the "Save As" functionality in the SQL Worksheet a lot. That was how I create SQL files.
How do I create a SQL script in SQL Developer now?
Mike

It got dropped by accident but it will be back in for EA7 that we expect to release any day now (just writing the release notes for it now). We have the Save As back in the menu and a right-click Save File from the Worksheet to save your work.

Can't edit in SQL Worksheet

Currently using version 1.1.2.25 Build MAIN-25.79
Yesterday I installed updates and extension for using Subversion.
This morning having started SQL Developer up I am unable to use arrow keys, backspace, return key, delete key, home, end keys in SQL Worksheet. All these keys are available in Microsoft Word so its not the keypad.
Can anyone provide an answer as a matter of urgency.
Thanks.

I would be amazed it if worked. So many differences between SQL Dev and JDev.. not to mention that SQL Dev is built on an unreleased JDev platform. Uninstall that extension and everything will probably go back to normal. You can setup external tools to mimic (albeit crudely) some of the functionality of the extension.

Formatting characters shown in SQL worksheet in version 2.1.1.64

Hi,
Using version 2.1.1.64
When I type SQL in the SQL worksheet is it showing formatting characters - for example all spaces display as a light grey dot and a carriage return character appears at the end of every line.
The formatting characters were not displayed initially when I started to use this version. Ì don't know how this setting got turned on but there does not appear to be a Preferences setting to turn it off. Any ideas?

Tools -> Preferences -> Code Editor -> Display -> Show Whitespace Characters
should take care of your problem.

SQL Worksheet fails to appear in Oracle SQL Developer Version 2.1

I cannot open the SQL Worksheet in Oracle SQL Developer Version 2.1. When I select SQL Worksheet from the Tools menu, a box appears saying that the SQL Worksheet is opening, but nothing happens. After the first attempt, the box does not appear, but again nothing happens.

Thats odd.
Do you see any exceptions in console ? (to see the console launch sqldeveloper.exe in ../sqldeveloper/sqldeveloper/bin dir.)
