Is there a way to set the default schema for a Database connection in Oracle SQL Developer version 4+? I see this link for previous versions:
http://www.javaforge.com/project/schemasel
...but I can't figure it out for Oracle SQL Developer version 4.
The way to do this at the tool level would be to run a session startup script.
Create a text file 'logon.sql' with the script "alter session set current_schema = yourschema;"
Save it anywhere - I recommend saving it somewhere in your database install location.
In SQL Developer go to Tools -> Preferences -> Database
Check the box for "Run connection startup script on each new database connection"
Browse and select the above file.
That should make you default to that schema every time you login.
I have got this problem in local instance of SQL Server 2008 R2 on my machine. There are several databases on this instance. But I am not able to see any of them from the object explorer.
I am able to query my databases from the new query window. But not able to see any of them.
Whenever I try to explore the databases I get this error :
Database 'msdb' cannot be opened. It has been marked SUSPECT by recovery. See the SQL Server errorlog for more information. (Microsoft SQL Server, Error: 926).
I have tried
Refreshing the connection
Reconnecting the connection
Restarting the service Sql Server (MSSQLSERVER).
Restarting the SQL Server Management Studio
Restarting my machine
I have also tried combinations of above, but nothing works.
My operating system is Windows 7 Ultimate (64 bit).
SQL Server Management Studio Version is 10.50.2500.0.
I found my answer in this link.
EDIT : Including both the solutions from link because of possible Linkrot in future.
Login with sa account, for both the solutions.
Solution 1
Open new query window
EXEC sp_resetstatus 'DB_Name'; (Explanation :sp_resetstatus turns off the suspect flag on a database. This procedure updates the mode and status columns of the named database in sys.databases. Also note that only logins having sysadmin privileges can perform this.)
ALTER DATABASE DB_Name SET EMERGENCY; (Explanation : Once the database is set to EMERGENCY mode it becomes a READ_ONLY copy and only members of sysadmin fixed server roles have privileges to access it.)
DBCC checkdb('DB_Name'); (Explanation : Check the integrity among all the objects.)
ALTER DATABASE DB_Name SET SINGLE_USER WITH ROLLBACK IMMEDIATE; (Explanation : Set the database to single user mode.)
DBCC CheckDB ('DB_Name', REPAIR_ALLOW_DATA_LOSS); (Explanation : Repair the errors)
ALTER DATABASE DB_Name SET MULTI_USER; (Explanation : Set the database to multi user mode, so that it can now be accessed by others.)
Solution 2
In Object Explorer --> The opened connection item --> rightclick --> Stop
Open Control Panel --> Administrative Tools --> Services
Select Sql Server (MSSQLSERVER) item from services --> rightclick --> Stop
Open C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA
Move MSDBData.mdf & MSDBlog.ldf to any other place
Then Copy this Files Again from new place and put it in older place
C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA
In opened connection in object Explorer --> rightclick --> Start
Then Refresh DataBase.
Then you can Detach the MSDB File
The 2nd solution worked for me.
Note : I had to get "msdb" database mdf and ldf files from another working machine to get it working.
What instantly fixed my issue was to replace existing MSDBData.mdf & MSDBlog.ldf files
in C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQL\DATA. I got these 2 files copied from another working machine, Stopped the SQL service running in my machine, removed the above existing 2 files from their location and added the new 2 copied. Once I restarted the service , issues has been fixed.
Try this
Set the database into single user mode:
Alter database dbname set single_user
Now set the database into emergency mode:
Alter database dbname set emergency
Repair missing log file or corrupted log file with data loss.
DBCC CHECKDB ('dbname', REAPIR_ALLOW_DATA_LOSS)
Now set the db in multi user mode;
Alter database dbname set multi_user
You may loss the data by using this command. It also depends on client's approval. To avoid this you may use some other dedicated software ( As Mentioned here ) to recover from suspect mode.
I want to install SQL Server 2008 R2, so I need to put "server name", I tried my computer name but I got an exception, would you tell me how to find it please
and this is the exception ![enter image description here][2]
You can use .\SQLEXPRESS as the server name.
