How to connect to PostgreSQL with a specified schema using JDBC?

Connecting to PostgreSQL with a Specified Schema in JDBC

When establishing a connection to a PostgreSQL database using JDBC, it is often desirable to specify the schema that should be used for the session. This can help to organize the database and simplify queries.

Connection URL Configuration

To specify the schema when connecting to PostgreSQL using JDBC, you can utilize the connection URL. The following syntax can be used:

jdbc:postgresql://[host][:port]/[database_name]?currentSchema=[schema_name]

Example

For instance, to connect to a database named "mydatabase" using the "myschema" schema, you would use the following connection URL:

jdbc:postgresql://localhost:5432/mydatabase?currentSchema=myschema

JDBC Version Considerations

Note that the ability to specify the schema in the connection URL was introduced in JDBC version 9.4. If you are using an earlier version of JDBC, you will need to use alternative methods to set the search path or current schema.

Alternative Methods

If you cannot use the connection URL to specify the schema, you can also use the following alternative methods:

• Setting the search_path configuration parameter in the postgresql.conf file.
• Using the setSchema() method on the connection object.
