select monkey_name from monkey

it will use animals schema by default.

What do I need to specify in connection URL above get such effect?


You can't put anything in the connection URL.

In Oracle each user has their own schema (even if doesn't contain any objects) and that is their default schema. Once logged in/connected, they can change their default schema with an


So you'd need to do the extra statement after connecting. It is possible to have a logon trigger on the user and/or database that will run this when they log in. I'd personally prefer an explicit statement when an application connects.

Default Schema in Oracle Connection URL, You can't put anything in the connection URL.

If you use C3PO you can make it do it when it checks the connection out.

As properties:

c3p0.preferredTestQuery=alter session set current_schema=animals

As Java code:

ComboPooledDataSource dataSource = new ComboPooledDataSource();
dataSource.setPreferredTestQuery("alter session set current_schema=animals");

Downside is this will happen every time the connection is taken out of the pool.

If you are using a JDBC connection yourself you could just do:

Connection connection = getConnection("jdbc:oracle:thin:@//server:1521/instance",   "username", "password");
connection.createStatement().execute("alter session set current_schema=animals"));

Only one schema can be specified using this syntax. And since 9.4 and possibly earlier versions on the JDBC driver, there is support for the setSchema(String schemaName) method.

What about the use of synonyms?

create synonym monkey for animals.monkey;

select monkey_name from monkey

How to configure Oracle to use a schema name different than the , I'd like to set default database schema in Oracle Connection URL jdbc:oracle:thin​:@<server>:<port1521>:<sid>.

  • This looks like something I can work around it. Create logon trigger with this statement might be my possible solution. Thanks.
  • I can now see that, this should be a solution. By having this logon trigger, I don't have to modify my sql. So all generic statements are still portable.

  • It's a good idea. However I find it is not definite, I am not sure if there are any side effects that could break things along the way.
  • This is usually the much better choice over altering the session since it shifts the problem from a behavioural aspect to a structural, which is much more robust.
  • Although this does work for most cases, in many corporate environments there will exist multiple application schemas in a single database. there will be a namespace collision if the original table names aren't created using prefixes. e.g. MY_APP_PREFIX_USER (usually more succint) many people find this ugly and would prefer the concept of a default schema over synonyms.
  • coderathet, that would be true if you used public synonyms. It is always advisable to use private synonyms as far as possible, which avoids such name collisions.
