SQL Developer Version 3.0.02 really slow to produce results
HelloHoping someone can point me in the right direction here as a SQL Developer on my machine is so slow, that it is virtually unusable (it was not as bad in previous versions but it is possible, that I also have a new JDK since). I open a connection to an Oracle database and the simple type:
Select a_column a_table where a_column = 1
and click on the green triangle (ctrl + enter). The green triangle and the icons of commit / rollback are going gray and I start counting the seconds rough. I arrive at 30 before the result is displayed and I can do anything and yet it says:
All of the lines read: seconds 1 to 0.002
In sqlplus the exact same query returns immediately. I added - J - Dsdev.insight = false to the command line (as it may slow down the Oracle SQL Developer) but this did not help. I'm running Linux Ubuntu 10.10 with
3353400 KB of memory according to cat/proc/meminfo and my ~/sqldeveloper/jdk file contains:
/usr/lib/JVM/Java-6-Sun-1.6.0.24
quality shows:
PID USER PR NOR VIRT RES SHR S % CPU % MEM TIME + COMMAND
8143 martin 20 0 947 m 462 m 28 m S 6:39.68 2 14.1 java
and this is the only java program I am running.
Any ideas?
Thank you
Martin
Yes, there were "dark ages" for the performance of the SQL Dev queries from 30EA1 and 30EA2 (3.0.02).
He said that re-encoding on SQL history was to blame for this.
Unfortunately, there is no satisfactory solution for these versions.
Try at least 30EA3 and better to have production 3.0 a.

MS Access 2010 and Oracle SQL Developer Version 4.0.3.16 error
OS: Windows 7 Enterprise
System type: 64-bit operating system
I can't MS Access 2010 to work/open with SQL Developer version 4.0.3.16.
ERROR when connecting to MS Access 2010 test
"Status: failure Test failed: [Microsoft] [ODBC Driver Manager]" Data source name not found and no default driver specified".

ESCR does not work in SQL Developer Version 1.1.3 build 27,69
Hi all
I'm using Oracle SQL Developer Version 1.1.3 Build 27,69
Select count (*) ABC
count (*)
100
using desc / describe table name gives error
abc desc
ERROR:
---------------------------------------------
ERROR: object that there is no such thing as abc
1 selected lines
I am able to run select on the table but not describe desc. I tried suffixing with the schema name, still the same error persists.
Please provide a workaround solution
TNXWell 1.1.3 is old enough.
The best thing to do IMHO is updated to the latest version, this will also allow a load of new features and fixes.

Can not see the package body in SQL Developer version 3.1
Hello
Have walked the boards and google for that matter for some time now. I think I found the problem, but would like to if there is a work around.
Problem:
I'm unable to view packages, procs, VIEWS DOF, etc. of other users. When one of my colleagues use Toad, with the EXACT same connection ID and the parameter, they are indeed able to see all the source code...
What I found:
Looking around, apparently Toad and SQL Dev work in different ways. Toad a use apparently DBA_SOURCE and DBA_OBJECTS to generate everything.
SQL Dev using package META_DATA to retrieve everything. In addition, in order to use the package meta_data, I need the catalog of grant role, or something like that.
Is it possible to set up the SQL Developer to use the same method as the toad to get the code? It is a fact that I WILL NOT receive the catalogue by the DBA permission... I can write the
Select the text from DBA_SOURCE where OWNER = 'OWNER' and NAME = 'OBJECT NAME';
But I would rather just be able to use the nodes in the tree and click on the objects to generate all this. Anyone know of any setting for this?Hello
No doubt Developer SQL wants to be competitive with the Toad, but in terms of raising red flags on the inconsistencies in the basic features, any difference from SQL * Plus would be more surprising than Toad.
DBA_SOURCE and DBA_OBJECTS are synonymous publicly available in any standard Oracle installation, but you also get to PICK ANY DICTIONARY to get the maximum benefit from them. Which will display the code in the schema of another user without having a privilege explicit (such as EXECUTE) on a function/procedure/package.
If you already have privileges (SELECT ANY DICTIONARY, or EXECUTE or DEBUG on specific executable objects), and the Code tab is empty, you will need to provide a test case, according to Vadim.
With respect to cases where the SQL Developer uses DBMS_METADATA, my understanding is that the API relies on the SELECT_CATALOG_ROLE privilege, if a user has or otherwise have a granted privilege explicitly on an object. Developers like to use this API in the extent possible instead to write a script that could break or need maintenance to deal with future versions of the Oracle database.
I have no idea how works the Toad, and probably I should not speculate, but here's a scenario that might explain the case you mention without that user of connection with one of the above privileges. Let's say that the client software of Toad calls a PL/SQL package that selects from DBA_SOURCE and is installed in a pattern that has the privilege to CHOOSE ANY DICTIONARY. All users of Toad are granted EXECUTE on this package and therefore inherit SELECT ANY DICTIONARY in the execution of the package. It will work, but at the cost of complicating the installation of Toad. Also, he is not giving them a precise control of metadata security administrator.

