update-sql

The update-sql command is a helper command that allows you to inspect the SQL Liquibase will run while using the update command.

Note: The update-sql command outputs the expected SQL of an update operation so that you can evaluate it. The command does not automatically check SQL for correctness and does not anticipate database deployment errors resulting from malformed SQL.

Uses

The update-sql command is used when you want to inspect the raw SQL before running the update 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.

Syntax

To run the update-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 properties from the command line.

Run the update-sql command:

liquibase update-sql --changelog-file=example-changelog.xml

Parameters

Global parameters

Attribute Definition Requirement

--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

--url=<string>

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

 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.

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

 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>

Precondition behavior

Preconditions are tags you add to your changelog or individual changesets to control the execution of an update based on the state of the database. You can specify the following attributes to control whether the update-sql command runs preconditions:

  • onSqlOutput: controls how preconditions are evaluated with the update-sql command for XML, YAML, and JSON changelogs.
  • onUpdateSql: controls how preconditions are evaluated with the update-sql command for formatted SQL changelogs.

You can specify the following values for onSqlOutput and onUpdateSql:

Value Description
FAIL When you run the update-sql command, Liquibase fails any preconditions.
IGNORE When you run the update-sql command, Liquibase ignores any preconditions.
TEST When you run the update-sql command, Liquibase evaluates preconditions normally.
