I am using Oracle 11g. I had exported data using the installed version of SQL Developer to a sql file called "export.sql". Now, I have downloaded the new version which is 3.1.07 and when I try to import data by clicking on the tree view and choosing Tables | Import Data and navigating to "export.sql", I get the following error:
no readers are registered for the sql type
When I first started the application it asked for the path to java.exe and I have shown that path and application started. I have the started the application from the path where it was downloaded (C:\users\kaushik\Downloads\sqldeveloper)
You can call the file directly from sql developer.
Example: If you saved you file to c:\Oracle\MyBackups\Export.sql
Then from within Sql Developer, connect to your database and use the sql command:
#C:\Oracle\MyBackups\Export.sql
and that will execute the Export.Sql script.
If you have a valid SQL file, you simply need to execute the script. Open the file (File | Open and navigate to export.sql), hit the Run Script button (F5 on Windows), and choose the connection you want to use. The Data Import Wizard supports a number of different file formats (Excel, CSV, etc.). It doesn't support SQL files. If you want to ask the developers why they don't support SQL (or why they use the general file navigation dialog rather than using different dialogs for different sorts of files) you can ask them over in the SQL Developer forum on OTN. I assume the problem is that most SQL scripts contain much more than simple INSERT statements and it would be challenging to figure out whether any particular script was actually just a bunch of INSERT statements that could be used to import data.
Yes, SQL Developer is written in Java so you need to have an appropriate version of the JVM installed. Different SQL Developer download options include a bundled JVM or you can download a smaller file and use an already installed JVM.
One of oracle client tools to make session to database is sqlDeveloper and its graphical interface tool Programmed with Java Lang and its installed independently from oracle_home its a stand alone product and Of Course it needs SDK Or JDK to work
make sure to set the path and check it
read this link http://www.ehow.com/how_5127784_set-java-path.html
all of this if sql developer didn't run and other similar problem
this to answer
Is JDK is needed or what ? Yes
use sql Developer higher version
i am upgraded to Version 20.2.0.175
issue resolved

I have just implemented my DB Schema with Jetbrains new DataGrip IDE. The schema now exists on my DB server instance that is running locally.
In other IDE's I can save the work as a "Project" or save the SQL to a file. I don't see any option in DataGrip, except for Copy DDL, which I have tried and it copies my schema along with a lot of other stuff.
Is that the only option or am I supposed to do it through a PostgreSQL management tool. I want to save my work.
Thanks. Also, please don't just mark this to be closed. I have seen many other questions like this on StackOverflow. i.e. Asking how to perform some action on a tool related to software development.
You are in "default" project by default. Go to File/Project and create your own which can be opened later by File/Open recent, for example.
a little background, I really don't know any technical terms from Oracle. My company have a pre built machine and I'm trying not having to go there backup my files and lose a day of job because I cant.
Recently I'm learning how to use Oracle Designer (6i) to build a diagram and later a table so I can request it to be created... While using the software it requested to install some file for the repository... after doing it, It screwed up every Oracle product I was using... I couldn't connect to PLSQL or even the designer...
After fixing some registry to point to the right TNSNAME and manually adjusting PLSQL, I managed to access both. The problem in hand is in oracle Designer at the "Designer Editor", when I right click a table and select generate, the message bellow shows up
Message
-------
CDD-23564: The file "C:\ORACLE\DSG6I\BIN\cds61.dll" could not be loaded or does not exist.
Cause
-----
The specified file or one its dependent files could not be loaded.
This may be because a file has not been installed, or is not
correctly defined in the system registry.
As an example dependency, the Forms Generator files require the
Form Builder files installed as part of Developer.
Action
------
Check the registry settings for the location of the required
file. Also check the product and any required dependencies
e.g.Developer have been installed correctly.
If necessary, try reinstalling.
The dll mentioned IS and EXISTS on the mentioned folder.
Considering I don't have the Oracle Developer 6i intaller, what can I do? What registry entry should I update?
Designer 6 is long out of support. Oracle has a free tool, SQL Developer Data Model, which does not break.
