• Elapsed time in sql developer

  Hello
  
  For the script below how do we get the execution time for package below in sql developer
  

  set SERVEROUTPUT on
  set timing on
  VARIABLE OND REFCURSOR;
  execute PKG_ISR_CAF_CDNG_ORG_STRUCT.PROC_GETORGNODES_NEW_3959(10005543,'MANAGE', 10006746, :OND);
  PRINT OND;

  Hello

  This seems to be one of those cases where sheet SQL and SQL Developer * more behavior differ. Use of the "timing" on value in SQL * Plus will provide time for both execution of the procedure of a package, but also a call refcursor impression. A SQL Developer worksheet won't display any elapsed time for a SQL * more the print command, but if you replace your run with the following:

  VARIABLE OND REFCURSOR;
  BEGIN
  PKG_ISR_CAF_CDNG_ORG_STRUCT.PROC_GETORGNODES_NEW_3959(10005543,'MANAGE', 10006746, :OND);
  END;
  /
  PRINT OND;
  

  an elapsed time is then displayed for anonymous block.

  You want to maybe visit the SQL Developer Exchange and add a feature request for this feature if a request does not already exist.

• Oracle SQL Developer - File, Open, file name do not accept UNC path shape

  In Oracle SQL Developer, at least the file, open (dialogue), the name of the file (if not all the files / directory name) text box (s) is (are) not accepting, at least for me, the UNC form folders on network servers. The same UNC path (or UNC paths in general) work in the file / directory from all other Windows application name text box, I tried (from Windows 95 to Windows 7). Is there a way to do this? If not, it was intentional and where can I suggest this as a fix / development?
  
  I use Windows XP with SP3.

  Hi 906421-

  SQLDeveloper is written in java and runs on several operating systems. He uses (a derivative of) the standard java file picker. That said, I can see where it would be useful to add support for the UNC.

  You can add this to the Feature Requests to the SQL Developer Exchange. This is not only ensures we remember, but gives other users the chance to bring their vote for the feature and provides a forum for you (the user base) reflect on how you prefer it works.

• SQL Developer 3 - export truncates the XMLType data

  I am train to export data from and column XMLType & its getting truncated.
  I've tried insert formats, text, html, and csv. Big data gets truncated to 4000 characters, but its not exactly consistent.
  
  Is this all just not supported in SQL Developer, or am I missing something simple?

  You are right that there is currently a maximum of 4000 characters when exporting large data types.

  You can add your voice to feature requests SQL Developer using feature requests to the SQL Developer Exchange. This is not only ensures we remember, but also gives all users the chance to make their right to vote for features and provides a forum for you (the user base) to reflect on the way you prefer it works.

• How to add data to the table changed in sql developer at Apex and vice versa

  Hello

  I had tables of database with sql developer. But now, I have modified the database (new tables added + changed the data in the tables). However, in the Apex, I the old database. Is it possible to get the new Apex database with the data of the table changed so this database in both places (sql and apex developer) is exactly the same... Also the other way around.

  Thank you

  The database schema that contains the tables, is it associated with the workspace even you are searching through the APEX product t development?  Why I'm asking is, if they are the same schema, the tables that you MODIFIED should be appear in the sql for APEX workshop part.  Now reports and forms will NOT see the changes (unless you have actually added or updated definitions for column).

  Can you explain what exactly you were doing the SQL Developer to the tables in your schema?

  Thank you

• How to get SQL Developer 4.1 to display the query result?

  SQL DEV 4.0.3.16.84 execution of a SELECT statement is stored in a .sql file causes the window of the query result of pop-up indicating the result of a SELECT statement.  SQL DEV 4.1 is not to do so.

  Oops on my part; my SQL formatting has been the root cause.  I got used to insert split without any character of comment lines in front of them.  For example:

  ==================================================

  Select funny business;

  The foregoing indicates the behavior described.

  --==================================================

  Select funny business;

  With the dash double comment shows, the SQL works very well.

  This is different than previous versions of SQL Developer, but is probably better functionality.  I'll try to mark it as answered, but anyone with the admin should certainly do so if I can't.

• DB2 zOS supported in SQL Developer?