New versions of Sql Developer not showing do not export progress
Hi, actually I was using SQL Developer to effect considered. The version I used was 3.0.04 and took me to Version 4.0.1.14 in earlier versions of SQL Developer (3.0.04) when I exported the query results that I would see a current account of the number of records exported in the lower left corner of the window. With 4.0.1.14 when I export all I see is a progress bar below on the right with the word 'RUN', but I don't get a count of the number of how many records were exported. Is this something that has been removed from more recent updates of SQL Developer? The account running has been a very useful for large ensemble export, so that we can have a clear idea of the progress of the export. Please any body can advice me how turn on the feature that displays the number of records exported.
View > Task progress will show you a number of records running for your exports

Reset preferences in SQL Developer 4 using the older version of EA
SQL Developer (Version 4.0.0.13 - main build 13.80) and RDBMS 11 GR 2
I used the version (s) EA of SQLDEV4 for the past few months. Yesterday, I downloaded and installed the new version of SQLDEV 4 production. Unfortunately, when the installer asked if I would like to "see" my preferences from an earlier version of SQLDEV new SQLDEV4, I chose the wrong version of EA.
Is there a way to reset the preferences in new SQLDEV4 to get preferences from a previous version of (EA) or am I stuck trying to remember all the preferences, I put the last few months. I am tired of the reinstall, but preference 'Report' question never asked again.
Thanks in advance.

Close SQL Developer. Go to your application under user settings directory - this being windows mobile - blow the directory for this install v4.
Re-run the EXE file, it prompts you to new to the thread.

How can I use sqlldr on SQL Developer version 4.0.2.15 command.
Now I'm able to use this command via the command prompt, but my requirement is that use this command on SQL Developer.
SQL * Loader is an external standalone tool, not a SQL or PL/SQL command.
Ask how to run through SQL Developer, that's like asking the execution of MS Word through SQL Developer, i.e. it is not really meaningful.
SQL * Developer, to the best of my knowledge, incorporates some built in options for loading data or extraction of data to CSV files, so maybe you want to just use those?

SQL * more the 'timing' in SQL Developer command
I installed SQL Developer version 4.1.1.19. In the sql worksheet, how can I use SQL * more order 'timing' in a script to see a time elapsed SQL? The "Timing" on 'set' did not return any info after running SQL, and 'calendar beginning mon_timer' back 'command Timing is obsolete. Help, please.
Thank you
- As you can see, there is no calendar information in the script output log.
- Then I tried on the discussion forum, found it can be enabled in "tool > preference > Database > startup script" and set as startup script:
Set serveroutput on
set timing on
- However, 2 questions are:
- the calendar that he returned is NOT the elapsed time of my stored procedure to run. He simply choose the 2 time points its time, before and not after MS point run. Set timing on is therefore not a solution for me.
- He did not follow the instructions in the startup script. After that I put the calendar in the startup script, stop & restart SQL Developer, same laptop charging, timing still on. The only way to turn off now is to configure it to NOT use
any startup script.
- Then I developed my own coding as a solution:

SQL Developer debugger does not start
I found a strange behaviour, while debugging PL/SQL stored procedures using SQL Developer version 4.1.0.19 on Ubunto 12.04 LTS. The debugger works fine for all the bases of my company, except one. When I start a debugging session in this database, the debbuger let go forever and never debug dialog box open. When I use another IDE, for example, PL/SQL Developer of AllroundAutomations on Windows 7, the debugger works very well. I used the same user database with all necessary Preobrajensky. First I thought it was a bad configuration of the database, but as I could start with another IDE debugging sessions, I think that this is not the case. So, I would like to know if someone could help me understand what is happening.
We opened a request for support at Oracle and they offer us to turn on an earlier version of the debugger to work around the problem:
Add at the end of the file line-by-line ide.properties:
DatabaseDebuggerDisableJDWP=true
The ide.properties file can be found here (on Windows XP):
C:\Documents and Settings\
${VERSION} \o.sqldeveloper\Application Data\SQL Developer\system ${SYSTEM_VERSION}
or here (on Windows 7):
C:\Users\
${VERSION} \o.sqldeveloper.\AppData\Roaming\SQL Developer\system ${SYSTEM_VERSION}
for Linux users:
$HOME/.sqldeveloper/system${VERSION}/o.sqldeveloper.${SYSTEM_VERSION}/ide.properties
It works!

How to modify data in "Result grid query" in Oracle SQL developer
Dear,
I would like to know how to change values directly in the query result grid.
I use Oracle SQL Developer version 4.0.3.16
Thank you
Khalil
I checked in SQL Developer 4 and I found no option to do this.
I don't think it's available. You can open the table and add filters on each column and change. Or you can add where clause as suggested the link written by Jeff that I already gave. (http://www.thatjeffsmith.com/archive/2013/06/sql-developer-im-looking-at-a-record-how-do-i-edit-it/)
Or you write update instructions.

Unit test in sql developer 4.1 fails but passes in 4.0
I can't tell if it's a question of Java or Sql * developer issue.

Versions of Java: Tried jdk 8: 1.8.0_5, 1.8.0_20 and 1.8.0_31 - all 64 bits
That is the message in the response of unit test:

However, there is no report in the command window after a ctrl-pause/break. At the same time, however, it is not like sql * developer hangs here.
Thoughts?
EA 4.1 includes a new feature to save all JDBC calls (view > Log, and then note the statements tab in the logs pane), so it could be the difference in the behavior of Test Unit between 4.0 and 4.1.
You use the JDBC default 12.1 driver, or you have overridden by specifying a particular Oracle client? In other words, in
Tools > Preferences > Database > advanced > use Oracle client > configure...
I read that somewhere there may be problems when you use the clients pre - 12 c with earlier versions of JDBC. driver