Even Designer 9i was flaky and would crash at random intervals and poke along with larger schemas. Anything over hundred tables could take days to edit. Ah, good times...
I managed to fix the problem by copying and replacing the whole ORACLE_HOME\DSG6I folder (in my case c:\Oracle\DSG6I, for those confused in terms like me) and the oracle system registry (regedit > HKEY_LOCAL_MACHINE\SOFTWARE\Oracle) from a coworker machine!
Sqldeveloper 2.* had a very good tool to view database schema. here is the screen-shot of how it can be launched:
Was this tool removed from SqlDeveloper 3.* and is there something similar there?
P.S. I tried googling and reading manuals for some time, of course.
The latest versions of SQL Developer still have the data modeler.
http://www.oracle.com/technetwork/developer-tools/datamodeler/overview/index.html
here's a link that shows you, I use it almost daily in the latest version of sql developer (or at least 3.1.07 that I am using -->whoa they've updated to 3.2 I'll go get that later)
you can still goto Tools->Data Modeler but you can also OPEN and SAVE the datamodeler via the File->Data Modeler context menus (it seems to have been 'combined' with SQL DEVELOPER to the point where you save it independently).
If you go to VIEW->Data Modeler->Browser you can then create models etc and save them via the aforementioned menu item in SAVE.
I have an application that I can't get connected to my Oracle Database 11g Express Edition. I created a test database in this edition, and I can connect to the database fine using Oracle SQL Developer, create tables, views etc. However, I'm having a hard time getting connected via my application. Where is the connection information? In what file? I wanted to compare my connection info with what is set up in the SQL Explorer's file. I found all the *.ora files and renamed them to see if I could find what file (through the process of elimination) the connections were stored in, but I wasn't successful. Any help would be appreciated.
It was in a slightly different location for me than those listed above
\Users\[user]\AppData\Roaming\SQL Developer\system3.2.20.09.87\o.jdeveloper.db.connection.11.1.1.4.37.59.48\connections.xml
Assuming you have lost these while upgrading versions like I did, follow these steps to restore:
Open SQL Developer
Right click on Connections
Chose Import Connections...
Click Browse (should open to your SQL Developer directory)
Drill down to "systemx.x.xx.xx" (replace x's with your previous version of SQL Developer)
Find and drill into a folder that has ".db.connection." in it (for me, it was in o.jdeveloper.db.connection.11.1.1.4.37.59.48)
select connections.xml and click open
You should then see the list of connections that will be imported
If you don't find the connections.xml then right-click on Connections in the Connections view of SQLDeveloper, and choose Export connections.
It is stored in a file called connections.xml under
\Users\[User]\AppData\Roaming\SQL Developer\System\
When I renamed the file, all my connection info went away. I renamed it back, and it all came back. When I viewed the XML file, I found both test connection aliases, ports, usernames, roles, authentication types, etc.
In some versions, it stores it under
<installed path>\system\oracle.jdeveloper.db.connection.11.1.1.0.11.42.44
\IDEConnections.xml
For OS X my connection.xml files are in
/Users/<username>/.sqldeveloper/system<sqldeveloper_version>/o.jdeveloper.db.connection.<oracle_version?>/
With SQLDeveloper v19.1.0 on Windows, I found this as a JSON file in
C:\Users\<username>\AppData\Roaming\SQL Developer\system<versionNumber>\o.jdeveloper.db.connection
The file name is connections.json
SqlDeveloper stores all the connections in a file named
connections.xml
In windows XP you can find the file in location
C:\Documents and Settings\<username>\Application Data\SQL Developer\systemX.X.X.X.X\o.jdeveloper.db.connection.X.X.X.X.X.X.X\connections.xml
In Windows 7 you will find it in location
C:\Users\<username>\AppData\Roaming\SQL Developer\systemX.X.X.X.X\o.jdeveloper.db.connection.X.X.X.X.X.X.X\connections.xml
I found mine in
C:\Users\<user>\AppData\Roaming\SQL Developer\system2.1.1.64.45\o.jdeveloper.db.connection.11.1.1.2.36.55.30\connections.xml
If you have previously installed SQL Developer then it will store the connection details in the 'connection.xml' which will be located in below mentioned path.