  I managed to connect to DB2 zOS by adding third-party JDBC drivers from IBM (db2jcc4.jar and db2jcc_license_cisuz.jar) in the SQL Developer preferences. During the connection, I get an error:

  DB2 SQL error: SQLCODE =-204, SQLSTATE = 42704, SQLERRMC = SYSCAT. SCHEMAS, DRIVER = 4.18.60

  The connection actually works, and I can execute SQL statements thereafter, however autocompletion and browse the list of tables is not, which makes it pretty useless.

  So is this a misconfiguration on my part or Developer SQL is supported by DB2 on zOS still?

  If this is the case, is there any plans/roadmap for at least a minimum of DB2 support?

  The 3rd part of database in Oracle SQL Developer is supported for help you migrate says 3 party in the Oracle database databases

• Can I connect SQL Developer to Essbase?

  I know that tools such as the table can connect to Essbase, but how can I connect Oracle SQL Developer to Essbase?

  You have not, I'm afraid.

  SQL Developer is a development tool for working with databases oracle that supports connections to a set of data bases third-parties for the purposes of specific to oracle migration.

  Third-party databases supported are listed in help, but from memory they are UDB DB2, MS SQl Server, Sybase, MySQL and Teradata.

  Developer SQL is not a tool of multiple databases.

• Bug in SQL Developer 4.0.2.15.21 or incompatibility with JDev 12.1.2 Extension SDK

  Submenus and submenu items added to a context menu NOT displayed in sql developer, but appear in JDev.

  Individual, added to a context menu items work correctly but submenus are not.

  1 Sql Dev 4.0.2.15.21 is based on the JDev 12.1.3 framework which is NOT yet publicly released

  2. the below example (based on JDev Extension SDK FirstSample) displays the contextual and submenu menu items and submenuitems correctly

  3. the same example in Sql Dev does NOT contain the submenu and submenu items. Is this a bug or an incompatibility between the frames?

  The starting point was the FirstSample of the latest version of the Extension SDK. I confirmed this example worked in JDev 12.1.2.0.l0 and Sql Dev 4.0.2.15.21

  It's what you see, correctly, in JDev

  Connection

  CustomSubMenu

  Custom submenu item1

  Custom submenu Item2

  The submenu and items are NOT displayed in Sql Dev

  Tables

  DEPT

  ESDK sample Action

  Custom element 1

  Custom element 2

  The following changes to the 'extension.xml' file for the sample in order to display the menu items popup extra on a node 'TABLE' of the browser database:

  1 removed the menu items and the main gallery

  2. Add a section 'rules '.

  "<-hooks of relaxation xmlns ="http://xmlns.oracle.com/ide/extension">."

  < rules >

  < rule id = "framework-a-object-node" type = "framework-a-node" >

  < Parameters >

  < param name = "node-class" value = "oracle.dbtools.raptor.navigator.impl.ObjectNode" / > "

  The JDev version I have is the 12.1.2 framework but Sql Dev, I was informed by the dev team Sql uses the 12.1.3 framework that is NOT yet accessible to the public.

  I do not know which of the three assumptions (or others) could be correct:

  1. something broken in the new 12.1.3 framework that works in the 12.1.2 framework

  2. the rules of XSD schema changed to specify submenus

  3. something broken or changed in the port of Sql Dev/use of the framework

  I hope that you will have the answer you are looking for on the side of the House JDeveloper.  From the point of view of pure Java, however, I tend to fall back on the generalization that the byte code and JVM, any extension you are building from Java source - whether you use a 32-bit JDK or 64 bits - can be run on a virtual machine JAVA 32 bit or 64 bit.  It should not matter: the building where you can then deploy anywhere.

• Extension of SQL Developer Java does not

  Hello

  I developed a small extension of Java to start the SQL Developer via command line and put some parameters such as the server name, user and password to create a connection when you start.

  THS connection will be deleted when closing.

  This extension was working fine until the 3.0.2 version and does not work with version 4.0.2.

  My question: are there changes in the load of an extension?

  Any help would be appreciated, thanks.

  
  

  I developed a small extension of Java to start the SQL Developer via command line and put some parameters such as the server name, user and password to create a connection when you start.

  This extension was working fine until the 3.0.2 version and does not work with version 4.0.2.

  My question: are there changes in the load of an extension?

  Yes - there are MAJOR changes and they include the use of "lazy" loading of extensions.

