Oracle SQL 开发者和 PostgreSQL

Question

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?

Answer 1

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? .

Answer 2

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.

Answer 3

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

Answer 4

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.

Answer 5

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.

Answer 6

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.)

Answer 7

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.

Answer 8

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;

Answer 9

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

Answer 10

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
