Oracle SQL Developer Cannot Cancel Queries Properly

This was a problem with version 2 and continues to be an issue with version 3. If I chose to cancel a query that is taking a long time to run it gives me the prompt and displays that the query was cancelled. However, the query is not actually cancelled and is still running in the background. The lock on the table still exists. How can I tell? Once a query is cancelled I attempt to exit the program and when I try to disconnect it says that the connection is busy. My only options are to try again or abort. First of all, these are terrible option names. How about changing these to try again or cancel, which is actually what abort does. Second, at this point there is no way to exit the application until the query completes in the background. I can kill the application through the Task Manager which in turn kills the query. This is a major problem and needs to be fixed before this application is useful.

I also am having this same issue. I am running SQL Developer 2.1.1.64.45 (JDK 1.6.0_11), connecting to Oracle 9.2.0.4.0 via TNSNAMES.
Seems to be similar to this thread: http://forums.oracle.com/forums/thread.jspa?messageID=9524997&#9524997
In which it appears to be a genuine bug.. Since I develop large queries in SQL Developer before sending them through a SAS program via PROC SQL, I have no other way to test them. It is frustrating, when testing the large queries, to have to do CTRL-ALT-DEL to delete the SQL Developer task and therefore losing any other query tab changes I have made before running/canceling the task. Grrrr.. :)
Thoughts? -Kristi

  • Configuring RAC-aware JDBC connection in Oracle SQL Developer?

    How can Oracle SQL Developer be configured to properly connect to an [Oracle RAC|http://en.wikipedia.org/wiki/Oracle_RAC] environment, I.E., not just setup to always connect to one of the individual nodes?
    [http://programmersjournal.blogspot.com/2008/08/jdbc-connection-string-for-oracle-rac.html] has an example of a classic and the equivalent RAC-aware version of a JDBC connection string. I've already been using a RAC connection string of the same format from within custom Java applications without issue. I thought the same should be configurable in Oracle SQL Developer by setting the "Connection Type" drop-down to "Advanced", then entering the RAC-aware JDBC connection string as the "Custom JDBC URL". However, upon testing the connection, the following error is displayed at the bottom of the dialog:
    Status : Failure -Test failed: Io exception: NL Exception was generated
    There is no additional information shown on the "Logging Page" view. Using Oracle SQL Developer 1.5.5.
    Thanks!

    Thanks, Barry. Just F.Y.I., it is working for me now that I upgraded to the 2.1 EA as -K- suggested. I had marked his reply as "Correct", but probably should have left a response indicating my success as well.
    Now, if there's anything you could do regarding the [issues around the display performance of CLOBs, etc., in the Query Result view|http://forums.oracle.com/forums/message.jspa?messageID=3906571] , it'd be very appreciated!

  • Running Stacked Queries in Oracle SQL Developer

    Is it possible to run stacked queries in Oracle SQL Developer???
    Something like this...
    SELECT *
    FROM TABLE_1
    SELECT *
    FROM TABLE_2
    SELECT *
    FROM TABLE_3
    And give my 3 different result sets in my Query Result window
    I tried "BEGIN" and "END" and Oracle SQL Developer did not seem to like it.
    Can someone let me know if this is possible and what the syntax might be???
    Thanks in advance for your review and am hopeful for a reply.

    Wrong forum!
    Please post this in the sql developer forum.
    SQL Developer
    You can run multiple queries exactly the way you posted them but you need to use F5 - the run script toolbar button.

  • Getting the schema using Oracle SQL Developer 1.5.1

    I need to generate a report in CSV/XLS format using Oracle SQL Developer 1.5.1 to get the schema details
    in the below format.
    Table Name: XXXXXXXXX
    Table Space Name: XXXXXXXXXXXXXXX
    Structure :
    Field Name Data Type Size
    Xxxxxxxx xxxxxx xxxxx
    Xxxxxxxx xxxxxx xxxxx
    Xxxxxxxx xxxxxx xxxxx
    Xxxxxxxx xxxxxx xxxxx
    Field level constraint:
    Xxxxxxxxxxxxxxxxxx
    Table Level Constraint:
    Xxxxxxxxxxxxxxxxxx
    Indexes:
    Index Name Column Name(s) Table space name
    Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
    Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
    Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
    Sequence Number:
    Xxxxxxxxxxxxxxxx
    Triggers:
    Xxxxxxxxxxxxxxxxxx
    I am using a query to do that, but I cannot run more than one queries in the Create Report Dialog.
    I went to the Menu->View->Reports. In that, I chose User Defined Reports, created a new folder called Schema Detail and in that a report named Schema Detail. I right click on that report, choose Edit option, Create Report Dialog opens.
    In the Create Report Dialog, I chose the option Script for Value of Style.
    In the SQL column I enter a query "select * from table_names". But, if I enter another query after that, it does not run and reports an error "SQL Error: ORA-00933: SQL command not properly ended
    00933. 00000 - SQL command not properly ended" Cause:    Action: "
    I end the first query with a semi colon, but it does not work.
    The queries run fine in a SQL Worksheet. There, I can terminate the first query with a semi colon and enter the second query. Then, I run both of them together so that result-set of second query appears after the second.
    Am I doing something wrong? Can someone please advise on how to get the information I need?
    Thanks a lot.

