找到数据库连接的jar:
terajdbc4.jar
mysql-connector-java-5.1.6-bin.jar
jtds-1.2.5.jar


1.In SQL Developer choose Tools -> Preferences...
2.Expand the "Database" option in the left hand tree
3.Click on "Third Party JDBC Drivers"
4.Click on "Add Entry..."
5.Navigate to your third-party driver jar file and choose OK

然后就可以连接其他数据库了。


[color=red]问题:连接其他数据库之后，工具依然没有自动提示功能。[/color]