C:\Users\Username\AppData\Roaming\SQL Developer\system3.1.07.42\o.jdeveloper.db.connection.11.1.1.4.37.59.48
Once you get that 'connection.xml'
try to import it into SQLDeveloper by right clicking to CONNECTIONS.
for macOS
/Users/joseluisbz/.sqldeveloper/system18.1.0.095.1630/o.jdeveloper.db.connection/connections.xml
In a simpler way open search window and search for connection.xml gives a right click on that file and select open file/folder location.
Once you get that connection.xml try to import it into SQLDeveloper by right clicking to CONNECTIONS.
To recover your password, locate the product_preferences.xml file in the following location:
C:\Users[username]\AppData\Roaming\SQL Developer\system*\o.sqldeveloper\product-preferences.xml
Then, search for the string db.system.id and copy the value of the v attribute. That is your decryption key to use when you are prompted to enter your decryption key on the Password Handling panel during the import processing on SQL Developer.
On linux systems:
~/.sqldeveloper/system<sqldeveloper_version>/o.jdeveloper.db.connection/connections.xml
I am trying to make a sqlite dump with SchemaSpy.
I got SchemaSpy up and running and was able to properly dump a MySQL database.
Now I have an .sqlite file (from an iOS application) and a sqlite driver from Christian Werner (http://www.ch-werner.de/javasqlite/overview-summary.html). An example over here explains how to work with that but to be honest - I don't understand what to do.
Is there someone who knows how I can use SchemaSpy on Windows? It is not necessary for me to use the GUI tool, though.
I also ran into this problem but finally made it work. You need the DLL for the SQLite library.
You can download it here, and then you can put it on system32 folder of your windows installation (C:\Windows\System32 for example)
Lastly, don't forget to specify the exact JDBC driver path:
java -jar… -dp "D:\SchemaSpy\driver\j2sdk1.4.2_03\jre\lib\ext\sqlite.jar" …
I'm the author of one of the articles you mentioned.
You need to compile the schemaspy JDBC driver. It was written for UNIX but someone sent the author notes on building it in a Windows environment. But there is a set of files for windows prebuilt with the sqlite.jar and .dll you need. Once you've got that on the classpath its straightforward.
If this is all too much for you, you can always fire up the sqlite3 CLI and use the .schema command to dump the tables, and set them up in a database you do know how to connect to. Or set up and Ubuntu VM ;)
I realize this is an old question, but for the record it's possible to make SchemaSpy use the Xerial SQLite JDBC driver, without a huge amount of difficulty, by rolling a new .properties file for it, following the instructions on http://schemaspy.sourceforge.net/dbtypes.html
All you really need to do is copy the existing sqlite.properties, renaming it to something like sqlite-xerial.properties and change the relevant lines; for example:
driver=org.sqlite.JDBC
description=SQLite-Xerial
driverPath=sqlite-jdbc-3.7.2.jar
The Xerial driver doesn't need the JNI DLL file and also has the benefit of picking up any configured FK relationships correctly - at least with the SQLite 3 database I've tested it against.
It does throw up some warnings when referencing table or column names that are also keywords, but that may be SchemaSpy's fault for not wrapping them in []. Or schema designers' faults for using keywords as table and column names :)
I do wonder why you need to get the sqlite driver. Just tell SchemaSpy your DB type is sqlite and you shall be okay. Something like
java -jar schemaSpy.jar -t sqlite -db <your file> -o <output>
It's usually best to grab the latest beta version of SchemaSpy. The invocation should be similar to running against MySQL except you specify your database type with -t sqlite and point the "database" to your .sqlite file.
The SQLite drivers use JNI for their implementation, so you'll need to make sure sqlite_jni.dll is in your PATH. To temporarily add it to your PATH in a Windows command prompt:
set PATH=%PATH%;directoryContainingTheJniDll