  See note on the main page of Oracle extension exchange.

  http://www.Oracle.com/technetwork/developer-tools/SQL-Developer/Extensions-083825.html Special Note regarding Extensions developed prior to SQL

  Developer v4.0:

  With the new version of SQL Developer 4.0, an extension that was written for an earlier version of the SQL Developer will no longer work. Developer SQL is based on the JDeveloper Framework. We have updated the framework to be up-to-date with the JDeveloper 12 c version. With JDeveloper 11 g 2, they switched to an OSGI framework. The JDeveloper team issued instructions to update your extensions to be compatible with the new framework and SQL v4.0 developer.

  Note that first sentence than the previous expansions 'won't work' If you use them in 4.x

  It also appears to be bugs or incompatibilities between the extension of JDeveloper published SDK and the "new" version Sql Dev 4.x uses. The public is 12.1.2, and is one that is available for download for use in the development of an extension. SQL Dev uses version 12.1.3 and who has NOT yet been published.

  I have a new thread posted recently to ask about any aspect of this compatibility, but have not yet had all the answers:

  https://community.Oracle.com/thread/3570408

  A few simple extensions, perhaps yours, may only need a small change in the file "extension.xml" use appropriate brackets.

  Other extensions will require additional changes. One of the main changes is the new ESDK of "lazy" loading of extensions use.

  Some additional info is available on the Java.net site:

• Integrate SQL Developer with IBM's Clearcase Version control

  Hello

  I explored the part of version control for SQL code by incorporating my SQL with Clearcase from IBM Developer. So far I have not been successful with it, I managed to remove the SVN Version control options, but I am not able to use it for my Clearcase link. Could I know please if there is any plugin available from Oracle for this to do. If it please help & drop your suggestions.

  
  Thank you

  Michael ([email protected])

  Hi Julien,

  There is ClearCase comes available for JDeveloper extension versions, and as any given SQL Developer release some releases JDeveloper, you may be able to find an appropriate version of the extension for your use case.  Looking for ClearCase in the center of update JDev:
  http://www.Oracle.com/ocom/groups/public/@OTN/documents/WEBCONTENT/131167.XML

  Of course, ClearCase is Nolisted in the release notes for SQL Developer as a supported Version control system:

  http://www.Oracle.com/technetwork/developer-tools/SQL-Developer/downloads/sqldev-releasenotes-v4-1925251.html

  If you want to give it a go, however, here's what I did to install a ClearCase plug-in for my 4.0.1 Developer SQL...

  1. check the SQL Developer Help > about > Extensions for the version of oracle.jdeveloper.vcs (12.1.3.2.41.140207.1351)

  2 downloaded vcs - clearcase_bundle.zip (12.1.2.0.40.66.68 is the closest available JDev version)

  3. in the zip file, modify or replace the value of the property maxVersion in the META file - INF\bundle.xml (from 12.1.2.0.40.66.68 to 12.1.3.2.42.99.99)

  4. install the zip: Tools > features... > Check for Updates (top-right) > install from a Local (radio button) file...

  5. now, ClearCase will be available from the main tool bar: team > ClearCase

  I don't have a ClearCase installed on my machine, so that's as far as I could go.  I hope that you will still make progress.

  Kind regards

  I try with model db (DB empty, just a single table), but the error is same. However, if I try to copy the acronym tabele from SQL Server to Oracle it works fine...

  I guess it's something with the configuration, but beacause I am new in Oracle still have no idea...

  Any help would be much appreciated

  I thank in advance

  Stefan

  Hello Stefan,

  did you create the repository Migration of your database to Oracle (Tools-> Migration-> repository management)?

  The SS2K5ALLPLATFORM package is usually created when you add the migration of the Oracle database repository and it contains the function StageCapture.

  So please make sure that you have created a repository of migration in an Oracle database and associate it with the first step of your migration.

• How to install the driver jdbc for sql server 2005 in sql developer 4.0?

  
  Hallo all

  I need to access the tables in a MS SQL Server 2005 database.

  The JDBC driver is possible.

  How to install this driver?

  Thanks a lot for your messages.

