connect

Note: This is a Liquibase Pro feature, so you need a Liquibase Pro License Key to use it.

The Liquibase connect command allows you to test access to the database without requiring the changelog. It is available in Liquibase 4.25.1 and later.

Uses

This allows the user to test the connection’s readiness prior to including project workflows while simultaneously separating connection troubleshooting from workflow troubleshooting. This command works similarly to the status and history commands if they were to operate without a changelog.

Syntax

To run the connect command, specify the user name, password, and URL in the CLI, defaults file, as an environment variable, or any other standard method.

Run the connect command:

liquibase connect

Command arguments

Attribute Definition Requirement

--url=<string>

The JDBC database connection URL. See Using JDBC URL in Liquibase.

Required

--default-catalog-name=<string>

Name of the default catalog to use for the database connection

Optional

--default-schema-name=<string>

Name of the default schema to use for the database connection. If defaultSchemaName is set, then objects do not have to be fully qualified. This means you can refer to just mytable instead of myschema.mytable.

Tip: In Liquibase v4.23.0+, camelCase for defaultSchemaName works successfully. If you are on an earlier version, camelCase may not work as expected.

Note: The syntax liquibase.command.defaultSchemaName is valid for v4.19.0+. For prior versions, use defaultSchemaName.

Optional

--driver=<string>

The JDBC driver class

Optional

--driver-properties-file=<string>

The JDBC driver properties file

Optional

--password=<string>

Password to connect to the target database.
