changelog-sync-to-tag-sql

changelog-sync-to-tag-sql is a helper command that produces the raw SQL that Liquibase would run when using the changelog-sync-to-tag command to mark all undeployed changesets associated with the specified tag as executed in your database.

Uses

The changelog-sync-to-tag-sql command is typically used when you want to inspect the SQL Liquibase will use to baseline a new database environment.

It is best practice to inspect any SQL that Liquibase would run when using the changelog-sync-to-tag command so you can review any changes the command would make to your database before running it. The changelog-sync-to-tag command marks all changesets starting with the first changeset at the top of the changelog file and moving down to the changeset up to and including the tag.

Note: If you don’t have any tag specified in your changelog file, add it by using the tagDatabase Change Type as follows:

<changeSet id="13.1" author="liquibase">
    <tagDatabase tag="version_2.0"/>
</changeSet>

Tip: When you run changelog-sync-to-tag-sql, check whether you specified the correct tag and which changesets were affected. (If you specify a tag that Liquibase cannot find in your changelog, the changelog-sync-to-tag command adds new rows in the DATABASECHANGELOG for all changes.)

Syntax

Before running the changelog-sync-to-tag-sql command, specify the driver, classpath, and URL in the Liquibase properties file. For more information, see Create and Configure a liquibase.properties File. You can also specify these properties in your command line.

Next, run the changelog-sync-to-tag-sql command:

liquibase changelog-sync-to-tag-sql --tag=myTag --changelog-file=example-changelog.xml

Note: The --tag=myTag syntax was added in Liquibase 4.4. If you use an older version, specify your tag as a positional argument: <command> myTag.

Parameters

Global parameters

Attribute Definition Requirements

--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

Attribute Definition Requirement

--changelog-file=<string>

The root changelog

 Required

--tag=<string>

The tag identifying which tagged changesets in the changelog to evaluate. Specify as --tag=myTag. Positional format <command> <tag> deprecated in 4.4+.

 Required

--url=<string>

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

 Required

--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

--output-default-catalog=<true|false>

Control whether names of objects in the default catalog are fully qualified or not. If true, they are. If false, only objects outside the default catalog are fully qualified. Default: true.

 Optional

--output-default-schema=<true|false>

Control whether names of objects in the default schema are fully qualified or not. If true, they are. If false, only objects outside the default schema are fully qualified. Default: true.

 Optional

--password=<string>

Password to connect to the target database.

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

 Optional

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.