Check this link
EDIT:-
From the comments below posted by the user(thought that it is useful)
You can install SQL Server as an instance, which allows you to run
multiple environments on the same machine (ie. localhost\dev and
localhost\prod). If you install MSSQL Server Express, it defaults the
instance name to localhost\SQLEXPRESS
Use . as the server name. Or
From the server manager: Administration tools > Server Manager. You can get the computer name.
Use .\SQLEXPRESS
or
Use REVAN-PC\SQLEXPRESS
REVAN-PC is my System Name
Go to Start
write in search box: ODBC
Go to system DSN tab
click on Add...
select SQL server option and finish
Go to 3th box (server:) and see your server!
Try using (local) as server name. I had the same problem and after few attempts of connecting,(local) just came by default in the server name field.
I'm trying to connect to a PostgreSQL 9.1 database using Oracle SQL Developer 3.0.04, but I'm not having any success so far.
First, if I add a third party driver on preferences, when adding a new connection there's no tab for PostgreSQL (it works fine for MySQL though). I'm using a JDBC4 version 9.1 driver, but I tried a JDBC3 of the same version and still get the same thing.
Second, there's nothing like manual configuration tab when adding a new connection. The closest is the Advanced option on Oracle tab, where I can provide a custom URL, but it fails because complains about the selected Driver (of course).
Finally, I got connected importing a connection from an XML file (contents below), but it displays only my schemas and doesn't show my tables inside them.
So, my question is: does Orable SQL Developer support PostgreSQL connections? Is there any other way to have my tables being displayed in the ObjectViewer?

Oracle SQL Developer 4.0.1.14 surely does support connections to PostgreSQL.
download JDBC driver for Postgres (http://jdbc.postgresql.org/download.html)
in SQL Developer go to Tools → Preferences, Database → Third Party JDBC Drivers and add the jar file (see http://www.oracle.com/technetwork/products/migration/jdbc-migration-1923524.html for step by step example)
now just make a new Database Connection and instead of Oracle, select PostgreSQL tab
Edit:
If you have different user name and database name, one should specify in hostname: hostname/database? (do not forget ?) or hostname:port/database?.
(thanks to #kinkajou and #Kloe2378231; more details on https://stackoverflow.com/a/28671213/565525).
I've just downloaded SQL Developer 4.0 for OS X (10.9), it just got out of beta. I also downloaded the latest Postgres JDBC jar. On a lark I decided to install it (same method as other third party db drivers in SQL Dev), and it accepted it. Whenever I click "new connection", there is a tab now for Postgres... and clicking it shows a panel that asks for the database connection details.
The answer to this question has changed, whether or not it is supported, it seems to work. There is a "choose database" button, that if clicked, gives you a dropdown list filled with available postgres databases. You create the connection, open it, and it lists the schemas in that database. Most postgres commands seem to work, though no psql commands (\list, etc).
Those who need a single tool to connect to multiple database engines can now use SQL Developer.
Oracle SQL Developer doesn't support connections to PostgreSQL. Use pgAdmin to connect to PostgreSQL instead, you can get it from the following URL
http://www.pgadmin.org/download/windows.php
I managed to connect to postgres with SQL Developer.
I downloaded postgres jdbc driver and saved it in a folder.
I run SQL Developer -> Tools -> Preferences -> Search -> JDBC
I defined postgres jdbc driver for the Database and Data Modeler (optional).
This is the trick.
When creating new connection define Hostname like localhost/crm? where crm is the database name. Test the connection, works fine.
If there is no database with the same name as the username, then clicking "Choose Database" will fail with an error like "Status : Failure -FATAL: database "your_username" does not exist"
To work around this, put 5432/database_name? in the Port field, where 5432 is the port of your Postgres instance and database_name is the name of at an existing database that your_username has access to. Then click "Choose Database" again and it should work. Now you can choose the database you want and remove the extra /database_name? from the Port field.