  Hello

  It's the documentation-

  Database: third-party JDBC Drivers

  The component drivers JDBC third party specifies drivers to use for connections to the third-party databases (non-Oracle), such as IBM DB2, MySQL, Microsoft SQL Server or Sybase Adaptive Server. (You don't need to add a driver for connections to Microsoft Access databases.) To add a driver, click Add an entry and select the path for the driver:

  For Microsoft SQL Server or Sybase Adaptive Server: jtds - 1.2.jar, which is included in the download of jtds - 1.2 - dist.zip

  To find a specific third-party driver, visit the appropriate site (for example, http://www.mysql.com for MySQL Connector/J JDBC driver for MySQL, http://jtds.sourceforge.net/ for the for Microsoft SQL Server and Sybase Adaptive Server jTDS driver, or search for Teradata JDBC driver to http://www.teradata.com/ ). For MySQL, use the driver in MySQL 5.0 not 5.1 or a later version with the version of SQL Developer 1.5.

  You must specify a third-party driver or install a driver using the check for updates feature before you can create a connection to a database to third parties of the associated type. (See the tabs to create connections to the databases of third parties in the Create/Edit/Select database connection dialog box).

  Alternative:

  As an alternative to the use of this preference, you can click Help, and then search for the updates install the for Microsoft SQL Server JTDS JDBC driver and the driver of JDBE of MySQL as extensions.

  Kind regards

• question about generated an offline source SQL server 2008 given by Oracle SQL developer

  Hi friends,

  I followed the tutor to the migration of a database server Microsoft SQL to Oracle Database 11 g by Developer sql Version 3.2.20.10 in the window.

  I can migrate the code examples in the oracle database.  The code example has two file: Capture and data. Under the folder data, there are two parts. one is designated as folder under oracle and rest is data add log files.

  When I migrated my database of sql server 2008 in oracle 11. I can objects only sql migrated to oracle but failed to load data during data file missing.

  Thank you

  newdaa

  Use SQl developer offers 2 options to move the data, online and offline data movement. When you call the batch file to load data offline you must also make sure that you collected the data first to the SQL server side using the data to extract batch files that create the DAT files with the content. The content is written in flat files using the file unload_scripts.bat-online check if you have this kind of file, and then copy the entire script to SQL Server folder, and run the script of unloading it.

  It will create the dat files that you will then need to load the data into the Oracle database.

• Issue of Oracle SQL Developer when you use VPN (Cisco)

  All,
  
  We have a somewhat obscure issue with connectivity SQL Developer to our databases of the laptop has distance from the employee.
  
  The database is hosted inside our firewall and when the employee is trying to connect to the database that it receives the following error message:
  + "Encountered error: an error has occurred to perform the requested operation: the network adapter could not establish the connection." Code provider 20 "+"
  
  I think maybe I saw the error at some point as well...
  Status: Failure-Test failed: IO error: the network adapter could not establish the connection
  
  Note: It gets this error when you are connected to our VPN & so that it can connect through SQL * more on that same basis. It gets the error without worrying if he uses the option to enter tnsnames in SQL Developer or if it uses the "basic" connection type
  
  What is interesting, is that if he disconnects the VPN, will turn off its wireless connectivity, then hard-wire in our network, it can connect, without issue.
  
  The strangest part for me, is that although it cannot connect to the database using SQL Developer, it can connect through SQL * more. It can ping the IP source address very well, he can tnsping database without problem, it can connect through SQL * Plus, it just cannot connect through SQL * Developer. Since SQL * more and tnsping work, I know that it can access the db server through port 1521, so I don't think it's a problem of port.
  
  Another weird thing: when it connects to our network via a 'old' virtual private network (VPN open) there is no problem.
  
  His machine is Windoz 64 bit (HP laptop) and it uses the latest version of the SQL Developer and a JAVA virtual machine.
  
  Also interesting: I also have a Windoz 64 bit computer laptop (Lenovo) and I don't have the same issues, as it does. I am however running an older version of SQL Developer and probably an older JVM.
  
  I dug around a bit, looks like maybe it has something to do with IPv6? No idea what to do next, except have my network guy look at the logs of firewall to try to grasp where the connectivity has been ignored.
  
  Any ideas or suggestions would be appreciated. I tried all sorts of things (giving him my file tnsnames.ora and sqlnet.ora, manually editing these files, try IP addresses instead of host names, host names I tried with the doman.org extensions, etc.).
  
  Still, any suggestion would be appreciated and I thank very you much.

  If it is IPv6, you can try adding

  AddVMOption -Djava.net.preferIPv4Stack=true
