update-one-changeset-sql

Last published July 28, 2025

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

The update-one-changeset-sql command is a helper command that allows you to inspect the SQL Liquibase will run to deploy the changeset specified in the update-one-changeset command. It is only available for Liquibase Pro users.

Uses

The update-one-changeset-sql command is useful when you want to inspect the raw SQL that Liquibase uses to deploy your changeset when you run the update-one-changeset command, so that you don't unintentionally make a mistake.

Syntax

Before running the update-one-changeset-sql command, gather the following information from your changelog:

  • The author of the changeset you want to deploy.

  • The ID of the changeset you want to deploy.

  • The file path and name of the changeset you want to deploy.

Then run the update-one-changeset-sql command, with your information:

liquibase update-one-changeset-sql --changelog-file=example-changelog.xml --changeset-id=2 --changeset-author=anotherdev --changeset-path=example-changelog.xml

For more command-specific help, type liquibase update-one-changeset-sql --help into the command prompt.

Note: The username and password attributes are not required for connections and systems which use alternate means of authentication. Also, you can specify database credentials as part of the url attribute.

Parameters

Global parameters

Parameter

Definition

Requirement

--license-key=<string>

Your Liquibase Pro license key

Required

--output-file=<string>

File path to where the command output will be written. If not specified, output goes to STDOUT. See --output-file.

Optional

Command parameters

Parameter

Definition

Requirement

--changelog-file=<string>

The root changelog

Required

--changeset-author=<string>

The name of the author for the changeset. Supports * as a wildcard.

Required

--changeset-id=<string>

The changeset ID from the changelog.

Required

--changeset-path=<string>

The path to the changelog containing the changeset you want to target. For example, you may have a root changelog (root.sql) and a child changelog (child.sql). To target a specific changeset in child.sql, specify --changeset-path=child.sql.

If root.sql uses include, includeAll, or sqlFile to reference child.sql, you must also specify --changelog-file=root.sql (file and path are different).

If root.sql does not reference child.sql, you must also specify --changelog-file=child.sql (file and path are the same).

If you only have one changelog, then --changelog-file and --changeset-path must also be the same.

Required

--url=<string>

The JDBC database connection URL.

Required

--change-exec-listener-class=<string>

Fully-qualified class which specifies a ChangeExecListener. For more information, see Implementing a Custom ChangeExecListener Class with Liquibase and ChangeExecListenerCommandStep.

Optional

--change-exec-listener-properties-file=<string>

Path to a properties file for the ChangeExecListener class. For more information, see Implementing a Custom ChangeExecListener Class with Liquibase and ChangeExecListenerCommandStep.

Optional

--context-filter=<string>

Specifies the changeset contexts to match. Contexts are tags you can add to changesets to control which changesets are executed in any particular migration run.

Note: If you use Liquibase 4.23.0 or earlier, use the syntax --contexts instead of --context-filter.

Optional

--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.

Note: In the properties file and JAVA_OPTS only: in 4.18.0 and earlier, specify this parameter using the syntax defaultSchemaName. In 4.19.0 and later, use the syntax liquibase.command.defaultSchemaName.

Note: In Liquibase 4.12.0 and later, you can use mixed-case schema names if you set --preserve-schema-case to true. However, in Liquibase 4.12.0–4.22.0, the Liquibase validator still throws a DatabaseException error if you specify a mixed-case value of defaultSchemaName. In 4.23.0 and later, the Liquibase validator accepts any casing.

Optional

--driver=<string>

The JDBC driver class

Optional

--driver-properties-file=<string>

The JDBC driver properties file

Optional

--label-filter=<string>

Specifies the changeset labels to match. Labels are tags you can add to changesets to control which changesets will be executed in any migration run.

Optional

--password=<string>

Password to connect to the target database.

Tip: It is best practice to store sensitive data in a Secrets Management tool with Liquibase Pro.

Optional

--username=<string>

Username to connect to the target database.

Tip: It is best practice to store sensitive data in a Secrets Management tool with Liquibase Pro.

Optional

Output

When successful, the update-one-changeset-sql command produces the following output:
