`update-to-tag-sql`

The update-to-tag-sql command is a helper command that inspects the SQL Liquibase will run while using the update-to-tag command.

Uses

The update-to-tag-sql command is used to inspect the raw SQL before running the update-to-tag command, so you can correct any issues that may arise before running the command. Liquibase uses the raw SQL to apply database changes you have added to the changelog file based on the tag specified.

Syntax

To run the update-to-tag-sql command, specify the driver, classpath, and URL in the Liquibase properties file. You can also specify them from the command line.

Then run the update-to-tag-sql command:

liquibase update-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.

Global arguments

Tip: For best results, specify all commands and parameters in the --kebab-case format in the CLI. If your preference is camelCase, it also works in the CLI.

Attribute	Definition	Requirement
`--output-file`	File path to where the command output will be written. If not specified, output goes to `STDOUT`	Optional

Command arguments

Attribute	Definition	Requirement
`--changelog-file` *	The root changelog	Required
`--tag`	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`	The JDBC database connection URL. See Using JDBC URL in Liquibase.	Required
`--change-exec-listener-class`	Fully-qualified class which specifies a ChangeExecListener	Optional
`--change-exec-listener-properties-file`	Path to a properties file for the `ChangeExecListenerClass`	Optional
`--contexts`	Specifies the changeset contexts to match. Contexts are expressions you can add to changesets to control which changesets are executed in any particular migration run.	Optional
`--default-catalog-name`	Name of the default catalog to use for the database connection	Optional
`--default-schema-name`	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`	The JDBC driver class	Optional
`--driver-properties-file`	The JDBC driver properties file	Optional
`--label-filter`	Specifies the changeset labels to match. Labels are tags you can add to changesets to control which changeset will be executed in any migration run.	Optional
`--output-default-catalog`	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`	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`	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`	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

*Liquibase checks the changelog and any nested changelogs for the definitions of the changesets to update.

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.