    You can do it in SQL Worksheet because you are running a script. You could run the script in SQL*Plus, and even start it from a bat/cmd file.
    Or if you want this as a User Defined Report, you might make it a PL/SQL style report. Here, all output is done through DBMS_OUTPUT.PUT or DBMS_OUTPUT.PUT_LINE. You can output HTML tags or plain text. I have an example in my paper for ODTUG Kaleidoscope 2009.

  • Data Transformation Service (DTS) available in Oracle SQL Developer?

    Hi All,
    Sorry to bother you again. Is Data Transformation Service (DTS) available in Oracle SQL Developer? So far I cannot find it. For example, i want merge First Name, Last Name column from Access,excel or cvs to migrate as Full Name in Oracle or Full name in Access,Xls or cvs split into First name & last name column in Oracle. What method or service should I use.
    Regards,
    Tun Tun

    On wikipedia, I see that's a SQL Server component, so I don't think it's possible to use it in any other program.
    But you can always tweak columns through normal queries, and even create a new table based on that, like
    CREATE TABLE Table_New AS
    SELECT First_Name || Last_Name FROM Table_OldHope that helps,
    K.

  • Oracle SQL Developer  error - "The file-based source procedure Name is not present in the database."

    I recently started working on the Oracle SQL developer. I have 'select' privileges on the QA schema and when tried to execute proc in QA. It is giving the error as 'The file-based source <procedure Name>  is not present in the database.  Was it compiled?'
    instead 'you do not have sufficient privileges to execute this procedure'. Did research on internet but with no luck.What configuration changes needed to be done to make it work.Guide me.

    Sounds like you do not have the correct privileges.  What should have been granted to you by the QA user, or some other user with appropriate privileges, is...
    grant EXECUTE on "QA"."<PROCEDURE_OF_INTEREST>" to "<YOUR_USERID>" ;
    Note that a grant of execute on a procedure has nothing to do with grants of select on some or all of QA's tables and views.
    So, as Vadim suggests, from your connection node in SQL Developer's Connections view, if you expand the Other Users node, then expand QA and look in the Procedures node, do you see the procedure of interest?  If not, you cannot expect to be able to execute it from your userid's connection. And even if you do see it, you may have some other privilege that permits viewing but not executing, like...
    The role SELECT_CATALOG_ROLE
    The system privilege SELECT ANY DICTIONARY
    And even if you do not see it there, then having certain other privileges granted to you could permit executing it in general, like...
    The role EXECUTE_CATALOG_ROLE
    The system privilege EXECUTE ANY PROCEDURE
    Also, note that the 3.0 release is a bit dated nowadays. Upgrading to 4.0.3 production or even the 4.1 EA2 (early adopter) release will, in general, give you a better experience.
    Best wishes,
    Gary

  • Oracle SQL Developer to be used in laptop

  • Unable to display results of multiple query in grid in Oracle SQL Developer

    Hi, I am a newbie to this forum and couldn't find the Oracle SQL Developer forum so posting it here.
    My question: How to display multiple query results in grid in Oracle SQL Developer.
    Example:
    select * from Employee;
    select * from Department;
    - when I select both the queries and hit F5 in Oracle sql developer. By default it displays in output window.
    - How to display result of both the queries in Grid.
    Any thoughts on this would be really helpful.
    Thanks in advance.
    Harsh

    Hi Harsh,
    I'd say that the Results grid is designed to only show the results of 1 query at a time. I don't know/can't see how it would display multiple queries at a time.
    I would suggest either joining your tables to create a single query or opening another SQL Worksheet for one of the queries so that you can display the results side-by-side.
    Maybe you could explain what you're trying to do. Why are you trying to display multiple results in the same query grid?

  • "Explain Plan" in Oracle SQL Developer is greyed out

    Hi all,
    I know this is not the right place to post this, but I have look around and do not know where to post question about Oracle SQL Developer - I presume this tool is also discussed here in this forum.
    My question is very simple (I presume):
    1. I installed Oracle SQL Developer 3.0.04.
    2. I added a new DB connection to a DB hosted in one of my servers in the LAN.
    3. However, when I am writing some SQL queries, I intend to use the "Explain Plan" feature, but it is being greyed out (disabled).
    4. How can I enable it back?

  • Connecting to HR schema in Oracle SQL Developer

    I have installed Oracle sql developer 3.2 version.And I dont have oracle client installed.
    Can I connect to HR schema with this set up.
    If yes ,please suggest me the credentials.
    Thanks.

    You do not need any oracle client installed, you do however need a database somewhere to connect to.
    The credentials you require would be for this database, and so we cannot help you get them.
    If you have a DBA that manages your databases ask him for the credentials.
    If you are on your own and just want to try out something, your best option is to install an Oracle XE on your own system, then you can connect with the defaults SQLDeveloper already has when creating a new connection (the system password will be set during database installation so note it down), then you can play with your newly installed database.

  • SQL Server database (read-only mode) in Oracle SQL Developer

    Hello,
    I connected SQL server database with Oracle SQL Developer 3.2.10.09, everything looks good except i can only browse data, i cannot change data in tables cannot insert new or delete rows. Query is also disabled (i got message: Query Builder is not supported for this connection type.) I used Third Party JDBC Drivers - jtds-1.2.6.jar as my connection to SQL server. Is there a way to change data in tables?
    Thank you.

    AFAIK editing table data in the grid is only possible with an Oracle database. On MS SQL you'll have to use update statements in the worksheet.
    Hope that helps,

  • 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.)