I think this question needs an updated answer, because both PostgreSQL and SQLDeveloper have been updated several times since it was originally asked.
I've got a PostgreSQL instance running in Azure, with SSLMODE=Require.
While I've been using DBeaverCE to access that instance and generate an ER Diagram, I've gotten really familiar with SQLDeveloper, which is now at v19.4.
The instructions about downloading the latest PostgreSQL JDBC driver and where to place it are correct. What has changed, though, is where to configure your DB access.
You'll find a file $HOME/.sqldeveloper/system19.4.0.354.1759/o.jdeveloper.db.connection.19.3.0.354.1759/connections.json:
{
"connections": [
{
"name": "connection-name-goes-here",
"type": "jdbc",
"info": {
"customUrl": "jdbc:postgresql://your-postgresql-host:5432/DBNAME?sslmode=require",
"hostname": "your-postgresql-host",
"driver": "org.postgresql.Driver",
"subtype": "SDPostgreSQL",
"port": "5432",
"SavePassword": "false",
"RaptorConnectionType": "SDPostgreSQL",
"user": "your_admin_user",
"sslmode": "require"
}
}
]
}
You can use this connection with both Data Modeller and the admin functionality of SQLDeveloper. Specifying all the port, dbname and sslmode in the customUrl are required because SQLDeveloper isn't including the sslmode in what it sends via JDBC, so you have to construct it by hand.
I got the list of databases to populate by putting my username in the Username field (no password) and clicking "Choose Database". Doesn't work with a blank Username field, I can only connect to my user database that way.
(This was with SQL Developer 4.0.0.13, Postgres.app 9.3.0.0, and postgresql-9.3-1100.jdbc41.jar, FWIW.)
Oracle SQL Developer 2020-02 support PostgreSQL, but it is just the basics by adding postgreSQL driver under jdbc dir and configure by adding as a 3rd party driver.
The supported functionality:
multiple databases which can be selected at connection definition
CRUD operations like query tables
scheme operations
basic modelling support: show tables without pk, fk, connections
Not supported functionalities:
no table or field completion
no indexes are shown in a tab
no constraints are shown in a tab like: fk, pk-s, unique, or others
no table or field completions in the editor
no functions, packages,triggers, views are shown
The sad thing is Oracle should only change the queries behind this view in case of PostgreSql connections. For example for indexes they need to use this query: select * from pg_catalog.pg_indexes;
Except that it will not work if your user name and database name are differents. It sounds like an SQLDeveloper bug and i can't find any workaroud
Maybe there are some bugs in Oracle SQL Developer when it connect to the postgresql.However I connect postgresql with navicat successfully.(My postgresql username and database name are different
host= localhost/postgres? worked for me if you need a schema/database use:
localhost/postgres?currentSchema=myschema
ex: localhost/postgres?currentSchema=public
once connected, you can also use the
[Choose Database] button and pull down
sql developer postgres jdbc url for the rest of us
I successfully use EF4 to build my database from scratch. My database is an SQL EXPRESS database file. I can manage this one with Sql Server Management Studio. So far so good.
I noticed that if I open my database with the Server Explorer in Visual Studio, the next time I run the application I got errors.
I also noticed that a new log file has been created. So now I have 2 log files.
Below is my connectionstring:
<add name="DocumentManagerEntities"
connectionString="data source=.\SQLEXPRESS2008;Initial Catalog=DocumentManagerDB;AttachDBFilename=|DataDirectory|DocumentManagerDB.mdf;Integrated Security=SSPI;MultipleActiveResultSets=True"
providerName="System.Data.SqlClient" />
What's wrong?
Thank you very much.
That maybe because multiple applications are trying to use your database at once. You need to close one connection to open another.
This article notes that
SQL Server Express Edition allows only a single connection to an .mdf
file when you connect with a connection string that has User Instance
set to true.
Further more
When you connect to a local database project, Visual Web Developer
connects to the SQL Server Express Edition database with user
instances enabled, by default. For example, the following code example
shows a typical connection string used by Visual Web Developer to
connect to a SQL Server Express Edition database.
